Description

Technical Field

[0001] The utility model relates to the technical field of yarn detection, in particular to a yarn strength detection device. Background Art

[0002] Yarn is a kind of textile, which is processed into a certain fineness from various textile fibers and used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short-staple yarn, continuous filament, etc. With the improvement of people's living standards, people have higher and higher requirements for the quality of clothes. In order to improve the quality of clothes, multiple strands of yarn are often blended into mixed yarn. The tensile strength of yarn needs to be tested during the production process.

[0003] Upon investigation, the Chinese utility model patent with publication number CN220040084U discloses a mixed yarn strength detection device. The structure of the detection device is composed of simple mechanical structures, so its manufacturing cost is much lower than the price of purchasing a precision electronic instrument, thereby achieving the effect of detecting the strength of the mixed yarn without the need for precision electronic instruments for testing, that is, the strength of the mixed yarn can be measured by the weighing principle, which is easy to use. Since this detection device is suitable for some cases where the number of uses is small, its labor cost can be ignored, which greatly reduces the cost of use and brings benefits to some users who use it less frequently. The device is in use. First, take a length of the mixed yarn to be tested, then wrap the upper end of the mixed yarn to be tested around the outside of the lower ring for several turns, then pass the upper end through the first threading hole and wrap it around the first threading groove for several turns before tying it, pass the lower end of the mixed yarn to be tested through the upper ring, the lower ring and the through hole, lift the weight placement plate upward to make it leave the upper surface of the buffer pad, and finally pass the lower end of the mixed yarn to be tested through the second threading hole and wrap it around the second threading groove for several turns before tying it. The detection device has a relatively cumbersome way of binding the two ends of the yarn, which will waste a lot of time during the detection process, and is not conducive to detecting large quantities of yarn.

[0004] Therefore, the utility model provides a yarn strength detection device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The utility model provides a yarn strength detection device, such as Figure 1-7 As shown, the detection device includes a detection mechanism 2 arranged in a frame plate 1;

[0032] The detection mechanism 2 includes a weight placement plate 21 disposed at the bottom of the frame plate 1 and thread end fixing members 22 disposed at the top of the weight placement plate 21 and the top of the frame plate 1 for fixing the two ends of the yarn respectively;

[0033] The thread end fixing member 22 includes a U-shaped fixing frame 221, a clamping ring 222 fixedly connected to the end of the U-shaped fixing frame 221, and a binding roller 224 movably clamped inside the clamping ring 222. A clamping groove 2241 is provided on the side of the middle part of the outer wall of the binding roller 224, and a clamping plate 225 is movably connected inside the clamping groove 2241. The clamping cooperation between the binding roller 224 and the clamping ring 222 can form a detachable fixing member. When in use, the yarn end can be fixed on the binding roller 224 in advance, and then the binding roller 224 can be clamped on the clamping ring 222, which can speed up the detection efficiency. At the same time, the side edges of the binding roller 224 are polished into a smooth arc surface to avoid causing marks on the yarn and affecting the yarn detection effect.

[0034] When in use, first open the clamping plate 225, then clamp the end of the yarn between the clamping plate 225 and the binding roller 224, then wrap the other end of the yarn around the outside of the binding roller 224 and the clamping plate 225 for several turns, then repeat the above operation and bind the other end of the yarn to another binding roller 224, then clamp the two binding rollers 224 on the clamping ring 222 respectively, and then place the corresponding weights in the weight placement plate 21 to detect whether the tensile strength of the yarn reaches the qualified state. After using weights of the same weight, check whether the mixed yarn to be tested is broken to determine whether the strength of the mixed yarn to be tested meets the standard. If the strength of the mixed yarn to be tested does not meet the standard, the mixed yarn will break, and at this time it will move downward under the guidance of the guide rod 31.

[0037] In order to prevent the yarn from tilting during the detection process, corresponding annular grooves 2243 are opened in the middle of the opposite side of the binding roller 224 and the clamping plate 225, which facilitates the positioning and binding of the yarn on the binding roller 224 and the clamping plate 225, thereby preventing the yarn from tilting during the detection process.

[0038] In order to increase the clamping force of the clamping plate 225 and the binding roller 224 on the yarn, a plurality of protruding rods 2251 are fixedly connected to one end of the clamping plate 225 facing the binding roller 224 at equal intervals in the vertical direction, and a groove 2242 corresponding to the protruding rod 2251 is opened inside the clamping groove 2241. The outer wall of the protruding rod 2251 and the side edges of the inner wall of the clamping groove 2241 are polished into smooth arc surfaces.

[0039] In order to prevent the yarn from moving out of the annular groove 2243 , a U-shaped ring 2244 is fixedly connected to the binding roller 224 and located at the annular groove 2243 .

[0040] In order to position the binding roller 224 on the clamping ring 222, both ends of the binding roller 224 are fixedly connected with fixing plates 2245, and the opposite ends of the fixing plates 2245 are respectively in contact with the opposite ends of the two clamping rings 222. The clamping rings 222 are clamped on the two ends of the binding roller 224, so that the binding roller 224 can be easily removed from the clamping ring 222.

[0041] In order to facilitate the guiding installation of the binding roller 224, an inclined guide roller plate 223 is fixedly connected to the outer side of the open end of the clamping ring 222. The two guide roller plates 223 form a wide-mouthed installation opening, which facilitates the guiding installation of the binding roller 224 into the interior of the clamping ring 222.
