What are the uncertainties in the production of a bottle blowing machine
Feb 27, 2018

What are the uncertainties in the production of a bottle blowing machine?

During the production of automatic bottle blowing machine, the weight of the product is often unstable, and the weight of the product exceeds the prescribed deviation. Feature weight instability is the bottle nozzle material appears at the bottom of different lengths, serious due to the length of the tube is not enough to make the product material blow molding, causes weight instability mainly in the following situations:

1, the temperature control is not accurate or the temperature deviation is large in the production of bottle blowing machine. The installation position of the thermocouple (thermocouple) is unreasonable, causing the temperature to have periodic deviation. With the increase of temperature deviation, the deviation of the influence weight also increases. When the temperature rises, the extruding barrel is stretched. In the same operation period, the nozzle material at the bottom of the bottle increases and the weight of the product is reduced. When the temperature is low, the weight of the product is aggravated. When there is a bad contact between the thermocouple, there is a similar failure. If the thermocouple is bad, then the extrusion volume will decrease, and then the temperature of the melting point will increase. It is impossible to squeeze out the melting point of the plastic. Whether the installation position of the thermocouple is reasonable and the temperature control area of the thermocouple point will directly affect the stability of the extrusion.

2,The running time of the 2 and two die frames is not consistent. The difference between the two sides of the die carrier is very unstable when the flow rate is constant. The weight of the mould frame running faster is heavier, and the slow running of the mold frame is lighter because of the tension. The solution is to adjust the die frame on both sides to make the running time close.

3, the extrusion quantity is unstable, due to the unstable speed of the motor running and the unfit of the light tightness of the belt, the extrusion quantity is unstable.

4, the cause of plastic raw materials is different due to the change of the proportion of different plastic raw materials or proportions. The number of additives added to the water and the material often affects the extrusion volume.

Zhangjiagang Eceng Machinery Co., Ltd. specializes in the development and production of various specifications of the bottle blowing machine manufacturers.
