[0002] As a common material, cotton pads are widely used in many fields such as medical treatment, hygiene, and beauty. With the rapid development of these industries, the demand for cotton pads is also increasing, and at the same time, higher requirements are placed on the production efficiency of cotton pads.

[0003] In the traditional cotton sheet processing process, mechanical tools are usually used for cutting. Although this cutting method can achieve basic cutting functions, it has some problems. First of all, the traditional cutting method can often only perform a single longitudinal or transverse cut, and multiple operations are required to complete the cutting of the entire cotton sheet, resulting in low production efficiency. In addition, after the traditional cotton sheet is cut, it is usually necessary to remove it manually or with a simple mechanical device. This method is not only inefficient, but also easily causes damage or contamination to the cotton sheet during the removal process. In order to solve the above problems, we propose a cotton sheet cutting and ejecting device. Utility Model Content
