[0042] like Figure 3 , Figure 6 and Figure 7As shown, the dust collecting section 4 includes a circulating suction cylinder 401 fixedly mounted on the side of the lifting cylinder 103; a suction ring 402 is fixedly mounted on the end of the circulating suction cylinder 401; the suction ring 402 is fixedly sleeved inside the lifting cylinder 103; the suction ring 402 is used to suck the smoke from the laser engraving; a circulating fan 403 is fixedly mounted inside the circulating suction cylinder 401 through a bracket; the circulating fan 403 consists of a motor and an impeller; an inert gas connecting pipe 404 is fixedly mounted on the top of the circulating suction cylinder 401; a valve is provided on the inert gas connecting pipe 404; the inert gas connecting pipe 404 is used to connect an inert gas bottle; the inert gas recycling part 5 includes a filter cover 501 threadedly connected to the circulating suction cylinder 401; a filter element 5011 is provided on the filter cover 501; the filter element 5011 is used to filter the smoke from the laser engraving; a recycling pipe 502 is fixedly mounted on the filter cover 501; the end of the recycling pipe 502 passes through the lifting cylinder 103; the recycling pipe 50 2 ends are used to centrally spray out inert gas. The ring dust suction part 4 can be used to easily recycle the smoke generated by engraving, which can promote environmentally friendly production, reduce the odor of laser engraving, and improve the environmental quality. The inert gas recycling part 5 can fully filter the smoke. At the same time, the inert gas recycling part 5 can be used to easily recycle the inert gas and reduce the gas protection cost. At the same time, the recycling pipe 502 used can directly spray the smoke to the laser focus of the laser engraving machine head body 101, focusing on the inert gas protection of the engraving position, further reducing the yellowing of the engraving. At the same time, the structure circulates smoothly and automatically filters, and the filter cover 501 can be easily removed to clean the filter element 5011; open the valve on the inert gas connecting pipe 404 to introduce part of the inert gas. At this time, as the engraving proceeds, when the leather is punched, the conduction of the inert gas is also realized, and the closed shell 201 is also filled with inert gas, and the sealing performance of the leather is improved by the closed rubber ring 106.

[0043] like Figure 8As shown, the safety protection member 6 includes a closing plate 601 slidably mounted on the lifting cylinder 103; a reset spring piece 602 is fixedly mounted on the closing plate 601; the reset spring piece 602 is fixedly mounted on the outside of the lifting cylinder 103; the reset spring piece 602 is a "V"-shaped structure; a paddle 603 is fixedly mounted on the bottom of the closing plate 601; the paddle 603 is located inside the lifting cylinder 103; a protective pad 604 is fixedly mounted on the top of the closing plate 601; the protective pad 604 is used to protect the bottom end of the laser engraving machine head body 101; the protection control member 7 includes a switch control panel 701 fixedly mounted on the lifting cylinder 103; a switch control column 702 is mounted on the switch control panel 701; the outer side of the top of the switch control column 702 is a slope structure; the outer side of the top of the switch control column 702 squeezes and fits the paddle 603; the switch control column 702 is used to press and fit on the leather surface. This structure adopts the protection control member 7 and can use the leather after installation to control safety The protective piece 6 switch adopts the safety protective piece 6 to improve the protection effect of the laser engraving head body 101, automatically closes and shields the laser engraving head body 101, and has a better dustproof effect. At the same time, it can also prevent the staff from being burned by the laser of the laser engraving head body 101 after the laser engraving is completed, thereby improving the safety of the use of this structure and avoiding safety accidents. If the staff removes the leather, the laser of the laser engraving head body 101 is not turned off in time. At this time, the switch control column 702 loses the limit of the leather. At this time, under the extrusion of the reset spring piece 602, the closing plate 601 moves to the side close to the laser engraving head body 101. At this time, the switch control column 702 loses the limit of the leather and is moved down by the paddle 603. The protective pad 604 can be attached to the bottom of the laser engraving head body 101 for protection. At this time, the ray focus of the laser engraving head body 101 is not at the height of the protective pad 604, and the protective pad 604 will not be damaged.

[0044] like Figure 3 , Fig.10 and Fig.11As shown, the carbonization detection part 8 includes a detection mounting column 801 fixedly mounted on the lifting cylinder 103; a motor connecting seat 802 is rotatably mounted on the detection mounting column 801; a driving motor 803 is fixedly mounted on the motor connecting seat 802; the carbonization detection part 8 also includes a sliding connecting shaft 804 fixedly mounted on the output shaft of the driving motor 803, and the sliding connecting shaft 804 is a hexagonal column structure; a connecting slide 805 is slidably sleeved on the sliding connecting shaft 804; an adapter spring 806 is sleeved inside the connecting slide 805; a wiping brush disc 807 is fixedly mounted on the bottom of the connecting slide 805; one end of the adapter spring 806 is fixedly mounted on the bottom of the sliding connecting shaft 804, and the other end of the adapter spring 806 is fixedly mounted on the top of the wiping brush disc 807; the bristles at the bottom of the wiping brush disc 807 are white cotton soft bristles. The use of the carbonization detection part 8 can facilitate the staff to understand the current laser engraving quality and prevent overheating and other factors from causing laser engraving. Carbonization at the optical engraving position is not discovered, while continuous engraving causes wrinkles on the leather surface due to carbonization and overheating. Especially for laser drilling and engraving work, in order to ensure the actual engraving quality of the leather, the wiping brush plate 807 can be elastically fitted at the engraving position for continuous wiping, which is convenient for the staff to adjust the laser engraving parameters and the staff to observe more intuitively, avoiding the problem that the carbonization is not intuitive enough on the leather surface. At the same time, the heat at the laser engraving position is high and it is not suitable for direct manual contact, wiping and observation. Another function of this structure is that it can facilitate the cleaning of the engraved leather surface, which is more practical. Under the extrusion of the adapter spring 806, the connecting slide 805 will elastically fit on the leather surface, and cooperate with the driving motor 803 to drive the sliding connecting shaft 804 to rotate, so as to control the rotation of the wiping brush plate 807, and use the white cotton soft hair at the bottom to test the engraving position. If carbonization occurs, carbonized black particles will be attached to the white cotton soft hair, and the staff can debug the relevant parameters.

[0045] The working principle provided by the present invention is that firstly, the two sides of the leather clamping platform 301 are installed under the laser engraving machine by bolts, the leather is placed under the two lower pressing plates 303, and the two lower pressing bolts 302 are tightened respectively to squeeze the lower pressing plates 303 to clamp the leather, and the leather is ensured to be flat and tensioned when clamping the leather, the laser engraving head body 101 is installed on the laser engraving machine frame, and the laser engraving machine frame controls the displacement of the laser engraving head body 101 to adjust the laser engraving route. Under the squeezing of the elevation spring 104, the lifting cylinder 103 is attached to the leather surface, and at this time, the electromagnet 105 is controlled to pass the electromagnetic suction set magnetic iron ring 202, so that the magnetic iron ring 202 is attached to the bottom of the leather, and drives the closing shell 201 to follow The laser engraving machine head body 101 moves; the valve on the inert gas connecting pipe 404 is opened to introduce some inert gas. At this time, as the engraving progresses, the inert gas is also conducted when the leather is punched, and the closed shell 201 is also filled with inert gas. The sealing of the leather is improved by the closed rubber ring 106. At this time, the circulating fan 403 is used for suction, and the suction ring 402 inhales the smoke, which is filtered through the filter element 5011 and discharged from the recycling pipe 502 for reuse, and the recycling filtration is carried out. The filter cover 501 is disassembled by rotation to facilitate cleaning of the filter element 5011; after the lower pressure plate 303 clamps the leather, the magnetic iron ring 202 set by the electromagnet 105 is used to magnetically attract the leather to be positioned flat, and the opening is opened. The switch control column 702 will be squeezed upward by the flat leather to squeeze the paddle 603. The paddle 603 is squeezed by the top inclined surface of the switch control column 702 and can move outward. The protective pad 604 no longer blocks the bottom end of the laser engraving head body 101. After welding is completed, if the leather is removed, the laser of the laser engraving head body 101 is not turned off in time. At this time, the switch control column 702 loses the limit of the leather. At this time, under the squeeze of the reset spring piece 602, the closing plate 601 moves to the side close to the laser engraving head body 101. At this time, the switch control column 702 loses the limit of the leather and is moved downward by the paddle 603. The protective pad 604 can fit the bottom end of the laser engraving head body 101 for protection. ; When testing the laser engraving head body 101, discarded scraps can be used. When the laser engraving head body 101 moves for engraving, it drives the carbonization detection part 8 to move together. Under the extrusion of the adapter spring 806, the connecting slide 805 will elastically fit on the leather surface, and cooperate with the driving motor 803 to drive the sliding connecting shaft 804 to rotate, so as to control the rotation of the wiping brush plate 807, and use the white cotton soft hair at the bottom to test the engraving position. If carbonization occurs, carbonized black particles will be attached to the white cotton soft hair. The staff can quickly observe the color of the bottom of the wiping brush plate 807 by turning the motor connecting seat 802 to make a judgment. During the formal cutting, the wiping brush plate 807 can be used for cleaning.
