[0020] like Figure 1-4 As shown, the pulp molding device includes a molding frame 1, on which a pulp box 2, an upper template 3, a reducer 4 and a coupling 5 are arranged. The pulp box 2 is connected to a pulp inlet pipe 6, a pulp discharge pipe 7 and a vacuum pipe 8. The reducer 4 is in driving connection with the coupling 5. The coupling 5 is connected to a lifting gear 9. The lifting gear 9 is in driving connection with the upper template 3 through a lifting rack 10. The upper template 3 is located above the pulp box 2. The upper template 3 is connected to an air pressure hose 11 and a vacuum hose 12. It can be understood that the molding frame 1 can be made of stainless steel, etc., and the reducer 4 can be a universal reducer, etc., which can be connected to a servo motor to provide power for the lifting of the upper template 3.

[0021] Specifically, a plurality of hollow guide shafts 13 are installed on the forming machine frame 1, and the hollow guide shafts 13 are connected to the upper mold plate 3. The air pressure hose 11 and the vacuum hose 12 are both connected to the upper mold plate 3 through the hollow guide shafts 13; a slurry inlet valve 14 is installed on the slurry discharge pipe 6, a slurry discharge valve 15 is installed on the slurry discharge pipe 7, and a vacuum valve 16 is installed on the vacuum pipe 8; a mold mounting groove 17 for mounting a mold is provided in the slurry box 2, and the slurry inlet pipe 6, the slurry discharge pipe 7 and the vacuum pipe 8 are all connected to the mold mounting groove 17; a pressure relief valve is installed on the air pressure hose 11, and a vacuum valve is installed on the vacuum hose 12; hot pressing frames 18 are provided on the left and right sides of the forming machine frame 1. It can be understood that the pulp inlet pipe 6 is used to connect the pulp. When the pulp is about 3 cm higher than the mold in the pulp box 2, the pulp inlet valve 14 is closed to stop the pulp inlet. Then, the vacuum valve 16 is opened to suck the pulp through the vacuum pipe 8, so that the pulp residue remains on the mold, and the pulp water is discharged through the pulp discharge pipe, so as to dehydrate the product and form a wet pulp blank on the mold. At this time, the wet pulp blank is formed; then the reducer 4 is started, and the coupling 5 drives the lifting gear 9 and the lifting rack 10, thereby driving the upper template 3 to move downward and The mold is closed, and when closing the mold, the vacuum valve is opened so that the vacuum hose 12 draws vacuum for the upper template to suck the wet pulp blank, and then the reducer 4 is controlled to reversely drive the coupling 5, thereby driving the upper template 3 to move upward, so that the wet pulp blank is separated from the mold, and the wet pulp blank transfer action is completed; subsequently, the hot pressing module on the hot pressing frame 18 can be started to receive the wet pulp blank, and when the pressure relief valve on the air pressure hose 11 is closed, the vacuum valve is closed at the same time, and the upper template 3 loses suction at this time, so that the wet pulp blank can fall on the hot pressing module.

[0022] It can be understood that the utility model has a reasonable design and a unique structure. The pulp box 2 is set to install the mold to form the pulp wet blank, and the pulp inlet pipe 6, the pulp discharge pipe 7 and the vacuum pipe 8 are used to perform grouting, pulp discharge and vacuuming operations respectively. The reducer 4 cooperates with the coupling 5 to drive the upper template 3 to transfer the formed pulp wet blank. It can be used to produce high-quality pulp molding products with high production efficiency.
