A pulp molding processing method in a pulp molding production line, comprising performing the following steps:
- molding paper pulp by a pulp molding machine S, to obtain a pulp wet blank molded product;
- transferring by a pulp molding manipulator 3a, the pulp wet blank molded product, from the molding machine to a press, wherein the pulp molding manipulator 3a having a wet blank transfer mold installed thereon which the wet blank transfer mold being a part of a transfer device Q,
- wherein inside the wet blank transfer mold having an internal airtight air chamber, wherein a front face of the wet blank transfer mold having at least one recessed matching cavity that is configured to be sheathed on an outside of a pulp wet blank container and the at least one recessed matching cavity matches the pulp wet blank container, is recessed towards the airtight air chamber;
- a plurality of small communicating holes are disposed in an inner wall of each recessed matching cavity and at a bottom of the recessed matching cavity for communication between the recessed matching cavity and the airtight air chamber, wherein the plurality of small communicating holes provided in the inner wall of the recessed matching cavity and the small communicating holes provided at the bottom of the recessed matching cavity are circumferentially and uniformly distributed, respectively forming at least one circle in an encircling manner;
- a moving frame parallel to the wet blank transfer mold is connected to a back face of the wet blank transfer mold via a guiding mechanism;
- a driver connected between the back face of the wet blank transfer mold and the moving frame drives the moving frame to move relative to the wet blank transfer mold, and several evenly spaced vacuum cups are provided on the moving frame, wherein the vacuum cups and the airtight air chamber are respectively connected to a vacuum-pumping system;
- wherein the pulp molding manipulator 3a is configured to drive the wet blank transfer mold to approach the pulp wet blank molded product that is held by vacuum suction of the wet blank transfer mold, and to remove the pulp wet blank molded product away from the pulp molding machine S;
- pressing the pulp wet blank paper molded product by a press 2a to obtain a pulp paper product, wherein the press 2a having installed:
- a lower mold and an upper mold which the lower mold is positioned below the upper mold;
- an auxiliary frame N on the press 2a which is driven by a lifting driving mechanism to sleeve on the wet blank transfer mold of the transfer device Q, and force the pulp wet blank molded product which is held by vacuum suction of the wet blank transfer mold for transfer to the lower mold, wherein an auxiliary push plate is sleeved around a main template of the wet blank transfer mold that makes contacts with an annular shoulder;
- wherein a lifting drive mechanism in the press 2a drives the auxiliary push plate to lift or fall in the vertical direction, such that the lower mold moves upwards to approach the upper mold, or the upper mold moves downwards to approach the lower mold to close the mold, so as to press the pulp wet blank molded product to obtain the pulp product, wherein the lower mold and the upper mold withdraw to cancel the mold closing, and the pulp product is configured to be vacuum sucked by the upper mold;
- wherein before the lower mold rises to approach the upper mold, or when the upper mold declines or lowers to approach the lower mold to realize the mold closing, the driver drives the moving frame to move vertically upwards relative to the wet blank transfer mold to force the vacuum cups to suck the pulp product that causes the pulp product to leave the press 2a.
