Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine comb technology, specifically to a rapid autonomous reset device for the lateral movement of warp knitting machine combs. Background Technology

[0002] To meet the needs of efficient and precise yarn combing and to ensure the continuity and quality of yarn combing, the warp knitting machine needs to quickly and stably reset the comb bars after they move laterally. This requires the use of a special rapid self-resetting device.

[0003] For example, Chinese Patent Publication No. CN221760112U discloses a warp knitting machine guide bar transverse movement and reset device. This existing device uses the elasticity of a spring to drive a reset rod to tighten the transverse frame. After the guide bar above the transverse frame has transversely moved, the spring elasticity can automatically reset the guide bar, thus achieving guide bar reset. However, this existing device has many drawbacks in practical applications: First, the spacing between multiple guide bars is relatively fixed in the existing device, making it difficult to flexibly adjust according to yarn type and process requirements, which greatly reduces the adaptability of the device and the diversity of yarn combing. Second, during the guide bar reset process, due to the large impact and vibration generated during combing, the reset rod is difficult to return to the centered position. This not only affects the subsequent combing effect on the yarn but may also damage the device structure. Finally, the connection between the reset rod and the transverse frame in the existing device is not stable enough and is easily loosened by vibration and impact, resulting in poor reset effect or device malfunction. Utility Model Content

[0004] The purpose of this invention is to provide a rapid self-reset device for the transverse movement of the guide bars of a warp knitting machine. This device can conveniently adjust the distance between multiple guide bars and enable the transverse movement frame to return to its initial position under the action of a torsion spring, thus achieving rapid self-reset.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid self-resetting device for the transverse movement of the guide bars of a warp knitting machine, comprising a base plate and a frame at its top, wherein the tail of the warp knitting machine is provided in the frame, wherein multiple sets of guide bars for combing the yarn are provided in the frame, wherein an adjustment mechanism for adjusting the distance between the multiple sets of guide bars is provided in the frame, and wherein a self-resetting mechanism for rapid self-resetting after the guide bars have transversely moved is also provided in the frame.

[0009] Preferably, the mounting frame is further provided with a guide rod, the first movable frame has a through hole for the guide rod to pass through, and a damping spring is provided outside the guide rod to slow down the movement speed of the first movable frame.

[0010] Preferably, the multi-stage reset assembly further includes an annular sleeve disposed in the connecting sleeve, and the annular sleeve is provided with a torsion spring that enables the reset rod to reset automatically after rotation.

[0016] 1. The rapid self-resetting device for the lateral movement of the guide bars on this warp knitting machine allows for convenient adjustment of the distance between multiple sets of guide bars via a sliding connecting frame, adapting to different yarn types and knitting requirements. Once adjusted, the triangular-tooth self-locking bolts ensure a secure lock on the connecting frame, preventing the guide bars from falling off during knitting and thus guaranteeing the continuity and stability of the knitting process. This flexible adjustment capability enables the device to adapt to various yarn knitting scenarios, improving the overall knitting effect.

[0017] 2. The rapid self-resetting device for the lateral movement of the warp knitting machine's guide bar enhances structural stability through a combination of mounting bolts, anti-loosening washers, and mounting nuts, ensuring reliable connection of the lateral movement frame during lateral movement.

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0029] Example 1: Please refer to Figures 1-7 This utility model provides a technical solution: a rapid self-resetting device for the transverse movement of the guide bars of a warp knitting machine, including a base plate 1 and a frame 2 on top of it. The frame 2 is provided with the tail of the warp knitting machine 3. The frame 2 is provided with multiple sets of guide bars 4 for combing the yarn. The frame 2 is provided with an adjustment mechanism 5 for adjusting the distance between the multiple sets of guide bars 4. The frame 2 is also provided with a self-resetting mechanism 6 for rapid self-resetting after the guide bars 4 transverse movement.

[0030] The adjustment mechanism 5 includes a transverse frame 51, with the comb bars 4 movably mounted outside the transverse frame 51. It provides a flexible adjustment function for the spacing of the comb bars 4, allowing for optimization of the combing effect and improvement of product quality according to yarn type and process requirements.

[0031] The self-resetting mechanism 6 includes a reset rod 61 connected to the transverse frame 51. A multi-stage reset assembly 61a is provided outside the reset rod 61 to enable rapid reset after transverse movement. This achieves rapid and stable reset of the comb 4 after transverse movement, reducing downtime and improving production efficiency.

[0032] Furthermore, the multi-stage reset assembly 61a includes two sets of mounting frames 611 disposed in the base plate 1. Two sets of first movable frames 612 are movably disposed within the mounting frames 611. A connecting plate 613 is rotatably disposed within each first movable frame 612. A second movable frame 614 is rotatably disposed on the side of the connecting plate 613 away from the first movable frame 612. A connecting sleeve 615 is disposed between the two sets of second movable frames 614, and the reset rod 61 is disposed within the connecting sleeve 615. This allows the reset rod 61 to remain in a centered position after lateral movement.

[0033] Furthermore, a guide rod 616 is provided in the mounting frame 611, and a through hole is provided in the first movable frame 612 for the guide rod 616 to pass through. A damping spring 617 is provided outside the guide rod 616 to slow down the movement speed of the first movable frame 612. By slowing down the movement speed, the impact and vibration during the reset process are reduced, protecting the device structure and extending its service life.

[0034] Furthermore, the multi-stage reset assembly 61a also includes an annular sleeve 618 disposed in the connecting sleeve 615, and a torsion spring 619 disposed in the annular sleeve 618 to enable the reset rod 61 to automatically reset after rotation. The introduction of the torsion spring 619 provides additional reset force, ensuring stable reset of the reset rod 61 at different angles and improving reset accuracy.

[0035] Furthermore, the adjustment mechanism 5 also includes a connecting frame 52 disposed outside the comb 4, with a connecting hole 53 in the connecting frame 52, and a triangular thread self-locking bolt 54 threaded into the connecting hole 53. The locking function of the triangular thread self-locking bolt 54 ensures the stable position of the comb 4 after adjustment and prevents positional displacement during the combing process.

[0036] Furthermore, the transverse frame 51 has mounting holes 55 through which the triangular self-locking bolts 54 pass. This enables precise adjustment of the comb bar 4 position, simplifying the adjustment process and improving the accuracy and efficiency of the adjustment.

[0037] Example 2: Please refer to Figures 8-9 Furthermore, in conjunction with Embodiment 1, an anti-loosening mechanism 7 is provided outside the transverse frame 51 and is securely connected to the reset rod 61. The anti-loosening mechanism 7 includes a connecting frame 71 disposed outside the transverse frame 51, with a mounting bolt 72 threadedly connected to the connecting frame 71, and a mounting nut 73 disposed outside the mounting bolt 72. The introduction of the anti-loosening mechanism 7 effectively prevents the reset rod 61 from loosening during long-term use, ensuring the stability and reliability of the device.

[0038] Furthermore, two sets of connecting brackets 71 are provided, symmetrically arranged outside the transverse frame 51. Anti-loosening washers 74 are provided between the mounting bolts 72 and the mounting nuts 73 to ensure a tight fit. This further improves the connection stability between the transverse frame 51 and the reset rod 61.

[0039] In actual operation, to ensure the yarn combing effect, the distance between multiple sets of comb bars can be adjusted. The specific operation is as follows:

[0040] First, the position of the comb 4 is changed by sliding the connecting frame 52. After adjustment, the triangular self-locking bolt 54 is aligned with the connecting hole 53 and rotated so that it passes through the connecting hole 53 and the mounting hole 55, locking the connecting frame 52 to prevent the comb 4 from falling off the transverse frame 51 during combing.

[0041] Next, to prevent the transverse frame 51 from becoming detached from the reset rod 61 during the transverse movement, which would make reset difficult, additional fixing is required. Insert the mounting bolt 72 through the connecting frame 71, the transverse frame 51, and the reset rod 61, then install the anti-loosening washer 74 outside the mounting nut 73, and rotate the mounting nut 73 to ensure a stable connection.

[0042] After installation and adjustment, the guide bar 4 begins to comb the yarn. During the lateral movement, the lateral frame 51 returns to its initial position under the action of the torsion spring 619. If the lateral frame 51 wobbles significantly, the connecting sleeve 615 will move accordingly, causing the connecting plate 613 to rotate, and the first movable frame 612 to slide on the guide rod 616. After the moving force disappears, the damping spring 617 returns both sets of first movable frames 612 to their initial positions, and the connecting sleeve 615 returns to the center, ensuring that the guide bar 4 can continue to effectively comb the yarn.

[0043] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
