In the radial direction of the turntable 302, a gap is left between the first mounting plate 342a and the turntable 302, so as to avoid the first mounting plate 342a from interfering with the rotation of the turntable 302.

A second limit plate 342f is also arranged between the side wall of the chute 342b and the locking rod 342 c; the second stopper plate 342f serves to prevent the locking lever 342c from shaking or shifting within the sliding groove 342b, thereby allowing the locking lever 342c to be accurately inserted into the locking groove.

An adjusting bolt is connected between the second limiting plate 342f and the side wall of the chute 342b, and is used for adjusting the distance between the second limiting plate 342f and the locking rod 342 c.

In the embodiment, each main shaft 401 is connected with a second transmission shaft 411; the plurality of second transmission shafts 411 connected to the same set of main shafts 401 are set as one set.

The first group of spindles and the second group of spindles have the same structure, and one group of spindles is taken as an example for explanation. Wherein a second transmission shaft 411 close to the driving unit 200 is fixedly connected with a fourth gear 402; the fourth gear 402 is meshed with the second gear 208, so as to drive the corresponding main shaft 401 to rotate. A fourth transmission wheel 404 is also fixedly arranged on the second transmission shaft 411 provided with the fourth gear 402, so as to drive the fourth transmission wheel 404 to synchronously rotate. The other second transmission shafts 411 in the same group are respectively connected with a third transmission wheel 403 and a fourth transmission wheel 404. A third driving wheel 403 on a second transmission shaft 411 is in driving connection with the third driving wheel 403 on the subsequent second transmission shaft 411 through a second driving belt 405; the fourth transmission wheel 404 on a second transmission shaft 411 is in transmission connection with the fourth transmission wheel 404 on the previous second transmission shaft 411 through a second transmission belt 405. Thereby, the power of the driving unit 200 is gradually transmitted to the distal second transmission shaft 411; so that the driving unit 200 can drive the spindles 401 of the same group to rotate synchronously at a time.

The turntable 302 is further provided with a first tension wheel 406, and the first tension wheel 406 is used for adjusting the tightness degree of the second transmission belt 405 so as to realize smooth transmission of power.

As shown in fig. 10 and 11, a first guide sleeve 409 is disposed at a connection position of the second transmission shaft 411 and the turntable 302. The first guide sleeve 409 is fixedly connected with the turntable 302; a bearing is arranged between the second transmission shaft 411 and the first guide sleeve 409, so that the second transmission shaft 411 can smoothly rotate relative to the first guide sleeve 409.

One end of the second transmission shaft 411 close to the spindle 401 is provided with a clamping jaw 408 for clamping the spindle 401. One end of the second transmission shaft 411 close to the main shaft 401 is provided with a receiving cavity, and a piston block 410 is slidably arranged in the receiving cavity. Correspondingly, an airflow channel is arranged in the second transmission shaft 411, and one end of the airflow channel is communicated with the accommodating cavity; the other end of the air flow channel is connected with an air nozzle 407, and the air nozzle 407 is connected with a two-way connector 309; the piston block 410 is pushed to move by connecting a high-pressure air source.

The piston block 410 is provided with an inclined surface for the roller 408a to roll; the end of the ramp near the airflow path is spaced further from the axis of the piston block 410 than the other end of the ramp. By utilizing the lever principle, when high-pressure air flows in, the piston block 410 pushes one end of the clamping jaw 408 provided with the roller 408a to tilt gradually, so that one end of the clamping jaw 408 close to the spindle 401 is close to the spindle 401, and the effect of clamping the spindle 401 is realized. One end of the clamping jaw 408 close to the spindle 401 is provided with an adjusting bolt, so that the distance from the clamping jaw 408 to the spindle 401 is adjusted to clamp spindles 401 of different sizes.

The piston block 410 is further provided therein with an elastic member 412 and a first guide rod 414. One end of the first guide rod 414 extends out of the piston block 410 and abuts against the end surface of the main shaft 401. The elastic member 412 is sleeved on the first guiding rod 414; one end of the elastic element 412 is pressed against the inner wall of the piston block 410; the other end of the elastic member 412 abuts against a flange 414a of the first guide rod 414. Therefore, when no high-pressure air source is introduced, the piston block 410 is pushed to move away from the main shaft 401 under the action of the elastic element 412; thereby causing the jaws 408 to release the spindle 401. The elastic member 412 may be a spring, a flexible block, or the like.

And a return spring 413 is further arranged outside one end of the clamping jaw 408 far away from the main shaft 401, and the return spring 413 is arranged around the axis of the accommodating cavity. When the end of the jaw 408 having the roller 408a is tilted, the return spring 413 is elastically deformed to expand outward. When no high-pressure air source is introduced, under the action of the elastic force, the return spring 413 contracts to enable one end, provided with the roller 408a, of the clamping jaw 408 to move towards the direction close to the axis of the piston block 410, and enable one end, close to the spindle 401, of the clamping jaw 408 to tilt.

The cutting unit 600 includes a rotating plate 601 and a first adjusting assembly; one end of the rotating plate 601 is rotatably mounted on the fourth mounting plate 806 through the first rotating shaft 602a, so that the cutting unit 600 is rotatably mounted on the fourth mounting plate 806, and the angle between the cutting unit 600 and the main shaft 401 is adjustable.

As shown in fig. 13 and 15, the first adjusting assembly is used to adjust the rotation angle of the rotating plate 601. The first adjustment assembly includes a first drive member, a connecting rod, and a turning block 602 b. The first drive member is fixedly mounted on the fourth mounting plate 806; the first driving member is used for driving the connecting rod to move, and further driving the rotating plate 601 to rotate.

In this embodiment, the first driving member is a fourth motor 602 f; the connecting rod is a first lead screw 602 d. The first lead screw 602d is in threaded fit connection with the rotating block 602 b; the first lead screw 602d is disposed parallel to the rotating plate 601.

The second rotation shaft 602e is disposed perpendicular to the rotation plate 601.

When the fourth motor 602f is operated, the first lead screw 602d is driven to rotate. Since the rotating block 602b cannot rotate along with the first lead screw 602d, the rotating block 602b moves along the first lead screw 602d, and a driving force is applied to the rotating plate 601 to drive the rotating plate 601 to rotate; meanwhile, the rotating block 602b rotates around the second rotating shaft 602e to adapt to the direction of the first lead screw 602 d.

In other embodiments, the first driving member may also be a cylinder, and an output shaft of the cylinder is fixedly connected to the rotating block 602 b.

A slide rail is arranged on the rotating plate 601; the first mounting block 603 is provided with a sliding groove matched with the sliding rail. When the first mounting block 603 slides along the slide rail, the first mounting block 603 is close to or far away from the end of the rotating plate 601 where the first rotating shaft 602a is arranged.

As shown in fig. 16 and 17, a second adjusting assembly is further disposed on the rotating plate 601 for adjusting the relative position of the first mounting block 603 on the rotating plate 601. The second adjustment assembly includes a first seat 617 and a second lead screw 615. One end of the second lead screw 615 is fixedly connected with the first mounting block 603; the other end of the second screw 615 is connected with a first handle 616, and the first handle 616 is in threaded fit connection with the second screw 615.

First support 617 is located adjacent to an end of first handle 616; the first support 617 is connected to the first handle 616; the first abutment 617 functions to restrain the first handle 616.

In use, the first handle 616 is rotated without changing the relative position between the first handle 616 and the rotating plate 601. Under the effect of the threaded connection, the second lead screw 615 retracts or extends relative to the first handle 616, so as to drive the first mounting block 603 to move along the slide rail, and thus, the position of the first mounting block 603 on the rotating plate 601 is adjusted.

The driving assembly is fixedly mounted on an end of the first mounting block 603 away from the main shaft 401.

The other end of the coupler 612 is detachably connected with a sixth driving wheel 611; the sixth transmission wheel 611 is in transmission connection with the cutter 605 through a second transmission assembly.

When the shaft coupling 612 is connected to the sixth transmission wheel 611, the shaft coupling 612 drives the sixth transmission wheel 611 to rotate synchronously, and further drives the second transmission assembly to move to drive the cutter 605 to rotate, that is, the cutter 605 is driven to rotate by the driving assembly, so that the cutter 605 rotates actively relative to the material roll, and has active cutting force.

When the coupling 612 is separated from the sixth transmission wheel 611, the sixth transmission wheel 611 does not rotate with the coupling 612, and the driving assembly does not drive the cutter 605 to rotate. The cutter 605 then follows the roll rotation, the cutter 605 having a passive cutting force; in operation, relative rotation occurs between the sixth drive wheel 611 and the output shaft of the reducer.

The coupling 612 and the sixth driving wheel 611 can be connected through a bolt connection, a clamping connection and the like.

The cutter 605 is mounted to the end of the first mounting block 603 remote from the drive assembly. The third transmission shaft 622 extends perpendicularly to the extension direction of the slide rail on the rotating plate 601, so that the cutting edge of the cutter 605 faces the front end of the rotating plate 601, i.e. the end of the slide rail away from the driving assembly.

One end of the sleeve 608 close to the cutter 605 is provided with a cutter box 606 for accommodating the cutter 605; in operation, the cutter 605 rotates relative to the magazine 606. The end of the knife box 606 remote from the first mounting block 603 is provided with an opening through which the knife 605 protrudes, so that the knife 605 can contact the material roll to perform a cutting action.

The third drive shaft 622 is disposed through the magazine 606 and is fixedly coupled to the cutters 605 within the magazine 606. A pair of clamping plates 613 for clamping the cutter 605 is fixedly arranged on the third transmission shaft 622 so as to fix the cutter 605 on the third transmission shaft 622.

The second tension wheel 609 can change the direction of the third transmission belt while adjusting the tightness of the third transmission belt 614, so that the third transmission belt 614 can simultaneously drive six fifth transmission wheels 610 to synchronously rotate, and further drive six groups of cutters 605 to synchronously rotate to realize cutting action.

In other embodiments, the number of cutters 605 may be set according to the number of spindles 401, and the number of cutters 605 is the same as the number of spindles 401 in a group of spindles.

The cutter box 606 is further provided with a spray head 607, and the spray head 607 is used for spraying cold air to the cutter 605 so as to cool the cutter 605.

One end of the third screw 618 is connected with the slider 621 in a threaded fit manner; the other end of the third lead screw 618 is fixedly connected with a second handle 619. The other end of the sliding block 621 is fixedly connected with the shaft sleeve 608. A sliding cavity 603a for moving the sliding block 621 is arranged in the first mounting block 603; the slider 621 can slide in the sliding cavity 603a to move along the direction of the sliding rail on the rotating plate 601. The second support 620 is fixed at one end of the first mounting block 603 away from the cutter 605; the second support 620 is for supporting the restraining second handle 619.

In use, the second handle 619 is rotated to rotate the third lead screw 618, and under the action of thread fit, the third lead screw 618 and the sliding block 621 generate relative motion, so that the sliding block 621 drives the cutter 605 to move, and the position of the cutter 605 is adjusted.

In this embodiment, five sets of third adjusting assemblies are disposed on the first mounting block 603; the third adjusting components correspond to a group of cutters 605 from top to bottom respectively; accordingly, the relative positions of the upper five sets of cutters 605 and the first mounting block 603 are adjusted by the third adjusting assembly, respectively. The group of cutters 605 positioned at the lowermost part of the first mounting block 603 are directly and fixedly connected with the first mounting block 603, and the position of the first mounting block 603 is adjusted through the second adjusting component, so that the position of the group of cutters 605 at the lowermost part is adjusted. When the cutter 605 is aligned, the blade tip of the cutter 605 at the lowest position is aligned with the central axis of the first rotating shaft 602a by adjusting the second adjusting component; the third adjusting assembly is adjusted in sequence to align the five groups of cutters 605 above the third adjusting assembly in sequence.

In other embodiments, a third adjusting assembly is connected to a group of cutters 605 located at the lowest position of the first mounting block 603, so as to individually adjust the positions of the cutters 605 at the corresponding positions.

As shown in fig. 2, 20 and 21, the tumble cutting station further includes a follower unit 700, and the follower unit 700 is rotatably mounted on the third mounting bracket 802. The plane of rotation in which the follower rest unit 700 is located is parallel to the spindle 401; the follower holder unit 700 is provided at a position intermediate between the two sets of spindles 401. The follower unit 700 is used to support the main shaft 401 at the opposite side of the cutter 605, thereby preventing the cutter 605 from cutting the web due to elastic deformation of the main shaft 401 during operation.

The follower unit 700 includes a third cylinder 701 and a second stopper wheel 703. The second limiting wheel 703 is rotatably mounted on one side of the fifth mounting plate 702; the fifth mounting plate 702 is sequentially provided with five sets of second limiting wheels 703 from top to bottom. The second limiting wheel 703 is used for being tangent to the material roll, so that the elastic deformation of the main shaft 401 is avoided, and the rotation of the material roll driven by the main shaft 401 is not influenced.

The third cylinder 701 is rotatably connected with the lower end of the fifth mounting plate 702 through a fifth rotating shaft 706; the same end of the fifth mounting plate 702 connected with the third cylinder 701 is rotatably mounted on the third mounting frame 802 through a sixth rotating shaft 707; a third cylinder 701 is rotatably mounted on a third mount 802. The fifth mounting plate 702 can rotate around the sixth rotating shaft 707 by the third cylinder 701.

In this embodiment, the second limiting wheel 703 is rotatably connected to a connecting plate, and the connecting plate is fixedly mounted on the sixth motor 704. The output end of the sixth motor 704 is in threaded fit connection with the fifth mounting plate 702; therefore, the sixth motor 704 drives the second limiting wheel 703 to move so as to adjust the distance from the second limiting wheel 703 to the main shaft 401, thereby adapting to material rolls with different thicknesses. A third guide rod 705 is connected between the fifth mounting plate 702 and the sixth motor 704, and the third guide rod 705 is used for guiding and simultaneously plays a role in supporting the sixth motor 704.

In order to avoid the slippage between the transmission belt and the transmission wheel, the transmission wheel in the embodiment adopts a toothed wheel with teeth; correspondingly, the transmission belt is a gear belt matched with the corresponding toothed wheel.

In use, an operator sleeves the material roll on the main shaft 401, and adjusts the first adjusting component on the cutting unit 600 to enable the blade section of the cutter 605 to be perpendicular to the material roll; the cutter 605 is aligned by adjusting the second and third adjustment assemblies. The drive unit 200 is activated to rotate the spindle 401 with the roll. The operator can control the second clutch assembly to enable the driving assembly of the cutting unit 600 to supply power to the cutter 605 according to the material of the material roll, so as to select the cutter 605 to perform active cutting or passive cutting. Wherein, the follower rest unit 700 is tangent to the material roll, so as to avoid the main shaft 401 from generating elastic deformation. When cutting, the moving unit 800 controls the movement and feeding of the cutting unit 600.

When the cutting of the material roll on the group of spindles 401 is completed, the first clutch assembly of the driving unit 200 disconnects the driving unit 200 from the spindles 401. The tailstock unit 500 is separated from the main spindle 401.

Meanwhile, the follower holder unit 700 is rotated to make the follower holder unit 700 parallel to the main shaft 401, so that the main shaft 401 is prevented from being overturned; the moving unit 800 moves the cutting unit 600 away from the main shaft. The locking assembly of the flipping unit 300 is unlocked; the turntable 302 is rotated to drive the two groups of main shafts 401 to turn over, so that the position switching of the two groups of main shafts 401 is realized.
