Conveying structure for plastic packaging paper printing

Abstract

The invention provides a conveying structure for plastic packaging paper printing, and relates to the technical field of conveying structures.The conveying structure comprises a connecting base, a screw is mounted at one end of a screw mounting frame, one end of an abutting block is fixedly connected with a warming plate mounting frame, and a warming plate is fixedly mounted on the upper surface of the warming plate mounting frame; the heating plate is located below the paper body, the upper surface, close to the driving roller, of the paper body is provided with an edge warping prevention assembly, the edge warping prevention assembly comprises a connecting wheel and a pin rod, the lower surface of the connecting wheel is in rolling connection with the upper surface of the edge of the paper body, and the lower end of the pin rod abuts against the bottom wall of the abutting hole. Through the arrangement of the warming plate, the paper body is moderately heated in an auxiliary mode so that the paper body can be soft, the edge of the paper body is pressed in a rolling mode through the connecting wheel on the edge warping prevention assembly so that the paper body can be smooth as much as possible, warping edges are prevented from being pressed into creases by the driving roller, the next printing work is better guaranteed, and the paper clamping situation of the printing machine is reduced.

Description

technical field [0001] The invention relates to the technical field of conveying structures, in particular to a conveying structure for printing plastic wrapping paper. Background technique [0002] Plastic wrapping paper is a kind of packaging bag that uses plastic as raw material to produce various supplies in daily life. It is widely used in daily life and industrial production. The commonly used plastic wrapping paper is mostly made of granular plastic. After melting in an ultra-high temperature environment, it is processed and shaped by a plastic wrapping paper processing device, and then the preliminary plastic wrapping paper is obtained through winding of the paper tube. In the subsequent processing of the plastic wrapping paper, it needs to be printed to make its surface have Various graphics for better sales and more exquisite product packaging; [0003] Usually, during the printing process of plastic wrapping paper, the rewound plastic wrapping paper will be drive...

Problems solved by technology

[0005] In view of the prior art plastic wrapping paper in an environment with relatively low temperature, the edge of the plastic wrapping paper will be warped. At the same time, as the plastic wrapping paper continues to move, the warping of the edge of the plastic wrapping paper will not be suppressed in time, which will cause the plastic wrapping paper to warp. The edge warping is getting more and more serious, and finally the warping edge reaches the driving wheel, and the pressure of the driving wheel will cause irreversible creases on the plastic packaging paper, which will cause paper jams in the printing machine and affect the next printing work. , the invention provides a transport structure for plastic packaging paper printing
