[0025] When the pneumatic cylinder 3 is in operation, it will drive the round rod 4 to move to the right and squeeze the rotating rod 5, so that the rotating rod 5 rotates with the fixed block 6 as the axis, pulling the connecting rod 7 and the movable rod 8 to the left, thereby driving the quantitative barrel 9 and the cover plate 10 to move to the left, thereby achieving the purpose of quantitative addition of raw materials.

[0026] A fixing plate 11 is fixedly installed inside the connection box 2 , and the top of the fixing plate 11 is movably connected to the bottom of the cover plate 10 .

[0027] The design of the fixing plate 11 serves to limit the position of the cover plate 10 , thereby ensuring the sealing effect of the cover plate 10 on the bottom of the quantitative barrel 9 .

[0028] Among them, a rectangular plate 12 is fixedly connected to the bottom of the back of the discharge box 1, and a driven circular wheel 13 is movably installed on the left side of the top of the rectangular plate 12.

[0029] The design of the rectangular plate 12 plays a role in supporting and stabilizing the driven circular wheel 13 .
