Embodiment 1

[0044] Embodiment one is basically as attached Figure 1 to Figure 5 Shown:

[0045] The laser cutting machine dust removal device includes a cabinet body 1 with a cabinet door 11 installed on it. The cabinet body 1 includes an air extraction chamber 12, a dust removal chamber 13 and a dust collection chamber 14 separated from each other by a partition from top to bottom. The body 1 is provided with an air suction port (communicating with the dust collection chamber 14) and an air outlet 15 (communicating with the air extraction chamber 12), and the air suction port can be externally connected with the air suction pipe 2.

[0046] There are five dust removal bags 3 in the dust removal chamber 13 (the dust removal bags 3 have their own filter holes). The dust removal bags 3 are filter bags with a support frame. The bag 3 is fixedly clamped on the communication hole on the top of the dust collection chamber 14, and the blower fan 4 is fixed in the pumping chamber 12 by screws;

Embodiment 2

[0060] Embodiment two is basically as attached Figure 6 As shown, the second embodiment has the following improvements on the basis of the first embodiment: an elastic member 10 is connected between the bottom of the collection box 8 and the bottom of the cabinet 1, the elastic member 10 adopts a spring, and an alarm is installed on the cabinet 1. The alarm is connected with a button switch 20, and the button switch 20 is fixed on the cabinet 1 at the bottom of the collection box 8 by screws.

[0061] The specific implementation process is as follows:

[0062] As the dust in the collection box 8 continues to increase, the collection box 8 overcomes the elastic force of the elastic member 10 (that is, the spring) and moves downward until the dust collected in the collection box 8 is heavy enough to press down on the button switch 20, thereby triggering an alarm. The device reports to the police, is convenient for the workman to replace collecting box 8 in time after hearing t...

Embodiment 3

[0065] Embodiment three is basically as attached Figure 7 As shown, embodiment three has been improved on the basis of embodiment two, specifically as follows: a purification unit is also installed in the dust removal chamber 13, the purification unit includes an unwinding roller 30 and a winding roller 40, and the winding roller 40 is connected by an external Driven by a motor, the unwinding roller 30 is wound with several successively connected active carbon bags 60 (that is, the active carbon bags 60 are connected into a strip, and then the strip-shaped active carbon bags 60 are wound on the unwinding roller 30), and the The winding roller 40 can rewind the activated carbon pack 60 unwound from the unwinding roller 30; the cabinet 1 where the dust removal chamber 13 is located is rotatably connected with several guide rollers 50, and several connected activated carbon packs 60 wind around the guide roller 50 The back is wavy; the activated carbon bag 60 is located between ...

Abstract

The invention relates to the technical field of dust removal equipment, and specifically discloses a dust removal device for a laser cutting machine, which includes a cabinet body. A cleaning unit, the cleaning unit includes a moving part, a first magnet, a cleaning brush and a driving part, a sliding bar is arranged in the dust removal bag, the first magnet can move axially along the sliding bar, the cleaning brush is connected with the first magnet, and the cleaning brush is connected with the first magnet. The first magnet moves synchronously, and the cleaning brush can be offset against the inner surface of the dust bag; the moving part is located outside the dust bag, and the moving part is provided with a second magnet that attracts the first magnetic block, and the driving part drives the moving part to move. The magnets move synchronously with the moving parts. In this solution, a cleaning unit is provided to solve the problem in the prior art that the filter bags of the dust removal device are easily covered with dust and block the filter holes, so that the dust removal device cannot work normally.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a dust removal device for a laser cutting machine. Background technique [0002] Laser cutting is to irradiate the workpiece with a high-power-density laser beam, so that the irradiated material is rapidly melted and vaporized, and at the same time, the high-speed airflow coaxial with the beam blows off the molten material, thereby realizing the cutting of the workpiece. [0003] In laser vaporization cutting, under the heating of high-power-density laser beam, about 40% of the material is vaporized into steam and disappears, and 60% of the material is blown away by the auxiliary gas from the bottom of the slit as ejecta, and is mixed with fine particles in the air. Combine to form dust. In laser melting cutting, when the power density of the incident laser beam exceeds a certain value, the material at the irradiated area begins to evaporate to form holes, while t...
