Description

Technical Field

[0001] This utility model relates to the field of yarn straightener technology, and in particular to a yarn straightener for textile machines. Background Technology

[0002] In the textile production process, the quality of yarn finishing directly affects the stability of subsequent weaving processes and the final product quality. During processing and transportation, yarn is prone to static electricity due to factors such as friction and dry environment. The presence of static electricity can cause problems such as yarn tangling, dust attraction, and fuzzing, which seriously affect the yarn management effect and weaving precision.

[0003] However, existing yarn straighteners for textile machines generally suffer from unreasonable static elimination structure design: their static elimination components are mostly fixed installations, making it impossible to flexibly adjust their relative position to the yarn according to actual processing needs.

[0004] Therefore, it is necessary to provide a yarn straightener for textile machines to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a yarn straightener for textile machines, which solves the problems mentioned in the background art.

[0006] To address the aforementioned technical problems, this utility model provides a yarn guide for a textile machine. The top surface of the device body is provided with a first mounting frame and a third mounting frame, with a second mounting frame located between the first and third mounting frames. A motorized telescopic rod is vertically mounted on the top surface of the second mounting frame. The output end of the motorized telescopic rod passes through the top surface of the second mounting frame and is connected to a mounting block. A static eliminator is installed between the two mounting blocks. When the motorized telescopic rod extends or retracts, it can drive the mounting blocks and the static eliminator to move synchronously, thereby adjusting the relative position of the static eliminator and the yarn, enhancing the targeted static elimination.

[0007] Preferably, the first mounting bracket has a first connecting ring on its end face, and the third mounting bracket has a second connecting ring on its end face. The test yarn is connected between the first and second connecting rings. A test rod is provided at one end of the mounting block, and a pressure sensor is mounted on the circumferential side of the test rod. The test yarn is transmitted synchronously with the actual yarn, and the pressure sensor can sense the tension change during the transmission of the test yarn, providing a basis for adjusting the position of the static eliminator.

[0008] Preferably, the traverse yarn guiding mechanism is mounted on the third mounting frame. It guides the yarn to move in an orderly manner during transmission, preventing yarn deviation or accumulation and ensuring the stability of yarn transmission.

[0009] Preferably, the winding mechanism is installed inside the first mounting frame, and the drive motor is connected to the winding mechanism. When the drive motor operates, it can drive the winding mechanism to start, thereby winding the yarn and providing power for yarn transmission.

[0010] Preferably, two test yarns are provided, and the two test yarns are symmetrically installed on both sides of the device body with the device body as the center. The symmetrical arrangement of the test yarns can more comprehensively simulate the transmission state of the yarn at different positions and improve the accuracy of tension detection.

[0011] Preferably, the support legs are installed at the bottom of the device body, with multiple support legs distributed at the four corners of the bottom of the device body, and the distance between each support leg is uniform. The support legs can provide stable support for the device body and prevent the device from shaking during operation.

[0012] Preferably, the controller is mounted on the device body. The controller can receive signals from the pressure sensor and control the extension and retraction of the electric telescopic rod according to the signals, while coordinating the operation of components such as the winding mechanism and the traverse yarn guiding mechanism to ensure the orderly operation of the entire device.

[0013] Compared with related technologies, the yarn straightener for textile machines provided by this utility model has the following beneficial effects: Compared to existing technologies, this yarn straightener for textile machines, with its combination of an electric telescopic rod and an anti-static bar, effectively solves the core defect of fixed installation of anti-static components in existing yarn straighteners. The electric telescopic rod can drive the anti-static bar to flexibly adjust its relative position to the yarn, adapting to yarns of different materials and specifications, as well as dynamic positional changes during yarn transmission, achieving precise targeted anti-static elimination. This significantly reduces problems such as yarn tangling, dust adsorption, and fuzzing caused by static electricity, significantly improving yarn straightening performance, ensuring the stability of subsequent weaving processes, and improving weaving precision, thus laying a solid foundation for the quality of the final product. This design is adaptable to diverse processing scenarios in textile production, enhancing the versatility and practicality of the device, reducing production losses caused by static electricity problems, and improving production efficiency.

[0014] Compared to existing technologies, this yarn guide for textile machines simulates the actual yarn transmission conditions through two symmetrically installed test yarns. Pressure sensors on the test rods accurately capture tension fluctuations during yarn transmission, converting mechanical signals into electrical signals that are fed back to the controller. This structure provides timely warnings of abnormal conditions such as overstretching or slack in the yarn, offering data support for the controller to adjust the electric telescopic rod. This ensures the static eliminator is always in its optimal working position, while preventing yarn damage due to tension imbalance. This further improves the process controllability of textile production, reduces downtime due to processing failures, stabilizes yarn quality, and provides uniformly tensioned, well-maintained yarn for subsequent weaving, contributing to improved overall production pass rate and product consistency.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0019] Please refer to the following: Figure 1-4 A yarn straightener for textile machines is disclosed. The main body 1 serves as the overall mounting base, with a first mounting frame 2 and a third mounting frame 6 fixedly mounted on its top surface, maintaining a relatively stable spacing between them. A second mounting frame 4 is positioned between the first and third mounting frames 2 and fixed in place, forming an intermediate mounting carrier. An electric telescopic rod 9 is fixed vertically to the top surface of the second mounting frame 4, with its output end penetrating the top of the second mounting frame 4 and forming a rigid connection with a mounting block 12, ensuring accurate power transmission. Static eliminator 13 is installed at both ends between the two mounting blocks 12, horizontally corresponding to the yarn transmission path. Mechanically, the extension and retraction of the electric telescopic rod 9 directly drives the mounting blocks 12 to move synchronously, thereby adjusting the position of the static eliminator 13 vertically, achieving flexible adaptation to the relative distance with the yarn. This connection structure breaks the limitations of traditional fixed installation of static eliminator components. Through an adjustable design, the static eliminator 13 precisely addresses the static eliminator requirements of different yarns and working conditions, effectively reducing yarn entanglement, dust adsorption, and other problems, ensuring yarn straightening effect and weaving precision.

[0020] The static eliminator rod 13 uses an ion fan, operates at a voltage of 5-10kV, and releases ≥10 ions.6 With ions / cm³, the effective elimination distance is 5-20mm, and it is suitable for the common static voltage range of textile yarns (1-10kV). Example

[0021] Please refer to the following: Figure 1-4 The first mounting bracket 2 has a first connecting ring 14 fixedly mounted on its end face, and the third mounting bracket 6 has a second connecting ring fixedly mounted on its corresponding end face, with the two connecting rings coaxially aligned. The test yarn 15 is connected to the first connecting ring 14 and the second connecting ring at both ends, and is in a tensioned state. One end of the mounting block 12 is fixedly connected to the test rod 11, whose extension direction matches the yarn transmission direction. The pressure sensor 10 is fixedly attached to the circumference of the test rod 11, ensuring effective contact with the test yarn 15. Mechanically, the test yarn 15 is transmitted synchronously with the main yarn, and its tension changes directly act on the pressure sensor 10, which converts the mechanical signal into an electrical signal. This structure, through the linkage detection of the test yarn 15 and the main yarn, captures tension fluctuations in real time, providing data support for subsequent position adjustments. It also provides early warning of abnormal yarn tension, preventing yarn damage and ensuring the stability of static electricity elimination and yarn straightening processes. Example

[0022] Please refer to the following: Figure 1-4 After the third mounting frame 6 is fixed to the device body 1, the traverse yarn guiding mechanism 5 is fixedly installed at the preset position of the third mounting frame 6. Its installation height is precisely matched with the yarn transmission path to ensure that the yarn can pass through smoothly. In terms of mechanical cooperation, the traverse yarn guiding mechanism 5 limits and guides the yarn in transmission through its own guiding structure or reciprocating motion. This connection structure makes the traverse yarn guiding mechanism 5 and the third mounting frame 6 form a stable whole, which can effectively prevent yarn deviation, accumulation or tangling, guide the yarn to move orderly along the preset path, create a stable yarn posture for the precise action of the static elimination rod 13, and ensure the continuity of the yarn handling process.

[0023] The lateral yarn guiding mechanism 5 includes a horizontal slide rail, a sliding seat, a yarn guide wheel, and a reciprocating cylinder. The horizontal slide rail is fixedly mounted on the third mounting bracket 6. The sliding seat slides in conjunction with the slide rail. The yarn guide wheel is rotatably mounted on the sliding seat. The reciprocating cylinder is connected to the sliding seat and drives it to reciprocate along the slide rail. The yarn passes through the yarn guide wheel, and the reciprocating movement of the sliding seat guides the yarn to be evenly distributed laterally, preventing offset and accumulation. Example

[0024] Please refer to the following: Figure 1-4The winding mechanism 3 is assembled and fixed inside the cavity of the first mounting frame 2, with its yarn winding component aligned with the external transmission path. The drive motor 8 is installed at the corresponding position on the first mounting frame 2, and its power output end is connected to the power input end of the winding mechanism 3 to ensure efficient power transmission. Mechanically, after the drive motor 8 starts, it drives the core component of the winding mechanism 3 to rotate through the transmission structure, thereby winding the yarn. This connection structure uses the drive motor 8 as the power source and the winding mechanism 3 as the execution component, providing continuous and stable power for yarn transmission through power transmission, ensuring balanced yarn transmission speed and tension, and laying the foundation for subsequent processes.

[0025] The winding mechanism 3 includes a winding shaft, a bearing housing, and a transmission gear set. The bearing housing is fixedly installed inside the first mounting bracket 2. The winding shaft is rotatably connected to the bearing housing via bearings. The transmission gear set meshes with both the winding shaft and the output shaft of the drive motor 8. The drive motor 8 drives the winding shaft to rotate via the transmission gear set, achieving stable yarn winding. Example

[0026] Please refer to the following: Figure 1-4 After the first connecting ring 14 and the second connecting ring are installed, the two test yarns 15 are connected to their respective connecting rings, symmetrically distributed on both sides with the central axis of the device body 1 as the reference, and maintaining the same tension and transmission path as the main yarn. Mechanically, the two test yarns 15 simulate the transmission conditions of the yarns on both sides of the device, comprehensively capturing differences in tension changes. This symmetrical installation structure expands the detection coverage, avoids the limitations of detecting a single test yarn 15, improves the comprehensiveness and accuracy of tension data, provides a reliable basis for the precise adjustment of the controller 7, and ensures that the static eliminator 13 adapts to the needs of yarns in different positions. Example

[0027] Please refer to the following: Figure 1-4 After the main structure of the device body 1 is assembled, the support legs are fixedly installed at the four corners at its bottom, with the installation direction perpendicular to the bottom surface of the device body 1, and the support legs are evenly distributed. Mechanically, the support legs provide stable support to the device body 1 through a rigid structure, isolating the device from the mounting plane. This connection structure can counteract the vibrations generated by the components during operation, preventing the device from shifting or shaking, providing a stable installation foundation for the coordinated operation of all functional components, and ensuring the stable implementation of the overall technical solution. Example

[0028] Please refer to the following: Figure 1-4After all functional components are installed, the controller 7 is fixedly mounted on the outer surface of the device body 1 in a position convenient for operation and signal transmission. It is electrically connected to the electric telescopic rod 9, pressure sensor 10, drive motor 8, and traverse yarn guiding mechanism 5 via wiring to ensure smooth signal and command transmission. Mechanically, the controller 7, as the core control unit, receives the detection signal from the pressure sensor 10, processes it, and issues adjustment commands to the electric telescopic rod 9. Simultaneously, it coordinates the operating states of the drive motor 8 and the traverse yarn guiding mechanism 5. This connection structure forms a closed-loop control system, enabling coordinated operation of all components to ensure that the static eliminator 13 is in the optimal working position, yarn transmission is stable, and ultimately, efficient yarn handling and static elimination are achieved.

[0029] The working principle of the yarn straightening device for textile machines provided by this utility model is as follows: During operation, the winding mechanism 3 is activated by the drive motor 8, driving the yarn along a preset path. The traverse yarn guiding mechanism 5 operates synchronously, guiding the yarn to move in an orderly manner to avoid deviation and accumulation. The electric telescopic rod 9, installed on the second mounting frame 4 between the first mounting frame 2 and the third mounting frame 6, has its output end passing through the second mounting frame 4 and rigidly connected to the mounting block 12. Through the extension and retraction of the electric telescopic rod 9, the static elimination rod 13 between the two mounting blocks 12 can be moved up and down flexibly, thereby adjusting the relative distance with the transmitted yarn to adapt to the static elimination requirements of different yarns. At the same time, the two symmetrical test yarns 15 between the first connecting ring 14 and the second connecting ring are transmitted synchronously with the main yarn. The pressure sensor 10 on the test rod 11 detects the tension change of the test yarn 15 in real time and transmits the detection signal to the controller 7 on the device body 1. The controller 7 precisely adjusts the extension and retraction of the electric telescopic rod 9 according to the feedback signal to ensure that the static elimination rod 13 maintains the optimal distance with the yarn, achieving efficient static elimination. The winding mechanism 3, the traverse yarn guiding mechanism 5, the static elimination adjustment structure, and the tension detection feedback structure work together to ensure smooth yarn transmission, effectively reduce various problems caused by static electricity, and comprehensively improve the quality of yarn handling and the stability and precision of subsequent weaving processes.
