Abstract
Description
Technical Field
[0001] The utility model relates to the field of conveyor belt processing, in particular to a hot pressing device for conveyor belt production. Background Art
[0002] Conveyor belt processing involves the process of converting raw materials into conveyor belts of varying specifications and types for use in industrial production and logistics transportation systems. Conveyor belts are made from a variety of materials, including environmentally friendly, cold- and heat-resistant polyurethane conveyor belts, which combine the advantages of polyurethane. Designed for extreme temperature environments, they withstand both low and high temperatures, making them suitable for a variety of extreme working conditions. The mixed polyurethane material is then hot-pressed to create the basic shape of the conveyor belt. However, traditional hot-pressing equipment can easily cause the conveyor belt sheet to shift due to pressure, affecting the quality of the hot-pressed sheet.
[0003] After searching, the Chinese patent "A conveyor belt hot press with temperature control device" authorization announcement number is "CN212858165U". After the power is turned on, the external machine equipment transports the plate to the middle of the two side plates through the end of the clamping plate with an inclined surface. During transportation, the end corners of the plate contact the inclined surfaces of the ends of the two clamping plates. The plate will squeeze the inclined surfaces of the ends of the clamping plates, so that the two clamping plates drive the guide rods to shrink toward the inside of the side plates and compress the clamping springs until the plate is completely located in the middle of the two clamping plates. At this time, the clamping springs apply a reverse force to the clamping plates through the guide rods, so that the two clamping plates clamp and fix the plate, and because the guide rods can shrink toward the inside of the side plates, the clamping plates can clamp and fix plates of different sizes.
[0004] Although the plate is clamped and fixed by the clamping spring and the guide rod, when the spring forms a reaction force, the larger the plate is, the greater the pressure exerted by the clamping plate on both sides of the plate. Excessive clamping force can easily lead to local deformation of the plate, and when the plate is pushed between the two clamping plates, there will be a certain amount of friction between the two sides of the plate and the side opposite to the two clamping plates, which can easily cause wear on both sides of the plate, increasing production costs and reducing production accuracy.
[0005] Therefore, a hot pressing device for producing a conveyor belt is proposed to solve the above problems. Utility Model Content
[0006] The purpose of the present invention is to provide a hot pressing device for conveyor belt production in order to solve the above problems, thereby improving the problem that excessive clamping force during the positioning and processing of the plate can easily lead to local deformation of the plate and cause wear on both sides of the plate.

Through the air storage cylinder, the first piston, the extrusion rod, the electric telescopic rod, the air guide tube, the air collection cylinder, the force rod and the second piston, it is achieved by placing the conveyor belt plate on the hot pressing table between the two clamping plates, and pushing the extrusion rod and the first piston through the electric telescopic rod. The first piston transports the air in the air storage cylinder to the air collection cylinder through the air guide tube, and then the gas pushes the second piston and the force rod, and the force rod pushes the clamping plates to the two sides of the plate to clamp and limit the plate. This limiting method can avoid excessive clamping of the two sides of the plate, prevent the plate from deformation, and avoid friction between the two sides of the plate and the two sides of the clamping plate, which causes wear on both sides of the plate.
[0008] Preferably, positioning blocks are fixedly connected to both sides of the gas cylinder, and the tops of the positioning blocks are fixedly connected to the inner top of the hot pressing platform. The positioning blocks are used to fix the gas cylinder.
[0009] Preferably, a limit ring is fixedly connected to the inner wall of the air reservoir, and the limit ring is located on one side of the air inlet end of the air duct. The limit ring limits the first piston and prevents the first piston from moving to the air outlet end of the air duct.

Through the air storage cylinder, the first piston, the extrusion rod, the electric telescopic rod, the air guide tube, the air collection cylinder, the force rod, and the second piston, the conveyor belt plate is placed on the hot press table between the two clamping plates. The electric telescopic rod pushes the extrusion rod and the first piston. The first piston transports the air in the air storage cylinder to the air collection cylinder through the air guide tube. Then the gas pushes the second piston and the force rod. The force rod pushes the clamping plates to the two sides of the plate to clamp and limit the plate. This limiting method avoids the problem that conventional limiting methods easily generate excessive clamping force on both sides of the plate, causing deformation of the plate and friction between the two sides of the plate and the two sides of the clamping plates, causing wear on both sides of the plate.
[0019] 2. Through the pressure sensor, when the splint clamps the two sides of the plate, the pressure sensor will receive the clamping force of the splint on the plate. When the pressure value on the control panel reaches the appropriate range, the movement of the splint can be stopped. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the force-bearing rod 707 located in the inner cavity of the air collecting cylinder 706 is fixedly connected to the second piston 708, and the other end of the force-bearing rod 707 is fixedly connected to a connecting ring 709. One side of the connecting ring 709 is fixedly connected to one side of the splint 3. Both sides of the air storage cylinder 701 are fixedly connected to positioning blocks 710. The top of the positioning block 710 is fixed to the inner top of the hot pressing table 1. Fixed connection, the inner wall of the air storage cylinder 701 is fixedly connected with a limit ring 711, the limit ring 711 is located on one side of the air inlet end of the air guide tube 705, the air inlet end and the air outlet end of the air guide tube 705 are fixedly connected with a sealing ring 712, the two sealing rings 712 are respectively fixedly connected to one side of the air storage cylinder 701 and the air collecting cylinder 706, the outer surface of the electric telescopic rod 704 is fixedly connected with a positioning ring 713, and one end of the positioning ring 713 is fixedly connected to one side of the inner wall of the hot pressing platform 1.
[0027] like Figure 2 and Figure 3 As shown, the driving mechanism 5 includes a motor 501 fixedly connected to one side of the inner wall of the splint 3, the output end of the motor 501 is fixedly connected to the driving rod 502, one end of the driving rod 502 is fixedly connected to the first gear 503, one side of the first gear 503 is meshed with the second gear 504, the inner wall of the second gear 504 is fixedly connected to the bidirectional screw rod 505, and both ends of the bidirectional screw rod 505 are rotatably connected to the inner wall of the splint 3.

While the splint 3 clamps the two sides of the plate, the pressure sensor 4 will receive the clamping force of the splint 3 on the plate. When the pressure value on the control panel 10 reaches the appropriate range, the movement of the splint 3 can be stopped. This limiting method can avoid excessive clamping of the two sides of the plate, prevent the plate from deformation, and avoid friction between the two sides of the plate and the two sides of the splint 3, which causes wear on both sides of the plate.
