AI Technical Summary

Technical Problem

Traditional self-adhesive composite paper slitting devices suffer from slow slitting speed, insufficient precision, and inadequate control over paper tension and flatness, resulting in low production efficiency and material waste, making it difficult to meet the needs of large-scale production.

Method used

The system employs a stepper motor, gears, and racks to achieve precise adjustment of the cutting position and height. Combined with the cooperation of the telescopic rod and the fixed plate, it ensures cutting accuracy. The auxiliary pressure roller and the rubber ring work together to ensure flat paper feeding. The motor-driven take-up roller achieves automated feeding and reduces manual intervention.

Benefits of technology

It improves slitting accuracy and production efficiency, reduces material waste, enhances product qualification rate and enterprise competitiveness, and ensures slitting quality and stability.
