Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to an automatic cloth deviation correction device for a laser cutting machine. Background Art

[0002] Fabric is a commonly used material in decoration, including chemical fiber carpets, non-woven wall coverings, linen, nylon, colored tape, flannel and other fabrics. Fabric plays a significant role in decorative display and is often a major force that cannot be ignored in the entire sales space. After being woven and formed through warp and weft, the fabric needs to be post-processed, such as dyeing and shaping, to solidify the physical properties of the product and meet the technical standards of customer product delivery, such as tear strength, stiffness, color fastness, etc. During the shaping process, the fabric width needs to be cut to meet the customer's door width requirements. When using laser to cut the fabric, if the fabric deviates during transportation, the cutting position will also shift. The solution is mostly for nearby staff to observe and determine whether the fabric is tilted or offset when cutting, and to stop the machine in time to manually pull and correct it.
