Drops always happened when valve closed . The reason may be low concentration of glue , big air-pressure or large diameter of needles.
Narrow needles will effect the flow of the liquid and cause back pressure . It will lead to dropping when the valve closed . Too narrow needles will effect the drainage of air when valve start to work, but it can be solved if change suitable needles .
Conical needles with less back pressure and liquid flow smoothly .
It is better to drainage of the air advance or use no-foam glue or deaeration to avoid the air cause dropping after valve closed .
The problem cause mainly because of the storage flow pressure tank or air pressure is not stable.
Inlet pressure regulating table should be set lower 10-15psi than factory minimum pressure . The pressure in pressure tank should be set upper than the middle pressure of regulating table . It should be avoided to use the pressure lower than the middle pressure of regulating table .
Control pressure of rubber valve at least higher than 60psi to assured glue evenly .
We should check the glue output speed at last . The glue is uneven if the time less than 15/1000s , the output speed more longer , the glue dispensing will be more stable .
It should be changed the pipe from 1/4 to 3/8 if the flow velocity too slowly .
The pipe is the shorter the better if no requirement .
Excessive fluid pressure and short valve opening time may lead to the air infiltration liquid . We can use the conical needles and reduce fluid pressure .
This problem is caused by heavy moisture and recycle instant glue . We should make sure to use new instant glue and wash the pipes with dry . Make sure air dry and add filter between plant air pressure and valve .
Make sure to use black pipeline.
Don't add new UV glue to old UV glue in pressure tank , we should drain off the old UV glue before pouring new UV glue into pressure tank because the UV glue will produce bubble after a period of time and lead to glue dispensing unevenly .
Normally , it may cause air problem if the needle less than NO.20 . It is better to use large steel needles or conical needles to avoid to use winding needles
It is better to use storage pressure cylinder of methybenzene toluene to self-cleaning one time for each shift . The more frequently cleaning the better .
