Paper laminator and paper laminating method

Abstract

The invention relates to a device in the technical field of paper laminating production, specifically relates to a paper laminator and a paper laminating method. the paper laminator has the followingstructure: an electric heating tube is installed behind a laminating roll and a cooling roll is arranged in front of the electric heating tube; the electric heating tube is connected with a power source and is opposite to a raw paper route; a cooling roll shaft is arranged in the middle of the cooling roll; the cooling roll shaft is installed on a rack; an outlet of cold water and a recover port of hot water are connected to a circulation pipe; the cooling roll shaft is a structure with an air core therein; and the middle part of the circulation pipe is connected to the air core of the coolingroll shaft. According to the paper laminating method, raw paper is coated with a film by the laminator. The method is characterized in that the raw material is heated before the lamination so as to discharge moisture out of the raw paper and then the raw paper is cooled to room temperature for lamination. The method has the following advantages: wrinkles on the surface of the product after the lamination can be reduced, and the product quality can be improved.

Description

technical field [0001] The invention relates to equipment in the technical field of paper lamination production, in particular to a paper lamination machine and a paper lamination method. Background technique [0002] Paper lamination is the process of covering the raw material paper with a layer of film, and the paper after lamination improves the grade of the product. [0003] The raw material paper is a long strip of material paper that is coiled into a full roll. [0004] The lamination of raw material paper is carried out on the paper laminating machine. The paper laminating machine has a frame on which there are raw material rolls, transfer rolls, lamination rolls and finished product rolls. Raw material rolls, transfer rolls, lamination rolls and Finished rolls are arranged on the frame from back to front in turn, and the raw material paper is installed on the raw material roll, and finally wound on the finished roll through the transfer roll and the coating roll to ...

[0004] The lamination of raw material paper is carried out on the paper laminating machine. The paper laminating machine has a frame on which there are raw material rolls, transfer rolls, lamination rolls and finished product rolls. Raw material rolls, transfer rolls, lamination rolls and Finished rolls are arranged on the frame from back to front in turn, and the raw material paper is installed on the raw material roll, and finally wound on the finished roll through the transfer roll and the coating roll to complete the paper coating on the finished roll; in the prior art, the paper coating The machine does not have a part to heat the raw material paper, so the raw material paper is processed at room temperature, because there is still a certain amount of moisture in the raw material paper, it will affect the quality of the product, mainly manifested in the wrinkles on the coated product
