Secondary forming processing machine for polyurethane plastic foam packaging material

Abstract

The invention relates to a secondary forming processing machine for a polyurethane plastic foam packaging material. The secondary forming processing machine comprises a workbench, clamping centering mechanisms, a cutting lifting mechanism and an adjustable cutting mechanism, wherein circular holes are formed in the workbench; the four clamping centering mechanisms for clamping circular disc-shapedpolyurethane plastic foam in a matched mode are arranged at the positions, located around the circular holes, of the workbench in a distributed mode, and the four clamping centering mechanisms are evenly distributed in an annular array mode relative to the centers of the circular holes; and the cutting lifting mechanism is arranged on the workbench, and the adjustable cutting mechanism is arranged on the cutting lifting mechanism and ascends and descends along with the cutting lifting mechanism. The machine can complete forming processing of the four circular holes in a foam packaging structure at a time, solves the problems of low one-by-one processing efficiency, uneven circular hole distribution and the like, and in addition, can carry out forming processing on foam packaging structures with different size structures, so that the applicability of the machine is improved.

Description

technical field [0001] The invention relates to the technical field of foam packaging material processing, and specifically proposes a secondary molding processing machine for polyurethane plastic foam packaging materials. Background technique [0002] Polyurethane plastic foam can be divided into rigid polyurethane plastic foam and soft polyurethane plastic foam. Among them, rigid polyurethane plastic foam is made of isocyanate and polyether as the main raw materials. Under the action, it is a high-molecular polymer that is mixed by special equipment and foamed on-site by high-pressure spraying. The rigid polyurethane plastic foam has a closed-cell foam structure. Rigid polyurethane plastic foam is also often used in the field of packaging, for product fixing, anti-collision protection, etc. [0003] When rigid polyurethane plastic foam is used in the packaging field, the foam board is often further processed through secondary processing to obtain the required foam packagi...

Problems solved by technology

[0003] When rigid polyurethane plastic foam is used in the packaging field, the foam board is often further processed through secondary processing to obtain the required foam packaging structure. Figure 7 Among them is a kind of foam packaging structure with the characteristics of the drawing obtained through the secondary molding processing of a polyurethane plastic foam packaging material provided by the present invention, specifically a disc-shaped foam board, and on the foam board There are four circular holes processed in the central ring array, which are used to fasten and fix the four cylindrical products and package them as a whole. In actual processing, it is often necessary to obtain this type of foam packaging structure of different sizes. Therefore, the method of cutting and punching holes one by one is often used in secondary processing. Obviously, there are many problems in this processing method, such as many operation steps, low processing efficiency, and uneven distribution of round holes.
