1. Dispensing glue gun dispensing valve leaking
Such situations often occur after completion of related to the dispensing valve.
95% of such cases because of too small diameter due to the use of needles.
Small needles will affect the flow of liquid caused by back pressure leading to completion of the formation of plastic drip valve related phenomena too small when the needle will also affect the exhaust with a larger needle can be as long as the replacement to solve this problem.
Conical inclined needle back pressure generated at least, most smooth liquid flow.
Liquid off the air in the plastic valve after completion will have trickle down phenomenon, it is best preclude liquid air, is not easy to use with bubble gum.
2. Dispensing glue gun, a glue dispensing valve size inconsistency
When the glue is inconsistent with the main cylinder for the storage of fluid pressure or air pressure generated by instability.
Regulator inlet pressure should be set at the minimum pressure is low than the factory 10 to 15psi. Pressure cylinder pressure should be used over the middle between Regulator pressure should be avoided among the low-pressure part of the range of pressure gauges.
Rubber valve control pressure should be at least 60psi or more to ensure that the plastic stability.
Finally, it should check out the glue time. If less than 15/1000 cause the plastic instability seconds. The glue time to grow more rubber more stable.
3. Flow rate is too slow
If the slow flow rate should be piping from 1 / 4 "to 3 / 8."
Lines need to be as short as possible without
4. Flow inside the bubble
If too much fluid pressure valve with the opening short time there may be infiltration of the liquid air. Reduce the use conical inclined fluid pressure in the needle.
5. Instant glue (Quick Adhesive) in connection `and` rubber valve on the pipeline plug
Such cases mainly due to excessive moisture or repeat used instant glue. Be sure to use fresh air should be determined instant glue complete plant drying and pneumatic valve systems with adhesive to install filters. Above method is still valid if , nitrogen should be used.
6. UV adhesive (UV-curing adhesive)
Sure to use black pipe.
Do not directly add to the pressure tube UV adhesive glue on the old UV. First let go of the original UV glue, UV glue and then glue into the air pressure cylinder. Cylinder with UV glue is often over a period of time will produce bubbles caused the plastic instability.
7. Needles
Generally speaking, smaller than 20 needles may generate air flow problems --- drip or sag. To make use of large numbers generally conical metal needles or needle inclined. Avoid the use of bypass or Teflon needle s.
8. Epoxy resin cleaning
If possible, try to use ordinary toluene each storage cylinder pressure cleaning time, always wash the better.
