Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machine protective covers, and particularly relates to a laser cutting machine protective cover. Background Art

[0002] A laser cutting machine emits laser from a laser generator, which is focused into a laser beam with a high power density through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, a high-pressure gas coaxial with the beam blows away the melted or vaporized metal. Laser cutting uses an invisible beam to replace the traditional mechanical knife, with the characteristics of high precision, fast cutting, no limitation to cutting pattern, automatic layout to save materials, smooth cut, and low processing cost. It will gradually improve or replace the traditional metal cutting process equipment. When a laser cutting machine is in use, a protective cover is required for protection. After retrieval, the prior art (publication number: CN219520904U) records "a laser cutting machine protective cover, the technical solution of which includes: a protection box and a laser cutting machine. A motor is installed on one side of the inner top of the protection box. A lead screw is installed on the output shaft of the motor. A lifting seat is sleeved on the outer surface of the lead screw. A laser cutting machine is installed in the middle of the bottom of the lifting seat. Buffer plates are installed on both sides of the protection box through buffer rods. Springs are installed on the outer surface of the buffer rods at the gap position between the buffer plates and the protection box. Damping rubber is installed at the gap position between the buffer plates and the protection box." A laser cutting machine protective cover solves the problem that the existing protection device mainly protects the laser cutting machine through a pulling block, but there is a possibility of collision during the operation and loading of the laser cutting machine, and the buffer protection effect of the pulling block on the collision impact force is limited, and there is a risk of damage to the laser cutting machine, improving the anti-collision performance of the laser cutting machine and thus extending the service life of the laser cutting machine.

[0003] Although the laser cutting machine protective cover in the prior art achieves the anti-collision buffer protection effect, there are still some deficiencies: As is well known, when a laser cutting machine cuts different materials, fumes and dust will be generated. For example, when cutting metal materials, smoke will be generated, and some of the smoke contains harmful substances. Similarly, when cutting plastics, dust will be generated. Therefore, the protective cover in the prior art does not have the function of treating smoke and dust, and it is not convenient to clean the inner wall of the protective cover, resulting in poor use effects.

[0023] In this embodiment, the cover body 1, the soot treatment device 2, and the cleaning device 3 constitute the main body structure of the laser cutting machine protective cover involved in this application. Among them, in the Figure 2 cover body 1 structure shown in the drawings, the front side plate structure is omitted to facilitate showing the position of the first suction holes 14, and at the same time, the front side plate is set as a detachable connection.

[0024] Specifically, two of the side plates of the cover body 1 are made of a transparent high-temperature resistant material to facilitate observing the cutting state.

[0025] Specifically, the treatment box 25 is provided with a solvent treatment liquid that can achieve a neutralization reaction with the smoke generated by laser cutting metal, and the liquid level is not higher than the exhaust port 28 described below.

[0026] Specifically, a conical waterproof cover is provided on the outer side of the laser cutting machine main body 4 to prevent it from being contaminated by the cleaning agent during cleaning.

[0027] As Figure 3As shown in the figure, an inclined filter screen 23 is provided inside the dust suction box 21. The connection between the dust suction pipe 22 and the dust suction box 21 is located below the filter screen 23, and the connection between the air inlet pipe 26 and the dust suction box 21 is located above the filter screen 23. At the same time, a collection box 24 is provided below the filter screen 23. A suction fan 27 is installed in the pipeline of the air inlet pipe 26, and the lower end of the air inlet pipe 26 is connected to a guide pipe 29.

[0028] Specifically, a suction pump is provided above the filter screen 23 and at the top of the dust suction box 21, and the suction port of the suction pump is connected to the inside of the dust suction box 21 through a pipeline.

[0029] As a preferred embodiment, by providing the filter screen 23, it is convenient to separate smoke and dust, and realize the separate neutralization and purification treatment of smoke.

[0030] As Figure 1 and Figure 4 As shown in the figure, a water pump 32 and a hose 33 are connected to the lower side of the water tank 31. The lower end of the hose 33 is connected to the water distribution tray 341 included in the diversion assembly 34. The lower end of the water distribution tray 341 is connected to the sliding plate 345 through a diversion pipe 344. Cavities are provided inside both the water distribution tray 341 and the sliding plate 345. Connection holes 342 and through holes 343 are provided on the upper end surface of the water distribution tray 341. An electric push rod is connected inside the through hole 343, and the base of the electric push rod is fixed on the inner wall of the top of the cover 1.

Through the dust suction box, the dust suction pipe, the circulation cavity, the first suction hole and the second suction hole, harmful smoke and dust generated during the cutting process are suctioned. After the smoke enters the dust suction box, it is then sucked into the treatment box, enters the interior of the treatment box through the air guide pipe and reacts with the treatment liquid to achieve a purification effect, and then is discharged from the exhaust port. The dust settles downward under the action of the filter screen and falls into the collection box to achieve a collection effect. When cleaning is required, first turn off the main body of the laser cutting machine, and then start the water pump and the electric push rod, so that the water pump pumps the cleaning agent in the water tank into the diversion assembly, and then sprays it onto the inner wall of the cover body through the spray holes on the outer side of the sliding plate. At the same time, under the action of the guide rod and the guide hole, the electric push rod pushes the sliding plate to move up and down reciprocally, and then the inner wall of the cover body is cleaned by the wire brush on the outer side.

[0035] The laser cutting machine protective cover of the present utility model can effectively solve the problems that the laser cutting machine protective cover in the prior art does not have the function of treating smoke and dust, and at the same time is not convenient for cleaning the inner wall of the protective cover. On the basis of the existing laser cutting machine protective cover technology, it realizes the function of treating the smoke and dust generated during the laser cutting process, and has the function of cleaning the inner wall of the protective cover, increasing the practicability of the device.

[0036] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
