Semi-dry-pressing plant fiber molding machine and molding method

Abstract

The invention discloses a semi-dry-pressing plant fiber molding machine and a molding method. The molding machine comprises a rack which is provided with a wet blank transfer device, hot press forming devices symmetrically arranged on the left side and the right side of the wet blank transfer device, and a slurry fishing device arranged under the wet blank transfer device. The wet blank transfer device comprises a support, a wet blank transferring mold arranged on the support and a first lifting mechanism used for driving the wet blank transferring mold to ascend and descend along the support. The rack is further provided with a guide rail in the left-right direction, wherien the guide rail is provided with a sliding block capable of sliding along the guide rail and a driving mechanism used for driving the sliding block to slide; and the sliding block is fixedly connected with the support. The water content of the wet blank in the production process can be reduced, so that the influence of incrustation and slurry scraps on the hot-pressing lower die and the rack is reduced, the machine starting rate is improved, and heat energy consumption is reduced; and the wet blank transferring mold can move left and right to transfer the wet blank, and the hot-pressing lower die is fixed, so that the slurry tank is prevented from being polluted.

Description

technical field [0001] The invention relates to the technical field of plant fiber molding equipment, in particular to a semi-dry pressing plant fiber molding machine and a molding method. Background technique [0002] The existing plant fiber molding machine has two kinds of dry pressing and wet pressing. The dry-pressed plant fiber molding machine uses a cold-press upper mold and a suction filter mold to close the mold, extrude the wet embryo, then dry (or dry) the wet embryo, and then carry out molding and shaping to produce products. The production capacity is not high, the surface of the produced product is rough, the wall thickness is thick, and the aesthetics is not good. [0003] During the production process of the wet pressing plant fiber molding machine, the wet embryo transfer mold descends first, and then closes with the suction filter mold in the slurry tank below, and the wet embryo is formed. The moisture content of the wet embryo is high, and the wet embryo...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the high moisture content of the wet embryo in the production process, the vent holes of the hot-pressed lower die are easily blocked by scale and slurry debris, and the hot-pressed lower die must be removed frequently for through-hole washing; During the mold closing process with the hot-pressed lower mold, there will be slurry debris discharged from the outside of the mold with water vapor and fly to machine parts such as the frame, causing pollution, and the machine needs to be cleaned frequently

[0005] (2) High moisture content of wet embryo will increase heat energy consumption

[0006] (3) When the hot-pressing lower die moves to the bottom of the wet embryo adsorption mold, it is located directly above the pulp tank, and it is easy to drop oil, iron filings and other impurities into the pulp tank, thereby polluting the pulp tank and reducing the qualified rate of products
