Advantages and features of the automatic blow moulding machine in its own design and application:
1. Reasonable design and fully automatic control, greatly reducing power consumption and manpower;
2. Automatic tube blank system;
3. Infrared preheating heating box to preheat the tube blank;
4. The automatic blow molding machine production process is fully automated, with the advantages of less investment, quick effect, convenient operation and maintenance.
The temperature control is inaccurate or the temperature deviation is large. The installation position of the temperature measurement point (thermocouple) is unreasonable, causing the temperature to have a periodic deviation. As the temperature deviation increases, the weight deviation also increases. When the temperature rises, the extrusion barrel is stretched more, and in the same operation cycle, the nozzle material of the bottom of the bottle is increased, and the weight of the product is reduced. When the temperature is low, the weight of the product is increased. When the thermocouple has poor contact, there is a similar failure. If the thermocouple is broken, the extrusion amount is reduced, and when the temperature is lower than the melting point of the plastic, the motor current increases.
