Embossing device of film blow-molding machine

Abstract

The invention relates to the field of film blow-molding machines, in particular to an embossing device of the film blow-molding machine. The embossing device involves a bottom plate and a plastic thinfilm, mounting plates are fixed to the two sides of the upper end face of the bottom plate, a rotating shaft is fixed between the two mounting plates, the rotating shaft is driven by a motor to rotate, a main traction roller allowing the rotating shaft to penetrate through is fixed to the rotating shaft, a supporting shaft is further fixed at the position, on one side of the rotating shaft, between the two mounting plates, a supporting roller allowing the supporting shaft to penetrate through and fixedly connected with the supporting shaft is fixed to the supporting shaft, the two ends of thesupporting shaft are connected with the mounting plates through sliding mechanisms I, the sliding mechanisms I comprise sliding grooves I transversely formed in the mounting plates, a plurality of sliding rails I are transversely fixed in each sliding groove I, sliding blocks I connected with the sliding rails I in a sliding mode are further fixed in the sliding grooves I, the tail end of the supporting shaft penetrates through the sliding blocks I and is rotationally connected with the sliding blocks I, and the sliding blocks I are fixedly connected with piston rods of air cylinders I whichare transversely fixed. By means of the embossing device, natural switching of thin film printing can be achieved.

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...
