How to solve high precision dispensing needle clogging?

Dispensing needle is the dispensing machine must be used in the dispensing processing of dispensing consumables, the reason is called consumables, because in the dispensing processing, many dispensing needles are disposable. Therefore, it is difficult to completely avoid the phenomenon of dispensing needle blockage, but through the correct operation method, it can effectively reduce the phenomenon of needle blockage.
The plugging phenomenon of dispensing needles is mainly related to the type of glue and dispensing processing operation. For example, hot melt glue uses all stainless steel dispensing needles, and the glue can be melted by heating, so as long as the heater maintains a certain temperature, the needle plugging phenomenon will not occur.
If it is the use of fast drying glue dispensing machine dispensing processing products, because the fast drying glue is fast curing at room temperature, when the operation of the dispensing machine is interrupted, it is easy to plug the needle, at this time to reduce the needle plugging phenomenon is to maintain the consistency of dispensing.
