[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-3 , the utility model provides an embodiment: a laser cutting head with exhaust gas collection function, including a laser emitter body 1, a nozzle 2 is provided on the bottom side of the laser emitter body 1, and the slide rails 6 are fixedly connected to the left and right sides of the laser emitter body 1 respectively, and the sliding sleeves 5 are fixedly connected to the adjacent sides of the two connecting frames 4, and the sliding sleeves 5 are slidably connected to the outer wall of the slide rails 6. The front side of the rack 9 fixedly connected to the front side of the connecting frame 4 is meshed with a gear 8. The non-driving end of the double-headed motor 7 located on the front side of the laser emitter body 1 is fixedly connected to the front side of the laser emitter body 1 through a fixed frame. The two driving ends of the double-headed motor 7 are fixedly connected to the middle end of the gear 8. The bottom sides of the two connecting frames 4 are fixedly connected to a frame 3, and the surroundings of the frame 3 are fixedly connected to transparent glass plates;

[0026] Specifically, the laser transmitter body 1 is used to emit lasers for cutting. The transparent glass plates arranged around the frame 3 can form a space for preventing the exhaust gas from drifting, thereby limiting the exhaust gas while utilizing the transparent characteristics to not hinder the cutting process. When performing laser cutting, the laser transmitter body 1 uses the nozzle 2 to cut. At this time, the two driving ends of the double-headed motor 7 drive the gear 8 to rotate, and then the gear 8 drives the rack 9, so that the rack 9 drives the connecting frame 4 to move. At this time, the sliding sleeve 5 slides on the slide rail 6, so that the frame 3 and the transparent glass plate connected to the connecting frame 4 are lowered, covering the cutting area, preventing the exhaust gas generated during cutting from diffusing, and when not cutting, the frame 3 and the transparent glass plate are raised to maintain the laser cutting head.

[0027] Reference Figure 3 and Figure 4 The top rear end of the frame 3 is fixedly connected with a housing 10, two cavities are provided inside the housing 10, a collecting fan 13 is installed at the output end of the cavity, a filter plate 12 is provided on the inner wall of the cavity, and a connecting pipe 11 is fixedly connected to the output end of the cavity;

[0028] Specifically, the filter plate 12 can filter the exhaust gas passing through the cavity, and the filter plate 12 can be disassembled and replaced. The connecting pipe 11 is used to connect to an external collection pipe for collecting exhaust gas. The collecting fan 13 is located in the space formed by multiple transparent glass plates to attract the exhaust gas. By starting the collecting fan 13 in the shell 10 to collect the exhaust gas in the transparent glass plate, the exhaust gas enters the cavity through the collecting fan 13 and is guided to the connecting pipe 11 connected to the external collection pipe at the output end of the cavity. During this period, the exhaust gas passes through the filter plate 12 in the cavity, and can be preliminarily filtered.

[0029] Reference Figure 1 , Figure 5 and Figure 6 The specifications of the multiple clamps 14 fixedly connected to the top of the nozzle 2 and the multiple clamping grooves opened on the outer periphery of the bottom end of the laser emitter body 1 correspond to each other, and the inside of the clamping groove is fixedly connected with an abutting inclined plate 15, and the top of the clamp 14 is clamped on the top side of the outer periphery of the bottom end of the laser emitter body 1, and the outer periphery of the abutting inclined plate 15 abuts against the inner periphery of the clamp 14;

[0030] Specifically, the clamp 14 has a certain elasticity, and the outer surface of the abutting inclined plate 15 has a certain curvature. When the clamp 14 abuts against the abutting inclined plate 15, it will deform along the arc on the abutting inclined plate 15. When installing the nozzle 2, by inserting the clamp 14 on the nozzle 2 into the slot from the bottom side, when the clamp 14 abuts against the abutting inclined plate 15, the clamp 14 will be offset to the periphery and deformed, and the nozzle 2 will continue to be pushed upward. When the top end of the clamp 14 reaches the top side of the outer periphery of the bottom end of the laser emitter body 1, it will be reset and stuck on the top side of the outer periphery of the bottom end of the laser emitter body 1, so that the new nozzle 2 is installed on the laser emitter body 1.

[0031] Working principle: When performing laser cutting, the laser transmitter body 1 uses the nozzle 2 to cut. At this time, the two driving ends of the double-headed motor 7 drive the gear 8 to rotate, and then the gear 8 drives the rack 9, so that the rack 9 drives the connecting frame 4 to move. At this time, the sliding sleeve 5 slides on the slide rail 6, so that the frame 3 connected to the connecting frame 4 and the transparent glass plate are lowered, covering the cutting area to prevent the exhaust gas generated during cutting from diffusing, and starting the collecting fan 13 in the shell 10 to collect the exhaust gas in the transparent glass plate, so that the exhaust gas enters the cavity through the collecting fan 13, and is guided to the connecting pipe 11 connected to the external collection pipe at the output end of the cavity. During the process, it passes through the filter plate 12 in the cavity, which can perform preliminary filtration on the exhaust gas. When replacing the nozzle 2, force is applied to the top side of the clamp 14 to deform it, and the nozzle 2 is pulled downward to disengage the clamp 14 from the slot, thereby disengaging the nozzle head from the laser emitter body 1. Subsequently, a new nozzle 2 is installed, and the clamp 14 on the nozzle 2 is inserted into the slot from the bottom side. When the clamp 14 abuts against the abutting inclined plate 15, the clamp 14 will be offset to the periphery and deformed, and the nozzle 2 will continue to be pushed upward. When the top end of the clamp 14 reaches the top side of the outer periphery of the bottom end of the laser emitter body 1, it will be reset and stuck on the top side of the outer periphery of the bottom end of the laser emitter body 1, thereby installing the new nozzle 2 on the laser emitter body 1.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
