[0002] Sanitary napkins are absorbent materials, primarily made of cotton, non-woven fabric, pulp, or a composite of these materials, forming polymers and polymer composite paper. The side design is mainly to prevent side leakage. Because they are at an angle to the sanitary napkin body during use, they are more prone to friction with the groin area. Therefore, sanitary napkins with soft side materials are more popular among women. On sanitary napkin production lines, adhesive residue may remain on the conveyor belt due to glue spillage or splattering. This residue is usually related to the type of adhesive used in the production process. Based on the sanitary napkin manufacturing process, the adhesive adhering to the conveyor belt is mainly hot melt adhesive residue. Currently, this requires manual scraping by workers, which is inconvenient and difficult to remove completely. Utility Model Content

The top wall of the processing box 6 acts as a pad, preventing the conveyor belt 1 from stretching and deforming during the adhesive removal process by the first scraper 13 and the second scraper 19, thus ensuring effective scraping.
[0030] Preferably, multiple embedded heating rods 8 are evenly arranged inside the top wall of the processing box 6 for heating the conveyor belt.
[0031] In this embodiment, a first partition wall 10 is located to the left of the first scraper 13, and a second partition wall 12 is located to the right of the first partition wall 10. The bottom of the first scraper 13 is locked into a groove at the top of the second partition wall 12 by screws, and the top of the first partition wall 10 is bent to the right. The first partition wall 10, the second partition wall 12, and the front and rear side walls of the processing box 6 form a collection space for the detached adhesive. An inclined first guide plate 14 is provided between the first partition wall 10 and the second partition wall 12. A first drawer 20 is provided at the bottom of the processing box 6, located between the first partition wall 10 and the second partition wall 12. The scraped adhesive falls along the first guide plate 14 into the first drawer 20 at the bottom of the processing box 6. By pulling out the first drawer 20, the adhesive inside can be cleaned.
