1. Process Requirements: The coating machine needs to evenly apply adhesive or ink-like materials onto the surfaces of aluminum foil, plastic films, or fabric textiles. This places high demands on the coating process, requiring not only uniform coating thickness but also the ability to perform high-speed, non-stop roll changes to enhance production efficiency. 2. Advantages of the Solution: 1. Tension control at each stage is managed by a frequency inverter, with tension sensors ensuring precise and stable tension regulation—resulting in a simple yet reliable system. A PLC or synchronous controller is used to synchronize the speed of the drive roller’s frequency inverter, while simultaneously providing the linear velocity signal to other inverters in the system. 2. The dual-station winding and unwinding mechanism features pre-drive functionality, enabling it to meet the demands of high-speed operations.

1. Process Requirements
 
  The coating machine needs to evenly adhere adhesive or ink-like materials onto the surfaces of aluminum foil, plastic films, or fabric textiles. This process demands high precision—requiring not only uniformly thick coatings but also enabling fast, non-stop roll changes to boost production efficiency.
 
II. Advantages of the Plan:
 
1. Tension control at each level is achieved using a frequency inverter, with tension sensors providing precise feedback for stable and straightforward system operation. A PLC or synchronous controller manages the speed of the drive roller’s frequency inverter, while simultaneously serving as the linear velocity signal for the other inverters in the system.
 
2. The dual-station unwinding and rewinding system features pre-drive functionality, enabling high-speed, non-stop automatic roll changes and boosting production efficiency. At the same time, precise rewind control prevents undesirable core-shift winding patterns, resulting in superior rewind quality.
