Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of yarn guiding devices, specifically a yarn guiding device for rayon yarn with a tension adjustment structure. Background Technology
[0002] In textile production, rayon yarn is an important textile raw material. Its yarn guiding process is a key link in the spinning process. It is necessary to smoothly unwind the yarn from the spool and maintain appropriate tension to ensure the smooth progress of subsequent weaving or knitting processes.
[0003] According to CN219653215U, a yarn guiding device for a spinning frame is disclosed. This technology includes a yarn guiding device body, which comprises a base. A first side plate and a second side plate are respectively connected to both sides of the base. A take-up roller is connected to the upper end of the outer wall of the side corresponding to the first and second side plates. A fixing plate is integrally formed on the outer wall of each side corresponding to the first and second side plates. A through groove is provided on the outer wall of the fixing plate. A sliding shaft is connected to the inner wall of the through groove. A set of adjusting devices is connected to the outer wall of the sliding shaft. An mounting plate is provided at the upper end of the fixing plate. A placement plate with a concave cross-section is connected to the side corresponding to the mounting plate. A conveying device is connected to the inner wall of the placement plate. A motor and a control panel are connected to the outer wall of the first side plate. The output end of the motor is connected to the take-up roller. This technology has the advantage of being able to intercept knotted parts of the yarn, preventing them from affecting the yarn output quality.
[0004] Existing rayon yarn guiding devices have significant shortcomings in terms of bobbin fixation. The existing methods use a single clamping point or mechanical screw locking, which results in an unstable bobbin fixation and uneven force distribution. This makes the bobbin prone to shaking and displacement during high-speed rotation, causing large tension fluctuations during yarn unwinding and affecting the quality stability of subsequent textile processes. Utility Model Content

It uses an expansion mechanism to achieve rapid loading and unloading of the roll, and gear transmission to ensure uniform unwinding. Combined with an adjustable tension system, it precisely controls the yarn tension, significantly improving the efficiency and quality of rayon yarn guiding and meeting diverse production needs.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rayon yarn guiding device with a tension adjustment structure, comprising an adjustment seat, wherein a yarn guiding mechanism is provided on the adjustment seat for guiding the rayon yarn, and the yarn guiding mechanism includes:
[0007] The main component includes a base frame mounted on an adjustment seat, a front axle frame fixed to the front end of the base frame, and a shaft sleeve rotatably mounted through the front axle frame.

[0015] Beneficial effects
[0016] This invention provides a rayon yarn guiding device with a tension adjustment structure. Compared with the prior art, it has the following advantages:
[0017] 1. The three slidable expansion heads on the bobbin base form an inclined plane engagement with the conical sleeve at the front end of the guide rod. Driven by the first cylinder, the axial movement of the conical sleeve can precisely control the radial extension and retraction of the expansion heads, thereby achieving rapid fixation of rayon yarn rolls of different specifications. The output end of the first cylinder drives the guide rod to move the conical sleeve forward, and the spring pushes the expansion heads to retract inward, releasing the fixation of the rayon yarn roll. When it is necessary to replace the roll, the first cylinder drives the guide rod to move the conical sleeve forward, and at the same time, the spring set between the expansion head and the bobbin base generates an elastic restoring force, pushing the three circumferentially distributed expansion heads to retract inward synchronously, quickly releasing the fixation of the roll.
[0018] 2. The motor output drives the drive gear to rotate. The drive gear, through the first transmission gear and the second transmission gear, drives the driven gear to rotate. The driven gear, through the shaft, drives the fixed component to rotate, ensuring that the rayon yarn is evenly unwound from the drum. The guide roller is used to guide the yarn running path. When the cylinder piston rod extends or retracts, it can drive the rotating frame to swing around the fulcrum, thereby changing the spatial position of the tension roller and adjusting the yarn wrap angle in real time to change the tension, meeting the needs of different production processes.

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 - Figure 4 This utility model provides a technical solution: a rayon yarn guiding device with a tension adjustment structure, including an adjustment seat 1, on which a yarn guiding mechanism 2 is provided for guiding the rayon yarn, the yarn guiding mechanism 2 including:
[0026] The main component 21 includes a base frame 211 mounted on the adjustment seat 1, a front axle frame 212 fixed to the front end of the base frame 211, and a shaft sleeve 213 rotatably mounted through the front axle frame 212.
[0027] The fixing component 22 includes a cylinder seat 221 fixed to the front end of the shaft cylinder 213. Three expansion heads 222 are circumferentially distributed and slidably mounted on the cylinder seat 221. The inner wall of the expansion head 222 is a beveled structure. A guide rod 223 is slidably mounted inside the shaft cylinder 213. A conical sleeve 224 is fixed to the front end of the guide rod 223, and the outer wall of the conical sleeve 224 cooperates with the inner wall of the expansion head 222.
[0028] Tensioning component 23 is disposed on fixing component 22 and is used to tension rayon yarn.
[0029] In this embodiment, the three slidable expansion heads 222 on the cylinder base 221 form an inclined surface fit with the conical sleeve 224 at the front end of the guide rod 223. Driven by the first cylinder 215, the axial movement of the conical sleeve 224 can precisely control the radial extension and retraction of the expansion heads 222, thereby achieving rapid fixing of rayon yarn rolls of different specifications.
[0030] Specifically, the fixing component 22 also includes three expansion heads 222 circumferentially distributed on the inner wall of the cylinder seat 221 and used for resetting the expansion heads 222.
[0031] In this embodiment, the output end of the first cylinder 215 drives the guide rod 223 to move the conical sleeve 224 forward, and the spring 225 pushes the expansion head 222 to retract inward, releasing the fixation of the rayon yarn roll. When the roll needs to be replaced, the first cylinder 215 drives the guide rod 223 to move the conical sleeve 224 forward, and at the same time, the spring 225 set between the expansion head 222 and the roll base 221 generates an elastic restoring force, pushing the three circumferentially distributed expansion heads 222 to retract inward synchronously, quickly releasing the fixation of the roll.
[0032] Specifically, the main component 21 also includes a rear axle bracket 214 fixed to the rear end of the base frame 211. A first cylinder 215 is installed at the rear end of the rear axle bracket 214, and the output end of the first cylinder 215 is fixed to the guide rod 223.
[0033] In this embodiment, the first cylinder 215 is used to automatically fix and release the rayon yarn roll, thereby improving the efficiency of the roll changing.
[0034] Specifically, the main component 21 also includes a driven gear 216 fixed to the outer wall of the rear end of the shaft cylinder 213, a first transmission gear 217 rotatably mounted on the front end of the rear axle bracket 214, a second transmission gear 218 fixed to the front end of the first transmission gear 217 and meshing with the driven gear 216 for transmission, and a motor 219 mounted on the rear end of the rear axle bracket 214, with a driving gear 2110 fixed to the output end of the motor 219 and meshing with the first transmission gear 217 for transmission.
[0035] In this embodiment, the output end of the motor 219 drives the drive gear 2110 to rotate. The drive gear 2110 drives the driven gear 216 to rotate through the first transmission gear 217 and the second transmission gear 218. The driven gear 216 drives the fixed component 22 to rotate through the shaft cylinder 213, ensuring that the rayon yarn is evenly unwound from the roll.
[0036] Specifically, the tensioning assembly 23 also includes a bracket 231 fixed to the lower end of the front axle bracket 212. A guide roller 232 is rotatably mounted on the lower right side of the front end of the bracket 231. A rotating frame 233 is rotatably mounted on the lower left side of the front end of the bracket 231. A tensioning roller 234 is rotatably mounted on the lower front end of the rotating frame 233. A second cylinder 235 is pivotally connected to the upper front end of the bracket 231, and the output end of the second cylinder 235 is pivotally connected to the upper end of the rotating frame 233.
[0037] In this embodiment, the guide roller 232 is used to guide the yarn running path. When the cylinder piston rod extends or retracts, it can drive the rotating frame 233 to swing around the fulcrum, thereby changing the spatial position of the tension roller 234 and adjusting the yarn wrap angle in real time to change the tension, so as to meet the needs of different production processes.
[0038] Specifically, the fixing component 22 also includes a baffle 226 fixed to the rear end of the outer wall of the cylinder base 221.
[0039] In this embodiment, during high-speed rotation, the baffle 226 can effectively prevent the drum from axially shifting, thus avoiding problems such as yarn entanglement or uneven tension caused by displacement.
[0040] The working principle and usage process of this utility model are as follows: First, the three slidable expansion heads 222 set on the cylinder base 221 form an inclined surface cooperation with the conical sleeve 224 at the front end of the guide rod 223. Under the drive of the first cylinder 215, the axial movement of the conical sleeve 224 can precisely control the radial extension and retraction of the expansion heads 222, thereby realizing the rapid fixing of rayon yarn rolls of different specifications.
[0041] Then, the guide roller 232 is used to guide the yarn running path. When the cylinder piston rod extends and retracts, it can drive the rotating frame 233 to swing around the fulcrum, thereby changing the spatial position of the tension roller 234 and adjusting the yarn wrap angle in real time to change the tension and meet the needs of different production processes.
[0042] Finally, the output of the motor 219 drives the drive gear 2110 to rotate. The drive gear 2110 drives the driven gear 216 to rotate through the first transmission gear 217 and the second transmission gear 218. The driven gear 216 drives the fixed component 22 to rotate through the shaft cylinder 213, ensuring that the rayon yarn is evenly unwound from the drum.
