[0002] Laser cutting is to focus the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting.

[0003] The above-mentioned laser cutting equipment will generate smoke and dust during use. If the smoke and dust are not handled in time, it will affect the health of operators around the equipment. In the prior art, a dust collection device component is set in the above-mentioned laser cutting equipment, but the above-mentioned dust collection device component is generally installed independently and equipped with a moving component, and the position needs to be adjusted separately after the laser cutting head moves. Therefore, it is not so convenient to use. In order to improve it, a smoke and dust removal device for cutting production is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3A smoke and dust removal device for cutting production includes a laser cutting device 1 and an annular dust hood 4. The annular dust hood 4 is provided with a dust suction pipe 5, which is connected to components such as a dust suction pump. The annular dust hood 4 is arranged outside the laser cutting device 1 and is connected through a stabilizing mechanism. A connecting plate 2 is installed on the shell of the laser cutting device 1, and a connecting rod 3 is installed on the connecting plate 2. The connecting rod 3 is connected to a movable adjustment component in the cutting device to realize the multi-directional movable cutting operation of the laser cutting device 1. The above components are all existing technology products. In this scheme, the above existing technology products are not described in detail. For details, please refer to the prior art disclosure.

[0022] A driving motor 11 is provided on the shell of the laser cutting equipment 1 through a mounting mechanism, an inner gear ring 9 is provided on the upper end surface of the annular dust hood 4, the inner gear ring 9 is connected to the inner gear ring 9 through a rotating mechanism, an annular protective net 13 is installed at the bottom of the annular dust hood 4, a scraper 14 is installed on the laser cutting equipment 1, and a brush is installed on the scraper 14.

[0023] The stabilizing mechanism includes a vertical plate 6 arranged on the upper end surface of the annular dust hood 4, a limiting bolt 7 is threadedly installed on the vertical plate 6, a support block is provided at the end of the limiting bolt 7, and an annular groove 8 cooperating with the support block is opened on the shell of the laser cutting equipment 1. As the limiting bolt 7 rotates relative to the vertical plate 6, it can drive the support block into or away from the annular groove 8, thereby realizing the limiting or releasing operation of the annular dust hood 4.

[0024] The mounting mechanism includes a mounting plate 10 arranged on the shell of the laser cutting equipment 1, and the drive motor 11 is installed at the bottom of the mounting plate 10. The mounting plate 10 realizes stable support of the drive motor 11 and ensures the stability of the drive motor 11 when placed above the annular dust hood 4.

[0025] The rotating mechanism includes a gear 12 connected to the output shaft of the drive motor 11, and the gear 12 is meshed with the inner ring gear 9. The gear 12 cooperates with the inner ring gear 9 to realize the power transmission of the drive motor 11, and can realize the synchronous rotation operation of the annular dust hood 4 when the drive motor 11 rotates. The drive motor 11 in this scheme does not always rotate in one direction, but reciprocates forward and reverse to avoid the dust collection tube 5 from being entangled. How to realize the reciprocating forward and reverse rotation of the drive motor 11 is a prior art, and this scheme does not elaborate on the prior art.

[0026] The annular protective net 13 is made of stainless steel. The connecting plate 2 and the shell of the laser cutting equipment 1, the driving motor 11 and the mounting plate 10, and the scraper 14 and the shell of the laser cutting equipment 1 are connected by means of mounting bolts. The connection between the above-mentioned multiple components relies on mounting bolts to facilitate disassembly and assembly, thereby facilitating the inspection, maintenance and replacement of some components.

[0027] The vertical plate 6 and the annular dust hood 4, and the mounting plate 10 and the laser cutting device 1 are all welded together. The welding connection between the above-mentioned multiple components is to ensure the stability when the multiple components are connected.

[0028] When the utility model is used, smoke and dust are generated during the process of starting and cutting objects by the laser cutting device 1. The smoke and dust can be sucked away by the dust suction pipe 5 and the annular dust suction hood 4 and other components, thereby ensuring the air quality around the processing equipment.

[0029] As the above-mentioned equipment components are used for a long time, the mesh of the annular protective net 13 will inevitably be clogged, which will affect the dust collection effect. At this time, the drive motor 11 is started and rotated back and forth, so that the dust collection tube 5 becomes entangled. In this process, the drive motor 11 drives the gear 12 to rotate, and the gear 12 drives the annular dust hood 4 and the annular protective net 13 to rotate relative to the scraper 14 with the help of the inner ring 9, and cooperates with the brush on the scraper 14 to clean the mesh of the annular dust hood 4.

[0030] In this solution, with the help of mounting bolts, the drive motor 11 relative to the mounting plate, the laser cutting equipment 1 relative to the connecting plate 2, and the scraper 14 relative to the laser cutting equipment 1 are conveniently disassembled and assembled. By removing the limiting bolts 7, the limiting contact operation of the vertical plate 6 relative to the annular groove 8 is achieved, thereby realizing convenient disassembly and assembly of multiple components of the equipment, providing convenience for its inspection, maintenance or replacement.

[0031] The standard parts used in the utility model can all be purchased from the market, and the shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt the conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
