Description

Technical Field

[0001] This utility model relates to the field of yarn separation technology, specifically to a yarn separation device for preventing the breakage of mixed yarns. Background Technology

[0002] Blending and separating yarns is a crucial process in textile processing. Its function is to combine and separate yarns of different materials, colors, or properties to provide blended yarns that meet the requirements for subsequent weaving, knitting, and other processes. In this process, the control of yarn tension is of paramount importance: too little tension will cause the yarn to loosen and become tangled, resulting in yarn breakage and product quality defects; too much tension will directly cause the yarn to be overstretched or even break, which will also affect the continuity of production and the quality of finished products.

[0003] Referring to the patent document: Patent Publication No. CN223033550U, Patent Publication Date 2525-06-27, it includes a base, a yarn divider, and at least one yarn divider roller. The yarn divider is disposed on the base and includes a frame defining a region, and a plurality of spacers disposed on the frame. The spacers divide the region into a plurality of slits. The slits are used for a plurality of yarns to pass through at intervals. The at least one yarn divider roller is disposed on the base and located downstream of the yarn divider along the yarn transport direction. The at least one yarn divider roller includes a rotatable roller body. The roller body has an outer peripheral surface and a plurality of annular grooves formed on the outer peripheral surface for the yarns to be spaced out. By separating the yarns through the slits of the yarn divider, the yarns can be prevented from crossing or overlapping. By using the yarn-splitting roller to transport the yarn, wear caused by friction between the yarn and the yarn-splitting roller can be avoided, thus preventing problems such as fuzzing or yarn breakage.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Traditional yarn mixing and separating equipment often lacks precise control over yarn tension, employing rigid tensioning or elastic pressure structures. When the yarn experiences sudden changes in tension, it cannot adapt and adjust in time, leading to excessive tension and breakage, or excessive relaxation causing tangling and disorder. This not only affects the quality of yarn processing but also reduces production efficiency due to frequent production interruptions.

[0006] Therefore, this utility model provides a yarn mixing and separating device to prevent the mixed yarn from breaking. Utility Model Content

[0007] To address the problem that traditional yarn mixing and separating equipment often suffers from breakage or tangling due to insufficient rigidity of the tensioning structure and lack of effective adaptive adjustment, which can lead to sudden changes in yarn tension, the purpose of this invention is to provide a yarn mixing and separating device that prevents the breakage of mixed yarns.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a yarn mixing and separating device to prevent the breakage of mixed yarns, comprising a base, wherein an adjustment mechanism is provided on the upper part of the base for adjusting the tension of the yarns, the adjustment mechanism comprising:

[0009] The tensioning assembly includes a movable frame that is slidably mounted on the upper part of the base. Each movable frame has an inlet guide groove on one side of its upper part.

Each pair of adjusting frames has a drive rod that is movably mounted on its upper part. The other end of each pair of drive rods is movably mounted on the upper part of the outer shell. Each sliding frame has a spring that is fixedly mounted on the middle of its top. The other end of each spring is fixedly mounted on the middle of the outer shell. Each outer shell has a fixed frame that is fixedly mounted on the middle of its top. Each fixed frame has an outlet guide groove on one side of its middle.

[0010] The telescopic assembly, located in the middle of the base, is used to adjust the spacing of multiple sets of adjustment frames.

[0011] Preferably, the telescopic component includes a guide block that is slidably engaged inside the base, a fixing block that is fixedly installed in the middle of the base, and the top ends of the fixing block and the guide block that are fixedly installed in the bottom of the corresponding movable frame. Two symmetrically distributed drive linkages are rotatably installed in the bottom ends of the two guide blocks, and two symmetrically distributed transmission linkages are rotatably installed in the middle of the bottom ends of the other guide blocks and the fixing block.

[0016] Beneficial effects

[0017] This invention provides a yarn separating device to prevent the breakage of mixed yarns. Compared with the prior art, it has the following advantages:

[0018] 1. This application utilizes a method where the yarn passes through the limiting rollers on the left and right sets of adjusting frames in an S-shaped path to form flexible contact. Under the continuous tension of the spring, the sliding frame drives the adjusting frame to always tend to open outward, thereby applying a constant and moderate tension to the yarn. When the yarn tension changes abruptly, it can adaptively adjust. When the tension increases, the spring compresses and the adjusting frame closes to relieve the tension; when the tension decreases, the spring extends and the adjusting frame opens to prevent slack. Thus, through dynamic adjustment, the yarn is always kept in the optimal tension state, significantly reducing the yarn breakage rate and production interruption frequency, and improving processing stability and yarn quality.

[0019] 2. This application uses a cylinder to drive the guide blocks, and the drive linkage and transmission linkage work together to drive each guide block to synchronously and equidistantly expand or contract the tensioning components on the upper part, thereby quickly adjusting the lateral spacing between the limit roller groups. This allows the equipment to quickly adapt to the processing needs of different types, ply numbers or specifications of yarn without the need for manual adjustment, significantly reducing downtime for yarn changeover and improving the equipment's versatility and production flexibility.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a yarn mixing and separating device to prevent the breakage of mixed yarns, including a base 1, and an adjustment mechanism 2 on the upper part of the base 1 for adjusting the tension of the yarns. The adjustment mechanism 2 includes:

[0028] The tensioning assembly 21 includes movable frames 212 slidably mounted on the upper part of the base 1. Each movable frame 212 has an inlet guide groove 2121 on one side of its upper part. Each movable frame 212 has a support frame 211 fixedly mounted at its top. Each support frame 211 has a housing 213 fixedly mounted at its top. Each housing 213 has a sliding frame 215 slidably mounted on its lower part. Each sliding frame 215 has an adjusting frame 216 rotatably mounted at the middle of both ends. Each pair of adjusting frames 216 has a plurality of equally spaced limiting rollers 217 rotatably mounted on one side. During installation, the yarn passes over the limiting rollers 217 in an S-shape, moving left and right sequentially. Each pair of adjusting frames 216 has a drive rod 218 movably mounted on its upper part. The other end of each pair of drive rods 218 is movably mounted on the upper part of the housing 213. Each sliding frame 215 has a spring fixedly mounted at the middle of its top. 219, the other ends of multiple springs 219 are fixedly installed in the middle of the outer shell 213, and a fixing frame 214 is fixedly installed in the middle of the top of multiple outer shells 213. An outlet guide groove 2141 is opened in the middle of one side of multiple fixing frames 214. When conveying yarn, the yarn first passes through the lower inlet guide groove 2121 upward and then passes through the left and right corresponding limit rollers 217 in sequence, and finally exits from the upper outlet guide groove 2141, so that it is connected to the yarn processing equipment. During the conveying process, under the force between the yarn and the limit rollers 217, and through the tension of the springs 219, the lower part of the two adjusting frames 216 can always be opened outward, so as to ensure that the yarn is always in a taut state during the conveying process. Under the self-adaptation of the springs 219, the yarn can be prevented from being over-tightened or loosened, thus preventing it from being broken.

[0029] The telescopic component 22 is located in the middle of the base 1 and is used to adjust the spacing of multiple sets of adjustment brackets 216.

[0030] The telescopic component 22 includes a guide block 222 that is slidably engaged inside the base 1. A fixed block 2221 is fixedly installed in the middle of the base 1. The top ends of the fixed block 2221 and the guide block 222 are both fixedly installed at the bottom of the corresponding movable frame 212. Two symmetrically distributed drive rods 224 are rotatably installed at the bottom ends of two guide blocks 222 and the fixed block 2221. Two symmetrically distributed transmission rods 223 are rotatably installed at the middle of the bottom ends of several other guide blocks 222 and the fixed block 2221. The multiple transmission rods 223 are interconnected and cooperate with each other. One end of two sets of transmission rods 223 is movably installed at the end of the drive rod 224. A drive component is provided on one side of the base 1. By driving one of the guide blocks 222 to move, the guide blocks 222 located on both sides of the fixed block 2221 can be moved synchronously and at equal intervals to both sides under the cooperation of the drive rod 224 and the transmission rod 223. This allows the spacing of the tensioning component 21, which guides and adjusts the tension of the yarn, to be adjusted.

[0031] The drive assembly includes a cylinder 225 fixedly mounted on one side of the base 1. The drive end of the cylinder 225 is fixedly mounted on the middle of one side of one of the guide blocks 222. The cylinder 225 is an SMC standard cylinder model JMDBB32-50-M9BW. The drive end of the cylinder 225 is fixedly mounted on the upper part of one of the guide blocks 222. Under its drive, the spacing of the tensioning assembly 21 can be adjusted through the cooperation of the transmission link 223 and the drive link 224.

[0032] Telescopic rods 2191 are fixedly installed in the middle of the multiple outer shells 213. The other end of the multiple telescopic rods 2191 is fixedly installed in the middle of one side of the sliding frame 215. The telescopic rods 2191 can guide and stabilize the sliding block 215, ensuring that the two adjusting frames 216 can stably limit the yarn.

[0033] A guide rod 221 is fixedly installed in the middle of the base 1. The guide rod 221 slides through the middle of the guide block 222 and the fixed block 2221. The guide rod 221 can support and guide the guide block 222 and the fixed block 2221, so that they can slide stably along the guide rod 221 under the drive of the cylinder 225.

[0034] Both ends of the base 1 are fixedly installed with mounting bases 11. Multiple mounting holes are opened in the middle of the two mounting bases 11. By opening multiple mounting holes on the upper part of the mounting base 11, it can be used with bolts to allow the bolts to pass through the mounting holes and be installed on the yarn processing equipment.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, the mixed yarn to be processed first enters the inlet guide groove 2121 from below, then passes laterally along an S-shaped path around multiple limiting rollers 217 distributed on the left and right sets of adjusting frames 216, and finally exits from the upper outlet guide groove 2141 and is connected to the subsequent yarn processing equipment. During the yarn conveying process, the tension of the spring 219 exerts a force on the sliding frame 215, which is transmitted to the adjusting frame 216 and finally to the limiting rollers 217, so that the lower part of the left and right adjusting frames 216 is always subjected to an outward opening tendency. The force of the spring 219 is balanced with the yarn tension, forming an adaptive adjustment. When the yarn tension increases, the spring 219 is compressed, and the adjusting frame is slightly tightened to relieve excessive tension; when the yarn tension decreases, the spring 210 extends, pushing the adjusting frame to open, preventing the yarn from slack, and effectively avoiding breakage due to excessive tension or disorder due to excessive relaxation.

[0037] When different types, ply counts, or specifications of yarn need to be processed, the spacing of multiple tensioning units can be adjusted to activate cylinder 225. Its drive end pushes or pulls the guide block 222 connected to it to move. The movement of the guide block 222 is transmitted to other guide blocks 222 and fixed blocks 2221 through a linkage mechanism composed of drive linkage 224 and transmission linkage 223 hinged to it. Since the linkages are hinged to each other and symmetrically distributed, under the drive of cylinder 225, all guide blocks 222 can move synchronously and equidistantly to both sides or retract towards the center, thereby driving the entire tensioning assembly 21 to move synchronously, thus changing the lateral spacing between each set of limit rollers 217 to adapt to different processing requirements.
