Description

Hair blowing conveying system and conveying method thereof

Technical field

The invention relates to a conveying system, in particular to a blowing conveying system for conveying a buffer air bag and a conveying method thereof.

Background technique

In the e-commerce packaging industry, the airbags made by the cushion air cushion machine are used to package the online shopping products to prevent the goods from being impacted during transportation. Usually, the e-commerce company will simultaneously package the online shopping products on a relatively long packaging line. It is necessary to store a plurality of air bags in a plurality of air bag storage boxes to correspond to a plurality of packaging positions, that is, a plurality of cushioning air cushion machines may be required to make air bags to meet packaging requirements, or the e-commerce chamber is equipped with a long storage box for multiple packages. The position of the air bag is used. When the storage box is long, the existing air bag conveying pipeline cannot satisfy the filling of the air bag in the storage box by a single cushion air cushion machine, and the gas bag cannot be filled up at a position far from the cushion air cushion machine. Bags, e-commerce can only be equipped with a buffer air cushion machine and conveying pipeline at different positions of a long storage box to make bags and fill the storage box, thus increasing the cost of the electric commercial bag packaging.

Summary of the invention

It is an object of the present invention to provide a hair dryer delivery system and a delivery method thereof to solve at least one of the above technical problems.
