The hot melt glue machine manufacturer analyzes how to solve the problem of the air pump motor not being able to dispense glue!
The manufacturer of the hot melt glue machine analyzes how to solve the problem of the air pump motor not dispensing glue! If it is a newly installed machine, it may be due to vacuum in the hot melt glue circuit. At this time, please remove the nut of the hot melt glue pipe joint and let the machine run to expel the air. Once the glue dispenses normally, reattach the hot melt glue pipe to the locking joint nut.
1.First, check if there are any issues with the temperature control and heating device of the hot melt glue machine:
2.Whether the main unit of the hot melt glue machine, hot melt glue pipe, and hot melt glue gun have reached their set operating temperatures. Generally, each component has its own heating system with set temperature values. If there is no temperature in the hot melt glue gun, pipe, or main unit, it will lead to instability and inability to spray glue normally or very low spray volume.
3.If operators do not add glue in a timely manner during use, it will cause a decrease in liquid level at the suction point in the glue tank of the hot melt glue machine. Subsequently adding a large amount of new glue will cause a significant drop in temperature within the tank as it absorbs heat from newly added adhesive, leading to an increase in viscosity and poor flow characteristics making it temporarily unusable. Therefore, under normal conditions, the liquid level of adhesive in a functioning hot melt glue machine's tank should be maintained at one-fourth.
4.Whether there is regular cleaning of the adhesive tank and large filter mesh combination used with the hot melt glue machine. If not cleaned for an extended period or repeatedly heated, carbon deposits may form inside the tank. This can easily clog filters or nozzles. It is recommended to use paraffin for cleaning or use new adhesive to flush out carbon deposits.
5.Some hot melts may have quality issues due to outdated production equipment during manufacturing processes such as unstable reaction temperatures or low filtration precision that could affect their quality. Therefore, it is important to choose high-quality adhesives and manufacturers.
6.Check if there are any signs of leaking adhesive at relevant connection sealing points on the hot melt glue machine.
