Glue dispenser , we also call coating machine ,glue potting machine and so on . It is a flow controlling system .The automatic glue dispensing machine dispense or coat the glue on the surface or internal of the products which can be 3D/4D track . The functions including accurately positioning ,precision glue controlling ,no drawing , without leakage and so on . Glue dispense main widely use for dot , line , arc , circle track to accurately dispense glue,oil paint or other liquid to each product .
Glue dispenser suitable for fluids as follow : Solvents ,adhesives,oil paint,chemical materials,solid gum ,silicon , EMI conducting resin ,UV glue, AB glue, quick-drying glue, epoxy glue, polyurethane adhesive, sealant, hot glue, red glue, solder paste, acrylic adhesive, adhesive wear, crystal glue, glue, horn glue, instant glue, rubber, paint, enamel paint, lacquer, printing ink, paint.
1.Please put the glue into cylinder and cover with adapter ,then fixed it on the fixture.
2.Editing programs base on tracking of the products and save it .
3.Setting the gum productivity base on product and storage the parameter .
4.Select the program and test the glue for sample production, if no problem , you can start batch production .
Glue dispenser mainly including one compressed air source , one main compressed air channel, one assistant compressed air channel , one glue gun and one timing controller . Main compressed air channel set in turn with pressure regulating valve ,pressure meter ,three-port valve which end is connecting with compressed air source and the other end is connecting with flexible pipe . The assistant compressed air channel which is connected with compressed air source set in turn with governor valve and branch pipe which is connecting to atmosphere ,those lead to the branch pipe with negative pressure. In addition , The piston glue gun makes the viscose extrusion from the needles with the help of pneumatic drive and accurate control of timing controller . Meanwhile , negative pressure back to the suction and make the glue gun without any residual drawing .

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 acetone . 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 or teflon 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 .
