A heat shrinkable film folding device

Abstract

The invention discloses a folding device for a heat shrinkable film. Through the arrangement of a first conveying roller, a triangular folding frame, a guide part and a second conveying roller, the first conveying roller can convey the heat shrinkable film which needs to be folded to the triangular folding frame. The heat shrinkable film is moved from top to bottom on the triangle folding frame, is folded in half after being guided by the guide part and is conveyed by the second conveying roller, and the folding work is completed. Through the arrangement of a guide rail, a moving member and athin film sensor, the thin film sensor can be driven to move by the movement of the moving member on the guide rail, so that the thin film sensor measures the width and position of the heat shrinkablefilm. A controller adjusts the position of an adjusting rod on a second bracket according to the measurement results, thereby driving the tip of the triangle folding frame to move to enable the triangular folding frame to be matched with the widths and positions of different heat shrinkable films. The universality of the folding device is improved.

Description

technical field [0001] The invention relates to the technical field of heat shrinkable film preparation, in particular to a heat shrinkable film folding device. Background technique [0002] In the process of preparing heat shrinkable film, different specifications of heat shrinkable film have different widths. In order to facilitate transportation, many plastic film manufacturers first manually fold the produced plastic film, and then wind it into a narrower paper tube, etc. components to solve the above problems, but this method is more labor-intensive; [0003] In this regard, the Chinese utility model patent CN201520411113.0 proposes a film doubler and a film multi-stage doubler, which folds the film in half through a triangular folding frame, which can also be used for heat shrinkable film folding, but the device can only Folding a heat-shrinkable film of one width in half has poor versatility. Contents of the invention [0004] In view of this, the object of the pr...
