Packaging box equipment

Abstract

The invention belongs to the technical field of packaging boxes, and particularly relates to packaging box equipment. The packaging box equipment comprises a top cover, an outer box body, a reaction module and a storage box body. In the using process of a packaging box, firstly, freezing treatment needs to be carried out on a freezing shell, when the freezing treatment is carried out on the freezing shell designed by the invention, a frozen medium in four freezing blocks flows back into the freezing shell, and then the four freezing blocks are pressed into a ball to be placed on the freezing shell, so that the space, occupied by the freezing shell during freezing, of a refrigerator is reduced, and freezing of the freezing shell is facilitated; and meanwhile, according to the designed reaction module, in the process of refrigerating articles in the storage box body, after the frozen medium in the freezing shell and the freezing blocks absorbs heat to be melted, the reaction module is triggered through the change of the volume of the frozen medium, substances, located at two sides of a partition plate, in a shell of the reaction module are in contact to generate chemical reaction, and the frozen medium in the freezing shell and the freezing blocks absorbs heat to be frozen again, so that the refrigeration time of the packaging box is prolonged.

Description

[0001] Technical field [0002] The invention belongs to the technical field of packing boxes, and in particular relates to packing box equipment. Background technique [0003] With the rapid development of the express delivery industry, when transporting express items that need to be refrigerated, the outside of the express items is usually wrapped with a layer of ice cubes, and then the outside of the ice cubes is wrapped with foam to keep them warm. The block will gradually melt over time, and the cold storage of the express items will fail, causing the express items to be damaged by heat, and the cold storage time is short. The design is suitable for the express industry, and a cooler with a longer cold storage time is necessary. . [0004] The present invention designs a packing box equipment to solve the above problems. Contents of the invention [0005] In order to solve the above-mentioned defects in the prior art, the present invention discloses a packaging box eq...
