A dredging system for forming wet paper shape is introduced, which comprises a pulp tank, a molding assembly, at least one suction device and at least one water-absorption material. The pulp tank is used to store paper slurry therein. The molding assembly is used to dredge up the slurry from the slurry tank and make the slurry to form at least one wet pulp body layer between the molding assembly. The at least one suction device is used to quickly draw out the water and/or moisture from the at least one wet pulp body layer. The at least one water-absorption material is disposed between the molding assembly and absorbs the water and/or vapor from the at least one wet pulp body layer to accumulate the release of the water and/or vapor upon matching of the molding assembly, so as to raise a paper shape production yield ratio.

Description

Slurry system and wet paper-plastic products for wet paper forming

The present invention relates to a slurry system and a wet paper-plastic product for wet paper forming, in particular for forming a wet paper-plastic product.

In the slurry processing of the existing molding technology for producing wet paper-plastic products, the slurry tank is used for storing pulp, and the components of the pulp include, for example, plant fragments, various fibers, water, and other raw materials, and the like, and then a mold in a mold assembly is utilized. The descent is immersed in the sump, and the pulp is lifted up from the sump to form a wet paper body or a finished product on the mold.

How to effectively and quickly reduce the moisture or moisture content of the wet paper body during mold clamping of the mold assembly has a considerable influence on subsequent processes. For example, when the wet paper embryo body is released from the mold, the moisture or water content contained in the wet paper embryo body is too high, and the following problems may occur: 1. The structure of the wet paper embryo body It is easy to collapse or permanently deform; 2. It takes a lot of energy to dry the wet paper body; and 3. The wet paper body cannot be completely dried to form a better wet paper product. In particular, when the groove of the wet paper body has a large transverse section width When the bridge is between 0 and 8 mm, the bridging phenomenon often occurs, and the structure of the wet paper embryo body is easily broken or permanently deformed.

Therefore, there is an urgent need to provide a slurry system for wet paper forming to solve the above problems.

Please refer to FIG. 1 and FIG. 2 . FIG. 1 is a perspective view of a mold assembly for wet paper forming according to a first preferred embodiment of the present invention. 2 is a schematic cross-sectional view showing the structure of a slurry system 100 for wet paper forming in accordance with a first preferred embodiment of the present invention. The slurry system 100 includes a slurry tank 175, a mold assembly 118, a suction device 190, and a water absorbing material 180. The slurry tank 175 is used to store the pulp 177. The mold assembly 118 includes an upper mold 140 and a lower mold 130.

As shown in FIG. 1 and FIG. 2 , the lower mold 130 forms a first surface 135 , a recess 110 , and at least one first through hole 120 , wherein the recess 110 and the at least one first through hole 120 On the first surface 135, in the embodiment, the at least one first through hole 120 is a plurality of first through holes 120, and is further distributed around the inner or inner wall surface of the groove 110, and the groove 110 is The quantity is not particularly limited, and the manufacturer can increase or decrease according to actual needs. The upper mold 140 defines a second surface 145, at least one protrusion 150 corresponding to the groove 110 and at least one second through hole 125, wherein the protrusion 150 and the at least one second through hole 125 are located therein.
