Description

Technical Field

[0001] This utility model relates to the field of blended yarn plying technology, specifically a blended yarn plying conductor mechanism with a fine-tuning component. Background Technology

[0002] Blended yarn production involves bundling and plying multiple strands of different fibers to form a single blended yarn. In the production process of blended yarn, the plying conductor mechanism is a key piece of equipment. Its function is to precisely guide and converge multiple strands of yarn with different materials or properties, so that they are evenly plyed to form a yarn product that meets quality requirements.

[0003] Referring to the patent document: Patent Publication No. CN219079752U, published on May 26, 2023, a device for bundling and twisting blended yarns is disclosed. The device includes a housing and a twisting and stranding device and a take-up device fixedly connected to the inner surface of the housing. A support plate is fixedly connected to the bottom of the inner surface of the housing. A swing shaft is fixedly connected to the outer surface of the support plate. Swing teeth are rotatably connected to the outer surface of the swing shaft. A rack is meshed with the outer surface of the swing teeth. This device for bundling and twisting blended yarns achieves the effect of the rack driving the lead-in block to swing left and right simply by rotating the swing rod in one direction. This solves the problem in existing lead-in devices where the left and right swing is not smooth enough due to inertia and the change in current direction when the motor reverses direction, affecting the efficiency and aesthetics of take-up.

[0004] Currently, traditional blended yarn plying guide mechanisms mostly use fixed guide wheels or simple adjustable guide devices to guide the direction of blended yarns and make them ply evenly. However, different types of yarns require different tensions, and the guide devices cannot quickly and adaptively adjust the tension for different types of yarns. This leads to uneven plying tightness and uneven twist due to uneven tension, which requires frequent machine stops to replace parts, reducing production efficiency and increasing production costs.

[0005] Therefore, this utility model provides a blended yarn stranding conductor mechanism with a fine-tuning component. Utility Model Content

[0006] To address the problem that existing methods for plying blended yarns often use fixed guide wheels or simple adjustable guide devices, which prevent the tension from being adjusted according to different types of yarn, the purpose of this invention is to provide a blended yarn plying guide mechanism with a fine-tuning component.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a blended yarn plying guide mechanism with a fine-tuning component, comprising a frame and a blended yarn. One side of the frame is provided with a traction mechanism for adjusting the tension of the blended yarn during plying. The traction mechanism includes:

[0008] The guiding assembly includes a first traction roller fixed to one side of the frame, a second traction roller on the lower side of the frame, a third traction roller fixedly installed on the upper part of the frame on the side of the second traction roller, a moving rod on the upper side of the frame, a spring detachably installed on one side of the moving rod, a swing rod rotatably installed on the upper side of the frame, the other end of the spring detachably installed on the upper side of the swing rod, a fourth traction roller fixedly installed on one end of the swing rod, and a pressure sensor detachably installed on the upper side of the frame, with the lower part of the swing rod in contact with the upper part of the pressure sensor.

[0009] A limiting component, located on the upper side of the frame, is used to limit one end of the blended yarn.

[0010] Preferably, the limiting component includes a fixing frame that is detachably mounted on one side of the upper part of the frame, and a limiting ring is rotatably mounted on the upper side of the fixing frame.

[0011] Preferably, the guide assembly further includes a first screw rotatably mounted on the lower part of the frame, and a second traction roller having one side threaded onto the upper part of the first screw.

[0012] Preferably, the guide assembly further includes a second screw rotatably mounted on the upper part of the frame, and one end of the moving rod is threaded onto the upper part of the second screw.

[0013] Preferably, a worm gear is fixedly installed on one side of the limiting ring, and a worm is rotatably installed on one side of the fixing frame, with the worm and the worm gear meshing with each other.

[0014] Preferably, a ceramic bushing is embedded in the inner wall surface of the limiting ring. The ceramic bushing is distributed on both sides of the arc-shaped limiting groove of the limiting ring to reduce the friction coefficient between the blended yarn and the limiting ring and reduce the wear of the blended yarn.

[0015] Beneficial effects

[0016] This invention provides a blended yarn stranding guide mechanism with a fine-tuning component. Compared with the prior art, it has the following advantages:

[0017] 1. This application monitors yarn tension in real time using a pressure sensor. With precise adjustment of the No. 1 and No. 2 screws, the tension can be dynamically adjusted according to the blended yarns of different linear densities and materials. When the pressure sensor detects abnormal tension, the tension can be quickly adjusted by adjusting the height of the No. 2 traction roller and the spring preload, effectively avoiding problems such as uneven ply tension and uneven twist caused by uneven tension.

[0018] 2. This application guides and conveys the blended yarn through a limiting ring, and at the same time uses a worm gear self-locking structure to adjust the angle of the limiting ring, so that it can quickly adapt to the plying device with different installation heights and orientations, ensuring stable yarn feeding.

[0024] 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.

[0025] Please see Figure 1-4This utility model provides a technical solution: a blended yarn plying guide mechanism with a fine-tuning component, comprising a frame 1 and a blended yarn 3. The blended yarn 3 passes through a first traction roller 211, a second traction roller 212, a third traction roller 214, and a fourth traction roller 219, respectively, and is connected to a fixed component in the plying device. A traction mechanism 2 is provided on one side of the frame 1 for adjusting the tension of the blended yarn 3 during plying. The traction mechanism 2 includes:

[0026] The guide assembly 21 includes a first traction roller 211 fixed to one side of the frame 1, a second traction roller 212 provided on the lower side of the frame 1, a third traction roller 214 fixedly installed on the upper part of the frame 1 on the side of the second traction roller 212, a moving rod 217 provided on the upper side of the frame 1, a spring 216 detachably installed on one side of the moving rod 217, a swing rod 215 rotatably installed on the upper side of the frame 1, the other end of the spring 216 detachably installed on the upper side of the swing rod 215, a fourth traction roller 219 fixedly installed on one end of the swing rod 215, and a pressure sensor 11 detachably installed on the upper side of the frame 1. The pressure sensor is a high-precision strain gauge sensor with a range of 0-50N and an accuracy of ±0.1N. It can accurately detect the pressure signal transmitted by the swing rod 215, providing data support for yarn tension control. The lower part of the swing rod 215 is in contact with the upper part of the pressure sensor 11.

[0027] The limiting component 22 is set on the upper side of the frame 1 and is used to limit one end of the blended yarn 3.

[0028] The limiting component 22 includes a detachable fixing frame 221 installed on one side of the upper part of the frame 1. A limiting ring 222 is rotatably installed on the upper side of the fixing frame 221. The fixing frame 221 is made of high-strength aluminum alloy and is detachably connected to the frame 1 by bolts, which facilitates later maintenance and replacement. The setting of the fixing frame 221 and the limiting ring 222 can limit the blended yarn 3 at the end of the traction mechanism 2 to ensure the stability of the blended yarn 3 entering the plying device.

[0029] The guide assembly 21 also includes a first screw 213 rotatably mounted on the lower part of the frame 1, and a second traction roller 212 with one side threaded onto the upper part of the first screw 213. By rotating the first screw 213, the second traction roller 212 can be displaced in the vertical direction, with a displacement accuracy of up to 0.1mm, thereby flexibly adjusting the height difference of the yarn guide path.

[0030] The guide assembly 21 also includes a second screw 218 rotatably mounted on the upper part of the frame 1. One end of the moving rod 217 is threaded onto the upper part of the second screw 218. When the second screw 218 is rotated, the moving rod 217 moves along the axis of the second screw 218, thereby changing the initial compression of the spring 216. This adjustment method can continuously adjust the preload of the spring 216 within a stroke range of 0-20mm to adapt to the tension range required by blended yarns 3 with different linear densities and materials.

[0031] A worm gear 223 is fixedly installed on one side of the limiting ring 222, and a worm 224 is rotatably installed on one side of the fixing frame 221. The worm 224 and the worm gear 223 are meshed together. The structural design of the worm gear 224 and the worm 223 enables it to have a self-locking function, ensuring that when the worm 224 is rotated to drive the worm gear 223 to adjust the angle of the limiting ring 222, it can self-lock to avoid angle deviation. The end of the worm 224 is provided with an anti-slip knurled structure, which is convenient for manual adjustment by the operator. At the same time, the worm 224 can also be connected to an external servo motor to realize automated angle adjustment, and the adjustment angle resolution can reach 1°.

[0032] A ceramic bushing is embedded in the inner wall surface of the limiting ring 222. The ceramic bushing is distributed on both sides of the arc-shaped limiting groove of the limiting ring 222 to reduce the friction coefficient between the blended yarn 3 and the limiting ring 222 and reduce the wear of the blended yarn 3. The embedding process adopts high-temperature brazing technology to ensure that the ceramic bushing is tightly bonded to the inner wall of the limiting ring 222 and can withstand the long-term friction of the high-speed running yarn.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, the blended yarn 3 passes through the first traction roller 211, the second traction roller 212, the third traction roller 214, and the fourth traction roller 219, and then through the limiting ring 222, fixing its end to the plying device. The plying device of the blended yarn 3 is activated, thereby pulling the blended yarn 3 to move. At this time, under the tension, one end of the swing rod 215 moves downward, so that the swing rod 215 comes into contact with the pressure sensor 11. At the same time, the spring 216 is pulled to detect elastic deformation, so that it produces elastic deformation on the swing rod 215, which is used to control the tension at the end of the blended yarn 3. The moving rod 217 can be moved by rotating the second screw 218, so that the deformation of the spring 216 increases or decreases, so as to adjust the tension of the spring 216 according to different blended yarn 3 materials, thereby controlling the tension at the end of the blended yarn 3.

[0035] The pressure sensor 11 detects the pressure value when the swing rod 215 contacts. When the pressure value is less than the set range, the tension of the blended yarn 3 is low. By rotating the first screw 213, the second traction roller 212 is moved downward, thereby adjusting the distance between the second traction roller 212 and the first traction roller 211 and the third traction roller 214, thereby increasing the tension of the blended yarn 3. When the pressure value is greater than the set range, the first screw 213 is rotated in the opposite direction to reduce the tension of the blended yarn 3.

[0036] When the traction mechanism 2 is installed at different heights, the worm gear 224 can be rotated to drive the worm wheel 223 to rotate, thereby adjusting the angle of the limiting ring 222, which facilitates the installation and plying of the blended yarn 3 and the plying device.
