Description

Technical Field

[0001] This utility model relates to the field of nylon air-coated yarn production technology, specifically a pre-winding mechanism applied to the production of nylon air-coated yarn. Background Technology

[0002] Nylon air-coated yarn is a composite yarn made from nylon filament and spandex filament through air-coating process. The pre-stretching and winding structure of nylon air-coated yarn is formed by regularly spraying nylon filament onto spandex core yarn with high-compressed air to form a rhythmic network of dots.

[0003] For example, Chinese Patent CN202509195U discloses an air-coated yarn machine, belonging to the field of textile machinery. This utility model includes a frame and a yarn drum mounting device, a spandex mounting device, an overfeed roller device, a sensor, a network nozzle, a pressing device, and a winding assembly mounted on the frame. Its characteristic is that the air-coated yarn machine has a vertical structure, with the yarn drum mounting device and the overfeed roller device arranged vertically, and the spandex mounting device and the overfeed roller device arranged vertically. The overfeed roller device, sensor, network nozzle, pressing device, and winding assembly are arranged sequentially from top to bottom. This utility model produces yarn with good forming quality and is safe and economical to use. Traditional pre-tensioning winding mechanisms are easily affected by the tension during yarn transport, making it difficult to control the yarn tension effectively. When the tension changes, the number of winding network points changes, affecting the quality of the finished covered yarn. Therefore, a pre-tensioning winding mechanism for nylon air-coated yarn production is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a pre-winding mechanism for the production of nylon air-coated yarn, which has advantages such as adjustable tension during the yarn conveying process, thus solving the problem of yarn tension changes during traditional conveying.

[0005] (II) Technical Solution To achieve the goal of causing changes in yarn tension during the aforementioned conveying process, this utility model provides the following technical solution: a pre-winding mechanism for the production of nylon air-coated yarn, comprising: The mounting frame has a first guide wheel, a tension adjusting wheel and a second guide wheel installed sequentially from top to bottom on its outer surface. An adjustment component is provided inside the mounting frame at one end of the tension adjusting wheel, and the position of the tension adjusting wheel can be adjusted by adjusting the adjustment component. A wire winding cylinder is mounted on the outer surface of the mounting frame and is located below the second guide wheel. A network nozzle is fixedly mounted on the outer surface of the wire winding cylinder, and the output end of the network nozzle is connected to the interior of the wire winding cylinder.

[0006] Preferably, a bundling frame is fixedly installed on the outer surface of the mounting frame above the yarn winding cylinder. Multiple strands of yarn pass through the bundling frame and enter the yarn winding cylinder. High-pressure airflow is sprayed out through the network nozzle to regularly press the nylon filaments onto the spandex core yarn, forming rhythmic network points.

[0007] Preferably, the adjustment component includes a groove formed on the outer surface of the mounting frame, a slider is provided inside the groove, and the slider is slidably connected to the mounting frame through the groove. One end of the groove is fixedly connected to the outer surface of the tension adjusting wheel. When the tension of the yarn is too high, the yarn pushes the tension adjusting wheel inward, thereby shortening the path of yarn delivery.

[0008] Preferably, a guide rod is fixedly installed inside the chute, and a slider is sleeved on the outer surface of the guide rod. A guide frame is sleeved at one end of the outer surface of the guide rod, and a spring is sleeved on the outer surface of the guide rod between the slider and the guide frame. When the tension adjusting wheel moves, it will slide the slider along the chute and compress the spring on the surface of the guide rod to reduce the tension. Conversely, the spring will push the tension adjusting wheel outward to increase the thread conveying path and increase the tension, so as to maintain the stability of the tension during the thread conveying process.

[0009] Preferably, a guide tube is fixedly installed on the outer surface of one end of the guide frame, and turntables are rotatably installed on both sides of the mounting frame. A screw is fixedly installed on one end of the turntable, and the screw is threadedly connected to the guide tube. Rotating one side of the turntable drives the screw to rotate, causing the guide frame to slide along the guide rod, thereby adjusting the distance between the guide frame and the slider.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model provides a pre-winding mechanism for the production of nylon air-coated yarn, which has the following advantages: By setting a tension adjusting wheel, the thread is guided and transported by passing around the first guide wheel, the tension adjusting wheel and the second guide wheel in sequence during the thread transport process. When the thread tension is too high, the thread pushes the tension adjusting wheel inward, thereby shortening the thread transport path and reducing the tension. Conversely, the spring will push the tension adjusting wheel outward, increasing the thread transport path and increasing the tension, so as to maintain the stability of the tension during the thread transport process.

[0013] 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.

[0014] Please see Figure 1-3 The present invention provides the following technical solution: a pre-stretching and winding mechanism for the production of nylon air-coated yarn, including a mounting frame 1, wherein a first guide wheel 11, a tension adjusting wheel 3 and a second guide wheel 12 are sequentially mounted on the outer surface of the mounting frame 1 from top to bottom, and an adjusting component is provided at one end of the tension adjusting wheel 3 inside the mounting frame 1, and the position of the tension adjusting wheel 3 is adjusted by adjusting the adjusting component; In this embodiment, the adjustment component includes a groove 31 formed on the outer surface of the mounting frame 1. A slider 32 is provided inside the groove 31, and the slider 32 is slidably connected to the mounting frame 1 through the groove 31. One end of the groove 31 is fixedly connected to the outer surface of the tension adjusting wheel 3. When the tension of the thread is too high, the thread pushes the tension adjusting wheel 3 inward, thereby shortening the path of the thread transport.

[0015] The guide rod 33 is fixedly installed inside the slide groove 31, and the slider 32 is sleeved on the outer surface of the guide rod 33. A guide frame 35 is sleeved on one end of the outer surface of the guide rod 33. A spring 34 is sleeved on the outer surface of the guide rod 33 between the slider 32 and the guide frame 35. When the tension adjusting wheel 3 moves, it will slide the slider 32 along the slide groove 31 and squeeze the spring 34 on the surface of the guide rod 33 to reduce the tension. Conversely, the spring 34 will push the tension adjusting wheel 3 outward to increase the thread conveying path and increase the tension, so as to maintain the tension stability during the thread conveying process.

[0016] In this embodiment, a guide tube 36 is fixedly installed on the outer surface of one end of the guide frame 35, and a turntable 38 is rotatably installed on both sides of the mounting frame 1. A screw 37 is fixedly installed on one end of the turntable 38, and the screw 37 is threadedly connected to the guide tube 36. Rotating one side of the turntable 38 will drive the screw 37 to rotate, thereby causing the guide frame 35 to slide along the guide rod 33 and adjusting the distance between the guide frame 35 and the slider 32. In this embodiment, the wire winding cylinder 2 is installed on the outer surface of the mounting frame 1, and the wire winding cylinder 2 is located below the second guide wheel 12. A network nozzle 21 is fixedly installed on the outer surface of the wire winding cylinder 2, and the output end of the network nozzle 21 is connected to the interior of the wire winding cylinder 2.

[0017] The mounting frame 1 has a bundled frame 13 fixedly installed on the outer surface of the mounting frame 1 above the yarn winding cylinder 2. Multiple strands of yarn pass through the bundled frame 13 and enter the yarn winding cylinder 2. High-pressure airflow is sprayed out through the network nozzle 21 to regularly spray the nylon filaments onto the spandex core yarn, forming rhythmic network points.

[0018] The working principle of this embodiment is as follows: When conveying the filaments, the filaments are guided and conveyed by passing through the first guide wheel 12, the tension adjusting wheel 3 and the second guide wheel 12 in sequence, so that multiple strands of filaments pass through the bundle frame 13 and enter the filament winding drum 2. High-pressure airflow is sprayed out through the network nozzle 21 to regularly spray the nylon filaments onto the spandex core filaments to form rhythmic network points. When the tension of the thread is too high, the thread pushes the tension adjusting wheel 3 inward, thereby shortening the path of the thread conveying. During the movement of the tension adjusting wheel 3, the slider 32 will slide along the groove 31, squeezing the spring 34 on the surface of the guide rod 33 to reduce the tension. Conversely, the spring 34 will push the tension adjusting wheel 3 outward, increasing the path of the thread conveying and increasing the tension, so as to maintain the stability of the tension during the thread conveying process. When it is necessary to adjust the initial elastic force of the spring 34, the turntable 38 on one side can be rotated. The rotation drives the screw 37 to rotate. The screw 37 is threadedly connected to the guide tube 36 on the guide frame 35, which drives the guide frame 35 to slide along the guide rod 33. Adjusting the distance between the guide frame 35 and the slider 32 adjusts the initial length of the spring 34 and thus adjusts the elastic force of the spring 34.
