[0002] Laser engraving machine, as the name implies, is an advanced equipment that uses laser to engrave the materials that need to be engraved. Laser engraving machine is different from mechanical engraving machine and other traditional manual engraving methods. Mechanical engraving machine uses mechanical means, such as diamond and other extremely hard materials to engrave other things; while laser engraving machine uses the heat energy of laser to engrave materials, and the laser in the laser engraving machine is its core. Generally speaking, the scope of use of laser engraving machine is wider, and the engraving accuracy is higher and the engraving speed is faster. Moreover, compared with the traditional manual engraving method, laser engraving can also achieve very delicate engraving effect, which is no less than the craftsmanship level of manual engraving. Smoke and dust will be generated during laser engraving, and then a smoke exhaust device is needed. The filter plate of the existing smoke exhaust device is easily blocked by smoke and dust during use, affecting the operation of the device. Utility Model Content

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] During work, the operator places the dust hopper on the engraving equipment, and then starts the vacuum pump to absorb the smoke and dust engraved by the engraving equipment into the interior of the mounting table, and at the same time starts the air pump to blow the smoke and dust entering the mounting table into the interior of the device body. After the smoke and dust enter the interior of the device body, they are filtered through two filters. At the same time, the operator starts the servo motor to drive one of the sprockets to rotate.

When the installation frame and the filter net move up and down quickly, the smoke on the filter net can be shaken to avoid clogging of the filter net. The smoke dust filtered by the filter net will enter the interior of the activated carbon for adsorption and purification. The purified smoke dust is discharged through the smoke outlet pipe. When the smoke dust on the filter net accumulates a lot, the operator can open the sealing door to clean the filter net; the filter net of the device will not be blocked by smoke dust during use, and the smoke dust can pass normally, thereby ensuring the normal operation of the device.
