Precoating laminating machine for preventing curling

Abstract

The invention discloses a pre-coating film machine for preventing curling, which includes a carton, a paper roll, a transmission plate, a smoothing roll, a dehumidification pressure roll, a film roll, a guide roll, a heat press roll, a fan, a protruding shaft, a traction shaft, Cold pressure roller, this invention solves the problem of retroperitoneal paper curling caused by existing laminating machines. According to the reason of curling due to paper humidity and one-sided laminating pressure, a dehumidification pressure roller is arranged in the laminating machine. The paper is dehumidified, and on the other hand, it provides a certain pressure on the paper to be coated, so that the paper is dry and compact before the coating. A fan and a convex shaft are installed inside the laminating machine. The fan cools the paper after the coating is hot-pressed. The reciprocating rotation of the cam shaft exerts reverse pressure on the paper, and a cold pressure roller is installed at the exit of the laminating machine to shape the paper and ensure the paper is flat.

Description

technical field [0001] The invention relates to the field of film processing, in particular to a pre-coating film machine for preventing curling. Background technique [0002] The laminating machine can be divided into two categories: instant coating laminating machine and pre-coating laminating machine. It is a special equipment for paper and film. The ready-to-coat laminating machine includes three parts: gluing, drying, and hot pressing. It has a wide range of applications and stable and reliable processing performance. It is currently the most widely used laminating equipment in China. Pre-coating laminating machine, without gluing and drying parts, small size, low cost, flexible and convenient operation, not only suitable for lamination processing of large batches of printed matter, but also suitable for lamination of small batches of scattered printed matter such as automated desktop office systems Processing has great development prospects, that is, the operation of...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a pre-coating laminating machine that prevents curling. This invention solves the problem of paper curling in the retroperitoneum caused by existing laminating machines. There is a dehumidification pressure roller in the laminating machine, which dehumidifies the paper on the one hand, and provides a certain pressure on the paper to be coated on the other hand, so that the paper is dry and compact before laminating. There are fans and convex rollers inside the laminating machine. The shaft and the fan cool down the paper after hot-pressing the film, and the reciprocating rotation of the cam shaft exerts reverse pressure on the paper. There is a cold pressure roller at the exit of the laminating machine to shape the paper and ensure the flatness of the paper.

[0005] Further illustrate, the present invention dehumidifies the paper that is about to be covered with a dehumidification pressure roller, a fan and a protruding shaft are arranged between the hot pressing roller and the cold pressure roller, the fan cools the paper after hot pressing, and the protruding shaft The reverse force is applied to the paper after lamination and hot pressing to solve the curling problem of one-side lamination. The invention is equipped with a driving motor, a switch control system, and a gear transmission system.
