Description

Technical Field

[0001] The utility model relates to the field of engraving machines, in particular to a dust removal device for engraving machines. Background Art

[0002] CNC engraving machines will generate a lot of dust when engraving on materials such as stone and metal. At the same time, as the engraving proceeds, a large amount of extremely fine debris particles will float on the surface of the material. Long-term inhalation of granular dust by workers can easily cause respiratory infections and other diseases. Therefore, a dust removal device is needed to remove the dust.

[0003] The dust removal device used in the operation of the existing engraving machine is generally set on one side of the equipment to absorb the smoke and dust dispersed around the engraving machine. However, the distance between this dust removal device and the cutter head of the engraving machine is too long, and the cutter head of the engraving machine is always in a moving state. The place where the smoke and dust are generated is also constantly changing. The existing dust removal device cannot effectively and timely absorb the smoke and dust generated by the engraving cutter head.

[0004] Therefore, in view of the fact that the existing engraving machine dust removal device is difficult to timely and effectively absorb and eliminate the smoke and dust generated by the moving engraving tool head, a dust removal device mounted on the engraving machine body can be designed, which moves with the engraving tool head and simultaneously sucks and eliminates the generated smoke and dust in two directions. Utility Model Content

[0005] In order to overcome the problem that the existing engraving machine dust removal device is difficult to timely and effectively absorb and eliminate the smoke and dust generated by the moving engraving tool head.

[0007] Preferably, the engraving machine's moving beam moves along the engraving platform, and at the same time, the engraving tool head moves along the moving beam to form a cross-shaped moving network on the material for engraving. While engraving, the external dust extraction fan is started to form a negative pressure in the No. 1 dust extraction component and the No. 2 dust extraction component to suck out the smoke and dust generated near the engraving tool head. After engraving is completed, the engraving tool head is put away, and the No. 1 dust extraction component and the No. 2 dust extraction component are controlled to fall until the brush rests on the surface of the engraving material. The moving beam moves back and forth, and the brush removes the debris on the surface of the material.

The external dust extraction fan draws air flow to form a negative pressure in the air inlet panel, carrying smoke and dust into the air inlet panel from the air inlet grille, and finally intercepted in the dust filter bin.

[0009] Preferably, the No. 2 dust extraction component includes an air inlet pipe and an air inlet port; the air inlet pipe is a hollow U-shaped pipe fitting and the elbow portion is fixedly connected to the air inlet panel, and 8-12 air inlets facing the air inlet grille are equidistantly arranged on the straight portion of the air inlet pipe. An external dust extraction fan draws air flow, forming a negative pressure in the channel formed by the air inlet panel and the air inlet pipe, carrying smoke and dust from the air inlet port into the air inlet pipe, flowing along the air inlet pipe to the air inlet panel, and finally being intercepted in the dust filter bin.

[0010] Preferably, the brush is fixedly installed at the lower end of the straight part of the air inlet duct, and the end of the brush rests on the upper surface of the platform of the engraving machine. After the engraving is completed, the No. 1 dust extraction component and the No. 2 dust extraction component move obliquely downward at the same time until the brush contacts the surface of the material, and the debris generated by the engraving is removed along the surface of the material by the drive of the moving beam.

[0011] Preferably, two auxiliary lights are respectively fixedly mounted on the elbow of the air inlet duct, and the auxiliary lights illuminate the engraving tool head of the engraving machine. During the engraving process, the auxiliary lights are always on to illuminate the engraving tool head, making it easier for the operator to observe.

[0012] Preferably, a cylinder is fixedly mounted on the bracket, and brackets are fixedly connected to the left and right ends of the air inlet panel. The brackets are fixedly connected to the piston rod of the cylinder. The cylinder drives the bracket to move obliquely to control the adjustment position of the air inlet panel and the air inlet pipe. When engraving, the two are controlled to be on both sides of the engraving head, so that the engraving head moves up and down between the air inlet panel and the air inlet pipe to perform engraving operations. After engraving is completed, the cylinder controls the bracket to move obliquely downward and fall to the bottom of the movable beam, so that the brush is close to the engraving platform.

[0013] Preferably, a motor is installed on the side wall of the base, and a pin shaft rotatably connected to the base is provided on the bracket, the pin shaft is fixedly connected to the adjacent motor drive shaft, and the motor controls the bracket to drive the air inlet panel and the air inlet pipe to rotate.

[0016] 2. With the help of the brush on the No. 2 dust removal component, after engraving, the dust on the surface of the material can be cleaned by driving the cylinder and the motor in conjunction with the movement of the mobile beam of the engraving machine. It can also be cleaned during the dust removal process, which is flexible to use;
