[0002] A carbon fiber multi-axial warp knitting machine is a high-end textile equipment for producing high-performance composite material preforms. Through the coordinated cooperation of multiple weft insertion systems and loop-forming mechanisms, it can achieve precise laying and stitching of carbon fiber layers in multiple directions such as 0°, ±45°, 90°, etc., to form a fabric with a multi-dimensional reinforcement structure. The existing carbon fiber warp knitting machines are only provided with one creel. After the creel is used up, it is necessary to stop the machine to replace the creel, resulting in an extended processing cycle and affecting production efficiency.

[0003] For this reason, Chinese Patent with the authorization announcement number CN118109957B discloses a double-creel carbon fiber warp knitting machine, which is provided with a base assembly, a double-creel assembly and a driving assembly.

When the material on the unwinding bobbin on the first creel is used up and during material change, a third driving member drives the rotating frame to rotate to a suitable angle, and a second driving member drives the second air shaft to rotate, driving the second creel to rotate. The unwinding bobbin of the second creel quickly enters the working state, and the double creels perform quick material change.

Detailed implementation mode

[0031] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0032] Refer to Figures 1 - 3 : Carbon fiber multi-axial warp knitting machine, including a switching mechanism 1 and a driving mechanism 2; the switching mechanism 1 includes a mounting frame 11, a disc head 12, a pushing frame 13 and a first rotary driving assembly 14; an arc-shaped guide rail is provided on the mounting frame 11; a first rotating shaft 121 is rotatably arranged on the disc head 12, a first bearing 122 is sleeved on the first rotating shaft 121, and the first bearing 122 is in sliding fit with the arc-shaped guide rail on the mounting frame 11; the pushing frame 13 is rotatably arranged on the mounting frame 11, a linear guide rail is provided on the pushing frame 13, and the first bearing 122 is in sliding fit with the linear guide rail; the first rotary driving assembly 14 is used to drive the pushing frame 13 to rotate; the driving mechanism 2 is used to drive the disc head 12 to rotate.

[0033] The present invention realizes the function of automatically controlling the switching of the turret 12 through the switching mechanism 1 and the driving mechanism 2, and achieves the effect of controlling the cyclic supply of multiple turrets 12 by pushing the turret 12 to move through the rotatable push frame 13. When moving the specified turret 12 to the working position, the driving mechanism 2 is controlled to be connected to the turret 12 at the working position, and then the turret 12 is driven to rotate by the driving mechanism 2 to perform the unwinding operation. By controlling the length of the arc-shaped guide rail, multiple turrets 12 can be placed on the mounting frame 11 at the same time, and through the connection and separation of the driving mechanism 2 and the turret 12, the effect of sequentially driving multiple turrets 12 to rotate by one driving mechanism 2 is achieved, avoiding problems such as difficult installation and increased cost caused by setting multiple driving sources, and solving the problem that the installation amount of the turrets 12 is limited in traditional equipment because corresponding numbers of driving sources need to be provided according to the turrets 12. A chassis is provided at the bottom of the mounting frame 11, and the mounting frame 11 is connected to the chassis through a rod. The first rotation driving assembly 14 includes a first rotation driver 141 and a second rotating shaft 142. The first rotation driver 141 is provided on the mounting frame 11, the second rotating shaft 142 is rotatably provided on the mounting frame 11, the push frame 13 is sleeved on the second rotating shaft 142, and the driving end of the first rotation driver 141 is in transmission connection with the second rotating shaft 142 through a transmission belt. A controller for human-machine interaction is provided on the mounting frame 11. The first rotation driver 141 is preferably a servo motor, and the servo motor is electrically connected to the controller. Four turrets 12 are provided on the mounting frame 11, four linear guide rails are provided on the push frame 13, and the first bearings 122 of the four turrets 12 are respectively in sliding fit with the four linear guide rails. And the four linear guide rails on the push frame 13 are circularly arranged around the axis of the second rotating shaft 142.

[0034] After the working turret 12 is used up, first disconnect the connection between the driving mechanism 2 and the working turret 12. Then, a signal is sent to the first rotation driver 141 through the controller. The first rotation driver 141 drives the second rotating shaft 142 to rotate through the transmission belt. The second rotating shaft 142 drives the push frame 13 to rotate. The push frame 13 pushes the turret 12 to move along the arc-shaped guide rail on the mounting frame 11 through the cooperation of the linear guide rail and the first bearing 122. So that the four turrets 12 move simultaneously until the next turret 12 moves to the working position. Then, the driving mechanism 2 is controlled to be connected to the working turret 12, and the turret 12 is driven to rotate by the driving mechanism 2 to perform the unwinding operation.

[0035] Refer to Figure 1 、 Figures 4 - 6: The driving mechanism 2 includes a connecting component 21 and a second rotary driving component 22; a connecting disk 211 is sleeved on each first rotating shaft 121. The connecting component 21 includes a docking disk 212, and the docking disk 212 is in transmission connection with the driving end of the second rotary driving component 22. After the connecting disk 211 abuts against the docking disk 212, the docking disk 212 can drive the connecting disk 211 to rotate; an auxiliary control mechanism 3 for controlling the movement of the docking disk 212 is provided on the mounting frame 11.

[0036] The present invention realizes the function of driving the disk head 12 to move through the connecting component 21 and the second rotary driving component 22, and at the same time controls the movement of the docking disk 212 through the auxiliary control mechanism 3 to achieve the effect of connecting and disconnecting the driving mechanism 2 and the disk head 12. When replacing the disk head 12, first control the docking disk 212 to separate from the connecting disk 211 through the auxiliary control mechanism 3, and then drive the pushing frame 13 to rotate through the first rotary driving component 14, so that the next disk head 12 moves to the working position. Then control the docking disk 212 to abut against the connecting disk 211 on the disk head 12 at the working position through the auxiliary control mechanism 3, and then drive the docking disk 212 to rotate through the second rotary driving component 22. The docking disk 212 drives the connecting disk 211 to rotate. Furthermore, the first rotating shaft 121 and the disk head 12 are driven to rotate through the connecting disk 211. A docking block 2121 and a first elastic member 2122 are provided on the docking disk 212. The docking block 2121 is slidably mounted on the docking disk 212, and both ends of the first elastic member 2122 are connected to the docking block 2121 and the docking disk 212 respectively. A docking groove 2111 matching with the docking block 2121 is formed on the connecting disk 211. The second rotary driving component 22 includes a second rotary driver 221, a support 222 and a transmission shaft 223. The second rotary driver 221 is arranged on the mounting frame 11, the support 222 is connected to the mounting frame 11, the transmission shaft 223 is rotatably arranged on the support 222, and the transmission shaft 223 is in transmission connection with the docking disk 212.

[0037] When replacing the disc head 12, the auxiliary control mechanism 3 is used to control the docking disc 212 to move away from the connecting disc 211 until the docking disc 212 is separated from the connecting disc 211, disconnecting the connection of the connection component 21. Then, the first rotation drive 141 drives the second rotating shaft 142 to rotate. The second rotating shaft 142 drives the pushing frame 13 to rotate, and the pushing frame 13 pushes a plurality of disc heads 12 to move. After the next disc head 12 moves to the working position, the auxiliary control mechanism 3 is used to control the docking disc 212 to move towards the connecting disc 211. After the docking disc 212 abuts against the connecting disc 211, the second rotation drive assembly 22 drives the connecting disc 211 to rotate. As the connecting disc 211 rotates, when the docking block 2121 is aligned with the docking groove 2111, the docking block 2121 is inserted into and engaged with the docking groove 2111 under the elastic force of the first elastic member 2122. Through the cooperation of the docking block 2121 and the docking groove 2111, the docking disc 212 drives the connecting disc 211 to rotate, and the connecting disc 211 drives the first rotating shaft 121 and the disc head 12 to rotate.

[0038] Refer to Figures 1 - 4 : An induction mechanism 4 is provided on the mounting frame 11. The induction mechanism 4 includes an induction component 41 and a transmission component 42; when the disc head 12 moves to the working position, it presses the induction component 41, and the induction component 41 drives the auxiliary control mechanism 3 through the transmission component 42.

[0039] The present invention realizes the function of automatically controlling the movement of the docking disc 212 through the induction component 41 and the transmission component 42. During the process of the pushing frame 13 pushing the disc head 12 to move, when the next disc head 12 moves to the working position, it presses the induction component 41. The induction component 41 transmits the torque to the auxiliary control mechanism 3 through the transmission component 42, and the auxiliary control mechanism 3 controls the docking disc 212 to approach the connecting disc 211, so that the docking disc 212 abuts against the connecting disc 211, completing the connection between the drive mechanism 2 and the working disc head 12. When replacing the disc head 12, first, the auxiliary control mechanism 3 is used to control the separation of the docking disc 212 from the connecting disc 211, and then the first rotation drive assembly 14 drives the pushing frame 13 to rotate, and the pushing frame 13 pushes the disc head 12 to move. When the next disc head 12 approaches the working position, it presses the induction component 41. The induction component 41 transmits the torque to the auxiliary control mechanism 3 through the transmission component 42, and the auxiliary control mechanism 3 controls the docking disc 212 to approach the connecting disc 211, so that the docking disc 212 abuts against the connecting disc 211. After completing the connection between the drive mechanism 2 and the working disc head 12, the second rotation drive assembly 22 is used to drive the disc head 12 to rotate for the unwinding operation.

[0040] Refer to Figure 4 and Figure 8: The sensing component 41 includes a sensing rod 411 and a second elastic member 412; the sensing rod 411 is slidably arranged on the mounting bracket 11, and the sensing rod 411 is in transmission connection with the transmission component 42; both ends of the second elastic member 412 are respectively connected to the sensing rod 411 and the mounting bracket 11.

[0041] The present invention realizes the function of sensing whether the disc head 12 moves to the working position through the sensing rod 411 and the second elastic member 412. A graphite gasket is provided on the side of the sensing rod 411 close to the disc head 12, and the lubrication and wear resistance effects of the graphite gasket reduce the wear between the connecting disc 211 and the sensing rod 411. When the first rotary drive component 14 drives the push frame 13 to rotate, the push frame 13 pushes the disc head 12 to move along the arc-shaped guide rail on the mounting bracket 11. When the disc head 12 approaches the working position, the connecting disc 211 on the first rotating shaft 121 pushes the sensing rod 411, the second elastic member 412 contracts, and the sensing rod 411 drives the auxiliary control mechanism 3 through the transmission component 42 during movement, and the auxiliary control mechanism 3 controls the docking disc 212 to move away from the connecting disc 211. Furthermore, the effect of automatically controlling the connection between the drive mechanism 2 and the disc head 12 is achieved when replacing the disc head 12.

[0042] Refer to Figure 4 and Figure 8 : A guide frame 111 is provided on the mounting bracket 11, and an extension rod 4111 is provided on the sensing rod 411, and the extension rod 4111 is in sliding fit with the guide frame 111.

[0043] The present invention realizes the function of guiding the movement of the sensing rod 411 through the guide frame 111 and the extension rod 4111. When the connecting disc 211 on the disc head 12 pushes the sensing rod 411 to move, the movement of the sensing rod 411 is guided through the cooperation of the extension tube on the sensing rod 411 and the guide frame 111, and the sensing rod 411 can move along the specified path. When replacing the disc head 12, the first rotary drive component 14 drives the push frame 13 to rotate, the push frame 13 pushes the disc head 12 to move, so that the disc head 12 is separated from the sensing rod 411, and the sensing rod 411 is reset under the elastic force of the second elastic member 412. Through the arrangement of the extension rod 4111, the sensing rod 411 can always be in sliding fit with the guide frame 111 during movement.

[0044] Refer to Figure 1 、 Figure 9 and Figure 10 : The auxiliary control mechanism 3 includes a locking component 31, a control component 32, an elastic pushing component 33 and a linear driver 34; the locking component 31 is used to limit the movement of the docking disc 212; the control component 32 is used to release the movement restriction of the docking disc 212 by the locking component 31; the elastic pushing component 33 is used to push the docking disc 212 towards the connecting disc 211; the linear driver 34 is used to control the reset of the docking disc 212.

[0045] The present invention realizes the function of controlling the movement of the docking disk 212 through the locking assembly 31, the control assembly 32 and the elastic pushing assembly 33. The linear drive 34 is preferably a linear cylinder, which is electrically connected to the controller. When the disk head 12 is replaced, the controller sends a signal to the linear drive 34, and the linear drive 34 drives the docking disk 212 to reset, so that the docking disk 212 is separated from the connecting disk 211. At this time, the locking assembly 31 limits the movement of the docking disk 212 to prevent the docking disk 212 from extending under the elastic force of the elastic pushing assembly 33. Then, the push frame 13 is driven to rotate through the first rotating drive component 14, and the push frame 13 pushes the disk head 12 to move. When the next disk head 12 moves to the working position, the disk head 12 squeezes the sensing rod 411, and the sensing rod 411 drives the control component 32 through the transmission component 42. The control component 32 releases the movement restriction of the docking plate 212 by the locking component 31. The docking plate 212 moves toward the direction close to the connecting plate 211 under the thrust of the elastic pushing component 33, so that the docking plate 212 abuts against the connecting plate 211, completing the transmission connection between the driving mechanism 2 and the disk head 12.

[0046] Reference Figure 4 and Figure 7 : The transmission assembly 42 includes a transmission frame 421 and a second bracket 422; the transmission frame 421 is connected to the sensing rod 411; the second bracket 422 is connected to the transmission frame 421, and the second bracket 422 is transmission-connected to the auxiliary control mechanism 3.

[0047] The present invention realizes the function of driving the auxiliary control mechanism 3 when the sensing rod 411 moves through the transmission frame 421 and the second bracket 422. When the connection disk 211 on the disk head 12 pushes the sensing rod 411, the sensing rod 411 drives the second bracket 422 to move through the transmission frame 421. The second bracket 422 drives the control component 32 when moving, and the control component 32 releases the movement restriction of the locking component 31 on the docking disk 212. The docking disk 212 moves toward the connection disk 211 under the pushing action of the elastic pushing component 33, so that the docking disk 212 abuts against the connection disk 211, completing the connection between the driving mechanism 2 and the working disk head 12.

A second bearing is provided on the first bracket 331, and a third rotating shaft 224 is inserted into the second bearing. The transmission shaft 223 is drivingly connected to the third rotating shaft 224 through a transmission belt.

[0050] When the control assembly 32 releases the movement restriction of the push ring 333 by the locking assembly 31, the push ring 333 moves under the elastic force of the third elastic member 332, and the movement of the push ring 333 is guided by the guiding action of the extension rod 3331. When the push ring 333 moves, it drives the docking plate 212 to move until the docking plate 212 abuts against the connection plate 211.

[0051] Refer to Figures 9 - 11 : The locking assembly 31 includes a connection seat 311 and a clamping block 312; the connection seat 311 is connected to the first bracket 331, and a fourth elastic member 3111 is provided on the connection seat 311; the clamping block 312 is slidably mounted on the connection seat 311, and both ends of the fourth elastic member 3111 are respectively connected to the clamping block 312 and the connection seat 311; a card slot cooperating with the clamping block 312 is provided on the extension rod 3331 of the push ring 333.

A limiting block is provided on the side of the extension rod 3331 away from the push ring 333, and a frame for pushing the extension rod 3331 to move is connected to the driving end of the linear actuator 34. When the linear actuator 34 controls the push ring 333 to reset, the linear actuator 34 pushes the extension rod 3331 to move through the frame, the extension rod 3331 drives the push ring 333 to move, and the push ring 333 drives the docking plate 212 to move, so that the docking plate 212 is separated from the connection plate 211. When the clamping block 312 on the connection seat 311 is aligned with the card slot on the extension rod 3331, the clamping block 312 is inserted and cooperated with the card slot under the elastic force of the fourth elastic member 3111, thereby restricting the movement of the push ring 333. The reset actions of the push ring 333 and the docking plate 212 are completed.

[0053] Refer to Figures 9 - 11 : The control assembly 32 includes a push plate 321 and a fifth elastic member 322. A plug rod 3211 is connected to the push plate 321. A guiding groove 3121 is provided on the clamping block 312, and the plug rod 3211 is inserted and cooperated with the guiding groove 3121; both ends of the fourth elastic member 3111 are respectively connected to the push plate 321 and the connection seat 311.

[0054] The present invention realizes the function of releasing the movement restriction of the locking assembly 31 on the push ring 333 through the push plate 321, the insertion rod 3211 and the fifth elastic member 322. The second bracket 422 is provided with a wedge block 4221 for pushing the push plate 321. When the disk head 12 moves, it pushes the sensing rod 411, and the sensing rod 411 drives the wedge block 4221 to move through the transmission frame 421 and the second bracket 422, and the wedge block 4221 squeezes the push plate 321. The fifth elastic member 322 shrinks under the squeezing action, and the push plate 321 drives the insertion rod 3211 to move, and squeezes the card block 312 through the insertion rod 3211, and then pushes the card block 312 out of the card slot. After the card block 312 is separated from the card slot, the movement restriction on the push ring 333 is released. The push ring 333 moves under the elastic force of the third elastic member 332 , and then drives the docking plate 212 to move toward the connecting plate 211 through the push ring 333 until the docking plate 212 abuts against the connecting plate 211 .

[0055] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
