Description

Technical Field

[0001] The utility model belongs to the technical field of yarn guide devices, in particular to a yarn guide device with adjustable width. Background Art

[0002] The yarn guide device is a key component in textile machinery, mainly used to guide the yarn to maintain the correct path during the textile process to prevent the occurrence of problems such as yarn disorder, entanglement, and breakage. However, most of the yarn guide devices commonly used in production can only adapt to a single type of yarn and cannot adjust the width according to actual conditions. The width of yarns of different types and different process requirements will vary. If the width of the guide device is not adjustable, it cannot adapt to yarns of different widths, resulting in the inability to effectively guide and control the position and direction of the yarn.

[0003] Secondly, the yarn guide device that cannot adjust the width will make the same equipment unable to adapt to various production needs, increase the cost of the factory to purchase different equipment, and reduce the utilization rate and economic benefits of the equipment.

[0004] In addition, when production requirements change, the entire guide device may need to be replaced to meet the new yarn width requirements, rather than simply adjusting the problem, which will undoubtedly increase the company's maintenance and replacement costs.

[0005] In summary, the yarn guide device that cannot adjust the width has some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
