Description

Technical Field

[0001] This utility model relates to the technical field of ribbon processing equipment, and in particular to a thread feeding and splitting device for a special ribbon weaving machine for cigarette machines. Background Technology

[0002] In the production process of ribbon looms, especially high-speed narrow-width ribbon looms, the yarn feeding device (usually called yarn frame or bobbin frame) is a key upstream equipment. Its core function is to carry a large number of yarn bobbins (or tubes) and transport hundreds or thousands of warp yarns to the main body of the ribbon loom for weaving in an orderly, stable and uniform tension manner. The control of warp tension is a crucial parameter in the entire weaving process, which directly affects production efficiency and the quality of the final fabric.

[0003] Traditional yarn feeding devices in the prior art, especially in large-scale production, have uneven yarn tension that is difficult to control. Traditional yarn racks usually occupy a large area, have a dispersed structure, and have yarn bobbins arranged on multiple layers.

[0004] Because of the different physical positions of the yarn bobbins and the loom inlet, the path length and turning angle of each yarn are also different. This inherent geometric difference results in inconsistent tension in each yarn from the very beginning. Some yarns are too tight, while others are too loose. Uneven tension can cause a series of serious problems, such as unclear shedding, making it difficult to introduce the weft yarn; too low tension will cause the yarns to slack and tangle, while too high tension will overstretch the yarns and even cause them to break under friction and dynamic loads.

[0005] Ultimately, these problems will manifest in the finished webbing, resulting in defects such as uneven thickness, wrinkles, skipped stitches, and broken warp threads, which seriously affect product quality, especially when producing products such as suction ribbons that require extremely high uniformity. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a yarn feeding and splitting device for a special weaving machine for cigarette machine suction ribbons, which solves the problems of uneven yarn tension, easy tangling and knotting, and low space utilization caused by the unreasonable structure of the yarn feeding device in the prior art.

[0007] To achieve the above and other related objectives, this utility model provides a yarn feeding and splitting device for a special weaving machine for cigarette machine suction ribbons. The device includes a frame, multiple feed racks mounted on the frame for placing yarn bobbins, a yarn feeding assembly mounted on the frame for splitting and feeding yarn, and a yarn guide mounted on the upper part of the frame corresponding to the yarn bobbins and feeding the yarn to the yarn feeding assembly. The feed racks include two relatively inclined plates and multiple placement rods evenly arranged on the plates for yarn bobbin fitting. The number of yarn guides corresponds to the number of placement rods and is arranged on the upper side of the frame. A conveying assembly capable of moving the yarn is also provided on the outer side of the frame.

[0008] By adopting the above technical solution, the functions of yarn bobbin placement, preliminary guidance, yarn sorting and separation, and active conveying are integrated into a compact frame, so that the entire path of the yarn from the bobbin to the output end is under control, with a clear path and orderly process. This fundamentally avoids the problems of yarn crossing and tangling caused by the chaotic layout of traditional distributed yarn racks. At the same time, the vertical structural layout significantly improves space utilization and reduces the equipment footprint.

[0009] In one embodiment of this utility model, the two material plates are arranged in an inverted V shape, and the placement rod is set perpendicular to the surface of the material plates so that the yarn bobbin is tilted upwards after placement.

[0010] By adopting the above technical solution, the two material plates are arranged in an inverted V shape, which can accommodate more yarn bobbins in a limited horizontal width. The placement rod is set perpendicular to the inclined material plate surface, so that the yarn bobbin is tilted upward after being sleeved. Gravity helps to fix the yarn bobbin stably on the placement rod, preventing it from shaking or falling off during high-speed unwinding. At the same time, it also allows the yarn to be smoothly drawn out from the top of the yarn bobbin, reducing unwinding resistance.

[0011] In one embodiment of the present invention, a support plate for installing cable guides is provided at the upper end of the frame. The cable guides are vertically installed on the upper surface of the support plate, and each support plate is inclined upward on the frame. Multiple cable guides can be arranged horizontally on each support plate.

[0012] By adopting the above technical solution and installing the yarn guide by setting up multiple independent, upward-sloping support plates, layered management of different yarn rows is achieved. Each yarn row has its own dedicated guiding layer, which effectively avoids interference and tangling between upper and lower yarn layers due to slack and drooping, ensuring the independence and clarity of each yarn path. This is crucial for preventing mutual wear and knotting between yarns.

[0013] In one embodiment of the present invention, the cable assembly includes a guide rod disposed above a support plate and a plurality of cable dividers disposed behind the guide rod for the yarn to pass through. The guide rod is disposed along the length direction of the support plate, and the cable dividers are evenly arranged along the axial direction of the guide rod.

[0014] By adopting the above technical solution, after the yarn passes through the threading hole of the yarn separator, it is forced to arrange into a yarn array with uniform spacing and parallel to each other, which ensures that a clear and clean opening can be formed in the subsequent weaving process. This has a direct effect on improving fabric quality and reducing weaving defects.

[0015] In one embodiment of this utility model, the wire separator is provided with a plurality of threading holes for yarn to pass through, evenly arranged along the axis of the guide rod.

[0016] In one embodiment of the present invention, a gap is provided between adjacent support plates, the gap is connected to the material feeding rack below the frame, and the yarn on the yarn bobbin of the material feeding rack can pass through the gap and connect to the yarn guide.

[0017] By adopting the above technical solution, the gap between adjacent support plates provides a straight and unobstructed upward channel for the yarn on the lower feed rack. The yarn can directly pass through this gap to reach the upper yarn guide, avoiding the additional bending and friction points caused by the yarn having to go around the crossbeam or other structural components in the traditional design. This reduces unnecessary contact and friction, thereby reducing the risk of yarn tension fluctuation and fiber damage, helping to maintain stable yarn tension and reduce yarn breakage rate.

[0018] In one embodiment of the present invention, the cable assembly is disposed on one side of the end support plate, and the tilt angle of each support plate connected to the upper side of the frame increases sequentially from far to near according to the distance from the cable assembly.

[0019] By adopting the above technical solution, the horizontal travel distance of the yarn that is farther away from the yarn guide assembly is longer. In order to keep the total path length consistent with that of the yarn that is closer, the design increases the vertical travel distance of the yarn by increasing the tilt angle of the support plate at a distance. By precisely designing the angle of each support plate, the total yarn path length from any yarn bobbin, through its corresponding yarn guide, to the yarn guide assembly can be made to be approximately equal.

[0020] In one embodiment of the present invention, the conveying assembly includes a receiving wheel disposed on the upper side of the guide rod capable of receiving yarn and a conveying roller group disposed on the lower side of the receiving wheel.

[0021] As described above, the yarn feeding and splitting device for the special weaving machine for cigarette machine suction ribbons of this utility model has the following beneficial effects: it integrates the functions of yarn bobbin placement, preliminary guidance, yarn sorting and splitting, and active conveying into a compact frame, so that the entire path of the yarn from the bobbin to the output end is under control, the path is clear and the process is orderly, which fundamentally avoids the problem of yarn crossing and tangling caused by the chaotic layout of traditional decentralized yarn frames. At the same time, the vertical structural layout significantly improves the space utilization rate and reduces the equipment footprint. Attached Figure Description

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0028] Please see Figures 1 to 2 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0029] Please see Figure 1 and Figure 2This utility model provides a thread feeding and splitting device for a special weaving machine for cigarette machine suction ribbons, including a frame 1 as a support, multiple material racks 2 installed inside the frame 1, a thread feeding assembly 3 and multiple thread guides 4 set at the upper end of the frame 1, and a conveying assembly 6 set on the outside of the frame 1.

[0030] The feed rack 2 is used to carry multiple yarn bobbins 5 as the source of yarn. In this embodiment, each feed rack 2 is composed of two oppositely arranged material plates 20. These two material plates 20 have an inverted V-shaped structure, which can achieve a high-density arrangement of yarn bobbins 5 in a limited space.

[0031] Each material plate 20 has multiple placement rods 21 evenly distributed perpendicular to the plate surface, and the yarn bobbin 5 can be directly sleeved on the placement rods 21. Since the material plate 20 itself is inclined, the yarn bobbin 5 will naturally form an upward tilt angle after being placed, which is conducive to the yarn being unwound and drawn out from the upper end of the yarn bobbin 5.

[0032] At the upper end of the frame 1, there are multiple support plates 22 for mounting the cable guides 4. Each support plate 22 is mounted upward on the frame 1 at a certain angle, and multiple rows of cable guides 4 can be horizontally mounted on its upper surface.

[0033] The yarn guide 4 is usually a ceramic yarn guide eye, which is used to initially guide the yarn and reduce friction. There are preset gaps between adjacent support plates 22. These gaps form a vertical channel from the lower feed rack 2 to the upper yarn guide 4, so that the yarn on each yarn bobbin 5 can pass through the gaps along the shortest and most direct path to reach its corresponding yarn guide 4.

[0034] The tilt angles of the multiple support plates 22 are specially set, and the cable assembly 3 is set on one side of all the support plates 22. The tilt angles of the support plates 22 from the farthest from the cable assembly 3 to the nearest support plate 22 increase sequentially.

[0035] The farthest support plate 22 is tilted at the largest angle, and the thread guide 4 on it is raised to the highest position; while the nearest support plate 22 is tilted at the smallest angle, and the thread guide 4 on it is positioned relatively low. The change in vertical distance is used to compensate for the difference in horizontal distance, so that the total path length from any yarn bobbin 5, through the thread guide 4 at the corresponding height, to the yarn laying assembly 3 is basically the same, thereby achieving passive and structured balance of tension for all yarns.

[0036] After passing through the yarn guide 4, the yarn is gathered to the yarn assembly 3. The yarn assembly 3 includes a guide rod 23 arranged along the length of the support plate 22, and a plurality of yarn distributors 24 evenly arranged on the rear side of the guide rod 23.

[0037] Each yarn distributor 24 has multiple threading holes 25. The yarn first passes over the guide rod 23 and then passes through the threading holes 25 on the yarn distributor 24. After being organized by the yarn laying assembly 3, all the yarns are combed into a bundle of yarn sheets with regular spacing and parallel to each other.

[0038] Finally, the sorted yarn is taken over by the conveying assembly 6. The conveying assembly 6 includes a receiving wheel 26 located above the guide rod 23 and a conveying roller group 27 located below it. The yarn is first received by the receiving wheel 26 and then enters the conveying roller group 27.

[0039] The conveyor roller group 27 is powered and actively pulls the yarn out at a set constant speed and feeds it smoothly into the subsequent weaving machine. This forms a stable yarn feeding process, which effectively buffers and isolates the tension impact generated when the loom is working.

[0040] In summary, this utility model achieves a compact and efficient arrangement of yarn bobbins through an inverted V-shaped feed rack; it cleverly utilizes the geometric structure to compensate for differences in yarn path lengths through the design of an inclined support plate with gaps and variable angles, ensuring the uniformity of tension in each yarn path from the source; and it ensures the regularity of yarn arrangement and the stability of the conveying process through the yarn laying assembly and active conveying assembly.

[0041] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
