When the pulp sucking mould leaves the pulp pool, the pulp sucking and dehydrating actions are realized through the vacuum valve, and when the pulp sucking and dehydrating actions are finished, the pulp sucking mould ascends, and at the moment, the vacuum valve does not perform opening and closing actions. When the transfer mould is folded towards the pulp suction mould to transfer the product, the left mould and the right mould are opened for vacuum adsorption, and the pulp suction mould is opened for blowing air, so that the handover is realized.
