Description

Technical Field

[0001] The utility model belongs to the technical field of steel cord production detection, and in particular relates to a steel cord twist measurement device. Background Art

[0002] The lay pitch of steel cord refers to the straight-line distance between the starting and ending points of the steel wire or the rope strands rotating around the core (i.e. 360°) during the twisting process. During the twisting process, the steel wire or rope strands are driven by the body of the twisting equipment to rotate in a uniform circular motion, and are driven by the traction wheel to move in a uniform linear motion while twisting, that is, to become rope strands (referred to as strands) or steel wire ropes. The steel wire in the strands and the strands in the steel wire rope present a cylindrical spiral state. The lay pitch is an extremely important twisting process parameter of steel cord, which has a significant impact on the structural performance and output of steel cord.

[0003] According to the patent application number 201922150573.3, a steel cord twist detection device is disclosed for detecting the twist of the steel cord. The steel cord twist detection device includes an untwisting mechanism and a toggle mechanism. The untwisting mechanism includes a base and a fixing mechanism. The fixing mechanism includes a first fixed shaft and a second fixed shaft relatively mounted on the base. The second fixed shaft is rotatably connected relative to the base. The steel cord is fixed between the first fixed shaft and the second fixed shaft. A take-up wheel is installed on the second fixed shaft. The toggle mechanism includes a support seat arranged on one side of the base, a slider slidably engaged with the support seat, an untwisting rod installed on the slider, a fixed pulley installed at one end of the support seat, and a steel cable. One end of the steel cable is connected to the slider, and the other end of the steel cable is connected to the take-up wheel after passing around the fixed pulley. An elastic member is telescopically arranged between the slider and the support seat.

[0004] Although the above technical scheme solves the problems of large limitations, low measurement accuracy and large errors in measuring the lay length of steel cords in existing devices, the above technical scheme cannot ensure that the clamping positions of the steel cords at both ends are consistent during measurement. If the clamping positions of the two ends of the steel cord are inconsistent, then when measuring the lay length, the starting point and ending point of the rotation of the steel wire or rope strand around the center will be offset, which will cause the measured lay length value to deviate from the actual value, thereby affecting the accuracy of the measurement results, and there are certain shortcomings.
