Description

Technical Field

[0001] This utility model relates to the technical field of yarn conveying devices, specifically to a yarn conveying frame with adjustable tension. Background Technology

[0002] In the textile industry's production process, yarn conveying is a crucial link, connecting the early stages of yarn spinning and winding with subsequent processing steps such as weaving and knitting. The stability of the conveying process and the appropriateness of the yarn tension directly affect the quality of the final textiles. With the continuous development of textile technology and the increasing market demand for high-quality textiles, increasingly higher requirements are being placed on the yarn conveying process. Traditional yarn conveying methods mostly employ fixed conveyor frames, with yarn relying on simple conveyor rollers for transfer; however, this method has many limitations.

[0003] Different textile processes and different types of yarn have different requirements for tension. Traditional conveyor frames, lacking an effective tension adjustment mechanism, often only use fixed tension settings. This leads to problems during the conveying process: either the yarn is too loose, causing shaking, tangling, and knotting, affecting subsequent processing steps and increasing the defect rate; or it is too tight, causing stretching deformation or even breakage, resulting in raw material waste and production interruption. This severely restricts the efficiency of textile production and the improvement of product quality. Therefore, we propose an adjustable tension yarn conveyor frame to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to provide a yarn conveyor with adjustable tension to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tension-adjustable yarn conveyor frame, comprising a conveyor frame, an adjustment mechanism, a driving wheel, a driven wheel, a mounting base, a conveying roller, and a guide groove. Mounting bases are provided on both sides of the conveyor frame, and a first conveying roller and a second conveying roller are provided between the mounting bases. A driving wheel and a driven wheel are respectively provided on one side of the first conveying roller and the second conveying roller, and the driving wheel and the driven wheel mesh with each other. Guide grooves are opened on both sides of the conveying pipe of the conveyor frame, and guide rollers are provided on the guide grooves. A threaded adjustment mechanism is provided on one side of the conveyor frame.

[0006] Preferably, the adjustment mechanism includes an adjustment frame, a rotating shaft, a connecting piece, an adjustment rod, a limiting groove, a limiting block, a first drive motor, a second drive motor, a threaded rod, a sliding block, a guide rod, and a third drive motor. The adjustment frame is fixedly connected to one side of the conveyor frame, and an adjustment groove is opened inside the adjustment frame. The rotating shaft is movably connected to one side of the conveyor frame and the guide groove. A drive rod is arranged between the rotating shafts. An installation frame is fixedly connected to the adjusting groove. A threaded rod is movably connected between the installation frames. Guide rods are fixedly connected to both sides of the threaded rod on the installation frame. Sliding blocks are sleeved on the guide rods and the threaded rod. The third drive motor is fixedly connected to one side of the installation frame, and the output end of the third drive motor is fixedly connected to the threaded rod.

[0007] Preferably, the sliding block is movably connected to adjusting rods on both sides, and the rotating shaft is fixedly connected to a connecting member in the adjusting groove. The connecting member is movably connected to the adjusting rod, and a limit groove is opened on the rotating shaft. A limit block is fixedly connected to the conveyor frame, and the limit block and the limit groove cooperate with each other.

[0008] Preferably, a first drive motor is fixedly connected inside the adjusting groove, and a first conveying roller is fixedly connected to the output end of the first drive motor. A second drive motor is fixedly connected inside the adjusting groove, and a second conveying roller is fixedly connected to the output end of the second drive motor.

[0009] Preferably, the rotating shaft has a comma-shaped structure, and the protruding end of the rotating shaft cooperates with the guide roller.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Start the third drive motor. Its output end drives the threaded rod to rotate. Due to the threaded transmission relationship between the threaded rod and the sliding block, and the guiding effect of the guide rod on the sliding block, the sliding block will move linearly along the guide rod. The movement of the sliding block is transmitted to the connecting part through the adjusting rod, which in turn drives the rotating shaft to rotate around its axis. Since the rotating shaft has a comma structure, its protruding end cooperates with the guide roller. When the rotating shaft rotates, it will change the relative position of the guide roller. The guide roller may move up or down a certain distance, thereby changing the path length of the yarn between the guide roller and the conveying roller, and realizing the increase or decrease of the yarn tension.

[0012] 2. The first drive motor and the second drive motor can independently control the speed and direction of rotation of the first and second conveying rollers according to actual production needs. For example, when it is necessary to adjust the yarn conveying speed, it can be achieved by changing the output power of the two drive motors. This further improves the control accuracy and flexibility of the conveyor frame over the yarn conveying process, meets the diverse requirements of yarn conveying under different production processes and working conditions, reduces downtime and the frequency of production interruptions, and improves the continuity and overall efficiency of production.

[0019] like Figures 1-4 As shown, the present invention proposes a tension-adjustable yarn conveyor frame, comprising a conveyor frame 1, an adjustment mechanism 2, a driving wheel 3, a driven wheel 4, a mounting base 6, a conveying roller, and a guide groove 8. Mounting bases 6 are provided on both sides of the conveyor frame 1, and a first conveying roller 7 and a second conveying roller 10 are provided between the mounting bases 6. A driving wheel 3 and a driven wheel 4 are respectively provided on one side of the first conveying roller 7 and the second conveying roller 10. The driving wheel 3 and the driven wheel 4 mesh with each other. Guide grooves 8 are provided on both sides of the conveying pipe of the conveyor frame 1, and guide rollers 5 are provided on the guide grooves 8. A threaded adjustment mechanism 2 is provided on one side of the conveyor frame 1.

[0020] In an optional embodiment, the adjusting mechanism 2 includes an adjusting frame 201, a rotating shaft 202, a connecting piece 203, an adjusting rod 204, a limiting groove 205, a limiting block 206, a first drive motor 207, a second drive motor 208, a threaded rod 209, a sliding block 210, a guide rod 211, and a third drive motor 212. The adjusting frame 201 is fixedly connected to one side of the conveying frame 1. The adjusting frame 201 has an adjusting groove 214 inside. The conveying frame 1 is movable on one side of the guide groove 8. A rotating shaft 202 is connected, and a drive rod 9 is provided between the rotating shafts 202. A mounting bracket 213 is fixedly connected in the adjusting groove 214. A threaded rod 209 is movably connected between the mounting brackets 213. Guide rods 211 are fixedly connected to both sides of the threaded rod 209 in the mounting brackets 213. Sliding blocks 210 are sleeved on the guide rods 211 and the threaded rod 209. A third drive motor 212 is fixedly connected to one side of the mounting bracket 213. The output end of the third drive motor 212 is fixedly connected to the threaded rod 209.

[0021] In an optional embodiment, the sliding block 210 is movably connected to the two sides of the adjusting rod 204, and the rotating shaft 202 is fixedly connected to the connecting member 203 in the adjusting groove 214. The connecting member 203 is movably connected to the adjusting rod 204, and a limiting groove 205 is provided on the rotating shaft 202. A limiting block 206 is fixedly connected to the conveyor frame 1, and the limiting block 206 and the limiting groove 205 cooperate with each other.

[0022] In an optional embodiment, a first drive motor 207 is fixedly connected inside the adjusting groove 214, and a first conveying roller 7 is fixedly connected to the output end of the first drive motor 207. A second drive motor 208 is fixedly connected inside the adjusting groove 214, and a second conveying roller 10 is fixedly connected to the output end of the second drive motor 208.

[0023] In an optional embodiment, the rotating shaft 202 is in a comma-shaped configuration, with the protruding end of the rotating shaft 202 engaging with the guide roller 5.

[0024] The working principle of this utility model is as follows: When it is necessary to adjust the yarn tension, the third drive motor 212 is started, and its output end drives the threaded rod 209 to rotate. Due to the threaded transmission relationship between the threaded rod 209 and the sliding block 210, and the guiding effect of the guide rod 211 on the sliding block 210, the sliding block 210 will move linearly along the guide rod 211. The movement of the sliding block 210 is transmitted to the connecting piece 203 through the adjusting rod 204, which in turn drives the rotating shaft 202 to rotate around its axis. Since the rotating shaft 202 has a comma structure, its protruding end cooperates with the guide roller 5. When the rotating shaft 202 rotates, it will change the orientation of the guide roller 5. The guide roller 5 may move up or down a certain distance relative to the guide roller 5, thereby changing the path length of the yarn between the guide roller 5 and the conveying roller, and thus increasing or decreasing the yarn tension. At the same time, the first drive motor 207 and the second drive motor 208 can independently control the speed and direction of rotation of the first conveying roller 7 and the second conveying roller 10 according to actual production needs. For example, when it is necessary to adjust the yarn conveying speed, it can be achieved by changing the output power of the two drive motors, which further improves the control accuracy and flexibility of the conveyor frame for the yarn conveying process and meets the diverse requirements of yarn conveying under different production processes and working conditions.
