Description

Technical Field

[0001] This utility model relates to the field of mesh cutting technology, and in particular to a mesh cutting and stretching device. Background Technology

[0002] In the textile industry, mesh fabric is widely used in various fields, such as construction, decoration, and sports equipment. Traditional mesh fabric cutting and stretching processes mostly rely on manual operation. During the cutting process, the operator simply lays the mesh fabric flat on an operating platform, presses it down to fix it, and then the cutting device cuts it. It is difficult to guarantee the accuracy and consistency of cutting and stretching. During cutting, the mesh fabric may shift or shake, resulting in a deviation between the final cut shape and the expected design. This deviation not only affects the appearance and quality of the product, but may also lead to incompatibility in subsequent processing, requiring manual secondary trimming. In severe cases, it may even directly lead to product scrapping. This is undoubtedly a huge waste of raw materials, and also increases production costs and time costs. Utility Model Content
