Tension adjusting structure for warping machine

Abstract

According to the tension adjusting structure for the warping machine, through the arrangement of a plurality of transmission rollers, an adjusting assembly and a tension measuring sensor, when yarn is conveyed between a warp bobbin and a spindle, the yarn sequentially and continuously bypasses the upper portions of the transmission rollers and the lower portions of the adjusting rollers, so that the yarn forms a continuously-bent W shape; the yarn between every two adjacent transmission rollers penetrates through one tension measuring sensor, so that the tension of each section of yarn is detected by the tension measuring sensor in real time, and when the tension of each section of yarn is too large or too small, the corresponding tension measuring sensor feeds back the tension to the controller; the controller drives the lifting plate to ascend and descend by controlling the electric telescopic rod in the adjusting assembly to stretch out and draw back, and then drives the adjusting roller to ascend and descend to adjust the tension of the yarn, so that the tension of each section of yarn can be adjusted in real time, the instantaneous change of the tension of the yarn can be more accurately controlled, and good warping quality is guaranteed.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile equipment, in particular to a tension adjusting structure for a warping machine. BACKGROUND

[0002] A warping machine is an important device in the textile industry for arranging yarns. Its main function is to evenly place yarns from spindles or spindle tubes onto warp rods or warp tubes, and to adjust the tension and tightness of the yarns to ensure smooth transmission and neat arrangement of the yarns. The quality of the warping process directly affects the stability of the subsequent weaving process and the quality of the finished fabric, so higher requirements are placed on the performance of the warping machine.

[0003] Currently, the tension of yarns during placement and transmission on traditional warping machines is mainly adjusted manually by operators. The operators need to manually adjust the tension control device based on experience and actual conditions to maintain the stability of the yarn tension. However, due to differences in operator skill levels and subjective factors, the manually adjusted tension is not stable, which may lead to uneven yarn tension, and in turn cause problems such as yarn breakage, yarn interlacing, and uneven arrangement. This not only reduces the warping efficiency, but also may affect the fabric quality during weaving.

[0004] In addition, during a long production process, operators need to continuously monitor and adjust the yarn tension to ensure the warping quality, which is labor-intensive. Especially on high-speed warping machines, the instantaneous changes in yarn tension are more difficult to accurately control by humans, further increasing the uncertainty of production.
