[0034] In the present invention, when the cylinder air inlet receives compressed air, the cylinder piston is pushed, the lever group drives the ejector pin to leave the nozzle opening, and the nozzle opens to discharge the medium. When the cylinder exhaust hole opens, the cylinder piston returns under the action of the cylinder spring, the lever group drives the ejector pin to return and block the nozzle opening, and the mixer switches to a circulation state.

[0035] The present invention also provides a method for using the epoxy resin glue mixer, comprising the following steps:

[0036] S1, discharging state: the lever group drives the ejector to leave the nozzle through the lever action and withdraw to block the return port. At this time, the medium enters the material valve cavity through the feed port, enters the mixing cavity through the nozzle, and finally enters the mixing mechanism for high-speed mixing;

[0037] S2: Circulation state: The lever group drives the ejector pin to hold the nozzle through the lever action. At this time, the medium enters the valve cavity through the feed port, and then flows out from the return port through the valve cavity, forming a medium circulation.

[0038] Preferably, the mixer of the present invention can be used to prepare epoxy resin glue.

[0039] Preferably, when the epoxy resin glue includes four components, the present invention can accurately control the opening and closing of the material valve according to the pneumatic device, control the four epoxy resin glue raw material media to enter the mixing cavity through the four material valves according to the proportion, and achieve mixing under the operation of the mixing mechanism to obtain the epoxy resin glue.
