Utility Model Content
[0005] This invention proposes a high-efficiency cutting device for sandpaper production.
[0006] The technical solution of this utility model is as follows: A high-efficiency sandpaper production cutting device includes a cylindrical rod, one end of which is fixedly connected to a cutting table. A precision cutting component is provided on the top of the cutting table. The precision cutting component includes a slide groove, which is opened on the side of the cutting table. A support frame is slidably connected to the inner wall of the slide groove. A support plate is fixedly connected to the bottom of the support frame. A cutting blade is rotatably connected to the inner wall of the support plate. A motor is provided on the side of the cutting blade. A second motor is fixedly connected to the top of the cutting table. A threaded rod is fixedly connected to the output shaft of the second motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A limit rod is fixedly connected to the top of the second motor. The end of the limit rod away from the second motor passes through the bottom of the threaded sleeve. A fixing rod is fixedly connected to the side of the threaded sleeve.
[0007] Furthermore, the fixing rod is located at the top of the cutting table, and the top of the cutting table is fixedly connected to the outer shell. The second motor, the threaded rod, and the threaded sleeve are located on the inner wall of the outer shell. The design of the outer shell helps to protect the second motor, the threaded rod, and the threaded sleeve, reducing direct exposure to the outside.
[0008] Furthermore, the cutting blade is located at the top of the cutting table, and there are two fixing rods that are symmetrical to each other along the vertical central axis of the cutting table. The side of the cutting table is provided with a slot, which is designed to temporarily lock the position of the support frame.
[0009] Furthermore, a locking rod is rotatably connected to the side of the support frame, and the slot is located on the displacement trajectory of the locking rod. Several slots are provided and arranged in a linear array on the side of the cutting table, which facilitates adjusting the support frame to multiple positions.
[0010] Furthermore, there are two outer shells and several cylindrical rods arranged in pairs, symmetrically arranged along the vertical central axis of the cutting table. The two outer shells facilitate the separate protection of the motor, the threaded rod, and the threaded sleeve.
[0011] Furthermore, a descaling assembly is provided on the top of the cutting table.

[0014] The working principle and beneficial effects of this utility model are as follows: 1. This utility model achieves precise cutting accuracy by coordinating the support frame, fixing rod, and other components within the precision cutting assembly. By adjusting the position of the cutting blade and pressing the sandpaper firmly onto the cutting table via the fixing rod, it prevents the sandpaper from shifting during the cutting process and ensures cutting precision. This is crucial for sandpaper quality control on the production line, reducing waste and improving product consistency.
[0015] 2. This utility model achieves effective removal of impurities and dirt debris from the cutting process through the coordinated operation of components such as the rectangular plate and vibrating rod inside the descaling assembly. This avoids the problem of unclean cutting and reduced precision caused by impurities accumulating on the blade, ensuring that each cutting is more precise and clean.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0021] Example 1 like Figures 1-5As shown, this embodiment proposes a high-efficiency sandpaper production cutting device, including a cylindrical rod 1. One end of the cylindrical rod 1 is fixedly connected to a cutting table 2. A precision cutting component 3 is provided on the top of the cutting table 2. The precision cutting component 3 includes a slide groove 31, which is opened on the side of the cutting table 2. A support frame 32 is slidably connected to the inner wall of the slide groove 31. A support plate 33 is fixedly connected to the bottom of the support frame 32. A cutting blade 34 is rotatably connected to the inner wall of the support plate 33. A motor 35 is provided on the side of the cutting blade 34. A motor 37 is fixedly connected to the top of the cutting table 2. A threaded rod 38 is fixedly connected to the output shaft of the motor 37. A threaded sleeve 39 is threadedly connected to the circumferential surface of the threaded rod 38. A limit rod 310 is fixedly connected to the top of the motor 37. The end of the limit rod 310 away from the motor 37 passes through the bottom of the threaded sleeve 39. A fixing rod 311 is fixedly connected to the side of the threaded sleeve 39.
[0022] The fixing rod 311 is located on the top of the cutting table 2. The top of the cutting table 2 is fixedly connected to the outer shell 36. The motor 37, threaded rod 38, and threaded sleeve 39 are located on the inner wall of the outer shell 36. The design of the outer shell 36 helps to protect the motor 37, threaded rod 38, and threaded sleeve 39 and reduce direct exposure.
[0023] The cutting blade 34 is located on the top of the cutting table 2. There are two fixing rods 311, which are symmetrical about each other along the vertical central axis of the cutting table 2. The side of the cutting table 2 is provided with a slot 312. The design of the slot 312 is conducive to temporarily locking the position of the support frame 32.
[0024] A locking rod 313 is rotatably connected to the side of the support frame 32. The slot 312 is located on the displacement trajectory of the locking rod 313. Several slots 312 are provided and arranged in a linear array on the side of the cutting table 2, which is conducive to adjusting the support frame 32 to multiple positions.
[0025] There are two outer shells 36 and several cylindrical rods 1, arranged in pairs and symmetrical to each other along the vertical central axis of the cutting table 2. The two outer shells 36 are convenient for protecting the motor 37, the threaded rod 38, and the threaded sleeve 39 respectively.
[0026] In this embodiment, the sandpaper to be cut is placed on top of the cutting table 2. Motor 35 is started, driving the cutting blade 34 to rotate. The cutting blade 34 efficiently cuts the sandpaper. The position of the cutting blade 34 can be adjusted. Pulling the support frame 32 along the slide groove 31 moves the support plate 33, the cutting blade 34, and motor 35. After adjusting the position of the cutting blade 34, the locking rod 313 is moved closer to the slot 312, inserting it into the slot 312 to lock the positions of the support frame 32 and the cutting blade 34. To prevent the sandpaper from moving during cutting, after adjusting the positions of the sandpaper and the cutting blade 34, motor 37 is started, and motor 37 rotates forward. The screw rod 38 rotates forward, which in turn moves the threaded sleeve 39 downward. The downward movement of the threaded sleeve 39 in turn moves the fixed rod 311 downward. The cutting table 2 is located on the movement trajectory of the fixed rod 311. When the fixed rod 311 moves downward, it moves onto the cutting table 2. At this time, sandpaper is placed on the cutting table 2. The downward movement of the fixed rod 311 can press the sandpaper down from top to bottom, preventing the sandpaper from moving during cutting and improving the cutting accuracy of the sandpaper. By adjusting the position of the cutting blade 34 and pressing the sandpaper firmly onto the cutting table 2 through the fixed rod 311, displacement of the sandpaper during the cutting process is avoided, ensuring the cutting accuracy. This is crucial for the quality control of sandpaper on the production line, reducing waste and improving product consistency.
[0027] Example 2 like Figures 1-5 As shown, based on the same concept as in Embodiment 1 above, a descaling component 4 is provided on the top of the cutting table 2. The descaling component 4 includes a rectangular plate 41. The bottom of the rectangular plate 41 is fixedly connected to the top of the cutting table 2. A circular plate 42 is rotatably connected to the inner wall of the rectangular plate 41. An extension rod 43 is fixedly connected to the circumferential surface of the circular plate 42. A vibration rod 44 is fixedly connected to the circumferential surface of the circular plate 42. The vibration rod 44 strikes the support frame 32, causing the cutting blade 34 to vibrate and remove the cutting waste remaining on the cutting blade 34.
[0028] The extension rod 43 is located on the displacement trajectory of the fixed rod 311, the support frame 32 is located on the displacement trajectory of the vibrating rod 44, and the rectangular plate 41 is fixedly connected to the side of the square plate 45. This design is beneficial to squeeze the extension rod 43 when the fixed rod 311 moves.
[0029] A spring 46 is fixedly connected to the top of the square plate 45. The end of the spring 46 away from the square plate 45 is fixedly connected to the bottom of the vibrating rod 44. The design of the spring 46 is conducive to the automatic reset of the vibrating rod 44 when it is not driven.
[0030] In this embodiment, as the fixed rod 311 moves downward, the extension rod 43 is positioned on the movement trajectory of the fixed rod 311. When the fixed rod 311 moves downward, it will press against the extension rod 43, forcing the extension rod 43 to move downward. The downward movement of the extension rod 43 will cause the circular plate 42 to rotate upward, making the circular plate 42 rotate clockwise. The clockwise rotation of the circular plate 42 will cause the vibrating rod 44 to move upward. The support frame 32 is positioned on the movement trajectory of the vibrating rod 44. When the vibrating rod 44 moves upward, it will strike the support frame 32. The bottom of the support frame 32... The unit is fixed with a support plate 33, a cutting blade 34, and a motor 35. When the support frame 32 is vibrated, it will drive the cutting blade 34 to vibrate, which will shake off the impurities, dirt and debris left on the cutting blade 34 due to cutting, so as to prevent it from affecting the secondary cutting of sandpaper. Through the linkage of the extension rod 43, the circular plate 42 and the vibrating rod 44, the vibration mechanism can effectively remove impurities, dirt and debris on the cutting blade 34. This avoids the problem of unclean cutting and reduced precision caused by impurities accumulating on the blade, and ensures that each cutting is more accurate and cleaner.
[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
