Description

Technical Field

[0001] The utility model relates to the technical field of PC board production, in particular to a production device for outdoor UV-resistant highly flame-retardant and cold-resistant PC boards. Background Art

[0002] PC sheet is a plastic sheet primarily composed of polycarbonate, also known as polycarbonate sheet or PC sheet. The production of highly flame-retardant, cold-resistant, UV-resistant PC sheets for outdoor use typically involves raw material cleaning equipment, mixing equipment, PC sheet extruders, and PC sheet laser cutters.

[0003] However, when the existing laser cutting machine cuts the PC board, due to the lack of an effective dust suction mechanism near the laser cutter of the laser cutting machine, the smoke and dust generated during the laser cutting machine cutting the PC board will fly into the air of the nearby workshop, affecting the quality of the working environment and thus affecting the health of the workers. Even if some existing laser cutting machines are equipped with a dust suction mechanism, the filter bag (filter screen) in the dust suction mechanism is easily covered with particulate matter after long-term use. In order not to affect the dust suction effect of the dust suction mechanism on the laser cutting machine, the debris on the surface of the filter bag must be cleaned. When cleaning the debris on the surface of the filter bag, the machine needs to be stopped for cleaning, which reduces the convenience of cleaning the debris on the surface of the filter bag.

The rotating driving column 407 drives the driving block 304 and the annular brush 301 to move back and forth, thereby cleaning away debris attached to the surface of the filter bag 207. Moreover, there is no need to stop the machine for cleaning when cleaning the debris on the surface of the filter bag 207.
