Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, specifically an adhesive coating nozzle. Background Technology

[0002] A glue applicator, also known as an AB two-component glue applicator, is an automated machine that controls fluids and applies liquids dropwise, coats, or fills them onto the surface or inside of a product to achieve functions such as sealing, fixing, and waterproofing. It typically uses two-component adhesives.

[0003] For conventional glue application, the inner wall of the dispensing head is cylindrical, and the cross-section of the dispensing glue is circular. However, for glue application processes that involve applying glue to a surface as a sheet with a certain width, existing dispensing heads cannot accomplish this and meet the needs of practical use. Furthermore, the glue flows too quickly in the mixing chamber, resulting in poor mixing performance.

[0004] In addition, traditional mixing tubes are mostly one-piece designs. After repeated use, the residual adhesive inside is prone to solidification, which can lead to obstructed adhesive flow or even no adhesive being dispensed. Utility Model Content
