Wet blank transfer method and wet blank transfer device for plant fiber molding formation

Abstract

The invention relates to a method and a device for manufacturing a plant fiber product comprising paper pulp in a molding formation mode. The wet blank transfer method for plant fiber molding formation comprises the following steps: (1) a slurry is processed by a suction filtration forming mold to form a wet blank for the product, and the wet blank transfer mold sucks up the wet blank from the suction filtration forming mold and upwards moves the wet blank out of the suction filtration forming mold; (2) a sliding column is arranged above the suction filtration forming mold, the wet blank transfer mold is fixed at one end of the sliding column, or the wet blank transfer mold is fixed at one end of the sliding column through a wet blank transfer mold mounting plate, and the sliding column drives the wet blank transfer mold to linearly move up and down; and (3) two or more transfer mold linear guide rails are fixed on the sliding column, the transfer sliding block is fixed on an upper rack, and the sliding column can vertically slide up and down on the transfer sliding block through the transfer die linear guide rails. The method and the device can ensure the high moving precision when the wet blank transfer mold moves up and down for a long distance, and make the wet blank transfer mold accurately positioned in the height direction.

Description

AI Technical Summary

Problems solved by technology

[0004] 1. The up and down movement of the wet billet transfer die is driven by an oil cylinder. There is a problem, that is, when the piston seal ring of the oil cylinder is worn out, the oil cylinder will leak internally, causing the wet billet transfer die to slide out of control, and the piston seal ring is in the working process. Wear and tear is inevitable, so this has brought a lot of trouble to the production and so far the industry has not been able to solve it

[0005] 2. The wet billet transfer mold cannot be accurately clamped with the suction filter forming mold, and the mold clamping error is very large each time, which often causes the wet billet to be torn, or the wet billet cannot be transferred to the wet billet transfer mold for normal transfer

[0006] 3. When the wet blank transfer mold and the suction filter forming mold are clamped, the impact is too large, and the vertical positioning of the wet blank transfer mold is difficult to achieve

[0007] 4. When the wet billet transfer mold transfers the wet billet to the hot-pressing mold, the relative distance between the wet billet transfer die and the hot-pressing die cannot be controlled due to stroke overshoot, which causes fibers around the wet billet when the wet billet is moved. Splashing outside the cavity of the hot-pressing mold produces a lot of burrs, and the fibers splashed on the hot-pressing mold become coke and pollute the hot-pressing mold because they cannot be removed in time

[0008] 5. The oil cylinder pushes the wet billet transfer mold to crawl when it moves up and down. The movement often shakes and is very unstable. After the seal of the cylinder piston rod is damaged, the hydraulic oil in the cylinder often contaminates the slurry

[0009] 6. The up and down movement speed of the wet billet transfer mold is very slow, and the up and down movement distance of the wet billet transfer die is often very long, which greatly affects the output
