[0002] The existing cutting processes for tipping paper materials mainly include cutter cutting and laser cutting.

[0003] Cutter cutting is a processing method that uses a number of circular cutting edges arranged in an array on a cutter to cut tipping paper under high pressure, thereby obtaining a number of tipping papers with circular contours.

[0004] Laser cutting is a processing method that uses the high energy density characteristic of a laser to irradiate the surface of tipping paper, vaporize the irradiated area, and thus obtain the required shape contour.

Detailed Embodiment

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0033] like Figure 1-6 As shown, a sealing paper tube laser cutting device is provided as an embodiment of the present invention, that is, a process for cutting a plurality of circular holes on the tipping paper 12 (high-transparency paper). The device includes a conveying module 7 and a jig 6 for carrying the paper tube 11 and the tipping paper 12. The jig 6 is placed on the conveying module 7, and the conveying module 7 is used to drive the jig 6 to move linearly.

[0034] Among them, the conveying module 7 adopts a double-speed line, which refers to a special type of conveying system used to transport products or components on a production line. Its main feature is to accelerate (i.e., move products or components at a faster speed than other sections) within a specific section so as to complete certain operations more efficiently. No limitation or elaboration is made.

[0035] Also includes:

[0036] The fixture positioning module 4 is used to lift the fixture 6 on the conveying module 7 and position and fix it.

[0037] Among them, the fixture positioning module 4 includes a base plate 28, a lifting guide assembly is installed on the base plate 28, the output end of the lifting guide assembly is connected to the top plate 29, and the top plate 29 is fixed with a positioning pin 22 adapted to the positioning hole of the fixture 6 and a support column 21 for supporting the fixture 6, and the lifting guide assembly is used to drive the top plate 29 to rise and fall.

[0038] Preferably, the lifting guide assembly includes a lifting cylinder 18, a guide rod 19 and a linear bearing 20. A plurality of lifting cylinders 18 are fixed on the base plate 28. The output end of the lifting cylinder 18 is fixedly connected to the top plate 29. A plurality of linear bearings 20 are also fixed on the base plate 28. The linear bearing 20 is slidably connected with a guide rod 19. The other end of the guide rod 19 is fixedly connected to the top plate 29. In this way, the lifting cylinder 18 can stably drive the positioning pin 22 and the support column 21 on the top plate 29 to move up and down under the action of compressed air.

[0039] Preferably, a dust suction pipe 23 for dust suction is installed on the lower side of the bottom plate 28, which can ensure the cleanliness of the processing environment, thereby improving the quality of laser cutting.

[0040] The laser cutting module is installed on the lifting module 3, and the lifting module 3 is used to drive the laser cutting module to rise and fall; after the jig positioning module 4 positions the jig 6, the laser cutting module is used to emit a plurality of annular laser beams 13 to cut the tipping paper 12 on the jig 6.

[0041] The lifting module 3 may be a hand wheel and a screw rod combination structure, that is, the laser cutting module is threadedly connected to the screw rod, and the screw rod is driven to rotate by rotating the hand wheel to achieve the lifting action of the laser cutting module, which is not limited or elaborated.

[0042] The laser cutting module includes a galvanometer lens 1 and a laser 2, wherein the laser 2 is used to emit a laser beam 13, and the galvanometer lens 1 is used to guide the laser beam 13. After the jig positioning module 4 positions the jig 6, the laser 2 receives a positioning confirmation signal from the control system and emits a laser beam 13, which is guided by the galvanometer lens 1 to form an array of circular laser beams 13 (i.e., the beams are made to walk out of circular optical paths that match the paper tubes 11 on the jig 6), thereby cutting the tipping paper 12 on the outer periphery of the paper tubes 11 on the jig 6, so that the paper tubes 11 form a sealed paper tube 25.

[0043] The scrap collecting module 5 is used to remove the remaining scraps 26 of the tipping paper 12 cut on the fixture 6.

[0044] Among them, the scrap collection module 5 includes two linear guide rails 30, and a cylinder mounting plate 27 is installed on the two linear guide rails 30. A moving component for driving the cylinder mounting plate 27 to move is also installed on the linear guide rails 30. A lifting cylinder 15 is fixed on the cylinder mounting plate 27, and a clamping cylinder 14 for clamping the remaining scraps 26 of the kraft paper 12 is installed at the output end of the lifting cylinder 15. The extension and return of the lifting cylinder 15 can drive the clamping cylinder 14 to move up and down, and the opening and clamping of the clamping cylinder 14 can grasp and release the kraft paper 12.

[0045] Preferably, the moving component includes a servo motor 16, a synchronous belt 17 and a synchronous pulley 24. Two synchronous pulleys 24 are rotatably installed on the linear guide 30. A synchronous belt 17 is wound around the two synchronous pulleys 24. The synchronous belt 17 is also fixedly connected to the cylinder mounting plate 27. The linear guide 30 is also fixed with a servo motor 16 that is transmission-connected to one of the synchronous pulleys 24. When the servo motor 16 works, it drives the synchronous pulley 24 and the synchronous belt 17 to rotate, and the synchronous belt 17 can drive the cylinder mounting plate 27 to move on the linear guide 30.

[0046] In one embodiment, it further includes a stopper 8 and a check valve 9 for blocking and check-valving the fixture 6; a blanking rod 10 can also be provided to facilitate the collection and transfer of the scrap 26.

[0047] The working process of this sealing paper tube laser cutting equipment is as follows:

[0048] 1) The paper tube 11 on the fixture 6 flows into the laser cutting workstation through the conveying module 7;

[0049] 2) The fixture positioning module 4 works. The lifting cylinder 18 extends, and the positioning pin 22 is inserted into the positioning hole on the fixture 6 to position the fixture 6, and the support column 21 supports the fixture 6;

[0050] 3) The scrap collection module 5 works. The servo motor 16 operates to drive the lifting cylinder 15, and the jaw cylinder 14 moves to the designated position. The lifting cylinder 15 extends, and the jaw cylinder 14 clamps the scrap 26;

[0051] 4) The control system of the laser 2 receives the positioning confirmation signal, and the laser 2 emits a laser beam 13. The laser beam 13 is guided by the galvanometer scanner 1, so that the beam forms a circular light path, thereby achieving the effect of cutting the tipping paper 12;

[0052] 5) The lifting cylinder 18 of the fixture positioning module 4 returns, and the fixture 6 descends onto the conveying module 7 and flows out of the laser cutting workstation; at the same time, the lifting cylinder 15 of the scrap collection module 5 returns and descends, the servo motor 16 returns, the jaw cylinder 14 releases, and the scrap 26 falls into the collection box; the laser paper cutting and scrap collection work are completed.

[0053] In the above embodiment of the present invention, a sealing paper tube laser cutting equipment is provided. By adopting the conveying module 7 of the double-speed line body, the movement of products in a specific section can be accelerated, thereby improving production efficiency. In addition, the entire working process from feeding, positioning, cutting to scrap collection has achieved automated operation, greatly improving work efficiency. Specifically:

[0054] The fixture positioning module 4 can lift and fix the fixture 6, ensuring the position consistency during each processing; while the laser cutting module can achieve precise guidance through the galvanometer scanner 1, ensuring that the cutting path of the laser beam 13 is accurate, so that the cutting of each round hole meets the design requirements.

[0055] The handwheel and lead screw combination structure of the lifting module 3 and the servo motor drive system of the scrap collection module 5 provide good adjustment performance, and the height of the laser 2 or the collection position of the scrap 26 can be adjusted according to actual needs, enhancing the adaptability and operability of the equipment.

[0056] A dust suction pipe 23 is installed on the lower side of the bottom plate 28, which can timely remove the generated dust and other impurities during the processing. This not only helps to maintain the cleanliness of the workshop environment, but also is beneficial to improving the product quality and avoiding the influence of pollution on the laser cutting effect.
