Two groups of fixing blocks 17 are threadedly connected to the surface of the second forward and reverse lead screw 16. The dust suction port 7 and the conveying plate 3 are arranged in parallel. The dust suction port 7 arranged in parallel with the conveying plate 3 can better adsorb the dust on the top of the conveying plate 3. The two groups of sliders 11 form a reverse sliding structure through the first forward and reverse lead screw 10. The two groups of rotating plates 12 are in an inverted "V" shape structure. Turn on the servo motor 9 to control the rotation of the first forward and reverse lead screw 10. At this time, the two groups of sliders 11 will approach each other along the installation frame 4, applying power to the movement of the rotating plate 12. The contact point between the rotating plate 12 and the dust suction port 7 is located at the tail of the rotating plate 12, and the rotating plate 12 is controlled to rotate around the dust suction port 7. When the two groups of sliders 11 move, they will drive the rotating plate 12 to rotate. When the rotating plate 12 rotates, a downward thrust will be applied to the dust suction port 7.

The two groups of fixing blocks 17 will gradually disengage from the bottom of the baffle 15 through sliding. At this time, the baffle 15 can be pulled out from the inside of the card slot 14 to achieve the purpose of quickly disassembling the baffle 15. The bottom of the baffle 15 is closely attached to the fixing block 17. The baffle 15 forms a fixed structure inside the card slot 14 through the fixing block 17. By setting the baffle 15, the baffle 15 covers the sides of the processing table 2, effectively avoiding, when processing materials,The problem of chip splashing.,

When it is transported to the processing equipment body 13, the processing equipment body 13 processes it. When the material is being conveyed, the dust suction port 7 is located at the uppermost position and will not affect the movement of the material. When it is necessary to clean the dust on the surface of the conveying plate 3, the servo motor 9 can be turned on to control the rotation of the first positive and negative lead screw 10. At this time, the two groups of sliders 11 will approach each other along the installation frame 4, and the movable plate 12 will be controlled to rotate around the dust suction port 7. When the movable plate 12 rotates, a downward thrust will be applied to the dust suction port 7, causing it to drive the sliding plate 8 to slide downward and move to the position in contact with the conveying plate 3, and start to adsorb the dust on the surface of the conveying plate 3. At this time, the suction pipe 6 is in a vertical state, which can avoid the dust not passing through the inside of the suction pipe 6 normally due to the bending of the suction pipe 6. After the adsorption is completed, the dust suction port 7 is controlled to move to the initial position without affecting the normal transportation of the material.

[0029] By setting the baffle 15, the baffle 15 blocks the side of the processing table 2, effectively avoiding the problem of chip splashing during material processing. When it is necessary to disassemble the baffle 15, turn the second positive and negative lead screw 16 to control the two groups of fixing blocks 17 to slide and approach each other at the bottom of the installation frame 4. The two groups of fixing blocks 17 will gradually disengage from the bottom of the baffle 15 through sliding. At this time, the baffle 15 can be pulled out from the inside of the card slot 14 to achieve the purpose of quickly disassembling the baffle 15.
