Recyclable paper packaging box based on paper polypropylene

Abstract

The invention relates to the technical field of paper product making, and discloses a recyclable paper packaging box based on paper polypropylene. The packaging box comprises a box body. A box cover is arranged above the box body, an insertion rod is fixedly connected to the bottom of the box cover, a carrying plate is arranged below the insertion rod, and an extrusion toothed rod is fixedly connected to the bottom of the carrying plate. A transition wheel is connected to the side face of the extrusion toothed rod in an engagement mode, a pull rod is connected to the side face of the transition wheel in an engagement mode, a heating block is arranged below a pressure sensing switch, a heat conduction rod is fixedly connected to the bottom of the heating block, a mercury box is arranged below the heat conduction rod, and a mercury plate is connected to the interior of the mercury box in a sliding mode. According to the recyclable paper packaging box based on the paper polypropylene, because the carrying plate and the heating block are used in cooperation, the effects that the humidity of the packaging box can be automatically reduced, the packaging box is prevented from being softened and damaged, and the packaging box can be recycled are achieved.

Description

technical field [0001] The invention relates to the technical field of paper product manufacturing, in particular to a recyclable paper packaging box based on paper polypropylene. Background technique [0002] Paper product manufacturing refers to the production activities of using paper and cardboard as raw materials and further processing them into paper products. It has the advantages of high cost performance, good elasticity and toughness. After nearly 30 years of development, China's paper product packaging industry has now gone By the middle stage of industrialization, the rudiments of large-scale and intensive development have been formed. The existing paper polypropylene new material, this new paper-based material, is strong, tough and environmentally friendly, and can reasonably replace those that should have Use paper-based plastic. [0003] There is a paper product packaging box made of the above-mentioned new paper material. During use, due to the water absorpti...
