The second push rod device 231 can push the lifting plate 234 to drive the cutting blade 235 to cut the material 9 on the top surface of the cutting table 211.

[0038] Specifically, the second push rod device 231 is provided with a cylinder interface.

Working principle of cutting assembly 23: Under the action of feeding assembly 22, a section of the pulled material 9 is conveyed between cutting assembly 23 and cutting table 211. Then, the first force application assembly 33 and the second force application assembly 34 clamp the end of the pulled material 9 near the clamping mechanism 3. The guide rail assembly 31 drives the frame 32 to move the first force application assembly 33 and the second force application assembly 34 away from the cutting mechanism 2. At the same time, the pulled material 9 is also moved a short distance until the distance between the end of the pulled material 9 near the clamping mechanism 3 and the cutting table 211 is equal to the processing length of the pulled material 9 (that is, the pulled material 9 is processed into a bag shape).

[0047] The working principle of the third force application component 35 and the fourth force application component 36: The first gripper group 334, the second gripper group 344, the third gripper group 355, and the fourth gripper group 365 are located on the same horizontal plane, with the third gripper group 355 located at one end of the fifth guide rail 3541 near the cutting mechanism 2, and the fourth gripper group 365 located at one end of the sixth guide rail 3641 near the cutting mechanism 2.

The eighth driving component 3651 drives the fourth gripper head 3652 to clamp the middle area of ​​the pull material 9 near the clamping mechanism 3. (Based on the clamping of the pull material 9 by the first force application component 33 and the second force application component 34, the additional clamping of the pull material 9 by the third force application component 35 and the fourth force application component 36 provides a more stable power for the clamping mechanism 3 to drive the pull material 9 for conveying until the pull material 9 is cut off by the cutting mechanism 2.) After the pull material 9 is cut off, the seventh driving component 3551 drives... The third gripper head 3552 releases its grip on the material 9; the eighth drive unit 3651 drives the fourth gripper head 3652 to release its grip on the material 9; the fifth push rod device 351 pushes the first lifting support 354 to raise the third gripper group 355; the sixth push rod device 361 pushes the second lifting support 364 to raise the fourth gripper group 365. Simultaneously, the first lifting support 354 drives the third gripper group 355 to slide along the fifth guide rail 3541 away from the cutting mechanism 2. The second lifting support 364 drives the fourth gripper assembly 365 to slide along the sixth guide rail 3641 away from the cutting mechanism 2, providing working space for the subsequent flipping of the pulling material 9 by the first force application component 33 and the second force application component 34. Finally, when the threading mechanism 4 completes the threading and chaining work of the pulling material 9, the guide rail assembly 31 drives the frame 32 to drive the third force application component 35 and the fourth force application component 36 back to their original positions, and at the same time, the various structures in the third force application component 35 and the fourth force application component 36 are also reset.

[0048] Please see Figure 8 The clamping mechanism 3 also includes a fifth force-applying component 37 disposed between the first guide rail device 311 and the second guide rail device 312. The fifth force-applying component 37 includes a first support beam 371, a seventh push rod device 372, a support plate 373, and a mounting foot 374.

The seventh push rod device 372 can push the support plate 373 to rise and fall along the guide limit posts 375. The working principle of the fifth force application component 37: When the guide rail assembly 31 drives the frame 32 to move the first force application component 33 and the second force application component 34 away from the cutting mechanism 2, the seventh push rod device 372 pushes the support plate 373 to rise along the guide limit post 375. When the first force application component 33 and the second force application component 34 flip the pull material 9, the lower side of the cut pull material 9 is on the top surface of the support plate 373. At this time, the support plate 373 can provide support for the pull material 9 and prevent the pull material 9 from undergoing other deformations in the subsequent threading and chain joining work (there is a probability that the chain tooth row 8 will not be aligned with the tooth cavity of the pull head 7, resulting in manual stoppage for intervention). Finally, the seventh push rod device 372 pushes the support plate 373 back to its original position.

The first slider push rod 4116 pushes the slider push plate 4115 along the seventh guide rail 4114A to push the slider 7 to the slider clamp 4124 (before the first slider push rod 4116 pushes the slider 7, the slider clamp 4124 is pre-rotated until the slider clamp 4124 and the slider push plate 4115 are aligned).

The bidirectional cylinder 4341 is provided with a cylinder interface, and the two output ends of the bidirectional cylinder 4341 are respectively connected to the first transmission component 4342 and the second transmission component 4342. Two transmission components 4343 are fixedly connected. The first chain closing mold 4344 and the second chain closing mold 4345 are fixedly connected to the first transmission component 4342 and the second transmission component 4343, respectively. The bidirectional cylinder 4341 can synchronously drive the first transmission component 4342 and the second transmission component 4343 to drive the first chain closing mold 4344 and the second chain closing mold 4345 to close (i.e., the first chain closing mold 4344 moves toward the second chain closing mold 4345 and the second chain closing mold 4345 moves toward the first chain closing mold 4344). Working principle of upper mold assembly 43: The pull head conveyor 412 conveys the pull head 7 provided by the pull head storage platform 411 to the upper side of the eighth pusher device 422. The ninth pusher device 425 pushes the rotating module 424 to rotate toward the fixed module 423. The top of the rotating module 424 cooperates with the top of the fixed module 423 to clamp the pull head 7. The pull head conveyor 412 returns to its original position. The eighth pusher device 422 pushes the fixed module 423 to drive the rotating module 424, the ninth pusher device 425, and the pull head 7 to the lower side of the upper mold assembly 43. The top surface of the pull head 7 is snapped into the snap-fit ​​cavity 4331. The guide rail drive device 315 drives the frame 32 on the first guide rail platform 313 and the second guide rail platform 314 to drive the first force application component 33 and the second force application component 34 to continue moving away from the cutting mechanism 2. The pull head 7, which is fixed by the clamping cavity 4331, the fixing module 423, and the rotating module 424, moves in the direction of the material being pulled. Under the conveying action of the clamping mechanism 3 on the material being pulled, the pull head 7 is successfully inserted into the chain tooth row 8 in the material being pulled. Then, the lower die assembly 42 returns to its original position and the bidirectional cylinder 4341 is activated. The bidirectional cylinder 4341 drives the first chain closing die 4344 and the second chain closing die 4345 to close. Under the conveying action of the clamping mechanism 3 on the material being pulled, the side of the first chain closing die 4344 facing the second chain closing die 4345 limits the chain tooth row 8, and the side of the second chain closing die 4345 facing the first chain closing die 4344 also limits the chain tooth row 8. The chain tooth row 8 completes the chain closing between the first chain closing die 4344 and the second chain closing die 4345. Finally, the chain closing device 434 returns to its original position.

[0055] The working principle of the fully automatic cutting, threading, and chain-joining integrated machine: 1. The pressing device 223 clamps the pulled material 9. The first pusher device 221 pushes the feeding platform 222 and the pressing device 223 to transport the pulled material 9 between the cutting assembly 23 and the cutting table 211. Then, the pressing device 223 releases the clamping of the pulled material 9. The first pusher device 221 pushes the feeding platform 222 and the pressing device 223 back to their original positions. The first gripper group 334, the second gripper group 344, the third gripper group 355, and the fourth gripper group 365 clamp the end of the pulled material 9 near the clamping mechanism 3. The guide rail drive device 315 drives the first guide rail platform 313. The frame 32 on the second guide rail platform 314 drives the first force application component 33, the second force application component 34, the third force application component 35, and the fourth force application component 36 to move away from the cutting mechanism 2 until the distance between the end of the pull material 9 near the clamping mechanism 3 and the cutting table 211 is equal to the processing length of the pull material 9. Then, the second push rod device 231 pushes the cutting blade 235 to cut the pull material 9 on the cutting table 211 and immediately drives the cutting blade 235 back to its original position. The guide rail drive device 315 is restarted, and the cut pull material 9 is taken out of the cutting mechanism 2 by the clamping mechanism 3. 2. The third gripper group 355 and the fourth gripper group 365 release their gripping of the material 9. The fifth pusher device 351 and the sixth pusher device 361 respectively drive the third gripper group 355 and the fourth gripper group 365 to rise. Taking the installation position of the cutting mechanism 2 on the machine body 1 as the observation origin, the first sliding support 332 drives the first rotating support 333 to rotate the first gripper group 334 counterclockwise by 90°, and the second sliding support 342 drives the second rotating support 343 to rotate the second gripper group 344 clockwise by 90°. At the same time, the third... The three-push rod device 331 pushes the first sliding support 332, causing the first rotating support 333 and the first gripper group 334 to slide a distance closer to the second sliding support 342. The fourth push rod device 341 pushes the second sliding support 342, causing the second rotating support 343 and the second gripper group 344 to slide a distance closer to the first sliding support 332. At this time, the material 9 is processed into a bag shape. The seventh push rod device 372 pushes the support plate 373 to rise, and the support plate 373 provides support for the lower side of the material 9 that has been processed into a bag shape. 3. The pull head conveyor 412 conveys the pull head 7 provided by the pull head storage platform 411 to the upper side of the eighth pusher device 422. The ninth pusher device 425 pushes the rotating module 424 to rotate toward the fixed module 423. The top of the rotating module 424 cooperates with the top of the fixed module 423 to clamp the pull head 7. The pull head conveyor 412 returns to its original position. The eighth pusher device 422 pushes the fixed module 423, causing the rotating module 424, the ninth pusher device 425, and the pull head 7 to rise to the lower side of the upper mold assembly 43. The top surface of the pull head 7 is snapped into the snap-fit ​​cavity 4331. The guide rail drive device 315 drives the frame 32 on the first guide rail platform 313 and the second guide rail platform 314 to drive the first force application component 33 and the second force application component 34 to continue moving away from the cutting mechanism 2. Under the conveying action of the clamping mechanism 3 on the pull material 9, the material is snapped into the snap-fit ​​cavity 4331. 31. The pull head 7, which is fixed by the fixing module 423 and the rotating module 424, is successfully threaded onto the chain tooth row 8 in the pull material 9. Then, the lower die assembly 42 returns to its original position, and the bidirectional cylinder 4341 is activated. The bidirectional cylinder 4341 drives the first chain closing die 4344 and the second chain closing die 4345 to close. Under the conveying action of the clamping mechanism 3 on the pull material 9, the chain tooth row 8, which is limited by the first chain closing die 4344 and the second chain closing die 4345, completes the chain closing between the first chain closing die 4344 and the second chain closing die 4345. Finally, the chain closing device 434 returns to its original position, the seventh push rod device 372 pushes the support plate 373 back to its original position, and the clamping mechanism 3 drives the pull material 9 to move to the upper side of the material cart 5. The first gripper group 334 and the second gripper group 344 release the gripping of the pull material 9. After the pull material 9 is threaded and closed, it falls into the material cart 5, and the clamping mechanism 3 returns to its original position.
