Blow molding machine is a relatively common production machine, which is widely used in the production of plastic bottles in related industries. The blow molding machine will inevitably encounter some deviation problems in the automatic production process, which will also cause the weight of the blow molding machine to be different. After all, the machine will inevitably have some small errors, but in addition to these subjective factors, we also need to find some other objective reasons, because these objective reasons seriously affect the accuracy of the blowing weight.
The advantages and characteristics of the blow molding machine in its own design and application:
1. The rational design and automatic control of the blow molding machine greatly reduce power consumption and manpower;
2. Tube blank automatic feeding system;
3. Preheat the tube blank with an infrared preheating heating box;
4. The production process is completed automatically, with less investment, quick results, convenient operation and maintenance, and safety.
Incorrect temperature control or large temperature deviation, unreasonable installation position of temperature measurement point (thermocouple) will lead to periodic temperature deviation. As the temperature deviation increases, so does the deviation affecting weight. When the temperature rises, the stretching of the extrusion barrel increases. In the same operation cycle, the nozzle material at the bottom of the bottle increases and the weight of the product decreases. When the temperature is lower, the weight of the product increases. Similar failures can occur when thermocouples make poor contact. If the thermocouple is damaged, the amount of extrusion will decrease, and when the temperature is below the melting point of the plastic, the motor current will increase.
