[0001] The utility model relates to epoxy resin glue coating technology field especially relates to a kind of for epoxy resin glue extrusion mechanism. BACKGROUND

[0002] Epoxy resin glue is the thermosetting adhesive based on epoxy resin, and three-dimensional network structure is formed by curing agent crosslinking, with high strength, chemical resistance and insulating property etc. Heterogeneous materials such as metal, ceramic, glass, plastic can be bonded, with high strength and good durability, also resistant to grease, acid and alkali and other corrosive media, with high electrical insulation strength, so it is widely used in many fields.

[0004] At present, the extrusion head of various epoxy resin glue extrusion devices is generally fixed in diameter, so the amount of extruded epoxy resin glue is also fixed. In standardized and automated production, the process is standard, so this fixed-diameter epoxy resin glue extrusion device is needed. However, in many manual operations, sometimes large quantities of glue need to be coated, and sometimes fine coating or dispensing is needed, so the fixed-diameter epoxy resin glue extrusion device is difficult to meet multiple needs.

[0005] Although the diameter of the extrusion head is too large, it can quickly extrude epoxy resin glue for large-scale coating, but it is difficult to perform fine operation. Although the diameter of the extrusion head is too small, it is convenient for fine operation, but the extrusion rate of epoxy resin glue is slow, and the efficiency is low when a large amount of glue is coated. Therefore, workers need to prepare multiple epoxy resin glue extrusion devices or multiple extrusion heads when working manually, and replace them when needed. This not only requires more accessories or devices, increasing costs, but also makes workers more troublesome and affects efficiency. SUMMARY

Although the caliber of the extrusion head is too large, it can quickly extrude the epoxy resin glue to carry out a large number of glue application, but it is difficult to carry out fine operation. While the caliber of the extrusion head is too small, it is convenient to carry out fine operation, but the extrusion rate of the epoxy resin glue is slow, and the efficiency is low when a large amount of glue is applied. Therefore, the extrusion head 101 is designed, which is installed at the front end of the equipment. The equipment can be a glue filling machine, a glue injection machine, a glue dispensing machine and the like.
