Description

Technical Field

[0001] This utility model relates to the field of scrap recycling, and in particular to a scrap recycling device for release paper processing. Background Technology

[0002] Release paper, also known as silicone paper or anti-stick paper, is a specially treated paper with a surface coated with an anti-sticking substance (such as silicone oil, polyethylene, or polytetrafluoroethylene), giving it anti-adhesive properties. This treatment allows release paper to easily separate from adhesive substances (such as tape, labels, and glue) without leaving residue. The processing of release paper generates scraps, which can be recycled, improving resource utilization and the production environment.

[0003] Traditional release paper scrap recycling devices may rely on manual collection of scraps, which leads to low production efficiency and cannot meet the needs of high-speed production lines. Furthermore, the shredded scraps are mixed together without being sorted by size, making it difficult to reprocess large pieces of scraps and potentially resulting in inconsistent quality of the final recycled materials.

[0004] Therefore, there is a particular need for a waste recycling device for release paper processing to solve the above problems. Utility Model Content

[0029] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0030] Example: A waste recycling device for release paper processing, see reference. Figures 1-9 As shown, the device includes a frame 1, a first conveyor roller 2, a first conveyor belt 3, a first motor 4, a crushing component, and a moving component. The two first conveyor rollers 2 are distributed on the left and right sides and are rotatably connected to the upper part of the frame 1. The first conveyor belt 3 is rotatably connected between the two first conveyor rollers 2. The first motor 4 is bolted to the upper right front side of the frame 1, and its output shaft is fixedly connected to the front end of the right first conveyor roller 2. The crushing component is located on the right side of the frame 1, and the moving component is located on the lower part of the frame 1. The device also includes a screening mechanism, which is located between the frame 1 and the crushing component.

[0031] See Figures 1-3 and Figure 5 As shown, the crushing assembly includes a crushing box 5, a second motor 6, a guide plate 7, crushing rollers 8, gears 9, and a first guide frame 17. The crushing box 5 is welded to the right side of the frame 1. The first discharge port 501 is located on the lower right side of the crushing box 5. The second motor 6 is bolted to the upper left side of the crushing box 5. The guide plate 7 is welded to the upper part of the crushing box 5. Two crushing rollers 8 are distributed on the left and right sides and are rotatably connected to the inside of the crushing box 5. The output shaft of the second motor 6 is fixedly connected to the front end of the left crushing roller 8. The rightmost edge of the guide plate 7 is aligned between the upper sides of the two crushing rollers 8 and is designed to be inclined. The inclined surface extends from the upper left to the lower right, which can accurately guide the scrap material between the two crushing rollers 8. The gears 9 are welded to the rear end of the crushing rollers 8 that protrude to the outside of the crushing box 5. The two gears 9 are of equal thickness and mesh with each other. The first guide frame 17 is welded to the lower right side of the crushing box 5 and is located below the right side of the first discharge port 501.

[0032] See Figure 1 , Figure 7 and Figure 9As shown, the moving component includes a push handle 101, an electric slide rail 27, an electric slider 28, and a roller 29. The push handle 101 is connected to the upper left side of the frame 1 by welding to facilitate pushing the frame 1. Multiple electric slide rails 27 are arranged along a rectangular direction and are connected to the lower part of the frame 1 by bolts. The electric slider 28 is slidably connected to the inside of the electric slide rail 27, and the roller 29 is rotatably connected to the side of the electric slide rail 27 away from the frame 1.

[0033] See Figures 1-6 As shown, the screening mechanism includes a convex plate 10, a screen 11, a connecting rod 12, a folding belt 13, a fixing block 14, a guide rod 15, a first spring 16, and a conveying assembly. The convex plate 10 is connected to the output shaft of the second motor 6 by a key connection. The screen 11 is slidably connected inside the crushing box 5 and located below the crushing roller 8. The connecting rod 12 is welded to the middle of the front side of the screen 11 and is slidably connected to the crushing box 5. The convex plate 10 is located above the connecting rod 12 and has the same thickness as it, so that when the convex plate 10 presses the connecting rod 12, a tight and stable contact surface can be formed between the two. The folding belt 13 is bonded between the lower end of the connecting rod 12 and the lower part of the crushing box 5. When the connecting rod 12 moves, it can dynamically block the slot on the crushing box 5 for the connecting rod 12 to move, preventing foreign objects from getting stuck in the slot and affecting the movement of the connecting rod 12. Multiple fixing blocks 14 are arranged along a rectangular direction and are welded to the four corners of the lower part of the crushing box 5. Multiple guide rods 15 are arranged in a U-shape and connected to the four corners of the bottom of the screen 11 by welding. They are slidably connected to the vertically aligned fixing blocks 14. The two guide rods 15 on the right are longer than the two guide rods 15 on the left, and the length of the two guide rods 15 on the left is sufficient for the screen 11 to move downwards, but shorter than the distance between the bottom right side of the screen 11 and the top surface of the first discharge port 501. This ensures that the bottom right side of the screen 11 does not exceed the top surface of the first discharge port 501. The first spring... 16 is fitted outside the guide rod 15, and its two ends are fixedly connected to the fixing block 14 and the screen 11 respectively. The second discharge port 18 is opened on the lower left side of the crushing box 5. The top surface of the left side of the screen 11 is on the same horizontal plane as the top surface of the second discharge port 18. The lower ends of multiple guide rods 15 are provided with round blocks larger than their diameter. The top surface of the round blocks contacts the bottom surface of the fixing block 14, so that the guide rods 15 are limited and can only move downward, ensuring that the top surface of the left side of the screen 11 is always aligned with the top surface of the second discharge port 18.

[0034] See Figure 1 and Figure 6As shown, the conveying assembly includes a second conveyor roller 19, a second conveyor belt 20, a pulley assembly 21, a second guide frame 22, and a baffle plate 23. The two second conveyor rollers 19 are distributed left and right and rotatably connected to the lower part of the frame 1. The second conveyor belt 20 is rotatably connected between the two second conveyor rollers 19. The pulley assembly 21 is located between the front end of the left first conveyor roller 2 and the left second conveyor roller 19. The second guide frame 22 is connected to the lower left side of the frame 1 by welding and is located below the left side of the second conveyor belt 20 and contacts it. The two baffle plates 23 are distributed front and back and are connected to the lower part of the frame 1 by welding. The right end contacts the second discharge port 18, and the bottom surface contacts the top surface of the second conveyor belt 20.

[0035] See Figures 7-8 As shown, it also includes a cleaning mechanism, which is located on the upper right side of the frame 1. The cleaning mechanism includes a sleeve 24, a scraper 25, and a second spring 26. The sleeve 24 is connected to the upper right side of the frame 1 by welding, and the right side is embedded in the left side of the crushing box 5. The scraper 25 is slidably connected inside the sleeve 24, and its upper part is in contact with the right side of the first conveyor belt 3. Multiple second springs 26 are arranged in a straight line with longitudinal spacing, and their two ends are fixedly connected to the sleeve 24 and the scraper 25 respectively.

[0036] When this device is needed, first activate the electric slide rail 27 to control the electric slider 28 to move downwards until the roller 29 contacts the ground, suspending the frame 1. Then, hold the push handle 101 and push the frame 1 under the release paper processing equipment, so that the first conveyor belt 3 is directly below the cutting structure of the release paper processing equipment. Next, control the electric slider 28 to move upwards until the roller 29 leaves the ground, placing the frame 1 stably. Then, place the two pre-prepared receiving frames on the left and right sides of the frame 1, with the left receiving frame directly below the second guide frame 22 and the right receiving frame directly below the first guide frame 17. When the scrap material cut by the cutting structure of the release paper processing equipment falls onto the first conveyor belt 3, start the first motor 4 and the second motor 6. The output shaft of the motor 6 drives the left first conveyor roller 2 to rotate, making it work in conjunction with the right first conveyor roller 2 to pull the first conveyor belt 3 to rotate and convey the scrap material to the right. During the conveying process, the scraper 25, under the action of the second spring 26, continuously contacts the surface of the first conveyor belt 3, scraping off the fine impurities on its surface and keeping the surface of the first conveyor belt 3 clean. The conveyed scrap material falls into the crushing box 5 and falls along the guide plate 7 between the two crushing rollers 8. At this time, the output shaft of the second motor 6 drives the left crushing roller 8 to rotate clockwise, and the left crushing roller 8 drives the left gear 9 to rotate clockwise, meshing with the right gear 9, so that the right gear 9 drives the right crushing roller 8 to rotate counterclockwise synchronously, crushing the scrap material. The crushed scrap material falls onto the screen 11 for screening. During screening, small pieces of scrap material pass through the screen 11 and fall into the lower part of the crushing box 5, exiting from the first discharge port 501 and being guided by the first guide frame 17 into the right-side receiving frame. Larger pieces of scrap material remain on the screen 11 and gradually accumulate, exiting from the second discharge port 18 onto the second conveyor belt 20. During screening, the output shaft of the second motor 6 simultaneously drives the convex plate 10 to rotate clockwise, intermittently squeezing the connecting rod 12. This causes the connecting rod 12 to move the screen 11 downwards, compressing the first spring 16. When the convex plate 10 continues to rotate clockwise without squeezing the connecting rod 12, the first spring 16 returns to its original state, causing the screen 11 to move upwards and reset. This process repeats, continuously moving the screen 11 downwards and upwards, accelerating the screening speed of the scrap material. When rod 12 moves downwards or upwards, it compresses or stretches folded belt 13, ensuring that folded belt 13 always blocks the slot on crushing box 5. When large pieces of scrap material fall onto the second conveyor belt 20, the left first conveyor roller 2 drives the left second conveyor roller 19 to rotate via pulley assembly 21, causing it to work in conjunction with the right second conveyor roller 19, driving the second conveyor belt 20 to rotate and convey the large pieces of scrap material to the left. The large pieces of scrap material are then discharged from the second guide frame 22 and fall into the left receiving frame. During the conveying process, baffle plate 23 blocks the large pieces of scrap material on the second conveyor belt 20, preventing them from falling off the front and rear sides of the second conveyor belt 20. When the left receiving frame is full of large pieces of scrap material, the receiving frame is replaced, and the collected large pieces of scrap material are poured onto the first conveyor belt 3 for secondary crushing.After being crushed into small pieces, the scraps can be poured into a compressor for compression.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
