[0008] Main body components;

[0009] A moving part, the moving part is mounted on the main assembly;

[0010] A measuring piece, the measuring piece is arranged in the middle of the upper part of the main body component;

[0011] A movable part, wherein the movable part is installed inside the main assembly;

[0012] A reset member, the reset member being located at the front end of the moving member;

[0013] A driving member connected to the resetting member;

[0014] A pull-down member is arranged at the front end of the main body component.

[0015] The measuring device is moved by arranging a moving part on the main component, and a measuring part is arranged on the front side of the slideway to measure the yarn tension, so that the yarn tension can be automatically measured, and the yarn tension measurement can be assisted by the reset part and the driving part.

[0016] As a further solution of the present invention: the main body assembly includes an L-shaped plate, a wire groove opened on the top of the L-shaped plate, a vertical plate installed at the front end of the L-shaped plate, a wire take-up plate located above the vertical plate, and a yarn body passing through the wire take-up plate;

[0038] Wherein, the fourth mounting plate is located in front of the third mounting plate;

[0039] Wherein, the third spring is sleeved on the rotating shaft, and one end of the third spring is fixed on the fourth mounting plate.

[0040] By providing the third spring, the rotation shaft can be driven to rotate through the extension and contraction of the third spring, and the first gear installed on the rotation shaft can rotate synchronously.

[0041] As a further solution of the present invention: the pull-down member includes a movable groove opened on the vertical plate, a second gear rotatably mounted on the side of the bottom of the movable groove, a mounting shaft mounted on the second gear, and a movable rod sleeved on the mounting shaft;

[0043] By providing the second gear and the movable rod, when the first gear rotates, the second gear rotates synchronously, and the mounting shaft on the second gear rotates along with the second gear, which can drive the movable rod to rotate.

[0044] As a further solution of the present invention: the pull-down member further comprises a connecting plate connected to the movable rod and a fixed sleeve plate installed in the middle of the movable groove;

[0045] The connecting plate is connected to the wire take-up plate through the fixed sleeve plate, a fixed shaft is installed at the bottom of the connecting plate, and the movable rod rotates on the fixed shaft and the installation shaft of the connecting plate.

[0046] By setting a connecting plate and a fixed sleeve plate, the movable rod stretches the connecting plate, and the connecting plate moves up and down in the fixed sleeve plate to drive the take-up plate to move up and down, which is convenient for driving the yarn body downward to measure the tension.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] The measuring structure is supported by a support plate, and a slideway, a through hole, a first hydraulic rod and a second hydraulic rod are arranged on the L-shaped plate to move the support plate. The first hydraulic rod pushes the support plate to move left and right in the slideway, and the second hydraulic rod pushes the support plate from the through hole to the groove formed by the limit plate to stop, so that the measuring device can measure the tension of multiple yarns and avoid the need for manual holding. When the support plate approaches the third mounting plate, the second spring is linked to contract, and the contraction of the second spring can relax the pull rope, and the height of the yarn body is adjusted downward through the interaction of the first gear, the second gear and the movable rod. The yarn body and the measuring device are placed in the same position, which is convenient for measuring the yarn body one by one; and when the support plate reaches the front end of the groove formed by the limit plate, the vertical rod can be linked to push the arc rod, and the vertical rod applies force to the arc rod, which can facilitate the measuring wheel to clamp and measure the yarn body. When the support plate does not leave the groove formed by the limit plate, the measuring wheel and the guide wheel are always in a clamped state. After the measurement is completed, the second hydraulic rod contracts, and the second spring stretches and resets to push the support plate away. The force applied by the linked vertical rod to the arc rod disappears, and the clamping force of the measuring wheel on the yarn body is relaxed, avoiding the need for manual clamping and adjustment of the yarn body, thereby improving the degree of automation of the device.
