Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification of packaging bags, in particular to a dehumidification packaging bag. Background Art

[0002] Objects stored in packaging bags need to be kept dry. The current common method is to add a dehumidifier bag in the bag. However, this method has disadvantages. For example, during the vibration of the packaging bag during transportation, the dehumidifier bag is easily shaken into a corner, which makes it easy for the radiation range of the dehumidifier bag's moisture absorption function to not cover all objects in the bag.

[0003] For example, the existing patent 202222375402.2 discloses a packaging bag with a dehumidification function, which will not affect the normal use of the desiccant by setting a breathable mesh plate, and can dry the material in the bag body. The vertical plates and horizontal plates are placed inside the material, and multiple groups of horizontal plates are provided, so that the desiccant can fully dry the material and improve the problem of insufficient local drying of the material. However, since most of the existing packaging bags are made of soft plastic, it is difficult to add structure inside them. Some other manufacturers will fix the dehumidification bag on the inside of the bag body. Although this method fixes the position of the dehumidification bag, it is difficult for the dehumidification bag to radiate the bag body to the other side. Therefore, this method may consume multiple dehumidification bags.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0008] Preferably, the unfolding assembly includes a threaded sleeve 1 and a threaded sleeve 2 symmetrically arranged on the screw rod, and a rotating shaft is provided on both sides of the threaded sleeve 1 and the threaded sleeve 2. One end of the two groups of rotating shafts is provided with an inclined movable rod, and one end of the movable rod is provided with a connecting piece connected to the dehumidification bag.
