A device for detecting water absorption of sanitary napkins

Abstract

The invention belongs to the technical field of sanitary napkin production, in particular to a device for detecting water absorption of sanitary napkins. The following proposal is now proposed, including a base and a detection chamber. The detection chamber is fixed on the top outer wall of the base, and the two ends of the detection chamber are open. The detection chamber is provided with a water injection mechanism and a pressing water squeezing mechanism, and the bottom inner wall of the detection chamber is provided with a weighing device, and the pressing water squeezing mechanism is provided with a first electric guide rail horizontally fixed on the top inner wall of the detection chamber, and the first Both ends of the electric guide rail extend to both sides of the detection chamber, and the weighing device is arranged at the middle position of the first electric guide rail. The invention can detect the water absorption through the amount of water removed from the sample sanitary napkin, thereby avoiding the error caused by the judgment through quantitative water injection, better simulating the actual use situation by pressing the water, and comparing the water injection amount through the weight difference before and after the cloth is squeezed and absorbed It can be compared with the detection result of the weighing device to reduce the error.

Description

technical field [0001] The invention relates to the technical field of sanitary napkin production, in particular to a sanitary napkin water absorption detection device. Background technique [0002] Sanitary napkin is a kind of absorbent material, the main material is cotton, non-woven fabric, pulp or polymer composite paper formed by the composite of the above materials, and the side design is mainly used to prevent side leakage , because it will present a certain angle with the sanitary napkin body during use, and it is easier to rub against the groin. Therefore, sanitary napkins with soft materials on the side are more popular with women. The sanitary napkins are divided into three layers, namely the surface layer, The absorbent core, the bottom layer, and the back glue of the sanitary napkin are impermeable materials. [0003] During the production and processing of sanitary napkins, it is often necessary to sample sanitary napkins. The water absorption test of sanitary...

AI Technical Summary

Problems solved by technology

[0003] During the production and processing of sanitary napkins, it is often necessary to sample sanitary napkins. The water absorption test of sanitary napkins is an important part of the testing process. It is mainly used to measure the degree of adsorption of water or other liquids in sample sanitary napkins. In the prior art, in the process of testing the water absorption of sanitary napkins, the sanitary napkins are generally laid flat and fixed, and water is continuously added until the surface of the sanitary napkins overflows, and then the water absorption of the sample sanitary napkins is determined by measuring the amount of water added. However, there is an error in the judgment of water overflow during the actual detection process, which will affect the accuracy of the water absorption detection of the actual sanitary napkin
