[0042] It should also be noted that the worm 336 and the worm wheel 3381 mesh to drive the connecting shaft 338 to rotate, and the rotation of the connecting shaft 338 drives the cam 3382 to rotate. After the cam 3382 rotates, it slowly contacts the baffle 332 and pushes the baffle 332 to rotate clockwise. When the baffle 332 rotates clockwise, it is relatively tilted with the storage box 335, and the raw materials in the storage box 335 are discharged into the collecting hopper 33 through its discharge end. Adding the required combustion aid, adhesive, etc. to the paper scraps in the collecting hopper 33 multiple times can ensure that the additives are evenly dispersed in the raw materials, avoid agglomeration or precipitation of the additives, and gradually add the additives to avoid agglomeration of the raw materials, ensure the effect of stirring and mixing, and make the additives play a better role in the raw materials, thereby improving the reaction efficiency.
