[0042] See also Figure 1 to Figure 2The present application provides a paper sheet die-cutting feeding device 100, which includes a frame 10. Along the feeding direction a of the paper sheet die-cutting feeding device 100, the frame 10 is detachably mounted with an unwinding module 20, a paper tape transmission module 30, a paper tape die-cutting module 40 and a paper sheet transmission module 50. The unwinding module 20 is used to place a paper roll 200, and the paper sheet transmission module 50 is used to connect a paper cup forming machine. Among them, the paper tape 210 is transmitted from the unwinding module 20 to the paper tape die-cutting module 40 via the paper tape transmission module 30, and the paper tape die-cutting module 40 is used to cut the paper tape 210 into paper sheets 220, and the paper sheets 220 are transmitted to the paper cup forming machine via the paper sheet transmission module 50. By detachably integrating the unwinding module 20, the paper tape transmission module 30, the paper tape die-cutting module 40 and the paper sheet transmission module 50 on the frame 10, the paper sheet die-cutting and feeding device 100 has the functions of unwinding, die-cutting and feeding, and different specifications of the unwinding module 20, the paper tape transmission module 30, the paper tape die-cutting module 40 and the paper sheet transmission module 50 can be designed according to the requirements, thereby improving the compatibility of the paper sheet die-cutting and feeding device 100 with paper cup forming machines of different specifications. Moreover, the paper sheet 220 cut and formed by the paper tape die-cutting module 40 can be transmitted to the paper cup forming machine through the paper sheet transmission module 50, without the need for workers to carry the paper sheet 220, which is conducive to improving the feeding efficiency of the paper sheet 220 die-cutting and feeding device.

[0043] See also Figures 1 to 3 The unwinding module 20 includes a first rotating shaft 21, a second rotating shaft 22 and a bracket 23. One end of the bracket 23 is rotatably connected to the frame 10 through the first rotating shaft 21, and the other end is installed with the second rotating shaft 22. The second rotating shaft 22 is used to cover the paper supply roll 200; wherein, the height of the second rotating shaft 22 changes as the bracket 23 rotates around the first rotating shaft 21. In this way, the height of the second rotating shaft 22 can be adjusted by rotating the bracket 23 around the first rotating shaft 21 to different positions, thereby adjusting the height of the paper roll 200.

[0044] Specifically, the number of the brackets 23 is configured to be two, and the two brackets 23 are rotatably connected to the two ends of the frame 10 along the width direction through the first rotating shaft 21. Each bracket 23 is provided with a shaft fixing plate 231, and the two ends of the second rotating shaft 22 are rotatably passed through the two shaft fixing plates 231. The shaft fixing plates 231 are used to prevent the second rotating shaft 22 from accidentally tipping over.

[0045] The two ends of the second rotating shaft 22 are rotatably connected to the two brackets 23, and the second rotating shaft 22 is provided with two baffles 221, which are spaced apart along the axial direction of the second rotating shaft 22. It can be understood that the two baffles 221 are used to cooperate with clamping the paper roll 200 to prevent the paper roll 200 from moving left and right.

[0046] Furthermore, the unwinding module 20 further includes a support rod 25, one end of the support rod 25 is connected to the frame 10, and the other end is connected to the bracket 23, and the support rod 25 is configured to be retractable to drive the bracket 23 to rotate around the first rotating shaft 21. The support rod 25 is used to form a supporting effect between the frame 10 and the supporting bracket 23, and as the support rod 25 is extended and shortened, it can drive the bracket 23 to rotate around the first rotating shaft 21, thereby adjusting the height of the second rotating shaft 22.

[0047] Optionally, in one embodiment, the bracket 23 is configured to be L-shaped, and the support rod 25 is connected to one end of the L-shaped bracket 23 away from the first rotating shaft 21. The support rod 25 is configured to be extended and retracted by a hydraulic cylinder. As the support rod 25 is extended, the height of the second rotating shaft 22 and the paper roll 200 sleeved on the outer periphery of the second rotating shaft 22 increases; as the support rod 25 is shortened, the height of the second rotating shaft 22 and the paper roll 200 sleeved on the outer periphery of the second rotating shaft 22 decreases.

[0048] The unwinding module 20 further includes a stopper 26, which is movably connected to the bracket 23 along the width direction of the frame 10, and one end of the second rotating shaft 22 is installed on the frame 10 through the stopper 26. In this way, the installation position of the stopper 26 can be adjusted along the width direction of the frame 10, so that the position of the second rotating shaft 22 and the paper roll 200 can be adjusted left and right along the width direction of the frame 10.

[0049] Optionally, a groove 261 is formed on the limit block 26 , and the groove 261 extends along the length direction of the frame 10 . An adjustment flange 222 is formed at the end of the second rotating shaft 22 , and the adjustment flange 222 is snap-fitted with the groove 261 .

[0050] The unwinding module 20 further includes an adjusting member 27 and a guide rod 24, wherein the guide rod 24 is fixedly connected to the bracket 23 and extends along the width direction of the frame 10, and a limit block 26 is movably sleeved on the guide rod 24, wherein the limit block 26 is provided with a threaded hole, and the adjusting member 27 is provided with an external thread, and the adjusting member 27 is threadedly connected to the limit block 26. It can be understood that when the user rotates the adjusting member 27, the guide rod 24 limits the limit block 26 from rotating around the adjusting member 27, so that the limit block 26 can only move along the guide rod 24. Optionally, a hand wheel 271 is provided at one end of the adjusting member 27 away from the limit block 26, and the hand wheel 271 is used to facilitate the user to rotate the adjusting member 27.

[0051] The unwinding module 20 further includes a magnetic powder clutch 28 and a coupling 29, and the inner shaft of the magnetic powder clutch 28 is connected to the other end of the second rotating shaft 22 through the coupling 29. In this way, the magnetic powder clutch 28 unwinds the second rotating shaft 22 at a constant torque through the coupling 29, thereby controlling the tension of the paper tape 210 during unwinding.

[0052] Please refer again Figures 1 to 3The paper die-cutting and feeding device 100 also includes two support plates 60, which are respectively connected to both sides of the frame 10 along the width direction of the frame 10, and the paper tape transmission module 30, the paper tape die-cutting module 40 and the paper sheet transmission module 50 are respectively detachably installed on the two support plates 60.

[0053] See also Figures 4 to 5 The paper tape transmission module 30 includes a first paper feeding roller 31 and a second paper feeding roller 32 arranged at intervals along the feeding direction a. The first paper feeding roller 31 and the second paper feeding roller 32 are rotatably mounted on two support plates 60, respectively. The first paper feeding roller 31 is located below the second paper feeding roller 32 along the width direction of the frame 10. It can be understood that the first paper feeding roller 31 and the second paper feeding roller 32 respectively realize the paper tape 210 transmission by rotating.

[0054] The first paper feeding roller 31 includes a first active roller 311, a first driven roller 312, a first synchronous wheel 313, a second synchronous wheel 314, a first synchronous belt 315 and a first motor 316. The first synchronous wheel 313 is connected to the transmission shaft of the first motor 316, the second synchronous wheel 314 is connected to the first active roller 311, and the first synchronous wheel 313 and the second synchronous wheel 314 are connected by the first synchronous belt 315. As the transmission shaft of the first motor 316 rotates, the first active roller 311 can be driven to rotate, and the paper tape 210 passes between the first active roller 311 and the first driven roller 312.

[0055] The second paper feeding roller 32 includes a second active roller 321, a second driven roller 322, a third synchronous wheel 323, a fourth synchronous wheel 324, a second synchronous belt 325 and a second motor, wherein the third synchronous wheel 323 is connected to the transmission shaft of the second motor, the fourth synchronous wheel 324 is connected to the second active roller 321, and the third synchronous wheel 323 and the fourth synchronous wheel 324 are connected by the second synchronous belt 325. As the transmission shaft of the second motor rotates, the second active roller 321 can be driven to rotate, and the paper tape 210 passes between the second active roller 321 and the second driven roller 322.

[0056] The paper tape transmission module 30 further includes a plurality of guide shafts 33, which are located between the first paper feeding roller 31 and the second paper feeding roller 32, and each guide shaft 33 is fixedly mounted on two support plates 60. The guide shaft 33 is used to guide the paper tape 210 to change direction. Optionally, a paper tape 210 limiting ring 331 is provided at each end of the guide shaft 33, and the paper tape 210 limiting ring 331 is used to guide the paper tape 210 to prevent the paper tape 210 from running off or wrinkling.

[0057] Optionally, in one embodiment, the number of guide shafts 33 is configured to be two, one of which is located between the first paper feeding roller 31 and the second paper feeding roller 32 along the height direction of the frame 10, and the height of the other guide shaft 33 is consistent with the height of the second paper feeding roller 32. The paper tape 210 first passes between the first active roller 311 and the first driven roller 312, then first wraps around the guide shaft 33 located between the first paper feeding roller 31 and the second paper feeding roller 32, then wraps around the guide shaft 33 that is consistent with the height of the second paper feeding roller 32, and finally passes between the second active roller 321 and the second driven roller 322 and extends toward the paper tape die-cutting module 40.

[0058] The paper tape transmission module 30 further includes a limiting rod 34 . The limiting rod 34 is fixedly mounted on the support plate 60 and is located above the paper tape 210 . The limiting rod 34 is used to press down the paper tape 210 .

[0059] See also Figures 6 to 8 The paper tape die-cutting module 40 includes a first panel 41, a connecting bracket 42, a first connecting rod 43 and a shearing assembly 44. The first panel 41 is fixedly mounted between two support plates 60, the connecting bracket 42 is fixedly mounted to one of the support plates 60, the first connecting rod 43 is rotatably connected to the connecting bracket 42, and the shearing assembly 44 is connected to the first connecting rod 43; and as the first connecting rod 43 rotates around the connecting bracket 42, the shearing assembly 44 can move toward the first panel 41 to cut the paper tape 210. It can be understood that after the paper tape 210 is transferred from the paper tape transfer module 30 to the first panel 41, the first connecting rod 43 is rotated around the connecting bracket 42 to drive the shearing assembly 44 to move toward the direction close to the first panel 41, and the shearing assembly 44 cuts the paper tape 210 on the first panel 41 to form a paper sheet 220.

[0060] Furthermore, the first connecting rod 43 is connected to a push rod 45 at one end away from the connecting bracket 42, and is connected to the cam of the paper cup forming machine through the push rod 45. As the cam of the paper cup forming machine rotates, the push rod 45 is lifted and lowered and drives the first connecting rod 43 to rotate around the connecting bracket 42, thereby driving the shearing assembly 44 to move toward the first panel 41 to cut the paper tape 210, or to move away from the first panel 41 to separate from the paper tape 210, so as to facilitate the next shearing. Optionally, the shearing assembly 44 is fixedly connected to the middle of the first connecting rod 43.

[0061] The shearing assembly 44 includes an upper mold frame 441, a paper pressing plate 442, a pin 443, an elastic member 445, a first blade 446 and a second blade 447. The upper mold frame 441 is fixedly connected to the first connecting rod 43 and is movably connected to the paper pressing plate 442 through the pin 443. The two ends of the elastic member 445 elastically act on the upper mold frame 441 and the paper pressing plate 442 respectively. The first blade 446 and the second blade 447 are arranged opposite to each other, and the first blade 446 is installed on the upper mold frame 441, and the second blade 447 is installed on the first panel 41. It can be understood that as the shearing assembly 44 moves toward the first panel 41, the paper pressing plate 442 first cooperates with the first panel 41 to press the paper tape 210, and as the top rod 45 further rotates, the elastic member 445 is compressed, and the upper mold frame 441 drives the first blade 446 to move further downward along the pin 443 and cooperate with the second blade 447 to cut the paper tape 210.

[0062] Optionally, the elastic member 445 is configured as a spring, and the spring is sleeved on the outer periphery of the pin 443. The upper mold frame 441 is provided with a guide column 441a, and the first panel 41 is provided with a matching sleeve 411 corresponding to the guide column 441a. The guide column 441a is movably matched along the matching sleeve 411 in the height direction to guide the upper mold frame 441 to be pressed down more steadily.

[0063] Furthermore, the paper die-cutting feeding device 100 also includes a waste trough 70 and a waste box 80. The waste box 80 is installed on the frame 10 and is located in the space surrounded by two support plates 60. One end of the waste trough 70 is fixed to the first panel 41, and the other end extends to the top of the waste box 80. The shearing assembly 44 cooperates with the first panel 41 to cut the paper tape 210, and the paper scraps generated slide toward the waste box 80 through the waste trough 70.

[0064] Please refer to Figures 9 to Fig.11 The paper sheet transmission module 50 includes a mounting plate 52, a clamping assembly 53 and a transmission assembly 54. The clamping assembly 53 is connected to one end of the mounting plate 52 close to the paper tape die-cutting module 40 and is used to clamp the paper sheet 220. The transmission assembly 54 is connected to the mounting plate 52 and is used to drive the mounting plate 52 to reciprocate along the feeding direction a.

[0065] Furthermore, the paper sheet transmission module 50 also includes a second panel 51, which is fixed between the two support plates 60, and has a first station 511 and a second station 512 on the second panel 51. The paper cup forming machine has a leaf holding station 300, and a first paper pushing block 521 and a second paper pushing block 522 arranged at intervals along the feeding direction a are provided on the mounting plate 52; as the mounting plate 52 reciprocates along the feeding direction a, the paper sheet 220 is clamped to the first station 511 by the clamping assembly 53, and is first pushed to the second station 512 by the first paper pushing block 521 and the second paper pushing block 522, and then pushed to the leaf holding station 300.

One end of the second connecting rod 541 is connected to the mounting plate 52, and the other end is rotatably connected to the crank 542. The crank 542 is used to connect to the rotating power mechanism of the paper cup forming machine. It can be understood that the rotating power mechanism of the paper cup forming machine drives the crank 542 to rotate, and through the second connecting rod 541, the guide rail 543 and the slider 544 structure, the mounting plate 52 reciprocates along the feeding direction a.

[0069] The clamping assembly 53 includes a driving member 531, a first clamping block 532 and a second clamping block 533. The driving member 531 is connected to the first clamping block 532 and is used to drive the first clamping block 532 to move toward or away from the second clamping block 533 to clamp or loosen the paper sheet 220. The driving member 531 can be driven by a cylinder. Specifically, the paper sheet transport module 50 also includes a mounting frame 55, which is fixedly connected to one end of the mounting plate 52 close to the paper tape die-cutting module 40, and the clamping assembly 53 is installed on the mounting frame 55.
