Servo-motor-driven dual-hot-pressing plant fiber molding method and machine

Abstract

The invention relates to a method and device to manufacture plant fiber products containing pulp by means of molding and is intended to provide a full-automatic manufacture method and device of plantfiber molded products, which have good operation stability and higher yield. According to the technical scheme, a servo-motor-driven dual-hot-pressing plant fiber molding method comprises the steps of1) allowing a suction filter forming device to manufacture a wet blank with slurry and transfer the wet blank to a left hot-pressing lower mold 3c or right hot-pressing lower mold 4c of a wet blank transfer station 7.1; 2) allowing the wet blank transfer station 7.1 to receive the wet blank to the left hot-pressing lower mold, and carrying the wet blank to horizontally move along a hot-pressing lower mold horizontal rail 8 to a left hot-pressing station 3.1; allowing a left hot-pressing upper mold 3a to move down and to be closed, and performing hot-pressing and drying on the wet blank to shape; 3) allowing the left hot-pressing upper mold 3a to move up and separate from the left hot-pressing lower mold, and taking out a dried product; allowing a right hot-pressing upper mold 4a to move up and separate from the right hot-pressing lower mold, and taking out the dried product.

Description

technical field [0001] The present invention relates to a method and device for making plant fiber (abbreviated as plant fiber; hereinafter the same) products including pulp by molding; it is suitable for making disposable planar or non-planar plant fiber molded products, especially suitable for making one-time Non-planar paper products; such as plant fiber tableware, plant fiber trays, plant fiber industrial products shockproof pads and packaging trays or boxes, disposable non-planar plant fiber decorative three-dimensional wall panels (or plant fiber three-dimensional wallpaper or pulp molded three-dimensional wallpaper), delicate small-angle plant fiber industrial packaging trays and box products, and all disposable plant fiber molded products, hereinafter collectively referred to as plant fiber molded products. Background technique [0002] The existing fully automatic plant fiber molding machine with double hot-pressing setting mode includes an upper frame, a lower fram...

AI Technical Summary

Problems solved by technology

[0004] 1. The up and down movement of the wet billet transfer mold, the horizontal movement of the left hot pressing lower mold, the horizontal movement of the right hot pressing lower mold, the up and down movement of the left hot pressing upper mold, and the up and down movement of the right hot pressing upper mold are all driven by oil cylinders , is driven by an oil pump. For the stability of the movement, all the oil cylinders move separately and sequentially. Two or more oil cylinders cannot overlap in movement time, which will undoubtedly increase the operating cycle and affect the output.

[0005] 2. Use the oil cylinder to push the hot-pressing lower die mounting plate to move back and forth along the track between the suction filter forming device and the hot-pressing shaping device. If the horizontal movement speed is too fast, it will cause the hot-pressing lower die mounting plate to reach the suction filter forming device. There will be an impact at the two positions of the hot-press setting device, and if the horizontal movement speed slows down, it will affect the output

[0006] 3. The hot-pressing lower die mounting plate used to fix the hot-pressing lower die can be positioned horizontally on the horizontal track of the hot-pressing lower die through the slider, so when the hot-pressing die is closed, the slider and the hot-pressing lower die’s horizontal track It needs to bear a lot of clamping force, the horizontal track of the hot-pressing lower die is easy to be deformed by force, it is difficult to ensure the parallelism between the hot-pressing upper die and the hot-pressing lower die, and the service life of the slider and the track is greatly shortened

[0007] 4. The mounting plate of the hot-pressing lower die is completely supported by the sliders on the two horizontal rails on the front and rear sides. The span is relatively large. If there is a concave surface, the hot pressing die will be deformed, which will seriously affect the quality of the product
