AI Technical Summary

Technical Problem

Existing cordless paper feeding devices are prone to paper edge curling during airflow lifting, which affects the traction effect.

Method used

By setting up a separator and folding plate inside the air guide frame, and using a distance sensor to regulate the airflow, the uniformity of airflow at the edge and center of the paper is ensured. A scraper is set on one side of the conveyor belt to keep the paper in close contact, and multiple air pumps are used to adjust the airflow speed and direction.

Benefits of technology

It effectively reduces paper edge curling, improves paper traction stability and smoothness, and reduces curling caused by uneven airflow between the paper edge and center.
