The pre-coating film is a special one in the laminating process. In addition to the many advantages of the laminating process, it also increases the visibility function of the product in the packaging. The colorful printing patterns are embedded with beautiful curves. The viewing window not only makes the packaging more exquisite, but also plays the role of propagating and beautifying the commodity and revealing the value of the commodity, which has become an effective means to realize and increase the value of the commodity. The difference between its laminating principle and general laminating machine lies in:
1. It coats the adhesive on the surface of the film, and then covers the film on the surface of the printed product, and then presses it into the finished product;
2. The special advantage of the pre-coated film is that it can be automatically sprayed and can be automatically removed by heating and dissolving the powder by using the viscosity of the glue.
The pre-coated film process does not require a binder heating and drying system for the film coating equipment. It is easy to operate and can be turned on at any time. It has large production flexibility, no solvent odor, no environmental pollution, and more importantly, it can completely avoid bubbles and delamination. In case of failure, the transparency of the finished product is extremely high.

1. Trouble shooting of small laminating machine
Now when we operate a small laminating machine, we often see some cases where the machine cannot be started. Then, at this time, we need to test the entire power supply. First, we need to see whether the power supply is connected. If the connection is not good, then it is impossible to start. In addition, when we check whether the power supply is connected, we also need to pay attention to our power cable connection error. This is also a problem that many people often encounter, but, All of them appear at the first startup. If the situation does not start after a long time of use, then this problem will generally not appear. Finally, when the small laminating machine cannot start, we need to detect whether the voltage of the power supply is enough, because the small laminating machine is a machine with relatively large power consumption, and there are certain requirements for the voltage in the process of use. So we need to safely check whether the voltage meets the standard.
2. Temperature control of small laminating machine
In the working process of small laminating machines, it is often the case that the temperature detection is inaccurate, that is to say, we will have some work failures due to temperature errors during the operation, and the high and low temperatures will affect our Normal use makes our entire work in trouble. Therefore, we need to strictly check whether the temperature controller has a fault when the temperature is inaccurate. Once a fault occurs, it needs to be repaired in time, so that we can use it. More relaxed.
The common troubleshooting of small laminating machine is introduced here for everyone, I hope to help you.

Thermal laminating machine can be divided into two major categories of instant coating laminating machine and pre-coating laminating machine. The instant coating laminating machine includes three parts: gluing, drying and hot pressing. It has a wide range of application and stable and reliable processing performance. It is a pre-coating laminating machine widely used in China at present. There is no gluing and drying part, and the volume is small. , Low cost, flexible and convenient operation, not only suitable for laminating processing of large quantities of printed products, but also suitable for laminating processing of small batches and scattered printed products such as automated desktop office systems, which has great development prospects.
The laminating process is a surface processing process after printing. It is also known as post-press lamination, post-press laminating or post-press laminating. It refers to using a laminating machine to cover a layer of 0.012～0.020mm on the surface of the printed product. The thick transparent plastic film forms a paper-plastic integration product processing technology. The laminating machine is the equipment used to complete the laminating process. Generally speaking, it can be divided into two types: instant coating film and pre-coating film according to the process used, and two kinds of bright film and matte film according to the different film materials.

1. Equipped with a non-stop paper feeder to ensure continuous production.
2. The use of large-diameter pressing rollers effectively improves the production speed and ensures that the composite products are smooth and bright.
3. A powder removing mechanism combining powder sweeping and powder pressing is adopted to ensure the powder removing effect. (Configure powder removal device)
4. The advanced drying tunnel structure ensures that the glue on the film can be dried quickly.
5. Adjustable speed disc-type rotary cutter to ensure the slitting of paper.
6. The motor adopts frequency conversion control, safe and reliable.

1. When the machine of the small laminating machine is running, prevent fingers from entering the two rollers to avoid sticking hands. The temperature of the pressing roller of the machine is high. Do not touch with your hands to avoid burns. The machine should be turned on at a low speed when scrubbing the machine. To prevent the cloth in the hands of the two rollers from being crushed.
2. Glue, thinner, and washing machine are flammable. Pay attention to the fire hazard around the machine.
3. When using the thermocouple to detect the temperature of the sensing element of the temperature controller, it is greatly affected by the position of the device, the surrounding air temperature and the external wind flow, and the accuracy of temperature measurement has a large error. The temperature meter guides The temperature is an absolute temperature, the user should choose the temperature according to the practical processing experience and the reference value of the reference temperature table.
4. The machine used by the new device should be smooth to the machine, and pay attention not to use the machine quickly during the running-in period of the machine transmission.
5. The small laminating machine strictly prevents listening to any tools, devices and debris on the machine. The task air gap of the rubber roller and the rubber roller is extremely small. Once any hard object is pressed into the surface of the rubber roller, it is on the rubber Leaving depressions or cracks. The lighter ones need a longer time to recover from the natural elasticity, the heavy ones indirectly make the rubber rollers scrapped.
6. The main power switch of the machine should be closed when repairing and inspecting the machine. The electrical system of the machine should maintain good insulation to avoid moisture. When the machine is stalled, the power supply should be cut off to prevent accidents.
7. The hydraulic system must be unloaded during shutdown, when the pressure roller and the rubber roller are separated and the scraper and the pre-pressure roller are released, so as to avoid the temporary deformation of the two rollers due to pressure.
