Description

Technical Field

[0001] The utility model relates to the technical field of biological ice bags, in particular to a non-woven fabric biological ice bag roll film composite structure. Background Art

[0002] Biological ice packs belong to the category of ice packs. They use CMC, a new type of material with large cold capacity, to keep biological agents, blood, fruits, etc. that need to be transported at low temperatures warm. Biological ice packs actually have nothing to do with biology. Biological ice packs are a biological product used to refrigerate items and keep them in a low temperature state. In view of the many difficulties such as the prohibition of the use of dry ice in aviation, the use of dry ice is necessary, the dry ice cannot be reused, the high cost of use, and the difficulty in purchasing dry ice in remote areas, the ultra-low temperature dry ice type technology ice packs with a temperature range of -190°C are introduced. The preparation of biological ice packs needs to go through the process of film roll lamination. The hot pressing lamination mechanism is a device that guides two or more layers of the same or different materials, such as non-woven fabrics and filter membranes, non-woven fabrics and paper, and various plastics, rubber sheets and rolls, etc., to a melted or semi-melted state.

[0003] The utility model with publication number CN214266714U discloses a thin film hot pressing composite mechanism, including a supporting device and a hot pressing device, wherein the supporting device is used to support the hot pressing device, and the hot pressing device is used to hot press materials, and the hot pressing device includes a plurality of hot pressing components, a heating component and a driving component, and the plurality of hot pressing components are distributed up and down, and the hot pressing component includes a hot pressing roller and a mounting seat, and the hot pressing roller is connected to the mounting seat, and the driving component can drive the hot pressing roller to rotate, and the heating component includes an oil transport layer and an oil inlet pipe, and the oil transport layer is located between the mounting seat and the hot pressing roller, and the oil inlet pipe is connected to the oil transport layer.
