[0002] A glue dispensing machine is an automated machine that controls fluids and drips, coats, and fills liquids onto the surface or inside of products to achieve sealing, fixing, and waterproofing. It generally uses two-component glue.

[0003] The plunger valve on the existing glue filling machine used to handle the mixing and discharging of two-component glue relies on the metering of the pump and the transportation of the pipeline to transport the glue to the double-liquid valve, and then performs the glue opening and collecting actions to discharge and collect the glue. This valve body that relies on the metering of the pump and the transportation of the pipeline will cause glue loss, and due to the pressure loss of the pipeline, it will eventually lead to the problem of inaccurate glue discharge.

Spring valves 19 are provided in the four glue outlet holes 18. The side of the valve plate 17 away from the cylinder body 14 is fixedly connected to a cover plate 20.

[0024] In the above two embodiments, when glue is poured, glue A and glue B enter the cylinder 14 through the glue A inlet 15 and the glue B inlet 16 respectively, and the metering motor 2 is controlled to operate, and the metering motor 2 drives the driving gear 3 to rotate, and the driving gear 3 drives the driven gear 31 to rotate, and the driven gear 31 drives the screw 5 to rotate, and the screw 5 drives the lifting block 6 to move upward or downward.

The metering motor 2 drives the driving gear 3 to rotate, and the driving gear 3 drives the driven gear 31 to rotate.
