A blown film machine embossing device

Abstract

The invention relates to the field of film blowing machines, in particular to an embossing device for a film blowing machine, which includes a base plate and a plastic film, mounting plates are fixed on both sides of the end surface of the base plate, and a rotating shaft is fixed between the two mounting plates. The rotating shaft is driven by a motor to rotate, and the main traction roller through which the rotating shaft passes is fixed on the rotating shaft. A support shaft is also fixed between the two mounting plates on one side of the rotating shaft, and a supporting shaft is fixed on the supporting shaft to pass through and A support roller fixedly connected to the support shaft, both ends of the support shaft are connected to the mounting plate through a sliding mechanism I, the sliding mechanism I includes a chute I arranged transversely on the mounting plate, and the chute I is horizontally fixed There are a plurality of sliding rails I, and a sliding block I slidingly connected with the aforementioned sliding rail I is fixed in the sliding groove I, and the end of the support shaft passes through the sliding block I and is rotationally connected with the sliding block I, and the sliding block I is fixedly connected with the piston rod of the horizontally fixed cylinder I. The device can realize the natural switching of film printing.

Description

【Technical field】 [0001] The invention relates to the field of film blowing machines, in particular to an embossing device for a film blowing machine. 【Background technique】 [0002] The film blowing machine heats and melts plastic particles and blows them into films. The film blowing machine mainly includes a screw extrusion mechanism, a die head, a cooling mechanism, a traction mechanism and a winding mechanism. [0003] In the small batch production process of film embossing, the hemp roller acts on the plastic film to form raised pits and patterns required by customers. When processing films of different specifications and models, it is necessary to replace the hemp roller at the tail. Traditional The replacement method needs to disassemble the cylinder and the rubber roller above it after stopping the machine, and then replace the hemp roller. The replacement work is time-consuming and labor-intensive, and the work efficiency is low. [0004] The present invention res...
