A plc rotary pendulum impact mill control system and its control method

Abstract

The invention discloses a PLC-based (Programmable Logic Controller) rotary oscillating impact mill control system. The PLC-based rotary oscillating impact mill control system comprises a motor, a case, a material pot tank and a material pot cover, and further comprises an electric mortise lock coil, an electromagnetic directional valve coil, a pressure switch, an alternating current contactor, anair bag, an electromagnetic directional valve, an infrared detector, a PLC, a touch screen and an electric mortise lock mechanism, the touch screen operates the PLC-based control system to control thewhole material pulverizing process, the material pot cover is compressed through an air bag compression mechanism, the time spent in opening a rotary cover of an upper case is controlled through theinfrared detector, the degree of automation is high, the working efficiency is high, and the safety coefficient is high.

Description

technical field [0001] The invention relates to a PLC-based rotary pendulum impact mill control system and a control method thereof with simple operation, high efficiency and no potential safety hazard, and belongs to the technical field of material crushing equipment. Background technique [0002] The pendulum impact mill is a fine crushing equipment widely used in the preparation process of rock mineral samples. The operation steps involved in the process of processing ore samples usually include: 1. Put the material bowl filled with mineral samples on the pendulum impact mill. 2. Press the cover of the material bowl; 3. Cover the rotating cover of the chassis and buckle the cover; 4. Set the processing time of mineral crushing; 5. Start the motor, and the swing plate will follow The motor drives the eccentric block to rotate, and the impact ring crushes the mineral samples in the material bowl; 6. After the set processing time reaches the set value, the motor is powered o...

AI Technical Summary

Problems solved by technology

In the process of this operation, it often occurs that the reversing valve switch operation is carried out without opening the upper box cover, resulting in the accident that the inertial rotation is not completely stopped before it is released, causing the material bowl to fly out under the action of inertia.

[0004] The processing time of mineral crushing is usually controlled by time relay or timer switch, and the degree of automation is not high.

[0005] In the prior art, the revolving cover of the case is fastened to the case, or is simply attracted by a magnet, and the revolving cover of the case can be opened artificially at will, which is poor in safety. After the motor is powered off, it is often artificially felt whether the inertial rotation of the material has completely stopped. Then uncover the upper box cover, and loosen the pressing mechanism for the material bowl cover

This time control method has low reliability, is prone to material splash accidents, and has a low level of intelligence

[0006] In the prior art, there is no case of introducing the PLC automatic control system to the material crushing equipment, so it is necessary to develop a PLC-based rotary pendulum impact mill control system to improve the automation level, safety and work efficiency of the material crushing equipment of
