The continuous progress of automatic dispensing machine processing technology is closely related to the progress and development of science and technology. Modern automatic dispensing processing applications are becoming more and more common. During the whole operation process, various problems are often encountered. There are many reasons that affect the quality of automatic dispensing processing, especially the size of the pressure needle diameter, the distance between the needle and the dispensing processing surface, the temperature and viscosity of the glue. Dispensing machine equipment how to choose a suitable and reasonable dispensing machine needle?

1, according to the type of glue, choose the right dispensing needle

Dispensing processing in the selection of needles need to pay special attention to the glue used in dispensing processing, because there are certain differences in the types of glue, the use of needles are of course different, and most of the glue used in many dispensing processing is equipped with special needles. If it is a light curing dispensing process, it is generally a black opaque vacuum configuration, and the white piston can cover the ultraviolet needle. If the ultraviolet dispensing process generally uses amber needles with white pistons, if other types of needles are used, the needles need to use opaque ultraviolet light.

2, according to the processing needs to choose their own replacement dispensing needle

When choosing a needle, practical needs need to be considered. If it is instantaneous glue dispensing processing, it is different when selecting needles. Water-based instant adhesive should use safety piston, metal lined needle should also be selected. If it is a thick instant glue, you need to choose a taper needle.

Here is how to choose the needle of the automatic dispensing machine, I hope it will be helpful to you. If the automatic dispensing machine uses unreasonable needles, it is particularly prone to non-glue or discontinuous dispensing. Therefore, this choice is very important for the entire dispensing process. Do not mix randomly to avoid needles to bring more trouble to the whole operation.
