Problems solved by technology

However, the existing dispensing head is easy to block due to the small glue outlet hole. After the blockage, the entire glue head needs to be replaced, resulting in waste
Moreover, due to production needs, the position of dispensing glue often needs to be replaced. At this time, the length of the needle needs to be changed. At present, it can only be changed by changing the glue head. waste

Abstract

The invention discloses a detachable split-type dispensing needle head which comprises a hollow bottom and a needle head made of a stainless steel material, wherein the needle head is conical; an internal thread is formed in the glue outlet end of a base; an external thread matched with the internal thread is formed in the outer wall of the glue inlet end of the needle head; the base and the needle head are connected through the internal thread and the external thread which are matched with each other, so that the base is communicated with a hollow cavity in the needle head; glue flows from the glue inlet end of the base and flows out from the glue outlet end of the needle head, namely a conical tip end; a circle of clamping boss is arranged on the outer wall of the base; at least two first parallel sections which are symmetrically arranged and are used for clamping are tangentially formed on the outer side of the clamping boss; two second parallel sections which are symmetrically arranged and are used for clamping are tangentially formed in the middle of the needle head. According to the detachable split-type dispensing needle head, the production cost can be saved, and the needle head is convenient to mount.

Description

technical field [0001] The invention relates to a detachable split glue dispensing needle, which is mainly used in the glue outlet of a fully automatic glue spraying machine. Background technique [0002] The glue outlet of the automatic glue spraying machine needs to use a dispensing needle. Considering that the viscosity of the glue used in the glue spraying equipment is different, and the thickness of the glue spraying line is different, the dispensing head used for the glue spraying equipment should be selected in terms of Note: the dispensing head must be easy to disassemble, replace and clean. Only in this way can the normal use of the machine be guaranteed and it will not be easily blocked. However, the existing dispensing head is easy to block because the glue outlet hole is small. After the blockage, the entire glue head needs to be replaced, resulting in waste. Moreover, due to production needs, the position of dispensing glue often needs to be replaced. At this ...
