[0002] In the production and processing of 3D printing filaments, winding is one of the key processes. It involves winding the continuously extruded or stretched 3D printing filaments onto a paper tube to form a rolled product that is easy to store, transport, and use.

[0003] Currently, 3D printing filament winding on the market is generally done manually by winding the 3D printing filament onto a paper tube. Some 3D printing filament winding setups also require manual intervention in paper tube feeding, positioning, unloading after winding, and conveying. This is not only labor-intensive, but also prone to low winding accuracy and poor product consistency due to human error. Furthermore, production efficiency is limited by the speed of manual operation, and the labor cost is relatively high. Therefore, there is a need to develop a device that can completely replace manual operation of paper tube feeding, positioning, and unloading after winding. Summary of the Invention

[0060] The material feeding mechanism 2 is located on the top of the frame 1 and is used to place the paper tube 100 that needs to be wound into 3D printing filament.

[0061] The paper tube clamping mechanism 3 is located on the frame 1 on one side of the material tray feeding mechanism 2, and is used to clamp the paper tube 100 in the material tray feeding mechanism 2;

[0062] The positioning mechanism 4 is set on the frame 1, located on the lateral side of the paper tube clamping mechanism 3, for clamping and positioning the paper tube 100, which facilitates the subsequent rolling operations of the pressing mechanism 6, the pneumatic wire cutting mechanism 7 and the adhesive tape applicator 8.

[0063] The filament feeding mechanism 5 is mounted on the frame 1, adjacent to the pre-positioning mechanism 4, and is used to guide the 3D printing filament onto the paper tube 100;

[0064] The tape application mechanism 8 is mounted on the frame 1, above the pre-positioning mechanism 4, and is used to apply tape to the paper tube after it is rolled to form the desired product.

[0065] The pressing mechanism 6 is mounted on the frame 1 and is located adjacent to the tape applicator 8. It is used to roll and abut against the 3D printing filament as it is wound on the paper tube 100.

[0066] The pneumatic wire cutting mechanism 7 is mounted on the pre-positioning mechanism 4 and is located adjacent to the wire laying mechanism 5. It is used to cut the 3D printing wire.

[0067] The receiving mechanism 9 is mounted on the frame 1, located below the pre-positioning mechanism 4, and is used to receive the rolled paper tube 100 and convey it to the paper tube 100 conveying mechanism 10.

[0068] The paper tube conveying mechanism 10 is located on the discharge side of the receiving mechanism 9 and is used to convey the rolled paper tube 100 to the collection point.

[0069] According to the flow sequence of the paper tube 100, it passes through the material tray feeding mechanism 2, the paper tube clamping mechanism 3, the pre-positioning mechanism 4, the receiving mechanism 9 and the paper tube conveying mechanism 10 in sequence;

[0070] The 3D printing filament is wound onto the paper tube 100 and flows through the filament winding mechanism 5, the pressing mechanism 6, the pneumatic filament cutting mechanism 7, and the adhesive tape application mechanism 8 in sequence.

[0071] like Figures 3-4 As shown, the material feeding mechanism 2 includes a multi-station rotating plate 201 that can be rotatably mounted on the top of the frame 1. The top of the multi-station rotating plate 201 has four multi-station dividing plates 202 that extend outward in a ring with the center position as the common point. The four multi-station dividing plates 202 are arranged in a cross shape, dividing the top of the multi-station rotating plate 201 into four stations.

[0072] A paper tube adjustment assembly 203 is provided on the top edge of the multi-station rotating plate 201 perpendicular to the multi-station dividing plate 202. Inside the frame 1, a first mounting plate 205 is mounted on the bottom of the multi-station rotating plate 201 via four rectangular array first mounting columns 204. A first rotary motor 206 is mounted on the bottom of the first mounting plate 205. The shaft of the first rotary motor 206 is driven by a coupling to a first rotating rod 207, which is driven by the multi-station rotating plate 201. The first rotary motor 206 can drive the multi-station rotating plate 201 to rotate, thereby realizing the alternation of the four stations.

[0073] The paper tube adjustment assembly 203 includes an adjustment seat 2031 mounted on a multi-station rotating plate 201. A vertical adjustment rod 2032 is fastened inside the adjustment seat 2031. Adjustment blocks 2033 are fastened to the upper and lower ends of the vertical adjustment rod 2032, respectively. Horizontal adjustment rods 2034 are fastened to the two ends of the adjustment blocks 2033, respectively. A station adjustment plate 2035 is fixedly connected to one end of the horizontal adjustment rod 2034 perpendicular to the multi-station dividing plate 202. The multi-station dividing plate 202 cooperates with two adjacent station adjustment plates 2035. 035 forms a placement space for placing paper tubes 100. The paper tubes 100 are placed into the placement space (i.e., workstation) by stacking. The height position of the workstation adjustment plate 2035 on the vertical adjustment rod 2032 can be adjusted by the adjustment block 2033 to accommodate paper tubes 100 of different heights. The distance between the workstation adjustment plate 2035 and the multi-workstation dividing plate 202 can be adjusted by the horizontal adjustment rod 2034 to accommodate paper tubes 100 of different diameters, thereby realizing the placement of paper tubes 100 of different sizes.

[0074] Sensor support plates 208 are fixedly connected to two adjacent first mounting columns 204. First blocking sensors 209 are installed on the sensor support plates 208. First blocking plates 210 that cooperate with the signal sensing of the first blocking sensors 209 are fastened to the first rotating rod 207. The rotation cycle of the multi-station rotating plate 201 can be known by the cooperation of the signal sensing of the first blocking sensors 209 and the first blocking plates 210, so as to clearly understand the working status of the multi-station rotating plate 201.

[0075] like Figures 5-7As shown, the paper tube clamping mechanism 3 includes an X-axis linear module 301 disposed within the frame 1, and an X-axis slide block 302 slidably engaged with the X-axis linear module 301. One end of the X-axis slide block 302 can slide through one side of the frame 1 and is fixedly connected to a clamping rotary seat 303. A second rotary motor 304 is mounted on the X-axis slide block 302. The shaft of the second rotary motor 304 is driven by a coupling to a second rotating rod 305. The second rotating rod 305 can rotatably pass through the clamping rotary seat 303 and is fixedly connected to a rotating connecting plate 306. A clamping linear module 307 is disposed on one side of the rotating connecting plate 306, and a clamping slide block 308 slidably engaged with the clamping linear module 307. A clamping rotary cylinder 309 is disposed on one side of the clamping slide block 308. A clamping plate 310 is rotatably connected to one side of 9. A clamping cylinder 311 is installed on the clamping plate 310 for clamping the paper tube 100. The clamping cylinder 311 can move along the X-axis direction through the cooperation of the X-axis linear module 301 and the X-axis slide 302. The clamping cylinder 311 can rotate around the X-axis through the cooperation of the second rotary motor 304, the second rotating rod 305 and the rotary connecting plate 306. The clamping cylinder 311 can extend and retract through the cooperation of the clamping linear module 307 and the clamping slide 308. The clamping cylinder 311 can rotate vertically by clamping the rotary cylinder 309, thereby realizing the omnidirectional movement of the clamping cylinder 311, which facilitates the clamping cylinder 311 to clamp the paper tube 100 placed in the workstation.

[0076] The X-axis linear module 301 is provided with a second obstruction sensor 312 at both ends, and the X-axis slide block 302 is provided with a second obstruction plate 313 that cooperates with the signal sensing of the second obstruction sensor 312; the cooperation of the second obstruction sensor 312 and the second obstruction plate 313 can determine the working position of the clamping cylinder 311 and the paper tube.

[0077] A third obstruction sensor 314 is provided on the X-axis slide block 302 next to the clamping rotary block 303. A third obstruction plate 315 is provided on the second rotating rod 305 to cooperate with the signal sensing of the third obstruction sensor 314. The cooperation of the third obstruction sensor 314 and the third obstruction plate 315 can know the rotation stroke of the rotating connecting plate 306 and the clamping cylinder 311 around the X-axis.

[0078] like Figure 8As shown, the positioning mechanism 4 includes a first support base plate 401 mounted on the frame 1. Two active slide rails 402 and a transmission slide rail 405 are arranged in parallel on the first support base plate 401. Active slide blocks 403 are slidably fitted on the two active slide rails 402, and transmission slide blocks 406 are slidably fitted on the transmission slide rail 405. An active rack 404 is mounted on the side of the active slide block 403 facing the transmission slide block 406, and a transmission rack 407 is mounted on the side of the transmission slide rail 405 facing the active slide block 403. The active rack 404 is connected to the transmission rack 407 via a transmission gear 408. The transmission gear 408 is rotatably mounted on the first support base plate 401 and located between the active rack 404 and the transmission rack 407. When the active slide block 403 moves, the mutual meshing of the active rack 404, the transmission rack 407, and the transmission gear 408 will cause the transmission slide block 406 to move in the opposite direction to the active slide block 403.

[0079] A positioning drive block 409 is provided on the side of the active slide block 403 away from the transmission slide block 406. A drive mounting base 410 is also provided on the top of the first support base plate 401. A positioning cylinder 411 is mounted on the drive mounting base 410. The telescopic shaft of the positioning cylinder 411 is connected to the positioning drive block 409. The positioning cylinder 411 can position the drive block 409 to move, thereby driving the active slide block 403 to slide on the active guide rail.

[0080] Two positioning connecting blocks 412 are provided on the side of the transmission slide 406 away from the active slide 403. One end of two positioning connecting columns 413 is fastened to the two positioning connecting blocks 412. The other end of the two positioning connecting columns 413 is fixedly connected to a positioning connecting plate 414. One end of the positioning connecting plate 414 is provided with a rotatable first positioning disk 415.

[0081] The active slide 403 is also provided with a motor mounting base 416 and a motor rotating base 417. A third rotary motor 418 is mounted on the motor mounting base 416. The rotating shaft of the third rotary motor 418 is connected to a third rotating rod 419 through a coupling. One end of the third rotating rod 419 can rotatably pass through the motor rotating base 417 and is fixedly connected to a second positioning plate 420. The second positioning plate 420 is used to cooperate with the first positioning plate 415 to clamp and position the paper tube, and drive the paper tube to rotate and roll, which facilitates the subsequent rolling operations of the pressing belt mechanism 6, the pneumatic wire cutting mechanism 7 and the adhesive tape applicator 8.

[0082] The positioning cylinder 411 drives the positioning drive block 409 and the active slide 403 to move back and forth along the X-axis. The active slide 403, through the transmission action of the active rack 404, the transmission gear 408 and the transmission rack 407, drives the transmission slide 406 to move in the opposite direction to the active slide 403. This allows the transmission slide 406 to drive the first positioning disk 415 and the active slide 403 to drive the second positioning disk 420 to move closer together to clamp the paper tube 100. At the same time, the third rotary motor 418 drives the third rotating rod 419 and the second positioning disk 420 to rotate. Since the first positioning disk 415 is rotatably connected to the positioning connecting plate 414, it drives the clamped paper tube 100 to rotate, so as to facilitate the subsequent winding of 3D printing filament.

[0083] The first positioning plate 415 and the second positioning plate 420 have a first positioning post 4151 and a second positioning post 4201 on the side close to each other. The first positioning post 4151 and the second positioning post 4201 can be inserted into the core of the paper tube 100 to achieve positioning, which can better position the paper tube 100 and prevent the paper tube 100 from falling due to unstable clamping.

[0084] After the paper tube clamping mechanism 3 clamps the paper tube, the paper tube 100 is moved between the first positioning plate 415 and the second positioning plate 420 by the cooperation of its X-axis linear module 301 and X-axis slide 302, the second rotary motor 304, the second rotating rod 305 and the rotating connecting plate 306, the clamping linear module 307 and the clamping slide 308, the clamping rotary cylinder 309 and the clamping cylinder 311, and the hollow center of the paper tube is aligned with the first positioning post 4151 and the second positioning post 4201. Then, the positioning cylinder 411 drives the first positioning plate 415 and the second positioning plate 420 to clamp and position the paper tube.

[0085] like Figures 9-12As shown, the cable routing mechanism 5 includes a second support base plate 501 mounted on the frame 1. Two X-axis vertical support plates 502 are vertically arranged at both ends of the top of the second support base plate 501. Three X-axis guide posts 503 are slidably arranged between the two X-axis vertical support plates 502. A common X-axis drive plate 504 is fastened onto the three X-axis guide posts 503. An X-axis lead screw 505 is rotatably connected between the two X-axis vertical support plates 502. The X-axis drive plate 504 is threaded onto the X-axis lead screw 505. One side of one X-axis vertical support plate 502 is open to… A second mounting plate 507 is mounted on the second mounting post 506 through the four rectangular arrays. An X-axis rotary motor 508 is mounted on one side of the second mounting plate 507. The rotating shaft of the X-axis rotary motor 508 is connected to the X-axis lead screw 505 through a coupling. The X-axis rotary motor 508 drives the X-axis lead screw 505 to rotate. The rotation of the X-axis lead screw 505 drives the X-axis drive plate 504 and the X-axis guide post 503 to move back and forth along the X-axis, thereby driving the 3D printing filament to move repeatedly along the X-axis on the paper tube, so that the 3D printing filament can be wound onto the paper tube 100 in an orderly manner.

[0086] Three X-axis guide posts 503 can slide through another X-axis vertical support plate 502, and each is fixedly connected to a Z-axis support plate 509. Two Z-axis rotary seats 510 are provided at the upper and lower ends of one side of the Z-axis support plate 509. Two Z-axis guide posts 511 are spaced apart between the two Z-axis rotary seats 510. A Z-axis drive plate 512 is slidably sleeved on the two Z-axis guide posts 511. A Z-axis lead screw 513 is rotatably connected between the two Z-axis rotary seats 510. The Z-axis drive plate 512 is threaded onto the Z-axis lead screw 513. The bottom of the Z-axis support plate 509... A Z-axis rotary motor 515 is mounted on one side of the part via a Z-axis mounting plate 514. The rotating shaft of the Z-axis rotary motor 515 is connected to a Z-axis lead screw 513 via a coupling. The Z-axis rotary motor 515 drives the Z-axis lead screw 513 to rotate. The rotation of the Z-axis lead screw 513 drives the Z-axis drive plate 512 to move up and down along the Z-axis guide post, that is, to move up and down along the Z-axis direction. This drives the 3D printing filament to move gradually upward along the Z-axis direction on the paper tube, which can make the 3D printing filament be wound on the paper tube in an orderly manner and avoid the 3D printing filament from crossing and tangling.

[0087] The top of the Z-axis drive plate 512 is provided with a Y-axis mounting plate 516 and a Y-axis rotary seat 517. A Y-axis rotary motor 518 is mounted on one side of the Y-axis mounting plate 516. The rotating shaft of the Y-axis rotary motor 518 is connected to a Y-axis lead screw 519 through a coupling. The Y-axis lead screw 519 can rotate through the Y-axis rotary seat 517 and is threaded with a cable tray 520.

[0088] The bottom of the Z-axis drive plate 512 is provided with a Y-axis guide rail 521, and a Y-axis slide block 522 is slidably fitted on the Y-axis guide rail 521. The Y-axis slide block 522 is fixedly connected to the cable tray 520. The Y-axis rotary motor 518 drives the Y-axis lead screw 519 to rotate. The rotation of the Y-axis lead screw 519 drives the cable tray 520 and the Y-axis slide block 522 to move left and right along the Y-axis guide rail 521, that is, to move left and right along the Y-axis direction, thereby driving the 3D printing filament to move in the Y-axis direction, so that the pneumatic filament cutting mechanism 7 can cut and finish the 3D printing filament after the winding is completed.

[0089] The top of the ribbon cable board 520 has a groove 5201, and the cable outlet assembly 523 is rotatably connected in the groove 5201 via a rotating pin. A ribbon cable rod 524 is provided on one side of the ribbon cable board 520. The ribbon cable rod 524 is provided with a first fastening block 525, a second fastening block 526, a third fastening block 527 and a fourth fastening block 528 in sequence from the inlet end to the outlet end of the plastic wire.

[0090] Among them, a first support rod 5251 is fastened to the first fastening block 525. The first support rod 5251 is provided with a first guide rod 5252 and a first limiting rod 5253 from bottom to top. A first guide wheel 5254 that can rotate is sleeved on the first guide rod 5252. The first guide rod 5252 is located above the first guide wheel 5254.

[0091] A second support rod 5261 is fastened to the second fastening block 526. A rotatable guide wheel 5262 is provided on the second support rod 5261. A guide groove 52621 for the plastic wire to pass through is provided on the guide wheel 5262.

[0092] A third support rod 5271 is fastened to the third fastening block 527. An abutting connecting rod 5272 is provided on the third support rod 5271. An abutting connecting plate 5273 is sleeved on the abutting connecting rod 5272. An abutting rod 5274 is provided on one side of the abutting connecting plate 5273. A rotatable abutting wheel 5275 is sleeved on the abutting rod 5274. The 3D printing filament passes through the wire groove 52621 of the wire guide wheel 5262 and is rolled and abutted by the abutting wheel 5275, which can straighten the introduction of the 3D printing filament and avoid the 3D printing filament from becoming messy.

[0093] A fourth support rod 5281 is fastened to the fourth fastening block 528. The fourth support rod 5281 is provided with a fourth guide rod 5282 and a fourth limiting rod 5283 from bottom to top. A rotatable fourth guide wheel 5284 is sleeved on the fourth guide rod 5282. The fourth guide rod 5282 is located above the fourth guide wheel 5284.

[0094] Both the first guide wheel 5254 and the fourth guide wheel 5284 are V-shaped, which can effectively limit and guide the 3D printing filament. The first limiting rod 5253 and the fourth limiting rod 5283 respectively limit the 3D printing filament, preventing it from running out.

[0095] like Figure 12 As shown, the cable exit assembly 523 includes a lower cable exit plate 5231 rotatably connected by a rotating pin. An upper cable exit plate 5232 is mounted on the top of the lower cable exit plate 5231. A cable exit tube 5233 is tightly secured between the lower cable exit plate 5231 and the upper cable exit plate 5232. The cable exit tube 5233 is used to pass through the 3D printing filament. A wire pressing hole 5234 is also provided on the lower cable exit plate 5231. Adjacent to the wire pressing hole 5234, there is also a... A pressure plate 5235 is provided, and an abutment cylinder 5236 is installed on one side of the pressure plate 5235. The telescopic shaft of the abutment cylinder 5236 passes through the pressure hole 5234 and is used to press the 3D printing filament. The filament outlet tube 5233 is used to guide the 3D printing filament to the positioned paper tube. By driving the telescopic shaft of the abutment cylinder 5236 to press the 3D printing filament passing through the pressure hole 5234, the introduction of the 3D printing filament can be stopped.

[0096] The 3D printing filament passes through the first guide wheel 5254, the guide wheel 5262 and the abutment wheel 5275, and the fourth guide wheel 5284 in sequence, and finally exits from the outlet tube 5233 and is introduced into the paper tube 100.

[0097] Two X-axis connecting rods are fixedly connected between the two X-axis vertical support plates 502. One of the X-axis connecting rods is equipped with three fourth obstruction sensors 529. The X-axis drive plate 504 is equipped with a fourth obstruction plate 530 that cooperates with the signal sensing of the fourth obstruction sensors 529. Through the signal sensing cooperation of the fourth obstruction sensors 529 and the fourth obstruction plate 530, the reciprocating travel of the 3D printing filament along the X-axis can be known, thereby determining the number of turns of the paper tube 100. The number of turns of the paper tube 100 can be set through the control panel 14.

[0098] Two fifth obstruction sensors 531 are provided at the upper and lower ends of one side of the Z-axis support plate 509. A fifth obstruction plate 532 is provided on the Z-axis drive plate 512 to cooperate with the signal sensing of the fifth obstruction sensors 531. Through the signal sensing cooperation of the fifth obstruction sensors 531 and the fifth obstruction plate 532, the movement of the 3D printing filament along the Y-axis can be known, thereby determining the number of layers wound into the paper tube. The number of layers wound into the paper tube can be set through the control panel 14.

[0099] like Figure 13As shown, the pressing mechanism 6 includes a pressing mounting plate 601 disposed on one side of the frame 1. A pressing rod 603 is fastened to one side of the pressing mounting plate 601 via a fastening seat 602. A pressing plate 604 is fixedly connected to one side of the pressing rod 603. Two pressing guide rods 605 are slidably fitted at both ends of the pressing plate 604. A pressing connecting plate 606 is fixedly connected to one end of the two pressing guide rods 605. A pressing block 608 is fixedly connected to one end of the pressing connecting plate 606 via two pressing support rods 607. A pressing wheel 609 is rotatably connected to the pressing block 608 via a rotating pin. The pressing wheel 609 is used to roll and abut against the 3D printing filament on the paper tube 100 for winding operations.

[0100] A pressure belt drive plate 610 is also fastened to the two pressure belt guide rods 605 between the pressure belt plate 604 and the pressure belt connecting plate 606. A pressure belt cylinder 611 is provided at one end of the pressure belt plate 604 relative to the pressure belt wheel 609. The telescopic shaft of the pressure belt cylinder 611 is fixedly connected to the pressure belt drive plate 610. The pressure belt drive plate 610 is moved towards the paper tube by the telescopic shaft driven by the pressure belt cylinder 611. The pressure belt drive plate 610 drives the two pressure belt guide rods 605 to slide on the pressure belt plate 604. Thus, the two pressure belt guide rods 605 drive the two pressure belt support rods 607, the pressure belt block 608 and the pressure belt wheel 609 to move towards the paper tube 100 and roll and abut against the introduced 3D printing filament.

[0101] When the pressure roller 609 contacts the 3D printing filament, it drives the first positioning plate 415 to rotate, which in turn drives the clamped paper tube 100 to rotate via the second positioning plate 420. This allows the 3D printing filament from the outlet tube 5233 to be continuously introduced, while simultaneously driving the 3D printing filament to move along the X and Y axes. This ensures that the 3D printing filament is orderly wound onto the paper tube 100, resulting in better winding efficiency and quality compared to manual winding.

[0102] like Figures 15-17 As shown, the tape application mechanism 8 includes two fixed seats 801 disposed on one side of the frame 1, and two fixed rods 802 are fastened to the two fixed seats 801.

[0103] One end of each of the two fixed rods 802 is fixedly connected to a first fixed plate 803. A tape adjusting cylinder 804 is provided on one side of the first fixed plate 803. The telescopic shaft of the tape adjusting cylinder 804 is fixedly connected to a first L-shaped connecting plate 805. A fixed frame 806 is fixedly connected to the bottom of the first L-shaped connecting plate 805. A tape plate 807 is fixedly connected to one end of the bottom of the fixed frame 806. Tape rotating rods 808 are rotatably connected to opposite ends of the tape plate 807. Tape reels 809 are respectively fitted onto the two tape rotating rods 808. The tape reels 809 are used to fit the tape 200.

[0104] A U-shaped support frame 810 is fixedly connected to the bottom of the fixed frame 806. A lower clamping plate 811 is fixedly connected to the bottom of the U-shaped support frame 810. Two limiting grooves 8111 for the tape 200 to pass through are spaced apart on the lower clamping plate 811. A clamping cylinder 812 is provided on one side of the U-shaped support frame 810 above the lower clamping plate 811. An upper clamping plate 813 is fixedly connected to the telescopic shaft of the clamping cylinder 812. The upper clamping plate 813 and the lower clamping plate 812 are connected together. The holding plate 811 is used to clamp the passing tape 200. A guide frame 814 is provided on the other side of the U-shaped support frame 810. Two guide wheels 815 are provided at opposite ends of the guide frame 814 corresponding to the two tape reels 809. The guide wheels 815 can guide and limit the introduction of the tape 200. The upper clamping plate 813 is driven by the clamping cylinder 812 to clamp the lower clamping plate 811, thereby clamping and fixing the passing tape 200.

[0105] In addition, the guide frame 814 has tape warning units 8141 corresponding to the guide wheels 815 installed at both ends of the guide frame 814 via bending plates. These units are used to monitor in real time whether there is tape 200 on the guide wheels 815, thereby monitoring in real time whether the tape 200 on the tape reel 809 is used up. This allows the operator to replace the tape 200 on the tape reel 809 in a timely manner, ensuring the continuity of the rolling operation.

[0106] The two limiting grooves 8111 correspond to the two guide wheels 815, and the two guide wheels 815 correspond to the two tape reels 809. The tape adjusting cylinder 804 drives the first L-shaped connecting plate 805 to move the fixing frame 806 left and right along the Y-axis, thereby causing the two tape reels 809 to move left and right alternately, and also causing the two limiting grooves 8111 to move left and right alternately, thus realizing the alternating use of tape 200 on the two tape reels 809, further ensuring the continuous and uninterrupted operation of the rolling.

[0107] The tape warning unit 8141 monitors in real time whether the tape on the tape reel 809 is used up. When the tape on one tape reel 809 is used up, the tape warning unit 8141 detects that no tape is being turned out of the guide wheel 815, and then transmits a signal to the control panel 14 to drive the tape adjusting cylinder 804 to move the other tape reel 809 and the corresponding guide wheel 815 and limit groove 8111 to the working area, so that the tape application work can continue. At the same time, it reminds the operator to replace the tape 200 on the used tape reel 809.

[0108] The other end of the two fixed rods 802 is fixedly connected to a second fixed plate 816. The bottom of the second fixed plate 816 is fastened to a tension rod 817. One end of the tension rod 817 is fixedly connected to a first telescopic cylinder 818. The telescopic shaft of the first telescopic cylinder 818 is fixedly connected to a second L-shaped connecting plate 819. One side of the second L-shaped connecting plate 819 is fixedly connected to a second telescopic cylinder 820. The telescopic shaft of the second telescopic cylinder 820 is fixedly connected to a tension drive plate 821. One side of the tension drive plate 821 is provided with a tension clamping cylinder 822. The tension clamping cylinder 822 has a gripper on the side of the downward clamping plate 811 that can clamp the tape.

[0109] The extension and retraction of the first telescopic cylinder 818 and the second telescopic cylinder 820 can drive the two ends of the tensioning cylinder to move. When the clamping cylinder has clamped the tape 200 and it is necessary to tighten the tape 200, the first telescopic cylinder 818 drives the second L-shaped connecting plate 819 to extend and retract, thereby realizing the clamping cylinder's tightening effect on the tape 200, so as to facilitate the cutting of the tape 200.

[0110] When the clamping cylinder is not clamping the tape 200, the first telescopic cylinder 818 drives the clamping cylinder to move a certain distance, and then the second telescopic cylinder 820 drives the clamping cylinder's jaws to move to the tape 200 that is exposed between the upper clamping plate 813 and the lower clamping plate 811. The clamping cylinder drives its jaws to clamp the tape, and then the first telescopic cylinder 818 and the second telescopic cylinder 820 drive the clamping cylinder to return along the original path, simultaneously clamping and tightening the tape 200.

[0111] Two fixed rods 802 are fixedly connected to adhesive support plates 823 on the side adjacent to the first fixed plate 803. Two adhesive rotating plates 824 are fixedly connected to the upper and lower ends of the adhesive support plates 823. Two adhesive guide posts 825 are provided between the two adhesive rotating plates 824. An adhesive driving plate 826 is slidably sleeved between the two adhesive guide posts 825. Two adhesive rods 827 are fixedly connected to the bottom of the adhesive driving plate 826. An adhesive tape adsorption plate 828 is fixedly connected to the bottom of the two adhesive rods 827. The adhesive tape adsorption plate 828 is located above the pre-positioning mechanism 4 and is used to drive the adhesive tape to be attached to the rolled paper tube, so that the paper tube 100 becomes the product to be processed.

[0112] An adhesive application screw 829 is rotatably connected between the two adhesive application rotating plates 824. An adhesive application drive plate 826 is threaded onto the adhesive application screw 829. The upper adhesive application rotating plate 824 is equipped with a fourth rotary motor 831 via a third mounting post 830. The shaft of the fourth rotary motor 831 is connected to the adhesive application screw 829 via a coupling. The fourth rotary motor 831 drives the adhesive application screw 829 to rotate. The rotation of the adhesive application screw 829 causes the adhesive application drive plate 826 to move up and down along the two adhesive application guide posts 825, thereby causing the two adhesive application rods 827 and the tape adsorption plate 828 to move up and down, so that the tape 200 is attached to the rolled paper tube 100.

[0113] like Figure 16 As shown, the bottom of the tape adsorption plate 828 has a rectangular array of air holes 8281. The top of the tape adsorption plate 828 is provided with an air pipe 8282 that connects to the air holes 8281. The air pipe 8282 generates negative pressure on the air holes 8281, thereby enabling the air holes 8281 to adsorb the back of the tape 200, preventing the tape 200 from detaching from the tape adsorption plate 828 when the tape adsorption plate 828 moves the tape 200 downward.

[0114] Two fixed rods 802 are fastened with vertical cutting plates 832 adjacent to the two fixed seats 801. The bottom of the vertical cutting plates 832 is fixedly connected to horizontal cutting plates 834 via four cutting plate connecting posts 833. Cutting cylinders 835 are respectively installed at both ends of the horizontal cutting plates 834. L-shaped drive plates 836 are respectively fixedly connected to the telescopic shafts of the two cutting cylinders 835. Scissor mounting brackets 838 and cutting plate mounting plates 839 are respectively fixedly connected to one side of the two L-shaped drive plates 836 via cutting plate connecting plates 837. Scissors facing the tape 200 are mounted on the scissor mounting brackets 838. The scissors are mounted on the scissor mounting brackets 838 by tightening external fastener bolts. The cutting plate mounting plate 839 is located on the scissor mounting brackets. Above 838, a tape-cutting drive cylinder (not shown in the figure) is installed on the top of the tape-cutting mounting plate 839 to drive the tape-cutting scissors. The telescopic shaft of the tape-cutting drive cylinder is connected to the tape-cutting drive rod 840, and the bottom of the tape-cutting drive rod 840 can abut against the scissors. The tape-cutting cylinder 835 drives the L-shaped drive plate 836 to move towards the tape 200. The L-shaped drive plate 836 drives the tape-cutting connecting plate 837, the scissors mounting bracket 838, and the scissors mounted on the tape-cutting mounting plate 839 to move towards the tape 200, so that the blades of the scissors move to the upper and lower ends of the tape 200. Then, the tape-cutting drive cylinder drives its telescopic rod to drive the tape-cutting drive rod 840 to abut against the top of the scissors, thereby realizing that the scissors cut the taut tape 200.

[0115] Two sixth blocking sensors 841 are provided at the top and bottom of one side of the adhesive support plate 823, and a sixth blocking plate 842 is provided on one side of the adhesive drive plate 826 to cooperate with the signal sensing of the sixth blocking sensors 841. Through the signal sensing cooperation of the sixth blocking sensors 841 and the sixth blocking plate 842, the travel of the tape adsorption plate 828 moving up and down can be known, and it can be clear whether the tape adsorption plate 828 drives the tape 200 to apply adhesive to the rolled paper tube 100.

[0116] like Figure 14 As shown, the pneumatic wire cutting mechanism 7 includes a support base 701 mounted on the first support base plate 401 of the pre-positioning mechanism 4. A first connecting column 702 is fastened to the support base 701. A second connecting column 704 is fastened to the first connecting column 702 via a first connecting block 703. A third connecting column 706 is fastened to the second connecting column 704 via a second connecting block 705. A wire cutting plate 707 is fixedly connected to the top of the third connecting column 706. Two wire cutting plates are vertically slidably fitted on the wire cutting plate 707. Guide pillars 708, one end of the two wire-cutting guide pillars 708 is fixedly connected to a wire-cutting drive plate 709, the wire-cutting drive plate 709 is provided with a scissor cylinder 710 for cutting 3D printing filament on the side opposite to the wire-cutting plate 707, the scissor cylinder 710 is provided with scissors facing the 3D printing filament for cutting 3D printing filament, a wire-cutting drive cylinder 711 is installed on one side of the wire-cutting plate 707, the telescopic shaft of the wire-cutting drive cylinder 711 can move through the wire-cutting plate 707 and is fixedly connected to the wire-cutting drive plate 709;

[0117] The filament cutting drive cylinder 711 drives its telescopic rod to move the filament cutting drive plate 709 along the X-axis. The filament cutting drive plate 709 then drives the scissor cylinder 710 to move toward the 3D printing filament, so that the scissor blades on the scissor cylinder 710 are located at the upper and lower ends of the 3D printing filament. Subsequently, the scissor cylinder 710 drives the scissors to cut the 3D printing filament.

[0118] like Figures 18-19As shown, the receiving mechanism 9 includes a support side plate 901 mounted on the frame 1. Two receiving guide rails 902 are spaced apart on one side of the support side plate 901, and two receiving rotating seats 903 are perpendicularly arranged to the two receiving guide rails 902. A receiving screw 904 is rotatably connected between the two receiving rotating seats 903. Two receiving slides 905 are slidably fitted onto the two receiving guide rails 902. A receiving bracket 906 is mounted on one side of each receiving slide 905. The receiving bracket 906 is threaded onto the receiving screw 904 via a connecting seat, providing support. A receiving mounting plate 907 is also provided on one side of the side plate 901. A receiving motor 908 is installed on the receiving mounting plate 907. The rotating shaft of the receiving motor 908 is connected to the receiving screw 904 through a coupling. The receiving motor 908 drives the receiving screw 904 to rotate. The rotation of the receiving screw 904 drives the receiving bracket 906 to move up and down on the two receiving guide rails 902 through the two receiving slides 905, thereby driving the V-shaped receiving frame 912 to move up and down, which can carry out receiving and transporting operations on the rolled paper tube 100.

[0119] A movable rod 909 is fastened to the receiving bracket 906. A movable slot 11 is provided on the frame 1 for the movable rod 909 to move up and down. A receiving rotary cylinder 910 is fixedly connected to one end of the movable rod 909. An inclined hinge plate 911 is rotatably connected to the top of the receiving rotary cylinder 910. One end of a V-shaped receiving bracket 912 is hinged to the top of the inclined hinge plate 911, and one end of a receiving cylinder 913 is hinged to the bottom of the inclined hinge plate 911. The receiving cylinder 913... The telescopic shaft is hinged to the other end of the V-shaped receiving frame 912. Two receiving support rods are also provided at intervals between the bottom of the V-shaped receiving frame 912 and the inclined hinge plate 911. The receiving support rods can support the V-shaped receiving frame 912, avoid excessive load on the receiving cylinder 913, and ensure the service life of the receiving cylinder 913. The V-shaped receiving frame 912 is located below the first positioning plate 415 and the second positioning plate 420 and is used to receive the rolled paper tube 100.

[0120] When the rolled paper tube 100 needs to be received, the receiving rotary cylinder 910 drives the V-shaped receiving frame 912 to rotate 90°, so that the two ends of the V-shaped receiving frame 912 can smoothly abut the two ends of the paper tube 100, so that the paper tube 100 is abutted and will not roll. The receiving motor 908 drives the V-shaped receiving frame 912 to move upward, so that the V-shaped receiving frame 912 receives the paper tube 100. After receiving, the receiving motor 908 drives the V-shaped receiving frame 912 to move downward. Then, the receiving motor 908 rotates to drive the V-shaped receiving frame 912 to rotate back 90°. Immediately afterwards, the receiving cylinder 913 drives its telescopic shaft to lift one end of the V-shaped receiving frame 912. Due to the hinge, the other end of the V-shaped receiving frame 912 forms a lever principle, so that the V-shaped receiving frame 912 tilts towards the paper tube conveying mechanism 10, so that the paper tube 100 flips and falls into the paper tube conveying mechanism 10 for conveying.

[0121] Two seventh blocking sensors 914 are also provided at the upper and lower ends of one side of the support side plate 901, and a seventh blocking plate 915 is provided on one side of the receiving bracket 906 to cooperate with the signal sensing of the seventh blocking sensors 914; through the signal sensing cooperation of the seventh blocking sensors 914 and the seventh blocking plate 915, the up and down stroke of the V-shaped receiving bracket 912 can be known, so as to clearly know the number of times the V-shaped receiving bracket 912 receives the paper tube 100.

[0122] like Figure 20 As shown, the paper tube conveying mechanism 10 includes a second frame 101 disposed on the adjacent side of the frame 1 and the V-shaped receiving frame 912. A conveying motor 103 is mounted on one side of the second frame 101 via an L-shaped mounting plate 102. The shaft of the conveying motor 103 rotatably passes through the L-shaped mounting plate 102 and is fitted with a first gear 104. The first gear 104 is connected to a second gear 106 via a belt 105. A rotatable first conveying wheel 108 is disposed at one top end of the second frame 101, and a rotatable second conveying wheel 107 is disposed at the other top end of the second frame 101. A second gear 106 is fitted on one side of the conveyor wheel 107. The first conveyor wheel 108 is connected to the second conveyor wheel 107 via a conveyor belt 109. The first gear 104 is driven to rotate by the conveyor motor 103. The first gear 104 drives the second gear 106 to rotate synchronously via the belt 105. The rotation of the second gear 106 drives the second conveyor wheel 107 to rotate synchronously. The second conveyor wheel 107 drives the first conveyor wheel 108 to rotate synchronously via the conveyor belt 109, thereby realizing the conveying of the paper tubes falling onto the conveyor belt 109. The conveyor belt 109 transports the paper tubes 100 to the paper tube collection point.

[0123] To facilitate the movement of rack 1 and rack 101 and to adapt to different terrains, four height-adjustable support feet 12 are installed at the four corners of the bottom of rack 1 and rack 101. The support feet 12 can adapt rack 1 and rack 101 to different terrain environments and also provide support. Four support guide wheels 13 are also installed at the bottom of rack 1 next to the support feet 12 to facilitate the movement of the entire rack 1.

[0124] When the support foot pad 12 is raised, the support guide wheel 13 contacts the ground and moves; when the support foot pad 12 is lowered, the support guide wheel 13 is suspended in the air and the equipment is fixed.

[0125] Working principle: It is specifically divided into the following stages;

[0126] Paper tube feeding stage: First, the height of the station adjustment plate 2035 in the paper tube adjustment assembly 203 and the distance between it and the multi-station division plate 202 are adjusted manually in advance according to the diameter and width of the paper tube 100. Finally, the multi-station division plate 202 and the two adjacent station adjustment plates 2035 form a placement space that is suitable for the size of the paper tube. Then, the paper tube 100 is placed into each placement space in a stacked manner. Subsequently, the motors and cylinders corresponding to each mechanism are driven by the control panel 14.

[0127] Paper tube transfer stage: The gripping rotary cylinder 309 drives the gripping cylinder 311 to face the paper tube, the X-axis linear module 301 starts, and drives the X-axis slide 302 to slide along the X-axis linear module 301 towards the material feeding mechanism 2; when the second baffle plate 313 on the X-axis slide 302 moves to align with the second baffle sensor 312 at one end of the X-axis linear module 301, the X-axis slide 302 stops. At this time, the gripping cylinder 311 starts its gripper to close and clamp the bottom paper tube. Then, the X-axis linear module 301 drives the X-axis slide 302 back along the original path to remove the paper tube from the stack and adjust it to a horizontal position.

[0128] Next, the paper tube 100 is transferred to the pre-positioning mechanism 4. The gripping rotary cylinder 309 drives the gripping cylinder 311 to reset, the second rotary motor 304 starts, and drives the rotating connecting plate 306 to rotate through the second rotating rod 305. The angle of the gripping cylinder 311 is adjusted to align between the first positioning plate 415 and the second positioning plate 420. Subsequently, the gripping linear module 307 drives the gripping slide 308 to move the gripping cylinder 311 towards the first positioning plate 415 and the second positioning plate 420, so that the axis of the paper tube is coaxial with the axis of the first positioning plate 415 and the second positioning plate 420, thus completing the transfer and alignment of the paper tube 100.

[0129] Paper tube positioning stage: The positioning cylinder 411 is activated, and its telescopic shaft pushes the active slide 403 to slide forward along the two active slide rails 402; the active rack 404 on the active slide 403 moves synchronously, and through meshing with the transmission gear 408, it drives the transmission rack 407 (fixed to the transmission slide 406) to move in the opposite direction, thereby causing the transmission slide 406 to slide in the opposite direction along the transmission slide rail 405, so as to realize the synchronous approach of the first positioning disk 415 and the second positioning disk 420.

[0130] When the first positioning post 4151 of the first positioning disk 415 and the second positioning post 4201 of the second positioning disk 420 are respectively inserted into the hollow cores at both ends of the paper tube 100, the positioning cylinder 411 stops extending and retracting; at this time, the paper tube is clamped by the two positioning disks, and the cooperation between the first positioning post 4151, the second positioning post 4201 and the core of the paper tube 100 ensures the coaxiality of the paper tube, providing stable support for subsequent rotation and winding; at the same time, the third rotary motor 418 is in standby mode, and will be started after the 3D printing filament is guided into place to drive the paper tube 100 to rotate.

[0131] During the wire winding stage: The X-axis rotary motor 508 starts, driving the X-axis lead screw 505 to rotate, causing the X-axis drive plate 504 to slide along the X-axis guide post 503, adjusting the position of the Z-axis support plate 509 and the subsequent wire exit assembly 523 in the width direction of the paper tube, so that the wire exit tube 5233 is aligned with one end of the paper tube; the Z-axis rotary motor 515 starts, driving the Z-axis lead screw 513 to rotate, causing the Z-axis drive plate 512 to slide up and down along the Z-axis guide post, adjusting the height of the wire exit assembly 523, so that the wire exit tube 5233 is in contact with the surface of the paper tube; the Y-axis rotary motor 518 starts, driving the Y-axis lead screw 519 to rotate, causing the wire guide plate 520 to be finely adjusted along the Y-axis guide rail 521. The 3D printing filament passes sequentially through the first guide wheel 5254 (limited by the first limiting rod 5253) on the filament guide rod 524, the wire groove 52621 of the wire guide wheel 5262 (to prevent deviation), the abutment wheel 5275 (to tension the filament), and the fourth guide wheel 5284 (limited by the fourth limiting rod 5283) on the filament guide rod 524, and finally exits from the filament outlet tube 5233 of the filament outlet assembly 523 and adheres to the surface of the paper tube. When the 3D printing filament needs to stop working, the abutment cylinder 5236 is activated, driving its telescopic shaft to pass through the wire pressing hole 5234 of the lower filament outlet plate 5231, pressing the filament tightly at the end of the filament outlet tube 5233, which can pause the filament introduction work at any time.

[0132] After the paper tube is wound, the filament cutting drive cylinder 711 is activated. Its telescopic shaft pushes the filament cutting drive plate 709 to move along the filament cutting guide post 708 towards the filament (3D printing filament), causing the scissor cylinder 710 to approach the filament. When the scissors are aligned with the filament, the scissor blades of the scissor cylinder 710 close, cutting the 3D printing filament. The filament cutting drive cylinder 711 then extends and retracts in the opposite direction, causing the scissor cylinder 710 to reset and wait for the next cycle.

[0133] During this period, the third rotary motor 418 drives the first positioning disk 415 to continue rotating, causing the end of the 3D printing filament to move to the side adjacent to the pressure roller 609;

[0134] Subsequently, the grippers of the tensioning and clamping cylinder 822 close, clamping the tape 200 drawn from the tape reel 809. Guided by the guide wheel 815, the tape 200 is pulled out by the grippers of the tensioning and clamping cylinder 822 through the limiting groove 8111 of the lower clamping plate 811. Simultaneously, the cooperation of the first telescopic cylinder 818 and the second telescopic cylinder 820 drives the tensioning drive plate 821 to move away from the tape reel 809, pulling the tape 200 out to a set length. The pressing and clamping cylinder 812 is activated, and the upper clamping plate 813 moves downward, cooperating with the lower clamping plate 811 to clamp the end of the remaining tape 200, preventing the tape 200 from loosening. The tape adsorption plate 828 is driven downward by the fourth rotary motor 831, and after moving to the upper surface of the tape 200, the tape adsorption plate 828... The tape 200 is adsorbed by the air tube 8282 connected to an external negative pressure device, which generates negative pressure at the air holes 8281 at the bottom of the tape adsorption plate 828. Subsequently, the tape cutting cylinder 835 is activated, pushing the L-shaped drive plate 836 to move the scissor mounting bracket 838 and the tape cutting mounting plate 839 closer to the tape 200. The telescopic shaft of the tape cutting drive cylinder pushes the tape cutting drive rod 840 downward, driving the scissors to cut the tape 200. The fourth rotary motor 831 continues to drive the tape adsorption plate 828 to move the tape downward until the tape 200 is attached to the rolled paper tube, thus completing the product after processing the paper tube and 3D printing filament. When the tape adsorption plate 828 moves the tape downward, the grippers of the tensioning clamping cylinder 822 will release their grip on the tape 200.

[0135] Finished product conveying stage:

[0136] The receiving rotary cylinder 910 drives the V-shaped receiving frame 912 to rotate 90°. Subsequently, the receiving motor 908 starts, driving the receiving screw 904 to rotate, which in turn drives the receiving bracket 906 to slide upward along the receiving guide rail 902. When the seventh baffle plate 915 on the receiving bracket 906 aligns with the seventh baffle sensor 914 on the support side plate 901, the receiving bracket 906 stops. At this time, the V-shaped receiving frame 912 is located below the paper tube 100. The positioning cylinder 411 of the positioning mechanism 4 extends and retracts in the opposite direction, and the active slide 403 and the transmission slide 406 move away synchronously. The first positioning... Positioning post 4151 and second positioning post 4201 are pulled out from the core of the paper tube. The paper tube falls into the V-shaped receiving frame 912 under the action of gravity, so that the paper tube 100 is abutted by the V-shaped receiving frame 912 and will not roll. Then, the receiving motor 908 drives the V-shaped receiving frame 912 to move downward. The receiving motor 908 rotates and drives the V-shaped receiving frame 912 to rotate back 90°. The receiving cylinder 913 is activated, and its telescopic shaft pushes the V-shaped receiving frame 912 to rotate around the hinge point, adjusting the posture of the finished paper tube. The paper tube is then aligned with the conveyor belt 109 of the paper tube conveying mechanism 10 and tilted down.

[0137] When the paper tube falls into the conveyor belt 109, the conveyor motor 103 starts, and its shaft drives the second conveyor wheel 107 to rotate through the first gear 104, belt 105 and second gear 106. The second conveyor wheel 107 drives the first conveyor wheel 108 to rotate synchronously through the conveyor belt 109, thereby realizing the conveying of the paper tube 100 that has fallen onto the conveyor belt 109. The conveyor belt 109 transports the paper tube to the set paper tube collection point, thereby completing the entire rolling process.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
