Insulation bag processing process and insulation bag processed through process

Abstract

The invention relates to an insulation bag processing process and an insulation bag processed through the process. The process includes the steps of cutting a raw material into all parts of the insulation bag, welding an external bag zipper and an internal bag zipper to the long side of an external bag large body face cut part and the long side of an internal bag large body face cut part correspondingly, welding the two short sides of the external bag large body face cut part together, welding a back carrying unit to the back side of an outer frame, welding the two short sides of the internalbag large body face cut part together, welding a lining bottom cut part to the bottom of an inner frame, welding a lining mouth cut part to the bottom side of the internal bag zipper on the top of aninner bucket body, seamlessly welding an inner bucket structure to an outer bucket structure so that an insulation layer can be clamped in a sealed cavity formed between the inner bucket structure andthe outer bucket structure, and welding a bag cover cut part to the external bag zipper on the outer bucket structure to form a complete bag body. The insulation bag is high in airtightness, and theinsulation effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of heat preservation bags, in particular, to a heat preservation bag processing technology and a heat preservation bag processed therefrom. Background technique [0002] Insulation bag, a kind of outdoor luggage, is a bag used to hold various foods and keep food temperature and freshness. It can also be used for refrigeration, such as ice cubes, cold drinks and other low-temperature items, so it can be kept Heat preservation and cold preservation are the most basic functions of thermal insulation bags. [0003] During the processing of the thermal insulation bag, the raw materials need to be cut into various parts of the thermal insulation bag, and then the parts are melted and spliced ​​to obtain a complete thermal insulation bag. Existing splicing methods of heat preservation bags are mainly manual sewing or sewing by sewing machines, and the heat preservation bags obtained by sewing will inevitably produ...

AI Technical Summary

Problems solved by technology

The existing splicing methods of thermal insulation bags are mainly manual sewing or sewing by sewing machines. The thermal insulation bag obtained by sewing will inevitably produce gaps at the seams, which will affect the overall appearance of the thermal insulation bag

At the same time, such gaps and seam traces make the seams not well sealed, reducing the sealing performance and quality of the thermal insulation bag

In order to improve the thermal insulation performance of the thermal insulation bag, the high-frequency welding process can be used instead of machine stitching for some gaps that are easy to crack. However, the high-frequency welding process has high technical requirements for operators, and the process parameters need to be adjusted for welding of different materials. The overall processing cost High, difficult to promote on a large scale
