During the conveying process of the sanitary napkin raw materials, when the sanitary napkin raw materials move to the bottom of the rolling columns 9, the rolling columns 9 are located above the middle position of the side of the sanitary napkin raw materials, and the conveyor belt 1 1 Stop conveying the sanitary napkin raw material, start the electric telescopic rod 5 to work, the output end of the electric telescopic rod 5 drives the bottom plate 4 to move downward, and the bottom plate 4 drives the two base blocks 7 to move downward synchronously during the downward movement. The two base blocks 7 drive the rolling columns 9 to move downward through the metal arc spring pieces 6 on the bottom ends and press against the two sides of the sanitary napkin raw material. The electric telescopic rod 5 continues to drive the rolling columns 9 to move downward, so that the metal arc spring pieces 6 produce elastic deformation, so that the rolling columns 9 on the bottom ends of the two metal arc spring pieces 6 on the same base block 7 automatically expand outward. Rolling, through the synchronous outward expansion and rolling of four rolling columns 9, the two sides of the sanitary napkin raw material are synchronously rolled and pressed, and the side edges of the sanitary napkin raw material are automatically pressed. The rolling columns 9 effectively tighten the side edges of the sanitary napkin raw material during rolling, thereby flattening the side edges of the sanitary napkin raw material, removing wrinkles, and improving the quality of the finished product. When the rolling columns 9 are rolling, the scraping component 1 scrapes off the residues adhering to the side of the rolling columns 9, so that the rolling columns 9 will not cause dents on the pressed edges of the sanitary napkin due to the residues, thereby reducing the production scrap rate.

[0023] Further as Figure 4 and Figure 5As shown, it is worth explaining in detail that the scraping assembly 1 includes a connecting rod 103 fixed on the connecting plate 10, an upper connecting plate 105 is fixed on the side of the bottom end of the connecting rod 103, an arc plate 102 is fixed on the bottom end of the upper connecting plate 105, and a scraper plate 101 in contact with the side of the rolling column 9 is fixed on the end of the arc plate 102 away from the upper connecting plate 105; when the rolling column 9 is rolling, the rolling rolling column 9 and the scraper plate 101 form a relative movement, and the scraper plate 101 is used to scrape off the residues adhered to the side of the rolling column 9, and the scraped residues are collected and stored by the arc plate 102 for easy cleaning, so that the rolling column 9 will not cause dents on the edge of the sanitary napkin due to the residues, thereby reducing the production scrap rate.

[0024] Further as Figure 4 and Figure 5 As shown, it is worth explaining in detail that the scraper plate 101 is arranged along the length direction of the rolling column 9 and the length of the scraper plate 101 is set equal to the length of the rolling column 9; during specific operation, by setting the length of the scraper plate 101 equal to the length of the rolling column 9, it can be ensured that all residues on the side of the rolling column 9 can be scraped off by the scraper plate 101.

The output end of the electric telescopic rod 5 drives the bottom plate 4 to move downward. During the downward movement, the bottom plate 4 drives the two base blocks 7 to move downward synchronously. The two base blocks 7 drive the rolling column 9 to move downward and press against the two side edges of the sanitary napkin raw material through the metal arc spring pieces 6 on the bottom ends. The electric telescopic rod 5 continues to drive the rolling column 9 to move downward, thereby causing the metal arc spring pieces 6 to produce elastic deformation, so that the rolling columns 9 on the bottom ends of the two metal arc spring pieces 6 on the same base block 7 automatically expand and roll outward. The four rolling columns 9 are synchronously expanded and rolled to synchronously roll and press the two sides of the sanitary napkin raw material, and the side edges of the sanitary napkin raw material are automatically pressed. The rolling columns 9 effectively tension the side edges of the sanitary napkin raw material during rolling, thereby flattening the side edges of the sanitary napkin raw material and removing wrinkles. When the rolling columns 9 are rolling, the rolling rolling columns 9 and the scraper plate 101 form relative movement, and the scraper plate 101 is used to scrape off the residues adhering to the side of the rolling columns 9, and the scraped residues are collected and stored by the arc plate 102 for easy cleaning. Therefore, the rolling columns 9 will not cause dents on the edge of the sanitary napkin due to the residues. When the edge pressing of the sanitary napkin raw material is completed, the output end of the electric telescopic rod 5 drives the bottom plate 4 to move upward, thereby driving the metal arc spring piece 6 and the rolling columns 9 to reset, and the conveyor belt 11 continues to convey forward. The conveyor belt 11 conveys the next sanitary napkin raw material to the bottom of the rolling column 9 for the next edge pressing operation.

[0028] Further as Figure 4 and Figure 5 As shown, it is worth explaining in detail that a chamfer is provided on the end of the scraper plate 101 that contacts the side of the rolling column 9; during specific operation, the provided chamfer enables the scraper plate 101 to better scrape off the residues adhered to the side of the rolling column 9, thereby improving the scraping effect.

[0029] In summary: the metal arc spring piece 6 generates elastic deformation, so that the rolling columns 9 on the bottom ends of the two metal arc spring pieces 6 located on the same base block 7 automatically expand and roll outward, and the four rolling columns 9 synchronously expand and roll outward to synchronously roll and press the two side edges of the sanitary napkin raw material, and automatically press the side edges of the sanitary napkin raw material. The rolling columns 9 effectively tension the side edges of the sanitary napkin raw material during rolling, thereby flattening the side edges of the sanitary napkin raw material, removing wrinkles, and improving the quality of the finished product. When the rolling columns 9 are rolling, the scraping component 1 scrapes off the residues adhering to the side of the rolling columns 9, so that the rolling columns 9 will not cause dents on the pressed edges of the sanitary napkin due to the residues, thereby reducing the production scrap rate.
