[0025] The two support plates 11 arranged on the U-shaped plate 7 are used to support the brush roller 12, so that the brush roller 12 can be adjusted synchronously with the U-shaped plate 7, so that the brush roller 12 can be suitable for cleaning bamboo and wood boards of different thicknesses. The first motor 15 can synchronously drive the sanding belt 9 and the brush roller 12 to operate with the help of the belt 17, making the operation of the two more energy-saving and efficient.

[0026] The debris collection assembly includes a collection box 21, which is mounted on a fixed plate 3. A plurality of chip feed tubes 22 are fixedly connected to the bottom of the collection box 21. The bottom ends of the chip feed tubes 22 pass through the fixed plate 3 and are fixedly connected to a bellows 23. The bottom ends of the bellows 23 are fixedly connected to a chip guide tube 24. A connecting plate 25 is fixedly sleeved on the outside of the plurality of chip guide tubes 24. Two second springs 26 are fixed on the upper surface of the connecting plate 25. Two slide bars 27 are slidably inserted on the connecting plate 25. The second springs 26 are sleeved on the outside of the slide bars 27.

[0027] The air inside the collection box 21 is extracted by the blower 32, so that the inside of the collection box 21 is in a negative pressure state, and the outside air needs to be introduced along the air inlet bin 28. In the process of introducing air, the airflow will suck the debris peeled off by the brush roller 12 into the interior of the collection box 21 for temporary storage, so that the conveyor belt 5 and the sanded bamboo and wood boards can be effectively cleaned. The air inlet bin 28 can be squeezed by the bamboo and wood boards to compress the second spring 26 and move upward, so that the air inlet bin 28 is suitable for cleaning debris on bamboo and wood boards of different thicknesses, thereby better meeting the sanding processing requirements of bamboo and wood boards.

[0028] How this utility works:

[0029] The second motor is started to run, so that the second motor drives the conveyor belt 5 to transmit, and the first motor 15 is started to run, so that the first motor 15 drives the belt 17 to transmit, thereby driving the sanding belt 9 to transmit, and driving the brush roller 12 to rotate, the bamboo and wood board is placed on the conveyor belt 5, and the conveyor belt 5 drives the bamboo and wood board to move toward the sanding belt 9, and the bamboo and wood board is sanded by the sanding belt 9. The position of the sanding belt 9 can be determined according to the actual thickness of the bamboo and wood board to squeeze the U-shaped plate 7 to push the limit plate 20 to move upward, so that the sanding belt 9 can be suitable for sanding processing of bamboo and wood boards with different thicknesses, and the rotating brush roller 12 can move synchronously with the U-shaped plate 7, so that the brush roller 12 can peel off the debris attached to the surface of the bamboo and wood board;

[0030] After being processed by the brush roller 12, the bamboo and wood board will squeeze the two rollers 29, so that the two rollers 29 push the air inlet bin 28 to move upward. During this process, the second spring 26 is compressed and the bellows 23 is also in a contracted state. The blower 32 is started to extract the air inside the collection box 21, so that the inside of the collection box 21 is in a negative pressure state. The collection box 21 introduces external air along the air inlet bin 28, so that the airflow inhaled by the air inlet bin 28 drives the debris into the collection box 21 for temporary storage, thereby ensuring that the debris after sanding of the bamboo and wood board can be processed in time. At regular intervals, the two locks 31 are opened and the box door 30 is rotated to export and clean the debris collected in the collection box 21.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
