The dispensing machine is an important link in the production equipment, intelligent dispensing technology can perform a variety of dispensing work, through the allocation of related accessories to complete high quality and efficient dispensing, dispensing needles belonging to the bottom end of the glue dispensing valve for flow of glue, in dispensing often occurs when multiple faults, such as glue brushing, dispensing needle clogging by understanding, method of preventing blockage of the dispensing needle can improve the fluency of the dispensing work.
Select the dispensing needle also may be an important factor leading to blockage of the needle, needles of different specifications will affect the quality of dispensing, dispensing needles of small volume of the plastic thin and small, normal use will be a part of the glue remaining in the dispensing needle, so the emergence of needle clogging phenomenon, if the need for a large number of the best glue choose to use large needles can fundamentally prevent internal blockage. By reducing the glue viscosity and enhancing the fluidity, it can also prevent glue from clogging. By heating the needle, it can reduce the viscosity of the internal plugging glue and achieve the effect of flowing glue.
There is no guarantee that an important reason for blocking glue is coherent when glue dispensing needle, flow to the dispensing needle if no coherent will glue all run out easily when work is stopped slowly curing causing blockage, so the dispensing consistency is very important, dispensing operator should be carried out after a period of internal delay close glue the remaining glue discharge all avoid curing, which is the effective method to prevent clogging of the dispensing needle.
When using stainless steel dispensing needles for dispensing, first of all, it is necessary to remove internal residual foreign bodies. These foreign bodies may be mixed with improper storage or air flow. If not processed in time, it is easy to cause needle blockage when dispensing.
