Abstract
A paper pulp molding device has a reversing demolding mechanism and a vacuum set. The reversing demolding mechanism has a transmission set and at least one suction set. The at least one suction set is rotatable and driven by the transmission set. Each one of the at least one suction set has multiple sucking structures. Each sucking structure has a hollow unit and a vacuum suction disc communicating with the hollow unit. The vacuum set has a vacuum apparatus and multiple hoses. Each hose respectively communicates with the hollow unit of one of the sucking structures and the vacuum apparatus. The vacuum suction disc of each sucking structure enlarges the contact area between the vacuum suction disc and a container to reinforce the suction force produced by the vacuum apparatus.
