Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a yarn guiding device for textile machinery. Background Technology

[0002] In textile production, yarn guiding devices are crucial components ensuring smooth yarn transport, and their performance directly impacts product quality and production efficiency. Traditional yarn guiding devices often suffer from poor structural design, such as poor compatibility of installation components, making precise integration with different types of textile machinery difficult and leading to cumbersome installation and debugging. The guiding components also have inadequate yarn positioning, easily causing yarn deviation, jumping, or even tangling during high-speed operation, increasing frictional damage and potentially causing equipment malfunctions. Furthermore, some yarn guiding devices lack rigidity, easily deforming under prolonged stress, affecting yarn guiding stability and lifespan, and failing to meet the demands of modern textile production for efficient, stable, and precise yarn guiding. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a yarn guiding device for textile machinery to solve the problems of yarn deviation and jumping in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A yarn guiding device for textile machinery includes an installation assembly and a guide assembly disposed on the installation assembly; the installation assembly includes a shaped plate and a positioning bracket disposed on the shaped plate; the shaped plate includes a first vertical plate and a second vertical plate arranged vertically, and a corrugated plate smoothly connecting the first vertical plate and the second vertical plate; the second vertical plate has an installation hole, and the guide assembly is disposed in the installation hole through the installation assembly; the guide assembly includes a guide wheel and a limiting rod located radially on the guide wheel.

[0006] To achieve the above technical solution, when using this yarn guiding device in textile machinery, the yarn first passes through the yarn guiding channel formed by the guide wheel from the yarn feeding direction, then around the outer circumference of the guide wheel, and is then led out via the yarn exit direction. As the yarn moves under traction, it drives the guide wheel to rotate, achieving smooth yarn transport. Simultaneously, the limiting rod limits the position of the yarn in the radial direction of the guide wheel, preventing lateral deviation or jumping during high-speed operation. The corrugated plate structure of the irregularly shaped plate enhances the overall rigidity, and the reasonable layout of the first and second vertical plates ensures the device remains stable under stress. The mounting holes, in conjunction with the mounting components, securely install the entire guiding assembly in the corresponding position within the textile machinery, ensuring a continuous and reliable yarn guiding process.

[0007] In one embodiment of the present invention, the mounting assembly includes a bolt passing through the mounting hole, a bushing embedded in the mounting hole and screwed onto the bolt, and a nut screwed onto the end away from the bolt head and pressing against the second upright plate.

[0008] To achieve the above technical solution, during the installation of the yarn guide device, bolts pass through mounting holes on the second vertical plate and are tightened in conjunction with bushings embedded in the mounting holes. The bushings provide guidance and wear resistance, ensuring the coaxiality and stability of the bolt installation. The other end of the bolt, after passing through the second vertical plate, is locked with a nut. The nut presses against the outer surface of the second vertical plate, thus firmly fixing the entire guide assembly to the shaped plate. The axial preload applied by tightening the nut creates a stable connection between the bolt, bushing, and second vertical plate, preventing loosening due to vibration or changes in yarn traction during equipment operation, ensuring the guide wheel assembly remains in a fixed position and operates smoothly. The bolt, bushing, and nut mechanism enables reliable and detachable installation of the guide assembly on the shaped plate.

[0009] In one embodiment of the present invention, the mounting hole has a tapered hole plate protruding from one side of the guide wheel; the limiting rod includes a circular hole plate for screwing onto the bolt and corresponding to the tapered hole plate, a connecting plate radially disposed on the circular hole plate, and a baffle plate disposed at a perpendicular angle to the connecting plate; a wire passage gap is provided between the baffle plate and the second upright plate.

[0010] To achieve the above technical solution, the limiting rod is fixed to one side of the guide wheel via a circular perforated plate and bolts. A connecting plate extends radially from the circular perforated plate and is perpendicularly connected to the baffle, creating a specific width of thread-passing gap between the baffle and the second vertical plate. The yarn passes through this gap during the yarn guiding process. The baffle restricts the lateral displacement of the yarn on one side of its travel direction, preventing it from shifting or jumping during operation and ensuring stable yarn delivery along the predetermined path.

[0011] In one embodiment of the present invention, a bearing located between the tapered perforated plate and the circular perforated plate is sleeved on the bushing, and the guide wheel is sleeved on the outer periphery of the bearing.

[0012] To achieve the above technical solution, in this yarn guiding device, a bearing is coaxially sleeved on the outer circumference of a bushing and located between a tapered perforated plate and a circular perforated plate, serving as a support and rotational connection. A guide wheel is sleeved on the outer ring of the bearing, allowing it to rotate freely relative to the mounting assembly. When the yarn drives the guide wheel, it achieves low-friction, smooth rotation through the bearing, effectively reducing running resistance and wear. Bolts, the bushing, and the inner ring of the bearing remain fixed, while the guide wheel rotates with the outer ring of the bearing. The tapered and circular perforated plates together axially limit the bearing, preventing axial movement during high-speed operation and ensuring the guide wheel rotates stably in a precise position, achieving efficient and smooth yarn guidance.

[0013] In one embodiment of the present invention, the positioning bracket includes a mounting plate disposed on the first upright plate, a first positioning plate disposed on the mounting plate and parallel to the first upright plate, and a second positioning plate disposed above the first positioning plate.

[0014] To achieve the above technical solution, the positioning bracket is fixedly connected to the first upright plate via a mounting plate, forming a stable support foundation; the first positioning plate and the second upright plate are set parallel to each other on the mounting plate, maintaining a certain distance from the first upright plate, and are used to initially define the lateral position of the yarn guiding device on the equipment mounting surface; the second positioning plate is located above the first positioning plate, and together with the first positioning plate, they form a stepped positioning structure, which can cooperate with the corresponding positioning groove or reference surface on the textile machinery frame during installation to achieve precise positioning of the device in the vertical and horizontal directions.

[0015] In one embodiment of the present invention, a first positioning hole is provided on the first positioning plate, a second positioning hole is provided on the second positioning plate, and a third positioning hole corresponding to the first positioning hole is provided on the first upright plate.

[0016] To achieve the above technical solution, a multi-dimensional, high-precision positioning system is formed by setting a first positioning hole on the first positioning plate, a second positioning hole on the second positioning plate, and a third positioning hole corresponding to the first positioning hole on the first upright plate. This multi-point, multi-directional hole matching method effectively avoids the cumulative error during the installation process and improves the assembly repeatability accuracy.

[0017] As described above, the yarn guiding device for textile machinery of this utility model has the following beneficial effects: Through the synergistic effect of the guide wheel and the limiting rod, combined with the reasonable setting of the yarn passage gap, the lateral deviation and jump of the yarn are effectively limited, significantly reducing the risk of yarn friction damage and entanglement, and improving the stability and reliability of yarn guiding; In terms of installation adaptability, the multi-positioning plate and multi-positioning hole design of the positioning bracket, combined with the detachable bolt, bushing, and nut installation structure, not only achieves high-precision and rapid docking between the device and textile machinery, but also enhances the adaptability to different equipment and greatly simplifies the installation and debugging process; In terms of structural stability, the corrugated plate structure of the irregular plate and the multi-vertical plate layout significantly improve the overall rigidity, effectively disperse the impact caused by yarn tension, and, combined with the low-friction rotation design of the bearing, reduce component wear and extend the service life of the device, thereby better meeting the needs of efficient textile production.

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Please see Figures 1 to 4This utility model provides a yarn guiding device for textile machinery, including an installation assembly and a guiding assembly disposed on the installation assembly; the installation assembly includes a shaped plate and a positioning bracket disposed on the shaped plate; the shaped plate includes a first vertical plate 1 and a second vertical plate 2 arranged vertically, and a corrugated plate smoothly connecting the first vertical plate 1 and the second vertical plate 2; the second vertical plate 2 has an installation hole 4, and the guiding assembly is disposed in the installation hole 4 through the installation assembly; the guiding assembly includes a guide wheel 5 and a limiting rod 6 located radially on the guide wheel 5.

[0026] When using this yarn guiding device in textile machinery, the yarn first passes through the yarn guiding channel formed by the guide wheel 5 from the yarn feeding direction, then around the outer circumference of the guide wheel 5, and is then led out through the yarn exit direction. As the yarn moves under traction, it drives the guide wheel 5 to rotate, achieving smooth yarn transport. Simultaneously, the limiting rod 6 limits the position of the yarn in the radial direction of the guide wheel 5, preventing lateral deviation or jumping during high-speed operation. The corrugated plate structure of the irregularly shaped plate enhances the overall rigidity, and the reasonable layout of the first vertical plate 1 and the second vertical plate 2 ensures the device remains stable under stress. The mounting holes 4, in conjunction with the mounting components, securely install the entire guiding assembly in the corresponding position on the textile machinery, ensuring a continuous and reliable yarn guiding process.

[0027] The mounting assembly includes a bolt 7 passing through the mounting hole 4, a bushing 8 embedded in the mounting hole 4 and screwed onto the bolt 7, and a nut 9 screwed onto the end away from the head of the bolt 7 and pressing against the second upright plate 2.

[0028] During the installation of the yarn guiding device, bolt 7 passes through the mounting hole 4 on the second vertical plate 2 and is tightened in conjunction with the bushing 8 embedded in the mounting hole 4. The bushing 8 serves as a guide and provides wear resistance, ensuring the coaxiality and stability of bolt 7. After passing through the second vertical plate 2, the other end of bolt 7 is locked by nut 9. Nut 9 presses against the outer surface of the second vertical plate 2, thus firmly fixing the entire guiding assembly to the irregular plate. The axial preload applied by tightening nut 9 forms a stable connection between bolt 7, bushing 8, and the second vertical plate 2, preventing loosening due to vibration or changes in yarn traction during equipment operation, and ensuring that the guide wheel 5 assembly remains in a fixed position and runs smoothly during operation. Through the cooperation structure of bolt 7, bushing 8, and nut 9, a reliable and detachable installation of the guiding assembly on the irregular plate is achieved.

[0029] The mounting hole 4 has a tapered hole plate 10 protruding from one side of the guide wheel 5; the limiting rod 6 includes a circular hole plate 61 for screwing onto the bolt 7 and corresponding to the tapered hole plate 10, a connecting plate 62 arranged radially on the circular hole plate 61, and a baffle 63 arranged at a perpendicular angle to the connecting plate 62; a wire passage gap 11 is provided between the baffle 63 and the second upright plate 2.

[0030] The limiting rod 6 is fixed to one side of the guide wheel 5 by connecting its circular perforated plate 61 to the bolt 7. The connecting plate 62 extends radially from the circular perforated plate 61 and is perpendicularly connected to the baffle 63, forming a thread-passing gap 11 of a specific width between the baffle 63 and the second vertical plate 2. The yarn passes through this thread-passing gap 11 during the yarn guiding process. The baffle 63 restricts the lateral displacement of the yarn on one side of the yarn's travel direction, preventing it from deviating or jumping during operation and ensuring that the yarn is stably conveyed along the predetermined path.

[0031] The bushing 8 is fitted with a bearing 12 located between the tapered perforated plate 10 and the circular perforated plate 61, and the guide wheel 5 is fitted around the outer periphery of the bearing 12.

[0032] In this yarn guiding device, the bearing 12 is coaxially mounted on the outer circumference of the bushing 8 and located between the tapered perforated plate 10 and the circular perforated plate 61, serving as a support and rotational connection. The guide wheel 5 is fitted onto the outer ring of the bearing 12, allowing it to rotate freely relative to the mounting assembly. When the yarn drives the guide wheel 5, the guide wheel 5 achieves low-friction and smooth rotation through the bearing 12, effectively reducing running resistance and wear. The bolt 7, bushing 8, and inner ring of the bearing 12 are fixed, while the guide wheel 5 rotates with the outer ring of the bearing 12. The tapered perforated plate 10 and the circular perforated plate 61 together axially limit the bearing 12, preventing axial movement during high-speed operation and ensuring that the guide wheel 5 rotates stably in a precise position, achieving efficient and smooth yarn guidance.

[0033] The positioning bracket includes a mounting plate 13 disposed on the first upright plate 1, a first positioning plate 14 disposed on the mounting plate 13 and parallel to the first upright plate 1, and a second positioning plate 15 disposed above the first positioning plate 14.

[0034] The positioning bracket is fixedly connected to the first upright plate 1 via the mounting plate 13, forming a stable support base; the first positioning plate 14 and the second upright plate 2 are arranged parallel to each other on the mounting plate 13, maintaining a certain distance from the first upright plate 1, and are used to initially limit the lateral position of the yarn guiding device on the equipment mounting surface; the second positioning plate 15 is located above the first positioning plate 14, and together with the first positioning plate 14, they form a stepped positioning structure, which can cooperate with the corresponding positioning groove or reference surface on the textile machinery frame during installation to achieve precise positioning of the device in the vertical and horizontal directions.

[0035] The first positioning plate 14 has a first positioning hole 16, the second positioning plate 15 has a second positioning hole 17, and the first upright plate 1 has a third positioning hole 18 corresponding to the first positioning hole 16.

[0036] By setting a first positioning hole 16 on the first positioning plate 14, a second positioning hole 17 on the second positioning plate 15, and a third positioning hole 18 corresponding to the first positioning hole 16 on the first upright plate 1, a multi-dimensional, high-precision positioning system is formed. This multi-point, multi-directional hole matching method effectively avoids the cumulative error during the installation process and improves the assembly repeatability accuracy.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
