Description

Technical Field

[0001] This utility model relates to the field of fabric rolling, and in particular to a fabric rolling mechanism for a knitting machine used for automotive fabrics. Background Technology

[0002] With the booming development of the automotive manufacturing industry, the production quality and efficiency of automotive interior fabrics are receiving increasing attention. Knitted fabrics, with their softness, comfort, and breathability, have become a popular choice for automotive interiors. However, there are currently many problems to be solved in the fabric winding process of knitting machines used for automotive fabrics.

[0003] Existing knitting machine fabric winding mechanisms are prone to wrinkling during fabric transport, severely affecting the fabric's smoothness and the quality of subsequent processing. Wrinkled fabric not only diminishes the aesthetics of car interiors but can also lead to uneven wear and tear during use, reducing the fabric's lifespan.

[0004] Some fabric cutting mechanisms require frequent adjustments to the blade spacing to obtain fabrics of different sizes. However, with current technology, each blade adjustment necessitates disassembling the entire cutting mechanism, making the process extremely cumbersome. This not only wastes a significant amount of time and reduces production efficiency but also demands a high level of operator skill. Improper operation can further affect the precision of the cutting mechanism, consequently impacting the fabric cutting quality.

[0005] Some fabric winding machines use only a box-type winding mechanism to collect the fabric, requiring manual operation throughout the process. This is time-consuming, increases labor costs, and is extremely inefficient. More importantly, these winding mechanisms lack cleaning mechanisms, making the fabric highly susceptible to dust, impurities, and other dirt during the winding process. As the fabric is continuously rolled up, this dirt is drawn into the fabric, causing contamination and severely impacting the cleanliness and quality of automotive interior fabrics, failing to meet the stringent requirements for high-quality materials in automotive interiors.
