Technical Field
[0001] This utility model relates to the technical field of edge grinding devices, and in particular to an edge grinding device for plastic packaging products. Background Technology
[0002] Plastic packaging refers to various packaging products made from plastic as raw material. Due to its advantages such as lightness, low cost, and diverse performance, plastic packaging is used in food, medicine, daily chemical and other fields. The packaging produced includes lunch boxes, mineral water bottles, building material packaging and pharmaceutical packaging. Through continuous technological innovation, biodegradable plastic packaging is now being promoted for the purpose of recycling.
[0003] A search revealed a Chinese patent with patent number CN217572231U, titled "A Grinding Device for the Edges of Plastic Packaging Products." The patent's design includes a grinding device body; an inclined frame is inserted and connected to one side of the top of the grinding device body; a cleaning box is fixedly installed on the top of the grinding device body; baffles are inserted and connected to both sides of the top of the cleaning box; a motor base is fixedly installed on one side of the bottom of the cleaning box; a motor is fixedly installed on the top of the motor base; two rotating columns are inserted and connected to the bottom of the cleaning box; the bottom of one of the rotating columns is connected to the output shaft of the motor; the two rotating columns are connected by a conveyor belt; and cleaning rollers are provided at the top of each of the two rotating columns. The solution addresses the issue mentioned in the background technology that "after the edges of plastic products are polished using a polishing device, a lot of debris remains on the surface. Most polishing devices cannot remove the debris in time, resulting in an unattractive product. Some polishing devices can remove the debris in time, but the product is prone to displacement during transportation to the cleaning location, increasing labor costs and reducing the efficiency of the polishing device." However, in actual use, it was found that the distance between the two cleaning rollers could not be adjusted according to the actual situation. Therefore, it could only clean plastic packaging of the same width and it was difficult to clean plastic packaging of other different specifications, which greatly reduced the applicability of the entire polishing device.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0023] refer to Figure 1-4In this embodiment, the system includes a cleaning box 1, a positioning cleaning roller 2, and a movable cleaning roller 3. A hanging plate 4 is provided at the bottom of the cleaning box 1. A spacing control component 5 is provided on the side of the hanging plate 4 below the cleaning box 1, used to control and adjust the telescopic component 6. The spacing control component 5 includes a spacing adjustment motor 11, a spacing drive wheel 12, a transmission wheel 13, a fixed seat 14, an adjusting screw 15, and a movable sleeve 16. The spacing adjustment motor 11 is fixedly connected to the side of the hanging plate 4, the spacing drive wheel 12 is fixedly connected to the output shaft of the spacing adjustment motor 11, the fixed seat 14 is fixedly connected to the side of the hanging plate 4, and the adjusting screw 15... Rod 15 is rotatably connected to fixed base 14. One end of adjusting screw 15 is fixedly connected to the surface of transmission wheel 13. Transmission wheel 13 and spacing drive wheel 12 mesh with each other. Movable sleeve 16 is threaded onto the surface of adjusting screw 15. During operation, positioning cleaning roller 2 and movable cleaning roller 3 need to be stopped, and then spacing adjusting motor 11 is started. Starting spacing adjusting motor 11 will drive spacing drive wheel 12 to rotate. The rotation of spacing drive wheel 12 will drive transmission wheel 13 to rotate. The rotation of transmission wheel 13 will drive adjusting screw 15 on fixed base 14 to rotate. The rotation of adjusting screw 15 will drive movable sleeve 16 to move along adjusting screw 15.
[0024] The spacing control component 5 is equipped with a telescopic component 6, which includes a driving ring 17, a positioning rod 18, a positioning end 19, and an adjusting sleeve 20. The positioning end 19 is fixedly connected to the end face of the positioning rod 18. The adjusting sleeve 20 is movably sleeved on the surfaces of the positioning end 19 and the positioning rod 18. The driving ring 17 is rotatably sleeved on the surface of the adjusting sleeve 20 and is fixedly connected to the end face of the movable sleeve block 16. The positioning end 19 is hexagonal prism-shaped, and the inner wall shape of the adjusting sleeve 20 is similar to... The shapes of the positioning ends 19 are matched, so the adjusting sleeve 20 can only move along the positioning rod 18 and the positioning end 19 on the surface of the positioning end 19 and the positioning rod 18, and cannot rotate on its own, which improves the stability of the adjusting sleeve 20. Thus, the rotation of the positioning rod 18 will stably drive the adjusting sleeve 20 to rotate through the positioning end 19. During operation, when the adjusting sleeve block moves, it will drive the driving ring 17 to move, and the movement of the driving ring 17 will drive the adjusting sleeve 20 to move along the positioning end 19.
[0025] The bottom of the cleaning box 1 is rotatably connected to a positioning transmission assembly 7, which includes a first positioning bevel gear 21, a second positioning bevel gear 22, a drive motor 23, a third positioning bevel gear 24, and a positioning frame 25. The drive motor 23 is fixedly connected to the side of the hanging plate 4. The first positioning bevel gear 21 is rotatably connected to the bottom of the cleaning box 1, and its top end extends into the interior of the cleaning box 1 and is fixedly connected to the bottom end of the positioning cleaning roller 2. The second positioning bevel gear 22 is fixedly connected to the output shaft end of the drive motor 23, and meshes with the first positioning bevel gear 21. The positioning frame 25 is movably sleeved on the surfaces of the first positioning bevel gear 21 and the third positioning bevel gear 24, and the third positioning bevel gear 24 meshes with the first positioning bevel gear 21. The third positioning bevel gear 24 is fixedly connected to the end face of the positioning rod 18, and the positioning frame 25 is fixedly connected to the bottom of the cleaning box 1. During operation, after the distance between the positioning cleaning roller 2 and the movable cleaning roller 3 is adjusted, the drive motor 23 is started. The start of the drive motor 23 will drive the second positioning bevel gear 22 to rotate. The rotation of the second positioning bevel gear 22 will drive the first positioning bevel gear 21 to rotate. The rotation of the first positioning bevel gear 21 will drive the positioning cleaning roller 2 to rotate. The rotation of the first positioning bevel gear 21 will synchronously drive the third positioning bevel gear 24 to rotate. The rotation of the third positioning bevel gear 24 will drive the movable transmission component 10 to rotate through the telescopic component 6. The rotation of the movable transmission component 10 will drive the movable cleaning roller 3 at that position to rotate, thereby realizing the synchronous rotation of the positioning cleaning roller 2 and the movable cleaning roller 3.
[0026] The top end of the positioning transmission assembly 7 extends into the interior of the cleaning box 1 and is fixedly connected to the bottom end of the positioning cleaning roller 2. A movable through groove 8 is provided at the bottom of the cleaning box 1. A movable shielding assembly 9 is provided at the position corresponding to the movable through groove 8 on the bottom of the inner wall of the cleaning box 1. The movable shielding assembly 9 includes a shielding plate 30, which is movably connected to the position corresponding to the movable through groove 8 on the bottom of the inner wall of the cleaning box 1. The shielding plate 30 is movably sleeved on the connecting shaft of the first movable bevel gear 26. The bottom of the shielding plate 30 is fixedly connected to the top end of the movable frame 28, providing shielding. The length of the plate 30 is twice the length of the movable through slot 8, and the width of the baffle plate 30 is greater than the width of the movable through slot 8. During operation, the baffle plate 30 will move according to the movement of the movable transmission component 10. The movable transmission component 10 moves along the movable through slot 8 inside the movable through slot 8. Thus, the movement of the movable transmission component 10 will drive the baffle plate 30 to move along the movable through slot 8. Since the baffle plate 30 is relatively long, it is not easy for the movable through slot 8 to be exposed during the movement, so that the movable through slot 8 is always in a blocked state during the position adjustment of the movable transmission component 10.
[0027] The bottom of the movable shielding component 9 is rotatably connected to a movable transmission component 10. The top end of the movable transmission component 10 passes through the movable shielding component 9 and is fixedly connected to the bottom end of the movable cleaning roller 3. The two ends of the telescopic component 6 are fixedly connected to the opposite ends of the positioning transmission component 7 and the movable transmission component 10, respectively. The movable transmission component 10 includes a first movable bevel gear 26, a second movable bevel gear 27, a movable frame 28, and a fixed connecting rod 29. The first movable bevel gear 26 is rotatably connected to the bottom of the cleaning box 1 at the position corresponding to the movable through slot 8. The top end of the first movable bevel gear 26 passes through the movable through slot 8 and extends into the interior of the cleaning box 1, where it is fixedly connected to the bottom end of the movable cleaning roller 3. The second movable bevel gear 27 meshes with the first movable bevel gear 26 and is fixedly connected to the end face of the adjusting sleeve 20. The movable frame 28 is movably sleeved on the surfaces of the first movable bevel gear 26 and the second movable bevel gear 27. One end of the fixed connecting rod 29 is fixedly connected to the movable frame 28. On the side, the other end of the fixed connecting rod 29 is fixedly connected to the surface of the driving ring 17. During operation, when the adjusting sleeve 20 moves, it will drive the movable frame 28 to move through the second movable bevel gear 27. The movement of the movable frame 28 will synchronously drive the first movable bevel gear 26 and the baffle plate 30 to move. In this way, the movement of the first movable bevel gear 26 will drive the movable cleaning roller 3 to move, thereby adjusting the distance between the positioning cleaning roller 2 and the movable cleaning roller 3, so that it can grind and clean plastic packaging of different specifications. After the distance is adjusted, the telescopic component 6 realizes the transmission function. The rotation of the telescopic component 6 will drive the second movable bevel gear 27 to rotate. The rotation of the second movable bevel gear 27 on the movable frame 28 will drive the first movable bevel gear 26 to rotate. The rotation of the first movable bevel gear 26 will drive the movable cleaning roller 3 at that position to rotate, realizing the purpose of synchronous rotation and cleaning of the positioning cleaning roller 2 and the movable cleaning roller 3. After the distance is adjusted, the telescopic component 6 realizes the efficient transmission effect.
