[0031] In this embodiment, by setting the grouting device and the stirring device, grouting of the mold pit in the forming mold 3 is realized, the production efficiency is ensured, and at the same time, the fluidity of the wood pulp raw material inside the slurry storage tank 502 can be ensured to prevent it from solidifying. At the same time, the scraping plate 605 also scrapes the inner wall of the slurry storage tank 502 to avoid its adhesion to the inner wall.

[0032] Next, the working principle of the sanitary napkin core forming device will be specifically described.

[0033] As Figure 1-3As shown in the figure, during use, first pour the wood pulp raw material into the interior of the pulp storage tank 502, and then start the motor B602 to drive the stirring rod 603 to rotate, and then drive the stirring blade 604 to rotate to stir the wood pulp raw material, so as to ensure its fluidity and prevent it from solidifying.
