Description

A device for making recyclable adaptive express packaging and its use method

Technical field

The invention relates to the technical field of packaging and logistics, and in particular to a device for making recyclable adaptive express packaging and a method of using the same.

Background technique

With the rapid development of the express logistics industry in modern society, the amount of cargo packaging is getting larger and larger, and the requirements are getting higher and higher. However, the existing express packaging methods still follow the more traditional methods, and there are many problems: The most common express delivery The packaging method is to use corrugated cartons for packaging. For mass-produced goods, they can be filled and fixed with plastic foam corresponding to their shape. The shockproof and anti-fall effects are better, but for scattered goods, they can often only be packaged in corrugated cartons. Some waste paper or inflatable bags are manually filled in to fix it. Due to the limited specifications of the corrugated cartons and the various shapes of the goods, manual temporary filling is often ineffective, resulting in weak compression and fall resistance of the packaging, making it easy to damage. The goods cause damage, especially to fragile items such as glass and ceramics, and many express companies even refuse to transport them, causing great inconvenience to people's lives. At the same time, due to the poor matching between the shape of the carton and the goods, most existing express packaging is completed manually, making it difficult to achieve automated and mechanized operations, resulting in low express packaging efficiency and hindering the automated development of the express packaging industry. In addition, the existing express packaging methods do not provide portable parts, which makes it difficult for people to twist or lift when picking up the express delivery, making it inconvenient to carry.

In order to solve the above problems, many technologies have emerged. For example, CN210761841U discloses a fragile express packaging component, including an inner packaging film, an instant foam fixing piece and an outer packaging box. The inner packaging film can realize special-shaped fragile interior items. Isolated from the environment, instant foam fasteners fix the reasonable stress-bearing parts of a single piece of special-shaped fragile interior items. The outer packaging box has a split structure, including at least four orifice plates. The orifice plates (a flat plate structure with holes, between each other) The detachable connection surrounds the contents, and a lead seal is used to avoid illegal unpacking. The detachable connection and the instant expansion of the foaming fasteners complete the packaging process. This invention uses a foaming agent as a buffering fastener inside the outer packaging box, but still The outer packaging box is retained as a fixed support for packaging, which is suitable for on-site packaging and is not conducive to mechanization and automation. The structure of the outer packaging box is relatively complex, the cost is high, and the operation is difficult.

For example, CN210761841U discloses a circulating express box with a buffering function and an adjustable volume, an active box, a bottom box, a position adjustment device and a buffer telescopic device. The active box includes an active box body, a lid, hinges, convex edges and Velcro. , the bottom box includes the bottom box body, slide rails and bottom airbags. The position adjustment device includes buckles, boss limit structures and torsion springs. The buffering and telescopic device includes upper cover airbags, air guide tubes, retractable airbags, airbag boxes, Air bag coil spring, rotating support plate and ruler hook; this invention designs the outer shell of the express box to be adjustable, and uses an air bag as a buffer device inside, realizing the recycling of express packaging, but it still does not get rid of the basic structural model of traditional express packaging. The shell design is complex and costly, which is not conducive to automated and mechanized operations.

For example, CN106144231A discloses a fragile express delivery filled with paraffin foam particles, including a heating device, a packaging room for placing packaging cartons, and a paraffin foam particle storage bin for storing paraffin foam particles. The paraffin foam particle storage bin and packaging The chamber is connected through a pipe for introducing paraffin foam particles into the packaging carton. The packaging carton is provided with an inlet and a corresponding connection to the pipe. A vent is provided on one side of the packaging chamber to communicate with the heating device. The invention uses paraffin foam particles as The filling material needs to be heated to 70°C and above to complete the shaping. It is not suitable for temperature-sensitive cargo packaging, and it still does not get rid of the basic structural model of traditional express packaging.
