AI Technical Summary

Technical Problem

During the steel plate shearing process, the motor of the roller conveyor below the pressure roller is easily damaged due to excessive torque, which causes the roller conveyor to malfunction, affecting the integrity of the equipment and the utilization rate of the roller conveyor.

Method used

A status detection device is used to detect the position and pressure status of the pressure roller, and the power supply status of the roller conveyor motor is controlled by a control device and a relay system to ensure that the roller conveyor operates normally when the pressure roller is raised and loses power when the pressure roller is pressed down, so as to avoid damage caused by excessive torque.

Benefits of technology

It effectively protects the lower roller conveyor motor, preventing damage caused by excessive torque, and ensuring the stable operation of the roller conveyor system and the integrity of the equipment.

Abstract

The utility model discloses a system of protecting the rollaway motor below the compression roller, including compression roller device, controlling means, intermediate relay, contactor, rollaway motor, wherein, including state detection device in compression roller device, and the output of state detection device is connected with the input of controlling means, and the output of controlling means is connected with the first coil of intermediate relay, and the first coil of intermediate relay is connected with the first input of contactor through the contact of intermediate relay, and the second input of contactor is connected with external power supply, and the output of contactor is connected with rollaway motor. When the compression roller is pressed, state detection device detects the compression of compression roller device, and sends state information to controlling means, and controlling means controls relay coil not to be electrified, and contact is disconnected, and contactor also does not get electricity, and the lower rollaway motor loses electricity, and the damage of the lower rollaway motor caused by the larger torque of pressure can be avoided.
