[0042] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0043] Currently, in the related art of pulp processing, first, a forming machine is used to adsorb and form pulp fibers, and then a transfer machine is used to transfer the pulp product.

[0044] During the process of transferring the product by the transfer machine, if the heights of the forming machine and the transfer machine are not adjusted properly or over time, a cyclic error will occur, causing the transfer machine to jam. As a result, the distance between the forming machine and the transfer machine becomes larger, there is a gap during transfer vacuum, and the pulp product cannot be sucked away. In the whole process, problems such as the product not being transferred out or the product being crushed will occur, leading to an increase in the unqualified rate of the product and wasting time and manpower.

[0045] Please refer to Figures 1 - 4 , this embodiment provides a pulp mold device 1000, a pulp mold system 2000, and a method for using the pulp mold system 2000, which can effectively improve the above-mentioned technical problems, improve the production qualification rate of pulp products, and save time and manpower.

[0048] Please refer to Figure 2 , the pulp mold device 1000 includes a transfer mold body 100, a forming mold body 200, a first adsorption assembly 300, and a second adsorption assembly 400.

The forming surface 210 is provided with adsorption holes 212 communicating with the negative pressure chamber 130. The first adsorption assembly 300 communicates with the transfer die body 100. The first adsorption assembly 300 is used to generate negative pressure in the negative pressure chamber 130 when the forming die body 200 descends into the pulp pool 3000, so that the liquid in the mixture in the pulp pool 3000 enters the negative pressure chamber 130 through the adsorption holes 212, thereby enabling the pulp in the mixture to be formed on the forming surface 210 of the forming die body 200. The second adsorption assembly 400 communicates with the transfer die body 100. The first adsorption assembly 300 and the second adsorption assembly 400 are spaced apart and arranged on the transfer die body 100.

[0049] The second adsorption assembly 400 is used to generate negative pressure in the negative pressure chamber 130 during the transfer process of the forming die body 200, so that the liquid between the transfer die body 100 and the forming die body 200 is discharged through the second adsorption assembly 400.

When the first adsorption assembly 300 generates negative pressure on the negative pressure chamber 130, the liquid in the mixture can also enter the negative pressure chamber 130 through the adsorption holes 212 on the bumps 211, so that the pulp in the mixture is adsorbed and molded outside the bumps 211.
