The conveyor belt vulcanizing machine (conveyor belt joint machine) produced by Suzhou Arphu Industiral Co., Ltd. includes two types of models, rhombus and rectangular. Among them, the DLCBV rhombus model is currently the mainstream pattern in the market. Its advantages include high joint strength, low stress on the roller, long joint life (construction according to vulcanization process, joint life is equal to the conveyor belt life), and long effective joint length of a single vulcanizing machine. Currently, the mainstream angle for diamond-shaped joints is 22 degrees. In contrast, the joint strength of rectangular joints is relatively poor. Due to the parallel angle with the roller when passing through, it experiences higher stress and has a shorter joint lifespan. However, in some specific occasions, the DLCBV rectangular vulcanizing machine is irreplaceable, such as for ultra-short distance conveyor belts and overhead car conveyor belts. Due to limitations in conveyor position and construction space, rhombus shape conveyor belt vulcanizing machines cannot be used for construction, so rectangular vulcanizing machines can be used instead. In addition, rectangular heating plates are also used for the DLBRV repair vulcanizing machine. Both of these vulcanizing machines produced by Suzhou Arphu Industiral Co., Ltd. adopt advanced technology and a fully automatic precision digital display control system to ensure uniform vulcanization temperature and pressure, as well as easy operation. The main beam of the vulcanizing machine is made of aviation aluminum alloy (7005-TS) material, which is lightweight, weighing 1/3 less than similar models, but has high strength and is not easily deformed under pressure. Therefore, these vulcanizing machines are reliable in quality and durable. The parts and components used in the DLCBV conveyor belt vulcanizing machine and repair machine produced by Arphu have good versatility and interchangeability, and all electrical control parts and pressure system products are universal. With just one set of vulcanizing equipment, it is possible to repair damage to the conveyor belt such as points, edges, lines, surfaces, and tears, achieving multi-functionality and cost savings for the user. Other machines of the same type do not have this function. These belt vulcanizing machines are made of high-strength aviation aluminum alloy materials and aviation aluminum plates, refined through special processes, and have the characteristics of small volume, light weight, low energy consumption, and rapid heating. After heating, the entire surface of the plate has a certain degree of flexibility and can tightly adhere to the conveyor belt. Under a pressure of 1.5 Mpa, the parallelism of the plate surface is not greater than 0.1mm, exceeding the performance of conventional machines. The heating is uniform at each point on the upper and lower heating plates, and after 0.1 minutes into the insulation stage, the temperature difference at each point on the working surface does not exceed ±3℃, reaching international standards. The time required to heat from room temperature to vulcanization temperature (145℃) does not exceed 25 minutes, and the power is half that of similar models domestically and internationally, resulting in good energy-saving effects. After vulcanization bonding or repair, the joint surface is smooth and smooth, indistinguishable from the original belt, and the adhesion reaches more than 98% of the original belt. The three-in-one structure of the heating layer and insulation layer is simple, making it easy to disassemble and install anytime and anywhere.

In order to meet the automation control requirements of industries such as metallurgy, power, coal, mining, and chemical, the 2 stage belt deviation switch has become an indispensable sensing element. This switch is mainly used to detect the deviation of the conveyor belt and effectively prevent the occurrence of faults such as material overflow caused by belt deviation. The working principle of the 2 stage belt deviation switch is as follows: when the conveyor belt deviates, it will touch the idler on the switch. When the idler deviates to the action angle of level I, the level I switch will be triggered and output an alarm signal. If the conveyor belt continues to deviate, causing the idler to reach the action angle of level II, the level II switch will send a stop signal. By connecting this switch to the control circuit, the automatic shutdown of the conveyor can be achieved. This product has the advantages of easy installation and reliable switch performance, so it has been widely used in conveyor belts. By using the deviation switch, enterprises can improve the safety and stability of the conveyor system, avoid production failures and material losses caused by belt deviation, and improve work efficiency and economic benefits. In order to meet market demand, Suzhou Arphu Industrial Co., Ltd provides various models and specifications of 2 stage belt deviation switches to meet the needs of different industries and application scenarios. We are committed to providing customers with high-quality products and excellent services. Friends from all walks of life are welcome to consult and purchase.

During the maintenance process of conveyor belts, poor quality belt joints can easily lead to delamination and debonding of the joint, ultimately resulting in joint detachment. This not only causes damage to the conveyor belt itself but also poses a great safety hazard to the operating site. Currently, there are various forms of conveyor belt joints, with hot vulcanization joint operation being the most reliable. The guarantee of joint quality lies in the selection of hot vulcanization joint materials. How to choose hot vulcanization joint materials for conveyor belts? Commonly used hot vulcanization joint materials generally include core rubber, bonding surface rubber, and joint paste. The joint paste is mainly used on various adhesive materials and fabric surfaces, primarily for cleaning and activation purposes, enhancing the viscosity between various adhesives in the joint and improving the bonding strength. The core rubber is mainly used in the middle part of the conveyor belt, primarily for bonding and connecting purposes. The quality of the core rubber directly affects the bonding effect. The surface rubber mainly serves as a sealing function and is used at the upper and lower sealing positions. High-quality surface rubber must have tensile strength, wear resistance, and impact resistance. Additionally, depending on the different application scenarios of conveyor belts, the composition of the rubber material also varies. For example, heat-resistant conveyor belts generally use EPDM rubber, and flame-retardant conveyor belts usually incorporate flame-retardant materials into the rubber. Therefore, the hot vulcanization materials for conveyor belts should be selected to be similar in composition to the conveyor belt materials.

After peeling off the first layer, repeat the above steps to peel off the second layer, third layer, etc. 5. After peeling off all layers, use a scraper to clean the peeled rubber layer. 6. Check if the peeled part is completely clean. If there is any remaining rubber layer, the peeling machine can be used again for cleaning. 7. After cleaning, turn off the power supply, remove the fixed steel wire rope, place the peeling machine in the appropriate position, and take dust prevention measures for the next use.

There are three types of electric heating conveyor belt repair vulcanize: 1. DLBRV-I spot repair vulcanizer: used for small area puncture repair of conveyor belt, or repair of belt covering and core damage, can also be used for adhesive repair of cover damage. 2. DLBRV-II edge repair vulcanizer: specifically used for repairing local small area damage of conveyor belt cover, but with low working pressure. 3. DLBRV-III longitudinal tear repair vulcanizer: used for repairing longitudinal scratches and long-term tearing damage of conveyor belt, can also be used for repairing edge damage of the belt. These three types of patches have the characteristics of small size, light weight, convenient installation and removal, uniform temperature, low energy consumption, and high and uniform hydraulic pressure generated by the pressure device. They can be widely used in the repair of rubber belts such as canvas, nylon, and polypropylene, as well as ore and wire rope cores. Installation and use of electric heating conveyor belt repair vulcanizers: (1) Fill the uncured rubber in the repair area. Or have our service personnel install and debug the equipment. (2) Place the lower frame under the repair position (level), and place the water pressure plate under the tape, with the lower heating plate just above the repair position. (3) Place the heating plate, insulation plate, and upper toothed strip on the patch bottom. (4) Install the pull rod, washer, nut, and tighten. (5) Connect the control box and power supply respectively with the primary cable, and connect the heating plate and control box respectively with the secondary cable. (6) Use a high-pressure hose to connect the pump to the water pressure plate, turn on the electronic control box (refer to operation method), and inject water into the water pressure plate to reach the vulcanization pressure. Due to foreign objects in the material or mechanical failures, the belt conveyor will tear along the longitudinal direction for a long time. This patch can effectively and quickly repair the belt. In addition, the factory can produce special repair equipment according to the different needs of users. The belt vulcanizer is an explosion-proof electric heating vulcanizer. It is a lightweight vulcanization equipment specially used for conveyor belt joints. It is an ideal device for canvas, nylon, and wire rope belt joints. The belt vulcanizer has the characteristics of small size, light weight, convenient disassembly and assembly, fast heating, uniform temperature, high thermal efficiency, and safe and reliable operation.

During the process of belt splicing, the most labor-intensive and time-consuming task is the stripping of the conveyor belt joints. Choosing a suitable peeling machine can greatly reduce labor intensity and improve the efficiency of belt splicing. The most important factor in selecting a conveyor belt stripping machine is to determine the type of belt structure. Currently, the most commonly used conveyor belts in China are as follows: 1. Steel cord conveyor belt - also known as "strong belt". The biggest characteristic of this type of conveyor belt is that the steel cords in the belt are arranged longitudinally. 2. Layered belt - also commonly known as "canvas belt" or "EP belt". The basic feature of this type of conveyor belt is that it uses a layered structure of fabric as the core of the belt. 3. Solid core belt - also commonly known as "PVC belt", "PVG belt" or "mining belt". This type of conveyor belt uses a solid structure of fabric as the core of the belt and is widely used in coal mines. For stripping steel cord conveyor belts, our company provides the BPJ-4 strip machine, commonly known as the "steel cord belt strip machine" or "steel cord belt stripper" . For stripping layered belts, our company provides the BPJ-3 strip machine, commonly known as the "rubber belt stripper", "rubber belt strip machine". Currently, manual methods are still used worldwide for stripping solid core belts. The above-mentioned stripping machines developed by our company are suitable for belt widths ranging from 650mm to 2200mm. When selecting a belt stripper machine, users do not need to consider the belt width, they only need to determine the structure of the conveyor belt to determine the model.

Like other tools, the conveyor belt vulcanizing machine may encounter some minor issues during use. These problems can be caused by improper usage or inadequate storage, but they can be resolved immediately without affecting the normal operation of the machine. Common Problem 1: The heating process takes longer or the temperature cannot reach 145℃. If you encounter the above problems, follow these steps to check: (1) Check if a wooden heat insulation plate is placed between the heating plate and the frame. If the insulation plate is not placed or lost, install it before conducting the temperature rise check. (2) If the temperature cannot rise, check if the sulfurization time switch in the upper left corner of the control box is turned on. If it is turned on, the belt vulcanizing machine has entered the insulation stage, and the temperature naturally cannot rise. (3) If the above two conditions are normal but the temperature still cannot rise, check if the insulation board is damp. If the insulation board becomes damp due to water exposure, it needs to be dried with the heating plate before the temperature can reach the required level. (4) If the temperature still cannot rise after the above checks, contact the manufacturer for further technical consultation or return the machine for repair. Common Problem 2: During heating, the temperature of the heating plate is uneven, causing partial joints to fail to bond tightly. Follow these steps to check: (1) Check if the insulation plate is damaged. Damaged insulation board is a major cause of uneven heating temperature. (2) If the insulation board is intact, individually heat the heating plate and use a thermometer to measure the temperature at different parts of the plate. If any issues arise, it is possible that the internal heating element is damaged. Contact the manufacturer for replacement or repair of the heating element. Common Problem 3: When using the manual pump for increasing pressure, the pressure does not increase. Follow these steps to check: (1) Check if the water inlet of the water pressure plate is being pressed due to the tightness of the frame bolts. If this is the case, loosen the bolts slightly. (2) Check if the manual pump has any air leaks or loose connections, and tighten them. Also, check if the gasket of the water pressure pump is damaged. Common Problem 4: Some users may experience the phenomenon of the belt sticking to the heating plate after vulcanization. This issue occurs because users fail to follow the operation requirements and place paper or talcum powder as isolating materials between the upper and lower heating plates. Direct contact between the heating plate and the conveyor belt causes this problem. To resolve this issue, simply clean the heating plate. Strictly follow the operating procedures in the next use to prevent it from happening again. Common Problem 5: Improper storage or accidental impacts during use may cause water leakage in the water pressure plate. Follow these steps to check: (1) Identify the location of the leakage, whether it is on the surface of the water pressure plate or the contact area between the surrounding rubber and the bottom plate of the water pressure plate. If the leakage is from the surrounding gaps, tighten all the surrounding screws in order. (2) If the leakage is on the surface of the rubber of the water pressure plate and appears as needle-like leaks, you can temporarily repair it with adhesive such as 520 glue. However, after the temporary repair, the panel must be replaced. (3) In case of severe leakage, the water pressure plate cannot be used and must be replaced.

The standard operation procedure for conveyor belt vulcanization joint generally includes pre-construction preparation, on-site joint construction process, post-construction documentation, and maintenance. 1. Pre-construction preparation for belt joint: Understand the specifications and performance of the conveyor belt, as well as the on-site construction conditions. It is necessary to be familiar with the specifications, variety, single roll length, and any special requirements for the adhesive joint, as well as the joint position, total length of the conveyor belt, total length of the frame, frame slope, tensioning device situation, number of joints required, whether crane transportation equipment is needed, and the scheduling of the maintenance downtime. Also, consider the construction environment, weather conditions, dust situation, types of dust, and take necessary protective measures. Prepare the required joint tools, such as vulcanizing machine, adhesive materials, clamps, etc. 2. On-site construction process for belt vulcanization joint: Choose a suitable joint position and fix the conveyor belt with clamps. Remove the support frame and install the vulcanizing machine. Align the two ends of the conveyor belt that need to be jointed and mark them with a steel saw blade. Use tools such as a belt peeler to peel the belt, paying attention to the depth of the cut to avoid damaging the fabric layer. Divide the conveyor belt into several uniform-length steps according to the number of layers and peel them off layer by layer, ensuring that the steps at both ends of the joint can match. Use a tungsten steel grinding disc to roughen the surface of the fabric layer and transition area. The purpose of grinding is to remove surface contamination, increase the surface activity and roughness of the adhesive and fabric, and avoid damaging the fabric layer. Clean the joint surface with a blower and wash it with a cleaning agent, then let it dry. Apply adhesive slurry to the surface of the belt joint with a brush. The slurry should be applied evenly, not too much or too little, and generally applied at least two times. When the surface of the belt joint is not sticky, paste the adhesive film and add a 3 cm wide adhesive film at the step position to fill the gap. Peel, grind, and apply adhesive slurry to the other side in the same way, ensuring alignment and making both ends of the belt in a straight line. Then assemble the vulcanizing machine, use a water pump for pressing, and maintain a pressure of about 1.5 MPa until the vulcanization joint is completed. After the vulcanization time is over, wait for the temperature to naturally cool down to 80℃, cut off the power supply, remove the power cable, and release the water pressure before removing the vulcanizing machine. Inspect the overall condition of the joint, check for blistering, lack of adhesive, etc., and trim both sides if necessary. 3. Record the joint situation of the conveyor belt: Record detailed information about the length, angle, time, location, and condition of the joint, as well as the transported materials. Regularly inspect the joint area.

When performing conveyor belt vulcanization, it is important to follow these safety precautions to ensure a safe construction site. ARPHU has compiled a list of safety measures to be taken during conveyor belt joint vulcanization: 1. A dedicated person must monitor the construction site and surrounding areas during the vulcanization process. Any issues discovered on-site should be addressed promptly, and unauthorized personnel should be prohibited from entering the work area. 2. Electrical wiring for the conveyor belt vulcanizing machine must be handled by a professional electrician. Only trained personnel should operate the electrical equipment. 3. During the vulcanization process, workers must strictly follow operating procedures and construction processes to ensure the quality and safety of the joint. 4. When using gasoline for cleaning during the vulcanization process, grinding machines must not be used. When gasoline is not in use, it must be tightly sealed and stored in a safe, shaded area. 5. After the vulcanization joint has completely cooled down and the joint's quality is assured, the vulcanizing machine can be dismantled. 6. Two fire extinguishers should be available at the construction site. 7. No electrical welding work should be conducted within a 10-meter radius of the work area. 8. During the operation, personnel from the mechanical and electrical department should be present on-site to supervise and guide the work. When making conveyor belt joints on-site, it is crucial to remember these safety precautions. If any issues arise during vulcanization, they should be promptly reported and resolved. Always prioritize safety!
