Problems solved by technology

[0003] The blown film is rewound by passive friction in the past. Due to the generated film roll ribs, the deflection of the reel is not neat, and the edge sealing gaps during bag making, etc., resulting in great waste.

Abstract

The invention discloses a blown film winding device in automatic correction. The blown film winding device in automatic correction comprises a rack which is of an arch-shaped structure, and inclined side plates are symmetrically installed on the two sides of the rack; a film entering roller is connected to one of the side plates through a bearing pedestal, and a film discharging roller is connected to the other side plate through a bearing pedestal; a screw is movably connected to the rack; the upper end of the screw is connected with the lower plane of a balance plate through a bearing; the left side of the balance plate is connected with a film leading roller through a bearing; and a correction roller is installed on the right side of the balance plate. The blown film winding device in automatic correction is compact in structure, reasonable in design thought, novel and unique; in the blown film winding process, it is guaranteed that a blown film is wound more orderly by means of correction, rib exposing is reduced, bag making before opening printing is facilitated, opening materials for use can be reduced, and meanwhile cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of film processing machinery, in particular to a blown film winding device with automatic deviation correction. Background technique [0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The manufacturing process of blown film is very similar in principle to blow molding of hollow products, but it does not use molds. From the perspective of plastic processing technology classification, the forming process of blown film is usually included in extrusion. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. Blown film process flow, plasticizing and extruding materials to form tubes and blowing molding; cooling, pulling, and coiling. [0003] The blown film is rewound by passive friction in the past. Due to the generated film roll ribs, the deflection of t...
