How to do the right test of the hollow blow molding machine?

Before the hollow blow molding machine is officially started up, it must be tested and inspected to ensure that the equipment can complete the next production work normally. The test run inspection can be divided into two steps: the barrel without heating test run and the barrel heating test run.


1. The barrel does not heat up and test run inspection


The cylinder of the hollow blow molding machine is not heated up and the test run inspection has the following 10 steps.

1. The control box circuit is closed for power supply.

2. Start the lubricating oil pump, lubricate the gear box for 3 minutes, and add lubricating oil to each lubrication part.

3. Check the hopper, there should be no foreign matter inside, and then move the V-belt again, it should rotate smoothly without blocking.

4. Start the screw drive motor at low speed.

5. Observe whether the pointers of the voltmeter and ammeter swing normally.

6. Whether the direction of the nuclear cold screw is correct.

7. The emergency stop button on the inspection and test equipment should work accurately and reliably.

8. Check whether the lubricating oil working pipeline is unobstructed, whether the fuel injection position is correct, and whether there is any oil leakage in various parts.

9. Check the water supply of the cooling water pipeline, and there should be no leakage.

10. Withdraw the screw and check the high and low speed of the screw drive shaft, which should be consistent with the instructions.


II, the barrel heating test run inspection


1. Each section of the barrel is heated and increased, and the temperature control instrument is adjusted according to the process temperature requirements.

2. Detect the temperature of each section of the barrel with a mercury thermometer, verify and adjust the display temperature of the meter and the detected temperature of the mercury thermometer.

3. Check whether there is a heating circuit break alarm in the heating device and whether it can work correctly.

4. After the barrel is heated to the process temperature, it is heated at a constant temperature and the heating time is recorded.

5. Re-tighten the connecting screw between the barrel and the barrel base.

6. Start the drive screw motor at a low speed, observe whether the voltage and current meter swing is abnormal; check whether the screw rotation is stable, and listen to whether the operating sound of each part of the transmission is abnormal. Everything is normal and stop immediately. Note: The screw dry running time should not exceed 3min.
