Laminating machine can be divided into coating type and precoating type. It is a kind of special equipment for paper, board and film mounting. After being pressurized by rubber roller and heating drum, it forms a paper plastic product. It is used to complete the film covering process. Generally speaking, it can be divided into coating and pre coating according to the process used, and it can be divided into bright film and Matt film according to different thin film materials.
Problems and solutions of laminating machine in laminating process.
1、Crinkle paper

1. The tensile force of the film is large, resulting in fold marks and vertical wrinkles. Adjust the film tightness.

2. The film itself is uneven and wrinkled. Adjust the film transfer rod.

3. The pressure is too high and the temperature is too high. Adjust the pressure and temperature.
4. The rubber pressure bar is deformed. Remove the pressure bar and grind it again.
5 wet paper, keep the working environment and paper dry or use drying in laminating.
2、Crinkle membrane
1. If the temperature is too high, properly reduce the temperature and pressure, and adjust the required temperature of various membranes
Adjust the balance of the rod into the membrane.
3. If the film is stacked too long, replace the film.
4. Film tension is too large or too small, adjust the film tightness 3: there are snowflakes on the product.
(1) Excessive dusting of printed matter, remove the dusting on the printed matter before laminating.
(2) The pressure of pressure roller is not suitable. The solution is to adjust the pressure of pressure roller correctly.
(3) The temperature is too low, adjust to the appropriate temperature 4: bubble appears.
The precoating laminating machine is composed of four main parts: unwinding of precoated plastic film, automatic input of printed matter, lamination of hot pressing area and automatic winding up, as well as auxiliary devices such as mechanical transmission, flattening of pre coated plastic film, vertical and horizontal slitting and computer control system. The automatic conveying mechanism can ensure that the printed matter does not overlap and enter the composite part equidistant in the transmission. Generally, pneumatic or friction mode is adopted to realize the control. The conveying accuracy and precision are high. The above requirements can also be met when the printing materials with small size are compounded.
