Film coating machine can be divided into coating machine and precoating machine. It is a kind of equipment used for paper kind, thin film special equipment. That is, the coating coating machine includes glue, drying, hot pressure three parts, its application range is wide, stable and reliable processing performance, is widely used domestic coating equipment. Pre-coating film machine, no glue and dry part, small volume, low cost, flexible and convenient operation, not only suitable for large batch of printing film processing, but also suitable for automatic desktop office system and other small batch, scattered printing film processing, very promising film machine is divided into three glue, drying channel, hot pressure parts:
1. Rubber glue. The rubber part is equipped with an adjustment device to adjust the amount of rubber on it, to meet the requirements of different seals, and the rubber roller adopts rubber roller or steel roller.
2. The drying channel section. The oven path is generally long: 2? 3m. The drying crossing of the film adding is equipped with infrared lamp tube and electric fan. The upper part of the automatic film mulching machine dryer also has an electric heating pipe and an exhaust fan with high power. The temperature can be adjusted to dry the adhesive and eliminate the exhaust gas.
3. Hot pressure part. This part is the key to coating, directly related to the bond fastness of coating products. The principle of thermal pressure is that the adhesive can quickly infiltrate and penetrate into the surface layer of the seal in the melting state, thus obtaining a solid binding interface layer. The hot pressure part consists of a set of rollers. One of the hollow metal drum, equipped with an electric heat pipe, the temperature can be automatically controlled. This set of drum pressure can be adjusted.
