How to avoid blockages in the production process of automatic dispensing machines?

The phenomenon of clogging of dispensing needles is mainly related to the type of glue and dispensing processing operation. In the operation of automatic dispensing machines, the dispensing needles may sometimes become clogged due to the characteristics of the glue and dispensing processing technology. If glue is used with a low viscosity, it is not easy to solidify and needle blockage is also less likely to occur; So how to prevent clogging of the needle of the automatic dispensing machine?

Firstly, increasing the temperature can prevent needle blockage

For example, hot melt glue uses all stainless steel dispensing needles, and the glue can melt as long as it is heated, so as long as the heater is heated to a certain temperature, there will be no needle blockage phenomenon.

Secondly, maintaining the continuity of dispensing can prevent needle blockage

If quick drying adhesive is used to process dispensing products, it will quickly cure at room temperature. If dispensing is interrupted during the dispensing process, it is easy to cause needle blockage, so the continuity of dispensing should be maintained.

Thirdly, when not using glue, it is necessary to remove and store the glue to prevent needle blockage

For example, AB glue has a relatively slow curing speed and does not cause blockage so quickly. However, if left unattended for a long time, blockage may still occur. Therefore, it is necessary to remove the mixing nozzle and store the glue to avoid blocking the entire dispensing needle.

Fourth, use the needle of the nano coating dispensing machine

The coating needle of the dispensing machine launched by JEENOCE is made of imported stainless steel, with high precision, wear resistance, and long service life. The internal conical design can prevent material blockage and hardening in the step section, maintaining high material fluidity.

The solution may vary depending on the glue used in production and the process used. Therefore, measures need to be taken according to the actual situation to prevent clogging of the dispensing needle and ensure production efficiency.
