Problems solved by technology

[0003] When the existing laminating machine is laminating, there are two main ways to heat the heating roller, one is to set the electric heating element in the heating roller, and the other is to set the heating roller as hollow, and the heat conducting Oil and other heat-conducting media; the heating method of setting electric heating elements in the heating roller is prone to the problem of uneven heating; the method of setting the heating roller as hollow and feeding heat-conducting oil basically solves the problem of uneven heating, but this It is not only necessary to heat the heat conduction oil by means of electric heating, but also to use an oil pump to continuously circulate the heating oil, which increases the consumption of electric energy. Now there is an urgent need for a method that can improve the heating uniformity of the heating roller and Does not raise heating rollers on electrical energy consumption

Embodiment

[0049] Embodiment: a kind of laminating machine for precoating film production, see attached figure 1 And attached figure 2 , including a frame 1 supported on the ground, a coating roller 2 rotatably connected to the frame 1, a pre-coating film roller 3 rotatably connected to the frame 1, a heating pipe rotatably connected to the frame 1 and a rotating Two extrusion rollers 5 connected on the frame 1. Specifically, the paper to be coated is wound on the coating roll 2, and a pre-coating film is wound on the outside of the pre-coating film roll 3, and the pre-coating film is pasted around the heating roll 4 and then bonded to the paper. The precoat film is attached to the outside of the heating roller 4 when it is wound around the heating roller 4 .

[0050] When carrying out paper coating, the paper to be coated is wound on the outside of the coating roll 2, the pre-coating film is wound on the outside of the pre-coating film roll 3, and then the paper and the pre-coating f...

Abstract

The invention discloses a film laminating machine for pre-coating film production, and relates to the technical field of paper film laminating, and the technical scheme is characterized in that the film laminating machine comprises a rack, a film laminating roller, a pre-coating film roller, a heating roller and an extrusion roller; the heating roller comprises a rotating roller which is rotationally connected to the rack; the heating sleeve is arranged on the outer side of the rotating roller in a sleeving mode and fixedly connected with the rotating roller, a containing cavity is formed in the inner side of the heating sleeve, and a liquid heat-conducting medium is injected into the containing cavity; an electric heating element is arranged in the rotating roller; a heat conduction rod is fixed to the outer side of the electric heating element, and the end, away from the electric heating element, of the heat conduction rod penetrates through the rotating roller and extends into the containing cavity. The electric heating element transfers heat into the liquid heat-conducting medium of the containing cavity, and then the heat is uniformly transferred to the heating sleeve through the liquid heat-conducting medium, so that the pre-coating film is more uniformly heated by the heating sleeve, a pump does not need to be additionally arranged for liquid circulation, and the consumption of electric energy does not need to be increased.

Description

technical field [0001] The invention relates to the technical field of paper lamination, more specifically, it relates to a laminating machine for pre-coating film production. Background technique [0002] Pre-coating film lamination is a method of laminating paper. When laminating, use a pre-coating film laminating machine to achieve it; the glue coated on the pre-coating film is hot melt adhesive. When laminating First, the pre-coating film is heated by the heating roller to make the glue on the pre-coating film play a sticky role, and then the pre-coating film and the paper are pressed together by two pressure rollers to realize the lamination of the paper. [0003] When the existing laminating machine is laminating, there are two main ways to heat the heating roller, one is to set the electric heating element in the heating roller, and the other is to set the heating roller as hollow, and the heat conducting Oil and other heat-conducting media; the heating method of set...
