An explosion-proof gas column roll for logistics packaging and transportation

Abstract

The invention relates to an explosion-proof air column roll used for logistics packaging and transportation. The explosion-proof air column roll used for logistics packaging and transportation comprises an air column roll body, a winding device and a deflation device. The winding device is mounted at the rear end of the air column roll body. The deflation device is mounted at the front end of thewinding device. The air column roll body is located in the deflation device. By adoption of the explosion-proof air column roll used for logistics packaging and transportation, the problems that an existing air column roll needs to be sequentially inflated and deflated manually when needed, and the inflation and deflation process is complex; when wound after being deflated, the existing air columnroller needs to be manually wound by personnel after being pressed to be deflated, and deflation is incomplete; gas in the existing air column roll cannot be completely exhausted from deflation holeswhen the existing air column roll is pressed by the personnel, and consequentially, an explosion of the existing air column roll is caused; and when the existing air column roll is wound manually, the wrinkled air column roll has to be continuously flattened, and consequentially, time consumption is high, the labor intensity is high, and the efficiency is low are solved; and the air column roll body can be inflated conveniently and be deflated and wound automatically.

Description

technical field [0001] The invention relates to the technical field of logistics packaging, in particular to an explosion-proof gas column roll for logistics packaging and transportation. Background technique [0002] The modern logistics industry is developing rapidly. The protection of logistics packaging products is an important service in the logistics industry. Cushion packaging is commonly used in protective packaging. The products studied in cushion packaging are mainly to prevent the packaging from breaking during logistics transportation, mainly electronic and electrical products. In cushioning packaging technology, air column membrane is a new packaging system filled with natural air. The main purpose of the air column coil is the packaging and transportation of products. Its main function is to cushion and protect the packaged items. The air column coil is filled with air to form a protective layer with a certain thickness and support strength. When used, it can b...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides an explosion-proof air column roll for logistics packaging and transportation, which can solve the problem that the existing air column roll needs to be manually inflated and deflated sequentially when filling and deflated, which is cumbersome. Personnel usually press and deflate the existing air column roll and then manually rewind the roll. The deflation is not complete, and the gas in the existing air column roll cannot be completely discharged from the vent hole when the person presses, causing the existing air column roll to burst. When winding, the wrinkled air column needs to be flattened continuously. The process takes a long time, labor intensity is high and the efficiency is low. It can realize the functions of convenient inflation of the air column body and automatic exhaust winding, which is convenient. Inflate, automatically deflate the air column roll body, control the deflation speed, and there will be no bursting, automatically tighten the air column roll body, and automatically flatten the air column roll body, which takes a short time and has simple operation and labor intensity Small size and high work efficiency
