Dust removing device used on filming coating machine base cloth before coating

Abstract

The invention provides a dust removing device used on a filming coating machine base cloth before coating, and belongs to the field of base cloth dust removing devices. The dust removing device comprises a lower air suction pipe, a water channel, a brush roller, a guide roller, an air suction nozzle, fans and dust removing bags. The guide roller is provided with a driving mechanism, the guide roller is connected with the driving mechanism, the brush roller is installed at the same horizontal position as the guide roller and is parallel to the guide roller, the brush roller is tangent to the guide roller, the air suction nozzle is vertically installed, the bottom end of the air suction nozzle is located at the position wherein the guide roller is tangent to the brush roller, the top end of the air suction nozzle is connected to an air exhaust opening of the fan A through a pipeline, the water channel is arranged below the brush roller, the bottom end of the brush roller is arranged in the water channel, the lower air suction pipe is arranged below the water channel and connected to an air exhaust opening of the fan B through a pipeline, an air channel is formed in the lower air suction pipe, and the air exhaust opening of the fan A and the air exhaust opening of the fan B are connected with the dust removing bags respectively. According to the dust removing device used on the filming coating machine base cloth before coating, dust on the base cloth can be removed thoroughly, and secondary pollution, caused by static electricity, of the base cloth cannot be generated.

Description

technical field [0001] The invention provides a dust removal device before coating a base cloth of a film coating machine, which belongs to the field of base cloth dust removal devices. Background technique [0002] With the diversified production requirements of plastic container bag products, the quality requirements of some of them are getting higher and higher. To meet the needs of some high-end customers, for some coated film products, foreign matter treatment before coating is an important link. The traditional coating is only a brush roller and a fan attached to the equipment. After the brush roller scrapes the dust on the base fabric, it is sucked away by the fan. However, due to the power of the fan and the effect of the upward suction, plus the Static electricity during coating adsorbs dust, and dust removal often cannot be cleaned thoroughly. [0003] The technical defect at present is: one, the dust and sundries stained on the brush roller will contaminate the b...

[0002] With the diversified production requirements of plastic container bag products, the quality requirements of some of them are getting higher and higher. To meet the needs of some high-end customers, for some coated film products, foreign matter treatment before coating is an important link. The traditional coating is only a brush roller and a fan attached to the equipment. After the brush roller scrapes the dust on the base fabric, it is sucked away by the fan. However, due to the power of the fan and the effect of the upward suction, plus the Dust is adsorbed by static electricity during coating, and dust removal often cannot be cleaned thoroughly

[0003] At present, the defects of this technology are: firstly, the dust and sundries stained on the brush roller will contaminate the conveying base cloth again due to static electricity; secondly, the base cloth cannot be cleaned thoroughly before coating
