The driving motor 1 is provided with two groups. A transmission shaft 17 is connected to the bottom of the driving motor 1. A coupling 11 is connected to one end of the transmission shaft 17. A fixing frame 4 is installed on the outer wall of the bottom of the driving motor 1. A mounting frame 7 is detachably installed at the bottom of the fixing frame 4. A stator 10 is detachably installed at one end of the mounting frame 7. A threaded rod 6 is provided on the inner wall of the stator 10. The threaded rod 6 is adapted to the stator 10. One end of the threaded rod 6 is connected to the coupling 11. A connector 5 is connected to one side of the mounting frame 7. A mixing bin 9 is provided on one side of the stator 10. Two groups of stators 10 are respectively connected to the mixing bin 9. A quick connector 8 is connected to the bottom of the mixing bin 9.

The glue liquid is delivered by the rotation of the threaded rod 6. Different glue liquids are added into the two groups of stators 10 and delivered to the mixing chamber 9 for mixing. The glue dispensing head connected to the quick connector 8 discharges the glue for glue dispensing. The driving motor 1 can control the threaded rod 6 to reverse after glue dispensing is completed, and the residual glue at the glue dispensing position can be sucked back to prevent dripping. The stator 10 and the threaded rod 6 can be disassembled and replaced to adjust the delivery amount of the glue liquid, thereby adjusting the mixing ratio.

After the glue liquid is added, the rotating motor 14 drives the rotating shaft 21 and the paddle 22 to rotate. The paddle 22 rotates to stir the glue liquid, which can make the glue liquid fully mixed, while avoiding the generation of sediment and preventing the glue liquid from solidifying.

[0038] In order to filter when adding glue, Figure 3 As shown, a filter screen 19 is detachably mounted on the inner wall of the addition port 15;

[0039] When the glue liquid is added into the mixing chamber 13 through the adding port 15 during use, the glue liquid is filtered through the filter screen 19 to avoid the mixing of foreign matter and prevent blockage during glue delivery.
