Description

Technical Field

[0001] The utility model relates to the field of jacquard machines, and more specifically, to a needle arm fixing structure of the jacquard machine. Background Art

[0002] Jacquard machine is a textile tool. On the jacquard machine, the pattern plate is put on the pattern tube. Every time a weft is woven, a pattern plate is turned over, and the pattern tube is pressed against the transverse needle once. When there are holes on the pattern plate, the head end of the transverse needle is inserted into the holes of the pattern plate and the pattern tube, so that the hook end of the straight needle is still hung on the lifting knife. When the lifting knife rises, the straight needle rises with it, and the heddle is lifted up by the first line hook and the wire harness. At this time, the warp thread inserted into the heddle eye is also lifted up to form the upper layer of the shuttle. The electronic jacquard machine can transform traditional manual operation into automatic machine operation, greatly reducing the labor intensity of the staff.

[0003] The needle lifting arm in the jacquard machine is traditionally composed of two splints, and the lower end is connected to a connecting rod for connecting the lifting knife. The number of connecting rods at the lower end of the needle lifting arm is generally multiple. Bolts and nuts are usually used to fix the connecting rods, which is more troublesome to install. In addition, special tools for bolts are also required for the subsequent disassembly of the connecting rods. At the same time, when the existing bolts are rusted, the disassembly difficulty will be increased.

[0004] Therefore, the Chinese patent with publication number CN220149750U discloses a fixing structure for the needle arm of an electronic jacquard machine to solve the above problem. Although this solution does not require the use of bolts to fix the connecting rod, each time the connecting rod is installed and removed, the rotating wheel needs to be rotated multiple times, and the rotating wheel is located between the two clamping plates. The user needs to put his hand into it every time, which is inconvenient to operate due to the small space.

[0005] Therefore, a solution needs to be proposed to solve this problem. Utility Model Content

[0023] The utility model is described in detail below in conjunction with the accompanying drawings.

[0024] A needle arm fixing structure of a jacquard machine, such as Figures 1 to 3As shown, it includes a horizontal plate 1, both sides of which are fixedly connected with a clamping plate 2, the horizontal plate 1 is provided with a plurality of connecting rods 3, the horizontal plate 1 is provided with a plurality of slots 4 for the connecting rods 3 to be inserted, an insert block 5 is slidably connected in the slot 4, the connecting rod 3 is provided with a positioning slot 6 for the insert block 5 to be inserted, the insert block 5 is fixedly connected with an insert rod 7, a spring 8 is sleeved on the insert rod 7, a shifting rod 9 is fixedly connected to the insert rod 7, and a through slot 10 for the shifting rod 9 to pass through and move is provided on the horizontal plate 1 and the clamping plate 2.

[0025] Furthermore, a linkage rod 11 is fixedly connected to the insertion rod 7, a pull rod 13 is slidably connected to the cross plate 1, and a plurality of linkage grooves 15 for the linkage rod 11 to be inserted and moved are provided on the pull rod 13.

[0026] Furthermore, the cross section of the pull rod 13 is a polygonal structure.

[0027] Furthermore, bolts 16 are threadedly connected to the transverse plate 1 , and a plurality of limiting grooves 17 for the bolts 16 to be inserted into are formed on the linkage rod 11 .

[0028] Furthermore, the bolt 16 is a hand-tightened bolt 16 .

[0029] Furthermore, a slope 18 is formed on the insert block 5 .

[0030] Working principle: when the connecting rod 3 needs to be installed, the user inserts the connecting rod 3 into the slot 4. During the insertion of the connecting rod 3, the insert block 5 will automatically make way for the connecting rod 3 through the slope 18 until the top of the connecting rod 3 abuts against the top wall of the slot 4. At this time, the insert block 5 will be inserted into the positioning groove 6 under the push of the spring 8, thereby completing the installation of the connecting rod 3. When a single connecting rod 3 needs to be removed, the lever 9 is pulled to move the lever 9 along the trajectory of the through slot 10, thereby driving the insert block 5 to move into the storage slot 19. At this time, the connecting rod 3 loses the restriction of the insert block 5, and the connecting rod 3 can be removed. When it is necessary to remove the connecting rods 3 in batches, pull the pull rod 13 outward, and the pull rod 13 will drive the movement of the several linkage rods 11 through the several linkage grooves 15, so that all the plug blocks 5 are moved into the storage grooves 19, so that all the connecting rods 3 can be removed. After the installation of all the connecting rods 3 is completed, push the pull rod 13 inward until the pull rod 13 can no longer move, and then limit the pull rod 13 through the bolt 16 and the limit groove 17. At this time, the linkage groove 15 will limit the linkage rod 11, so that the plug block 5 can no longer be displaced, thereby further strengthening the limiting effect on the connecting rod 3.

[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
