Description

Technical Field

[0001] This utility model relates to the technical field of sewing thread production equipment, and more specifically, to a thread feeding structure for sewing thread production. Background Technology

[0002] Sewing thread is used to sew together various clothing fabrics and other accessories. It has both practical and decorative functions. Since sewing thread is produced by weaving yarn, a yarn feeding structure is needed to transport the yarn during the production process.

[0003] The existing yarn feeding structure has the problem of inconvenient tension adjustment during yarn feeding, which leads to uneven tension and density of the sewing thread produced. In addition, the lack of guidance and combing during continuous yarn feeding makes it easy for knots to occur due to tension differences, which is not conducive to ensuring the weaving quality of the sewing thread.

[0004] Based on this, a yarn feeding structure for sewing thread production is proposed. Summary of the Invention

[0005] The main objective of this invention is to provide a yarn feeding structure for sewing thread production, so as to overcome the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a yarn feeding structure for sewing thread production, including a support frame. A shaft is inserted and installed through the upper part of the outer surfaces of the support frame that are close to each other. A plurality of fixing rings are uniformly fitted and fixedly installed on the outer surface of the shaft. Universal ball seats are fixedly installed at the middle of the front end and the rear end of the outer surface of the fixing rings. A fixing rod is fixedly installed at the middle of the lower surface of the fixing ring.

[0007] A universal ball is movably embedded in the inner surface of the universal ball seat. A connecting rod is fixedly provided at the middle of the outer surface of the universal ball away from the universal ball seat. A support frame is fixedly provided at the other end of the connecting rod. A locking wheel is fixedly installed on the outer surface of the fixed rod.

[0008] A guide wheel is movably fitted in the middle of the outer surface of the locking wheel. Positioning holes are opened through the middle of the four sides of the upper and lower surfaces of the locking wheel. A sleeve is movably inserted into one side of the outer surface of the locking wheel.

[0009] Positioning rods are movably inserted into the upper and lower parts of the inner surface of the sleeve. Positioning blocks are fixedly provided at the far ends of the positioning rods. The positioning blocks are embedded in the positioning holes. A first compression spring is movably sleeved on the middle of the outer surface of each positioning rod. One end of the first compression spring is connected to the outer surface of the positioning block, and the other end of the first compression spring is connected to the outer surface of the sleeve. A second compression spring is fixedly installed at the close ends of the positioning rods. A limit wheel is movably sleeved on the outer surface of the sleeve.

[0010] As a further improvement of this utility model, the lower surface of the support frame is provided with several limiting slots, both ends of the shaft extend outward through the support frame, and locking screw rings are spirally sleeved and fixedly installed on the outer surfaces of both ends of the shaft.

[0011] As a further improvement of this utility model, a fixing pad is glued and fixedly installed on the inner surface of the fixing ring, and a positioning pin is spirally inserted and installed on the upper surface of the universal ball seat.

[0012] As a further improvement of this utility model, guide seats are fixedly installed at both the front and rear ends of the inner surface of the support frame.

[0013] As a further improvement of this utility model, a locking ring is glued and fixedly installed on the inner surface of the locking wheel.

[0014] The beneficial effects of this utility model are:

[0015] This invention facilitates the adjustment and control of yarn tension during conveying, thereby reducing uneven tension and density in sewing thread production and improving the quality of yarn conveying. It also helps to manage the continuous conveying of yarn, restricting the yarn's path and preventing tangling due to tension differences, thus avoiding the reduction in sewing thread weaving quality caused by continuous conveying.

[0027] Please see Figures 1-5 As shown, a yarn feeding structure for sewing thread production includes a support frame 1. The lower surface of the support frame 1 is provided with several limiting slots 101. A shaft 2 is inserted and installed through the upper part of the outer surface of the support frame 1 on the side that is close to each other. Both ends of the shaft 2 extend outward through the support frame 1. Locking screw rings 201 are spirally sleeved and fixedly installed on the outer surface of both ends of the shaft 2.

[0028] A number of fixing rings 3 are evenly fitted and fixed on the outer surface of the shaft 2. Fixing pads 301 are glued and fixed on the inner surface of the fixing rings 3. Universal ball seats 302 are fixedly installed at the middle of the front and rear ends of the outer surface of the fixing rings 3. A positioning pin 303 is spirally inserted into the upper surface of the universal ball seat 302. A fixing rod 304 is fixedly installed at the middle of the lower surface of the fixing rings 3.

[0029] A universal ball 4 is movably embedded in the inner surface of the universal ball seat 302. A connecting rod 401 is fixedly provided in the middle of the outer surface of the universal ball 4 away from the universal ball seat 302. A support frame 402 is fixedly provided at the other end of the connecting rod 401. Guide seats 403 are fixedly installed at both the front and rear ends of the inner surface of the support frame 402. A locking wheel 5 is fixedly installed on the outer surface of the fixing rod 304.

[0030] A locking ring 501 is glued and fixedly installed on the inner surface of the locking wheel 5. A guide wheel 502 is movably sleeved in the middle of the outer surface of the locking wheel 5. Positioning holes 503 are opened through the middle of the four sides of the upper and lower surfaces of the locking wheel 5. A sleeve 6 is movably inserted into one side of the outer surface of the locking wheel 5.

[0031] Positioning rods 601 are movably inserted into the upper and lower parts of the inner surface of the sleeve 6. Positioning blocks 602 are fixedly installed at the far ends of the positioning rods 601. The positioning blocks 602 are embedded in the positioning holes 503. A first compression spring 603 is movably sleeved in the middle of the outer surface of the positioning rods 601. One end of the first compression spring 603 is connected to the outer surface of the positioning block 602, and the other end of the first compression spring 603 is connected to the outer surface of the sleeve 6. A second compression spring 604 is fixedly installed at the close ends of the positioning rods 601. A limit wheel 605 is movably sleeved on the outer surface of the sleeve 6.

[0032] In use, one end of the yarn can be passed through the first support frame 402 and the yarn can be attached to the outer surface of the guide wheel 502. At this time, the yarn can be pulled through the second support frame 402 and connected to the sewing thread weaving device. In this case, the yarn conveying tension will be provided by the support frame 402. Then, the positioning pin 303 can be loosened and the universal ball 4 can be controlled to rotate in the universal ball seat 302, thereby adjusting the support angle of the connecting rod 401. By adjusting the support angle of the connecting rod 401, the support angle of the support frame 402 can be adjusted. By changing the support angle of the two sets of support frames 402, the yarn support tension can be adjusted. After the yarn conveying tension is adjusted, the positioning pin 303 can be tightened again to lock and fix the universal ball 4, thereby ensuring the stability of the support frame 402 in supporting the yarn tension.

[0033] Once the yarn conveying tension is adjusted, the positioning block 602 can be squeezed, thereby controlling the positioning rod 601 to retract toward the inside of the sleeve 6. During the retraction of the positioning rod 601, the first compression spring 603 and the second compression spring 604 can be compressed simultaneously. At this time, the positioning block 602 can be locked into the locking wheel 5 and aligned with the positioning hole 503. The compression on the positioning block 602 can be released, thereby releasing the pressure of the first compression spring 603 and the second compression spring 604. At this time, the first compression spring 603 and the second compression spring 604 can begin to rebound, causing the positioning rod 601 to extend toward the outside of the sleeve 6. The extension of the positioning rod 601 pushes the positioning block 602 into the positioning hole 503. At this time, the sleeve 6 can be installed and connected with the locking wheel 5. At the same time, the limiting wheel 605 sleeved on the outer surface of the sleeve 6 will work together with the guide wheel 502 to complete the guiding and clamping of the yarn.

[0034] After the sleeve 6 and the locking wheel 5 are installed and connected, the limiting wheel 605 will contact the guide wheel 502. At the same time, the limiting wheel 605 and the guide wheel 502 are in an active state, which can roll and guide the yarn during the conveying process. While ensuring the normal conveying of the yarn, the gap between the limiting wheel 605 and the guide wheel 502 can be used to restrict the conveying path of the yarn. When the yarn gets tangled during the conveying process, the tangled part will exceed the range of the passage. At this time, the tangled part can be restricted by the limiting wheel 605 and the guide wheel 502. The production personnel can quickly correct the tangled part to avoid the continuous conveying of the tangled part from affecting the weaving quality of the sewing thread.

[0035] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
