[0002] Ziplock bags (also known as dense bags, bone-attached bags, sealed bags, zipper bags, keel bags) are a type of plastic bag that can be repeatedly sealed, made by blowing polyethylene and high-pressure linear polyethylene, and hot-cutting machine bags. Common materials include PE\PO\EVA, multi-layer composite zipper bags, etc. Before use, it is necessary to test their sealing properties to pick out defective products to ensure the quality of the dense bags;

[0003] After searching, it was found that when the existing device performs the air tightness detection operation, the operator is required to first insert the inflation tube into the interior of the dense bag, and then squeeze and seal the top of the dense bag, and then inflate it to detect its air tightness. The above series of operations need to be performed step by step by the operator, so the operation is cumbersome and the workload is large, which is not conducive to practical application and operation. In view of the above problems, we have introduced a dense bag air tightness detection mechanism. Utility Model Content
