[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-6 An EPDM strip unwinding and polishing device includes a support plate 1, a limiting block 2 fixedly connected to the lower outer side of the support plate 1, a through groove 3 opened on one side of the inner side of the limiting block 2, limiting plates 4 slidably connected to both sides of the inner side of the limiting block 2, a sliding plate 6 provided inside the limiting block 2 and located between the two limiting plates 4, rollers 7 symmetrically rotatably connected to both sides of the outer side of the sliding plate 6, a limiting roller 8 provided outside the support plate 1 and above the limiting block 2, a polishing roller 9 provided outside the support plate 1 and above the limiting roller 8, a take-up roller 10 provided outside the support plate 1 and above the polishing roller 9, and a transmission assembly provided outside the limiting block 2.

[0025] Specifically, the transmission assembly includes a first motor 11 and a linkage unit. The first motor 11 is fixedly connected to the outer side of the limiting block 2 via a mounting bracket. A rotating block 12 is fixedly connected to the outer side of the output end of the first motor 11. Connecting rods 13 are rotatably connected to both outer sides of the rotating block 12. Slide rods 14 are rotatably connected to the inner side of the two connecting rods 13 away from the rotating block 12. The slide rods 14 are slidably connected to the inside of the limiting block 2. Two limiting plates 4 are fixedly connected to one end of the corresponding slide rods 14. The slide plate 6 can move through the linkage unit. The linkage unit includes a first lead screw 15. The first lead screw 15 is fixedly connected to one end of the output end of the first motor 11 extending into the inside of the limiting block 2. The slide plate 6 is threadedly connected to the outside of the first lead screw 15. Limiting rods 5 are fixedly connected to the inside of the limiting block 2 and to both sides of the first lead screw 15. The slide plate 6 is slidably connected to the outside of the limiting rods 5.

[0026] The above technical solution involves first installing the adhesive strip roll onto the unwinding reel 28, then passing the adhesive strip through the through groove 3 in the limiting block 2, then through the outside of the limiting roller 8, then through the inside of the grinding roller 9, and finally winding it around the outside of the take-up roller 10. An external controller starts the first motor 11, whose output drives the rotating block 12 to rotate. This causes the rotating block 12 to slide inward via the connecting rods 13 on both sides, which in turn drives the corresponding sliding rod 14 to slide inward via the sliding rod 14, until the limiting plate 4 is fully positioned on both sides of the adhesive strip, thus preventing the adhesive strip from being damaged in subsequent processes. Misalignment during the grinding process affects the grinding effect. Simultaneously, the first motor 11 drives the first lead screw 15 to rotate, causing the lead screw 15, through its threaded connection, to move the slide plate 6 towards the rubber strip under the control of the limit rod 5, until it drives the two sets of rollers 7 to press the rubber strip firmly. This effectively prevents the rubber strip from shaking during subsequent grinding, ensuring that the rubber strip and grinding roller 9 remain parallel, thus improving the grinding effect. After the rubber strip is controlled by the limit plate 4 and rollers 7, the turntable 26 rotates, driving the second lead screw 25 to rotate, allowing the second lead screw 25 to pass through... The threaded connection causes the sliding frame 23 to move towards the second limit seat 27 under the limit of the first limit seat 22. This, in turn, drives the second motor 19 and the grinding roller 9 towards the second limit seat 27 until the grinding roller 9 pushes the rubber strip into contact with the second limit seat 27, thus limiting the rubber strip between the second limit seat 27 and the grinding roller 9. Then, the bolt 24 is tightened, fixing the sliding frame 23 and the grinding roller 9 in their current position. Finally, the second motor 19 and the third motor 21 are started via an external controller. The output of the second motor 19 drives the grinding roller 9 to rotate at high speed. The output of the third motor 21 can drive the take-up roller 10 to rotate, thereby taking up the rubber strip. This allows for continuous grinding of the rubber strip in conjunction with the unwinding reel. It also facilitates the collection of the rubber strip by the staff after grinding. The device can limit the rubber strip through the limiting plate 4 and roller 7 inside the limiting block 2. This not only prevents the rubber strip from shifting during subsequent grinding, which would affect the grinding effect, but also presses the rubber strip tightly, so that the rubber strip and the grinding roller 9 always remain parallel, avoiding shaking of the rubber strip during subsequent grinding, thereby improving the grinding effect.

[0027] Specifically, a limiting post 16 is fixedly connected to the outside of the support plate 1 and on both sides of the limiting roller 8. A sliding post 17 is slidably connected inside the two limiting posts 16. A spring 18 is provided inside the limiting post 16 and on one side of the sliding post 17. The limiting roller 8 is rotatably connected between the two sliding posts 17.

[0028] Through the above technical solution, the elastic force of the spring 18 set inside the limiting post 16 can drive the limiting roller 8 to push the rubber strip continuously, thereby tightening the rubber strip and making the rubber strip and the grinding roller 9 fit more closely, thereby further improving the grinding effect.

[0029] Specifically, a first limiting seat 22 is fixedly connected to the outer side of the support plate 1 and above the limiting roller 8. A sliding frame 23 is slidably connected to the top side of the first limiting seat 22. A second motor 19 is fixedly connected inside the sliding frame 23. The grinding roller 9 is fixedly connected to the output end of the second motor 19. A second lead screw 25 is rotatably connected to the outer side of the support plate 1 and above the first limiting seat 22. The sliding frame 23 is threaded to the outside of the second lead screw 25. A turntable 26 is fixedly connected to one end of the second lead screw 25. A bolt 24 is threaded to the outer side of the sliding frame 23. The bolt 24 is connected to the first limiting seat 8. The inner wall of the seat 22 is slidably connected. The second limit seat 27 is fixedly connected to the outer side of the support plate 1 near the first limit seat 22. Fixing plates 20 are fixedly connected to the outer side of the support plate 1 and on both sides of the take-up roller 10. The take-up roller 10 is rotatably connected between the two fixing plates 20. The outer side of the fixing plate 20 is fixedly connected to the third motor 21 through the mounting plate. The output end of the third motor 21 extends to the inner side of the fixing plate 20 and is fixedly connected to the take-up roller 10. The first motor 11, the second motor 19 and the third motor 21 are all electrically connected to the external controller. The unwinding reel 28 is rotatably connected to the top side of the support plate 1.

[0030] Through the above technical solution, the first motor 11, the second motor 19 and the third motor 21 can be quickly controlled by the staff through the external controller.

[0031] In use, first, the rubber strip roll is installed on the unwinding reel 28. The rubber strip is then passed through the through groove 3 in the limiting block 2, then through the outside of the limiting roller 8, then through the inside of the grinding roller 9, and finally wound around the outside of the take-up roller 10. The first motor 11 is started by the external controller. The output end of the first motor 11 drives the rotating block 12 to rotate, so that the rotating block 12 drives the corresponding sliding rod 14 to slide inward through the connecting rods 13 on both sides. In turn, the sliding rod 14 drives the corresponding limiting plate 4 to slide inward until the two sides of the rubber strip are limited. This prevents the rubber strip from shifting during the subsequent grinding process, which would affect the grinding effect. And while the first motor 11 is running... The first lead screw 15 can be driven to rotate, so that the first lead screw 15 drives the slide plate 6 to move towards the rubber strip under the limit of the limit rod 5, until it drives the two sets of rollers 7 to press the rubber strip tightly. This can effectively prevent the rubber strip from shaking during subsequent grinding and ensure that the rubber strip and the grinding roller 9 always remain parallel, improving the grinding effect. After the rubber strip is limited by the limit plate 4 and the rollers 7, the turntable 26 is rotated to drive the second lead screw 25 to rotate, so that the second lead screw 25 drives the sliding frame 23 to move towards the second limit seat 27 under the limit of the first limit seat 22, thereby driving the second motor 19 and the grinding roller 9 to move towards the limit through the sliding frame 23. The second limiting seat 27 moves until the grinding roller 9 pushes the rubber strip into contact with the second limiting seat 27, so that the rubber strip is limited between the second limiting seat 27 and the grinding roller 9. Then, the bolt 24 is tightened, so that the sliding frame 23 drives the grinding roller 9 to fix in the current position. Then, the second motor 19 and the third motor 21 are started by the external controller. The output end of the second motor 19 can drive the grinding roller 9 to rotate at high speed, thereby grinding the rubber strip. The output end of the third motor 21 can drive the take-up roller 10 to rotate, thereby taking up the rubber strip. This can be used in conjunction with the unwinding reel to continuously grind the rubber strip, and at the same time, it is convenient for the staff to collect the rubber strip after grinding. This device can be limited by the limiting seat 27. The limiting plate 4 and roller 7 inside block 2 limit the rubber strip, which not only prevents the rubber strip from shifting during subsequent grinding and affecting the grinding effect, but also presses the rubber strip tightly, so that the rubber strip and the grinding roller 9 always remain parallel, avoiding the rubber strip from shaking during subsequent grinding, thereby improving the grinding effect. The elastic force of the spring 18 set inside the limiting column 16 can drive the limiting roller 8 to push the rubber strip, thereby tightening the rubber strip and making the rubber strip and the grinding roller 9 more closely fit, thereby further improving the grinding effect. The first motor 11, the second motor 19 and the third motor 21 can be quickly controlled by the operator through the external controller.
