Description

Technical Field

[0001] This utility model relates to the field of fabric production, and more specifically, to a yarn guiding device for the production of lace fabrics. Background Technology

[0002] Fabric is the material used to make clothing. As one of the three elements of clothing, it not only interprets the style and characteristics of clothing, but also directly affects the color and shape of clothing. When producing fabric, yarn guiding devices are usually used to guide the yarn.

[0003] A search revealed that Chinese patent CN221720177U discloses a "yarn guiding device for fabric production," comprising: a base, a turntable rotatably connected to the top of the base, a fixing device fixedly installed on the top of the turntable, a tensioning device fixedly installed on one side of the fixing device, and a connecting rod fixedly installed on the top of the turntable, with a housing fixedly installed on the top of the connecting rod. In use, the yarn bobbin is fitted over the housing, the inner wall of the yarn bobbin drives the tensioning blocks to move inward, the two tensioning blocks drive the two drive rods to move inward, and the sliding block compresses the tensioning spring, causing the tensioning blocks to press against the inner wall of the yarn bobbin for clamping. This fixes the inside of the yarn bobbin, preventing the yarn from tangling on the fixing device when exiting the yarn loop, thus reducing the risk of yarn breakage. However, the following drawbacks still exist:

[0004] The clamping force relies on the spring, which has poor adaptability to yarn bobbins with different inner diameters. If the inner diameter of the yarn bobbin is too large or too small, it may cause unstable clamping or excessive tightness, which in turn affects the smooth output of the yarn. At the same time, the current design is only suitable for single yarn bobbins, which limits production efficiency.

[0005] Therefore, a yarn guiding device for the production of lace fabrics is proposed. Utility Model Content

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0026] Example: Figures 1-5 As shown, this embodiment proposes a yarn guiding device for lace fabric production, including: a yarn bobbin 1 and a yarn guiding seat 2. A yarn guiding component 3 for fixing the yarn bobbin 1 is rotatably mounted on the top of the yarn guiding seat 2, and a guide component 4 for assisting the yarn guiding component 3 in guiding the yarn is fixedly mounted on the top of the yarn guiding seat 2.

[0027] The yarn guiding assembly 3 includes a first motor 301 bolted to the bottom of the yarn guiding base 2. A rotating shaft 302 is mounted on the output end of the first motor 301. A turntable 303 is fixedly connected to the top of the rotating shaft 302, and a fixed base 304 is bolted to the top of the turntable 303. A second motor 305 is bolted to one side of the fixed base 304. A bidirectional screw 306 is mounted on the output end of the second motor 305. A fixing clamp 307 is slidably mounted on the bidirectional screw 306 via a slider. By starting the second motor 305, the bidirectional screw 306 is driven to rotate, causing the two fixing clamps 307 to move towards or away from each other in the groove. After the yarn bobbin 1 is placed above the fixed base 304, the fixing clamps 307 are operated to clamp and fix it from the inside of the bobbin. Then, the yarn guiding operation is performed. During the yarn guiding process, the first motor 301 is started, and the rotating shaft 302 drives the entire turntable 303, the fixed base 304, and the fixed yarn bobbin 1 to rotate slowly together to spread the yarn.

[0028] like Figures 1-4 As shown, the guide assembly 4 includes a first guide frame 401 bolted to the top of the yarn guide seat 2. A third motor 402 is bolted to one side of the first guide frame 401. A rotating rod 403 is installed at the output end of the third motor 402. A guide wheel 404 is provided on the outer side of the rotating rod 403. A second guide frame 405 is bolted to the top of the yarn guide seat 2. A limiting groove 406 is provided on the second guide frame 405, and a guide block 407 is fixedly installed in the limiting groove 406. A guide hole 408 is provided on the guide block 407. During the yarn guiding process, the yarn drawn from the yarn bobbin 1 is first initially positioned and guided by the groove 5 on the guide wheel 404. After the third motor 402 is started, the motor drives the rotating rod 403 to rotate, which in turn drives the guide wheel 404 to rotate. The guide wheel 404 plays an initial guiding and combing role for the yarn, ensuring that the yarn is transmitted in the predetermined direction. At the same time, the yarn will pass through the guide hole 408 on the second guide frame 405, and the guide block 407 can be adjusted appropriately in the limiting groove 406 to adapt to the guiding requirements of yarns of different specifications, thereby ensuring that the yarn remains stable during transmission.

[0029] like Figures 1-4 As shown, the rotating rod 403 is located inside the first guide frame 401, and the guide wheel 404 corresponds to the positions of the yarn bobbin 1 and the guide block 407. This ensures that the yarn drawn from the rotating yarn bobbin 1 can smoothly enter the guiding system at the optimal angle, avoiding sharp bends or friction against the edge of the bobbin, and ensuring smooth yarn guidance.

[0030] like Figures 1-4 As shown, a groove 5 is provided on the guide wheel 404. The yarn is led out from the yarn bobbin 1, positioned by the groove 5, and then passes through the guide hole 408. The groove 5 on the guide wheel 404 can effectively accommodate and constrain the yarn, preventing the yarn from slipping laterally on the guide wheel 404, and further enhancing the reliability of the guide.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, two sets of fixing clips 307 are symmetrically arranged on the inner side of the yarn spool 1, and the outer side of the fixing clips 307 is provided with anti-slip texture. The anti-slip texture greatly increases the friction between the fixing clips 307 and the inner wall of the yarn spool 1, making the clamping more secure and reliable, ensuring the balance of clamping force, and preventing the yarn spool 1 from swaying due to uneven force when rotating.

[0032] like Figures 1-4 As shown, a scale 6 is provided on the top of the yarn guide seat 2, and the scale 6 is located on the outside of the rotating shaft 302. The scale 6 provides a visual reference for the operator, which can accurately adjust and confirm the position of the yarn bobbin 1 or related components, facilitating standardized operation, quick bobbin changing and positioning, and necessary process adjustments.

[0033] like Figures 1-5 As shown, the outer contour of the fixing clamp 307 matches the inner contour of the yarn bobbin 1, and the fixing clamp 307 slides along the groove on the fixing seat 304. The fixing clamp 307 can fit against the inner wall of the bobbin with the maximum contact area, providing a uniform and strong clamping force, while the groove ensures the linearity and smoothness of the movement, realizing stable and efficient clamping and releasing actions.

[0034] Working Principle: This utility model provides a yarn guiding device for lace fabric production. The specific usage steps are as follows: Step 1: The operator places an empty or fully wound yarn spool 1 on the fixed base 304, so that it fits over the two sets of fixed clamps 307. The second motor 305 is started, driving the bidirectional screw 306 to rotate, causing the two sets of fixed clamps 307 to move outward synchronously along the slide groove until they are tightly attached to and clamp the inner wall of the yarn spool 1. The anti-slip texture ensures the firmness of the clamping. Step 2: The yarn end is drawn out from the yarn spool 1 and embedded into the groove 5 of the guide wheel 404 on the first guide frame 401. The yarn is then passed through the second guide wheel 404. The guide hole 408 in the guide block 407 on the frame 405 ensures that the yarn moves smoothly and unobstructed throughout the entire path; Step 3: The yarn drawn from the yarn bobbin 1 is first initially positioned and guided by the groove 5 on the guide wheel 404. After the third motor 402 is started, the motor drives the rotating rod 403 to rotate, which in turn drives the guide wheel 404 to rotate. The guide wheel 404 plays an initial guiding and combing role for the yarn, ensuring that the yarn is transmitted in the predetermined direction. The guide block 407 can be adjusted appropriately in the limiting groove 406 to adapt to the guiding requirements of yarns of different specifications, thereby ensuring that the yarn remains stable during transmission.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
