Problems solved by technology

[0002] For the paper-plastic molding equipment currently on the market, see the attached figure 1 As shown, it includes a slurry suction die, an extrusion die, a hot pressing upper die, a hot pressing lower die, a transfer die and a discharge fixture, and the hot pressing upper die and the hot pressing lower die will carry out the wet embryo after the upper extrusion in this step Hot pressing is used to set the shape and remove moisture, but because the current technology is to set the suction structure on the lower die of hot pressing, three moving process stations of the lower plate are used, especially the process time of the second link of the station is the longest , how to improve the molding cycle time through reasonable improvement and optimization of equipment is the key

Embodiment 1

[0031] A kind of paper-plastic molding equipment of this embodiment, see figure 2 As shown, the sequence of preparation of pulp molded products includes: slurry suction mold 2, which forms a wet embryo after sucking slurry from pulp pool 1; extrusion mold 3 is arranged on the corresponding top of slurry suction mold 2, and After the pulp mold 2 is reversed upwards with the wet embryo, the wet embryo is first extruded with the extrusion mold 3; the hot pressing upper die 4 can move up and down in the vertical direction; the hot pressing lower die 5 can move left and right in the horizontal direction, when When moving to correspond up and down with the hot-pressing lower die 5, the wet embryo is subjected to hot-pressing treatment; the hot-pressing upper die 4 is provided with an air suction structure, and the hot-pressing lower die 5 is provided with an air-blowing structure; the hot-pressing lower die 5 and The transfer die 8 placed on the downstream side of the hot pressing ...

Embodiment 2

[0035] This embodiment provides a molding method of pulp molding, see Figure 5 shown, including the following steps:

[0036] After the pulp suction die 2 sucks the pulp from the pulp tank 1, it turns over, squeezes with the extrusion die 3 on it, and turns over again after extrusion. At this time, the hot pressing lower die 5 moves to the left to the pulp suction die 2 Below, the slurry suction mold 2 places the wet embryo in the hot-pressing lower mold 5, at this time, forming station 1, the hot-pressing lower mold 5 moves to the right to the position corresponding to the hot-pressing upper mold 4, forming a station Two, at this time, the hot-pressing upper die 4 moves vertically downward, extrudes the wet embryo with the hot-pressing lower die 5 and heats it to shape. There is a blowing structure, therefore, the molded product formed here is on the hot-pressing upper mold 4, and then the hot-pressing lower mold 5 and the transfer mold move to the left together, and return...

Abstract

The invention discloses a molding equipment for pulp molding. According to the sequence of preparation of pulp molding products, it comprises: a slurry suction mold absorbs slurry from a pulp pool to form a wet embryo; an extrusion mold is arranged above the slurry suction mold, and After the slurry mold is reversed upwards with the wet embryo, it will be squeezed with the extrusion mold for the first time; the hot pressing upper mold can move up and down in the vertical direction; the hot pressing lower mold can move horizontally left and right. When the pressing mold is up and down, the wet embryo is hot-pressed; the hot-pressing upper mold is provided with an air suction structure, and the hot-pressing lower mold is provided with an air-blowing structure; the invention also discloses a pulp molding method , including slurry suction, extrusion, hot pressing, transfer, after the heating is completed, when the hot pressing upper mold and the hot pressing lower mold are separated, the formed molded product is absorbed and transferred by the hot pressing upper mold. The above-mentioned equipment and method reduce the equipment molding movement time and improve the cycle period for equipment to prepare molded products.

Description

technical field [0001] The invention relates to the technical field of molding preparation, in particular to a molding equipment and method for pulp molding. Background technique [0002] For the paper-plastic molding equipment currently on the market, see the appendix figure 1 As shown, it includes a slurry suction die, an extrusion die, a hot pressing upper die, a hot pressing lower die, a transfer die and a discharge fixture, and the hot pressing upper die and the hot pressing lower die will carry out the wet embryo after the upper extrusion in this step Hot pressing is used to set the shape and remove moisture, but because the current technology is to set the suction structure on the lower die of hot pressing, three moving process stations of the lower plate are used, especially the process time of the second link of the station is the longest , how to increase the molding cycle time through reasonable improvement and optimization of equipment is the key.
