Description

Technical Field

[0001] This utility model belongs to the technical field of rear beams in textile machinery, and specifically relates to a rear beam structure that is easy to adjust. Background Technology

[0002] The back beam of textile machinery is a crucial component, especially in looms (such as rapier looms). It plays a key role in supporting and regulating warp yarn tension and maintaining fabric width stability during weaving. In actual weaving operations, the position of the back beam rollers needs to be adjusted back and forth, up and down, such as when weaving rovings and yarns. However, traditional looms mostly adjust the back beam rollers manually, often resulting in asynchronous left and right adjustments. This necessitates multiple fine-tunings to achieve the correct position, making back beam roller adjustment complex and time-consuming, which is detrimental to actual production.

[0003] Secondly, manual adjustments rely on the operator's experience and require manpower, increasing the operator's workload and hindering the achievement of reducing the operator's burden in actual production.

[0004] In summary, the traditional manual adjustment method for the position of the rear beam roller in textile machinery has certain problems. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content
