Description

Technical Field

[0001] The utility model relates to the field of tension correction devices, in particular to a tension correction device for a warping machine creel. Background Art

[0002] Warping machines are a type of mechanical device that plays an important role in the textile industry. They are mainly used for warp weaving. Their basic function is to tear off the pulp from single-strand warps on a large number of wool yarns or blended fabrics, straighten them, and then rewind them onto the warping cylinder to form "warping". In the textile process, yarn tension is crucial. Maintaining appropriate tension is a necessary condition to ensure normal twisting and winding. Excessive tension will not only increase the power consumption of each spindle, but also lead to an increase in yarn breakage. On the other hand, too little tension will reduce the winding density, affect the strength of the spun yarn, and may lead to problems such as increased yarn hairiness, poor gloss, and unstable operation of the wire ring.

[0003] Existing warping machine creel tension correction devices usually change the tension by moving the guide frame, and change the frame position by manually turning the gear or fixing it with bolts to keep the yarn at a certain tension. Some warping machine creel tension correction devices use a guide wheel as a follower, and the yarn is wound around the outside of the guide wheel to play a guiding role and avoid yarn mixing and entanglement.

[0004] On the one hand, the existing method of manually moving the guide frame requires repeated manual operation and adjustment. Since the tension of each group of yarns is different, it is easy for some yarns to have insufficient tension or breakage due to improper operation. On the other hand, the existing driven guide wheels are usually fixed to the frame with bolts. Replacing the guide wheels after they are worn requires a lot of manpower to replace several groups of guide wheels, and the replacement efficiency is low. Therefore, a warping machine creel tension correction device is proposed to solve the above problems. Utility Model Content
