Foam plastic packaging box convenient for low-temperature storage

Abstract

The invention belongs to the technical field of packaging equipment, in particular to a foam plastic packaging box convenient for low-temperature storage. The foam plastic packaging box comprises an inner box body, an inner box cover, an outer foam plastic box body, an outer foam plastic box cover, sealing modules, clamping modules and storage modules; the two sealing modules are arranged at the two sides of a top opening of the inner box body; the storage module is arranged on the inner side, between the two sealing modules, of the inner box body; support modules are arranged on a bottom plate on the inner side of the inner box body; the storage modules are symmetrically arranged about the vertical midline of the inner box body; each storage module comprises a rectangular air bag and a partition plate; first air passages are formed in the partition plates; the support modules are arranged between the two storage modules; the two clamping modules are arranged at the parts, positioned on the outer sides of two air cylinders, of the inner side of the inner box cover; each clamping module comprises an L-shaped guide rod and a telescopic airbag; and second air passages are formed in the L-shaped guide rods. Multiple sealing is carried out through the cooperative use of the sealing modules, the storage modules and the clamping modules, and the sealing efficiency of the foam plasticpackaging box is improved.

Description

technical field [0001] The invention belongs to the technical field of packaging equipment, in particular to a foam plastic packaging box which is convenient for low-temperature storage. Background technique [0002] Now more and more people like to travel, and they will bring a lot of food when they go out, especially some iced drinks, which are usually stored in foam plastic packaging boxes, but the existing small refrigerated packaging boxes are all used. It is a foam material, which is light in weight, cheap, and has a good sealing effect, so it is widely used. However, most of the existing refrigerators are stored by directly placing the ice bag in the packaging box and directly contacting the food. The sealing effect is not good, it is easy to cause cold air leakage, and reduce the effect of cold storage of food. [0003] There are also some technical solutions for packaging equipment in the prior art. For example, a Chinese patent with application number 201710200256...

Problems solved by technology

However, when this kind of packaging equipment seals the packaging box, it only adopts a way of closing the lid. However, when there is a gap in the lid, the refrigeration effect of the packaging box will be reduced, causing losses. Therefore, a Styrofoam packaging box for low temperature storage, capable of multiple sealing of the packaging box, thereby enhancing the sealing effect of the packaging box
