Description

Technical Field

[0001] The utility model relates to the technical field of plastic products, in particular to a dust removal device for processing plastic films. Background Art

[0002] Agricultural film is a general term for plastic film used in agricultural production. It plays a very important role in moisture retention and heat preservation during the sowing period. With the advancement of science and technology, the requirements for agricultural film are getting higher and higher. In the process of plastic film processing, dust removal of plastic film is essential, which requires the use of dust removal equipment.

[0003] Common dust removal devices for plastic film processing usually use an exhaust fan to absorb dust on the surface of the film while the film is being rolled up. However, a small amount of dust will adhere to the film, which results in poor dust removal effect of the dust removal device for plastic film processing. At the same time, common dust removal devices for plastic film processing directly rewind the dust-removed film, which results in the film being not smooth after rewinding, thus affecting the rewinding effect of the dust removal device for plastic film processing.
