AI Technical Summary

Technical Problem

The current method of replacing battery separator paper rolls relies on manual operation, which leads to low efficiency, high labor costs and the risk of misjudgment. In addition, the operation of robots or robotic arms is complex and costly, making it difficult to meet the needs of high-efficiency production.

Method used

It adopts an air shaft and air jet pipe structure. By opening air pipe perforations on the machine plate and installing air jet pipes, the exhaust roll is blown off by air jets from the back, thus achieving automatic unloading of the roll.

Benefits of technology

It enables automated replacement and splicing of material rolls, reduces equipment complexity and cost, improves the efficiency and stability of unloading operations, and avoids the shortcomings of manual intervention.

Abstract

This utility model discloses an automatic unloading device for a material roll supply system, including an air shaft. The air shaft is horizontally and rotatably mounted on a bearing seat. The air shaft passes through a shaft through hole on a machine plate. A material roll mounting position is provided on the air shaft. The machine plate also has two or more air pipe through holes, each of which has a corresponding air jet pipe inserted into it. The outlet of the air jet pipe faces the material roll mounting position. This utility model's automatic unloading device for a material roll supply system utilizes the air jet pipes to blow air from the back, which not only blows the exhausted material rolls at the material roll mounting position off the air shaft for automatic unloading, but also, compared to unloading by robots or robotic arms, has a simpler structure, simpler design, and is easier to manufacture and install. Furthermore, it eliminates the need for precise positioning and motion calculations required by robots and robotic arms, resulting in high unloading efficiency.
