The problem of dripping of the dispensing valve of the automatic dispenser often occurs after the dispensing valve is closed, which causes this situation. 95% of the reason is that the needle diameter of the dispenser valve is too small.

The needle equipped with the dispensing valve is too small and unsuitable, which will affect the flow of the colloid and cause back pressure, which will cause the glue to leak after the valve is closed. During the use of the dispenser, a needle that is too small will also affect the bubble ejection action of the dispenser valve.

2.Solve the method of dripping and leaking from the dispensing valve of the automatic dispensing machine

a. Dispensing and leaking of the dispensing valve, you can adjust the pressure of the pressure barrel, do not be too high, you can drive the glue, the dispensing valve can be fine-tuned; if it is a silicone rotating dispensing valve, try to reduce the size Valve response time), custom rotary dispensing valves, or replacing larger needles can solve this problem.

b. The tapered oblique needle produces less back pressure and the colloid flows smoothly. The air in the liquid will cause the glue to leak after the dispensing valve of the dispenser is closed. You can exclude the air in the liquid in advance or use a different Glue that is easy to contain bubbles, or use the gel after defoaming by centrifugation.
