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.
