Automatic blow molding machine is a very common production machine, which is widely used in the production of plastic bottles in related industries. The automatic blow molding machine will inevitably encounter some error problems during fully automatic production. It is also necessary to cause the blow molding weight to be different. After all, the machine will inevitably have some small errors, but we are looking for other subjective factors. Find some other objective reasons, because these objective reasons seriously affect the accuracy of the blowing weight.
The 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 billet loading system;
3. Use infrared preheating heating box to preheat the tube;
4. The production process is fully automated, which has the advantages of less investment, quick results, convenient and safe operation and maintenance.
The temperature control is inaccurate or the temperature error is large, and the installation position of the temperature measuring point (thermocouple) is unreasonable, which causes periodic errors in the temperature. As the temperature error margin increases, the error affecting the weight also increases. When the temperature rises, the extrusion barrel stretches more. In the same operating cycle, the nozzle material at the bottom of the bottle increases and the product weight is reduced. When the temperature is low, the weight of the product increases. When the thermocouple has poor contact, there will be similar failures. If the thermocouple is broken, the extrusion volume will decrease. When the temperature is lower than the melting point of the plastic, the motor current will increase.
Bottle blowing machine is a machine used to blow bottles. It uses some plastic raw materials to make plastic bottles or process some used plastic bottles from scratch to produce new clean plastic bottles. With the continuous development of my country's beverage industry and pharmaceutical industry, even in recent years, there has been a trend of bursting, and the bottle blowing machine has also developed by leaps and bounds.
