Why is the screw of the blow molding machine abnormal?

The reason why the screw of the blow molding machine is abnormal, it still depends on the specific discharge condition of the screw to determine the cause of the abnormal discharge. Today, we will make different reasons for analysis according to different discharge conditions.

There are three reasons for the abnormal discharge of the screw of the blow molding machine sorted out today, and the analysis of the reasons is given below each one.

The screw discharge is unstable. Generally, the screw discharge is too fast or too slow, or the discharge length is different. This usually requires finding the problem from the servo valve and electronic ruler of the blow molding machine, perhaps because the servo valve or the electronic ruler is malfunctioning due to electromagnetic interference.

Affecting the stable blanking process of the screw, there is another reason related to the electronic ruler: the pollution of the electronic ruler will also affect the blanking stability.

Before the screw is discharged, there is no twist. Although this happens before the discharge, it is also one of the abnormal discharges of the screw of the blow molding machine. The processing of raw materials is generally completed by the cooperation of temperature and screw. If there is a problem with the twisting process, the problem will naturally appear in the temperature and screw. If there is no twist, it may be because the temperature is too low and the material is not melted; or the temperature of the discharge port is too high, and the material will be blocked at the discharge port;The reason for the screw is that the screw has quality and performance problems.

The quality of screw discharge is not good. You may have doubts why the quality of screw discharge is also one of the abnormal conditions of screw discharge. Think about it, the material comes out of the screw. If all parts of the screw are normal, will there be a problem with the quality of the output? Therefore, the discharge quality problem is also related to the screw. What is the relationship with the details?

Generally, the temperature is not good or the screw function is not good, and the actual production situation cannot be matched, which will make the raw material melt unevenly, which is also the main reason. Why is the screw of the blow molding machine abnormal? There are different reasons for different conditions. Everyone should have some understanding. According to the conditions they encounter, they can identify where the problem lies and take useful measures.
