Description

Technical Field

[0001] This utility model relates to the field of fabric yarn guiding technology, specifically to a dynamic tension-adjustable anti-snagging warp-knitted fabric yarn guiding device. Background Technology

[0002] In the production process of warp-knitted fabrics, the yarn guiding device is one of the key pieces of equipment. Its performance directly affects the quality of yarn delivery, knitting efficiency, and the final fabric quality. Traditional yarn guiding devices often suffer from problems such as unstable yarn tension, internal stress, or static electricity accumulation during operation, which can lead to yarn snagging, breakage, and tangling during knitting. This seriously affects the appearance and quality of the fabric, especially for high-count, high-density, or elastic yarns, which are more sensitive to tension. Traditional fixed or mechanically adjustable tension control cannot achieve real-time, dynamic, and precise adjustment, which can easily cause tension fluctuations and lead to weaving defects. Therefore, it is particularly important to improve existing yarn guiding devices and design a new type of dynamic tension-adjustable anti-snagging warp-knitted fabric yarn guiding device to solve the above-mentioned technical defects and improve the overall practicality of the yarn guiding device. Utility Model Content

[0003] The purpose of this invention is to provide a dynamic tension-adjustable anti-snagging warp-knitted fabric yarn guiding device, which solves the problem that traditional yarn guiding devices often cause yarn snagging, breakage, and twisting during knitting due to unstable yarn tension, internal stress, or static electricity accumulation, which seriously affects the appearance and quality of the fabric.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A dynamic tension-adjustable anti-snagging warp-knitted fabric yarn guiding device includes a workbench body, a connecting frame fixedly connected to the top of the workbench body, a heating component inside the connecting frame, and a tension component inside the connecting frame and located inside the heating component.

[0006] The heating assembly is used to iron the yarn. The heating assembly includes two sets of guide rollers rotatably connected to both ends inside the connecting frame. Multiple sets of first guide grooves are opened on the outer side of the guide rollers. The heating assembly also includes two sets of connecting pipes fixedly connected to both sides of the connecting frame. Multiple sets of water supply pipes are fixedly connected to the end of the connecting pipes near the connecting frame.

[0007] The tension assembly is used to adjust the tension of the yarn.

[0008] As a preferred embodiment of this utility model, multiple sets of the first guide grooves are distributed at equal intervals on the outer side of the guide roller, and the inside of the guide roller is designed with a hollow structure.

[0009] As a preferred embodiment of this utility model, the end of the water supply pipe away from the connecting pipe is fixedly connected to the connecting frame, the water supply pipe is rotatably connected to the guide roller, and the two sets of opposite water supply pipes are interconnected through the guide roller.

[0010] As a preferred embodiment of this utility model, a heating box is fixedly connected inside the main body of the workbench, and both sets of connecting pipes extend into the interior of the main body of the workbench and are connected to the heating box. A water pump is fixedly connected to the outside of one set of connecting pipes and located inside the main body of the workbench, and the water pump is connected to the heating box.

[0011] As a preferred embodiment of this utility model, both ends of the connecting frame are fixedly connected to connecting plates, and multiple sets of second guide grooves are formed inside the connecting plates.

[0012] As a preferred embodiment of the present invention, the tension assembly includes a connecting rod fixedly connected to the middle of the connecting frame and located between multiple sets of guide rollers, a connecting frame is provided below the connecting rod, and a tension roller is rotatably connected to the bottom of the connecting frame. The tension assembly also includes a rotating roller rotatably connected to the inside of the connecting frame and located below the tension roller.

[0013] As a preferred embodiment of this utility model, a sliding rod is fixedly connected to the bottom of the connecting rod, and sliding blocks are slidably connected to both ends of the sliding rod. A rotating rod is rotatably connected to the bottom of the sliding block, and the bottom of the rotating rod is rotatably connected to the connecting frame. Compression springs are sleeved on both ends of the sliding rod and on the outside of the two sets of sliding blocks.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the heating component is designed to iron the yarn online during the yarn guiding process, eliminating internal stress and preventing bending and twisting, thus fundamentally preventing snagging. Ironing eliminates internal curl stress and static electricity in the yarn, making it straight and smooth. This greatly reduces the probability of the yarn getting caught on the knitting needles due to yarn fuzz and twisting during subsequent knitting, significantly improving the quality and yield of warp-knitted fabrics. Integrating the ironing process into the yarn guiding path achieves synchronous processing during production, eliminating the need for additional offline ironing equipment and steps, simplifying the process, and improving overall production efficiency. The closed-loop thermal circulation system ensures the uniformity and stability of the guide roller surface temperature, avoiding inconsistent yarn treatment effects or yarn burns caused by temperature fluctuations, ensuring reliable processing quality. The guide roller has both guiding and heating functions, with a compact structure, ingenious design, and high space utilization.

[0016] 2. In this utility model, the tension component is designed to sense and automatically adjust the yarn tension in real time, ensuring that the yarn maintains a stable and appropriate tension during the weaving process. The dynamic self-adjustment function can effectively absorb and compensate for tension fluctuations caused by irregular yarn bobbins, mechanical vibrations, or slight speed changes, ensuring that the tension of each yarn fed into the weaving area is uniform. This is the key to producing high-quality, flawless, and smooth warp-knitted fabrics, preventing accidental yarn breakage due to excessive tension and avoiding yarn slack, accumulation, and defects caused by insufficient tension, thus ensuring the continuity and stability of production.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A dynamic tension-adjustable anti-snagging warp-knitted fabric yarn guiding device includes a workbench body 1, a connecting frame 2 fixedly connected to the top of the workbench body 1, a heating component 3 provided inside the connecting frame 2, and a tension component 4 provided inside the connecting frame 2 and inside the heating component 3.

[0026] The heating component 3 is used to iron the yarn. The heating component 3 includes two sets of guide rollers 5 rotatably connected to both ends inside the connecting frame 2. Multiple sets of first guide grooves 6 are opened on the outer side of the guide rollers 5. The heating component 3 also includes two sets of connecting pipes 7 fixedly connected to both sides of the connecting frame 2. Multiple sets of water supply pipes 8 are fixedly connected to one end of the connecting pipes 7 near the connecting frame 2.

[0027] Tension assembly 4 is used to adjust the tension of the yarn.

[0028] Furthermore, multiple sets of first guide grooves 6 are evenly distributed on the outer side of the guide roller 5, and the inside of the guide roller 5 is designed with a hollow structure. When multiple sets of yarns come into contact with the guide roller 5, the multiple sets of first guide grooves 6 can guide the multiple sets of yarns, so that the yarns can move stably.

[0029] The end of the water supply pipe 8 away from the connecting pipe 7 is fixedly connected to the connecting frame 2. The water supply pipe 8 is rotatably connected to the guide roller 5. The two sets of opposite water supply pipes 8 are interconnected through the guide roller 5. A heating box 9 is fixedly connected inside the main body 1 of the workbench. Both sets of connecting pipes 7 extend into the main body 1 of the workbench and connect to the heating box 9. A water pump 10 is fixedly connected to the outside of one set of connecting pipes 7 and inside the main body 1 of the workbench. The water pump 10 is connected to the heating box 9. When the yarn is introduced into the interior of the connecting frame 2, the water pump 10 is started to introduce the hot water inside the heating box 9 into the interior of one set of connecting pipes 7, so that the hot water can be introduced into the interior of multiple sets of water supply pipes 8, and into the interior of multiple sets of guide rollers 5. The guide rollers 5 can iron the yarn to prevent the bent yarn from becoming crooked and avoid the situation of being difficult to sort. The hot water is introduced into the interior of another set of connecting pipes 7 through another set of water supply pipes 8, and then reintroduced into the interior of the heating box 9 for heating treatment again to maintain the temperature.

[0030] Secondly, both ends of the connecting frame 2 are fixedly connected to connecting plates 11. Multiple sets of second guide grooves 12 are opened inside the connecting plates 11. When multiple sets of yarns are introduced into the interior of the connecting frame 2, the multiple sets of second guide grooves 12 can guide the multiple sets of yarns, so that the yarns come into contact with the first guide grooves 6 on the guide rollers 5, and the yarns come into contact with the two sets of guide rollers 5 in an "S" shape, so that the guide rollers 5 can iron the yarns.

[0031] Furthermore, the tension assembly 4 includes a connecting rod 13 fixedly connected to the middle of the connecting frame 2 and located between multiple sets of guide rollers 5. A connecting frame 14 is provided below the connecting rod 13. A tension roller 15 is rotatably connected to the bottom of the connecting frame 14. The tension assembly 4 also includes a rotating roller 16 rotatably connected to the inside of the connecting frame 2 and located below the tension roller 15. A sliding rod 17 is fixedly connected to the bottom of the connecting rod 13. Sliding blocks 18 are slidably connected to both ends of the sliding rod 17. A rotating rod 19 is rotatably connected to the bottom of the sliding blocks 18. The bottom of the rotating rod 19 is rotatably connected to the connecting frame 14. Compression springs 20 are sleeved on both ends of the sliding rod 17 and on the outside of the two sets of sliding blocks 18. When the yarn is introduced into the inside of the connecting frame 2, the compression springs 20 drive the sliding blocks 18 to move, causing the rotating rod 19 to move, which in turn drives the connecting frame 14 to move downward, bringing the tension roller 15 into contact with the yarn. In conjunction with the rotating roller 16, the tension of the yarn can be adjusted and the yarn tightened.

[0032] In this embodiment, the specific implementation scenario is as follows: when multiple sets of yarns are introduced into the connecting frame 2, multiple sets of second guide grooves 12 can guide the multiple sets of yarns, making the yarns contact with the first guide grooves 6 on the guide rollers 5, and making the yarns contact the two sets of guide rollers 5 in an "S" shape. The water pump 10 is started to introduce hot water from the heating box 9 into the interior of a set of connecting pipes 7, so that the hot water is introduced into the interior of multiple sets of water supply pipes 8, and so that the hot water can be introduced into the interior of multiple sets of guide rollers 5. The guide rollers 5 can iron the yarns to prevent the bent yarns from becoming crooked. To prevent situations from becoming difficult to manage, hot water is introduced into another set of connecting pipes 7 through another set of water supply pipes 8, and then reintroduced into the heating box 9 for reheating and temperature maintenance. The compression spring 20 drives the sliding block 18 to move, causing the rotating rod 19 to move, which in turn drives the connecting frame 14 to move downward, bringing the tension roller 15 into contact with the yarn. In conjunction with the rotating roller 16, the tension of the yarn can be adjusted and tightened. Compared with existing yarn guiding devices, this utility model improves the overall practicality of the yarn guiding device through its design.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
