DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Reference Figures 1 to 12As shown: a webbing jacquard machine, comprising a mounting frame 1 mounted on a jacquard machine body, a jacquard structure 2 and a synchronous drive structure 3; the jacquard structure 2 has an even number, the even number of jacquard structures 2 are divided into two groups, and are respectively arranged at both ends of the mounting frame 1, the jacquard structure 2 comprises a first rotating shaft 21, a lifting structure 22 and a knitting head 23, both ends of the first rotating shaft 21 are connected to the mounting frame 1, and both ends of the first rotating shaft 21 are connected to the synchronous drive structure 3, the lifting structure 22 is suspended on the first rotating shaft 21, the lifting structure 22 is used to adjust the descending stroke of the knitting head 23, the knitting head 23 is arranged at the lower end of the lifting structure 22, when the first rotating shaft 21 swings within the driving range of the synchronous drive structure 3, the first rotating shaft 21 drives the knitting head 23 along its axis through the lifting structure 22 Reciprocating motion; the synchronous drive structure 3 is arranged in the middle of the installation frame 1, and the synchronous drive structure 3 includes a second rotating shaft 31, the second rotating shaft 31 is parallel to the first rotating shaft 21, and driving wheel assemblies 32 are arranged at both ends of the second rotating shaft 31, and the driving wheel assembly 32 includes a first driving wheel 321, and the first driving wheel 321 has two symmetrically arranged protrusions. When the second rotating shaft 31 rotates around its own axis, it can drive the two first driving wheels 321 to rotate, and the outside of the two first driving wheels 321 are both covered with a rectangular frame 33, and the rectangular frame 33 is connected to the installation frame 1, and two rigid transmission structures 34 are symmetrically arranged at both ends of the rectangular frame 33. The two rigid transmission structures 34 respectively connect the two ends of the first driving wheel 321 with the first rotating shaft 21 in the jacquard structure 2 at both ends of the installation frame 1.

[0038] First, input the preset pattern program and mechanical program into the jacquard machine, the jacquard structure 2 is first adjusted according to the needs of the pattern, and the downward stroke of the knitting head 23 is adjusted through the self-adjustment of the lifting structure 22, so that the downward stroke of the knitting head 23 meets the needs of the pattern. When the second rotating shaft 31 rotates around its own axis, the second rotating shaft 31 drives the two first driving wheels 321 to rotate. When the two protrusions of the first driving wheel 321 rotate to a horizontal state, the first driving wheel 321 applies a force away from the second rotating shaft 31 to the two rigid transmission structures 34. The two rigid transmission structures 34 simultaneously transmit the two forces to the first rotating shafts 21 at both ends of the mounting frame 1 respectively. The first rotating shaft 21 rotates around its axis in a direction away from the second rotating shaft 31, and the first rotating shaft 21 drives the knitting head 23 to rise upward through the lifting structure 22. When the two protrusions of the first driving wheel 321 rotate to a vertical state, the first driving wheel 321 applies a force toward the second rotating shaft 31 to the two rigid transmission structures 34. The force drives the first rotating shaft 21 to rotate toward the second rotating shaft 31 through the rigid transmission structure 34. The first rotating shaft 21 drives the knitting head 23 to descend through the first lifting structure 22. By using a single power source to drive the two jacquard structures 2 at the same time, the energy loss of the mechanical structure is simplified and the energy efficiency of the whole machine is improved. The design of the rigid connection structure 351 reduces the energy loss in the power transmission process, so that the driving force can act on the jacquard structure 2 more effectively, thereby ensuring the high consistency and accuracy of the multiple knitting heads 23 linked with the second rotating shaft 31 in synchronous movement, and improving the pattern accuracy and consistency during the weaving process.

[0039] Reference Figure 3 , Figure 4 and Figure 5 As shown: the lifting structure 22 includes a length adjusting arm 221, which is arranged below the first rotating shaft 21. The length adjusting arm 221 includes an extension shaft 2211 and a sleeve 2212. The extension shaft 2211 is inserted in the sleeve 2212. The total length of the length adjusting arm 221 is adjusted by changing the length of the extension shaft 2211 extending out of the sleeve 2212. The upper and lower ends of the length adjusting arm 221 are respectively provided with a swing arm 222 and a lifting arm 223. The two ends of the swing arm 222 are respectively connected to the first rotating shaft 21 and the extension shaft 2211. The upper and lower ends of the lifting arm 223 are respectively connected to the end of the sleeve 2212 and the knitting head 23. The outer cover of the lifting arm 223 is provided with a first limiting structure 224. The first limiting structure 224 is used to keep the moving direction of the lifting arm 223 colinear with the axis of the knitting head 23.

[0040] When jacquard processing is performed on different webbings, the descending stroke of the knitting head 23 may be different. By setting the length adjusting arm 221, the first rotating shaft 21 drives the swing arm 222 to rotate when it rotates, and the swing arm 222 drives the knitting head 23 to rise and fall through the length adjusting arm 221 and the lifting arm 223. The descending stroke of the connection between the length adjusting arm 221 and the lifting arm 223 is the same as the descending stroke of the knitting head 23. When the swing arm 222, the length adjusting arm 221 and the lifting arm 223 are in the same line and the knitting head 23 is at the lowest point, if the descending stroke of the knitting head 23 still cannot meet the jacquard processing, the extension shaft 2211 is extended out of the sleeve 2212 at this time to increase the total length of the length adjusting arm 221. When the swing arm 222, the length adjusting arm 221 and the lifting arm 223 are in the same line, the current height of the knitting head 23 is lower than the original height, so that the knitting head 23 has a larger descending stroke, so that the knitting head 23 can reach a lower position, thereby expanding the processing range of the knitting machine.

[0041] Reference Figure 4 and Figure 5 As shown: the length adjustment arm 221 also includes a driving block 2213 and a first self-locking driving component 2214; one end of the driving block 2213 is connected to the extension shaft 2211, and the other end of the driving block 2213 extends out of the sleeve 2212, and a slide groove is provided on the sleeve 2212, and the slide groove limits the driving block 2213 from moving along the axial direction of the sleeve 2212; the first self-locking driving component 2214 is arranged on the outside of the sleeve 2212, and the first self-locking driving component 2214 drives the extension shaft 2211 to move through the driving block 2213.

[0042] The synchronous drive structure 3 will drive the knitting head 23 to move up and down at a high frequency. The extension shaft 2211 and the sleeve 2212 will be repeatedly subjected to the forces of moving away from and approaching each other. Therefore, during long-term use, the total length of the length adjustment arm 221 will change, resulting in a change in the descending stroke of the knitting head 23, affecting the quality and production efficiency of the product. By setting a drive block 2213 and a first self-locking drive assembly 2214, the first self-locking drive assembly 2214 uses a screw as a driving member, and there is self-locking between the screw and the drive block 2213. The self-locking mechanism between the screw and the drive block 2213 ensures that the adjusted length can be firmly locked, effectively avoiding the length change caused by vibration, wear and other factors during use, thereby ensuring the accuracy and stability of the descending stroke of the knitting head 23.

[0043] Reference Figure 6 and Figure 7As shown, the rigid transmission structure 34 includes a transmission plate 341, a transmission rod 342, a third rotating shaft 343, a rectangular block 344 and a transmission gear set 345; the transmission plate 341 is arranged on one side of the first driving wheel 321; one end of the transmission rod 342 is connected to the transmission plate 341, and the transmission rod 342 is perpendicular to the transmission plate 341, the other end of the transmission rod 342 passes through the rectangular frame 33 and is slidably connected to the rectangular frame 33, and the other end of the transmission rod 342 is provided with a limited sliding shaft 344. 421, the axis of the limiting sliding shaft 3421 is perpendicular to the axis of the transmission rod 342; the third rotating shaft 343 is arranged on one side of the first rotating shaft 21, and the middle part of the third rotating shaft 343 is connected to the rectangular frame 33; a strip groove 3441 is opened on the rectangular block 344, the limiting sliding shaft 3421 is slidably arranged in the strip groove 3441, and one end of the rectangular block 344 is connected to one end of the third rotating shaft 343; the transmission gear set 345 connects the third rotating shaft 343 with the first rotating shaft 21.

[0044] When one end of the synchronous driving structure 3 has two first rotating shafts 21, the third rotating shaft 343 is located between the two first rotating shafts 21, and the transmission gear set 345 has three gears, which are connected to the first rotating shaft 21, the third rotating shaft 343 and the first rotating shaft 21 in sequence, and the three gears are meshed in sequence. At this time, when the middle gear rotates, the two gears on both sides rotate in the same direction. When the transmission plate 341 moves away from the second rotating shaft 31, the transmission plate 341 pushes the transmission rod 342 to move along its axis, and the limiting sliding shaft 3421 moves along the strip groove 3441 of the rectangular block 344. Since the height of the limiting sliding block remains unchanged, the rectangular block 344 is driven The third rotating shaft 343 rotates around the axis of the third rotating shaft 343, and the third rotating shaft 343 drives the two second rotating shafts 31 to rotate through the transmission gear set 345. When the transmission plate 341 is close to the second rotating shaft 31, the transmission plate 341 pulls the transmission rod 342 to move along its axis, and the limiting slider pulls the rectangular block 344 to rotate around the axis of the third rotating shaft 343 through the strip groove 3441, so that the two second rotating shafts 31 are reset. Through the precise coordination of the transmission plate 341, the transmission rod 342, the third rotating shaft 343, the rectangular block 344 and the transmission gear set 345, efficient transmission from the synchronous drive structure 3 to the two first rotating shafts 21 is achieved.

[0045] Reference Figure 7 and Figure 8As shown: the rigid transmission structure 34 also includes two second limiting structures 346, which are respectively arranged at the two ends of the transmission plate 341. The second limiting structures 346 are used to keep the transmission plate 341 from moving in translation as a whole under the action of the first driving wheel 321. The second limiting structure 346 includes a guide column 3461, one end of the guide column 3461 is connected to the transmission plate 341, and the other end of the guide column 3461 is slidably connected to the rectangular frame 33. A reset spring 3462 is sleeved on the guide column 3461. On the top, the two ends of the return spring 3462 are respectively in contact with the rectangular frame 33 and the transmission plate 341, and the other end of the guide column 3461 is provided with a limiting ring 3463. When the two protruding ends of the first driving wheel 321 are respectively in contact with the two transmission plates 341, the transmission plates 341 squeeze the return spring 3462. When the two protruding ends of the first driving wheel 321 are respectively separated from the two transmission plates 341, the return spring 3462 pushes the transmission plate 341 to move, and the limiting ring 3463 limits the return distance of the transmission plate 341.

[0046] When the raised end of the first driving wheel 321 contacts one end of the transmission plate 341 and gradually moves to the middle and then to the other end, the transmission plate 341 may tilt due to uneven force. The tilted transmission plate 341 will reduce the force on the transmission rod 342, thereby affecting the transmission efficiency. By setting two second limiting structures 346, in the initial state, the return spring 3462 applies a force toward the second rotating shaft 31 to the transmission plate 341, and the limiting ring 3463 limits the movement distance of the transmission plate 341. When the first driving wheel 321 applies a force to the transmission plate 341, the two guide columns 3461 and the transmission rod 342 move at the same time, ensuring that the transmission plate 341 can maintain overall translation when subjected to the force of the first driving wheel 321, effectively preventing the occurrence of tilting, thereby improving the precision and accuracy of the transmission.

[0047] Reference Figure 7 and Figure 8 As shown, the rigid transmission structure 34 further includes a first roller 347 , and the first roller 347 is disposed in the middle of the transmission plate 341 .

[0048] During the rotation of the first driving wheel 321, sliding friction continuously occurs between the first driving wheel 321 and the transmission plate 341, resulting in greater wear between the first driving wheel 321 and the transmission plate 341. By setting the first roller 347, the first roller 347 needs to be far beyond the transmission plate 341, so that the first driving wheel 321 only contacts the first roller 347 during the rotation. During the rotation of the first driving wheel 321, the first roller 347 pushes the transmission plate 341 to move. At the same time, the first driving wheel 321 will drive the first roller 347 to rotate, so that relative rolling occurs between the first roller 347 and the first driving wheel 321. The resistance of rolling friction is much smaller than that of sliding friction. Therefore, when the first driving wheel 321 pushes the transmission plate 341 through the first roller 347, the required driving force is smaller and the transmission efficiency is higher. Compared with sliding friction, the degree of wear of rolling friction is greatly reduced, thereby extending the service life of the first driving wheel 321 and the transmission plate 341.

[0049] Reference Fig. 9 As shown: the driving wheel assembly 32 also includes a sleeve 322 and a second driving wheel 323; the sleeve 322 is slidably mounted on the end of the second rotating shaft 31, and the sleeve 322 is connected to the first driving wheel 321; the second driving wheel 323 is mounted on the sleeve 322, and the second driving wheel 323 has two symmetrically arranged protrusions, and the base circle of the second driving wheel 323 has the same diameter as the base circle of the first driving wheel 321.

[0050] When the descending stroke of the knitting head 23 increases, due to the increase in the total length of the length adjustment arm 221, after the first rotating shaft 21 drives the swing arm 222 to rotate to the maximum angle, the length adjustment arm 221 drives the knitting head 23 to move upward for a short distance, and the knitting head 23 cannot be lifted to a higher position, which affects the jacquard processing of the webbing. By providing the sliding sleeve 322 and the second driving wheel 323, the two protrusions of the second driving wheel 323 exceed the two protrusions of the first driving wheel 321, and the second rotating shaft 31 drives the first driving wheel 321 to rotate through the sliding sleeve 322, so that the two protrusions of the first driving wheel 321 rotate to a vertical state, and at this time, the two protrusions of the second driving wheel 323 also In a vertical state, the sleeve 322 then slides along the second rotating shaft 31, causing the second driving wheel 323 to slide between the two transmission plates 341. When the second driving plate 3523 rotates, the two protrusions of the second driving plate 3523 push the two transmission plates 341 to move a distance greater than the distance the two protrusions of the first driving plate 3523 push the two transmission plates 341 to move, so that the moving distance of the transmission rod 342 increases, thereby increasing the rotation angle of the rectangular block 344, and the rotation angle of the swing arm 222 also increases, so that the upward movement path of the length adjustment arm 221 increases, thereby increasing the rising stroke of the knitting head 23 and avoiding the knitting head 23 from affecting the jacquard processing.

[0051] Reference Figure 3 , Fig. 9 and Fig.10 As shown: the synchronous drive structure 3 also includes an adjustment structure 35, the adjustment structure 35 includes two connecting structures 351 and an opening and closing structure 352; the two connecting structures 351 are respectively connected to the two driving wheel assemblies 32; the opening and closing structure 352 is arranged between the two connecting structures 351, and the opening and closing structure 352 drives the two driving wheel assemblies 32 to approach or move away from each other through the two connecting structures 351, and the opening and closing structure 352 includes two second self-locking drive assemblies 3521 and two moving blocks 3522, the second self-locking drive assembly 3521 is arranged between the two connecting structures 351, and the two moving blocks 3522 are respectively arranged at the two ends of the second self-locking drive assembly 3521, and the second self-locking drive assembly 3521 can drive the two moving blocks 3522 to approach or move away from each other, and driving plates 3523 are arranged at both ends of the moving blocks 3522, and the two ends of the driving plate 3523 are respectively connected to the moving blocks 3522 and the connecting structure 351.

[0052] Through the design of the opening and closing structure 352, the distance between the two driving wheel assemblies 32 can be automatically adjusted according to needs, so as to select a suitable driving wheel to cooperate with the first roller 347 or other matching parts. At the same time, when the second rotating shaft 31 drives the driving wheel assembly 32 to rotate, the driving wheel assembly 32 will vibrate, so that the driving wheel assembly 32 will move along the second rotating shaft 31, causing the selected suitable driving wheel to disengage from the first roller 347. Therefore, the introduction of the second self-locking driving assembly 3521 ensures that the two moving blocks 3522 can be locked after being adjusted to the appropriate position to prevent position displacement caused by vibration or external force, thereby achieving the fixed adjusted position of the two driving wheels.

[0053] Reference Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown: the connection structure 351 includes a connection disk 3511, a connection plate 3512 and a second roller 3513; the middle part of the connection disk 3511 is connected to one end of the sliding sleeve 322, and a V-shaped ring groove is provided on the connection disk 3511, and the V-shaped ring groove shrinks toward the axis of the connection disk 3511; the connection plate 3512 is arranged parallel to one side of the connection disk 3511; there are a plurality of second rollers 3513, and the plurality of second rollers 3513 are arranged in a ring array on the connection plate 3512, and the second rollers 3513 are provided with V-shaped protrusions around them, and the V-shaped protrusions cooperate with the V-shaped ring grooves.

[0054] When the opening and closing structure 352 adjusts the position of the sleeve 322 on the second rotating shaft 31 through the connecting structure 351, the connecting structure 351 needs to have the ability to apply tension and thrust to the sleeve 322. When the second rotating shaft 31 drives the sleeve 322 to rotate, the connecting structure 351 cannot interfere with the rotation of the sleeve 322. Therefore, a connecting disk 3511, a connecting plate 3512 and a second roller 3513 are provided. The connecting disk 3511 is connected to the sleeve 322. When the sleeve 322 rotates, the connecting disk 3511 is driven to rotate. A plurality of second rollers 3513 surround the connecting disk 3511. By utilizing the cooperation of the V-shaped ring groove and the V-shaped protrusion, the connecting structure 351 has the ability to apply tension and thrust to the sleeve 322. At the same time, when the sleeve 322 rotates, the connecting structure 351 will not interfere with the rotation of the sleeve 322, thereby ensuring that the sleeve 322 can smoothly rotate along the second rotating shaft 31, thereby improving the overall performance and stability of the drive system.
