The unstable pressure of the beverage straw extruder is usually judged by the pressure sensor. For example, the number on the pressure sensor changes back and forth from 50 kg to 100 kg;
If the PLA straw extruder does not have a pressure gauge, subjective judgment based on the amount of material discharged from the straw extruder cannot be summarized as unstable pressure.
Generally, this kind of instability in subjective judgment is most likely due to the following reasons:
1. The triangle belt is very loose and the belt is slipping;
2. The contact of the speed regulator is unstable, causing the parameters transmitted by the inverter to the motor to fluctuate high and low;
3. If the PLA material entering the screw gets damp, it will cause the PLA material coming out of the hopper to be discharged and not discharged for a while, and the screw will be extruded out sometimes more and sometimes less;
The above are the relevant answers about what causes unstable pressure in the extruder. I hope it will be helpful to you.
