Description

Paper pulp molding cam pressure device Technical Field The utility model relates to the technical field of pulp molding, in particular to a pulp molding cam pressure device. Background Pulp molding, also known as stereolithography, uses pulp as a raw material and produces a shaped molded product from a special mold on a molding machine. The pulp molding has the advantages of renewable raw materials, convenient transportation, environmental protection and the like, and is mainly used for cutlery boxes, tableware, product trays and the like. The pulp molding product is produced through the steps of beating, compounding, compression molding, hot pressing, etc. In the hot press forming process, hot press forming equipment is generally needed, and the hot press forming equipment on the market at present generally adopts an eccentric wheel structure, so that the hot press forming equipment cannot operate at high speed and can be operated at high pressure simultaneously, the practicability is lower, the energy consumption is higher, and the production efficiency is reduced. Disclosure of utility model The technical problem to be solved by the utility model is to provide the pulp molding cam pressure device aiming at the defects in the prior art, and the pulp molding cam pressure device can work more rapidly, stably and under high pressure by better optimizing the cam curve, so that the production efficiency is improved, the practicability is higher, and the energy consumption is lower. In order to solve the technical problems, the technical scheme of the utility model is as follows: The utility model provides a paper pulp molding cam pressure device, includes the frame, be provided with cam mechanism and last mould lifting unit in the frame, cam mechanism includes cam driving motor and cam, the cam with cam driving motor transmission is connected, go up mould lifting unit and include mould jacking cylinder and last mould, go up the mould with go up mould jacking cylinder transmission and be connected, go up the upper end of mould with the cam offsets, the outside of cam is provided with the cam curved surface, be provided with cam highest point and cam lowest point on the cam curved surface. Preferably, an upper die pressing plate is arranged at the upper end of the upper die, and the upper die pressing plate abuts against the cam curved surface. Preferably, the cam comprises a first cam and a second cam, and the first cam and the second cam are in transmission connection with the cam driving motor through a transmission shaft. Preferably, a hot pressing lower die corresponding to the upper die is arranged on the inner side of the frame, and the hot pressing lower die is located right below the upper die. Preferably, when the highest point of the cam rotates to the lower side, the upper die is pressed downwards, and when the lowest point of the cam rotates to the lower side, the upper die lifting cylinder drives the upper die to lift upwards. Preferably, a plurality of supporting feet are arranged at the bottom of the frame, and the cam driving motor and the upper die lifting cylinder are arranged on the side face of the frame from top to bottom. By adopting the technical scheme, the pulp molding cam pressure device has the beneficial effects that the cam mechanism and the upper die lifting assembly are arranged on the rack in the pulp molding cam pressure device, the cam in the cam mechanism bag is in transmission connection with the cam driving motor, the upper die in the upper die lifting assembly is in transmission connection with the upper die lifting cylinder, the upper end of the upper die is abutted against the cam, the cam curved surface is arranged on the outer side of the cam, and the highest point and the lowest point of the cam are arranged on the cam curved surface.
