AI Technical Summary

Technical Problem

Existing corona roller and corona pressure roller gap adjustment mechanisms are inconvenient to adjust, have poor reliability and high cost. Common adjustment methods such as adjusting screws cannot guarantee gap uniformity, cylinders are easily affected by air pressure fluctuations, and hydraulic cylinders are expensive and complex systems.

Method used

The system employs a fine-tuning mechanism, including components such as a vertical plate, camshaft, motor, moving block, and corona roller. Through the cooperation of the camshaft and motor, it achieves precise adjustment of the gap between the corona roller and the corona roller, reducing wear, improving reliability, and lowering costs.

Benefits of technology

It achieves uniform adjustment of the gap between the corona roller and the corona roller, improves the reliability of adjustment and reduces costs, avoids wear caused by direct friction, and has a simple and rigid structure.

Abstract

This utility model relates to a fine-tuning mechanism for the gap of a corona pressure roller, comprising: a fine-tuning mechanism and two upright plates; each of the two upright plates has a guide groove on one side; the fine-tuning mechanism includes a movable block disposed inside the guide groove and a camshaft disposed between the two upright plates, with a corona pressure roller disposed between the two movable blocks, the corona pressure roller being located above the camshaft, and a motor with an output shaft connected to the camshaft disposed on one side of each upright plate. This utility model, by configuring components such as upright plates, a camshaft, a corona pressure roller, a motor, and movable blocks, and through the cooperation between the movable blocks and the upright plates, allows the corona pressure roller to move vertically along the direction of the guide groove under the action of the movable blocks. When the motor drives the camshaft to rotate, the camshaft pushes the corona pressure roller upward; conversely, the movable blocks can move downward under the action of gravity, thereby adjusting the size of the gap between the corona pressure roller and the corona roller.
