The introduction and export of the slurry are carried out simultaneously, facilitating the full mixing of the slurry and additives. At the same time, since the position of the fixed cylinder 501 is fixed and the rotating tank 506 slidingly cooperates with the reciprocating spiral chute 502, the rotating tank 506 drives the rotating tank 506 to reciprocate and rotate along the axis of the fixed cylinder 501 by slidingly cooperating with the reciprocating spiral chute 502 and the rotating tank 506 slidingly cooperating with the cross bar 505, so that the two rotating tanks 506 move closer to or away from each other while rotating, facilitating the efficient mixing of the slurry and additives, and avoiding the fixed one-way stirring of the slurry and additives inside the mixing tank 101; In addition, the cross bar 505 rotates and scrapes the slurry adhering to the inner wall of the end of the mixing tank 101 by connecting with the second scraper 511, improving the utilization rate of the slurry, and at the same time, avoiding the slurry from accumulating on the inner wall of the end of the mixing tank 101 and affecting the quality of subsequent slurry mixing; Wherein, the number of the feed ports 508 is the same as the number of the discharge ports 510.

At the same time, the rotating plate 503 drives the rotating tank 506 to rotate synchronously by connecting with the cross bar 505 and the cross bar 505 being slidably matched with the rotating tank 506. Since the position of the fixed cylinder 501 is fixed and the rotating tank 506 is slidably matched with the reciprocating spiral chute 502, the rotating tank 506 drives the rotating tank 506 to reciprocate and rotate along the axis of the fixed cylinder 501 by being slidably matched with the reciprocating spiral chute 502 and the rotating tank 506 being slidably matched with the cross bar 505. The rotating tank 506 drives the rotating cylinder 602 to reciprocate along the axis of the cross bar 505.

By the rotation of a number of second stirring paddles 603, the slurry and additives inside the rotating tank 506 can be stirred for the second time. At the same time, the slurry to be led out from the discharge port 510 is stirred again, improving the mixing effect of the slurry and additives. By the rotation of a number of crushing knives 604, the agglomerated or too long raw materials in the slurry can be cut, contributing to the efficient and uniform mixing of the slurry and additives, effectively avoiding the phenomenon of color difference or performance fluctuation on the surface of the paper, and improving the use effect of the subsequent household paper.
