[0032] Referring to Figure 1 and Figure 2 , the sizing system according to the embodiment of the present application comprises a sizing pool 100 and a fluid conveying device 200.

[0033] The sizing pool 100 is provided with a first containing groove 110 and a second containing groove 120, the second containing groove 120 is arranged around the first containing groove 110, and the second containing groove 120 can receive sizing material overflowing from the first containing groove 110; the groove bottom of the first containing groove 110 and / or the groove bottom of the second containing groove 120 is provided with a sizing inlet 111 for communicating with a beating device;

[0034] The fluid conveying device 200 communicates the second containing groove 120 and the first containing groove 110, and is used for conveying the sizing material in the second containing groove 120 into the first containing groove 110.

[0035] It can be understood that one or both of the first holding tank 110 and the second holding tank 120 can be in communication with an external pulp feeding device, which can feed pulp into the pulp pool 100 to fill the first holding tank 110 with pulp, and a forming mold can enter the first holding tank 110 to absorb the pulp in the first holding tank 110 to form a wet embryo. It should be understood that the pulp feeding device continuously feeds pulp into the first holding tank 110, so that the first holding tank 110 can always be kept full of pulp, so that the liquid level in the first holding tank 110 is always kept flush with the height of the outer wall of the first holding tank 110, so that the concentration in the first holding tank 110 is constant or the fluctuation range of the concentration is small, so that the thickness of the wet embryo formed by the forming mold each time is uniform. Because the first holding tank 110 is continuously fed with pulp, the pulp in the first holding tank 110 will overflow, and the pulp overflowing from the first holding tank 110 will flow into the second holding tank 120, which surrounds the first holding tank 110, so that the pulp overflowing from all around the first holding tank 110 can enter the second holding tank 120. The first holding tank 110 and the second holding tank 120 are in communication through the fluid conveying device 200, which can convey the pulp in the second holding tank 120 back into the first holding tank 110, realizing the circulation of the pulp and avoiding the waste of the overflowing pulp.
