Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for sandpaper processing. Background Technology

[0002] Sandpaper is a coated abrasive tool made of flexible materials such as paper or cloth as a base, with abrasive particles such as alumina and silicon carbide evenly coated on it and firmly attached with the help of an adhesive. It is used for grinding, polishing, rust removal and roughness adjustment of material surfaces.

[0003] In the process of processing sandpaper into products that meet the specifications of various sanding scenarios, a cutting device is usually required to precisely cut it into specific shapes and sizes. Sandpaper cutting devices utilize motor drives, cutting tools, and automated control components to achieve efficient and high-precision cutting of sandpaper, meet diverse production needs, and significantly improve sandpaper processing efficiency and product quality.

[0004] However, existing sandpaper cutting devices have the following shortcomings:

[0005] In the existing technology, the cutting device for sandpaper processing usually requires manual pushing of sandpaper into the cutting device to complete the cutting operation. However, this manual feeding method is affected by human factors, resulting in unstable feeding speed and large positional deviation, making it difficult to guarantee the cutting size accuracy, resulting in inconsistent product quality. At the same time, manual operation is inefficient and cannot meet the needs of large-scale, high-efficiency production.

[0006] Therefore, we propose a cutting device for sandpaper processing to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a cutting device for sandpaper processing. By using a motor drive combined with the transmission of a bevel gear set, two conveyor belts can rotate synchronously, thereby driving the sandpaper to be accurately transported to the cutting component for efficient cutting. By rotating the handle and using the threaded transmission mechanism, the distance between the two conveyor belts can be flexibly adjusted to achieve stable clamping of sandpaper of different thicknesses, thus solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a sandpaper cutting device, comprising an operating table, a fixed frame fixedly connected to the outer wall of the operating table, four first sliding grooves opened on the inner wall of the fixed frame, sliders slidably embedded in the inner walls of the four first sliding grooves, a first conveying frame fixedly connected between the outer walls of the four sliders, a threaded groove opened on the top of the fixed frame, an adjusting screw threadedly connected to the inner wall of the threaded groove, a throttle fixedly connected to the top of the adjusting screw, a first bearing fixedly sleeved on the outer wall of the adjusting screw, and the outer wall of the first bearing fixedly inserted inside the first conveying frame, a second conveying frame fixedly connected to the top of the operating table, two sets of second bearings inserted into the inner walls of both the first and second conveying frames, conveying rollers fixedly inserted between the interiors of the four sets of second bearings, a conveyor belt movably sleeved between the outer walls of the two sets of conveying rollers, and a first bevel gear fixedly sleeved on the outer walls of two of the two sets of conveying rollers.

[0009] Preferably, the outer walls of the two first bevel gears are meshed with second bevel gears, a rotating shaft is fixedly inserted into the inner wall of one of the two second bevel gears, a drive motor is fixedly connected to the bottom of the rotating shaft, two locking blocks are fixedly connected to the outer wall of the rotating shaft, two locking slots are opened on the top of the other of the two second bevel gears, and the outer walls of the two locking blocks are movably inserted into the two locking slots.

[0010] Preferably, two bearing seats are fixedly sleeved on the outer wall of the rotating shaft, and two sets of fixing plates are fixedly installed on the top of the operating table, with a third bearing fixedly inserted into the inner wall of each of the two sets of fixing plates.

[0011] Preferably, guide rollers are fixedly inserted between the interiors of the two sets of third bearings, and a mounting frame is fixedly connected to the top of the operating table. Two second sliding grooves are formed on the inner surface of the mounting frame.

[0012] Preferably, a slide plate is slidably embedded between the inner walls of the two second slide grooves, and an electric push rod is fixedly connected to the top of the slide plate, with the telescopic end of the electric push rod moving through the interior of the mounting frame.

[0014] Preferably, an unwinding assembly is fixedly installed on the top of the operating table, and a cutting assembly is fixedly installed on the top of the operating table.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, through the interaction of the various components of the device, the two conveyor belts can be driven synchronously by a motor and combined with the transmission of a bevel gear set. This drives the sandpaper to be accurately conveyed to the cutting component for efficient cutting. By rotating the handle and using the threaded transmission mechanism, the distance between the two conveyor belts can be flexibly adjusted to achieve stable clamping of sandpaper of different thicknesses. In this way, the automatic feeding function of sandpaper is realized, effectively avoiding the problems of unstable feeding speed and large position deviation caused by traditional manual feeding. This ensures the cutting size accuracy, improves product quality, reduces manual operation, and solves the problem of low efficiency of manual operation, thereby meeting the needs of large-scale and high-efficiency production. In addition, only one power source is needed to make the two conveyor belts rotate synchronously, which greatly simplifies the transmission structure and reduces equipment costs and energy consumption. By adjusting the position of the two conveyor belts, the conveying requirements of sandpaper of different thicknesses can be adapted, thus broadening the application range of the equipment.

[0017] 2. In this invention, the height of the floating roller can be precisely adjusted by utilizing the interaction of the various components of the device, driven by an electric push rod, and combined with the guiding and displacement functions of the sliding component. This adjustment mechanism allows for flexible changes in the distance between the floating roller and the two guide rollers, thereby effectively controlling the tension during sandpaper transport and ensuring that the tension remains stable within a suitable range, thus guaranteeing that the sandpaper remains stable and flat during transport.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in the attached document Figure 1 -Appendix Figure 4As shown, this utility model provides a technical solution: a cutting device for sandpaper processing, including an operating table 1, a fixed frame 2 fixedly connected to the outer wall of the operating table 1, four first sliding grooves 3 opened on the inner wall of the fixed frame 2, sliders 4 slidably embedded in the inner wall of each of the four first sliding grooves 3, a first conveying frame 5 fixedly connected between the outer walls of the four sliders 4, a threaded groove 6 opened on the top of the fixed frame 2, an adjusting screw 7 threadedly connected to the inner wall of the threaded groove 6, a handle 8 fixedly connected to the top of the adjusting screw 7, a first bearing 9 fixedly sleeved on the outer wall of the adjusting screw 7, and the outer wall of the first bearing 9 fixedly inserted into the inside of the first conveying frame 5, a second conveying frame 10 fixedly connected to the top of the operating table 1, and the first conveying frame 5 and the second conveying frame 10... Two sets of second bearings 11 are inserted into the inner surface of the frame 10. Conveyor rollers 12 are fixedly inserted between the four sets of second bearings 11. Conveyor belts 13 are movably sleeved between the outer surfaces of the two sets of conveyor rollers 12. First bevel gears 14 are fixedly sleeved on the outer surfaces of two of the two sets of conveyor rollers 12. Second bevel gears 15 are meshed with the outer surfaces of the two first bevel gears 14. A rotating shaft 16 is fixedly inserted into the inner surface of one of the two second bevel gears 15. A drive motor 17 is fixedly connected to the bottom of the rotating shaft 16. Two locking blocks 18 are fixedly connected to the outer surface of the rotating shaft 16. Two slots 19 are opened on the top of the other of the two second bevel gears 15, and the outer surfaces of the two locking blocks 18 are movably inserted into the two slots 19.

[0026] The overall effect of Embodiment 1 is that, during use, sandpaper is first clamped between two conveyor belts 13. After starting the drive motor 17, its output end drives the rotating shaft 16 to rotate. Through gear transmission, the two conveyor rollers 12 rotate synchronously, thereby driving the two conveyor belts 13 to move and transport the sandpaper to the cutting assembly 31 for cutting. This conveying method avoids the problems of unstable speed and inaccurate positioning of manual conveying, improves cutting accuracy and efficiency, and simplifies the transmission structure by using only one drive source to drive the two conveyor rollers 12, reducing equipment cost and energy consumption. Adjustment is possible without further information. The distance between the two conveyor belts 13 is adapted to accommodate sandpaper of different thicknesses. Simply turn the handle 8, which drives the adjusting screw 7 to rotate, causing the first conveyor frame 5 to move vertically, changing the height of the top conveyor belt 13, and thus adjusting the distance between the two conveyor belts 13, enhancing the versatility of the device. At the same time, the movement of the first conveyor frame 5 drives the top first bevel gear 14 and second bevel gear 15 to move. With the help of the movable cooperation of the two slots 19 and the two blocks 18, the second bevel gear 15 can move vertically, and the rotation of the shaft 16 does not affect its transmission, ensuring the stability and continuity of the transmission.

[0027] Example 2, as Figure 2-4As shown, two bearing seats 20 are fixedly fitted on the outer wall of the rotating shaft 16. Two sets of fixing plates 21 are fixedly installed on the top of the operating table 1. A third bearing 22 is fixedly inserted into the inner wall of each of the two sets of fixing plates 21. A guide roller 23 is fixedly inserted between the interiors of the two sets of third bearings 22. A mounting frame 24 is fixedly connected to the top of the operating table 1. Two second sliding grooves 25 are opened on the inner wall of the mounting frame 24. A sliding plate 26 is slidably embedded between the inner walls of the two second sliding grooves 25. An electric push rod 27 is fixedly connected to the top of the sliding plate 26. The telescopic end of the electric push rod 27 moves through the interior of the mounting frame 24. Two fourth bearings 28 are fixedly inserted into the inner wall of the sliding plate 26. A floating roller 29 is fixedly inserted between the interiors of the two fourth bearings 28. An unwinding assembly 30 is fixedly installed on the top of the operating table 1. A cutting assembly 31 is fixedly installed on the top of the operating table 1.

[0028] The effect achieved by the entire embodiment 2 is as follows: During use, after the sandpaper is unwound by the unwinding assembly 30, it is conveyed forward along the bottom of the two guide rollers 23 and the top of the floating roller 29. When the sandpaper experiences insufficient or excessive tension during conveying, the electric push rod 27 is activated first. After the electric push rod 27 is activated, it drives the slide plate 26, which in turn moves the floating roller 29 in the vertical direction, thereby changing the distance between the floating roller 29 and the two guide rollers 23. This adjusts the tension of the sandpaper conveying, ensuring that the tension is always maintained within a suitable range, and ensuring that the sandpaper is conveyed stably and flatly.

[0029] The working principle of the entire device is as follows: During use, after the sandpaper is unwound by the unwinding assembly 30, it passes around the bottom of the two guide rollers 23 and the top of the floating roller 29 to complete the guiding and conveying process. Subsequently, the sandpaper is conveyed between the two conveyor belts 13. At this time, the throttle 8 is turned, which drives the adjusting screw 7 to rotate. Since the inner wall of the threaded groove 6 is threadedly connected to the outer wall of the adjusting screw 7, the rotation of the adjusting screw 7 will drive the first conveyor frame 5 to move in the vertical direction, thereby changing the vertical height of the top conveyor belt 13, achieving a stable clamping of sandpaper of different thicknesses. After that, the drive motor 17 is started, and its output end drives the rotating shaft 16 to rotate. The rotating shaft 16 drives the two second bevel gears 15 to rotate. This drives the two first bevel gears 14 to rotate, which in turn drives the two conveyor rollers 12 to rotate, causing the two conveyor belts 13 to operate and transport the sandpaper to the cutting assembly 31 for cutting. At the same time, the vertical movement of the first conveyor frame 5 will drive the top first bevel gear 14 and the second bevel gear 15 to move. Through the movable cooperation of the two slots 19 and the two blocks 18, the second bevel gear 15 can move in the vertical direction, and the rotation of the shaft 16 will not affect the transmission of the second bevel gear 15. This ensures that the transmission system can still work stably and reliably when adjusting the spacing of the conveyor belts 13 to adapt to sandpaper of different thicknesses, ensuring the continuity and stability of the sandpaper transport and cutting process.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
