Description

Technical Field

[0001] The utility model relates to the technical field of sanitary napkin production, in particular to an auxiliary feeding device for a raw material layer of a sanitary napkin. Background Art

[0002] Sanitary napkins are a kind of sanitary products, which are mainly composed of three layers of raw materials such as a surface layer, an absorbent core layer, and a bottom layer, and an auxiliary feeding device. When sanitary napkins are produced, the raw material layers of the sanitary napkins need to be fed through a feeding device.

[0003] For example, an auxiliary feeding device for a sanitary napkin raw material layer with an authorization announcement number of CN218899946U includes a steering mechanism and a transmission mechanism arranged in sequence along the feeding direction; the steering mechanism includes a mounting carrier, and the above-mentioned document can achieve the effect of preventing the raw material layer from turning over during the transmission process and ensuring the product quality; however, when in use, the feeding device guides the sanitary napkin raw material layer in a guide ring during the feeding process of the sanitary napkin raw material layer. Since the tension of the sanitary napkin raw material layer changes during the feeding, the sanitary napkin raw material layer becomes loose, and the loose sanitary napkin raw material layer cannot be tensioned to avoid the sanitary napkin raw material layer from piling up, thereby reducing the feeding effect of the feeding device; at the same time, when the feeding device feeds the sanitary napkin raw material layer, the sanitary napkin raw material layer is limited by the limiting plates on both sides of the rotating roller. Since the two limiting plates are fixed to the transmission roller, the distance between the two limiting plates cannot be adjusted, and the sanitary napkin raw material layer of the same width is fed between the transmission rollers, thereby reducing the practicality of the feeding device.
