Dispensing tips for dispensers

The rapid development of all walks of life has also led to the development of many auxiliary industries, the market demand is also growing. With the development of the electronics industry, glue dispensing machine has also become increasingly hot, and it has also driven more industrial development. However, there are still a lot of tricks in using the dispenser equipment.

In the process of the dispenser operation, if the glue is used up, the presence of air will be caused in the dispensing valve.

  1. Check if the hose has passed the effective use time.
  2. If this is the case, clean the pump, and follow the relevant operating procedures.
  3. Turn off the dispenser, open the valve, and tear down the cooling sleeve(If there is one).
  4. Then remove the airhead.
  5. The next step is to remove the hose. When removing the hose, you should see if the elbow fitting is still on the dispensing valve. The premise is that there is this elbow fitting.
  6. When the hose is removed and the dispensing valve is locked to the bottom of the adapter, there will be a little cavity. If there is such a situation, you can use the glue contained in the hose to fill the cavity, then check if there are any air bubbles.
  7. When changing the hose, it depends on whether the fluidity of the glue is suitable. No bubbles should appear from the beginning to the end, because the bubbles can cause a dripping problem and an unstable amount of glue, etc.
  8. When replacing the hose, be careful not to let air enter the glue passage. If there is air remaining and you are not sure if the air is entering the pump of the dispenser through the hose, you can replace the hose with the following steps:

1) View the adapters for the link hose and dispensing valve. Mainly check if there is colloid overflow, if any, wipe it off.
2) Then reinstall the airhead.
3) Then install the hose cooling sleeve again.
4) Then close the dispenser door.
5) Finally restart the dispenser device.

It is necessary to have enough time for the glue to flow out of the dispensing head in the new hose and confirm that the pressure and speed of the dispensing valve are set according to the ideal state. The colloidal flow rate is then determined until the error of two consecutive measurements is within plus or minus 2%.
