Description

Technical Field

[0001] This invention relates to the field of warp knitting equipment technology, specifically to a settling device based on a warp knitting machine and the warp knitting machine itself. Background Technology

[0002] Warp knitting is a technique that uses one or more sets of parallel yarns to simultaneously form loops on all the working needles of a machine in the warp direction to create a knitted fabric. The resulting fabric is called a warp-knitted fabric. The machine that performs this type of warp knitting is called a warp knitting machine.

[0003] The function of the sinker (sometimes called a needle guide) is to: press down on the old loop during the rising period of the latch needle to prevent it from rising with the needle; and prevent the needle latch from flipping back during unwinding to ensure reliable yarn padding. For example, patent number CN106757744B discloses a double-needle bed warp knitting machine, in which the sinker motion mechanism includes a sinker, a sinker needle bed, a sinker swing arm, a sixth adjusting rod, a third connecting rod, a sinker triangular connecting rod, a sinker type 8 connecting rod, a fifth imitation U-shaped connecting rod, a fourth eccentric sleeve, and a fourth eccentric wheel. The sinker swing arm includes an integrally formed sinker secondary swing arm and a sinker main swing arm, which is rotatably sleeved on the second mounting swing shaft through a shaft hole. However, the working angle of the settling device of this warp knitting machine is usually adjusted by manually adjusting screws or replacing shims. This mechanical adjustment method has many drawbacks: First, the adjustment process is cumbersome, time-consuming and labor-intensive, which seriously affects production efficiency and the flexibility of changing products; second, the adjustment accuracy depends entirely on the operator's experience, which is difficult to control precisely and can easily lead to fabric defects and poor consistency; finally, during the high-speed operation of the warp knitting machine, vibration can easily cause the adjusted mechanism to loosen, resulting in angle drift and poor stability.

[0004] Therefore, there is an urgent need in the field for a warp knitting machine settling device that can achieve automated and precise adjustment and maintain a stable working angle over a long period of time. Summary of the Invention

[0013] Furthermore, it also includes a guiding mechanism, which includes a support plate fixedly mounted on the housing of the lifting servo motor or the mounting base and a guide groove mounted on the swing arm; a guide block is fixed on the support plate, and the guide block is inserted into the guide groove and has a clearance fit or a sliding fit with it; a displacement sensor is mounted on the mounting base, and the detection head of the displacement sensor faces the nut slide or is connected to the nut slide, for detecting the linear displacement of the nut slide.

[0014] Furthermore, the angle fine-tuning mechanism includes a support frame, a drive motor, a worm gear, and a turbine; the support frame is fixedly connected to the frame; the drive motor is fixed on the support frame, and its output shaft is connected to the worm gear; the turbine gear meshes with the worm gear; a rotating shaft is coaxially fixed on the turbine gear, and a transmission mechanism is fixedly connected through the support frame, and the transmission mechanism is hinged to the swing arm through a pin.

[0015] Furthermore, the transmission mechanism includes an eccentric wheel assembly and a connecting rod assembly; the input end of the connecting rod assembly is fixedly connected to the rotating shaft, and its output end is hinged to the eccentric wheel assembly; a hinge block is connected to the eccentric wheel assembly, and one end of the hinge block is hinged to the swing arm.

[0019] Warp knitting machine, including the aforementioned settling device based on the warp knitting machine.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] 1. Achieving Automated Precise Adjustment and Intelligent Control: This invention utilizes a lifting servo motor to drive a ball screw, forming the core angle adjustment mechanism and replacing the traditional manual mechanical adjustment method. This allows the initial angle of the sinker to be automatically adjusted automatically and digitally with a single click according to different fabric process requirements, greatly improving the intelligence level and production efficiency of the warp knitting machine.

[0022] 2. Significantly Improved Adjustment Precision and Fabric Quality: This invention innovatively employs a two-tiered adjustment mode, combining an angle adjustment mechanism and an angle fine-tuning mechanism. The angle adjustment mechanism performs rapid, wide-range coarse adjustments, while the angle fine-tuning mechanism provides precise, small-range adjustments. This design fundamentally overcomes the shortcomings of insufficient precision in a single adjustment mechanism, ensuring extremely high accuracy in the final working position of the sinker, thereby effectively reducing weaving defects and significantly improving fabric quality and consistency.

[0023] 3. Possesses self-locking function and excellent operational stability: The angle fine-tuning mechanism of this invention adopts a "worm-worm gear" transmission pair. The worm gear mechanism naturally possesses a reverse self-locking characteristic, meaning that the worm gear cannot drive the worm in the reverse direction. This characteristic ensures that once the fine-tuning is completed, the position of the settling actuator is reliably locked, effectively preventing angle drift caused by vibration even under the high-speed, long-term vibration environment of the warp knitting machine, thus guaranteeing continuous stability and safety in production.

[0024] 4. Excellent transmission rigidity and stability: The guide mechanism (support plate, guide block, and guide groove) in the drive assembly of this invention provides solid guidance and support for the movement of the swing arm, effectively counteracting the radial force borne by the ball screw and preventing wobbling and jamming of the nut slide and the swing arm. This ensures a smooth and stable angle adjustment process, improving transmission rigidity and the service life of the mechanism.

[0025] 5. Expanded process adaptability of warp knitting machines: Because the working angle of the sinker plate can be conveniently and accurately adjusted online, a single warp knitting machine can quickly adapt to more types of yarns and fabric structures (such as elastic fabrics, heavy fabrics, ultra-thin fabrics, etc.), realizing multi-purpose use, enhancing the competitiveness of the equipment in the market, and reducing the equipment investment costs of production enterprises.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Reference Figures 1-6 As shown, a preferred embodiment of the present invention, based on a settling device for a warp knitting machine, mainly includes a frame 1, a first swing shaft 2, a second swing shaft 3, a settling actuator 8, a linkage mechanism 9, an angle adjustment mechanism, and an angle fine-tuning mechanism 6. The frame 1 serves as the supporting structure for the entire device. Components such as the first swing shaft 2 and the second swing shaft 3 are rotatably mounted on the frame 1.

[0041] A settling actuator 8, fixedly connected to the first swing shaft 2, is used to perform settling actions. This settling actuator includes several main settling arms and auxiliary settling arms fixedly mounted on the first swing shaft. These main and auxiliary settling arms are spaced apart along the axial direction of the first swing shaft, forming a stable support frame. Settling plate seats 83 are mounted on the main settling arms 81 and 82, and settling needles 84, which perform the final circular motion, are mounted on the settling plate seats 83. The auxiliary settling arm 82 is rotatably connected to the linkage mechanism 9 via a pin.

[0042] The linkage mechanism 9 is fixedly connected to the second swing shaft 3 and drively connected to the settling actuator 8; it includes a first adapter rod 91, a second adapter rod 92, and a settling disengagement swing arm 93, which are hinged in sequence. The settling disengagement swing arm 93 is fixedly connected to the second swing shaft 3. The end of the first adapter rod 91 away from the second adapter rod 92 is hinged to the settling auxiliary arm 82 by a pin. When the second swing shaft 3 rotates, the linkage mechanism drives the settling auxiliary arm 82 and the entire settling actuator 8 to swing around the first swing shaft 2, changing the initial angle of the settling needle 84.

[0043] An angle adjustment mechanism, which is the core of the automated coarse adjustment, includes a drive component 4 and a swing component 5; the first end of the swing component 5 is fixedly connected to the second swing shaft 3, and the second end is connected to the output end of the drive component 4; the drive component 4 is used to drive the swing component 5 to swing, so as to drive the second swing shaft 3 to rotate, thereby adjusting the initial angle of the settling actuator 8 through the linkage mechanism 9;

[0044] An angle fine-tuning mechanism 6, mounted on the frame 1 and connected to the swing assembly 5, is used to fine-tune and lock the swing angle of the swing assembly 5. This establishes a dual adjustment mechanism of "coarse angle adjustment + fine-tuning and locking." The angle adjustment mechanism enables a wide range of automated and rapid adjustments to the initial angle of the sinker, meeting the requirements of product change processes. The angle fine-tuning mechanism 6 performs fine calibration and final locking based on the coarse adjustment, ensuring ultimate accuracy and vibration resistance stability of the working position. This collaborative design fundamentally solves the problems of time-consuming and labor-intensive adjustments, poor accuracy, and easy loosening in traditional equipment, achieving automation and precision in the warp knitting machine sinking process.

[0045] As a preferred embodiment of the present invention, it may also have the following additional technical features: the swing assembly 5 includes a swing plate 51, an adjusting plate 52, and a swing arm 53; the swing plate 51 is fixed to the second swing shaft 3; one end of the adjusting plate 52 is hinged to the swing plate 51, and the other end is hinged to the first end of the swing arm 53; the second end of the swing arm 53 is connected to the output end of the drive assembly 4. Thus, efficient transmission of motion and force is achieved, smoothly converting the linear motion of the drive assembly 4 into the rotational motion of the second swing shaft 3.

[0046] In this embodiment, the drive assembly 4 includes a mounting base 44 fixedly mounted on the frame, a lifting servo motor 41, a ball screw 42, and a nut slide 43. The lifting servo motor is rotatably mounted on the mounting base 44, and its output shaft is coaxially connected to the ball screw 42. The nut slide 43 is sleeved on the ball screw 42 and threadedly engaged with it. The second end of the swing arm 53 is fixedly connected to the nut slide 43. Thus, during operation, the lifting servo motor 41 receives instructions from the control system to rotate, driving the ball screw 42 to rotate, thereby causing the nut slide 43 to move linearly along the axial direction of the ball screw 42. The movement of the nut slide 43 is converted into the swing of the swing plate 51 through the swing arm 53 and the adjusting plate 52, ultimately driving the second swing shaft 3 to rotate, thereby achieving coarse adjustment of the initial angle of the entire settling actuator. Furthermore, the ball screw 42 has low friction, enabling it to respond quickly and accurately to commands from the control system; and the drive assembly is powerful and has good self-locking properties (in conjunction with the servo motor brake), reliably maintaining the position after coarse adjustment, providing a stable foundation for subsequent fine adjustments.

[0047] Simultaneously, due to the movement of the swing arm 53, the lifting servo motor 41 can rotate adaptively due to the presence of the connecting piece 641, so that the swing arm 53 will also swing to a certain extent during the movement. And through the drive of the adjusting plate 52, the swing plate 51 can make corresponding precise movements, thereby intelligently controlling the initial working angle of the settling actuator 8.

[0048] To improve the stability and accuracy of the coarse adjustment process, this embodiment also includes a guiding mechanism. The guiding mechanism includes a support plate 45 fixedly mounted on the housing of the lifting servo motor 41 and a guide groove 531 mounted on the swing arm 53. A guide block 451 is fixed on the support plate 45, and the guide block 451 is precisely inserted into the guide groove 531 and slides within it. This ensures that the swing arm 53 can only move smoothly in a preset direction without any wobbling. Furthermore, this structure provides excellent guidance for the movement of the swing arm 53 and better supports and limits the nut slide 43, further ensuring nut engagement between the nut slide 43 and the ball screw 42 when the ball screw 42 rotates. This allows the ball screw 42 to better drive the movement of the nut slide 43 and the swing arm 53.

[0049] In this embodiment, a displacement sensor 7 is installed on the mounting base 44. The detection head of the displacement sensor 7 faces the nut slide 43 and is used to detect the linear displacement of the nut slide 43. This displacement can be converted into the current angle value by the control system, realizing digital display and closed-loop control of the angle. That is, by detecting the precise displacement of the nut slide 43, the real-time angle of the settling plate can be calculated indirectly and accurately. This realizes the digital monitoring and feedback of the working angle, which not only facilitates the direct display and setting of the angle value on the operation panel, but also provides a key data interface for a fully automatic and intelligent process management system, making it an important part of realizing a "smart factory".

[0050] In this embodiment, the angle fine-tuning mechanism 6 includes a support frame 67, a drive motor 61, a worm gear 62, and a turbine 63. The support frame 67 is fixedly connected to the frame 1. The drive motor 61 is fixed on the support frame 67, and its output shaft is connected to the worm gear 62. The turbine 63 meshes with the worm gear 62 to form a transmission pair with a reverse self-locking function. A rotating shaft 631 is coaxially fixed to the turbine 63. The rotating shaft 631 is rotatably connected to the support frame 67. To ensure the stability of the rotation of the rotating shaft 631, a bearing is provided at the connection between the rotating shaft 631 and the support frame. This bearing is fixedly connected to the inner wall of the support frame. The rotating shaft 631 is hinged to the swing arm 53 through a transmission mechanism.

[0051] The rotational motion of the turbine 63 is transmitted to the swing arm 53 through a transmission mechanism. This transmission mechanism may include an eccentric wheel assembly 64 and a connecting rod assembly 65. Specifically, a connecting rod assembly 65 may be connected to one end of the rotating shaft 631, and the other end of the connecting rod assembly 65 is hinged to the eccentric wheel assembly 64. The other end of the eccentric wheel assembly 64 is finally hinged to the swing arm 53 through a hinge block 66; the hinge block 66 and one end of the swing arm 53 are both hinged together by a pin.

[0052] The eccentric wheel assembly 64 includes a connector 641 fixedly connected to the hinge block 66, a rotating block 642 fixedly connected to the connector 641, an eccentric wheel 643 rotatably sleeved inside the rotating block 642, a second rotating shaft 644 fixedly mounted on the eccentric wheel 643, and the second rotating shaft 644 rotatably mounted on the mounting base 44; the connecting rod assembly 65 includes a first connecting rod 651 fixedly connected to the second rotating shaft 644, a second connecting rod 652 hinged to the first connecting rod 651, a third connecting rod 653 hinged to the other end of the second connecting rod 652, and the other end of the third connecting rod 653 fixedly connected to the first rotating shaft 631.

[0053] When fine-tuning is required, the drive motor 61 is started, which drives the turbine 63 to rotate slowly via the worm gear 62. This rotation, in turn, drives the rotating shaft 644 via the connecting rod assembly 65, thereby rotating the eccentric wheel 643. Based on the principle of the eccentric wheel, the connecting piece 641 can be slightly moved via the rotating block 642, causing the swing arm 53 to swing slightly. Correspondingly, the lifting servo motor 41 can rotate slightly. Then, driven by the swing arm 53, the adjusting plate 52 and the swing plate 51 can move slightly, ultimately causing the second swing shaft 3 to rotate slightly, achieving fine adjustment of the working angle of the entire settling actuator. Due to the self-locking characteristic of the worm gear, the position of the entire mechanism is reliably locked after fine-tuning, providing strong vibration resistance.

[0054] The connector 641 is an angle offset sensor, which is electrically connected to the PLC control system. After coarse adjustment, the PLC control system generates a precise fine-tuning command based on the minute deviation between the angle offset sensor and the target angle. The drive motor 61 starts according to this command, performing precise pulse rotation to drive the worm gear 62 and the turbine 63. The minute rotation of the turbine 63, through the eccentric wheel assembly 64 and the connecting rod assembly 65, is ultimately converted into a fine compensation adjustment of the position of the swing arm 53, completely eliminating the residual angle deviation after coarse adjustment. Throughout the fine-tuning process, the angle offset sensor continuously provides feedback, forming a high-precision closed-loop control loop until the angle value stabilizes at the target value. After the fine-tuning action stops, the inherent reverse self-locking characteristic of the worm gear pair firmly locks the entire system in the finally confirmed position. Furthermore, the angle offset sensor can be a commercially available product.

[0055] Working principle: When it is necessary to adjust the working angle of the sinker 84, firstly, the system is initialized and coarsely adjusted: the angle adjustment mechanism works, and the operator inputs the target angle value on the control panel of the warp knitting machine. The control system calculates the target displacement that the nut slide 43 needs to move according to the preset algorithm (such as the correspondence between displacement and angle).

[0056] The control system sends a command to the lifting servo motor 41 to start it. The lifting servo motor 41 drives the ball screw 42 to rotate, which in turn drives the nut slide 43 to move linearly.

[0057] The nut slide 43 pushes the swing arm 53 to move upward. The swing arm 53 moves smoothly under the constraint of the guide block 451, so that the movement of the swing arm 53 is transmitted to the swing plate 51 through the adjusting plate 52, forcing the second swing shaft 3 to rotate by an angle.

[0058] The rotation of the second swing shaft 3 is transmitted to the settling auxiliary arm 82 through the linkage mechanism 9 (settling disengagement swing arm 93-second adapter rod 92-first adapter rod 91), which drives the entire settling actuator 8 to swing around the first swing shaft 2, causing the settling auxiliary arm 82 to deviate from the center of the equipment, thereby causing the settling needle 84 to move quickly to the vicinity of the target angle.

[0059] During this process, the displacement sensor 7 provides real-time feedback on the actual position of the nut slide 43, forming a closed-loop control to ensure accurate coarse adjustment positioning.

[0060] Second, fine calibration and locking: After coarse adjustment, the control system can activate the angle fine adjustment mechanism 6 based on more precise sensor feedback (such as a sensor that can directly measure the angle, or by judging through the effect of the fabric sample) or a preset fine adjustment program.

[0061] After receiving the fine-tuning command, the drive motor 61 rotates slowly, driving the worm gear 62 to rotate. The worm gear 62 drives the turbine 63 to rotate slightly. The rotation of the turbine 63 is converted into extremely small linear motion of the articulated block 66 through the transmission mechanism (eccentric wheel assembly 64 and connecting rod assembly 65).

[0062] The minute movement of the hinge block 66 creates a subtle "push or pull" effect on the swing arm 53. Since the coarse adjustment mechanism is fixed at this time, this minute force is sufficient to perform a final, micron-level fine calibration of the angle of the second swing axis 3, so that the sinking needle 84 reaches the final precise target position.

[0063] Once the fine-tuning action stops, the entire transmission chain is firmly locked due to the inherent reverse self-locking characteristic of the worm gear pair. Even during the subsequent high-speed operation of the warp knitting machine, which reaches thousands of revolutions per minute, the strong vibrations cannot cause the turbine 63 to reverse drive the worm 62, thus ensuring the ultra-strong stability of the settling working angle.

[0064] The control system commands the lifting servo motor 41 to rotate, which drives the swing arm 53 to move via the ball screw 42 and nut pair. This movement, via the swing assembly 5, drives the second swing shaft 3 to rotate, and then, through the linkage mechanism, drives the settling actuator 8 to swing to near the target angle. Subsequently, the angle fine-tuning mechanism 6 is activated: the drive motor 61 operates, and through the worm gear pair and transmission mechanism, the position of the swing arm 53 is precisely adjusted at the micrometer level, ensuring the settling needle 84 reaches the accurate target angle. After fine-tuning, the worm gear pair self-locks, firmly fixing the position. The entire adjustment process is fast, precise, and stable.

[0065] Finally, the present invention also provides a warp knitting machine equipped with the settling device based on the warp knitting machine described in any of the above embodiments. This warp knitting machine thus possesses automated, high-precision, and highly stable settling adjustment capabilities.
