Description

Technical Field

[0001] This utility model relates to the technical field of installation and positioning devices, specifically a quick installation and positioning device for heddles in a jacquard loom. Background Technology

[0002] In the jacquard loom assembly process, the installation and positioning of the heddles is the core link that determines the assembly efficiency and fabric quality. Its efficiency and accuracy directly affect the production progress and pattern precision.

[0003] Traditional installation methods rely on manual operation of individual heddles, which is extremely inefficient. Workers need to hold the heddles and align them one by one with the mounting holes on the heddle frame before manually inserting and fixing them. The installation of a single heddle frame (containing hundreds of heddles) is time-consuming. This method is not only labor-intensive, but also has a long manufacturing cycle due to the slow operation pace, which cannot meet the requirements of large-scale production. Especially in multi-variety, small-batch orders, the labor cost of frequent model changes is even higher. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a quick installation and positioning device for heddles in jacquard loom assembly machines. This solves the problem of traditional installation methods that rely on manual single-hedle operation, resulting in extremely low efficiency. Workers need to hold the heddles and align them one by one with the mounting holes on the heddle frame before manually inserting and fixing them. The installation of a single heddle frame (containing hundreds of heddles) is time-consuming. This method is not only labor-intensive but also results in a long assembly cycle due to the slow operation pace, making it unsuitable for the pace requirements of large-scale production. In particular, the high time cost due to frequent model changes in multi-variety, small-batch orders is a significant issue.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick installation and positioning device for heddles of a jacquard machine assembly machine, comprising a fixing plate, wherein two rectangular mounting slots are provided on the upper surface of the fixing plate, and both rectangular mounting slots extend through the lower surface of the fixing plate;

[0008] The mounting and positioning components are installed in two rectangular mounting slots and include two protective boxes.

[0009] The two protective boxes are fixedly installed in the inner walls of the two rectangular mounting slots, and each of the two protective boxes has a sliding groove on its left side that communicates with its interior.

[0010] The upper surfaces of both protective boxes are fixedly equipped with servo motors, and the output ends of both servo motors are fixedly connected with threaded rods.

[0011] The lower ends of the two threaded rods rotate and penetrate into the interior of the corresponding protective box, and are rotatably connected to the inner wall of the corresponding protective box.

[0012] Preferably, the outer walls of both threaded rods are threaded with movable sleeves, and the left sides of both movable sleeves are fixedly connected with movable blocks. The left sides of the two movable blocks slide through the inner walls of the corresponding grooves.

[0013] Preferably, a second cylinder is fixedly installed on the left side of each of the two movable blocks, and a support plate is fixedly installed on the opposite side of the two second cylinders.

[0014] Preferably, the telescopic ends of the two second cylinders are fixedly connected to a second fixing plate, and two first cylinders are fixedly installed on the right side of the two second fixing plates.

[0015] Preferably, the telescopic ends of both first cylinders slide through the left side of the second fixed plate, and the telescopic ends of the two first cylinders are fixedly connected to the first fixed plate.

[0016] Preferably, the opposing surfaces of the first fixing plate and the second fixing plate are provided with semi-circular fixing grooves.

[0017] Preferably, two connecting plates are fixedly connected to both the left and right sides of the fixed plate, and movable wheels are fixedly installed on the lower surface of the four connecting plates.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a quick installation and positioning device for heddles in a jacquard machine assembly, which has the following advantages:

[0020] This jacquard machine assembly machine heddle wire quick installation and positioning device uses a first cylinder and a second fixed plate to clamp the heddle wire, a servo motor to drive and adjust the height, and a second cylinder to finely adjust the left and right positions. All components work together to achieve rapid positioning and installation of the heddle wire, greatly improving the efficiency and accuracy of heddle wire installation during the jacquard machine assembly process.

[0021] When the telescopic ends of the two first cylinders of the jacquard loom's quick heddle wire installation and positioning device move the first fixed plate to the right, the opposing surfaces of the first and second fixed plates gradually approach each other. The semi-circular fixing grooves on both plates will then join together to form a complete circular fixing hole, firmly clamping the multiple heddle wires placed in the semi-circular fixing groove. Through the constraint of the circular fixing hole, the heddle wires are prevented from shifting due to shaking during installation, ensuring the accurate position of each heddle wire and providing a foundation for subsequent docking with the heddle frame.

[0027] 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.

[0028] Please see Figure 1-4 This utility model provides a new technical solution: a quick installation and positioning device for heddles of a jacquard machine assembly machine, including a fixing plate 1, two rectangular mounting slots 12 are opened on the upper surface of the fixing plate 1, both rectangular mounting slots 12 penetrate through the lower surface of the fixing plate 1, and a positioning component is installed on the two rectangular mounting slots 12. The positioning component includes two protective boxes 7.

[0029] Among them, the two protective boxes 7 are fixedly installed in the inner walls of the two rectangular mounting slots 12 respectively, and the left side of each of the two protective boxes 7 is provided with a sliding groove 6 that communicates with its interior.

[0030] Among them, servo motors 11 are fixedly installed on the upper surface of the two protective boxes 7, and threaded rods 15 are fixedly connected to the output ends of the two servo motors 11.

[0031] The lower ends of the two threaded rods 15 are rotatably inserted into the interior of the corresponding protective box 7 and are rotatably connected to the inner wall of the corresponding protective box 7.

[0032] Furthermore, the outer walls of the two threaded rods 15 are threaded with movable sleeves 14, and the left sides of the two movable sleeves 14 are fixedly connected with movable blocks 13. The left sides of the two movable blocks 13 slide through the inner walls of the corresponding grooves 6 respectively.

[0033] Furthermore, a second cylinder 10 is fixedly installed on the left side of each of the two movable blocks 13, and a support plate 5 is fixedly installed on the opposite side of the two second cylinders 10.

[0034] Furthermore, the telescopic ends of the two second cylinders 10 are fixedly connected to the second fixing plates 8, and two first cylinders 9 are fixedly installed on the right side of the two second fixing plates 8.

[0035] Furthermore, the telescopic ends of both first cylinders 9 slide through the left side of the second fixed plate 8, and the telescopic ends of the two first cylinders 9 are fixedly connected to the first fixed plate 4.

[0036] Furthermore, semi-circular fixing grooves are provided on the opposite surfaces of the first fixing plate 4 and the second fixing plate 8.

[0037] Furthermore, two connecting plates 2 are fixedly connected to both the left and right sides of the fixed plate 1, and four moving wheels 3 are fixedly installed on the lower surface of the four connecting plates 2.

[0038] Furthermore, when using the jacquard machine assembly heald wire quick installation and positioning device, firstly, the fixed plate 1 is moved to the relative position with the heald frame by the four moving wheels 3, and then the heald frame is lifted (or the lifting heald belt is tensioned by manual drive) so that the upper beam hook and the lower beam slot are horizontally aligned (forming a vertical installation reference line).

[0039] Then, multiple heddles are placed inside multiple semi-circular fixing slots, and then two first cylinders 9 are activated. The telescopic ends of the two first cylinders 9 drive the first fixing plate 4 to move to the right.

[0040] When the telescopic ends of the two first cylinders 9 drive the first fixed plate 4 to move to the right, the opposite surfaces of the first fixed plate 4 and the second fixed plate 8 gradually approach each other, and the semi-circular fixing grooves on the two will be spliced ​​into a complete circular fixing hole, which firmly clamps the multiple heddles placed in the semi-circular fixing groove. Through the constraint of the circular fixing hole, the heddles are prevented from shifting due to shaking during installation, ensuring the accurate position of each heddle and providing a basis for subsequent docking with the heddle frame.

[0041] After the heald wire is fixed, two servo motors 11 are started. The output end of the servo motors 11 drives the threaded rod 15 to rotate inside the protective box 7. Since the threaded rod 15 is threadedly connected to the movable sleeve 14, and the movable sleeve 14 is slidably connected to the slide groove 6 on the left side of the protective box 7 through the movable block 13 (the slide groove 6 restricts the rotation of the movable sleeve 14, so that it can only move along the axial direction), the rotation of the threaded rod 15 will cause the movable sleeve 14 to move up and down along its outer wall. Then, through the movable block 13, the second cylinder 10, the support plate 5 and the fixed heald wire will move up and down synchronously, adjusting the height position of the heald wire so that it is precisely aligned with the installation reference line on the heald frame (the horizontal alignment line between the upper beam hook and the lower beam slot).

[0042] If the left and right positions of the heddle wire need to be finely adjusted, the two second cylinders 10 are activated. The extension and retraction ends of the second cylinders 10 drive the second fixing plate 8, the first cylinder 9, the first fixing plate 4 and the heddle wire as a whole to move left and right. Through fine adjustment, the installation position of the heddle wire is ensured to be completely aligned with the mounting holes on the heddle frame, so as to avoid installation difficulties or wear of the heddle wire during subsequent use due to position deviation.

[0043] Among them, the two protective boxes 7 are fixed in the rectangular mounting slot 12 to protect the internal threaded rod 15, movable sleeve 14 and other components, and reduce the impact of external dust or debris on the transmission.

[0044] When the height and left and right positions of the heddle wire are adjusted to align with the mounting point of the heddle frame, all driving components are stopped, and the heddle wire can be quickly installed onto the heddle frame. After installation, the first cylinder 9 is started in reverse, and the first fixing plate 4 moves to the left to disengage from the heddle wire and release the clamp. Then, the servo motor 11 and the second cylinder 10 drive each component to reset, preparing for the installation of the next batch of heddle wires.

[0045] Among them, the lower surface of the connecting plates 2 on the left and right sides of the fixed plate 1 is provided with moving wheels 3, which facilitates the overall movement of the device and allows for flexible adjustment of the device placement according to the position of different heddle frames, improving the convenience of operation; the rectangular mounting groove 12 provides installation space for the protective box 7, ensuring that the device structure is compact and does not occupy additional operating space;

[0046] The first cylinder 9 and the second fixing plate 8 work together to clamp the heddle wire, the servo motor 11 drives the height adjustment, and the second cylinder 10 finely adjusts the left and right positions. All components work together to achieve rapid positioning and installation of the heddle wire, which greatly improves the efficiency and accuracy of heddle wire installation during the jacquard machine assembly process.
