Description

Technical Field

[0001] This utility model relates to the technical field of thread positioning auxiliary devices, specifically a thread positioning auxiliary device for the mounting plate of a jacquard machine. Background Technology

[0002] In the field of jacquard weaving, the eyelet is a key component for guiding the warp threads. The precise correspondence between the hole positions and the warp threads directly affects the clarity of the fabric pattern and the weaving efficiency. The warp threads need to be inserted one by one into the specific holes of the eyelet to form an orderly warp and weft interlacing structure.

[0003] Currently, the threading of the main thread relies heavily on manual visual positioning. Workers need to hold the thread and align it with the hole position on the eyepiece. This is not only labor-intensive, but also prone to positioning errors due to visual fatigue. Especially on high-density eyepieces (small hole spacing and large number of holes), the thread is easily threaded into the wrong hole or inserted at an angle, forming "misaligned thread" or "skewed thread". This will cause the thread to entangle and break during subsequent weaving, resulting in a significant increase in the defect rate of the fabric. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4 This utility model provides a new technical solution: a jacquard machine assembly eyepiece positioning auxiliary device, including two protective boxes 4 and two rectangular sleeves 5. The two rectangular sleeves 5 are arranged in a left-right correspondence and form a rectangle when closed. The two protective boxes 4 are arranged in a front-back correspondence and the two rectangular sleeves 5 are located on opposite sides of the two protective boxes 4. A positioning auxiliary component is arranged on the two protective boxes 4 and the two rectangular sleeves 5. The positioning auxiliary component includes a bidirectional threaded rod 10, which is rotatably connected to the left and right inner walls located inside the front protective box 4.

[0031] Among them, a worm gear 13 is fixedly sleeved at the middle position of the outer wall of the bidirectional threaded rod 10, and a worm 12 is provided on the lower surface of the worm gear 13, and the worm 12 meshes with the worm gear 13.

[0032] The front end of the worm gear 12 rotates through the front surface of the protective box 4, and a rotating wheel is fixedly connected to the front end of the worm gear 12.

[0033] Furthermore, the worm gear 12 is rotatably connected to the inner wall of the protective box 4, and two movable sleeves 14 are threaded onto the outer surface of the bidirectional threaded rod 10. Two L-shaped movable plates 11 are fixedly connected to the upper and lower surfaces of the two movable sleeves 14.

[0034] Furthermore, the ends of the four L-shaped movable plates 11 that are away from the movable sleeve 14 slide through the left and right sides of the protective box 4 respectively.

[0035] Furthermore, connecting plates 3 are provided on both the left and right sides of the protective box 4, and the two connecting plates 3 are fixedly connected to the corresponding L-shaped movable plates 11 respectively.

[0036] Furthermore, a fixing plate 2 is fixedly connected to the rear surface of both connecting plates 3, and the structures on the two protective boxes 4 are set in a front-to-back mirror configuration.

[0037] Furthermore, the four fixed plates 2 are respectively fixedly connected to the corresponding concave plates 1.

[0038] Furthermore, rectangular mounting grooves 9 are provided on the inner walls of the opposite surfaces of the two concave plates 1, and rectangular mounting plates 15 are snapped into the inner walls of the two rectangular mounting grooves 9. Rectangular sleeves 5 are fixedly connected to the opposite surfaces of the two rectangular mounting plates 15.

[0039] Furthermore, two concave plates 1 are used to fix the rectangular sleeve 5. The inner wall of the rectangular sleeve 5 is fixedly connected to a fixed grid frame 7, and guide sleeves 8 are fixedly connected to multiple grids on the fixed grid frame 7.

[0040] Furthermore, the upper ends of multiple guide sleeves 8 are all fixedly connected with flared tubes 6.

[0041] Furthermore, handles are fixedly connected to the upper surfaces of both protective boxes 4, and permanent magnets are provided on the lower surfaces of both concave plates 1. The two concave plates 1 are fixed to the target plate by the attraction of the permanent magnets.

[0042] Furthermore, when using the jacquard machine's mounting plate wire positioning auxiliary device, first select the appropriate fixed grid frame 7 on the rectangular sleeve 5 according to the hole position of the eyepiece. The grid on the fixed grid frame 7 needs to correspond to the hole position of the eyepiece.

[0043] Then, the rectangular sleeve 5 is placed on the opposite side of the two concave plates 1, so that the two rectangular mounting slots 9 correspond to the two rectangular clamping plates 15, and then the two worm gears 12 are rotated by the rotating wheel;

[0044] When the rotating wheel is rotated, the worm 12 will rotate accordingly. Since the worm 12 and the worm wheel 13 mesh with each other, the worm wheel 13 will rotate synchronously. The worm wheel 13 will then drive the bidirectional threaded rod 10 to rotate inside the protective box 4 located on the front side. The threads on the outer wall of the bidirectional threaded rod 10 are opposite in direction, and the two moving sleeves 14 are threadedly connected to the bidirectional threaded rod 10. Therefore, when the bidirectional threaded rod 10 rotates, the two moving sleeves 14 will move relative to each other along its outer wall (one moves to the left and the other moves to the right).

[0045] When the movable sleeve 14 moves, it will drive the L-shaped movable plates 11 on its upper and lower surfaces to move synchronously. The four L-shaped movable plates 11 will pass out from the left and right sides of the protective box 4 respectively, pushing the connecting plates 3 on the left and right sides of the protective box 4 to move in opposite or opposite directions. The structure of the protective box 4 located on the rear side is a mirror image of the front side. Its internal bidirectional threaded rod, movable sleeve and other components will move synchronously, driving the connecting plate 3 on the rear side to move in the same direction as the front side.

[0046] The movement of the connecting plate 3 will drive the fixed plate 2 that is fixedly connected to it, thereby pushing the concave plate 1 to move. By adjusting the distance between the two concave plates 1, the rectangular mounting grooves 9 of the two rectangular sleeves 5 are precisely aligned with the rectangular clamping plate 15. Then, the worm gear 12 is rotated until the rectangular clamping plate 15 is completely inserted into the inner wall of the rectangular mounting groove 9, thereby fixing the rectangular sleeve 5 to the concave plate 1 and ensuring that the rectangular sleeve 5 will not loosen in subsequent operations.

[0047] Among them, after the two concave plates 1 are moved to the appropriate position, the permanent magnets on their lower surfaces will be attracted to the eye plate, which will firmly fix the entire device and prevent the device displacement from affecting the positioning accuracy when the wire is threaded; the two rectangular sleeves 5 close to form a complete rectangle, which is adapted to the size of the eye plate and provides a stable frame for wire positioning.

[0048] When the wire needs to be inserted into the eyepiece, one end of the wire will first pass through the guide sleeve 8 on the fixed grid frame 7 inside the rectangular sleeve 5. The upper end of the guide sleeve 8 is fixedly connected to the bell mouth tube 6. The flared structure of the bell mouth tube 6 can guide the wire to enter the guide sleeve 8 accurately and avoid the wire from deviating. The multiple grids on the fixed grid frame 7 correspond one-to-one with the holes in the eyepiece. The guide sleeve 8 further limits the wire to ensure that the wire is inserted vertically into the corresponding hole in the eyepiece, thereby improving the accuracy and efficiency of wire insertion.

[0049] If the positioning position needs to be adjusted, the rotating wheel is rotated in the opposite direction. The worm 12 drives the worm wheel 13 and the bidirectional threaded rod 10 to reverse. The moving sleeve 14 drives the L-shaped moving plate 11, the connecting plate 3 and other components to reset, so that the distance between the concave plates 1 increases. The rectangular sleeve 5 can be loosened for replacement or adjustment, and then it can be fixed again to adapt to the positioning requirements of different eye plate hole positions.
