Laminating machine use principle

1. Use the film as the cover to protect the paper. After the film is coated, the service life of the cover (or the surface of the printed product) can be extended, especially for the students' textbooks, so the usage is getting larger and larger;

2. The print marks are not easily damaged. After coating with a film, it can add color effect and protection to the color printed graphic without wearing it, which is beneficial to the publishers on the surface of the cover or printed product according to their needs. Various art designs have also contributed to the increase in usage;

3, that is, the production of coating film is large, the cost of film coating in the film is low, easy to get on, and profitable, the enterprise can benefit.

Laminator troubleshooting

First, the machine does not start: the input wire is not connected, the power cable is reversed, and the voltage is not enough;Second, the temperature measurement 【Hand Lamination Machine 】is not accurate: thermocouple, temperature controller. Whether the installation is incorrect and damaged;Third, the working vacuum does not come: the gas path is not connected, the hand valve or the solenoid valve is not closed, the vacuum pump motor belt is loose, and the vacuum gauge is damaged;Fourth, the main power switch trip: heating box top input wire leakage, distribution box leakage, external wires on the equipment, motor leakage, etc.;The film is not in place: the vacuum is not enough, the gas is leaking, the temperature is not enough, the film is too thin, the workpiece is pasted by other materials, the concave depth of the workpiece exceeds the film pull-up, the suction time is too short, the film is not pulled up, the workpiece distance too close.

Sixth, the surface of the workpiece is folded and not smooth or the corners are not covered: the film is not straightened, the film quality is not good, the workpiece is not well polished, the glue is sprayed too much, and the mold under the workpiece is too low.【 Film Lamination Machine 】When the suction is not applied, the film pulls down: whether the solenoid valve or the hand valve is open;Seven, play the phenomenon: the temperature is too high, the heating time is too long, the film quality is not good, no heating;Eight, the situation of sticking to the board is not good.

The ways to laminate the film

The coating process can be divided into cold (cold pressure) coating, hot (heating) coating and liquid coating according to the heat, pressure and material. Thermal coating technology refers to heating and pre-coating the adhesive on the diaphragm, through which the film is bonded to the printed product; while the cold coating is pressed, directly bonding the film to the printed product by the adhesive. Together. Both methods can produce various special films such as UV protective film, waterproof or anti-friction film. Recently, there has also been a new technology called "liquid film". Simply use a brush, spray gun, roller or special laminator to apply a film directly on the surface of the product. Although the technical operation is simple and the price is low, it is still not mature.

Small laminating machine laminating process. This type of small laminator was developed to meet the needs of low-to-medium consumers.【Automatic Laminator】This kind of small laminating machine solves the fundamental problem of the ordinary laminating machine. The price of the laminating machine is between 1400 and 1500 yuan. Since the film is pressed by the inner hot rubber roller, the film is heated up and down, which increases the heating time of the precoating film, and It is heated and balanced, so the film that is covered is smooth and bright, and it has the same effect as the film coated by the high-grade laminating machine. Only such a small laminating machine has a heating power of only 500 W. Although the temperature is adjustable, the speed is fixed, and the film can be pressed 0.7-0.8 m per minute. Suitable for business card lamination, recipe film, photo film and graphic print film, especially for small printing houses, typing and copying shops, business card production companies and photo studios.【Film Lamination Machine】In order to reduce equipment investment and reduce costs, this type of film is used. There are more machines.At present, the market prospects of such small laminating machines are very good. Many customers who used to use them have later started sales of such laminating machines, and the sales volume is also good. It can be said that this small laminating machine is the most cost-effective. It is easy to use and has obvious effects. It solves the needs of some small end customers and has a great promotion value.

How to properly store white glue ?

                                 
                                Thermal Lamination Machine


01
Store before opening
Avoid glue exposure, rain (will reduce glue storage time, reduce stickiness)
Keep the room temperature at 15-25 degrees Celsius (storage temperature below 8 degrees Celsius will reduce the glue adhesion, below 4 degrees Celsius will lose the viscosity of the glue).

02 
Stored after opening
Do not infiltrate other substances into the glue bucket, otherwise local clumping, discoloration and deterioration will occur. [ Automatic Thermal Lamination Machine ] There is no need to add water to adjust the quality, and the addition of water will reduce the bonding strength of the glue, so the paste effect will not be achieved. Seal the plastic bucket and plastic bag immediately after use according to the amount until the next time you use it again. 

03
Storage after use
Clean the rubber bucket and plastic bag mouth and seal them intact, so as to prevent the dry film of glue remaining in the mouth of the barrel or the bag from falling into the glue, thus causing granulation. If it is not sealed, the glue will peel.
The pumping pump is immediately pumped into clean water to avoid accumulation of residue and gelation after solidification, which may cause blockage and affect production and use.

How to solve the wrinkle problems occurred in the film while the film laminating machine was working ?

Film Laminating Machine

How to solve wrinkles in the Film Laminating Machine , wrinkles in the film, in fact, this problem is widespread, and because of this, the problem of wrinkling of the film has become a problem that has been discussed in the post-press processing industry. Wrinkles appear in the film. How to solve it?

The reasons and solutions for the wrinkling of the Film Laminating Machine are as follows:

1. Vertical wrinkles.
 The film pull is too large, the pressure is not flattened, and there is a crease in itself, so wrinkles are formed after the film is finished.
Solution: Relax the film tension, adjust the spreader roll, and flatten the film before pressing.

2. Oblique wrinkles.
The film has large pulling force and improper adjustment of the roller position, resulting in inconsistent tightness of the film itself, uneven film transfer, and regular folding to the loose side.
Solution: Relax the film tension, adjust the stretch roll or temporarily change the film.

3. Horizontal wrinkles.
When the temperature of the heating roller is too high, the pressure of the rubber roller is too large, and the film is laterally creased into a lateral wrinkle when compounded.
Solution: Reduce the roll temperature or reduce the pressure of the rubber roller.
