Flattening device for PVC film processing

Abstract

The invention discloses a flattening device for PVC film processing. The flattening device comprises an upper rack, a lower rack, a first material spreading component and a second material spreading component, wherein the first material spreading component and the second material spreading component are arranged between the upper rack and the lower rack in a rotatable manner, wherein a first material conveying component which conveys materials through the cooperation of the first material spreading component and a second material conveying component which conveys materials through the cooperation of the second material spreading component are arranged on the upper rack, and the lower part of the first material spreading component is provided with an electric corona device used for producing electric corona so as to flatten materials. In the flattening device provided by the invention, by arranging the electric corona device which can send out electric corona or electric arcs when beingelectrified, ironing treatment on a PVC film is carried out, the good flatness of the PVC film is ensured, the condition that the PVC film has creases in the processing process is effectively solved,the uneven places of the PVC film also can be fully ironed flatly in a material forming period, the flatness of the PVC film is improved to an utmost degree, and the performance of the PVC film during later use period is better.

Description

technical field [0001] The invention belongs to the technical field of polyvinyl chloride processing, and in particular relates to a leveling device for PVC film processing. Background technique [0002] With the development of the times, PVC film is gradually winning people's favor with its good performance, simple process and many other advantages, and has been accepted and recognized by more and more people. The darling of PVC film can be seen everywhere in people's daily life. Due to the small thickness of the PVC film, wrinkles often appear during the manufacturing process, which affects the later use effect. But there is no equipment that can well solve the wrinkle of PVC film in the prior art. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a leveling device for PVC film processing that can effectively avoid wrinkles during PVC film processing. [0004] In order to achieve the above object,...

Problems solved by technology

In the present invention, a corona device is provided, and the corona device can emit corona or electric arc to iron the PVC film when it is energized, thereby ensuring the good flatness of the PVC film, and not only effectively solving the problem in the PVC film processing process In the case of wrinkles in the middle, it can also completely iron out the unevenness of the PVC film during the material forming process, which greatly improves the flatness of the PVC film, making the performance of the PVC film more excellent in the later use; and when the PVC film When the film needs to be covered with transparent film or paper, etc., the glue coated on the surface of the PVC film can be more uniform, so that the adhesion with the transparent film or paper can be stronger, and the product qualification rate and service life can be improved; and through the first exhibition The setting of the material part and the second material display part can effectively flatten the material sent between the upper and lower racks, avoiding the wrinkle of the material during the conveying process and the situation that it cannot be ironed by the corona, and improving the quality of the product.
