  • Publication number: 20240018727
    Abstract: An automatic forming machine for a pulp molding product and a manufacturing method therefor. During manufacturing, a slurry suction mold immersed in a slurry box suctions a slurry to form a slurry layer, and then ascends to leave the slurry box to assemble with an upper hot pressing mold, which moves in from an external space, for extrusion to form a preform; then the slurry suction mold descends into the slurry box for a second round of slurry suction; the upper hot pressing mold suctions the preform and returns in a reverse direction to an original position; then a lower hot pressing mold ascends for assembling to hot press and shape the preform to form a pulp molding product, and the lower hot pressing mold suctions the pulp molding product and descends to the original position; and a material receiving mechanism then suctions the pulp molding product and leaves the lower hot pressing mold for separate collection.
