Description
Technical Field
[0001] The utility model relates to the technical field of disposable hygiene product testing devices, in particular to a device for quickly detecting the waist welding strength of pull-ups. Background Art
[0002] In the disposable hygiene product industry, raw materials and technology are innovated relatively fast. In the selection of surface layer and bottom layer materials, ultrafine denier fibers (0.6 - 0.8D) are pursued for very soft touch. The bottom layer material of pull-ups has also been upgraded from spunbond soft, extremely soft, and bicomponent to hot air ultrafine denier fibers. For the hot air bottom layer, when detecting the waist welding strength by ultrasonic or traditional hot pressing, it depends on manual cutting and dividing into three parts: upper, middle, and lower according to regions. The cutting width of each part is 25.4 mm. Test with a laboratory tensile tester. The total time for cutting five standard specimens in a group plus the test time is 30 minutes. For manufacturers that attach importance to quality control, the machine will stop waiting for the test results, resulting in a great waste of production and labor time costs. Some manufacturers adopt the mode of starting the machine while testing. If products with waist burst or cracking due to unqualified waist welding strength flow into the market during the process, it will bring irreversible negative impacts to the manufacturer or brand, such as batch recall of products.
[0003] In order to overcome the above-mentioned objective problems, the utility model provides a device for quickly detecting the waist welding strength of pull-ups. Summary of the Utility Model
