Comprehensive understanding of automatic blow molding machines and specific applications


In addition to the convenient and convenient operation […]

In addition to the convenient and convenient operation methods in the actual use and operation of the automatic bottle blowing machine, the more important thing is its safety and stability, fully automatic operation, without human intervention, scientific and tight coordination of all parts, blow molding The action is more standardized and standard than manual operation, and achieves a high degree of uniformity. The standardized automatic production process avoids the occurrence of unexpected situations. In this way, the product production environment is very safe and reliable.

Fully automated operation without human intervention, so that after the product manufacturing process, the product and the external environment are avoided, so that the product produced is very clean, without the entry of external pollutants and bacteria, and the packaging is healthy. Product safety, so that the fully automatic bottle blowing machine can be connected with the filling production system for supporting production, which also improves labor efficiency. Because of such excellent technology, fully automatic blow molding machines are widely used in the field of food packaging, cosmetic bottle making and candy food packaging.

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 blank feeding system;

3. Use infrared preheating box to preheat the tube;

4. The production process is fully automated, with the advantages of low investment, quick results, 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. As the temperature deviation increases, the deviation that affects 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.

1. The screw central shaft and cylinder are made of 38CrMoAlA chromium, molybdenum, aluminum alloy through nitrogen treatment, which has the advantages of high thickness, corrosion resistance and wear resistance.

2. The die head is chrome-plated, and the screw spindle structure makes the discharge more even and smooth, and better completes the blown film. The complex structure of the film blowing machine makes the output gas more uniform. The lifting unit adopts a square frame platform structure, and the height of the lifting frame can be automatically adjusted according to different technical requirements.

3. The unloading equipment adopts peeling rotating equipment and central rotating equipment, and adopts a torque motor to adjust the smoothness of the film, which is easy to operate.
