Quality, speed and operation adjustment of plastic bottle blowing machine
1 Bottle mouth aggregate, increase the temperature of the first layer of lamp, or close the cooling water outlet valve at the bottle mouth.
2. The bottle body is blue, stretched and white, indicating that the temperature of the light box is low. Adjust the temperature of the corresponding section of the lamp according to the white position.
3. The milky white and whitish bottle body indicates that the temperature of the light box is too high. Adjust the temperature of the corresponding section of the lamp according to the whitish position.
4. Deformation of the bottle mouth indicates that the temperature of the bottle mouth is too high, reduce the first layer temperature.
5. The bottleneck becomes thicker and the pre-blowing delay time is too short. Increase the pre-blowing delay in units of 0.01S.
6. A belly button appears at the bottom of the bottle, and the pre-blowing delay is too high. Adjust it to a lower level, with 0.01S units.
Adjusting the production speed of the bottle blowing machine
By increasing the exhaust time and increasing the saturation time to slow down the speed, while reducing the overall temperature of the light box, the overall temperature of the light box needs to be reduced by 1% for each increase of 0.1S. Increasing speed is the opposite of reducing speed. (The exhaust time is as low as 0.8S, and the bottle skipping phenomenon will occur after the exhaust is not in time after 0.8S) Regardless of the speed increase or decrease, it should not be too fast. Change the bottle by 0.3S each time after a period of time. After the bottle quality is stable, adjust the speed. Every time you adjust the speed, you must carefully observe the quality of the bottle and adjust the temperature of the light box at any time. Every time the bottle blowing cycle changes by 0.1S, the output of the bottle changes by about 50 per hour. The plastic bottle blowing machine should adjust the blowing speed according to the speed of the filling machine.
Blow Molding Machine Operation Manual: Operation
1. Check the water level of the cold water tank and turn on the mold cooling water pump.
2. Check the water level of the cold water tower and turn on the bottle-mouth cooling water pump. 3. Turn on the high-pressure air compressor and turn on the cold dryer.
4. Check the high pressure gauge of the machine, and the machine can be turned on only when the pressure reaches 29 kg. After manual origin, turn on automatic to see if the machine is operating normally. After everything is normal, press the "heating start" and "blowing" buttons.
5. After the light box reaches the set heating temperature, press the "embedding button".
