Description and application of specifications of long dispen

writer:点胶设备 time:2019-04-25 11:55 clicks:
The function of long needle for dispensing glue is the same as that of ordinary needle for dispensing glue. Its particularity lies in that the length of needle tube makes the flow of glue uniform and stable and ensures the accuracy. The specifications of long needle made of metal materials are mostly between 144 and 344. Because of its good auxiliary function, it can help automation equipment to improve the accuracy of dispensing glue, so it has a better effect in the links of infusion applicator glue coating and cover plate glue Result: The long needle for dispensing can be connected to the syringe or the rubber valve to assist the dispensing. The manufacturer should contact the dispensing needle manufacturer if the specifications of the long needle are diversified.

Recommendation of Specifications and Numbers Suitable for Precision Production
 
As mentioned before, the specifications of long needles are between 144G and 34G, and the higher the specifications, the better the effect of gumming accuracy. According to the user's use, for example, the number of long needles which should be selected for gumming infusion device is higher, and the needles which meet the specifications are suitable for dispensing gum. Therefore, the specifications of long needles which are used for gumming infusion device are about 30G, which can be used for gumming infusion device. The outer sleeve of the dispensing needle is uniformly glued to make its bonding strength moderate. The dispensing needle manufacturer suggests that the specifications of the long dispensing needle be suitable. If it is too fine, it will also affect the quality and effect of dispensing. The following is an example of the links of covering plate gluing.

Particularity of Glue Coating for Different Covers
 
Cover glue coating mostly refers to the bonding of the cover plate of the outer end of the battery after uniform glue coating. It needs a long needle for dispensing glue to provide stable and smooth auxiliary glue supply. As for the precise glue control function of the cover plate glue coating and the infusion device glue coating, the size of the long needle selected is high precision, and some special cover plate edges need uniform and full coverage. Because the incomplete filling of glue volume will cause the incomplete bonding surface and directly affect the stability and strength quality of the cover plate, the size of the long needle should be re-selected for the larger battery cover plate gluing. The dispensing needle manufacturer suggests that the accuracy of about 30G should meet most of the industry production.
