Advantages and characteristics of the automatic bottle blowing machine in its own design and application:
1. Reasonable design, fully automatic control, greatly reducing power consumption and manpower;
2. Automatic tube blank loading system;
3. The infrared preheating heating box is used to preheat the tube blank;
4. The production process is completely automated, with the advantages of less investment, quick results, convenient and safe operation and maintenance.
The temperature control is inaccurate or the temperature deviation is large, and the installation position of the temperature measuring points (thermocouples) is unreasonable, resulting in periodic temperature deviation. As the temperature deviation increases, the deviation affecting the weight also increases. When the temperature rises, the extrusion barrel stretch increases. In the same operation cycle, the nozzle material at the bottom of the bottle increases, and the product weight decreases. When the temperature is low, the weight of the product increases. When the thermocouple has poor contact, there is a similar fault. If the thermocouple is broken, the extrusion amount decreases, and then the motor current increases when it is lower than the temperature of the plastic melting point.
