Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing machines, in particular to a rotary glue dispensing two-way valve for glue dispensing machines. Background Art

[0002] Glue dispenser, also known as glue coating machine, glue dripping machine, glue spraying machine, glue filling machine, etc., is an automated mechanical equipment specially used for controlling fluid. It achieves precise positioning and precise glue control by dripping and applying fluid on the surface or inside of the product to ensure no drawing, no glue leakage, and no glue dripping. Glue dispenser can be used in a variety of industries, such as lighting, solar photovoltaic, automobile, industrial electrical, electronics, construction engineering, handicrafts and medical technology.

[0003] Glue dispensing machines can be divided into many types, including single-component glue dispensing machines, two-component glue dispensing machines and non-standard glue dispensing machines. Among them, two-component glue dispensing machines can be divided into semi-automatic two-component glue dispensing machines and fully automatic two-component glue dispensing machines. In addition, there are many sub-types such as desktop glue dispensing machines, floor-standing glue dispensing machines, spray-type automatic glue dispensing machines, and conductive glue automatic glue dispensing machines.

[0004] However, conventional dispensing machines mainly use the input gas to drive the piston to push the colloid out, and the dispensing is usually stopped by using a spring reset. There is a certain delay in the spring closing, so the dispensing machine needs to calculate the advance amount when closing, otherwise a small amount of colloid will flow out when dispensing on small parts. When dispensing parts at different positions or areas, the advance amount needs to be recalculated. In order to solve this technical problem, the utility model proposes a rotary dispensing two-way valve for a dispensing machine. Utility Model Content
