Abstract

The invention discloses a heat shrinkage film take-up device. The heat shrinkage film take-up device comprises a frame, driving gears and a first rack, wherein a take-up shaft is arranged on the frame; one end of the take-up shaft is rotationally connected with the frame, and the other end of the take-up shaft is a cantilevered end; a film roll with axial freedom sleeves the take-up shaft; a compression roller with vertical freedom only is arranged above the take-up shaft; a vertically upward second rack is arranged at the upper end of the compression roller; the second rack comprises a toothed part and a non-toothed part positioned at the lower end of the toothed part; the driving gears mesh with the toothed part; the first rack is horizontally arranged on the side surface of the take-up shaft; a transmission mechanism capable for converting circular motion of the driving gears into horizontal motion of the second rack is arranged on the frame; a limiting buckle allowing the first rack to penetrate is arranged on the frame; a first elastic piece is arranged between the limiting buckle and the end, close to the side of the take-up shaft, of the first rack; and the first rack can be driven by the first elastic piece to push the film roll out of the take-up shaft. By adoption of the scheme, the problem that automatic unrolling cannot be finished in the prior art can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic film processing, and in particular relates to a heat-shrinkable film winding device. Background technique [0002] In the film production line, the auxiliary equipment that winds the produced film on the paper core to form a roll is called a winder or a coiler. [0003] During the winding process of the film, the cooperation of the pressure roller and the winding roller is usually required to timely discharge the air in the film roll and flatten the film surface so as to achieve the purpose of dense film roll and smooth film surface. At present, the commonly used winding devices for heat shrinkable films are generally used in conjunction with a pressure roller and a winding roller up and down. By applying a certain pressure on the pressure roller, the pressure roller is closely attached to the winding roller to achieve The purpose of exhaust flattening. Considering the effect of friction a...
