[0018] The present invention adopts the above technical solution to bring the following beneficial effects:

[0019] 1. The invention provides a cleaning mechanism, and through the cooperation of a transmission shaft, a first arc plate, a second arc plate, a dust-free cloth and bristles, the carbonized layer produced by laser engraving can be scraped off and erased while the laser engraving machine is engraving an advertising sign made of plastic. The dust-free cloth and the bristles are driven to rotate in opposite directions during the movement by the provision of gears and racks, and the carbonized layer is peeled off from the surface of the plastic advertising sign and the engraved grooves by the scraping of the bristles. During the wiping process, the dust-free cloth can better absorb and remove the fine carbonized particles and stains such as solvents remaining after being scraped by the bristles, so that the plastic surface reaches a cleaner state. By providing a curved plate and a ball bearing, the dust-free cloth and the bristles are repeatedly moved back and forth during the rotation cleaning process, so that a continuous and uniform friction force is generated between the dust-free cloth, the bristles and the carbonized layer. This repeated scraping action can more effectively peel off the carbonized layer from the plastic surface, thereby solving the problem that the carbonized layer will affect the clarity of the text on the advertising sign proposed in the background technology.

[0020] 2. The invention provides a scraping mechanism and fixed comb teeth to scrape off the carbides stuck between the bristles, thereby continuously keeping the bristles clean. The clean bristles can maintain good elasticity, better adapt to the uneven parts of the surface of the plastic advertising sign, provide more uniform cleaning power, and avoid secondary pollution. By providing the mutual cooperation of the movable comb teeth and the fixed comb teeth, the carbides adhered to the surface of the dust-free cloth can be cleaned. The clean dust-free cloth can better fit the plastic surface and penetrate into the gaps of the carbonized layer, thereby more effectively removing the carbides, thereby improving the cleaning effect of the bristles and the dust-free cloth on the carbonized layer.

[0021] 3. The invention sets a spraying mechanism, and sets a spray airbag and a nozzle so that the dissolved solvent can be sprayed onto the carbonized layer that needs to be cleaned during movement. The dissolved solvent can soften the carbonized layer, making it easier to be removed by the bristles and the dust-free cloth. By setting a push rod to press the horizontal plate and the movable plate, the spray airbag can achieve continuous spraying, so that the dissolved solvent is sprayed more evenly. By setting a plug, a sliding rod, a first triangular top block, a second triangular top block and a cable, no matter which direction the laser engraving machine moves to the left or right, only the spray airbag between the laser engraving machine and the brush can spray the dissolved solvent, thereby avoiding waste of the dissolved solvent.

The second arc plate 405 is fixedly connected to the left side of the transmission shaft 403 through a connecting rod. The right side of the second arc plate 405 is provided with a dust-free cloth. The dust-free cloth is driven to rotate by the second arc plate 405 to wipe off the carbonized layer scraped off by the bristles. During the wiping process, the fine carbonized particles and stains such as solvents remaining after being scraped by the bristles can be better adsorbed and removed, so that the surface of the plastic advertising sign can reach a cleaner state.

[0036] A second slide groove 4015 is provided on the top of the two first sliders 402, and a second slider is slidably connected inside the second slide groove 4015. A bracket 406 is fixedly connected to the top of the second slider, and a top plate 407 is fixedly connected to the top of the two brackets 406. A third slide groove 408 is provided on the top of the top plate 407. The third slide groove 408 is arranged in an "I" shape and includes two X grooves and a Z groove. When the laser engraving machine 3 moves forward and backward along the X axis and performs engraving, it moves forward and backward along the X axis with the third slider 409 without restriction. When the laser engraving machine 3 moves left and right along the Y axis and performs engraving, the top plate 407 is dragged to the left or right by the third slider 409. The third slider 409 is slidably connected inside the third slide groove 408. The laser engraving machine 3 is fixedly connected to the bottom end of the third slider 409. The third slider 409 is arranged at the bottom of the second linear motor 206. The third slider 409 and the laser engraving machine 3 are driven by the first linear motor 204 and the second linear motor 206 to move above the processing groove 201, and the advertising sign fixed by the electric suction cup 202 is laser engraved.

[0037] The front end of the transmission shaft 403 is fixedly connected with a gear 4010, and the top of the desktop 1 is fixedly connected with a rack 4011 through a fixing rod. The gear 4010 meshes with the rack 4011. When the transmission shaft 403 moves left and right, the gear 4010 and the rack 4011 drive the transmission shaft 403 to rotate. The top of the desktop 1 is fixedly connected with a curved plate 4012, and the rear end of the transmission shaft 403 is fixedly connected with a ball 4013. By setting the curved plate 4012 and the ball 4013, moves back and forth during the process of the transmission shaft 403 moving left and right, and improves the cleaning effect of the brush and the dust-free cloth. The ball 4013 is slidably connected to the front side of the curved plate 4012. A first spring 4014 is sleeved on the transmission shaft 403. The rear end of the first spring 4014 is fixedly connected to the ball 4013, and the front end of the first spring 4014 is fixedly connected to the first slider 402 on the back. The first spring 4014 is set to drive the ball 4013 to rebound backward.

[0038] Working principle: first, the advertising sign is fixed to the processing groove 201 by setting the electric suction cup 202, and then the first linear motor 204 and the second linear motor 206 are operated to drive the third slider 409 and the laser engraving machine 3 to move above the processing groove 201, and the laser engraving machine 3 generates a laser to engrave the advertising sign fixed by the electric suction cup 202. When the laser engraving machine 3 moves to the right along the Y-axis, it will drag the top plate 407 to the right through the third slider 409, and the top plate 407 moves to the right and drives the third slider 409 to move to the right through the bracket 406. The third slider 409 moves to the right and drives the transmission shaft 403 to move to the right, and rotates counterclockwise under the action of the gear 4010 and the rack 4011. In the process of the transmission shaft 403 moving to the right, the ball 4013 and the curved plate 4012 drive the transmission shaft 403 to move back and forth, thereby the transmission shaft 403 rotates counterclockwise. The first arc plate 404, the second arc plate 405, the brush and the dust-free cloth are driven by the connecting rod to rotate counterclockwise while moving back and forth. During the movement of the brush, the carbonized layer is peeled off from the surface of the plastic advertising sign and the engraved grooves by scraping. During the movement of the dust-free cloth, the carbonized layer scraped off by the brush is erased, thereby completing the cleaning of the carbonized layer while laser engraving. After the laser engraving machine 3 moves to the rightmost end of the desktop 1 and completes the engraving of the advertising sign, the engraved advertising sign is removed, and then the next advertising sign to be processed can be fixed to the processing groove 201 through the electric suction cup 202, and then the above operation is repeated in reverse, the third slider 409 and the laser engraving machine 3 are moved along the Z groove to the left X groove, and the advertising sign is engraved from right to left, and the top plate 407, the brush and the dust-free cloth are dragged to move to the left.

[0039] See also Figure 1-9On the basis of the above embodiment, in another embodiment of the present invention, a scraping mechanism 5 is arranged above the transmission shaft 403, and the scraping mechanism 5 includes a box body 501, and the box body 501 is fixedly connected between the two brackets 406. Two garbage chambers 502 are arranged inside the box body 501. An arc groove 503 is opened at the bottom of the box body 501. The first arc plate 404 and the second arc plate 405 are arranged in the arc groove 503. A plurality of fixed comb teeth 504 are fixedly connected to the upper part of the arc groove 503, and are divided into two groups of arrays. The two groups of fixed comb teeth 504 are respectively arranged above the two garbage chambers 502. The fixed comb teeth 504 are in contact with the bristles. When the bristles rotate counterclockwise, they will be stuck between the plurality of fixed comb teeth 504, and the carbides stuck between the bristles will be scraped off by the fixed comb teeth 504, and the scraped carbides will roll into the garbage chamber 502.

[0040] The inner wall of the box body 501 is fixedly connected with telescopic rods 505 on both sides, and the other end of the telescopic rod 505 away from the inner wall of the box body 501 is fixedly connected with a movable rod 507, and a plurality of movable comb teeth 508 are fixedly connected to the movable rod 507, and the movable comb teeth 508 are staggered with the fixed comb teeth 504. The outer sleeve of the telescopic rod 505 is provided with a second spring 506, and one end of the second spring 506 is fixedly connected to the inner wall of the box body 501, and the other end of the second spring 506 away from the inner wall of the box body 501 is fixedly connected to the movable rod 5 07 fixed connection, a semi-dome block 509 is fixedly connected to the middle part of the transmission shaft 403 and is arranged on one side of the bristles. The rotation of the transmission shaft 403 drives the semi-dome block 509, the bristles and the dust-free cloth to rotate at the same time. The semi-dome block 509 and the bristles are always on the same side. The semi-dome block 509 is in contact with the movable comb teeth 508. The telescopic rod 505 is driven to rebound by setting a second spring 506. When the movable comb teeth 508 and the fixed comb teeth 504 are intertwined, a scraper is formed to scrape off the carbide adhered to the surface of the dust-free cloth.

[0041] The laser engraving machine 3 includes a focusing lens, which is arranged at the bottom end of the laser engraving machine 3. A lens paper 5010 is arranged on the top of the box body 501. The lens paper 5010 is slidably connected to the bottom of the focusing lens. When the laser engraving machine 3 moves in the Z groove, the focusing lens will rub against the lens paper 5010 and wipe off the dust and stains on its surface through the lens paper 5010.

[0042] Working principle: The rotation of the transmission shaft 403 will drive the bristles to rotate together with the semi-dome block 509, and push the movable comb teeth 508 and the movable rod 507 into the interior of the box body 501 through the semi-dome block 509, and compress the telescopic rod 505. At this time, the bristles only contact with the fixed comb teeth 504 and are stuck between several fixed comb teeth 504. The fixed comb teeth 504 are used to scrape off the carbide stuck between the bristles, and the scraped carbide will roll into the garbage cavity 502. When the dust-free cloth contacts the fixed comb teeth 504, the semi-dome block 509 has been out of contact with the movable comb teeth 508. At this time, under the rebound action of the second spring 506, the movable rod 507 and the movable comb teeth 508 rebound, and the movable comb teeth 508 and the fixed comb teeth 504 are intertwined to form a scraper, and the carbide adhered to the surface of the dust-free cloth is scraped off.
