Description
Technical field
The present invention relates to a kind of swings based on PLC easy to operate, high-efficient, without security risk to impact mill control system
And its control method, belong to crushing material equipment technical field.
Background technique
Swing impact grinding is a process equipment fine crushing being widely used in rock forming mineral sample preparation process flow, processes mine
The operating procedure that sample process is related to usually has: 1, will install the material alms bowl of mineral sample by the swing for being placed on swing impact comminution equipment
On disk；2, material alms bowl lid is implemented to compress；3, cabinet rotation is covered, and buckles cover buckle；4, when the processing that setting mineral crush
Between；5, start motor, swinging disc drives eccentric block to rotate with motor, realizes impact ring to the mineral sample impact comminution in material alms bowl；
6, after set process time reaches setting value, motor is implemented to power off；7, the inertial rotation after the power-off of observation motor is
No complete stopping；8, upper box lid is opened, the hold-down mechanism to material alms bowl lid is unclamped, is taken from the swinging disc of swing impact comminution equipment
Discharge alms bowl, crushes and completes.
The prior art has manual bolts compression and independent jettron to compress the mode that material alms bowl lid is implemented to compress.
Implement to loosen and press bolt mechanism manually in screw thread hold-down mechanism, it is laborious, bothersome；In independent pneumatic clamping mechanism
In, cylinder or air bag are depressurized by implementing commutation to commutation threshold switch, realizes and unclamps air clamper.In this one mistake of operation
Cheng Zhong is tended to occur at and is implemented commutation threshold switch operation without opening upper box lid, causes not yet to stop completely due to its inertial rotation
It is only just released, causes to expect that the accident that alms bowl flies out under effect of inertia occurs.
The time relay is generallyd use on the process time that setting time mineral crush or timer switch is controlled,
The degree of automation is not high.
Cabinet rotation lid and the cabinet snapping of the prior art, or simple magnet are attracted, can be taking human as arbitrarily opening
Cabinet rotation lid, safety is poor, and after motor power-off, often artificially feels whether material inertial rotation stops completely, so
After open upper box lid, and unclamp the hold-down mechanism to material alms bowl lid.This time control mode reliability is low, is easy to happen material and flies
Accident is splashed, intelligent level is also low.
There are no the cases that PLC automatic control system is introduced into crushing material equipment in the prior art, so research and development
A kind of swing impact mill control system based on PLC, improves automatization level, safety and the working efficiency of crushing material equipment
Be very it is necessary to.
