Description

Technical Field

[0001] The utility model relates to the field of cloth processing, and more specifically, to a cloth winding device. Background Art

[0002] Fabric is a commonly used material in decoration, including chemical fiber carpet, non-woven wall cloth, linen, nylon, colored tape, flannel and other fabrics. Fabric plays a significant role in decoration and display, and is often the main force that cannot be ignored in the entire sales space. The extensive use of fabric for wall decoration, partitions, and background processing can also form a good commercial space display style.

[0003] The fabric needs to be stored in large quantities and needs to be wound on a take-up roller;

[0004] For example, the patent (CN219507235U) discloses a cloth winding device, in which the electric telescopic rod drives the second plug block to be inserted into the second slot of the winding roller to fix the position of the winding roller; the abutment plate always abuts against the cloth on the winding roller, and as the thickness of the cloth on the winding roller increases, the abutment plate is driven to move up to ensure the stability of the cloth wound on the winding roller;

[0005] When using the above technology, it was found that the following technical problems exist in the prior art: when the thickness of the winding roller of the device increases, the spring will shrink, thereby increasing the pressure between the abutment plate and the fabric roll, thereby affecting the quality of fabric winding. For this reason, we designed a fabric winding device to provide another technical solution to the above technical problems. Utility Model Content
