[0031] The limiting barrel 5 is provided with a guiding portion 5 b which is an arc-shaped structure and is used for guiding the third stirring blade 9 .

[0032] First, the staff installs the fiber pulp secondary refining device of the bobbin base paper at the position where it needs to be used, and then the staff uses an external pump to pass the fiber pulp into the mixing barrel 2, and then controls the motor 3 to drive the rotating rod 4 to rotate, the rotating rod 4 drives the connecting rod 7 to rotate, the connecting rod 7 drives the first mixing blade 13 to rotate, the connecting rod 7 drives the first clamping ring 11 to rotate, the first clamping ring 11 drives the second mixing blade 12 to rotate, that is, drives the second mixing blade 12 to rotate clockwise from the top to the bottom, the first clamping ring 11 drives the elastic member 10 to rotate, the elastic member 10 drives the second clamping ring 8 to rotate, and the second clamping ring 8 drives the second clamping ring 8 to rotate. 8 drives the third stirring blade 9 to rotate, that is, drives the third stirring blade 9 to rotate clockwise from a top-down perspective. Under the rotation coordination of the third stirring blade 9 and the second stirring blade 12, since the four third stirring blades 9 and the four second stirring blades 12 form an auger structure, the main components of the fiber pulp are cellulose, pulping medium and impurities in the wood, and the main component of the pulping medium is water or chemical solution, that is, the silk-like cellulose in the fiber pulp is driven to move downward, so that the cellulose moves downward, and the dispersed cellulose moves from top to bottom, while driving the pulping medium and impurities in the wood to move downward.

[0033] During this process, the electric slider 15 is controlled to slide upward on the electric slide rail 14 at the same time, the electric slider 15 drives the limit barrel 5 to move upward, the limit barrel 5 drives the filter screen 6 to move upward, the filter screen 6 moves upward to receive and filter part of the pulping medium and impurities in the wood, when the filter screen 6 moves close to the lower end of the third stirring blade 9, the third stirring blade 9 continues to rotate to cooperate with the filter screen 6, and at the same time, the third stirring blade 9 keeps rotating under the guidance of the guide part 5b, and the second pulping work is performed to further refine the cellulose attached to the filter screen 6, and at the same time, the cellulose on the filter screen 6 is scraped to prevent it from clogging the filter screen 6, so that the impurities in the wood in the fiber pulp are further removed. Filtration to prevent cellulose from blocking impurities in the wood. At the same time, the limiting barrel 5 approaches and contacts the second clamping ring 8, and drives the second clamping ring 8 to move upward to compress the elastic member 10. During this process, the third stirring blade 9 is further deflected by the limitation of the filter screen 6, that is, the third stirring blade 9 rotates with the rotating shaft on the second clamping ring 8 as the rotation center, but under the action of the torsion spring, the third stirring blade 9 maintains an inclined state and continues to rotate in cooperation with the guide part 5b, and then the second clamping ring 8 moves further upward and approaches the first clamping ring 11.

After the cellulose is dispersed, the motor 3 is controlled to stop running, and then the lifting ring 18 is fixed by using the external lifting equipment, and then the lifting ring 18 is lifted by the lifting equipment, and the lifting ring 18 is driven by the connecting plate 17 to move upward, and the connecting plate 17 drives the connecting rod 7 to move upward, and the connecting rod 7 drives the parts connected thereto to move upward, that is, the connecting rod 7 drives the limiting barrel 5 to rotate. The barrel 5, the second clamping ring 8, the third stirring blade 9, the elastic member 10, the first clamping ring 11, the second stirring blade 12, the first stirring blade 13 and the electric drive limit block 19 move upward, detach from the stirring barrel 2, and are hoisted to the external washing tank for subsequent work.
