AI Technical Summary

Technical Problem

In emergency situations, when an open mill is stopped, the rollers reverse, causing damage to equipment parts and secondary injuries to personnel. Furthermore, the inertial impact load is large, and the existing foot-operated emergency stop device cannot effectively protect the equipment and operators.

Method used

Design a foot-kick emergency stop mixing roller reversal device for open mills, including a moving module, a deceleration module, and a reverse rotation module. The device automatically discharges foreign objects by separating the roller body, decelerating, and reversing rotation, thus avoiding continuous compression and secondary damage.

Benefits of technology

It enables safe and efficient separation and reversal of the rollers without human intervention in emergency situations, protecting equipment components and operators and avoiding secondary injuries and impact loads.

Abstract

The application discloses a two-roller reverse rotation device for open mill after emergency stop, which comprises a moving module, a deceleration module and a reverse rotation module. The moving module comprises a frame arranged on the machine body and a flange arranged inside the frame. The flange can be controlled to carry a second gear and a second roller body away from a first roller body. The reverse rotation module is used for driving the first roller body and the second roller body to rotate in a second direction. The application relates to the technical field of open mill equipment, and combines roller body separation, inertia deceleration and automatic reverse rotation. After the machine body is suddenly stopped, the moving module first separates the two roller bodies to avoid continuous extrusion; the deceleration module then automatically brakes the driven roller to prevent foreign matters from continuing to be wound in. The whole process does not need manual intervention, and the risk of secondary injury is avoided. By separating the two roller bodies first and then reversing, impact load is relieved in the separation process, and equipment parts are effectively protected.
