Description

Technical Field

[0001] This invention relates to a head structure for a jacquard ribbon weaving machine, specifically a head structure installed on a jacquard ribbon weaving machine for driving the jacquard knife to rise and fall. Prior Technology

[0002] A jacquard ribbon loom is a device that interweaves warp and weft yarns into a ribbon-like fabric. The "jacquard" aspect involves controlling the rise and fall of the warp yarns, allowing the ribbon to display various patterns, text, or designs. The power source for the jacquard knives comes from a head structure mounted above the machine. This structure must continuously and accurately transmit power to the jacquard knives at high speed, which is crucial for maintaining consistent overall weaving quality.

[0003] Most existing head structures use an eccentric drive combined with a rocker arm and connecting rod to form a transmission structure, which uses periodic oscillation to drive the jacquard knife holder to rise and fall. Although this transmission method can complete the reciprocating motion of the jacquard knife, the force generated by the eccentric drive during operation is not completely symmetrical. In addition, the components are generally located on the outside of the head structure, making the overall structure prone to torque from different directions during operation. This causes the machine to shake in both the horizontal and vertical directions. This deviation not only affects the stability of the machine, but also reduces the accuracy of the jacquard knife operation.

[0004] When the shaking persists, the relative positions of the warp and weft yarns may shift, causing problems such as snagging, tangling, or breakage during operation. Especially during long-term continuous production, this instability is more likely to cause misalignment of the webbing pattern, deformation of the design, or even scrap of the finished product. This not only reduces production efficiency but also increases raw material consumption and maintenance costs, placing a considerable burden on businesses.

[0005] In view of this, the inventor has devoted a lot of time to studying relevant knowledge, conducting research and development of related products, and after many experiments and tests, finally launched a jacquard weaving machine head structure, which can effectively reduce the shaking caused by eccentric drive, thereby improving the above-mentioned shortcomings and meeting the needs of the public. Summary of the Invention

[0006] The main objective of this invention is to improve the structural stability of jacquard looms during long-term operation and ensure the quality of ribbon products. It avoids the uneven force caused by eccentric transmission in existing jacquard looms, which leads to machine vibration, resulting in misalignment of the ribbon pattern or decreased precision, affecting product consistency. To achieve the above objective and overcome the shortcomings of conventional methods, this invention provides a headstock structure for a jacquard ribbon loom, comprising two parallel wall plates, each with a headstock drive structure on its outer wall. Each faucet drive structure includes: an upper arm and a lower arm, one end of each upper arm and lower arm being coaxially connected to a connecting rod, which is mounted between the two wall panels to allow each upper arm and corresponding lower arm to swing synchronously; an eccentric drive assembly, each eccentric drive assembly being fixed to a corresponding wall panel and connected to the corresponding upper arm and lower arm, and driving the corresponding upper arm and lower arm to swing and rotate around the connecting rod as an axis; and a linkage shaft, which is laterally arranged between the two wall panels. A pivot shaft, with each pivot shaft passing through the two wall panels; an interlocking movable assembly, each interlocking movable assembly having a first swing rod, a second swing rod, a first connecting member, a third swing rod, a fourth swing rod, and a second connecting member, one end of each first swing rod being connected to a corresponding upper arm rod, the other end of each first swing rod being connected to one end of a corresponding first connecting member, the other end of each first connecting member being connected to one end of a corresponding second swing rod, one end of each third swing rod being connected to a corresponding lower arm rod, the other end of each third swing rod being connected to one end of a corresponding second connecting member, the other end of each second connecting member being connected to one end of a corresponding fourth swing rod, and the centers of each first swing rod and the corresponding third swing rod being coaxially connected to the linkage shaft, and the centers of each second swing rod and the corresponding fourth swing rod being coaxially connected to the corresponding pivot shaft; a plurality of jacquard assemblies, each jacquard assembly being assembled with the other end of a corresponding second swing rod or the other end of a corresponding fourth swing rod.

[0007] According to the technology defined above, the advantage of this invention lies in the fact that by combining the interlaced moving components with the dual-axis structure of the connecting shaft and the fulcrum shaft, a coordinated support and linkage effect can be formed during operation, so that the overall structure can still maintain balance when driven eccentrically, reducing swaying and making the jacquard movement more stable and smooth, thereby improving the precision of the ribbon pattern and the consistency of the product. It is evident that this invention is indeed practical and progressive, and is worthy of promotion in the industry. Simple Explanation of the Diagram

Implementation

[0009] To clearly illustrate the aforementioned objectives and effects achieved by the present invention, its features and effects are described in detail with reference to the accompanying drawings. Referring to Figures 1 to 15, the present invention provides a head-driven structure for a jacquard weaving machine, which has two parallel wall plates 1. The outer walls of each of the two wall plates 1 each have a head-driven structure 2. Each head-driven structure 2 includes an upper arm rod 21 and a lower arm rod 22. One end of each upper arm rod 21 and each lower arm rod 22 is coaxially connected to a connecting rod 5, which is mounted on the two wall plates 1. Between the plates 1, the upper arm 21 and the corresponding lower arm 22 can swing synchronously; an eccentric drive assembly 23, each eccentric drive assembly 23 is fixed to the corresponding wall plate 1 and connected to the corresponding upper arm 21 and lower arm 22, and drives the corresponding upper arm 21 and lower arm 22 to swing and rotate around the connecting rod 5 as the axis; a connecting shaft 6, which is laterally arranged between the two wall plates 1; a fulcrum shaft 8, each fulcrum shaft 8 is respectively connected to the two wall plates 1; an interlaced movable assembly 3, each interlaced movable assembly 3 respectively It includes a first swing rod 31, a second swing rod 32, a first connecting member 35, a third swing rod 33, a fourth swing rod 34, and a second connecting member 36. One end of each first swing rod 31 is connected to a corresponding upper arm rod 21, and the other end of each first swing rod 31 is connected to one end of a corresponding first connecting member 35. The other end of each first connecting member 35 is connected to one end of a corresponding second swing rod 32. One end of each third swing rod 33 is connected to a corresponding lower arm rod 22. The other end of each component is connected to one end of a corresponding second connecting member 36, and the other end of each second connecting member 36 is connected to one end of a corresponding fourth swing rod 34. The centers of each first swing rod 31 and the corresponding third swing rod 33 are coaxially connected to the linkage shaft 6, and the centers of each second swing rod 32 and the corresponding fourth swing rod 34 are coaxially connected to the corresponding fulcrum shaft 8. A plurality of jacquard assemblies 4 are assembled with the other end of a corresponding second swing rod 32 or the other end of a corresponding fourth swing rod 34. The drawings used herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0010] When the user starts the machine, the eccentric drive components 23 on both sides begin to rotate, causing the upper arm 21 and lower arm 22 connected to them to swing alternately around the connecting rod horizontally positioned between the two wall plates 1. Since one end of each upper arm 21 and the corresponding lower arm 22 is coaxially connected to the connecting rod 5, when the eccentric drive components 23 rotate, the upper arm 21 and lower arm 22 can swing in opposite directions. As each upper arm 21 and lower arm 22 swings, the connected staggered moving components 3 will also move synchronously. At this time, the dual-axis support formed by the connecting shaft 6 and the fulcrum shaft 8 makes the staggered movement between the swinging rods more stable and precise. It can effectively disperse the unbalanced torque generated by the eccentric drive, reducing the swaying of the overall structure. Furthermore, when the first swing rod 31 and the second swing rod 32 or the third swing rod 33 and the fourth swing rod 34 swing alternately, their other ends will drive the connected jacquard components 4 to reciprocate up and down, thereby completing the jacquard action. During this process, the eccentric drive component 23 ensures the symmetry of the drive, the connecting rod 5 provides the common rotation axis of the upper arm rod 21 and the lower arm rod 22, and the staggered moving component 3 improves the balance and accuracy of the operation through the connecting shaft 6 and the fulcrum shaft 8, so that the action of the jacquard components 4 is consistent, ultimately achieving stable operation and improving the quality of the webbing.

[0011] Furthermore, in order to ensure that each swing arm can be stably assembled with its corresponding connecting member, each first connecting member 35 further has a first connecting area 351 and a second connecting area 352. One end of each first swing arm 31 is connected to the corresponding upper arm 21, and the other end of each first swing arm 31 is respectively assembled in the corresponding first connecting area 351. One end of each second swing arm 32 is respectively assembled in the corresponding second connecting area 352, and the other end of each second swing arm 32 is respectively assembled with any jacquard component 4. Also, each second connecting member 36 further has a third connecting area 361 and a fourth connecting area 362. One end of each third swing arm 33 is connected to the corresponding lower arm 22, and the other end of each third swing arm 33 is respectively assembled in the corresponding third connecting area 361. One end of each fourth swing arm 34 is respectively assembled in the corresponding fourth connecting area 362, and the other end of each fourth swing arm 34 is respectively assembled with any jacquard component 4. By establishing clear assembly positions between each swing rod and each connecting component, and through the division of different joint areas, not only can installation errors be reduced, but the correct force direction of each component during operation can also be ensured, avoiding wear or displacement due to uneven force, so that the jacquard assembly 4 can operate more smoothly and accurately.

[0012] Continuing from the previous explanation, to further ensure the stability of the connection between each swing rod and its corresponding connecting component, and to prevent disintegration due to unstable assembly during machine operation, a plurality of fixing components 9 are provided. Each fixing component 9 passes through each first swing rod 31 and its corresponding first connecting component 35, each second swing rod 32 and its corresponding first connecting component 35, each third swing rod 33 and its corresponding second connecting component 36, and each fourth swing rod 34 and its corresponding second connecting component 36, so that each first connecting component 35 is connected to its corresponding first swing rod 31 and second swing rod 32, and each second connecting component 36 is connected to its corresponding third swing rod 33 and fourth swing rod 34. The fixing components 9 prevent the connecting components from loosening due to vibration or friction during high-speed or long-term operation, thus affecting machine operation. They also further ensure the connection between each swing rod and its connecting component, improving the overall structural stability under long-term operation.

[0013] Furthermore, to ensure the correct installation of the pivot shaft 8 and maintain its rotational support function, each pivot shaft 8 is further provided with a pivot seat 81 and a shaft member 82. Each pivot seat 81 is respectively assembled on the inner wall surface of the two wall plates 1. Each shaft member 82 has one end inserted through the corresponding pivot seat 81, and the other end of each shaft member 82 passes through the corresponding wall plate 1. By stably assembling each pivot shaft 8 on the corresponding wall plate 1, it is possible to prevent the pivot shaft 8 from shifting due to force during operation, and to ensure that it can withstand the pressure of repeated action of each swing arm. Moreover, the stable support of the pivot seat 81 can prevent the shaft member 82 from shaking due to any reason, which would affect the jacquard operation or cause excessive shaking of the machine.

[0014] Furthermore, in order to ensure that the connecting shaft 6 and the fulcrum shaft 8 can stably cooperate with each swing rod to complete the jacquard operation, each first swing rod 31 has a first assembly hole 311 at its center, and each third swing rod 33 has a third assembly hole 331 at its center. The two ends of the connecting shaft 6 are respectively connected to the corresponding first assembly hole 311 and the corresponding third assembly hole 331. Also, each second swing rod 32 has a second assembly hole 321 at its center, and each fourth swing rod 34 has a fourth assembly hole 341 at its center. Each fulcrum shaft 8 is respectively connected to the corresponding second assembly hole 321 and the corresponding fourth assembly hole 341. The arrangement of the assembly holes allows the connecting shaft 6 and the fulcrum shaft 8 to be quickly aligned during installation and maintains a tight connection between the connecting shaft 6 and the fulcrum shaft 8 and each swing rod during operation. This not only reduces frictional wear between parts but also ensures that each swing rod maintains a consistent angle change during swinging, preventing uneven jacquard movements caused by shaft misalignment and further ensuring the quality of the webbing pattern.

[0015] Furthermore, in order to stably transmit power and ensure that each arm component can swing smoothly in sync, each eccentric drive assembly 23 further includes a first connecting arm 231, a first synchronous wheel 232, an eccentric shaft 233, a second connecting arm 234, a second synchronous wheel 235, and a universal bearing 236. Each universal bearing 236 is respectively assembled inside the corresponding wall panel 1. Each eccentric shaft 233 is respectively connected to the corresponding universal bearing 236. Each first synchronous wheel 232 and each second synchronous wheel 235 are respectively eccentrically connected to the corresponding eccentric shaft 233. One end of each first connecting arm 231 is respectively connected to the corresponding first synchronous wheel 232, and the other end of each first connecting arm 231 is respectively connected to the corresponding upper arm 21. One end of each second connecting arm 234 is respectively connected to the corresponding second synchronous wheel 235, and the other end of each second connecting arm 234 is respectively connected to the corresponding lower arm 22. When the eccentric shaft 233 rotates, it synchronously drives the first synchronous wheel 232 and the second synchronous wheel 235 to operate, thereby pushing the connected first connecting arm 231 and the second connecting arm 234 to reciprocate. This drives the upper arm 21 and the lower arm 22 to produce alternating movements, ensuring the continuity and stability of the overall drive process. In addition, the eccentric shaft 233 can adopt a coaxial structure, that is, it is set between the two wall plates 1, and its two ends extend outward through the wall plates 1 respectively, so that the left and right sides remain coaxial. During the transmission process, the universal bearing 236 can appropriately release stress concentration according to the angle difference generated by the swing of the first connecting arm 231 and the second connecting arm 234, thereby reducing the torque load on the machine tool, so that the overall system can maintain smooth operation and have better durability even after long-term operation.

[0016] To stabilize the swinging motion and ensure the guiding accuracy and alignment consistency of the jacquard components 4 during lifting and lowering, each jacquard component 4 further includes a connecting component 41, two horizontal plates 42, a plurality of vertical plates 43, and a plurality of lifting blocks 44. One end of each connecting component 41 is connected to a corresponding staggered movable component 3, and the other end of each connecting component 41 is connected to a corresponding two horizontal plates 42. Each vertical plate 43 is fixed at one end between a corresponding two horizontal plates 42, and each lifting block 44 is disposed at the other end of each vertical plate 43. With this structural configuration, the jacquard component 4 can maintain a stable position during operation and effectively guide its vertical movement, or maintain a smooth path when approaching or moving away from the staggered movable component 3, thereby ensuring more precise jacquard movements and improving the weaving effect and overall quality.

[0017] Continuing from the previous explanation, to prevent the jacquard component 4 from shifting left or right or getting stuck during repeated lifting and lowering, a bakelite partition 7 is further provided on the outer side of each of the two wall panels 1. Each lifting blade 44 is positioned between the bakelite partitions 7, and a plurality of vertical rods 71 ​​are provided on the outer side of each bakelite partition 7. The bakelite partitions 7 and the vertical rods 71 ​​together restrict the left and right swaying of each lifting blade 44 and maintain its lifting and lowering guidance. Compared with the traditional method of directly slotting the wall panel 1 to form a guide structure, the design of bakelite partitions 7 combined with vertical rods 71 ​​not only has higher wear resistance and durability, but also reduces the guiding deviation caused by machining accuracy errors. At the same time, the components are easier to disassemble and replace, reducing the cost of subsequent maintenance, thereby extending the service life of the overall equipment and ensuring the stability of the operation process.
