[0002] In the production of lawn fence weaving machines, the yarn feeding equipment is a crucial component that significantly impacts weaving quality and production efficiency. Traditional yarn feeding equipment for lawn fence weaving machines has several shortcomings. For example, yarn tangling and loosening are common during the feeding process, leading to unstable yarn feeding, affecting the continuity and uniformity of weaving, and ultimately reducing product quality. Existing yarn guide structures cannot precisely control the direction and shape of the yarn, making it difficult for the woven fence to meet ideal standards in terms of structural strength and appearance. Furthermore, the lack of an effective monitoring mechanism prevents the timely detection of yarn feeding abnormalities, increasing equipment downtime and labor maintenance costs, thus hindering the efficient and high-quality development of lawn fence weaving production. Therefore, a new type of yarn feeding equipment for lawn fence weaving machines is urgently needed to solve these problems. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. Unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The features mentioned above or in the specific examples mentioned in this invention can be combined arbitrarily, and these specific embodiments are only used to illustrate this invention and are not intended to limit the scope of this invention.

[0018] Example

[0019] like Figure 1 As shown, this utility model provides a yarn feeding device for a lawn fence weaving machine, including a yarn feeding mechanism 1, a yarn guiding mechanism 2, and a monitoring mechanism 3. The yarn feeding mechanism 1 has a yarn feeding frame 4 with a yarn feeding wheel 11 on one side and a first yarn guiding assembly of the yarn guiding mechanism 2 on the other side. The second shaping assembly of the yarn guiding mechanism 2 is connected to the weaving machine body 5. A tensioning wheel 23 is provided between the first yarn guiding wheel 21 and the second yarn guiding wheel 22 of the first yarn guiding assembly. The second shaping assembly has several yarn guiding and shaping wheels 24. The limit switch 31 and displacement sensor 32 of the monitoring mechanism 3 are located on the yarn feeding frame 4 at the first yarn guiding assembly.

[0020] A feed roller 11 is installed on one side of the feed frame 4 to hold the raw yarn. On the other side, a first guide assembly and a second shaping assembly are arranged sequentially. The second shaping assembly is connected to the braiding machine body 5 to ensure the yarn can smoothly enter the braiding stage. The first guide roller 21, the second guide roller 22, and the tension roller 23 of the first guide assembly work together to adjust the yarn tension, maintaining a suitable tightness and preventing yarn breakage or tangling caused by slackness or excessive tightness. The guide shaping roller 24 on the second shaping assembly shapes the yarn, ensuring it enters the braiding machine body 5 in a regular shape. The position and operating status of the tension roller 23 can be monitored in real time by the limit switch 31 and displacement sensor 32 installed on the feed frame 4 at the first guide assembly, and the operating status of the feed motor 12 can be adjusted accordingly.

[0021] The second guide wheel 22 and the first guide wheel 21 have the same structure. A limit adjustment frame 25 is provided between the first guide wheel 21 and the wire feed frame 4. Limit adjustment grooves 26 are symmetrically provided on both sides of the limit adjustment frame 25. A mounting hole is provided in the center of the limit adjustment frame 25. The first guide wheel 21 passes through the mounting hole and connects to the wire feed frame 4. Limit adjustment blocks 27 are provided in each limit adjustment groove 26.

[0022] The wire passes between the limiting adjustment block 27 and the first guide wheel 21. The position of the limiting adjustment block 27 within the limiting adjustment groove 26 is adjusted according to the diameter and movement path of the wire to ensure smooth wire feeding. The limiting adjustment groove 26 is symmetrically arranged relative to the mounting hole to ensure that the adjustment distance of the limiting adjustment block 27 is the same on both sides of the first guide wheel 21.

[0023] like Figure 2As shown, a trumpet-shaped feed tube 13 is provided between the first guide roller 21 and the feed roller 11. The feed tube 13 is connected to the top of the feed frame 4, and the top of the feed tube 13 is provided with a feed hole. The trumpet-shaped structure of the feed tube 13 can play a preliminary guiding and gathering role for the yarn, so that the yarn can enter the first guide roller 21 more smoothly from the feed roller 11, reduce the deviation and scattering of the yarn in the initial stage of feeding, and improve the stability and efficiency of feeding.

[0024] like Figure 3 As shown, a counterweight 28 is connected to the front side of the tensioning wheel 23, and the slider on the rear side of the tensioning wheel 23 is slidably connected to the slide rail 29 on the wire feed frame 4. A limit adjustment frame 25 is provided between the tensioning wheel 23 and the slider, and a limit switch 31 and a displacement sensor 32 are located on both sides of the slide rail 29, respectively.

[0025] The distance between the upper limit adjustment block 27 and the tensioning wheel 23 on the limit adjustment frame 25 is adjusted to ensure smooth thread feeding. The counterweight 28 utilizes gravity to apply a stable tension to the thread using the tensioning wheel 23. When the thread tension changes, the tensioning wheel 23 can slide on the slide rail 29 for adaptive adjustment. As the tensioning wheel 23 moves upward along the slide rail 29, the displacement sensor 32 monitors the position of the tensioning wheel 23 and adjusts the thread feeding speed of the thread feeding motor 12 accordingly. When the tensioning wheel 23 contacts the limit switch 31, it stops moving upward.

[0026] The guide yarn shaping wheel 24 is hinged to the guide yarn shaping frame, which is connected to the braiding machine body 5. The position of the guide yarn shaping frame allows the yarn after passing through the guide yarn shaping wheel 24 to directly enter the braiding machine body 5 for weaving.

[0027] The feeding motor 12 connected to the feeding roller 11 is located behind the feeding frame 4. The feeding motor 12 can precisely control the rotation speed and feeding amount of the feeding roller 11, and works in coordination with the feeding mechanism 1 and the guiding mechanism 2 to ensure a stable supply of yarn and provide power support for the smooth operation of the entire feeding process.

[0028] During operation, the unloading motor 12 drives the unloading wheel 11 to rotate, and the yarn is released from the unloading wheel 11 and guided into the first guide assembly by the trumpet-shaped feed tube 13. The first guide wheel 21, the second guide wheel 22, and the tension wheel 23 in the first guide assembly provide initial guidance and tension adjustment for the yarn. Under the action of the counterweight 28 and the slide rail 29, the tension wheel 23 automatically adjusts its position according to the yarn tension to maintain a suitable tension. The yarn processed by the first guide assembly enters the second shaping assembly, where the guide shaping wheel 24 shapes the yarn. After passing through the guide shaping wheel 24, the yarn directly enters the braiding machine body 5 for weaving. Throughout the entire yarn feeding process, the limit switch 31 and the displacement sensor 32 on the feed frame 4 at the first guide assembly monitor the position of the yarn and the state of the tension wheel 23 in real time.

[0029] Therefore, the feeding device of the lawn fence weaving machine with the above-mentioned structure of this utility model has a stable feeding process, which can ensure that the yarn enters the main body of the weaving machine with appropriate tension and shape, thereby improving the weaving quality and production efficiency.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
