Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology, and in particular to a yarn anti-jump mechanism for warp knitting machines. Background Technology

[0002] The prior art discloses a yarn anti-jump mechanism for a warp knitting machine, application number CN202010735508.1. This mechanism includes symmetrically arranged rotating supports on both sides of the warp knitting machine. The top of the rotating supports is rotatably connected to the warp knitting machine via a first rotating shaft. A placement groove, shaped like a "7", is provided on the outer side of the rotating supports. This groove includes interconnected horizontal and vertical grooves. The vertical groove runs in the same direction as the length of the rotating supports. The angle between the horizontal and vertical grooves is no greater than 90°. A stop bar is placed at the bottom of the vertical groove. Pin plates are provided on both sides of the warp knitting machine. One end of each pin plate is rotatably connected to the warp knitting machine via a second rotating shaft, and the other end has a pin hole A. At least two pin holes B, matching pin holes A, are provided on the rotating supports. Pin holes A and any one of pin holes B are fixed by pins. When this invention is installed on the warp knitting machine, the stop bar in the placement groove can block the yarn during operation, thereby preventing the yarn from jumping outwards.

[0003] In the aforementioned authorized patent, by cooperating the pin hole A with different pin holes B, the swing angle of the rotating bracket can be adjusted according to the performance of the yarn. However, the swing angle of the rotating bracket is only three, but the yarn has various specifications, making it inconvenient to fine-tune the angle of the rotating bracket, resulting in poor anti-jumping effect on the yarn. To solve the above problems, this application proposes a yarn anti-jumping mechanism for a warp knitting machine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a yarn anti-jump mechanism for warp knitting machines. By combining a yarn anti-jump wheel and a limiting groove, the yarn can be limited. The angle of the rotating bracket can be adjusted by a hydraulic rod, and the positions of the connecting rod and the yarn anti-jump wheel can be finely adjusted to meet the needs of different yarn applications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A yarn anti-jump mechanism for a warp knitting machine includes a warp knitting machine body. Fixed T-shaped rods are fixedly connected to the front and rear ends of the warp knitting machine body. A rotating bracket is rotatably connected to the outer wall of each fixed T-shaped rod. Two rotating brackets share a connecting rod. Fixed blocks are fixedly connected to the front and rear ends of each connecting rod. Multiple yarn anti-jump wheels are fixedly connected to the outer wall of the connecting rod. A first T-shaped block is fixedly connected to the outer wall of each rotating bracket. A deflecting rod is rotatably connected to each first T-shaped block. A second T-shaped rod rotatably connected to each deflecting rod passes through it. Two second T-shaped rods are fixedly connected to a lifting plate. An adjustment mechanism is provided between the warp knitting machine body and the lifting plate.

[0007] Preferably, the adjusting mechanism includes two sliding rods fixedly connected to the warp knitting machine body, both sliding rods passing through and slidably connected to the lifting plate, and a hydraulic rod fixedly connected to the top of the lifting plate, the hydraulic rod being fixedly connected to the warp knitting machine body.

[0008] Preferably, each of the rotating brackets is provided with an L-shaped groove, and the two ends of the connecting rod are respectively placed in the L-shaped groove and abut against the inner wall of the L-shaped groove.

[0009] Preferably, the yarn anti-jumping wheel has a limiting groove.

[0010] Preferably, the warp knitting machine body has a through opening, both sliding rods are fixedly connected to the inner wall of the through opening, and the lifting plate is located inside the through opening and slidably connected to its inner wall.

[0011] Preferably, the inner wall of the limiting groove is coated with a wear-resistant layer, and the wear-resistant layer is made of a high wear-resistant ceramic coating.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The lifting plate can be adjusted by sliding on two sliding rods using hydraulic rods, thereby adjusting the height of the lifting plate. The lifting plate's movement drives two deflection rods, which in turn cause the rotating brackets to swing, allowing the two rotating brackets to rotate around a fixed T-shaped rod as the center of rotation. This enables the adjustment of the angle of the rotating brackets, and consequently, the position of the connecting rod. The angle of the rotating brackets can be adjusted according to the properties of the yarn.

[0014] 2. When the warp knitting machine is working, the yarn is blocked by the limiting groove on the yarn anti-jump wheel, which can greatly reduce the jumping amplitude, thereby improving the quality of the product and reducing the chance of weaving interruption. In addition, the wear-resistant layer set on the limiting groove can extend the service life of the yarn anti-jump wheel.

[0015] In summary, by combining the yarn anti-jump wheel and the limiting groove, the yarn can be limited. The hydraulic rod can be used to adjust the swing angle of the rotating bracket and fine-tune the position of the connecting rod and the yarn anti-jump wheel to meet the needs of different yarn applications.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-3 A yarn anti-jump mechanism for a warp knitting machine includes a warp knitting machine body 1. Fixed T-shaped rods 2 are fixedly connected to the front and rear ends of the warp knitting machine body 1. A rotating bracket 3, rotatably connected to the outer wall of each fixed T-shaped rod 2, is fitted onto the outer wall of each fixed T-shaped rod 2. A connecting rod 5 is mounted on both rotating brackets 3. An L-shaped groove 4 is opened on each rotating bracket 3. The two ends of the connecting rod 5 are respectively placed inside the L-shaped groove 4 and abut against the inner wall of the L-shaped groove 4. By placing the connecting rod 5 into the L-shaped groove 4, the conveyed yarn is limited to prevent yarn jumps. Furthermore, the connecting rod 5 and the yarn anti-jump wheel 7 are relatively heavy and will not move arbitrarily.

[0022] Both the front and rear ends of the connecting rod 5 are fixedly connected to fixing blocks 6. Multiple yarn anti-jump wheels 7 are fixedly connected to the outer wall of the connecting rod 5. Limiting grooves 8 are opened on the yarn anti-jump wheels 7. The yarn moves in the limiting grooves 8 and is limited by the yarn anti-jump wheels 7. The inner wall of the limiting grooves 8 is coated with a wear-resistant layer. The wear-resistant layer is made of a high wear-resistant ceramic coating, which can ensure the wear resistance of the yarn anti-jump wheels 7 when they are in contact with the yarn for a long time, thus extending the service life of the yarn anti-jump wheels 7.

[0023] Each rotating bracket 3 has a first T-shaped block 9 fixedly connected to its outer wall. Each first T-shaped block 9 is rotatably connected to a deflection rod 10. Each deflection rod 10 is provided with a second T-shaped rod 11 rotatably connected to it. The two second T-shaped rods 11 are fixedly connected to a lifting plate 12. An adjustment mechanism is provided between the warp knitting machine body 1 and the lifting plate 12. The lifting plate 12 can be adjusted by raising and lowering through the adjustment mechanism.

[0024] The adjustment mechanism includes two sliding rods 14 fixedly connected to the warp knitting machine body 1. Both sliding rods 14 pass through the lifting plate 12 and are slidably connected to it. A hydraulic rod 15 is fixedly connected to the top of the lifting plate 12. The hydraulic rod 15 is fixedly connected to the warp knitting machine body 1. A through-hole 13 is provided on the warp knitting machine body 1. Both sliding rods 14 are fixedly connected to the inner wall of the through-hole 13. The lifting plate 12 is located inside the through-hole 13 and is slidably connected to its inner wall. By moving the lifting plate 12 up and down within the through-hole 13, the rotating bracket 3 swings around the fixed T-shaped rod 2 as the rotation center, thereby adjusting the position of the connecting rod 5. The angle of the rotating bracket 3 can be adjusted according to the properties of the yarn.

[0025] In this invention, the hydraulic rod 15 is activated, which allows the lifting plate 12 to slide on the two sliding rods 14, thereby adjusting the height of the lifting plate 12. The lifting plate 12 moves up and down, causing the two deflection rods 10 to swing the rotating bracket 3, making the two rotating brackets 3 rotate around the fixed T-shaped rod 2 as the rotation center. This allows for angle adjustment of the rotating bracket 3, which in turn adjusts the position of the connecting rod 5. The angle of the rotating bracket 3 can be adjusted according to the yarn properties. When the warp knitting machine is working, the yarn is blocked by the limiting groove 8 on the yarn anti-jump wheel 7, which can greatly reduce the jumping amplitude, thereby improving product quality and reducing the probability of weaving interruption. The wear-resistant layer set on the limiting groove 8 can extend the service life of the yarn anti-jump wheel 7. After the connecting rod 5 has been used for a long time, the fixing blocks 6 set on both sides of the connecting rod 5 can prevent the connecting rod 5 from slipping out of the L-shaped groove 4. In addition, the connecting rod 5 and the multiple yarn anti-jump wheels 7 are relatively heavy, which can ensure the stability of the connecting rod 5 and the multiple yarn anti-jump wheels 7 when in contact with the yarn.

[0026] This invention solves the problem that existing technologies only allow for three swing angles of the rotating bracket, but the yarn comes in various specifications, making it inconvenient to fine-tune the angle of the rotating bracket and resulting in poor anti-jumping effect on the yarn. By setting up yarn anti-jump wheels and limiting grooves, and by using hydraulic rods to adjust the swing angle of the rotating bracket, this invention addresses the issue that existing technologies only allow for three swing angles of the rotating bracket, but the yarn comes in various specifications, making it inconvenient to fine-tune the angle of the rotating bracket and resulting in poor anti-jumping effect on the yarn.
