An automatic forming machine for pulp molding product is disclosed. Through an innovative design to ensure stable rise and fall of the hot pressing lower mold, the hot forming zone is optimized. The invention has the following characteristics: On the bottom side of the hot pressing lower mold, a supporting arm is extended downward in each of the four directions. On the supporting arm, a sliding block is fixed. A penetrating hole slot is configured on a base plate at a lower position inside the working space of the hot forming zone at each of the positions corresponding to the supporting arms. The adjacent outer sides of the base plate corresponding to the supporting arms are respectively fixed with a supporting frame. The column surfaces of the supporting frame on the front and rear side are respectively connected with a supporting plate body. The supporting plate body is fixed with a guide rail. The sliding block on the supporting arm is sleeved on the guide rail, so that when the hot pressing lower mold rises or falls, the sliding block can rise or fall simultaneously along the guide rail, maintaining balanced rise and fall of the hot pressing lower mold. Thus, the hot pressing lower mold and the hot pressing upper mold can clamp correctly to enhance product quality.

Provided are a production process for a rotating hub type paper-plastic product, and a device utilizing the production process. The device comprises: a rotating hub forming unit, which can continuously generate a primary blank; an array unit, which forms, by means of an uplink lifting mechanism, a downlink descending mechanism, an uplink array channel and a downlink array channel, a carrier capable of moving in a circulating and reciprocating manner for a profiling jig plate moving in a reciprocating manner thereon; a left forming area unit and a right forming area unit which are respectively arranged at two sides of the array unit and are internally provided with machining areas for a plurality of hot-pressing shaping mechanisms and a plurality of edge cutting mechanisms for use in hot-pressing shaping and edge cutting of the primary blank; a first transfer mechanism and a second transfer mechanism which stretch across the array unit and the left and right forming area units and are provided with a plurality of conveying molds in a suspended manner, so that the primary blank can be transferred; two discharging conveyors which are respectively arranged on the outermost sides of the left and right forming area units; and two defective product conveyors which are arranged between each of the left and right forming area units and each of the discharging conveyors for outputting a defective product which is subjected to screening.
