Technical Field
[0001] This utility model relates to the field of reclaimed rubber sheeting machine technology, specifically a sheeting device for reclaimed rubber production. Background Technology
[0002] Reclaimed rubber is rubber that has a certain degree of plasticity and can be reused, processed from vulcanized waste materials in rubber product manufacturing. Depending on the type of waste rubber used, reclaimed rubber is divided into tire tires, inner tubes, rubber shoes, etc. Reclaimed rubber can partially replace raw rubber in rubber products, saving raw rubber and carbon black, and also helps to improve processing performance and certain properties of rubber products. With social development, the application of reclaimed rubber is becoming more and more widespread.
[0003] Existing rubber open mills typically involve manual cutting of the recycled rubber on the pressure rollers. Workers need to stop the roll to cut the rubber, which can affect the production efficiency of recycled rubber sheets. Furthermore, manual cutting introduces significant errors, resulting in uneven cuts and rubber sheets of varying lengths, thus impacting the quality of the final product. Utility Model Content
[0004] The purpose of this invention is to provide a sheeting device for the production of recycled rubber, so as to solve the problem that the existing technology requires manual cutting of rubber, which is labor-intensive and inefficient.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Figure 1 - Figure 5 As shown, this utility model provides a technical solution for a sheeting device for reclaimed rubber production, including a device body 1 and two extrusion rollers 2. The two extrusion rollers are rotatably installed inside the device body 1. A fixing plate 3 is provided inside the device body 1. Mounting plates 4 are fixedly connected to both sides of the fixing plate 3. A circular arc guide rail 10 is fixedly connected to one side of each of the two mounting plates 4. A moving plate 12 is provided on one side of each of the two circular arc guide rails 10. A threaded rod 22 is rotatably installed between the two moving plates 12. A moving block 23 is threadedly connected to the outside of the threaded rod 22. A blade 25 is slidably connected inside the moving block 23.
[0023] Each of the two moving plates 12 has four pulleys 13 rotatably mounted on one side. The eight pulleys 13 are respectively attached to the upper and lower sides of the two arc guide rails 10 and are in rolling connection with the two arc guide rails 10. Each of the two arc guide rails 10 has a limit block 11 fixedly connected to one end. When the rack 15 is meshed with the gear 16, the moving plate 12 moves along the arc guide rail 10 guided by the pulleys 13.
[0024] Both moving plates 12 are slidably connected to one side of a slider 14, and both sliders 14 are fixedly connected to the top of a rack 15. Both ends of the extrusion roller 2 located inside the front of the main body 1 of the device are fixedly connected to gears 16, and the two racks 15 are respectively matched with the two gears 16.
[0025] Each of the two moving plates 12 is fixedly connected to one side with a second electric push rod 17. The output end of each of the two second electric push rods 17 is fixedly connected to a connecting block 18. Each of the two connecting blocks 18 is fixedly connected to one side of its top with a push rod 19. Each of the two push rods 19 is fixedly connected to the outside with a spring 20. The top of each of the two springs 20 is fixedly connected to one of the two sliders 14. Each of the two mounting plates 4 is fixedly connected to one side with a damper 28. The force-bearing end of each of the two dampers 28 is in contact with the two moving plates 12. When the rack 15 and gear 16 are in contact through the spring 20, the rack 15 will not make hard contact with the gear 16, thus reducing wear of the teeth.
[0026] A slide rod 21 is fixedly connected between the two moving plates 12. The slide rod 21 passes through the moving block 23 and is slidably connected to the moving block 23. A second motor 24 is fixedly connected to one side of one of the moving plates 12. The output end of the second motor 24 is fixedly connected to the threaded rod 22. A third electric push rod 26 is fixedly connected to the bottom of the moving block 23. The output end of the third electric push rod 26 is fixedly connected to the blade 25.
[0027] Both mounting plates 4 have their bottom ends penetrating the device body 1 and are slidably connected to it. Two fixing blocks 7 are slidably connected to the top of the fixing plate 3. Circular blades 8 are rotatably mounted on the top of each of the two fixing blocks 7. A bidirectional threaded rod 5 is rotatably connected between the two mounting plates 4. The two fixing blocks 7 are threaded to both ends of the bidirectional threaded rod 5. A first motor 6 is fixedly connected to one side of one of the mounting plates 4. The output end of the first motor 6 is fixedly connected to the bidirectional threaded rod 5. The distance between the two circular blades 8 is adjusted by rotating the bidirectional threaded rod 5, thereby adjusting the width of the rubber sheet.
[0028] The bottom of the device body 1 is fixedly connected to a first electric push rod 9. The output end of the first electric push rod 9 is fixedly connected to a fixed plate 3. A guide rod 27 is rotatably installed on the front side of the device body 1.
[0029] In use, the extrusion roller 2 rotates, causing the recycled rubber to wrap around the outside of the extrusion roller 2 at the front of the main body 1. The working method of the extrusion roller 2 is a mature existing technology, so it will not be described in detail here. Before slicing the rubber pressed on the outside of the extrusion roller 2, the first electric push rod 9 drives the two mounting plates 4 upward through the fixing plate 3. At this time, the mounting plate 4 drives the fixing block 7 upward, so that the two circular blades 8 come into contact with the extrusion roller 2 and cut the rubber. The two fixing blocks 7 are threaded to both ends of the bidirectional threaded rod 5. Before slicing the rubber, the first motor 6 can drive the bidirectional threaded rod 5 to rotate, so that the two fixing blocks 7 move closer or further apart, thereby adjusting the width of the cut rubber slice. During adjustment, the second motor 24 drives the threaded rod 22 to rotate, thereby adjusting the initial position of the blade 25 so that the blade 25 is located outside one of the fixing blocks 7.
[0030] When slicing the rubber, the second electric push rod 17 is activated. The second electric push rod 17, through the connecting block 18, drives the push rod 19 upwards. The push rod 19, via the spring 20, pushes the slider 14 to move, thereby causing the slider 14 to push the rack 15 towards the gear 16. When the circular cutter 8 contacts the extrusion roller 2, the center of the arc surface of the arc guide rail 10 is the same as that of the gear 16. When the rack 15 and gear 16 are in contact and meshing, the gear 16, through the rack 15, drives the moving plate 12 to move outside the arc guide rail 10. Simultaneously, the third electric push rod 26 operates, causing the blade 25 to move towards the extrusion roller 2 and come into contact with it. Through the gear 16, the blade 25 between the two moving plates 12 rotates with the extrusion roller 2 while remaining in contact with it. At this time, the second motor 24 operates, driving the threaded rod 22 to rotate, causing the blade 25 to move from the outside of one fixed block 7 to the outside of the other fixed block 7, thereby performing a sliding cut on the rubber on the opposite side of the two fixed blocks 7. This is achieved through the rack 15... The moving blade 25 rotates with the extrusion roller 2, allowing the device to cut recycled rubber without stopping, thus improving production efficiency. When the blade 25 moves to the outside of another fixed block 7, the third electric push rod 26 and the second electric push rod 17 work simultaneously to move the blade 25 and the rack 15 away from the extrusion roller 2 and the gear 16, respectively. Under the action of gravity, the moving plate 12 moves along the arc guide rail 10 towards the damper 28 and re-fits with the damper 28. At this time, the worker can guide the rubber sheet cut outside the extrusion roller 2 to the top of the guide rod 27 for collection. When the rubber sheet reaches the required length, the blade 25 repeats the previous work to cut the rubber sheet, thus completing the sheet output. The second motor 24 drives the blade 25 to cut the rubber without manual cutting, ensuring the consistency of the rubber sheet cut and improving product quality. At the same time, by controlling the operation of the second electric push rod 17, the blade 25 can automatically cut the rubber sheet according to the stroke of the extrusion roller 2, so that the produced rubber sheets are of the same length, thereby improving the output quality of the rubber sheet.
