It is mainly used for sanding and polishing the surface of materials such as metal and wood. It uses synthetic resin as an adhesive and is suitable for dry sanding. It is often used for sanding wood, metal and putty layers. It has anti-static and anti-clogging properties.

[0003] As disclosed in Chinese Patent No. CN220844659U, a sandpaper cutting mechanism relates to the field of cutting mechanism technology. It includes a fixed plate and a conveying device body, and a tensioning assembly. The tensioning assembly includes two fixed blocks, each with a positioning wheel fixed near its sides. In this invention, when sandpaper needs to be cut, the sandpaper is first placed on the outer surface of the winding roller, the drive motor is started to rotate the paper roll, and then one end of the sandpaper passes over the top of the nearest positioning wheel. The tensioning assembly ensures uniform tension on the sandpaper surface, and the sandpaper is then conveyed to the conveying device body for cutting by a cutting blade. The tensioning assembly ensures uniform quality among the multiple pieces of sandpaper cut by the cutting blade.

[0004] Existing sandpaper cutting machines have limitations. Due to the varying specifications of the sandpaper being produced, the thickness of the sandpaper during cutting also varies. However, the common conveyor structure of these machines cannot easily change the spacing of the conveyor. Therefore, this paper proposes a new sandpaper cutting machine to address these issues.

[0023] 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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a cutting machine for sandpaper cutting. (Refer to...) Figure 3 and Figure 5 The system includes a cutting machine body 1, a conveyor frame 10 fixedly connected to the top of the cutting machine body 1, a limit rod 14 fixedly connected to the inner wall of the conveyor frame 10, a servo motor 12 mounted on the top of the conveyor frame 10, a single-threaded screw 13 fixedly connected to the output end of the servo motor 12, the single-threaded screw 13 rotatably connected to the inner wall of the conveyor frame 10, a conveyor body 16 threadedly connected to the outer wall of the single-threaded screw 13, an adjusting slider 15 fixedly connected to the outer wall of the conveyor body 16, the adjusting slider 15 slidably connected to the outer wall of the limit rod 14, a conveyor motor 25 mounted on one side of the conveyor body 16, a conveyor roller 26 fixedly connected to the output end of the conveyor motor 25, and the conveyor roller 26 rotatably connected to... On the inner wall of the conveying body 16, one end of the conveying roller 26 is fixedly connected to a pulley 17 through the conveying body 16. The outer wall of the pulley 17 is connected to a belt 18. Through the servo motor 12, the servo motor 12 can drive the single-threaded screw 13 to rotate, thereby causing the conveying body 16 and the adjusting slider 15 to slide at the upper limit on the outer wall of the limit rod 14. This achieves the function of controlling the overall rise or fall of the conveying roller 26. After the conveying motor 25 is started, the conveying roller 26 can be made to rotate, thereby playing an auxiliary feeding role. At the same time, the pulley 17, in conjunction with the belt 18, can achieve the function of controlling the synchronous transmission and feeding of the conveying roller 26.

[0026] Reference Figure 2 and Figure 4 A pressing frame 8 is fixedly connected to the top of the cutting machine body 1. A second electric push rod 9 is installed on the inner wall of the pressing frame 8. A pressing block 19 is fixedly connected to the output end of the second electric push rod 9. A pressing auxiliary block 23 is slidably connected to the inner wall of the pressing block 19. A pressing roller 24 is rotatably connected to the inner wall of the pressing auxiliary block 23. By setting the pressing frame 8, the second electric push rod 9 installed on the pressing frame 8 can push the pressing block 19 down as a whole. And because the pressing auxiliary block 23 can slide in a limited position on the inner wall of the pressing block 19, the pressing roller 24 can move the pressing auxiliary block 23 on the inner wall of the pressing block 19 after contacting the sandpaper.

[0027] Reference Figure 2 and Figure 4 A pressure switch 11 is installed on the top of the pressing auxiliary block 23. The pressure switch 11 is electrically connected to the second electric push rod 9. A damping rod 20 is fixedly connected to the top of the pressing auxiliary block 23. The pressure switch 11 is set so that when the pressing auxiliary block 23 rises, the pressure switch 11 will abut against the pressing block 19, thereby allowing the pressure switch 11 to close the second electric push rod 9 after startup.

[0028] Reference Figure 2 and Figure 4 The top of the damping rod 20 is fixedly connected to a top block 21. The top block 21 is fixedly connected to a spring 22 via a pressing block 19. The spring 22 is configured such that when the pressing auxiliary block 23 rises, the damping rod 20 and the top block 21 rise together, thereby causing the spring 22 to be in a stretched state. This allows the second electric push rod 9 to lower the pressing roller 24 to abut against the sandpaper by using the spring 22 when the pressing block 19 stops falling, thus providing appropriate force to press the sandpaper.

[0029] Reference Figure 1 and Figure 2 A cutting frame 4 is fixedly connected to the top of the cutting machine body 1. A first electric push rod 5 is installed on the inner wall of the cutting frame 4. The cutting frame 4 is configured so that the first electric push rod 5 can be installed on the inner wall of the cutting frame 4.

[0030] Reference Figure 1 and Figure 2 The output end of the first electric push rod 5 is fixedly connected to a cutting slider 6, and the bottom of the cutting slider 6 is fixedly connected to a cutting blade 7. The first electric push rod 5 is configured to lower the cutting slider 6 and the cutting blade 7 for cutting.

[0031] Reference Figure 1 and Figure 2 A metal plate 2 is fixedly connected to the top of the cutting machine body 1. A cutting groove 3 is provided on the top of the metal plate 2. The metal plate 2 and the cutting groove 3 are set so that the metal plate 2 and the cutting groove 3 can play an auxiliary cutting role.

[0032] Working principle: The servo motor 12 drives the single-threaded screw 13 to rotate, which in turn causes the conveyor body 16 and the adjusting slider 15 to slide at the upper limit on the outer wall of the limiting rod 14. This controls the overall raising or lowering of the conveyor roller 26. After starting the conveyor motor 25, the conveyor roller 26 rotates, assisting in feeding. The pulley 17, in conjunction with the belt 18, enables synchronous transmission and feeding of the conveyor roller 26. The pressing frame 8 allows the second electric push rod 9 mounted on it to push the pressing block 19 downwards. Because the pressing auxiliary block 23 can slide at the inner wall of the pressing block 19, the pressing roller 24 contacts the sandpaper, causing the pressing auxiliary block 23 to move along the inner wall of the pressing block 19, thus applying pressure. The switch 11 is configured such that when the auxiliary pressing block 23 rises, the pressure switch 11 will abut against the pressing block 19, thereby allowing the pressure switch 11 to close the second electric push rod 9 after activation. The spring 22 is configured such that when the auxiliary pressing block 23 rises, the damping rod 20 and the top block 21 rise together, causing the spring 22 to be in a stretched state. This allows the second electric push rod 9 to descend and press the pressing roller 24 against the sandpaper when the pressing block 19 stops falling, thus providing appropriate pressure on the sandpaper. The cutting frame 4 is configured such that the first electric push rod 5 can be installed on the inner wall of the cutting frame 4. The first electric push rod 5 allows the cutting slider 6 and cutting blade 7 to descend for cutting. The metal plate 2 and cutting groove 3 are configured such that they can assist in cutting.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
