Dust collecting and dust preventing device for powder spraying machine

Abstract

The invention relates to a dust-collecting and dust-proof device for a powder spraying machine; the technical solution thereof includes a box body, a powder spreader that can evenly sprinkle powder into the box body is arranged above the box body, and the left and right sides of the box body are respectively There is a rectangular slot, and a baffle plate is hinged at the upper and lower ends of each slot. The two baffle plates keep vertical shape without external force and block the corresponding slot. The slot is blocked by two blocks. When the board is sealed, there is a gap between the two baffles for the passage of the PVC calendered transparent film. There is a drawer-type dust collection box on the front and rear sides of the lower end of the box. The opening of the dust collection box is upward and the bottom is equipped with a heating wire. There are multiple vertical through holes evenly distributed on the four side walls of the dust collecting box. There is a suction hood at the bottom of the box. A plurality of ventilation passages communicate with the vertical through holes and the suction hood.

Description

Technical field [0001] The present invention relates to the field of PVC transparent transparent film production, particularly dust-proofing devices for a polishing machine. Background technique [0002] During the production of PVC transparent membrane, in order to prevent surface sticking, sprayed with sticky powder, commonly known as flour, there is a special set of devices, ie flooding machine, flooding machine in surface flour, very fine powder The particulate matter is atomized by the high voltage line of the flooding machine, spreading into the surface of the film, because the powder is very thin, very light, when you are afraid of very weak airflow, you will fall around, on the one hand, pollute the surrounding environment and equipment, on the other hand, It is naturally slippeted to a certain degree of flour to a certain extent, falling in the surface of the film to a certain extent, which is not allowed. Inventive content [0003] In order to overcome the deficiencies...

AI Technical Summary

Problems solved by technology

[0002] In the production process of PVC calendered transparent film, in order to prevent the surface from sticking dirty, anti-sticking powder is sprayed on the surface, commonly known as dusting. There is a set of special equipment, that is, powdering machine. The particles are atomized by the high-voltage line of the powder spreader and scattered on the surface of the membrane. Because the powder is very fine and light, it will fall everywhere when it encounters even a weak airflow. On the one hand, it will pollute the surrounding environment and equipment, and on the other hand, it will cause In addition to uneven powdering, the powder on the surface of the equipment on the membrane will naturally slide to a certain extent and fall on the surface of the membrane to form large spots, which are not allowed
