[0023] In this embodiment, the injection mechanism 4 includes a feed through hole 2, a servo motor 3, a spiral blade 14, and a bellows fitting 16. The outer side of the feed through hole 2 is symmetrically provided with a storage tank body 1, and the bottom end of the storage tank body 1 is penetrated and connected with a bellows fitting 16. The bottom end of the bellows fitting 16 is penetrated and connected with the top of a distribution plate 6. A servo motor 3 is arranged directly above the storage tank body 1, and the output end of the servo motor 3 is connected to the top of the spiral blade 14. The spiral blade 14 is arranged inside the storage tank body 1, and the material is mixed by the spiral blade 14 to avoid material agglomeration and blockage of material discharge.

[0024] In this embodiment, the material storage tank body 1 is connected to the material guiding pipe 11 through a bellows fitting 16 penetrating through the bottom end, and the material is directly injected into the inside of the material distribution tray 6 by means of the bellows fitting 16 to complete the material separation processing of the material distribution tray 6.

[0025] In this embodiment, the material distribution mechanism 8 includes a material distribution plate 6, an electric cylinder 9, a columnar rubber plug 15, a partition panel 10, a material guide pipe 11, a side positioning groove 12 and a discharge hole 13. The bottom end of the material distribution plate 6 is provided with an electric cylinder 9, and the output end of the electric cylinder 9 is connected to the columnar rubber plug 15. The columnar rubber plug 15 is arranged on the material guide pipe 11, and the outer side of the material guide pipe 11 is provided with a discharge hole 13.
