[0002] Yarn is a kind of textile product, which is processed from various textile fibers into products with a certain fineness and is used for weaving, making ropes, making threads, knitting, embroidery, etc. It is divided into staple fiber yarn, continuous filament, etc.; wool yarn and wool thread are generally used for knitting wool sweaters, wool trousers, wool vests, scarves, hats and gloves and knitting various spring and autumn clothing items. In addition to warmth retention, they also have a decorative function. During the production process of yarn, the produced yarn needs to be cut into appropriate lengths, and a yarn shearing machine is required for cutting.

[0003] The patent with the national patent publication number: CN216585386U discloses a yarn shearing device for yarn production. This application proposes: "The existing yarn shearing devices generally have the problem of low shearing efficiency, which requires users to spend more time to complete the shearing of yarn, thus affecting the efficiency of users' subsequent yarn processing." Although this application solves this problem, it has the following defects:

[0004] When the yarn shearing device in the above application shears the yarn, the yarn is in a tensioned state. During shearing, the two ends will burst open under the action of elastic force, resulting in the phenomenon of loose ends at the shearing position after shearing, which affects the quality of the yarn. Therefore, we propose a yarn shearing structure. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides a yarn shearing structure, which can limit the two ends of the yarn through two pressing plates before shearing during use, and then shear through a shearing tool, so that the interfaces at both ends of the yarn after shearing are flat, without bursting open and the phenomenon of loose ends, ensuring the quality of yarn production.

Detailed implementation manners

[0024] The following further describes the embodiments of the present utility model with reference to the accompanying drawings.

[0025] Embodiment:

[0026] As Figures 1-5 shown, a yarn shearing structure includes a workbench 1, four groups of support legs 5 for support are fixedly connected to the bottom of the workbench 1, a mounting column 4 for fixing the shearing device is arranged on the top of the workbench 1, a shearing mechanism 2 for shearing yarn is fixedly connected to the left side of the mounting column 4, and a rotating assembly 3 for adjusting the position of the shearing device is fixedly connected to the bottom of the workbench 1.

[0027] The shearing mechanism 2 includes a housing 201, the housing 201 is fixedly connected to the left side of the mounting column 4, a tool holder 206 is arranged inside the housing 201, the top of the tool holder 206 is movably connected to a connecting rod 207 through a pin shaft, a stepping motor 213 is fixedly connected to the rear side of the housing 201, the stepping motor 213 is fixedly connected to a disc 205 through an output shaft, fixing plates 209 are fixedly connected to both the front and rear sides of the tool holder 206, a spring 212 is fixedly connected to the bottom of the fixing plate 209, and the bottom end of the spring 212 is fixedly connected to a pressing plate 210.

[0028] The working principle of the above technical solution is as follows:

[0029] When shearing the yarn, the stepping motor 213 drives the disc 205 to rotate through the output shaft. The rotation of the disc 205 can drive the tool holder 206 to perform reciprocating motion in the up and down directions under the action of the connecting rod 207. When the tool holder 206 moves downward, the two ends of the yarn are limited and flattened through the pressing plate 210. The yarn is sheared under the action of the tool below the tool holder 206. When it moves upward, the shearing of the yarn on the workbench 1 is completed.

[0030] In another embodiment, as Figure 3 shown, a limiting rod 211 is fixedly connected to the top of the pressing plate 210. The top end of the limiting rod 211 penetrates through the fixing plate 209 and is slidably connected to the fixing plate 209. A backing plate 208 is fixedly connected to the top of the workbench 1.

[0031] Under the action of the limiting rod 211, the moving track of the pressing plate 210 can be limited to ensure that it can only move in the up and down directions. Under the action of the backing plate 208, the workbench 1 is protected.

[0032] In another embodiment, as Figure 3 shown, a tension spring 203 is fixedly connected to the top of the tool holder 206. The tension spring 203 is fixedly connected to the inner top of the housing 201.

[0033] Under the action of the tension spring 203, the movement of the tool holder 206 is buffered and decelerated to ensure the normal stability of shearing and help improve the flatness of the cut.

[0034] In another embodiment, as Figure 3 shown, a fixed rod 202 is fixedly connected to the front side of the disc 205. A circular hole is formed in the front side of the connecting rod 207. The fixed rod 202 is movably connected to the inner side of the circular hole through a bearing.

[0035] Under the action of the fixed rod 202 and the connecting rod 207, when the disc 205 rotates, it can drive the tool holder 206 below the connecting rod 207 to perform reciprocating motion in the up and down directions, so as to cut the yarn.

[0036] In another embodiment, as Figure 3 shown, a vertical rod 204 is fixedly connected to the top of the tool holder 206. The top end of the vertical rod 204 penetrates through the top of the housing 201 and is slidably connected to the top of the housing 201.

[0037] Under the action of the vertical rod 204, the moving track of the tool holder 206 is limited to ensure that it can only move in the up and down directions.

[0038] In another embodiment, as Figure 2As shown in the figure, the rotating assembly 3 includes a servo motor 301. The servo motor 301 is fixedly connected to the bottom of the workbench 1. The servo motor 301 is equipped with an output shaft. The servo motor 301 is fixedly connected to a transmission rod 304 through the output shaft. The transmission rod 304 is fixedly connected to the bottom end of the mounting column 4.

[0039] Under the action of the servo motor 301, the mounting column 4 can be driven to rotate through the output shaft and the transmission rod 304, so that the yarns on both sides of the workbench 1 can be sheared respectively, ensuring the shearing efficiency.

[0040] In another embodiment, as Figure 2 shown, a mounting hole 303 is formed in the top of the workbench 1. An annular groove 302 is formed inside the mounting hole 303. A limiting ring 305 is fixedly connected to the outside of the mounting column 4. The limiting ring 305 is slidably connected to the inside of the annular groove 302. The top end of the transmission rod 304 penetrates through the bottom of the mounting hole 303 and is movably connected thereto through a bearing.

[0041] The mounting hole 303 facilitates the placement of the mounting column 4. Under the action of the limiting ring 305 and the annular groove 302, the position of the mounting column 4 can be limited to ensure its stability within the mounting hole 303.

[0042] The above embodiments only illustrate the specific implementation manners of the present invention, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several variations and improvements can still be made, and these all belong to the protection scope of the present invention.
