Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing machines, in particular to a glue dispensing machine which is convenient for replacing a glue dispensing needle. Background Art

[0002] A glue dispenser is a machine used to apply glue to the surface of a product. It usually consists of a control system, a glue supply system, and a glue dispensing head. The glue dispensing machine uses various techniques such as jetting, dripping, coating, and coating to accurately apply glue to products that need to be bonded, sealed, or wrapped. Glue dispensing machines are widely used in industries such as electronics, automobiles, medical, and aerospace. They can improve production efficiency, ensure product quality, and save glue usage. During the use of the glue dispensing machine, as the use time increases, the glue dispensing needle will become blunt due to friction and wear, resulting in poor glue dispensing effect, and the glue dispensing amount and shape cannot be accurately controlled, resulting in the need to replace the glue dispensing needle. However, some existing glue dispensing machine needles are usually connected and fixed to the glue dispensing machine by screws, so it takes a lot of time to replace the glue dispensing needle. Therefore, this problem needs to be solved. Utility Model Content
