2. Structure

8. Mountthemelt pump on the frame, and assemble the screen changer, sensor, and water pipe.

9. Connectthe melt pump to the main machine.

10. Heatthemelt pump to the setting value, check if the gear shaft can rotates smoothly with your hand, if not, loose the screws on both upside cover and downside one, and use a copper bar to knock the covers to adjust it to the  right  place, then tight the screws, assemble the  nylon pins.

Attention: The principle of the melt pump relies on the self-lubricating of the melt. If there is no melt in a new melt pump, first start the machine to let the melt get into the melt pump, then start the melt pump.

Procedures to start the line:

1. Switch the swith to the manual mode, start the oil pump.

2. Press the interlock button, don’t move your hand.

3. Start the melt pump, don’t set the frequency.

4. Start the main machine, switch the potentiometer, and set the speed of the main machine.

5. Start the vertical feeder and the meter, set the speed of the meter, and start to feed.

6. Speed up the main machine according to the current.

7. When melt gets into the melt pump, switch the potentiometer, and set the speed, now, you can move your hand on the interlock button. (To ensure that the melt gets into the melt pump, observe the barrel pressure, if it starts to go up, that’s it)

8. When the melt comes out from the die, stop the meter, vertical feeder, main machine, and melt pump. Switch the switch to PLC mode, and start the machine on the PLC touch screen.
