Description
Technical field
A kind of impact mill control system of the swing based on PLC the present invention relates to simple to operate, efficiency high, without potential safety hazard
And its control method, belong to crushing material equipment technical field.
Background technology
Swing impact grinding is a process equipment in small, broken bits being widely used in rock forming mineral sample preparation technology flow, and it processes ore deposit
The operating procedure that sample process is related to generally has：1st, the material alms bowl of mineral sample will be installed by the swing for being placed on swing impact comminution equipment
On disk；2nd, material alms bowl lid is implemented to compress；3rd, cabinet swivelling cover is covered, and buckles cover buckle；When the 4th, setting the processing that mineral crush
Between；5th, motor is started, wobble-plate rotates with motor driven eccentric block, realizes impact ring to the mineral sample impact comminution in material alms bowl；
6th, after set process time reaches setting value, motor is implemented to power off；7th, observing the inertial rotation after motor powers off is
It is no to stop completely；8th, upper box lid is opened, the hold-down mechanism to expecting alms bowl lid is unclamped, is taken from the wobble-plate of swing impact comminution equipment
Discharge alms bowl, crushes and completes.
The mode that prior art is implemented to compress to material alms bowl lid has manual bolts compression and independent jettron to compress.
Implement release and hold-down 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, tend to occur at and implement reversal valve switching manipulation without opening upper box lid, cause because its inertial rotation not yet stops completely
Only just it is released, causes to expect that the accident that alms bowl flies out under effect of inertia occurs.
The generally use time relay or timer switch are controlled on the process time that setting time mineral crush,
Automaticity is not high.
The cabinet swivelling cover of prior art and cabinet snapping, or simple magnet attraction, can be taking human as random opening
Cabinet swivelling cover, security is poor, and after motor power-off, it is often artificial to feel whether material inertial rotation stops completely, so
After open upper box lid, and unclamp the hold-down mechanism to expecting alms bowl lid.This time control mode reliability is low, and material easily occurs and flies
Accident is splashed, intelligent level is also low.
PLC automation control systems are not incorporated into the case of crushing material equipment in the prior art, so research and development also
A kind of swing impact mill control system based on PLC, improve automatization level, security and the operating efficiency of crushing material equipment
Extremely it is necessary.
