[0002] Jacquard fabrics, due to their complex patterns and textures, are widely used in high-end clothing, home décor, and other fields. Traditional jacquard looms use a heddle-raising device to control the raising and lowering of warp yarns to form patterns. With the increasing market demand for jacquard fabrics, higher requirements are placed on the precision, speed, and reliability of the heddle-raising device; therefore, a heddle-raising device specifically designed for jacquard fabrics is needed.

[0003] A search revealed Chinese Patent Publication No. CN213113696U, which discloses a heddle-lifting device for jacquard fabric production, belonging to the technical field of heddle-lifting devices. The device includes a housing, with a groove A embedded in the inner side of the housing. A slider A is slidably connected to the right side of the groove A. A heddle frame A is welded to the right side of the slider A. A roller A is detachably connected to the top of the housing, and a roller B is fixedly installed to the right side of the roller A. A rotating shaft is loosely connected to the top right side of the housing, and a crossbar is rotatably connected to the right side of the rotating shaft. A pull plate is welded to the right side of the crossbar. A heddle frame B is fixedly installed on one side of the heddle frame A, and a slider B is welded to the left side of the heddle frame B. A groove B is slidably connected to the left side of the slider B. This invention, by installing the groove A, groove B, slider A, and slider B, prevents the heddle frames A and B from shifting during vertical movement, improving work efficiency and demonstrating good practicality.

[0004] In the aforementioned utility model, the installation of sliding grooves and sliders can prevent the heald frame from shifting during vertical movement, thereby improving work efficiency and demonstrating good practicality.

The inner wall of the connecting plate 16 is fixedly connected to a connecting shaft 17. The outer wall of the connecting shaft 17 is rotatably connected to a heald frame 18. The outer wall of the heald frame 18 is slidably connected to the inner wall of the limiting seat 2.

[0053] Specifically, the eccentric wheel 1004 can drive the rotating shaft 11 to rotate, the rotating shaft 11 can drive the rotating plate 12 to rotate, the rotating plate 12 can drive the rotating shaft 13 to rotate, and the rotating shaft 13 can drive the first rotating plate 14 to rotate.

[0054] Reference Figure 4 and Figure 5 The first rotating plate 14 is fixedly connected to a rotating shaft 19. The outer wall of the rotating shaft 19 is rotatably connected to a connecting rod 20. The inner wall of the connecting rod 20 is rotatably connected to a rotating shaft 21. The outer wall of the rotating shaft 21 is fixedly connected to a second rotating plate 22. The outer wall of the second rotating plate 22 is rotatably connected to the inside of the support frame 3. The inner wall of the second rotating plate 22 is fixedly connected to a support shaft 23. The outer wall of the support shaft 23 is rotatably connected to a support rod 24. The inner wall of the support rod 24 is fixedly connected to a support shaft 25. The outer wall of the support shaft 25 is rotatably connected to a heald frame 26. The outer wall of the heald frame 26 is slidably connected to the inside of the limiting seat 2.

[0055] Specifically, the rotation of the first rotating plate 14 can drive the first rotating shaft 19 to move, the first rotating shaft 19 can drive the connecting rod 20 to rotate, the connecting rod 20 can drive the second rotating shaft 21 to move, the second rotating shaft 21 can drive the second rotating plate 22 to rotate inside the support frame 3, the second rotating plate 22 can drive the first supporting shaft 23 to move, the first supporting shaft 23 can drive the supporting rod 24 to rotate, the supporting rod 24 can drive the second supporting shaft 25 to rotate, and the second supporting shaft 25 can drive the second heald frame 26 to reciprocate inside the limit seat 2, thus cooperating with the first heald frame 18 to complete the heald lifting operation.

[0056] Working principle: When the lifting device is needed, first install the device in a suitable position. Drive the support frame 3 to slide on the outer wall of the limiting seat 2. After the support frame 3 slides to the suitable position, rotate the rotating block 8 to drive the fixed shaft 7 to rotate inside the locking post 5, thereby driving the sliding piece 6 to slide inside the support frame 3. At the same time, drive the locking post 5 to slide in the limiting groove 4 opened inside the limiting seat 2. Then, the spring 9 can limit the locking post 5 through its rebound action, thereby fixing the support frame 3 on the limiting seat 2, completing the adjustment and installation of the device height, and facilitating the disassembly and maintenance of the device.

[0057] When the fabric needs to be heddled, the motor 1001 is started to drive the roller 1002 to rotate, which in turn drives the belt 1003 to drive the eccentric wheel 1004 to rotate. As the eccentric wheel 1004 rotates, it drives the rotating plate 12 to rotate on the outer wall of the rotating shaft 11, which in turn drives the rotating plate 12 to rotate on the outer wall of the rotating shaft 13. Simultaneously, it drives the first rotating plate 14 to reciprocate inside the support frame 3, which in turn drives the connecting plate 16 to rotate on the outer wall of the connecting shaft 15. At the same time, the connecting shaft 17 drives the heddle frame 18 to reciprocate up and down inside the limiting seat 2. Simultaneously, the first rotating plate 14 reciprocates... The connecting rod 20 reciprocates on the outer wall of the rotating shaft 19, and simultaneously rotates on the outer wall of the rotating shaft 21. This causes the second rotating plate 22 to reciprocate inside the support frame 3, while simultaneously rotating the support rod 24 on the outer wall of the support shaft 23. This causes the support shaft 25 to rotate inside the heald frame 26, and simultaneously causes the heald frame 26 to reciprocate inside the limiting seat 2. This achieves vertical up-and-down movement of the heald frame 18 and the heald frame 26, thus completing the heald lifting and improving the heald lifting efficiency. This device not only allows for fine-tuning of the device's height and rapid installation, but also improves the heald lifting efficiency.
