Equipment for pvc film processing

Abstract

The invention discloses an apparatus used for processing a PVC membrane. The apparatus comprises an upper frame, a lower frame, and a first spreading member and a second spreading member rotatably disposed between the upper and lower frames; the upper frame is provided with a first feeding member that is matched with the first spreading member and a second feeding member that is matched with the second spreading member, and a corona device for generating a corona to flatten the material is arranged at a lower portion of the first spreading member; a connecting seat is arranged at a lateral part of the upper frame, and a cylinder is arranged at the lower frame; the connecting seat is detachably connected to the upper frame, and a hand-operated adjusting device used for adjusting a relativedistance of the connecting seat and the upper frame is arranged at the upper frame. The connecting seat and the upper frame are detachably connected, when maintenance operation is carried out, a spacebetween the upper and lower frames exceeds a motion stroke of the cylinder, the connection of the connecting seat and the upper frame is released, the relative position between the upper and lower frames is adjusted through the hand-operated adjusting device, and the enough distance between the upper and lower frames can be guaranteed for maintenance for operators.

Description

technical field [0001] The invention belongs to the technical field of polyvinyl chloride processing, and in particular relates to a device for processing PVC films. 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. In order to solve the above problems, a device for leveling and feeding the PVC film has appeared in the prior art, and the material is fed by a feeding roller, and then the material is leveled by corona. The traditional PVC film leveling device is composed of upper and lower frames, and the relative position between the two frames is adjusted by lifting or lowering the ...

Problems solved by technology

[0005] Secondly, a corona device is set up, which can emit corona or arc when energized to iron the PVC film, thereby ensuring the good flatness of the PVC film, and not only effectively solving the problem in the process of PVC film processing. In the case of wrinkles, 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 and makes the performance of the PVC film more excellent in the later use; and when the PVC film When it is necessary to stick transparent film or paper, etc., the glue coating on the surface of PVC film can be more uniform, so that the adhesion with transparent film or paper can be stronger, and the product qualification rate and service life can be improved; and through the first display The setting of the first piece and the second material display piece 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 product qualification rate
