Stability of the quality of the flat pasting machine
Precoating laminating machine is a special equipment flat pasting machine that combines printed matter with precoated plastic. Compared with the instant coating laminating machine, its biggest feature is that there is no glue coating and drying part. Therefore, this kind of laminating machine has the advantages of compact structure, small volume, low cost and simple operation

Good product quality and stability.
The precoating laminating machine is composed of four main parts: uncoiling of precoated plastic film, automatic input of printed matter, hot pressing zone compounding and automatic winding, as well as auxiliary devices such as mechanical transmission, leveling of precoated plastic film, vertical and horizontal slitting, computer control system and so on.
1. The automatic conveying mechanism of the printed matter input part can ensure that the printed matter does not overlap during transmission and enters the composite part equidistantly. Generally, it is controlled by pneumatic or friction, and the conveying is accurate and high precision. When the printed matter with small composite format can also meet the above requirements.
2. The composite part includes composite roller group and calendering roller group. The compound roller group is composed of silica gel heating pressure roller and pressure roller. The thermal pressure roller is a hollow roller with a heating device inside. The surface is forged with hard chromium, polished and finely ground; The temperature of hot pressing roller is tracked and sampled by sensor and corrected by computer at any time; The adjustment of compound pressure adopts eccentric cam mechanism, and the pressure can be adjusted steplessly. The calendering roller group is basically the same as the composite roller group, that is, it is composed of chrome plated pressure roller and silica gel pressure roller, but there is no heating device. The main function of the calendering roller group is: after the precoated plastic film is combined with the printed matter by the composite roller group, the surface brightness is not high, and then the surface brightness and bonding strength are greatly improved by the secondary extrusion of the calendering roller group.
3. Transmission system the transmission system is driven by the high-power motor controlled by the computer. After the first gear is decelerated, it drives the movement of the paper feeding mechanism and the rotation of the composite part and the silicone pressure roller of the calendering mechanism through the three-stage chain drive. The pressure roller group maintains appropriate working pressure under the action of stepless adjustment pressure.
4. Computer control system the flat pasting machine computer control system adopts microprocessor, and the hardware configuration is composed of host board, digital key board, optical isolation board, power supply board, stepping motor power drive board, etc.
