Description

Technical Field

[0001] The utility model relates to the technical field of paper tray production, in particular to a paper pulp tray shaping device. Background Art

[0002] Paper trays are made of waste paper and are made through processes such as pulping, vacuum adsorption molding, and drying. They are environmentally friendly and recyclable products that do not pollute the environment. Traditional pulp molding is to allow the pulp to dry and shape naturally in the mold. This method has a long molding cycle, relatively low efficiency, and it is difficult to guarantee product accuracy.

[0003] Therefore, stamping forming is now mostly used. It only requires placing the dry pulp film in a stamping mold, and then using a stamping machine to quickly stamp the dried pulp film, so that the pulp film can be quickly shaped in the mold, greatly improving production efficiency and product quality stability, and improving product qualification rate.

[0004] When the punching machine is used to quickly punch the dried pulp film, the dried pulp film needs to be cut and trimmed according to the required size and shape, so as to ensure that the cut film size is accurate and the edge is flat. The current paper tray shaping device generally has a structure as described in a shaping device for paper tray production disclosed in patent application number "CN202223291034.X", including a working platform, a paper tray forming unit is fixedly connected to the outer surface of one side of the working platform, a buffer cavity is opened on the upper surface of one end of the working platform, and a discharge unit is arranged on the inner surface of the buffer cavity, and the discharge unit is arranged at a corresponding position directly below the paper tray forming unit; the paper tray forming unit includes a support mechanism and an energy-saving installation mechanism, and the inner side surface of the lower end of the support mechanism is fixedly connected to the outer surface of the working platform. However, before punching the pulp film, this utility model needs to uniformly cut the pulp film in advance and load it in sequence, thereby increasing the production cycle, reducing the production speed of the pulp tray, and the efficiency is relatively low.
