How does the film slitter correction system work?

The correction system of the film slitter mainly works by detecting the offset of the film in real time and automatically adjusting the position of the film according to the detection results to ensure that the film can maintain the correct position during the scuttling process.

Specifically, the deviation correction system usually includes the following parts:

Correction sensors: Correction sensors (such as photoelectric or ultrasonic sensors) are installed at the appropriate position in the film's transmission path to detect the lateral offset of the film in real time. These sensors are able to accurately measure the distance of the film edge with respect to a preset reference position.

Control system: The control system of the correction system receives the offset signal from the correction sensor and compares it to a preset correction threshold. If the offset exceeds the threshold, the control system will issue an instruction to trigger the correction actuator to act.

Correction actuator: The correction actuator (such as pneumatic or electric correction roller) acts according to the instructions of the control system and adjusts the transmission path of the film to return it to the correct position. These actuators typically have the ability to respond quickly and with precise control to ensure that film offsets can be corrected quickly.

The working process of the entire correction system is a closed-loop control system, which ensures that the film can maintain the exact position during the cutting process through continuous detection, comparison and adjustment, so as to improve the cutting accuracy and product quality. At the same time, the correction system can also adapt to different materials, thicknesses and widths of the film, with a wide range of applicability and flexibility.
