The mechanical composition and product functions of the coating machine

The coating machine is specifically designed for PET and OPP coating. The coating machine is widely used in the production of transfer aluminum coating, peeling coating film, laser decoration film, electrochemical aluminum film, and other functional coating films. Coating machines can be divided into brush type coating machines; Roller type; Spray coating; Curtain coating; Slit coating.
The speed synchronization and tension configuration of the four major parts of unwinding, coating, traction, and winding are equipped with the AC variable frequency closed-loop vector control system (built-in 32-bit intelligent control card) of CT Company in the UK, which has reached the international advanced level. The entire machine consists of seven parts: unwinding, coating, drying, traction, rewinding, control, and auxiliary devices.
The driving and automatic tension control system for the unwinding and rewinding machines of the coating machine consists of an AC motor, an encoder, a low-friction cylinder pair, an AC variable frequency closed-loop vector control driver, and a tension control program module. It has functions such as speed synchronization, automatic control of tension and taper, and pre action splicing.
The structure of the unwinding and rewinding device is a turret type dual station, with an inflatable shaft for clamping raw materials. The coating machine can achieve automatic flipping of the A and B axes and automatic film connection without stopping the machine, and is equipped with an EPC gas-liquid automatic edge correction system.
All passive guide rollers use hard aluminum alloy pipes, produced in Taiwan. The drying oven of the coating machine is divided into four stages for heating, with automatic temperature control. The inlet and outlet air volume can be adjusted according to the process needs. The guide rollers inside the oven operate synchronously and are equipped with an air top oven and a film piercing operation platform.
All low-voltage electrical components of the coating machine are imported branded components (except for intermediate relays, fuses, and non-standard components). The pneumatic components and main action cylinders are all composed of imported branded accessories.
The control system of the coating machine is programmable and operated through a human-machine interface. Utilizing a fieldbus network system to achieve fully automated control of the production process, reaching the technical level of similar equipment abroad. PT+PLC is responsible for inputting and preprocessing data such as tension and speed of the entire machine, as well as controlling and outputting the control logic of the entire machine., Coating machines are widely used in the production of transfer aluminum films, peel off coating films, laser decoration films, electrochemical aluminum films, and other functional coating films.
