[0055] Another technical problem to be solved by the present invention is to provide a forming method of a forming device based on a pulp recycling lunch box, comprising the following steps:

[0056] S1. Accessories selection

[0057] A forming mold 32 that matches the shape of the tableware to be produced can be pre-installed inside the frame plate 31, and two forming molds 32 can be installed inside the frame plate 31 at one time, which can be flexibly switched during production. At the same time, the male mold body 42 and the female mold body 41 can be selected and installed.

[0058] S2, wet embryo molding

[0059] The slurry required for molding is injected into the slurry pool 1, and the molding die 32 to be used is turned to an upward position. After it is controlled to be immersed in the slurry pool, the pulp fibers form a semi-wet wet embryo product in the molding die 32 and are suspended above the slurry for drainage;

[0060] S3, wet embryo transfer

[0061] The wet embryo product after draining in step S2 is vacuum-adsorbed and then transferred to the die body 41 for transportation;

[0062] S4, hot pressing

[0063] The male mold body 42 is controlled to move downward and press into the female mold body 41, thereby performing hot pressing molding on the wet embryo product to complete the molding manufacturing process.

[0064] In actual operation, when the device is used, first the device is connected to the power supply, and the prepared slurry is first injected into the slurry pool 1. Two forming dies 32 can be installed inside the frame plate 31 at one time. When installing, different forming dies 32 are directly placed from the top and bottom of the frame plate 31 respectively until the mounting plate 33 extends into the inner side of the L-shaped plate 34 and fits with it. Then, the bolts are screwed in to complete the installation and fixation. Accordingly, the installation process is simple and convenient.

[0065] When the second positioning plate 46 is passed through the rectangular plate 45, the first positioning plate 43 is limited and cannot be moved, and the installation of the male mold body 42 is completed.

[0066] During specific production, after the motor 398 works, it drives the bidirectional threaded rod 395 to rotate. When the bidirectional threaded rod 395 drives the two long plates 396 to move away from each other, the long plate 396 drives the first push-pull plate 397 to flip, and the bottom plate 35 can only slide vertically up and down in the slurry pool 1. Then, after the first push-pull plate 397 flips, it pulls the bottom plate 35 downward. According to the above connection relationship, it can be seen that at this time, the forming mold enters the slurry, and the pulp fibers are adsorbed in the forming mold 32 to form a semi-wet wet embryo product. Subsequently, the two long plates 396 are controlled to move toward each other, which is the opposite of the above operation. At this time, the forming mold 32 rises to a height higher than the slurry and then drains. The drained water is discharged to the outside through the drain port 382.

[0067] After the water is fully drained, the fifth electric push rod 56 pushes the vacuum suction cup body 51 downward, causing the vacuum suction cup body 51 to move downward and absorb the wet embryo product. Then, the vacuum suction cup is controlled to rise and move to the top of the die body 41 by rotating the electric roller 54. After the wet embryo product is placed into the interior of the die body 41, the vacuum suction cup body 51 is controlled to move to one side of the die body 41. The fourth electric push rod 496 pushes the rectangular plate 45 downward. The rectangular plate 45 drives the punch body 42 to move downward until it enters the interior of the die body 41, and then the hot pressing operation is performed. When the hot pressing is completed, the formed tableware product can be obtained.

[0068] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
