Description

Multi-station tensioning structure for circular knitting machine knitted fabric production Technical Field The utility model relates to a multi-station tensioning structure for producing circular knitting machine knitted fabric, and belongs to the field of circular knitting machine knitted fabric production equipment. Background The multi-station tensioning structure for the production of the circular knitting machine knitted fabric is an equipment component applied to the production process of the circular knitting machine knitted fabric, and aims to ensure that the fabric keeps proper tension in production, clear generated burrs and improve production quality and efficiency. In the existing circular knitting fabric production process, a large amount of burrs are generated. When the existing tensioning structure conveys knitted fabric and carries out tensioning adjustment, burrs are easy to adhere to the tensioning roller and pollute the fabric again along with the rotation of the tensioning roller, even if a part of equipment is provided with a negative pressure adsorption cleaning device, part of burrs can still be adsorbed on the roller surface of the tensioning roller due to static electricity, so that the collection efficiency of the burrs is reduced, the processing quality of the fabric is influenced, and the defective rate of the fabric is increased.
