Vacuum blister machine operating procedures

1. Boot Preparation

First, check whether the moving parts are in the original position.

2. The oil surface of the vacuum pump must be at the center line of the oil sight mirror, and the vacuum oil should be filled in when it is insufficient.

3. Add oil to the oil mist device, and add appropriate amount of lubricating oil to the moving parts such as the guide column cylinder shaft

4, check the compressor oil level, not enough filling, open the circulating water switch.

5, according to the three-phase power supply, check the vacuum pump or compressor running direction, confirm the correct, can be officially started.

6. Press the main power button, then turn the electric heating switch to preheat, and adjust the heating according to the record of the best state of the same product to avoid wasting materials.

7. Adjust the heating time, cooling time, vacuum time, vacuum delay, upper mold time, demoulding time, delayed blowing, core pulling and secondary upper mold time of each product.

8. Press into the compressed power supply, adjust the pressure to about 0.6 ~ 0.8Mpa, and check whether the movement of the parts is normal.

9. Place the components in the original position, turn the switch to the automatic gear, and run for 3 minutes without load to check whether the programs work normally.

10. After the vacuum pump is started, it will run automatically through the machine. After the lower cylinder rises, the vacuum sound absorption is heard or the vacuum pointer is seen to return, which means the vacuum system is normal.

11. After confirming that all parts are normal, materials can be officially put for normal production.

12. Turn the switch to manual, manually debug whether each action is normal one by one, and turn it to normal.

13. Put the material on the feeding rack, discharge the mold into the lower mold cavity, seal around, turn on the pressing switch, pull the film out of the pressing frame, turn off the pressing switch, press the film with the pressing frame, and adjust the heating time. Push the electric furnace to the working position, heat, observe the heating situation, and make the best product in the best state. After heating, alarm will be started (if heating is not enough, secondary heating can be carried out). Push the electric furnace to the empty position or another mold frame, start the upper and lower molds, turn on the vacuum, turn on the cold air, turn on the water spray, demoulding switch, turn on the pressing sheet switch, and pull out the product.

14, automatic operation, to use the switch, all twist to automatic, such as heating time, the electric furnace back to the empty position, press the automatic start, this opportunity automatically complete the upper mold, lower mold, vacuum, blowing cold air, demoulding.

2. shutdown

1. Turn off the heating power.

2. Turn off the compressor and vacuum pump power supply.

3. Exhaust the vacuum of the vacuum box.

4. Turn off the main switching power supply.

5, the mold with defective cover, so as not to damage the mold
