Machine always drops resin Drops always happened when valve closed . The reason may be lowconcentration of glue , big air-pressure or large diameter of needles Narrow needles will effect the flow of the liquid and cause backpressure . lt will lead to dropping when the valve closed . Too narrow needles will effect the drainage of air when valve start to work, but itcan be solved if change suitable needles .
Conical needles with less back pressure and liquid flow smoothlyt is better to drainage of the air advance or use no-foam glue ordeaeration to avoid the air cause dropping after valve closed
Glue dropping not evenly
the problem cause mainly because of the storage flow pressure tankor air pressure is not stable.
Inlet pressure regulating table should be set lower 10-15psi thanfactory minimum pressure . The pressure in pressure tank should beset upper than the middle pressure of regulating table . lt should beavoided to use the pressure lower than the middle pressure ofregulating table .
Control pressure of rubber valve at least higher than 60psi to assuredglue evenly .
We should check the glue output speed at last . The glue is uneven ifthe time less than 15/1000s , the output speed more longer , the gluedispensing will be more stable .
