A first guide groove 820c is provided on the front side wall of the slider 820. A first one-way rack 820c-1 is installed at the bottom of the first guide groove 820c. The first one-way rack 820c-1 meshes with the first one-way gear 710b-1. A slidable connection 750 is provided on the side wall of the housing 710. A 750a and a 750b-1 are provided on the side wall of the 750. A 750a-1 is installed at the bottom of 0a. The second one-way gear 740a is located inside 750a and meshes with 750a-1. A 750b is installed at the bottom of 750, and 750b meshes with the first gear 710b-3. Not shown in the figure, the electrostatic adsorption plate 740 integrates an electrostatic generator. It uses static electricity to adsorb the dust scattered by the cleaning brush 730a-1 onto the surface of the electrostatic adsorption plate 740. When the rubber-coated transmission wheel 720a rotates, it drives the third helical gear 720c to rotate. The third helical gear 720c drives the fourth helical gear 720d-2 and the fifth pulley 720d-3 to rotate. The fifth pulley 720d-3 drives the sixth pulley 810a-1 and the reciprocating threaded rod 810a to rotate via a belt.A lead screw mechanism drives slider 820 to move back and forth in a reciprocating motion. As slider 820 moves, it drives scraper 820a to clean the surface below electrostatic adsorption plate 740, removing dust. Each time slider 820 moves backward until the first one-way rack 820c-1 meshes with the first one-way gear 710b-1, the rack 820c-1 drives the first one-way gears 710b-1 and 710b-3 to rotate. The first gear 710b-3 then pushes 750b and 750 to the right. Not shown in the figure, a spring is installed between the sidewall of 750 and the sidewall of the housing 710. When 750 moves to the right, a spring presses down... When the spring 750 moves to the right, 750a-1 drives the second one-way gear 740a to rotate, which in turn drives the electrostatic adsorption plate 740 to rotate 180°, completing the flipping of the electrostatic adsorption plate 740 inside the second slot 710a-4. When the slider 820 moves to the point where the first one-way rack 820c-1 separates from the first one-way gear 710b-1, the spring rebounds and pushes 750 back to its original position. This prevents dust from accumulating on the surface of the electrostatic adsorption plate 740 and affecting the adsorption effect. At the same time, the scraper 820a cleans the surface below the flipped electrostatic adsorption plate 740 each time it moves, preventing dust generated during cleaning of the electrostatic adsorption plate 740 from being adsorbed again onto the sleeve surface.

A threaded rod 910a is rotatably connected to the right side wall of the fifth fixing plate 910, and a fifth helical gear 910b is rotatably connected to the left side wall of the fifth fixing plate 910. The threaded rod 910a and the fifth helical gear 910b are coaxially fixedly connected. A sixth helical gear 920a is mounted on the side wall of the turntable 920, and the sixth helical gear 920a meshes with the fifth helical gear 910b. A third gear 920b is rotatably connected to the inner wall of the cleaning chamber 710b. The third gear 920b is coaxially and fixedly connected to the sixth helical gear 920a.

There is a first one-way valve 930c-1. An air outlet pipe 930d is installed on the right side wall of the fixed pipe 930a. A second one-way valve 930d-1 is installed on the body of the air outlet pipe 930d. The other end of the air outlet pipe 930d extends into the second accommodating cavity 120. When the slider 820 moves to the right each time, the flat rack 820d-1 drives the third gear 920b and the turntable 920 to rotate. The turntable 920 drives the sixth helical gear 920a to rotate. When the sixth helical gear 920a rotates, it drives the fifth helical gear 910b and the threaded rod 910a to rotate. The threaded rod 910a uses a screw structure to push the piston 930b to move into the fixed pipe 930a. At this time, the first one-way valve 930c-1 closes, and the second one-way valve 930d-1 closes. When the fixed tube 930a is opened, the air inside is compressed through the air outlet 930d and blown towards the laser marking and focusing assembly 600 to dissipate heat. When the slider 820 moves to the left to reset, the flat rack 820d-1 drives the third gear 920b to reverse, which in turn drives the threaded rod 910a to reverse, pushing the piston 930b to move out of the fixed tube 930a. At this time, the second one-way valve 930d-1 is closed and the first one-way valve 930c-1 is opened. Air enters the fixed tube 930a through the first one-way valve 930c-1, which can provide air cooling for the laser marking and focusing assembly 600 during the advance of the sleeve, preventing the laser marking and focusing assembly 600 from overheating due to continuous operation.
