The top of the base has a groove, and a pulling mechanism for pulling the slide rod outwards is located within the groove. This machine can simultaneously test the tenacity of multiple cotton yarns, achieving automatic testing and improving testing efficiency.

[0004] Based on the aforementioned existing technology, the existing mechanisms for simultaneously testing the toughness of multiple cotton yarns still have the following problems: existing toughness testing mechanisms usually require feeding, testing, and unloading each yarn individually, and cannot simultaneously test the toughness of multiple cotton yarns. Therefore, this utility model provides a mechanism for simultaneously testing the toughness of multiple cotton yarns. Utility Model Content

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1-5 This utility model provides a technical solution: A mechanism for simultaneously testing the toughness of multiple cotton yarns includes a frame 1. The frame 1 has a multi-station testing mechanism 2 inside for performing toughness testing on multiple cotton yarns. The multi-station testing mechanism 2 includes: The moving unit 21 is located inside the frame 1 and is used to straighten and tighten the cotton yarn; The clamping unit 22 is located above the moving unit 21 and includes a mounting frame 221. A shelf 224 is fixedly installed inside the mounting frame 221. Five sets of moving columns 225 are slidably installed inside the shelf 224. A first upper clamping block 226 is fixedly installed at the bottom end of the moving column 225. A base frame 222 is fixedly installed above the mounting frame 221. Five sets of first lower clamping blocks 223 are fixedly installed at the top of the base frame 222. The moving columns 225 are pushed by the driving component 3 to clamp the first lower clamping blocks 223 relative to the first upper clamping blocks 226, thereby realizing the clamping and detection of multiple cotton yarns. The detection unit 23 is located above the moving unit 21 and is used to detect the toughness of the cotton yarn. By using the mounting frame 221, layer 224, five sets of moving columns 225, and matching first lower clamping block 223 and first upper clamping block 226, combined with the drive assembly 3 to push the moving columns up and down, the synchronous clamping and fixing of five cotton yarns is achieved. Its core effect is to upgrade the traditional single yarn clamping to multi-station parallel operation, and complete the positioning and fixing of multiple cotton yarns at one time through mechanical linkage.

[0014] The drive assembly 3 includes a fixed plate 32 fixedly installed above the front side of the sliding rod 211. A miniature cylinder 33 is fixedly installed on the front side of the fixed plate 32. The output end of the miniature cylinder 33 passes through the fixed plate 32 and is fixedly installed with a linkage plate 34. An inclined groove 35 is opened inside the linkage plate 34. A sliding column 31 is fixedly installed above the inside of the moving column 225. The sliding column 31 is located inside the inclined groove 35 and is adapted to slide. The lifting and lowering of the moving column 225 is achieved by the sliding column 31 moving along the trajectory of the inclined groove 35. The miniature cylinder 33, model DSNU-20-50-PPV-A, is electrically connected to an external power source and operates via a user-controlled control panel. The miniature cylinder 33 drives the linear motion of the linkage plate 34, which, through the coordination of the inclined groove 35 and the trajectory of the sliding column 31, converts the horizontal thrust into the vertical lifting and lowering of the moving column 225. Its innovative effect lies in using a single cylinder to drive the synchronous opening and closing of five sets of clamping blocks, simplifying the power source while ensuring the consistency of the clamping action timing. The inclined groove design amplifies the cylinder stroke into the clamping block displacement, enhancing the controllability of the clamping force and preventing the cotton yarn from breaking due to excessive instantaneous pressure. The bottom of the linkage plate 34 is provided with a T-shaped groove 37, and a T-shaped strip 36 is fixedly installed on the top of the shelf 224. The T-shaped strip 36 is located inside the T-shaped groove 37 and slides to limit the movement of the linkage plate 34. The T-shaped strip 36 and T-shaped groove 37 are nested and slide together to constrain the movement path of the linkage plate 34. Its core function is to eliminate the offset or swaying of the linkage plate during horizontal movement, ensuring that the inclined groove 35 is always precisely aligned with the sliding column 31. In effect, it directly improves the synchronization accuracy of the lifting and lowering of the five sets of clamping blocks, prevents uneven clamping force caused by the displacement deviation of the linkage plate, and avoids local slippage or force distortion of the cotton yarn.

[0015] The moving unit 21 includes a set of sliding rods 211 fixedly installed inside the frame 1. A sliding seat 212 is slidably installed on the surface of the sliding rods 211. A lead screw 213 is rotatably installed inside the frame 1. A motor 214 is fixedly installed on the right side of the frame 1. The right end of the lead screw 213 moves through the frame 1 and extends to the output end of the motor 214 and is fixedly connected thereto. The sliding seat 212 is threadedly rotatably installed on the surface of the lead screw 213. The motor 214, model KV3SF-8521F-WR, is electrically connected to an external power supply and is operated via a user-controlled control panel. The motor 214 drives the lead screw 213 to rotate, which in turn moves the threaded sliding seat 212 horizontally along the sliding rod 211. Its function is to provide controllable linear power for the stretching of cotton yarn.

[0016] The detection unit 23 includes a mounting plate 231 fixedly installed on the left side of the inner cavity of the frame 1, and a vertical plate 232 fixedly installed on the top of the mounting plate 231. Several tension sensors 233 are fixedly installed on the left side of the vertical plate 232. One end of the tension sensor 233 movably passes through the vertical plate 232 and is fixedly installed with a connecting block 234. A connecting seat 2310 is fixedly installed on the surface of the connecting block 234 by bolts. A fixing frame 235 is fixedly installed on the right side of the connecting seat 2310. A second lower clamping block 236 is fixedly installed inside the lower part of the fixing frame 235. A threaded toggle rod 237 is threadedly rotatably installed on the upper part of the fixing frame 235. The fixing frame 235 is rotatably installed at the bottom end of the threaded toggle rod 237. A limit post 238 is slidably installed on the top of the fixing frame 235. The bottom end of the limit post 238 is fixedly connected to the top of the second upper clamping block 239. The second lower clamping block 236 and the second upper clamping block 239 are installed opposite to each other.

[0017] The tension sensor 233 is model HBM U9B. The downward pressure of the second upper clamping block 239 is precisely adjusted by the threaded toggle 237, and the limit post 238 is used to prevent deflection, so as to transmit the tension of the cotton yarn to the independently connected tension sensor 233.

[0018] In this embodiment, a protective shell 227 is fixedly installed on the top of the mounting bracket 221 by bolts to protect the clamping unit 22 and the drive assembly 3.

[0019] By adding a protective shell 227, which is bolted to the top of the mounting bracket 221, physical isolation protection is provided for the clamping unit 22 and the drive assembly 3. This effectively prevents cotton fibers and dust from entering the precision transmission components, avoiding mechanical jamming; it also reduces external collision damage, extends the equipment's service life, and ensures the long-term stability of the multi-station clamping system.

[0020] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0021] During operation, firstly, one end of the five cotton yarns is placed between the first upper clamping block 226 and the first lower clamping block 223. The micro cylinder 33 is activated to push the linkage plate 34 to move. During the movement of the linkage plate 34, the sliding column 31 slides inside the inclined groove 35. The sliding column 31 drives the moving column 225 and the first upper clamping block 226 to move downward. The V-shaped block at the bottom of the first upper clamping block 226 clamps the cotton yarn into the V-shaped groove above the first lower clamping block 223, thus clamping and fixing the cotton yarn. Next, the other end of the cotton yarn is pulled out and tightened through the groove below the fixing frame 235 above the second lower clamping block 236. The limiting post 238 is rotated to drive the second upper clamping block 239 to move down. The V-shaped block at the bottom of the second upper clamping block 239 clamps the cotton yarn into the V-shaped groove above the second lower clamping block 236 to clamp and fix the cotton yarn. Then, the motor 214 runs, driving the lead screw 213 to rotate. The lead screw 213 drives the sliding seat 212 to move, pulling the cotton yarn through the clamping unit 22. The cotton yarn pulls the tension sensor 233 to detect the toughness.
