Description

Laser cutting dust collector

Technical Field

The utility model belongs to the technical field of dust collectors, and in particular relates to a laser cutting dust collector.

Background Art

The laser cutting machine focuses the laser 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. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. During the cutting process, metal components will produce a large amount of metal dust and irritating gases. If they remain in the workshop, they will easily affect the health of employees.

A Chinese patent document with application number 2019222616752 discloses a laser cutting dust collector, including a cutting machine moving mechanism, a negative pressure box is fixedly connected to the top of the cutting machine moving mechanism, a bellows is fixedly connected to the side of the negative pressure box close to the cutting machine, the bellows is connected to the interior of the negative pressure box, a number of connecting plates are fixedly connected at equal distances on both sides of the tube wall of the bellows, a spring is fixedly connected between two adjacent connecting plates, and a dust suction pipe is fixedly connected to the end of the bellows away from the negative pressure box.

The advantage of the above solution is that the vacuum tube can be extended as the laser cutting machine moves. However, like the prior art, the dust in the gas is sucked from the top. The defect of this solution is that the dust is easily diffused to the airflow dead corners in the surrounding area during the rising process, resulting in incomplete dust removal effect.

Example 1

As shown in Fig. 1-2, a laser cutting dust collector includes a base 1, a workbench 2 and an upper cover 3. The base 1, the workbench 2 and the upper cover 3 are arranged in sequence from bottom to top. A working area 4 is provided in the middle of the workbench 2. The working area 4 is used to place the workpiece to be cut. A laser cutter 18 is provided above the working area 4. The purpose of this scheme is to extract the dust generated by the laser cutter 18 after the work. The laser cutter 18 is installed in a cubic mounting seat 19. The bottom of the mounting seat 19 is an open structure. The laser cutter 18 emits laser downward to laser cut the workpiece to be cut on the working area 4. The side of the mounting seat 19 is connected to the X-axis direction and the Y-axis direction slide rail mechanism, which is used to drive the mounting seat 19 and the laser cutter 18 to move. The laser cutter 18 and the X-axis direction and the Y-axis direction slide rail mechanism are all well-known technologies in the art. Any model on the market can be selected. Its specific principle and structure will not be repeated in this embodiment.

A blower mechanism is provided at the front end of the upper part of the workbench 2, and a negative pressure mechanism is provided at the rear end of the upper part of the workbench 2. The blower mechanism includes a blower 5 and a wind plate 6. The blower 5 is located at the front end of the base 1. The wind plate 6 is provided with a plurality of blow ports 7, which are arranged facing the working area 4. The blower 5 is connected with a blow pipe 8, which is connected with the plurality of blow ports 7 in the wind plate 6. The negative pressure mechanism includes a negative pressure plate 9 and a first negative pressure pump 10. The negative pressure plate 9 is provided with a negative pressure groove 11 facing the working area 4. The first negative pressure pump 10 is connected with a negative pressure pipe 12, which is connected with the negative pressure groove 11 on the negative pressure plate 9. The wind plate 6 and the negative pressure plate 9 are located at the front and rear sides of the working area 4. The airflow is blown from the blow port 7 to the working area 4 by the blower 5, and then the negative pressure is provided from the rear end of the working area 4 by the first negative pressure pump 10 and the negative pressure groove 11. The cross section of the negative pressure groove 11 is trumpet-shaped, and the trumpet-shaped cross section can increase the cross-sectional area of the groove to a certain extent, thereby increasing the suction efficiency of the negative pressure mechanism. A larger cross-sectional area can provide a larger space, making it easier for air to be drawn into the negative pressure system, thereby improving the suction efficiency. Through the design of the trumpet-shaped cross section, the speed of the air in the cross section can also be reduced, the noise generated when the air flows can be reduced, the comfort of the working environment can be improved, and noise pollution can be reduced. The front-end blowing mechanism and the rear-end negative pressure mechanism can more centrally suck the dust generated in the working area 4 where the cutting operation is performed. In this way, the dust in the cutting area can be more effectively controlled and cleaned, the possibility of dust diffusion can be reduced, and the generated dust can be cleaned more quickly and thoroughly, which helps to improve the efficiency of the entire dust removal system, reduce the dust concentration in the air, and reduce potential safety risks. By quickly sucking the dust generated laterally, the dust can also be effectively prevented from depositing on the surface of the working area 4. This helps to maintain the cleanliness of the cutting machine equipment, reduce the frequency of equipment maintenance and cleaning, and thus reduce pollution to the surrounding environment. A filter screen 23 is provided in both the first negative pressure pump 10 and the second negative pressure pump 17, and the filter screen 23 plate adsorbs the dust in the gas and discharges qualified gas.

A work plate 13 is provided on the work area 4, and the workpiece to be cut is placed on the work plate 13. A through dust collecting hole 14 is provided on the work plate 13. A dust collecting chamber 15 is provided below the work plate 13. The dust collecting chamber 15 is located in the base 1. A dust collecting pipe 16 is provided at the bottom of the dust collecting chamber 15. The dust collecting pipe 16 is connected to a second negative pressure pump 17. After the second negative pressure pump 17 is working, the dust collecting chamber 15 will also generate negative pressure, and the dust on the work plate 13 will be sucked from the bottom, which can better prevent the dust from spreading and prevent the dust from accumulating and affecting the quality of laser cutting. This helps to keep the cutting tool clean, reduce interference during the cutting process, and improve the processing quality of the product.

Example 2

This embodiment has the same parts as the embodiment 1. In this embodiment, a dust removal plate 20 is provided at the bottom of the mounting seat 19, a dust removal chamber 21 is provided in the middle of the dust removal plate 20, and a dust removal pipe 22 is connected to the side of the dust removal chamber 21. The dust removal pipe 22 is connected to the first negative pressure pump 10. Since the dust removal plate 20 and the through dust removal chamber 21 are directly located at the bottom of the laser cutter 18, this arrangement can more centrally suck the dust generated by laser cutting and improve the local suction effect. It can also reduce the spread of dust in the working area 4, which helps prevent dust from entering other equipment or space.

A physical barrier can be formed at the bottom of the laser cutter 18 through the dust removal plate 20 and the through dust removal chamber 21 to prevent dust from falling directly on the surface of the laser cutter 18, thereby effectively protecting the operating parts of the laser cutter 18 and extending the life of the equipment.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
