Description

Technical Field

[0001] The utility model relates to the technical field of sanitary napkin products, and more specifically to a multi-layer composite conveying device for preventing cracking of a water-absorbing paper core. Background Art

[0002] Diapers are daily necessities commonly used by babies. They are another name for diapers, paper diapers or pull-up pants. Dry diapers can keep babies sleeping all night. Due to their strong water absorption, they are commonly known as "diapers". The absorbent paper core of diapers contains super absorbent polymer (SAP for short), which has an amazing water absorption and water storage capacity.

[0003] Existing absorbent paper cores are generally multi-layer composite cores. When the composite cores are transported on the production line, the superimposed cores are pressed together by the pressing components on the absorbent paper core conveying device so that the cores of different layers are tightly attached to each other while avoiding cracking during transportation. After being used for a period of time, the pressing belt becomes loose and needs to be replaced. Frequent replacement is labor-intensive and costly. Utility Model Content
