AI Technical Summary
The hook fixing structure of the traditional jacquard machine cylinder is prone to loosening, leading to frequent disassembly and damage, which affects knitting efficiency and pattern complexity. Furthermore, the hook cannot be reset when the yarn is taut or not cut in time.
By using a limiting plate instead of a spring, the combination of the limiting plate and the spring achieves stable fixation and assisted reset of the hook, simplifying the hook replacement process.
It improves the stability and ease of replacement of crochet hooks, ensures knitting efficiency and pattern quality, reduces crochet hook damage, and extends the service life and production efficiency of jacquard machines.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of jacquard machine technology, specifically to a jacquard machine syringe. Background Technology
[0002] As a key piece of equipment in textile machinery for weaving complex patterns, the technological evolution of the jacquard machine directly affects fabric quality and production efficiency. The modern textile industry is developing towards higher speeds and greater intelligence, placing higher demands on the precision, durability, and ease of maintenance of the cylinder components. As the "execution center" of the jacquard machine, the cylinder, through the cooperation of the hook needle and the top needle, completes the yarn hooking and weaving actions; its performance directly determines the complexity of the fabric pattern and the continuity of the weaving process.
[0003] Traditional syringes often use a "bolt + pressure plate" structure to fix the hook. Replacing a single hook requires disassembling the upper hook plate, lower hook plate, and limiting components. The limiting components are usually springs that fit around the hook. According to statistics, jacquard machines need to replace hooks about 300 times a year due to wear. Frequent disassembly can cause the springs to loosen, thus failing to effectively fix the hook. Long-term use can lead to easy damage to the hook.
[0004] At the same time, if the yarn is too tight or not cut in time during the process of hooking the yarn, the hook will not be able to return to the lower hook plate, which will affect the knitting efficiency. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] In view of the shortcomings of the existing technology, this utility model provides a jacquard machine needle cylinder. By adjusting the limiting component, the limiting component is changed from the original spring to a limiting plate, which solves the problem of not being able to effectively limit the hook needle.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A jacquard machine syringe includes a mounting plate. A rotating cylinder is movably connected to the upper part of the mounting plate. An upper hook needle plate is fixedly connected to one side of the rotating cylinder, and a lower hook needle plate is fixedly connected to one side of the rotating cylinder. The upper hook needle plate is located above the lower hook needle plate. A plurality of hook needles are installed inside the upper and lower hook needle plates. A plurality of fixing rods are fixedly connected to the upper part of the lower hook needle plate. Limiters are movably connected to the fixing rods. The limiters consist of a first limiter and a second limiter and are located outside the hook needles. A ejector pin is fixedly connected to the upper part of the mounting plate. The ejector pin is located between the lower hook needle plate and the rotating cylinder, and the hook needles move on the ejector pin.
[0010] Preferably, a first positioning post is fixedly connected to the upper part of the hook, a spring is installed on the outside of the first positioning post, a second positioning post is fixedly connected to the lower part of the limiter, and the other end of the spring is installed on the second positioning post.
[0011] Preferably, the first limiter includes an annular plate, a connecting groove, and a fixing groove, wherein the connecting groove and the fixing groove are respectively fixed to both ends of the annular plate.
[0012] Preferably, the second limiter comprises an annular plate, a fixing block, and a connecting block, wherein the fixing block and the connecting block are respectively fixed at both ends of the annular plate.

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, the present invention provides a jacquard machine syringe, which has the following beneficial effects:
[0019] During operation, the fixing pin is removed from the through hole on the connecting block and the connecting groove. By rotating the annular plate, the first limiter and the second limiter are separated. Then, the hook is removed from the hook groove of the upper hook plate and the lower hook plate and replaced. The new hook is placed into the hook groove. By rotating the first limiter and the second limiter, the connecting block at one end of the second limiter is placed into the connecting groove at one end of the first limiter. The fixing pin connects the rotating first limiter and the second limiter together, thereby effectively fixing the hook to the device through the limiter.
[0020] During operation, the hook is lifted by the pin and hooks the yarn. If the yarn is too tight or not cut in time, the hook cannot return to its original position. The spring helps to return the hook to its original position. Attached Figure Description

[0048] Furthermore, when the hook 32 is lifted by the ejector pin 5, the lower part of the hook 32 is inside the hook groove 34.
[0049] Working principle: When replacing the hook 32, remove the spring 6 corresponding to the area of the hook 32 to be replaced from the limiter 4 to facilitate rotation of the first limiter 41 and the second limiter 42. Remove the fixing pin from the through hole on the connecting block 422 and the connecting groove 412. By rotating the annular plate 411, separate the first limiter 41 and the second limiter 42. Then, remove the hook 32 from the hook groove 34 of the upper hook plate 3 and the lower hook plate 31 to replace the hook 32. Place the new hook 32 into the hook groove 34. By rotating the first limiter 41 and the second limiter 42, the second limiter 42... One end of the connecting block 422 is placed inside the connecting groove 412 at one end of the first limiter 41. The first limiter 41 and the second limiter 42 are connected together by a fixing pin. Then, the two ends of the spring 6 are respectively sleeved on the first positioning post 321 on the upper part of the lower hook plate 31 and the second positioning post 43 on the lower part of the limiter 4 to complete the replacement of the hook 32. In use, the upper hook plate 3 and the lower hook plate 31 are rotated by rotating the cylinder 2. During the rotation, the hook 32 is lifted by the pusher 5. When the hook 32 cannot be reset, the spring 6 resets the hook 32 by the elastic force of the spring 6.
[0050] In summary, during operation, the fixing pin is removed from the through hole on the connecting block 422 and the connecting groove 412. By rotating the annular plate 411, the first limiter 41 and the second limiter 42 are separated. Then, the hook 32 is removed from the hook groove 34 of the upper hook plate 3 and the lower hook plate 31. The hook 32 is replaced by placing the new hook 32 into the hook groove 34. By rotating the first limiter 41 and the second limiter 42, the connecting block 422 at one end of the second limiter 42 is placed into the connecting groove 412 at one end of the first limiter 41. The fixing pin connects the rotating first limiter 41 and the second limiter 42 together, thereby fixing the hook 32 to the device through the limiter 4.
[0051] During operation, the hook 32 is lifted by the pin 5 and the hook 32 is used to weave the fabric. When the hook 32 cannot be reset, the spring 6 will reset the hook 32 under the action of the spring force.
