AI Technical Summary

Technical Problem

In papermaking pressing equipment, poor synchronization between the auxiliary roller and the main roller leads to uneven dewatering of the paper surface, affecting product quality and accelerating the wear and tear of the rollers and felt.

Method used

By setting a proximity switch in the pressing equipment to detect the position of the moving roller, the working state of the hydraulic device is controlled, so that the two ends of the moving roller move towards the main roller synchronously, thus ensuring synchronization.

Benefits of technology

It effectively solved the problem of inconsistent linear pressure on the roller surface, and improved the service life of the equipment and the pressing quality of the paper.

Abstract

The application provides a papermaking pressing device and a control method thereof. The papermaking pressing device comprises a main roller, a moving roller, a hydraulic device and a proximity switch. The moving roller is connected with the hydraulic device and can approach or move away from the main roller under the drive of the hydraulic device, thereby pressing paper products between the main roller and the moving roller. The proximity switch is used for detecting the synchronous position state of the moving roller, thereby assisting in controlling the working state of the hydraulic device. The papermaking pressing device provided by the application can effectively solve the problem of asynchronous closing of the operation side and the transmission side, and can improve the problem of inconsistent linear pressure on the roller surface and prolong the service life of the equipment by detecting that the two sides of the moving roller are in the synchronous position at the same time and assisting in controlling the working state of the hydraulic device (synchronously driving the two ends of the moving roller to approach the main roller) with minimum investment.
