Automatic blow molding machine is a very common production machine, widely used in the production of plastic bottles in related industries. The automatic blow molding machine will inevitably encounter some deviation problems when it is fully automatic production, and it is also appropriate to cause the weight of the blowing bottle to be different. After all, automatic blow molding machine will inevitably have some minor errors. But we have to look for other objective reasons besides these subjective factors, because these objective reasons seriously affect the accuracy of blowing bottle weight.
The advantages and characteristics of the automatic blow molding machine in its own design and application:
1. Reasonable design, full automatic control, greatly reduce the power consumption and manpower;
2. Automatic billet system;
3. The infrared preheating box is used to Preheat the tube billet;
4. The production process is fully automated and has the advantages of less investment, faster results, and convenient and safe operation and maintenance. The temperature control is not accurate or the temperature deviation is large, and the installation position of the temperature measurement point(thermocouple) is unreasonable, which causes the temperature to produce periodic deviation. With the increase of the temperature deviation, the deviation affecting the weight also increases. When the temperature rises, the extrusion tube is stretched and increased. In the same operating cycle, the water mouth material on the bottom of the bottle is increased and the product weight is reduced. When the temperature is low, the weight of the product increases. When the thermocouple has poor contact, there is a similar failure. If the thermocouple is bad, the extrusion amount decreases, and when it is lower than the temperature of the plastic melting point, the motor current increases.
