[0002] In the glue industry, there is a kind of two-component glue. Glue A and glue B need to be mixed together to achieve the solidification effect. When dispensing, a dispensing valve is usually used to mix and output the glue.

[0003] When mixing the two kinds of glue, the prior art dispensing valve usually adopts a dynamic mixing method, and then stops the glue by installing a separate cut-off needle. This method uses a motor to drive the screw to rotate to achieve glue mixing, and cannot perform static glue mixing. It is costly, occupies a large working space, is inconvenient to load and unload, and is not conducive to improving the overall automation level of the dispensing system and the efficiency of dispensing. In addition, if the method of coaxially arranging the screw and the cut-off needle is used, the volume of the glue mixing channel will be increased, causing the glue to stay in the mixing channel for a longer time, resulting in the loss of glue drying.
