A suspension type suction filtration forming method and suction filtration forming device (2) for plant fiber molding forming. The process of the suction filtration forming method is: 1) a suction filtration forming die (2.1) moves vertically downwards from a set height and enters into slurry in a slurry tank (1) to carry out suction filtration forming; 2) the suction filtration forming die (2.1) drives a wet blank to move vertically upwards to leave the liquid level of the slurry tank (1), and stops moving after rising to a certain height; (3) the wet blank in the suction filtration forming die (2.1) is sent out and delivered to the next procedure to undergo drying; and (4) step (1) and step (3) are repeated in cycles, so that plant fiber molding forming is continuously carried out.

Disclosed are a wet blank transfer method and a wet blank transfer device for use in plant fiber molding. The wet blank transfer method comprises: forming a slurry into a wet blank for a finished product using a suction forming mold (1.1), and using a wet blank transfer mold (2.1) to suction the wet blank from the suction forming mold (1.1) and lift the wet blank up out of the suction forming mold (1.1). A slide rod (2.3) is disposed above the suction forming mold (1.1). The wet blank transfer mold (2.1) is fixed at an end of the slide column (2.3), or the wet blank transfer mold (2.1) is fixed to an end of the slide column (2.3) via a wet blank transfer mold mounting plate (2.2). The slide rod (2.3) drives the wet blank transfer mold (2.1) to move linearly up and down. Two or more transfer mold linear guide rails (2.4) are fixed to the slide column (2.3), and transfer slide blocks (2.5) are fixed to an upper frame (3). The slide rod (2.3) can slide vertically through the slide blocks (2.5) by means of the transfer mold linear guide rails (2.4). The present invention enables the wet blank transfer mold (2.1) to be moved over a large vertical distance while ensuring highly precise movement, and enables accurate height positioning of the wet blank transfer mold (2.1).

Disclosed is a full-automatic method for manufacturing plant-fiber molding products and margin trimming and molding machines. The invention achieves functions: wet semi-finished product forming, hot press mold solidifying, and automatic margin trimming. The full-automatic method is as below: pulps are continuously made into wet semi-finished products by means of a suck-filter forming device, which is alternatively fed into hot-press molds of the left hot-press mold solidifying device and the right hot-press mold solidifying device after being heated to a certain temperature in hot-press molds for hot-press drying and solidifying. The dried and solidified products fall into the left positioning collecting tray and the right positioning collecting tray respectively from the left hot-press top mold and the right hot-press top mold, and are positioned therein. The full-automatic plant-fiber molding, mold solidifying and margin trimming machine includes a forming and solidifying device, a transfer device and a margin trimming device.
