Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn tension detection technology, specifically a yarn tension detection device. Background Technology
[0002] Yarn tension testing is a crucial step in textile production. By testing yarn tension, we can ensure yarn consistency and quality, optimize production processes, and avoid problems such as yarn breakage and weaving defects caused by uneven tension. Yarn breakage often occurs during the weaving process, so it is necessary to conduct random checks on the yarn tension before weaving to reduce the risk of a large number of products being scrapped due to unqualified yarn tension.
[0003] However, existing methods for testing yarn tension either involve manually pulling the yarn, which can lead to inaccuracies in determining the actual tension due to varying operator strength, or using weights to stretch the yarn by adding weights and measuring the tension through scale lines on a connecting rod. This method requires frequent manual weight additions, is cumbersome, and yields inaccurate results, failing to meet inspection requirements.
[0004] Therefore, we propose a yarn tension detection device to solve the problems mentioned above. Utility Model Content
[0005] This invention provides a yarn tension detection device, which solves the problem mentioned in the background art that measuring yarn tension by manually pulling the yarn or by adding weights to rely on gravity is not only cumbersome to operate, but also results in poor accuracy of tension detection results.
[0006] This utility model provides the following technical solution: a yarn tension detection device, including a detection platform, a mounting base fixed on the detection platform, a dual-axis motor fixedly mounted on the mounting base, a tension detection mechanism fixedly mounted on the output shaft of the dual-axis motor, a tension sensor fixedly mounted on the tension detection mechanism by bolts, a winding assembly fixedly mounted on the tension sensor, the winding assembly being connected to the detection platform, a displacement mechanism fixedly mounted on the other output shaft of the dual-axis motor, a tension detection mechanism movably mounted on the displacement mechanism, a protective cover fixedly mounted on the detection platform at the displacement mechanism, and a shaft seat one and a shaft seat two fixedly mounted on the lower surface of the detection platform.
[0007] Preferably, the tensile testing mechanism includes a connecting shaft fixed on the output shaft of a dual-axis motor, a main pulley fixed on the connecting shaft, a belt movably sleeved on the main pulley, a secondary pulley movably sleeved inside the belt, a lead screw embedded in the secondary pulley, a threaded slider threadedly connected to the lead screw, a movable frame fixed on the threaded slider, a connecting member fixed on the movable frame, and a connecting flange threadedly fixed to the connecting member. The tensile testing mechanism includes a groove formed on the testing table.
[0008] Preferably, the movable frame includes a groove formed at the bottom, in which a pulley is embedded for rotation.
[0009] Preferably, the winding assembly includes a connecting block fixed to the tension sensor by bolts, a winding cylinder is fixed on the connecting block, and the winding cylinder has a winding groove.
[0010] Preferably, the winding assembly includes a fixing plate that is fixed to the testing table by bolts, a second connector is fixed on the fixing plate, and a second winding spool is fixed on the second connector.
[0011] Preferably, the displacement mechanism includes a second connecting shaft fixed to another output shaft of the dual-axis motor, a second main pulley fixed on the second connecting shaft, a second belt movably sleeved on the second main pulley, a second auxiliary pulley movably sleeved on the second belt, a second lead screw embedded in the second auxiliary pulley, a second threaded slider threadedly connected to the second lead screw, a translation frame fixed on the second threaded slider, and the displacement mechanism includes a second slide groove formed on the detection table.
[0012] Preferably, the tension detection mechanism includes an electric actuator embedded in the translation frame. The output end of the electric actuator is fixed with a second connecting flange. A pressure sensor is fixed to the second connecting flange by bolts. A connecting rod is fixed to the pressure sensor by bolts. A push plate is fixed to one end of the connecting rod. A pad made of rubber is fixed to the push plate. A telescopic sleeve is fixed at the gap between the translation frame and the push plate.
[0013] This utility model has the following beneficial effects:
[0014] The yarn can be automatically tensioned by a tension detection mechanism, a tension sensor, and a winding assembly. A dual-axis motor drives the shaft at one end to rotate, and the linkage between the belt and pulley rotates the lead screw to achieve the transmission purpose. This allows the yarn wound on the winding assembly to be stretched while moving. During the stretching process, the tension sensor monitors the tension data in real time, avoiding the detection errors that are prone to occur when checking yarn quality by hand or by adding weights.
[0015] Meanwhile, after the yarn tension test is completed, the electric push rod is activated to drive the push plate to move closer to the yarn. The pressure applied by the push plate can adjust the tension of the yarn in the straightened state. During the pushing process, the pressure data is monitored in real time by the pressure sensor to achieve dual detection of tension and stretching.
[0016] Furthermore, when the dual-axis motor is turned on to drive the connecting shaft at the other end to rotate, it can drive the displacement mechanism to rotate, allowing the tension detection mechanism to move on the detection table through the threaded engagement of the displacement mechanism. This allows the position during tension detection to be adjusted to ensure alignment with the center of the yarn. Attached Figure Description
