It uses a special multifunctional coating head and can achieve various forms of surface coating. The rewinding and unwinding of the coating machine are equipped with full-speed automatic film splicing mechanisms and PLC program tension closed-loop automatic control.

[0003] Chinese patent CN219098221U discloses a bubble-free winding device for a coating machine, which includes a winding station, a pressure measuring trolley and a trolley driving source.

The technical solution can detect the change in the winding diameter or the winding diameter size of the first winding roller or the second winding roller in real time. When the winding diameter of the material roll reaches a preset parameter, the pressure measuring sensor triggers the rotating driving source and the trolley driving source, and the trolley driving source drives the pressure measuring trolley away from the winding station, and then the rotating driving source is used to drive the first winding roller and the second winding roller to swap positions, and then the trolley driving source drives the pressure measuring trolley to approach the winding station again. Such a structural design can fully automatically change rolls and unload materials, greatly optimizes the winding efficiency, and ensures that the pressure of the pressure wheel assembly and the winding roller is constant, which solves the technical problem of bubbles appearing during winding in the traditional solution.
