[0032] Please refer again Figure 2 A rotating groove 350 is provided in the middle of the top of the connecting frame 340, a threaded rod 360 is screwed through the middle of the top of the mounting frame 310 through a thread, a hand wheel 370 is fixedly connected to the top of the threaded rod 360, a clamping plate 380 is fixedly connected to the bottom end of the threaded rod 360, a sanding drum 400 is rotatably connected to the left and right sides of the inner front and rear parts of the connecting frame 340, and a driving motor 410 is fixedly connected to the left and right parts of the front side of the connecting frame 340.

[0033] In summary, by rotating the hand wheel 370, the threaded rod 360 is driven to rotate, and the threaded rod 360 is screwed to the mounting frame 310. When the threaded rod 360 rotates, the threaded rod 360 moves, thereby driving the connecting frame 340 to move, and adjusting the position of the sanding drum 400, so as to facilitate adjustment according to the thickness of the plywood, making the adjustment more convenient and easy to apply to different plate processing, thereby improving the applicability of the device.

[0034] Please refer again Figure 2 The left and right sides of the slider 330 fit with the left and right sides of the slide groove 320, and the slider 330 is T-shaped.

[0035] Please refer again Figure 2 The input end of the driving motor 410 is electrically connected to the output end of the external power supply, and the output shaft end of the driving motor 410 is fixedly connected to the front end of the transmission shaft of the sanding drum 400 .

[0036] Please refer again Figure 3 The clamping plate 380 is rotatably clamped in the interior of the rotating groove 350 .

[0037] Please refer again Figure 4 A cleaning mechanism 500 is fixedly connected to the left and right sides of the top of the conveyor belt 100. The cleaning mechanism 500 includes a fixed frame 510, a mounting groove 520, a rotating shaft 530, a connecting block 540, a cleaning brush 550 and a torsion spring 560. The front and rear parts of the left and right sides of the top of the conveyor belt 100 are fixedly connected to the fixed frame 510. A mounting groove 520 is provided in the middle of the top of the front and rear parts of the inner side of the fixed frame 510. The rotating shaft 530 is rotatably connected to the middle of the opposite sides of the mounting grooves 520 of the front and rear parts. The opposite ends of the rotating shafts 530 of the front and rear parts are fixedly connected to the connecting blocks 540. The bottom of the connecting block 540 is fixedly connected to the cleaning brush 550, and the outer side of the rotating shaft 530 is sleeved with a torsion spring 560.

[0038] Please refer again Figure 4 The torsion spring 560 is located inside the mounting groove 520 , and two ends of the torsion spring 560 are fixedly connected to the mounting groove 520 and the opposite sides of the connecting block 540 , respectively.

[0039] To sum up, when the plywood contacts the cleaning brush 550, the cleaning brush 550 is squeezed, causing the cleaning brush 550 to deflect, driving the connecting block 540 to deflect, thereby deforming the torsion spring 560.

It cleans before sanding to ensure the cleanliness of the plywood and avoid impurities affecting the sanding quality. It cleans after sanding to clean the wood chips on the plywood and avoids subsequent manual cleaning, thereby improving the practicality of the device.

[0040] In specific use, the technical personnel in this field first place the plywood on the conveyor belt 100, at the bottom of the sanding drum 400, turn the hand wheel 370 to drive the threaded rod 360 to rotate, and the threaded rod 360 is screwed to the mounting frame 310. When the threaded rod 360 rotates, the threaded rod 360 moves, thereby driving the connecting frame 340 to move, and adjusting the position of the sanding drum 400 so that the sanding drum 400 fits the top of the plywood. The plywood is taken out and placed on the left side of the conveyor belt 100, and the conveyor belt 100 and the driving motor 410 are started. By starting the conveyor belt 100, the plywood is sanded. When the plywood contacts the cleaning brush 550, the cleaning brush 550 is squeezed to deflect the cleaning brush 550, driving the connecting block 540 to deflect, thereby deforming the torsion spring 560. The deformation of the torsion spring 560 causes the cleaning brush 550 to have a tendency to rotate, thereby making the cleaning brush 550 fit closely to the surface of the plywood for cleaning before sanding. When the plywood moves to the sanding drum 400, the driving motor 410 is started to drive the sanding drum 400 to rotate and sand the plywood. Then the plywood moves to the cleaning mechanism 500 on the right side to clean the debris on the outside of the plywood and complete the sanding.
