The driving tube drives the laser engraving head 3 to move and perform engraving under the action of a control terminal;

[0027] The cleaning structure includes a first cleaning plate 8 and a second cleaning plate 17. An auxiliary structure 5 is installed between the first cleaning plate 8 and the second cleaning plate 17. The side wall of the mounting frame 2 is rotatably connected to a reciprocating screw rod 11 and a fixed rod 12, and the reciprocating screw rod 11 and the fixed rod 12 are connected by a belt transmission assembly 16. A transmission structure 4 is installed in the fixed housing 1. The first cleaning plate 8 is fixedly connected to a screw slider 10 that mechanically cooperates with the reciprocating screw rod 11. The first cleaning plate 8 is fixedly connected to a connecting block 18 that is sleeved on the outside of the fixed rod 12. Under the action of the belt transmission assembly 16, the fixed rod 12 rotates with the reciprocating screw rod 11. When the reciprocating screw rod 11 rotates, it drives the screw slider 10 that mechanically cooperates with it to move back and forth, driving the first cleaning plate 8 to move back and forth accordingly;

[0028] The auxiliary structure 5 includes a fixed block 51 fixedly connected to the bottom end of the first cleaning plate 8, a fixed shaft 52 is fixedly connected between the inner walls of the fixed block 51, a fixed sleeve 53 is rotatably sleeved on the fixed shaft 52, a mounting rod 55 is fixedly connected to the fixed sleeve 53, and the mounting rod 55 is fixedly connected to the second cleaning plate 17, a connecting ring 58 is fixedly connected to the side wall of the connecting block 18, a connecting cam 59 is fixedly connected to the side wall of the connecting ring 58, and the connecting cam 59 is slidably sleeved on the outer side of the fixed rod 12, a fixed bracket 56 is fixedly connected to the mounting rod 55, and an extrusion block 57 corresponding to the connecting cam 59 is fixedly connected to the fixed bracket 56, a torsion spring 54 is sleeved on the outer side of the fixed shaft 52, and the two ends of the torsion spring 54 are respectively fixedly connected to the corresponding fixing sleeve 53 and the fixed block 51;

[0029] When the reciprocating screw 11 rotates, it will drive the screw slider 10 that is mechanically matched with it to move back and forth, driving the first cleaning plate 8 to move back and forth. Under the action of the mounting rod 55, the second cleaning plate 17 also moves back and forth. When the first cleaning plate 8 and the second cleaning plate 17 move back and forth, the lens and alloy plate of the laser engraving head 3 are cleaned to facilitate engraving. At the same time, when the fixed rod 12 rotates, the connecting cam 59 that is slidably sleeved on the fixed rod 12 rotates accordingly. When the connecting cam 59 rotates, it squeezes the squeezing block 57, so that the squeezing The pressing block 57 deflects backward, driving the mounting rod 55 to deflect together, causing the fixed sleeve 53 to rotate and the torsion spring 54 to deform. After the connecting cam 59 is separated from the extrusion block 57, the fixed sleeve 53 and the mounting rod 55 return to their original positions under the action of the torsion spring 54, thereby causing the mounting rod 55 to swing back and forth, driving the second cleaning plate 17 to swing back and forth together, thereby improving its cleaning effect on the alloy plate. Finally, the screw slider 10 returns to its initial position, driving the first cleaning plate 8 and the second cleaning plate 17 to return to their initial positions as well, thereby avoiding affecting the engraving.

[0033] An exhaust port is formed on the fixed housing 1, to which a fixed pipe 9 is fixedly connected. The fixed pipe 9 is connected to the processing device. A rotating rod 7 extends into the inner side of the fixed pipe 9, and a fan blade 13 is fixedly connected to the rotating rod 7.

[0037] S1. Input the engraved pattern into the control terminal through the operation panel;

[0038] S2. Place the alloy plate to be engraved on the placement plate, start the motor 6, and the output end of the motor 6 drives the rotating rod 7 to rotate, thereby rotating the fixed worm 14 fixedly sleeved on the rotating rod 7, and rotating the fixed worm wheel 15 meshing with the fixed worm 14, driving the reciprocating screw 11 to rotate together. Under the action of the belt transmission assembly 16, the fixed rod 12 rotates together with the reciprocating screw 11. When the reciprocating screw 11 rotates, it drives the screw slider 10 mechanically matched with it to move back and forth, driving the first cleaning plate 8 to move back and forth accordingly. Under the action of the auxiliary structure 5, the second cleaning plate 17 also moves back and forth. When the first cleaning plate 8 and the second cleaning plate 17 move back and forth, they clean the lens and the alloy plate of the laser engraving head 3 to clean the laser engraving head 3. To facilitate the engraving, at the same time, when the fixing rod 12 rotates, the connecting cam 59 slidably sleeved on the fixing rod 12 rotates accordingly, and the connecting cam 59 squeezes the extrusion block 57 when rotating, causing the extrusion block 57 to deflect backward, driving the mounting rod 55 to deflect together, causing the fixing sleeve 53 to rotate, and the torsion spring 54 to deform. After the connecting cam 59 is separated from the extrusion block 57, under the action of the torsion spring 54, the fixing sleeve 53 and the mounting rod 55 will return to their original positions, thereby causing the mounting rod 55 to swing back and forth, driving the second cleaning plate 17 to swing back and forth together, thereby improving its cleaning effect on the alloy plate. Finally, the screw slider 10 returns to its initial position, driving the first cleaning plate 8 and the second cleaning plate 17 to return to their initial positions, thereby avoiding affecting the engraving.

[0039] S3. Start the laser engraving head 3. The laser engraving head 3 engraves the alloy plate under the control of the control terminal. During the engraving process, metal vapor is generated.

The output end of the motor 6 drives the rotating rod 7 to rotate, thereby rotating the fixed worm 14 fixedly sleeved on the rotating rod 7, and rotating the fixed worm wheel 15 meshing with the fixed worm 14, driving the reciprocating screw 11 to rotate together. Under the action of the belt transmission assembly 16, the fixed rod 12 rotates with the reciprocating screw 11. When the reciprocating screw 11 rotates, it drives the screw slider 10 mechanically matched with it to move back and forth, driving the first cleaning plate 8 to move back and forth accordingly. Under the action of the mounting rod 55, the second cleaning plate 17 also moves back and forth. When the first cleaning plate 8 and the second cleaning plate 17 move back and forth, the lens of the laser engraving head 3 and the alloy plate are cleaned to facilitate engraving. At the same time, when the fixed rod 12 rotates, the sliding sleeve is engaged. When the screw rod 10 is in the working state, the first cleaning plate 8 and the second cleaning plate 17 are moved back to the working state, thereby improving the cleaning effect of the alloy plate. Finally, the screw slider 10 returns to the initial position, driving the first cleaning plate 8 and the second cleaning plate 17 to return to the initial position to avoid affecting the engraving. The laser engraving head 3 is started and the laser engraving head 3 engraves the alloy plate under the control of the control terminal. At the same time, metal vapor is generated during the engraving process. The rotation of the rotating rod 7 drives the fan blades 13 to rotate, and the air and metal vapor are discharged from the fixed pipe 9.
