A pulp molding machine, a pulp molding process and a paper-shaped article made thereby are provided. The pulp molding machine comprises a pulp-dredging stage, a first pre-compression forming sub-stage, a second pre-compression stage, a compression thermo-forming stage and an edge-cutting stage. The pulp molding process comprises the steps of a pulp-dredging step, a first pre-compression forming step, a second pre-compression forming step, a compression thermo-forming step and an edge-cutting step. The pulp molding machine the pulp molding process can drain off water or vapor from a wet pulp more efficiently and shorten the cycle time of the pulp molding process due to the extra pre-compression sub-stage. The paper-shaped article made thereby has a greater smoothness and structural strength than conventional paper-shaped product. |

1. A pulp molding machine, comprising:
a machine frame body; a pulp-dredging stage disposed on the machine frame body, comprising a paper slurry tank, a first upper mold, a first lower mold and a first driving device, wherein a wet pulp is dredged up by the first lower mold from the paper slurry tank, and then the dredged wet pulp is applied a first pre-compression sub-stage by and between the first upper mold and the first lower mold, to form a first semi-finished product; a second pre-compression stage disposed, adjacent to the pulp-dredging stage, on the machine frame body, comprising a second upper mold, a second lower mold and a second driving device, wherein the first upper mold is moved by the first driving device from the first pre-compression sub-stage of the pulp-dredging stage to the second pre-compression stage, accompanying with conveying the first semi-finished product to the second pre-compression stage, the first semi-finished product is compressed by and between the second upper mold and the second lower mold, to form a second semi-finished product; a compression thermo-forming stage disposed, adjacent to the second pre-compression stage, on the machine frame body, comprising a third upper mold, a third lower mold and a third driving device, wherein the second upper mold is moved by the second driving device from the second pre-compression stage to the compression thermo-forming stage, accompanying with conveying the second semi-finished product to the compression thermo-forming stage, the second semi-finished product is thermo-compressed by and between the third upper mold and the third lower mold, to form a third semi-finished product; and an edge-cutting stage comprising a chopper, and disposed on the machine frame body, adjacent to the compression thermo-forming stage, wherein the third upper mold is moved by the third driving device from the compression thermo-forming stage to the edge-cutting stage, accompanying with conveying the third semi-finished product to the edge-cutting stage, the edge-cutting stage make the chopper cutting superfluous edges of the second semi-finished product to form a finished product. |
