Description

Technical Field

[0001] The utility model relates to the technical field of medical textile material processing, and particularly relates to a cutting device for medical textile materials. Background Technique

[0002] Medical textile materials are based on textile materials and rely on modern processing and forming technologies. They are applied in the fields of medical treatment, hygiene, and healthcare, providing protection and repair functions for the human body. These materials must have the basic properties of being non-toxic, non-immunogenic, non-carcinogenic, having good mechanical properties, being easy to process and form, having high biocompatibility, being able to effectively protect against bacteria and viruses, and not polluting the environment.

[0003] Medical textile materials can be classified into four major categories of products according to their uses: non-implantable materials, implantable materials, extracorporeal devices (such as artificial kidneys, etc.), and medical and hygienic textiles (such as gauze, doctor's work clothes, surgical towels, etc.); according to different processing techniques, they can be divided into ordinary textiles, non-woven fabrics, knitted fabrics, and special fabrics.

[0004] In the medical and health field of our country, the demand potential for textile materials is huge, and the industry scale continues to grow. However, the comprehensive technical performance of medical textile materials still cannot fully meet the market demand. Especially in the field of surgical implantable textiles and extracorporeal filtration textiles, currently, they mainly rely on imports. Since textile materials are generally light in weight, soft / fluffy, and have a certain elasticity, there are problems such as low efficiency and insufficient product size accuracy in the cutting process of high-end surgical implantable medical textile materials. In addition, a cutting pad is used in the cutting equipment to protect the blade and extend the service life of the blade. No matter what material the pad is made of, impurities will be generated during the cutting process and adhere to the product. Therefore, the pad needs to be replaced regularly. For the above problems, a cutting device for glass fibers with the Chinese patent publication number: CN220179483U includes a workbench main body, a feeding device, a cleaning device, a stretching device, a cutting device, and a material receiving device. It is processed by setting a cleaning device to reduce the impurities attached to the product, but it is impossible to completely avoid the introduction of impurities; in addition, the stretching device and the cutting device controlled by an external electronic control device accurately grasp the cutting positions of different lengths of fabrics or wires, but it is not conducive to the accurate size control of knitted fabrics with large elasticity; a precise cutting device for glass fibers with the Chinese patent publication number: CN220467827U includes a workbench, a fixed rod, an installation rod, a pressing block, an empty groove, a spring, a limit groove, and a limit block. This device can improve the accuracy of glass fibers, but the groove design in this device is only vertically distributed and can only perform one-way cutting, and its production efficiency is low for the cutting of rectangular products.
