Abstract
Description
Technical Field
[0001] This utility model relates to the field of knitted fabric roll technology, and in particular to a double-width large roll knitted fabric roll structure. Background Technology
[0002] A knitted fabric roll structure is a support device for processing knitted fabric rolls. Knitted fabric is a fabric formed by bending yarns into loops and interlocking them using knitting needles. It is divided into warp-knitted fabric and weft-knitted fabric. After processing, it needs to be rolled up. Knitted fabric is generally woven using a circular knitting machine. During the weaving process, the fabric is wound into a roll as shown in the figure and becomes cylindrical. During the loading, unloading, handling, and transportation of the fabric, the fold lines become very obvious, especially for sensitive fabrics. Even a simple fold will leave obvious marks. The fold on the left side will leave marks in subsequent processing. Splitting the fabric immediately after weaving can reduce the impact of folds on the fabric quality. However, most fabrics will curl at the edges. Curling at the edges will cause color differences during dyeing. Therefore, the fabric cannot be split before dyeing. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of knitted fabric roll structures.
[0003] Existing knitted fabric roll-up structures have certain drawbacks. First, they are relatively simple, only able to roll one set at a time, resulting in low efficiency and inconvenience for users. Second, they have low automation, which negatively impacts practical use. To address this, we propose a double-width large-roll knitted fabric roll-up structure. This structure enlarges the cylinder, splits one cylinder into two pieces of fabric, and places the creases along the split lines to eliminate the influence of the center crease.
