[0037] The cleaning mechanism includes a motor B10 connected to one side of the collection frame 3. The motor B10 is bolted to one side of the collection frame 3. A threaded rod 31 is connected inside the collection frame 3, and one end of the threaded rod 31 is connected to the output end of the motor B10. A moving plate 12 is screwed onto the surface of the threaded rod 31. An inclined scraper 13 is connected to one side of the moving plate 12.

A collection box 2 is connected to one side of the support base 4 at the bottom of the discharge port 24.

[0038] The inside of the collection frame 3 is connected to the top of the threaded rod 31 with a protective plate 11. The protective plate 11 can prevent sewage and iron filings from splashing onto the threaded rod 31, avoid corrosion of the threaded rod 31 or affect its normal rotation, extend the service life of the threaded rod 31, and ensure the stable operation of the cleaning mechanism.

[0039] The surfaces of the transmission wheel 8, the adjusting wheel 7, and the positioning wheel 6 are fitted with annular sand belts 5.

[0040] The surface of the upright plate 1 is provided with a sliding groove 9 for sliding the fixed rod 25, and the sliding groove 9 and the upright plate 1 are integrally formed.

[0041] A cylinder 20 is connected to the back of the upright plate 1. The cylinder 20 is bolted to the back of the upright plate 1. A fixed frame 21 is connected to the output end of the cylinder 20. A bearing is provided inside the fixed frame 21. The bearing is sleeved on the surface of the fixed rod 25, and the fixed frame 21 is connected to the surface of the fixed rod 25.

[0042] The positioning disk 22 is internally connected to a screw 27. One end of the screw 27 is connected to a rotating disk 26, and the rotating disk 26 and the screw 27 are fixedly connected. The other end of the screw 27 is connected to a plug block 30, and the plug block 30 and the screw 27 are fixedly connected. Both ends of the screw 27 pass through the positioning disk 22.

[0043] The surface of the upright plate 1 is provided with equally spaced insertion slots 23 for inserting the insertion block 30. The insertion slots 23 and the upright plate 1 are integrally formed.

[0044] A water tank 19 is connected to the back of the upright plate 1. The water tank 19 is connected to the inside of the upright plate 1 by screws. A pipe 14 is connected to one side of the water tank 19 after passing through the upright plate 1. A side plate 15 is connected to the surface of the upright plate 1. A hose 16 is connected to the pipe 14 after passing through the side plate 15. A nozzle 17 is connected to the bottom of the hose 16. The hose 16 can move the nozzle 17 to different positions.

[0045] The screw 27 has an external thread 29 connected to its surface. The external thread 29 and the screw 27 are integrally formed. The positioning disk 22 has an internal thread 28 connected to its interior. The internal thread 28 and the positioning disk 22 are integrally formed. The external thread 29 and the internal thread 28 are matched and screwed together.

[0046] Specifically, during use, after the motor A18 is started, the transmission wheel 8 at its output end rotates accordingly. Since the surface of the transmission wheel 8, the adjusting wheel 7 and the positioning wheel 6 is fitted with an annular sanding belt 5, the annular sanding belt 5 starts to run under the drive of the transmission wheel 8, and then performs sanding back operation on the scissors placed near the sanding belt. The tension of the annular sanding belt 5 can be adjusted by the adjusting wheel 7 to ensure the stability of the sanding belt during operation and to ensure the quality of the sanding back operation.

[0047] When the position of the adjusting wheel 7 needs to be adjusted, the cylinder 20 on the back of the upright plate 1 is activated. The output end of the cylinder 20 pushes the fixed frame 21. The fixed frame 21 is connected to the fixed rod 25. The fixed rod 25 slides in the groove 9 opened on the surface of the upright plate 1, thereby driving the adjusting wheel 7 to move and achieve precise adjustment of the tension and position of the annular sanding belt 5.

[0048] After the adjusting wheel 7 is adjusted to the appropriate position, the rotating disk 26 on one side of the positioning disk 22 is rotated. The rotating disk 26 drives the screw 27 to rotate. The external thread 29 on the surface of the screw 27 matches and engages with the internal thread 28 inside the positioning disk 22. The plug block 30 at the other end of the screw 27 moves accordingly and is inserted into the plug slots 23 that are equally spaced on the surface of the vertical plate 1 to fix the position of the adjusting wheel 7 and ensure that the sanding belt maintains a stable operating state during the operation.

[0049] Water is stored in a water tank 19 on the back of the upright plate 1. A pipe 14 connected to the upright plate 1 runs through one side of the water tank 19 to lead out the water. The pipe 14 runs through the side plate 15 and is connected to a flexible hose 16, which can be flexibly adjusted in position. A nozzle 17 connected to the bottom of the hose 16 sprays water out. During sanding operations, water is sprayed onto the scissors and the ring sanding belt 5. Spraying water can reduce the heat generated during sanding operations and prevent the scissors and sanding belt from being damaged due to overheating. On the other hand, it can wash away the debris on the surface of the scissors and the sanding belt, improving the quality and effect of sanding operations.

[0050] During the shearing and sanding process, wastewater and iron filings are generated. At this time, the motor B10 is started, and the motor B10 drives the threaded rod 31 inside the collection frame 3 to rotate. The moving plate 12 screwed to the surface of the threaded rod 31 moves in a straight line along the threaded rod 31 under the action of the rotation of the threaded rod 31. The inclined scraper 13 connected to one side of the moving plate 12 moves synchronously with the moving plate 12. The bottom of the inclined scraper 13 is connected to the bottom of the collection frame 3. During the movement, the inclined scraper 13 scrapes the wastewater and iron filings at the bottom of the collection frame 3, causing them to move towards the discharge port 24 opened on one side of the collection frame 3. The wastewater and iron filings fall into the collection box 2 located at the bottom of the discharge port 24 on one side of the support base 4 through the discharge port 24, realizing the collection and cleaning of the waste generated during the operation and keeping the working environment clean.

[0051] The protective plate 11 located inside the collection frame 3 and connected to the top of the threaded rod 31 can prevent sewage and iron filings from splashing onto the threaded rod 31, avoid corrosion of the threaded rod 31 or affecting its normal rotation, extend the service life of the threaded rod 31, and ensure the stable operation of the cleaning mechanism.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
