The Automatic Laminating Machine is a special equipment for compounding printed matter with pre-coated plastic. Compared with the instant coating type laminating machine, its biggest feature is that there is no glue coating and drying part, so this type of laminating machine has compact structure, small size, low cost, simple operation and good product quality stability.
Automatic Laminating Machine
The Pre-Coating Type Laminating Machine consists of four main parts: pre-coated plastic film unwinding, automatic printing of printed matter, hot press zone compounding, and automatic winding, as well as mechanical transmission, pre-coated plastic film flattening, vertical and horizontal slitting, and computer control system And other auxiliary devices.
1.The printed matter input section. The automatic conveying mechanism can ensure that the printed matter does not overlap and enter the composite part equidistantly during transmission. Generally, pneumatic or frictional control is used to realize the control. The conveying is accurate and high-precision. It can also meet the above requirements when the printed matter is composited with a small format.
2. Composite part. The composite part includes a composite roller group and a calender roller group. The composite roller group is composed of pressure roller and pressure roller heated by silica gel. The hot pressure roller is a hollow roller with a heating device inside. The surface is forged with hard chrome, polished and finely ground. The temperature of the hot pressure roller is tracked and sampled by a sensor and corrected by the computer at any time. The compound pressure is adjusted by an eccentric cam mechanism. Can be steplessly adjusted. The calender roller set is basically the same as the composite roller set, that is, it is composed of a chrome-plated pressure roller and a silicone pressure roller, but there is no heating device. The main function of the calender roller group is: after the pre-coated plastic film is compounded with the printed product through the composite roller group, the surface brightness is not high, and the surface brightness and bonding strength are greatly improved by the second extrusion of the calender roller group.
3. Transmission system. The transmission system is driven by a computer-controlled high-power motor. After a one-stage gear reduction, a three-stage chain drive drives the movement of the paper feeding mechanism and the rotation of the composite part and the silicone pressure roller of the calendering mechanism. The pressure roller group maintains proper working pressure under the pressure of stepless adjustment.
4. Computer control system. The computer control system adopts a microprocessor, and the hardware configuration consists of a main board, a digital key board, an optical isolation board, a power supply board, and a stepping motor power drive board.
