The Film Slitter Rewinder structure consists of an integrated steel plate welded frame, equipped with upper and lower double unwinding shafts and sliding double rewinding shafts. The central operating console integrates a Siemens touch screen and an electric control cabinet. The front section is a material guide rack and a deviation correction system. The middle section is equipped with a pneumatic circular knife or flat knife cutting unit. The tail section is equipped with a differential pressure roller and an automatic unloading system. It is a high-speed slitting and rewinding equipment designed for environmentally friendly degradable films and sanitary materials.

1. Professional adaptation - Optimization of degradable film process

Film Slitter Rewinder is specially developed for the characteristics of PLA, PBAT, starch-based and other degradable materials that are easy to deform and stretch. Through adaptive tension control and low-tension sliding rewinding system, the film is guaranteed not to break or wrinkle at high speed, and the slitting width range is controlled between 50mm-1200mm.

2. Precise control - centralized drive by Siemens SIMATIC system

Film Slitter Rewinder adopts Siemens SIMATIC motion control platform to control the main shaft, corona device, pressure roller and waste discharge system in linkage to achieve multi-axis collaborative processing. The response cycle is less than 1ms, and with the high-speed operation capability of 600m/min, it effectively improves the operation stability and operation sensitivity of the equipment.

3. High-definition correction - CCD visual guidance system

Film Slitter Rewinder is equipped with an imported CCD correction system, which supports full-width scanning and automatically adjusts the tape path, with a correction accuracy of ±0.05mm. The system supports printed marking line recognition and transparent film detection to ensure that the slitting position is always consistent, especially suitable for printed films and environmentally friendly packaging materials with positioning requirements.

4. Uniform pressure control - automatic differential pressure rewinding pressure roller

Film Slitter Rewinder is equipped with an intelligent differential pressure feedback device, which automatically adjusts the pressure of the pressure roller according to the rewinding diameter to ensure that different materials always maintain a constant contact pressure. The maximum rewinding diameter is Φ1000mm, and the pressure range is controlled at 0.1~0.4Mpa, which effectively improves the tightness of the finished product curling and the consistency of exhaust.

5. High-efficiency auxiliary - corona treatment device

Film Slitter Rewinder integrates a corona treatment module, which is suitable for enhancing the surface tension of the film and improving the surface activity before lamination and printing. The maximum corona power can reach 3KW, which can process various film materials with a width of 1300~2500mm, providing stable output conditions for subsequent processes.

1. Eco-friendly Food-grade Film Processing

The machine is also applied in the slitting of degradable films for food-related packaging. Zhaoan Tech integrates this equipment to deliver precise and stable slitting of biodegradable films, helping clients replace conventional plastics with environmentally friendly alternatives while maintaining packaging strength and safety.
