When the utility model PVC extruder 25 does not work, the first electric pushrod 6,13 extension bar of third electric pushrod stretches out
(in running order), 12 extension bar of the second electric pushrod retract and (are in reset state)；Life is debugged when PVC extruder 25 is switched on
Production. art checks material plasticizing state, or shuts down and need to start feeding motor to when the charging of the feed opening 11 of PVC extruder 25
16, while electric signal is issued to the second electric pushrod 12 and third electric pushrod 13, stretch out 13 extension bar of third electric pushrod
It is in running order, feed back pipe 7 is closed, 13 extension bar of third electric pushrod, which retracts, is in reset state, and opening leads to feed opening
11 the second feed pipe 9, material passes through the promotion of helical blade 15, by middle hopper 4, along charge pipe 5, the second feed pipe
9 flow into feed opening 11；When the material in feed opening 11 reaches the high charge level of setting, level-sensing device is to feeding motor in feed opening 11
16, the second electric pushrod 12 and third electric pushrod 13 issue electric signal, shut down feeding motor 16, and third electric pushrod 13 stretches out
Bar stretching is in running order, closes the second feed pipe 9 led at feed opening 11, realizes the real-time of the charging process of feed opening 11
Stop, while 12 extension bar of the second electric pushrod is retracted and resetted, and feed back pipe 7 is connected；After shutting down feeding motor 16, by inertia institute
The material of promotion flows back into charging hopper 6 along feed back pipe 7；When the level-sensing device of feed opening 11 detects low material position, upwards
Expect that motor 16, third electric pushrod 13 and the second electric pushrod 12 issue electric signal, starts feeding motor 16, third electric pushrod
13 reset, and lead to the second feed pipe 9 of feed opening 11, while 12 extension bar of the second electric pushrod stretches out and is in work shape
State closes feed back pipe 7, is simultaneously emitted by electric signal and starts low material position warning device sending alarm, alarm lamp is bright.
When the trial production of PVC formulation material needs to feed to the main hopper 10 of PVC extruder 25, third electric pushrod 13 and second
12 extension bar of electric pushrod stretches out (in running order), and 6 extension bar of the first electric pushrod of electric pushrod retracts (in reset shape
State), and then the second feed pipe 9 and feed back pipe 7 for leading to feed opening 11 are closed, lead to the first feed pipe 8 of main hopper 10；
When the material in main hopper 10 reaches the high charge level of setting, the level-sensing device being equipped in main hopper 10 is electric to feeding motor 16, first
Dynamic push rod 6 and the second electric pushrod 12 issue electric signal, shut down feeding motor 16, and the second electric pushrod 12 resets, and feed back is connected
Pipe 7,6 extension bar of the first electric pushrod stretch out in running order, the first feed pipe 8 of closing main hopper 10；When main hopper 10
In material when reaching the low material position of setting, level-sensing device in main hopper 10 is to feeding motor 16, the second electric pushrod 12 and first
Electric pushrod 6 and low material position warning device issue electric signal, open feeding motor 16, and 12 extension bar of the second electric pushrod is stretched
Out, end feed back pipe 7, the first electric pushrod 6, which retracts, to be resetted, and the charge pipe 5 of main hopper 10 is connected, while position warning device issues
Alarm, alarm lamp are bright.
By level-sensing device, the first electric pushrod 6, the second electric pushrod 12 and third electric pushrod 13, may be implemented to PVC
The real-time monitoring of material position and charging, the real-time control for stopping material in the main hopper 10 and feed opening 11 of extruder 25；And feed back pipe 7
It designs after feeding motor 16 is shut down because the material that inertia is promoted flows back into loading hopper 2 in time, avoids in middle hopper 4
Excessive blocking 17 rotary resistance of transmission shaft for causing feeding motor 16 connected of aggregation extruding is excessive, damages feeding motor 16.
In addition, in the normal productive process of PVC product, when rate of feeding is too fast, or because of temperature of charge fluctuation, formula
When changing so that 25 blanking section material plasticizing of PVC extruder is inadequate, it may appear that when material flows into feed opening 11 by main hopper 10, overflow
Out the phenomenon that feed opening 11, feed system is assisted using the PVC powder of the utility model, when material reaches the low material of feed opening 11
When position, the level-sensing device in feed opening 11 issues electric signal to low material position warning device, and warning device makes a sound, alarm lamp
Bright, warning operating personnel has found and handles in time, avoids material and flows into waste of material caused by spilling in feed opening 11, simultaneously
It also avoids material to overflow in the region pollution caused by operating environment for being not easy booting cleaning, saves operating personnel to spilling
The cleaning of material.
Above to level-sensing device, feeding motor 16 and the first electric pushrod 6, the second electric pushrod 12 and third electric pushrod 13
The control mutually opened and closed selects PLC to be controlled, and control method is existing control principle, and the application is not repeating.
