Polymer plastic film device

Abstract

The invention belongs to the technical field of film treatment, in particular to a polymer plastic film device which comprises a base, self-adaptive mechanisms, roller mechanisms, a first roller and afirst roller shaft. the first roller shaft and the two roller mechanisms are arranged between the two self-adaptive mechanisms symmetrically arranged on two sides of the base; and the first roller isnested onto the first roller shaft. According to a polymer plastic film wrinkle removing device provided by the invention, the two self-adaptive mechanisms are matched with the two roller mechanisms,and a wrinkle part on a unilaterally deformed plastic film moved from the first roller and supported and pulled by the upwarp end of the tilted roller during the conveying process is self-adaptivelytightened so as to be at the tightening state again, so that the wrinkle caused by unilateral deformation of the film is effectively removed or reduced, preparation is made for the next corona processof the plastic film, and the qualification rate of the plastic film finished products is effectively improved.

[0002] At present, plastic film products are widely used in all aspects of life and production. To make the surface of polyvinyl chloride products smooth and smooth, first of all, it is necessary to ensure that the surface of polyvinyl chloride film is smooth and wrinkle-free before the production of plastic film products; The method of removing wrinkles is to use corona to smooth the surface of the plastic film processing equipment, but this kind of equipment cannot guarantee that the surface of the material is still in a flat state when it is fed into the corona step; the result may be: due to a certain or Some rollers are skewed due to long-term wear and tear, and are likely to be rolled into rolls and squeezed into folds layer by layer. The folds include the entire fold along the width direction or because of the skewed roll The plastic film is deformed on one side and local wrinkles on one side are caused by one end falling and one end upwarping; during the secondary processing of the film pulled out from the roll, such as corona, the entire fold is easily pulled due to the pulling force It does not have much impact on the later process; however, because the non-wrinkled side bears most of the tensile force on one side of the local folds, it is extremely difficult to stretch the local folds, and the effect of corona treatment on the partially wrinkled plastic film is very good. poor, which in turn affects the pass rate of the final plastic film product after corona, which in turn leads to economic losses for the enterprise
