Plastic film water removal device and method

Abstract

The invention discloses a plastic film water removal device and method. The device comprises a guide roller set, a water scraping plate set and a drying unit, a plastic film passes through the guide roller set, the water scraping plate set and the drying unit in sequence, the guide roller set, the water scraping plate set and the drying unit are fixedly connected to a rack and electrically connected with a numerical control unit, the guide roller set presses and guides the upper surface and the lower surface of the conveyed plastic film under the control of the numerical control unit, a vacuum cavity communicating with a vacuum pump is formed in the guide roller set, the vacuum pump is electrically connected with the numerical control unit, a plurality of adsorption holes communicating with the vacuum cavity are formed in the guide roller set at intervals in a penetrating mode, and the surface of the guide roller set is coated with a water absorption sponge layer. A width adjusting unit used for adjusting the width of the water scraping plate set is arranged on the water scraping plate set, and the numerical control unit controls the width adjusting unit to adjust the width of the water scraping plate set so as to effectively remove water from plastic films with different widths.

Description

technical field [0001] The invention relates to the technical field of plastic film water removal, in particular to a plastic film water removal device and method. Background technique [0002] The flat wire is formed by the wire drawing machine by heating, extruding, cutting, stretching and winding the raw material. After the raw material is extruded, it is formed into a plastic film in the pool. In the plastic flat wire drawing production process, the plastic film after the water bath It also contains a large amount of water, which needs to be dried before entering the subsequent processing technology. The existing plastic film water removal device uses two scrapers to remove water from the plastic film, and the two scrapers are respectively set on the plastic film. The water removal effect is poor at the upper and lower surfaces; and the existing plastic film water removal devices cannot remove water from plastic films of different widths and thicknesses, which has strong...

[0002] The flat wire is formed by the wire drawing machine by heating, extruding, cutting, stretching and winding the raw material. After the raw material is extruded, it is formed into a plastic film in the pool. In the plastic flat wire drawing production process, the plastic film after the water bath It also contains a large amount of water, which needs to be dried before entering the subsequent processing technology. The existing plastic film water removal device uses two scrapers to remove water from the plastic film, and the two scrapers are respectively set on the plastic film. The water removal effect is poor at the upper and lower surfaces; and the existing plastic film water removal devices cannot remove water from plastic films of different widths and thicknesses, which has strong limitations and cannot be widely used; the existing plastic film water removal devices Generally, the absorbent cotton of the device cannot be reused after absorbing the moisture on the surface of the plastic film, and the absorbent cotton needs to be replaced, which is very time-consuming and laborious
