Description

Technical Field

[0001] The utility model relates to an improvement of a packaging mechanism, in particular to an improvement of an inner support mechanism of a retractable and retractable roll packaging. Background Art

[0002] Most thin products are rolled on rolls during packaging, storage and transportation. For example, fabrics, fabrics, paper products and other finished products or intermediate products are rolled before storage and transportation, which is convenient for packaging, storage and transportation. Figure 1 There are many problems with these thin products A during the winding and unwinding process. The tightness of these thin products during winding and unwinding will affect the winding and unwinding process. For example, the tightness of the product on the inner support mechanism B during winding will affect the degree of winding. When the inner support mechanism B is too loose, the product and the inner support mechanism will slip, which will make it impossible to wind; and the inner support mechanism B and product A are too tight, which will make it difficult to push out the product. At the same time, the thin product A will change its tightness due to changes in temperature, humidity, and storage scenarios, which will affect the packaging and storage and transportation of the product. In particular, when the outer diameter of an inner support mechanism cannot change, it is easy to slip during the winding process. Utility Model Content
