[0025] like Figure 1-Figure 3 As shown, a feed port 8 is provided at the top of the mixing papermaking drum 1, a discharge port 9 is provided on the outer wall of one side of the lower end of the mixing papermaking drum 1, an inclined discharge block 10 is fixedly installed at the bottom end of the mixing papermaking drum 1, and the discharge port 9 is located at one end of the inclined discharge block 10. A plug-in hole is provided in the middle position of the outer wall of the top end of the mixing papermaking drum 1, and a fixing shell 11 is provided on the outer surface of the mixing motor 201 in the mixing and stirring quick-release assembly 2. The two ends of the fixing shell 11 are fixedly connected to the mixing papermaking drum 1 through fastening bolts 12. The output end of the mixing motor 201 is fixedly connected to the mixing main rod 202. The mixing main rod 202 is plugged into the plug-in hole. The outer wall surfaces of both sides of the mixing main rod 202 are linearly symmetrically provided with arc grooves 203. A mixing auxiliary rod 204 is rotatably installed in the arc groove 203. A spring hole is provided at one end of the mixing auxiliary rod 204. A torsion spring 202 is provided in the spring hole. 05. One end of the torsion spring 205 is fixedly connected to the inner wall of one end of the arc groove 203, and the other end of the torsion spring 205 is fixedly connected to the inner wall of one end of the spring hole. A semicircular support block 206 is fixedly installed at the lower end of the stirring main rod 202, so that the staff can pour the mixed slurry of wood fiber and waste paper pulp through the feed port 8. At this time, the staff will fix the stirring motor 201 with the stirring main rod 202 on the top of the mixing papermaking drum 1, and then the staff will fix the stirring motor 201 by tightening the bolts 12. When the staff turns on the stirring motor 201, the stirring main rod 202 drives the stirring auxiliary rod 204 to rotate.

Then the staff can proceed to the next step of papermaking by grinding the fully ground slurry.
