Description

Technical Field

[0001] The present invention relates to the technical field of laser drilling, and particularly relates to a laser drilling machine for tipping paper processing. Background Art

[0002] Tipping paper, also known as cork paper, is a key auxiliary material in cigarette manufacturing that connects tobacco and filters. Its core functions include physical connection and auxiliary filtration. During processing, laser drilling is required on its surface. The micro-holes formed by laser drilling can dilute the concentration of the smoke inhaled during smoking, thereby effectively reducing the content of tar and carbon monoxide and meeting the health standards of the World Health Organization and various countries. The laser generates a high-energy beam, which forms a light spot through the focusing system. After the light energy is absorbed by the paper fibers, it is converted into heat energy, causing the paper to instantaneously heat up to over 1000 °C, directly gasifying components such as cellulose and lignin to form micro-holes.

[0003] A patent document with the publication number CN111975232B discloses a laser drilling machine for tipping paper graphic holes, including a frame, a controller, a winding and unwinding mechanism, an optical mechanism, and an operating table. The controller, the winding and unwinding mechanism, the optical mechanism, and the operating table are all arranged on the frame. The winding and unwinding mechanism, the optical mechanism, and the operating table are all signal-connected to the controller. The controller performs signal operation control through the operating table. The laser emitter assembly includes a laser optical seat, a laser emitter, an expander lens, a galvanometer, and a focusing field lens. Among them, the galvanometer is designed using high-stability precision position detection sensing technology and moving magnet and moving coil deflection working modes. The driver of the galvanometer adopts a new topology circuit design. Under the control of the controller, a servo signal is output to control the deflection of the galvanometer, thereby accurately scanning out a graphic. The operating table sends an operation instruction to the controller to control the optical mechanism to focus a high-energy density laser beam to punch a combination of graphic holes on the tipping paper tape through the galvanometer scanning, and at the same time rotate the rotary handwheel to adjust the optical path focal length.

[0004] However, the following problems still exist in this solution. There are multiple laser emitters. When the tipping paper is conveyed past the laser emitters, multiple laser emitters work together to uniformly form multiple laser holes on its surface. However, there are various specifications of tipping paper. For tipping paper of different specifications, the positions of the corresponding laser emitters need to be adjusted to adjust the distance between the laser holes. In the prior art, generally, multiple laser emitters are adjusted one by one manually, which is a cumbersome process and affects the drilling efficiency. Moreover, the adjusted laser emitters still need to maintain an equidistant distribution, and it is difficult to control the adjustment accuracy, resulting in difficulty in ensuring the quality of the formed holes. Summary of the Invention

[0005] The present invention provides a laser drilling machine for tipping paper processing, aiming to solve the problem in the related technology that it is inconvenient to adjust the position of the laser emitter according to different specifications of tipping paper.

[0006] The laser punching machine for processing tipping paper of the present invention comprises a laser emitter installed on a frame, wherein a plurality of laser emitters are arranged in a left-right arrangement along the conveying direction of the paper, and the plurality of laser emitters are distributed at equal distances along the front-back direction; An adjustment component is arranged on the frame, and the adjustment component includes: a toothed plate slidably assembled on the frame, and a plurality of middle pieces arranged corresponding to the plurality of laser emitters; the middle pieces include: a gear set, a screw rod rotatably connected to the frame, and an adjustment block connected to the laser emitter, the screw rod and the adjustment block thread cooperate to drive the laser emitter to move forward and backward, the gear set cooperates with the toothed plate and the screw rod respectively, the movement of the toothed plate drives the plurality of laser emitters to move synchronously through the gear set, the screw rod and the adjustment block, and the transmission ratio of two adjacent gear sets increases proportionally so that the distance between each two adjacent laser emitters in the front-to-back direction remains the same.

[0007] The effect is that after changing the paper of different specifications, the tooth plate is moved, and the tooth plate drives multiple adjustment blocks to move simultaneously through the gear group. When the adjustment block moves, the corresponding laser emitter is driven to move synchronously, and then the multiple laser emitters are driven to move in the front and rear directions at the same time to adjust the position of the hole. At the same time, the transmission ratio of the gear group corresponding to each two adjacent adjustment blocks is set to change proportionally, so that the speed of the two adjacent laser emitters when moving synchronously is different, so that the distance between the two adjacent laser emitters after adjustment remains the same, so that the position of the laser emitter can be adjusted quickly, and the adjusted punching position can be ensured to be evenly distributed to adapt to different specifications of paper and improve processing efficiency.

[0008] Preferably, the gear set includes: a first gear, a second gear, and a third gear. The first gear is coaxially connected to the second gear, the first gear is meshed with the gear plate, the third gear is coaxially connected to the screw, the second gear is meshed with the third gear, and the transmission ratio of the second gear to the third gear in multiple gear sets increases proportionally.

[0009] The effect is that the movement of the toothed plate drives the first gear to rotate, and the rotation of the first gear drives the second gear to rotate synchronously. The transmission ratios of the second gears in each gear set are different. When the toothed plate moves, the rotation speeds of the two adjacent screws are different, thereby driving the corresponding adjustment blocks to move to different distances.

[0010] Preferably, a plurality of conveying rollers are provided on the frame, a center point is provided below the conveying rollers, the plurality of conveying rollers are arranged in an arc shape around the center point, and the center point is provided on the side of the conveying roller away from the laser emitter, the conveying rollers are provided below the laser emitter, the plurality of laser emitters are also arranged in an arc shape around the center point, the laser emitters are arranged in a direction toward the center point, and the laser emitters correspond to the middle of every two adjacent conveying rollers.

[0011] The effect is that multiple conveying rollers are set to be arc-shaped so that when the paper is conveyed past the conveying rollers, the paper can closely adhere to the conveying rollers. That is, after the paper is conveyed to the laser emitter, the conveying rollers closely adhere to the paper to improve the stability of the paper, thereby improving the hole-making quality.

[0012] Preferably, a plurality of mounting sleeves are provided on the frame, and the plurality of mounting sleeves correspond to the plurality of laser emitters one by one. The adjusting block is slidably assembled back and forth in the mounting sleeve, and the mounting sleeve slides on the frame in the direction towards the conveying roller. A rack is provided between every two mounting sleeves. A fourth gear and a fifth gear that mesh with each other are rotatably assembled on the frame. The fourth gear and the fifth gear are respectively meshed with the racks on the two mounting sleeves to make the two mounting sleeves move synchronously.

[0013] The effect is that when one of the mounting sleeves is moved, the movement of the mounting sleeve drives the other mounting sleeves to move towards the center point through the rack, the fourth gear, and the fifth gear, and the moving distances are the same. Furthermore, the moving distances of the plurality of laser emitters are made the same at the same time, and the distance between the laser emitter and the paper is synchronously adjusted.

The fixing portion cooperates with the mounting sleeve, and the connecting portion cooperates with the screw. The connecting portion is slidably assembled on the fixing portion, and the sliding direction of the connecting portion is the same as the sliding direction of the mounting sleeve. The laser emitter is installed on the fixing portion.

[0015] The effect is that the rotation of the screw drives the connecting portion and the fixing portion to move, adjusting the position of the laser emitter. When the mounting sleeve moves, it drives the laser emitter to move through the fixing portion, and at the same time, the fixing portion moves relative to the connecting portion, that is, the connecting portion is in a fixed state when the mounting sleeve moves, so as to realize the adjustment of the laser emitter in two directions and reduce the phenomenon that the screw interferes with the movement of the mounting sleeve.

[0016] Preferably, the laser emitter includes: a first laser, a second laser, and a third laser. The second laser is located between the first laser and the third laser. The second laser is not connected to the toothed plate. Both the first laser and the third laser are connected to the adjusting block. There are two of both the first laser and the third laser. The thread directions of the screws on the first laser and the screws on the third laser are opposite.

[0017] The effect is that when the toothed plate moves, the screws corresponding to the first laser and the screws corresponding to the third laser rotate in opposite directions, and then drive both the first laser and the third laser to move away from the second laser at the same time, reducing the moving stroke of the toothed plate, so as to quickly synchronously adjust the distances between two adjacent first lasers, between the first laser and the second laser, between the second laser and the third laser, and between two adjacent third lasers, improving the adjustment efficiency.

[0018] Preferably, an installation block is provided on the second laser, and the second laser is arranged in the corresponding installation sleeve through the installation block. A tooth groove is formed in the installation block along the arrangement direction of the second laser. A housing covering the outside of the laser emitter is provided on the frame. A first handwheel is rotatably provided on the housing, and a sixth gear meshing with the tooth groove is coaxially provided on the first handwheel.

[0019] The effect is that by rotating the first handwheel, the first handwheel drives the installation block to move through the sixth gear, and the installation block drives one of the installation sleeves to move, thereby adjusting the positions of multiple installation sleeves simultaneously.

[0020] Preferably, a second handwheel is rotatably provided on the housing, and the second handwheel is coaxially connected to one of the second gears.

[0021] The effect is that by rotating the second handwheel, the second handwheel drives one of the second gears to rotate, the rotation of the second gear drives the tooth plate to move, and the movement of the tooth plate drives multiple adjusting blocks to move simultaneously to adjust the position of the laser adjuster.

[0022] Preferably, the tooth plate is set to be arc-shaped, and the center of the arc of the tooth plate coincides with the center point.

[0023] The effect is to facilitate the adjustment of the positions of multiple laser emitters arranged around the center point.

[0024] Preferably, a plurality of intermediate rollers for conveying paper are provided on the frame, and a dust removal cover is provided on the frame, and the dust removal cover covers the outside of the conveying roller.

[0025] The effect is that during laser drilling, the generated smoke is removed through the dust removal cover, reducing the phenomenon that the generated smoke or other impurities interfere with the drilling.

[0026] Beneficial effects: 1. In the present invention, by providing multiple groups of gear sets and screws, and multiple screws corresponding to multiple laser emitters one by one, the tooth plate cooperates with multiple groups of gear sets at the same time. When the tooth plate moves, multiple groups of gear sets drive multiple screws to rotate simultaneously, thereby driving multiple laser emitters to move simultaneously and adjusting the positions of multiple laser emitters at the same time.

[0027] 2. The transmission ratios of two adjacent groups of gear sets are increased proportionally, so that when two adjacent laser emitters move synchronously, their moving speeds are different. After the adjustment is completed, the distance between two adjacent laser emitters is still the same to adapt to different specifications of paper.

[0028] 3. When the installation sleeve moves, it drives the laser emitter to move towards the direction of the paper. A rack, a fourth gear, and a fifth gear are provided to make the moving directions of multiple installation sleeves the same, thereby realizing the adjustment of the positions of the laser emitters at the same time and the adjustment of the distance between the laser emitters and the paper.

[0030] 5. A first handwheel and a second handwheel are provided to adjust the positions of the installation sleeve and the toothed plate respectively, and then corresponding to the adjustments in two directions of the laser emitter, that is, the distance in the front-back direction between two adjacent laser emitters and the distance between the laser emitter and the paper. By rotating the first handwheel or the second handwheel respectively, the adjustment in the corresponding direction can be realized, simplifying the adjustment operation and improving the processing efficiency.

Detailed implementation manners

[0044] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0045] As Figures 1 to 12 shown, the laser drilling machine for tipping paper processing of the present invention includes: a punching component 2, a conveying component 3, and an adjusting component 4 provided on a frame 1. The conveying component 3 is used for conveying paper 01 so that the paper 01 passes through the punching component 2 during conveyance and then undergoes a punching operation by the punching component 2. The adjusting component 4 is connected to the punching component 2. When it is necessary to punch papers 01 of different specifications, the punching position is adjusted by the adjusting component 4 to adapt to papers 01 of different specifications.

[0046] Refer to Figure 1 、 Figure 2 、 Figure 3, the punching component 2 includes a plurality of laser emitters 21. The emission end of the laser emitter 21 faces downward. The conveying component 3 is arranged below the laser emitter 21. The conveying component 3 drives the paper 01 to be conveyed past the laser emitter 21, and the punching operation is performed through the laser emitter 21. The plurality of laser emitters 21 are arranged along the conveying direction of the paper 01. The paper 01 is conveyed to the right, that is, the plurality of laser emitters 21 are arranged in the left-right direction, and the plurality of laser emitters 21 are equidistantly distributed in the front-back direction, so that the holes punched by the plurality of laser emitters 21 are evenly distributed on the paper 01.

[0047] When punching papers 01 of different specifications, it is necessary to adjust the punching position according to the width of the paper 01, that is, it is necessary to adjust the distance between the front and back of every two adjacent laser emitters 21.

[0048] Refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 , the adjusting component 4 includes: a toothed plate 5 and an intermediate member 6. An installation groove 11 for installing the toothed plate 5 is provided on the frame 1. The toothed plate 5 is assembled in the installation groove 11, and the toothed plate 5 is slidably assembled on the frame 1 through the installation groove 11. The intermediate member 6 includes: a gear set 61, a screw 62, and an adjusting block 63. The adjusting block 63 is slidably assembled on the frame 1 in the front-back direction. The screw 62 is rotatably assembled on the frame 1. The screw 62 passes through the adjusting block 63, and the screw 62 is in threaded cooperation with the adjusting block 63. That is, when the screw 62 rotates, the position of the adjusting block 63 can be adjusted. The laser emitter 21 is installed on the adjusting block 63. The gear set 61 is arranged on the frame 1 and is respectively connected to the screw 62 and the toothed plate 5. A plurality of intermediate members 6 are provided, and the plurality of intermediate members 6 are arranged in one-to-one correspondence with the plurality of laser emitters 21. The plurality of intermediate members 6 cooperate with the toothed plate 5 at the same time.

[0049] When moving the toothed plate 5, the plurality of gear sets 61 drive the plurality of screws 62 to rotate at the same time. The plurality of screws 62 rotate and then drive the plurality of adjusting blocks 63 to move at the same time, thereby adjusting the positions of the plurality of laser emitters 21 at the same time.

[0050] Refer to Figure 5 、 Figure 6 、 Figure 7, the transmission ratios of the gear sets 61 in multiple middleware 6 increase in a geometric progression, so that when the toothed plate 5 moves, the number of turns of the screw 62 corresponding to each laser emitter 21 is different, and further the moving distance of the laser emitter 21 corresponds to the transmission ratio of the gear set 61. While realizing the synchronous movement of multiple laser emitters 21, the moving speeds of two adjacent laser emitters 21 are different. After adjusting the positions of the laser emitters 21, the distance between every two laser emitters 21 in the front-back direction is kept the same. That is, while adjusting the positions of the laser holes according to papers 01 of different passing specifications, the distance between every two adjacent columns of laser holes is still kept the same, improving the adjustment efficiency while ensuring the hole-forming quality.

[0051] Refer to Figure 5 , Figure 6 , Figure 7 , the gear set 61 includes: a first gear 611, a second gear 612, and a third gear 613. The first gear 611 and the second gear 612 are both rotatably assembled on the frame 1, and the first gear 611 and the second gear 612 are coaxially connected. The first gear 611 meshes with the toothed plate 5. The third gear 613 is coaxially connected with the screw 62, and the third gear 613 meshes with the second gear 612. The transmission ratios of the second gear 612 and the third gear 613 in every two adjacent gear sets 61 increase in a geometric progression, that is, the sizes of the second gears 612 in each gear set 61 are different. When the toothed plate 5 moves, it drives the adjusting block 63 to move at different speeds.

[0052] When the toothed plate 5 moves, it drives the first gear 611 to rotate. The first gear 611 rotates to drive the second gear 612 to rotate. The second gear 612 rotates to drive the third gear 613 and the screw 62 to rotate, and the positions of the laser emitters 21 are adjusted.

[0053] Refer to Figure 2 , Figure 3 , Figure 8 , multiple laser emitters 21 are respectively divided into: a first laser 211, a second laser 212, and a third laser 213. The first laser 211, the second laser 212, and the third laser 213 are arranged along the conveying direction of the paper 01. The second laser 212 is located between the first laser 211 and the third laser 213. The second laser 212 is not connected to the adjusting block 63. That is, when the toothed plate 5 rotates, the second laser 212 is fixed. There are two first lasers 211 and two third lasers 213. Both the first laser 211 and the third laser 213 are connected to the adjusting block 63, and the screw 62 on the first laser 211 has the opposite thread direction to the screw 62 on the third laser 213.

[0054] When the toothed plate 5 moves, since the second laser 212 is not connected to the toothed plate 5, it remains stationary. Under the action of the screw 62, both the first laser 211 and the third laser 213 move away from the second laser 212 in opposite directions. That is, when adjusting the position of the laser emitter 21, the second laser 212 is aligned with the center of the paper 01. As the toothed plate 5 moves, the first laser 211 and the third laser 213 move with the second laser 212 as the center. Moreover, the transmission ratios of the adjacent gear sets 61 are different, so that the moving speeds of the two first lasers 211 or the third lasers 213 are also different. Setting the first laser 211 and the second laser 212 to move in opposite directions can reduce the moving range of the toothed plate 5, so as to quickly adjust each laser emitter 21 to the specified position.

[0055] Refer to Figure 2 、 Figure 9 As shown in FIGS. 7 and 8, a housing 7 is provided on the frame 1. The housing 7 is sleeved outside the laser emitter 21. A second handwheel 9 is rotatably provided on the housing 7. The rotation shaft of the second handwheel 9 passes through the housing 7 and is connected to one of the second gears 612. The second handwheel 9 is coaxially connected to the second gear 612. When it is necessary to adjust the position of the laser emitter 21, by rotating the second handwheel 9 to drive one of the second gears 612 to rotate, the toothed plate 5 is driven to move, and then a plurality of screws 62 are driven to rotate simultaneously to adjust the positions of the plurality of laser emitters 21.

[0056] The conveying assembly 3 includes: a conveying roller 31 and an intermediate roller 32. The conveying roller 31 and the intermediate roller 32 are both rotatably assembled on the frame 1. A plurality of conveying rollers 31 and intermediate rollers 32 are provided. The intermediate roller 32 is used to place the paper roll 01 and convey the paper 01. A center point 02 is provided below the plurality of conveying rollers 31. The plurality of conveying rollers 31 are arranged in an arc around the center point 02. The conveying rollers 31 are arranged below the laser emitter 21. The plurality of laser emitters 21 are also arranged in an arc around the center point 02 and are concentric with the plurality of conveying rollers 31. The laser emitters 21 are all arranged in the direction of the center point 02. The laser emitters 21 and the conveying rollers 31 are arranged at an interval in the vertical direction. The laser emitters 21 correspond to the middle of every two adjacent conveying rollers 31.

[0057] Refer to Figure 1 As shown in FIGS. 10 and 11, a plurality of conveying rollers 31 are arranged in an arc around the center point 02 so that the paper 01 can be conveyed closely against the conveying rollers 31 when the paper 01 is conveyed through the conveying rollers 31. When the paper 01 passes through the laser emitter 21, the paper 01 is punched. And the laser emitter 21 is arranged corresponding to the middle of two conveying rollers 31 to avoid the phenomenon that the conveying rollers 31 interfere with the punching.

[0058] Refer to Figure 3 、 Figure 5The toothed plate 5 is also arranged to be arc-shaped, and the center of the circle of the toothed plate 5 coincides with the center point 02, so that the toothed plate 5 can adjust the positions of multiple laser emitters 21 simultaneously when moving.

[0059] Reference Figure 1 A dust cover 12 is provided on the frame 1, and an exhaust pipe 121 is provided below the dust cover 12. One end of the exhaust pipe 121 away from the dust cover 12 is connected to an exhaust pump. The dust cover 12 is sleeved on the outside of the conveying roller 31. When laser drilling is performed, the exhaust pump exhausts air through the exhaust pipe 121 and the dust cover 12 to treat the generated smoke.

[0060] When punching paper 01 of different thickness specifications, or in order to ensure the quality of the holes, it is necessary to adjust the distance between the laser emitter 21 and the paper 01 .

[0061] Reference Figure 10 , Figure 11 , Figure 12 , a plurality of mounting sleeves 13 are arranged on the frame 1, and the plurality of mounting sleeves 13 and the plurality of laser emitters 21 are arranged one by one, and the adjustment block 63 is slidably assembled in the mounting sleeve 13, and the mounting sleeve 13 is slidably assembled on the frame 1, and the mounting sleeve 13 slides in the direction toward the conveying roller 31, that is, the mounting sleeve 13 moves in the direction toward the center point 02. A rack 14 is arranged on one side of the mounting sleeve 13 close to another mounting sleeve 13, and the rack 14 is arranged along the sliding direction of the mounting sleeve 13. A fourth gear 15 and a fifth gear 16 are rotatably assembled on the frame 1, and the fourth gear 15 and the fifth gear 16 are meshed, and the fourth gear 15 and the fifth gear 16 are arranged between two adjacent mounting sleeves 13, and the fourth gear 15 and the fifth gear 16 are respectively meshed with the racks 14 on the two mounting sleeves 13. When one of the mounting sleeves 13 is moved, the rack 14, the fourth gear 15 and the fifth gear 16 are used to simultaneously drive multiple mounting sleeves 13 to move toward the conveying roller 31, thereby adjusting the positions of multiple laser emitters 21 at the same time, and ensuring that each laser emitter 21 moves the same distance, that is, each laser emitter 21 is at the same distance from the paper 01, thereby ensuring the overall hole-forming quality of the paper.

[0062] Reference Figure 4 The adjusting block 63 includes a connecting portion 631 and a fixing portion 632. The fixing portion 632 is slidably matched with the mounting sleeve 13. The connecting portion 631 is arranged above the fixing portion 632 and is slidably matched with the fixing portion 632. The sliding direction of the connecting portion 631 is the same as the sliding direction of the mounting sleeve 13. The screw 62 is connected to the connecting portion 631, and the laser emitter 21 is arranged on the fixing portion 632. When the mounting sleeve 13 slides, the laser emitter 21 is driven to move by the fixing portion 632, and the connecting portion 631 is fixed at the same time, so as to reduce the phenomenon that the screw 62 interferes with the movement of the laser emitter 21.

[0063] Both the first laser 211 and the third laser 213 are assembled in the mounting sleeve 13 through the adjusting block 63. An installation block 17 is provided on the second laser 212, and the installation block 17 is connected to the corresponding mounting sleeve 13, that is, the second laser 212 is connected to the mounting sleeve 13 through the installation block 17.

[0064] Refer to Figure 1 、 Figure 12 A middle groove is penetrated through the installation block 17, and a toothed groove 171 is provided on the inner wall of the middle groove. The toothed groove 171 is arranged along the sliding direction of the mounting sleeve 13. A first handwheel 8 is rotatably arranged on the housing 7. The end of the first handwheel 8 passes through the housing 7 and extends to the middle groove. A sixth gear 81 is coaxially arranged at the rotating shaft of the first handwheel 8, and the sixth gear 81 meshes with the toothed groove 171.

[0065] Rotate the first handwheel 8. The first handwheel 8 drives the installation block 17 to move through the sixth gear 81. The installation block 17 drives the mounting sleeve 13 on the second laser 212 to move, and then drives a plurality of mounting sleeves 13 to move simultaneously, so as to adjust the positions of a plurality of laser emitters 21 at the same time.

[0066] In addition, a distance sensor can be arranged below the fixing part 632. The distance sensor is used to detect the distance between the fixing part and the paper 01, and further detect the distance between the laser emitting end of the laser emitter 21 and the paper 01. A controller and a display screen can also be correspondingly arranged on the frame 1. The signal receiving end of the controller is electrically connected to the signal output end of the distance sensor, and the control end of the controller is connected to the display screen. The distance sensor transmits the detected distance information to the controller. After the controller processes the signal, the distance detected by the distance sensor is displayed on the display screen, so as to monitor the distance between the laser emitter 21 and the paper 01 in real time during adjustment, so as to adaptively adjust the distance between the laser emitter 21 and the paper 01 according to the actual hole forming quality.

[0067] The implementation principle of the present invention is: when it is necessary to adjust the punching distance according to different specifications of the paper 01, rotate the second handwheel 9. The second handwheel 9 drives the toothed plate 5 through the second gear 612. The toothed plate 5 drives a plurality of screw rods 62 to rotate at the same time. The rotation of the screw rods 62 adjusts the positions of a plurality of laser emitters 21 through the adjusting block 63 at the same time. In addition, by setting different transmission ratios of each group of gear sets 61, the rotation speeds of two adjacent screw rods 62 and the moving speeds of the adjusting block 63 are different. When the laser emitter 21 moves, the distance between two adjacent laser emitters 21 remains the same, so that the adjusted punching positions are evenly distributed on the paper 01, ensuring the hole forming quality.

[0068] In addition, the first handwheel 8 can be rotated to drive the sixth gear 81 to rotate. The rotation of the sixth gear 81 drives the mounting block 17 and the mounting sleeve 13 to move, so as to adjust the positions of a plurality of mounting sleeves 13 at the same time, so that the distances that a plurality of laser emitters 21 move towards the conveying roller 31 are the same.

[0069] When processing papers 01 of different specifications, the first handwheel 8 and the second handwheel 9 can be used to quickly adjust the laser emitter 21, and the distances between two adjacent punching positions after adjustment are the same. The operation is simple and fast. At the same time, the hole forming quality can be guaranteed and the processing efficiency can be improved.

[0070] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
