The five roll transfer coater is a kind of roll coater. The five rolls have the same diameter, and are composed of uniform rubber roll, metering roll, transfer steel roll, coating roll and coating pressure steel roll, glue supply component, driving device and frame component.

The motion of coating roll of five roll transfer coater can be divided into synchronous or asynchronous control. When the asynchronous control mode is adopted, the coating roller operates independently; when the synchronous control mode is adopted, the operation speed of the coating roller is controlled by the coil tension; because the five rollers are separately driven by five servo motors and a reducer, and the coupling is separately driven. The speed ratio among metering roll, transfer roll and coating roll can be set on the touch screen, which is controlled by PLC and touch screen: there is a set of scraper on the transfer roll, and the glue at both ends of the paper with a width of less than 1000mm will be scraped off by the scraper.

The working principle of five roll transfer coater is shown in the figure

A: Rubber roller

B: Metering roll

C: Transfer steel roll

D: Coating roller

E: Coated steel roller
