The gear pump hot melt glue machine discharges the hot melt glue through the rotation of the gear pump. If the pump flow is insufficient, it will affect the glue spraying effect of the hot melt glue machine, thereby affecting the product quality. Therefore, it is necessary to solve the problem of insufficient pump flow in time. The following reasons are roughly analyzed:
1. The reflux valve may be damaged. The adjustment screw can be rotated counterclockwise to reduce the pressure. The hot melt glue machine or the adjustment screw can be rotated clockwise to increase the pressure of the throat to detect whether the glue output has changed:.
2. It is possible that the hot melt glue spray machine has not been regularly maintained, and there are carbide impurities in the glue tank, causing the entire glue delivery channel to be blocked.
3. Check whether the glue suction amount at the inlet of the gear pump is normal.
4. There is glue leakage in the glue tank.
5. Check whether the gear pump speed is normal. If the gear pump speed is too low, the glue output will be small.
The automatic hot melt glue machine is a hot melt glue carbon cloth composite machine that automatically melts and sprays glue. It can be used alone or in conjunction with conveyor lines, manipulators, box sealing machines, mattress machines, filter machines, woodworking machines, coating machines, etc. In this way, the glue spraying process does not require manual labor at all. A hot melt glue machine can save 3-5 people and recover the machine investment cost in a short time. The use of an automatic hot melt glue machine can well control the glue spraying amount and time, which saves at least 30% of the glue hot melt glue gun, and can also improve production efficiency and save raw material costs for the enterprise.
Hot melt glue machines and cold glue machines are both used to spray adhesives, but hot melt glue machines use solid glue blocks, glue particles, and glue strips that need to be heated and melted into liquids before applying glue, which is hot melt glue. This kind of glue has strong viscosity, short bonding time, no odor, strong water resistance and heat resistance, and fast glue drying. Therefore, hot melt glue can avoid cold glue mold, slow glue drying, deformation, bubbling and other three-axis glue machine phenomena, and will not corrode the machine.
The products made by the hot melt glue machine are beautiful and of good quality, which greatly reduces the occurrence of defective products. Therefore, compared with cold glue, hot melt glue has a wider range of uses. It is environmentally friendly and safe, has no harm to the human body, and its high viscosity improves product quality and appearance. If you choose hot melt glue, you must have a hot melt glue machine. The hot melt glue machine is one of the indispensable mechanical equipment for manufacturers using hot melt glue.
