Flattening machine for PVC film processing

Abstract

The invention discloses a flattening machine for PVC film processing. The flattening machine structurally comprises a box body, a lower clamping roller, an outlet, an upper clamping roller, a tensioning structure, a supporting wheel, an unwinding roller, a box door, power assisting structures and a transmission device; an outlet is formed in the left upper part of the box; the upper clamping roller is mounted in the box body and arranged in the side surface of the outlet; the lower clamping roller is arranged under the upper clamping roller; the supporting wheel is arranged in the middle of the box door; the unwinding roller is arranged in the right side of the box; the box door is arranged in the right side of the box body; the two power assisting structures are arranged at the two ends of the unwinding roller correspondingly; the two ends of the unwinding roller are installed on the two power assisting structures correspondingly; and the power assisting structures are movably connected with the transmission device. The flattening machine has the advantages that when the weight of a whole roll of film is too large, a power assisting device can be pressed down to enable the unwinding roller and the lower clamping roller to rotate synchronously through the transmission device, so that the film does not need to be pulled, the film is prevented from being damaged, and proper tensioning can be conducted through the tensioning structure.

Description

technical field [0001] The invention relates to the field of film processing equipment, in particular to a flattening machine used for PVC film processing. Background technique [0002] The production and processing process of PVC film usually includes material selection, mixing, molding, winding and other links, and according to the needs of customers or on-site production activities, the PVC film needs to be unfolded for secondary processing. [0003] A roll of PVC film has a large weight, and the PVC film itself is relatively thin. When pulling, the PVC film is pulled to drive the whole bundle of film to anti-roll. The weight of the whole bundle of film will pull the PVC film, making the PVC film excessively stretched Deformation, easy to cause damage to the PVC film. Contents of the invention [0004] The main purpose of the present invention is to overcome the deficiencies of the prior art and provide a flattening machine for PVC film processing. [0005] The presen...
