1100mm Four-Unwind Automatic Cross Cutting and Packaging Machine
Description
The DBHQ-1100ZB-4F 1100 4-Unwind Automatic Cross Cutting Packaging Machine is a high-efficiency solution designed for processing large roll materials such as paper, self-adhesive labels, paper-plastic laminates, and non-woven fabrics. Equipped with a servo motor control system, the machine ensures precise fixed-length cutting with high accuracy and stability. The integrated system combines pneumatic, optical, and electrical controls, delivering smooth operation, low noise, and reliable performance. Featuring four unwinding stations, automatic tension control with magnetic powder taper adjustment, and inverter speed regulation, it enables continuous production with improved efficiency. The Panasonic PLC and touch screen interface provide intelligent control functions including automatic counting, preset length cutting, and alarm stop. Built with a heavy-duty steel frame and high-precision components, this machine offers fast cutting speed, consistent quality, and is an ideal choice for modern large-scale roll material converting applications.
