1. During the glue spraying process of the hot melt glue machine, the glue strip is not straight when it is turned on from the beginning. , Do not hit the air pressure too high, it should be within the specified range of the hot melt glue machine manual.

2. If the glue spraying of the hot melt glue machine is stable at the beginning, and the glue path is skewed during the walking process, it can basically be judged because the pressure of the pump has leaked. You can check whether the seal ring of the pump body is damaged or not. If it is damaged, just change the sealing ring.

3.
