Wing folding system for sanitary napkin products

Abstract

The invention aims to provide a wing folding system for sanitary napkin products. The wing folding system comprises a cutting device, a conveying drum, a folding conveying device and a pressing rollerdevice. A single sanitary towel product is adsorbed on the surface of a transfer drum through the conveying drum; as the conveying drum rotates, the sanitary towel product is conveyed to the foldingconveying device; when the sanitary napkin product passes through a pressing area, tensioning rollers are used for pressing the protective wings on the two sides of the sanitary napkin product, the protective wings on the two sides are prevented from generating folded corners before entering the folding conveying device, and the flatness of the sanitary napkin product is guaranteed. In addition, apressing roller in the pressing roller device is arranged in an opening in the folding conveying device; when the cut-off wing release paper small pieces are pressed by the pressing roller device andare attached to wings of sanitary towel products, the negative pressure effect in the folding conveying device can be used for restraining the corner folding defect of the wing release paper, the flatness of the wing release paper is improved, the whole products are flawless, and the product quality is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing equipment for disposable sanitary products, in particular to the fields of sanitary napkins, panty liners and the like, and specifically relates to a flap folding system for sanitary napkin products. Background technique [0002] Disposable sanitary napkin product A generally has the structure of wing B on both sides of the product body, such as Figure 1a shown.

Since the two layers of the wing B are composited by sheets, it is very thin compared to the product body. Therefore, during the folding process, especially at high speeds, one or both sides of the wing B often have corners. C and other defects, such as Figure 1b as well as Figure 1c The collapsed state shown. [0003] Aft...

AI Technical Summary

Problems solved by technology

Since the product has been individually formed at this time, it would be too wasteful to discharge the entire product as waste. If the defect is not discharged, the product will have defects, which will greatly affect the quality of the product and will also affect the use.

[0004] Therefore urgently need to provide a kind of new flap folding system of sanitary napkin product, in order to solve defects such as knuckle in the process of flap folding.
