Description

Technical Field

[0001] The invention relates to the technical field of cigarette punching, and in particular to a conveying device for assisting laser punching. Background Art

[0002] During the laser drilling process, the cigarettes are squeezed by the drilling drum and the cigarette roller, causing some tobacco to fall from the lighting end of the cigarette, resulting in tobacco protrusion or loose and empty cigarette heads, which not only affects the appearance quality of the cigarettes, but also has an adverse effect on the combustion performance and taste of the cigarettes. The laser emitted by the laser acts on the cigarettes on the drilling drum. Since the drilling drum absorbs the cigarettes on the drilling drum through negative pressure, it is difficult for the cigarettes to rotate, so it is difficult to achieve multi-angle drilling of cigarettes. Summary of the invention

[0003] The purpose of the present invention is to provide a conveying device for assisting laser punching, and the technical problem to be solved is how to achieve multi-angle punching of cigarettes.

[0004] The present invention is achieved through the following technical solutions:

[0005] A conveying device for assisting laser drilling includes a silo, a drum assembly, a clamping assembly, a rotating assembly, a moving assembly, and a laser assembly;

[0006] A sorting component is provided at the bottom of the silo, and the sorting component is used to arrange the cigarettes;

[0007] The drum assembly comprises a drum group and a drum driving device, the drum group is connected to the drum driving device, and the drum driving device is used to drive the drum group to rotate;

[0008] The discharge end of the above-mentioned sorting assembly corresponds to the side wall of the drum assembly;

[0009] The side wall of the drum assembly is provided with a negative pressure duct, and a negative pressure device is provided inside the drum assembly. The negative pressure device is provided corresponding to the negative pressure duct; the negative pressure device is used to generate negative pressure so that the negative pressure duct absorbs cigarettes;

[0010] The clamping assembly is arranged on the rotating assembly, the clamping assembly is used to clamp the cigarette from the negative pressure duct, and the rotating assembly is used to drive the clamping assembly to rotate;

[0011] The rotating assembly is arranged on the moving assembly, and the moving assembly is used to drive the rotating assembly to move;

[0012] A punching area is arranged beside the drum wheel assembly, and the laser assembly is facing the punching area. The laser assembly is used to emit laser to punch holes in the cigarettes in the punching area when the moving assembly and / or the rotating assembly drives the cigarettes to move to the punching area.

[0013] The combination of the above-mentioned drum wheel assembly and negative pressure technology ensures the stable transportation and adsorption of cigarettes. A negative pressure wind slot adsorbs a cigarette, discretizes and fixes the cigarette, and facilitates the subsequent clamping assembly to clamp a single cigarette; the above-mentioned rotating assembly drives the clamping assembly to rotate around the axis of the cigarette, and the above-mentioned moving assembly moves the entire rotating assembly along a straight line or a specific path, so that the laser can also perform positioning and punching in the length direction of the cigarette, increasing the longitudinal flexibility of punching; when the rotating assembly rotates the cigarette, any point on the circumference of the cigarette can enter the punching area, so that the laser emitted by the laser can perform punching operations at any point on the circumference of the cigarette, realizing multi-angle punching of the cigarette.

[0014] Furthermore, the sorting assembly comprises two vertical plates and two baffles arranged in parallel, and the baffles and the vertical plates are combined to form a sorting channel;

[0015] The distance between the two vertical plates is greater than the diameter of the cigarette, and the distance between the two baffles is greater than the length of the cigarette;

[0016] The bottom of the silo is provided with a discharge port, and the vertical plate is connected to the bottom of the silo;

[0017] The sorting channel is connected with the silo through the discharge port.

[0018] The vertical plates and baffles mentioned above enclose a sorting channel, and the cigarettes entering the sorting channel are arranged through physical guidance to ensure that the cigarettes move in a predetermined direction and order; the spacing between the parallel vertical plates is designed to be larger than the diameter of the cigarette, and the spacing between the baffles is larger than the length of the cigarette, allowing a single cigarette to pass smoothly without being squeezed, keeping the appearance of the cigarette intact; at the same time, ensure that the length direction of the cigarette is parallel to the width direction of the vertical plates, and adjust the direction of the cigarette in the sorting channel; the discharge port at the bottom of the above-mentioned silo is directly connected to the sorting channel, and when the cigarettes fall from the silo, they can directly enter the sorting channel, which simplifies the material transmission process, avoids unnecessary complex transition links, and helps to maintain the continuity and stability of the cigarette arrangement; the above-mentioned sorting component realizes the preliminary sorting and sorting of the cigarettes. When the cigarettes fall from the silo to the sorting channel, they are automatically aligned and arranged in order under the guidance of the vertical plates and baffles.

[0019] Furthermore, the drum assembly includes a first drum and a second drum, and a side wall of the first drum contacts a side wall of the second drum;

[0020] The side wall of the first drum wheel corresponds to the vertical plate, and a gap is left between the end of the vertical plate and the side wall of the first drum wheel, and the cigarette part extending out of the negative pressure duct passes through the gap;

[0021] The first drum wheel and the second drum wheel are rotated synchronously, and when a negative pressure air slot on the first drum wheel is located directly below the first drum wheel, a negative pressure air slot on the second drum wheel is located directly above the second drum wheel.

[0022] The above-mentioned drum wheel group includes a first drum wheel and a second drum wheel, and the side walls of the first drum wheel and the second drum wheel are in contact with each other, forming a continuous cigarette transfer path, so that the cigarettes can be seamlessly connected during the transfer from the first drum wheel to the second drum wheel; the side wall of the above-mentioned first drum wheel corresponds to the vertical plate, and after the cigarette is adsorbed by the negative pressure air groove, the part of the cigarette that exceeds the negative pressure air groove needs to pass through the gap between the vertical plate and the side wall of the first drum wheel. In order to ensure that the cigarette can be transferred from the first drum wheel to the second drum wheel, the negative pressure air groove on the first drum wheel needs to be aligned with the negative pressure air groove on the second drum wheel. When a negative pressure air groove on the first drum wheel rotates to the lowest point (i.e., directly below), there must be a negative pressure air groove on the second drum wheel at the highest point (i.e., directly above), and the negative pressure air groove at the highest point of the second drum wheel is aligned with the negative pressure air groove at the lowest point of the first drum wheel, ensuring a smooth transition of the cigarette between the two drum wheels.

[0023] In summary, the double-drum design, combined with the negative pressure system and synchronous rotation mechanism, optimizes the positioning and control of cigarettes during the transmission process.

[0024] Furthermore, when the negative pressure duct directly below the first drum wheel faces the negative pressure duct directly above the second drum wheel, the negative pressure device corresponding to the negative pressure duct directly below the first drum wheel is closed.

[0025] At the moment when the cigarette is about to be transferred from the first drum to the second drum, the negative pressure of the negative pressure air slot directly below the first drum is closed to weaken or eliminate the adsorption force of the first drum on the cigarette, ensuring that the cigarette can be smoothly and steadily caught by the negative pressure air slot on the second drum; closing the negative pressure in time can prevent the cigarette from being pulled or stuck unnecessarily due to the double negative pressure adsorption of the two drums during the transfer process, thereby reducing the risk of deformation or damage of the cigarette and protecting the integrity of the cigarette.

[0026] Further, the front end surface of the first drum wheel extends beyond the front end surface of the second drum wheel;

[0027] The clamping assembly is located in front of the second drum wheel, and the clamping assembly clamps the cigarette in the negative pressure wind slot on the second drum wheel from the front end surface of the second drum wheel.

[0028] The front end surface of the first drum wheel extends beyond the front end surface of the second drum wheel. After the cigarette transitions from the first drum wheel to the second drum wheel, the end of the cigarette extends out of the front end surface of the second drum wheel. The clamping assembly is arranged directly in front of the second drum wheel. After the cigarette enters the control range of the second drum wheel, the part of the cigarette extending out of the front end surface of the second drum wheel can be grasped by the clamping assembly.

[0029] Furthermore, it also includes a sensor, wherein the sensor is connected to the laser assembly;

[0030] The sensor is used to collect information about cigarettes in the perforated area, and emits a laser signal when collecting information about cigarettes in the perforated area;

[0031] The laser assembly is used to emit laser when receiving a laser signal.

[0032] The above-mentioned sensor is used to monitor in real time whether there is a cigarette in the punching area. If so, a laser signal is immediately sent to the laser component to avoid aimless punching.

[0033] Furthermore, the laser assembly comprises a laser, a galvanometer group and a focusing head, and the galvanometer group is arranged between the laser and the focusing head;

[0034] The laser is connected to the sensor. When receiving a laser signal, the laser emits a laser. The laser is incident on the galvanometer group, and the galvanometer group deflects the laser to obtain a first deflected laser.

[0035] The focusing head is facing the punching area, and is used to receive a first deflected laser. The first deflected laser is deflected by the focusing head to obtain a second deflected laser. The second deflected laser is incident on the cigarettes in the punching area to punch holes in the cigarettes in the punching area.

[0036] The above laser is directly connected to the sensor to form a closed-loop control system. When the sensor detects that the cigarette is in place and sends out a laser signal, the laser responds quickly and starts to emit laser. This instant response mechanism ensures the timeliness and accuracy of laser drilling. The above galvanometer is usually driven by a high-speed motor, which can quickly change the direction of the laser according to the control signal to achieve the regulation of the direction of the laser beam. When the laser is incident on the galvanometer group, the original laser is deflected into the first deflected laser through microsecond-level angle adjustment, which is convenient for flexible selection and rapid adjustment of the drilling position. The above focusing head not only receives the first deflected laser from the galvanometer group, but also further deflects it to form a second deflected laser. Through the joint adjustment of the galvanometer group and the focusing head, it can achieve rapid adaptation to different cigarette specifications and different drilling requirements. Whether it is single-point drilling or multi-point and multi-angle drilling, it can be completed quickly and accurately.

[0037] Furthermore, a conveyor belt is provided below the moving assembly, and the conveyor belt is used for conveying cigarettes.

[0038] The above-mentioned conveyor belt provides a continuous and stable cigarette conveying platform, ensuring that the cigarettes can leave the punching process after laser punching, maintaining the continuous fluidity of the production line.

[0039] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0040] The combination of the above-mentioned drum wheel assembly and negative pressure technology ensures the stable transportation and adsorption of cigarettes. A negative pressure wind slot adsorbs a cigarette, discretizes and fixes the cigarette, and facilitates the subsequent clamping assembly to clamp a single cigarette; the above-mentioned rotating assembly drives the clamping assembly to rotate around the axis of the cigarette, and the above-mentioned moving assembly moves the entire rotating assembly along a straight line or a specific path, so that the laser can also perform positioning and punching in the length direction of the cigarette, increasing the longitudinal flexibility of punching; when the rotating assembly rotates the cigarette, any point on the circumference of the cigarette can enter the punching area, so that the laser emitted by the laser can perform punching operations at any point on the circumference of the cigarette, realizing multi-angle punching of the cigarette.

[0050] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0051] Example 1

[0052] Combination Figures 1 to 5 , this embodiment 1 provides a conveying device for assisting laser drilling, including a silo 10, a drum assembly 20, a clamping assembly 30, a rotating assembly 40, a moving assembly 50 and a laser assembly 70;

[0053] A sorting assembly 80 is provided at the bottom of the silo 10, and the sorting assembly 80 is used to arrange cigarettes;

[0054] The drum assembly 20 includes a drum group and a drum driving device 24. The drum group is connected to the drum driving device 24. The drum driving device 24 is used to drive the drum group to rotate.

[0055] The discharge end of the sorting assembly 80 corresponds to the side wall of the drum assembly;

[0056] The side wall of the drum assembly is provided with a negative pressure duct 23, and a negative pressure device is provided inside the drum assembly. The negative pressure device is provided corresponding to the negative pressure duct 23; the negative pressure device is used to generate negative pressure so that the negative pressure duct 23 absorbs cigarettes;

[0057] The clamping assembly 30 is disposed on the rotating assembly 40. The clamping assembly 30 is used to clamp the cigarette from the negative pressure duct 23. The rotating assembly 40 is used to drive the clamping assembly 30 to rotate.

[0058] The rotating assembly 40 is disposed on the moving assembly 50, and the moving assembly 50 is used to drive the rotating assembly 40 to move;

[0059] A punching area is arranged beside the drum wheel assembly, and the laser assembly 70 is facing the punching area. The laser assembly 70 is used to emit laser to punch holes in the cigarettes in the punching area when the moving assembly 50 and / or the rotating assembly 40 drives the cigarettes to move to the punching area.

[0060] The combination of the drum assembly 20 and the negative pressure technology ensures the stable transportation and adsorption of cigarettes. A negative pressure wind slot 23 adsorbs a cigarette, discretizes and fixes the cigarette, and facilitates the subsequent clamping assembly 30 to clamp a single cigarette; the rotating assembly 40 drives the clamping assembly 30 to rotate around the axis of the cigarette, and the moving assembly 50 moves the entire rotating assembly 40 along a straight line or a specific path, so that the laser can also perform positioning and punching in the length direction of the cigarette, increasing the longitudinal flexibility of the punching; when the rotating assembly 40 rotates the cigarette, any point on the circumference of the cigarette can enter the punching area, so that the laser emitted by the laser 71 can perform a punching operation at any point on the circumference of the cigarette, realizing multi-angle punching of the cigarette.

[0061] The above-mentioned rotating component 40 can set the rotation angle so that the directional laser enters the cigarette from different angles when the cigarette rotates; the rotation angle range and speed of the rotating component 40 can be programmed to achieve precise punching at different positions and angles of the cigarette; the laser emitted by the above-mentioned laser component 70 can be programmed to control its focus and power, so as to form high-quality holes at different depths and angles of the cigarette, allowing the diameter, depth and layout of the punching to be adjusted as needed to meet different smoking characteristics requirements; the conveying device can also be equipped with a control system that can coordinate the operation of various components (such as drum drive, movement of the rotating component 40, laser emission, etc.) to ensure the synchronization of the punching operation; through preset programs or real-time adjustments, the punching position and angle of the cigarette can be fine-tuned to achieve a multi-angle, high-precision punching effect.

[0062] Example 2

[0063] Based on Example 1, Figure 2 and Figure 3 The sorting assembly 80 includes two vertical plates 81 and two baffles 82 arranged in parallel, and the baffles 82 and the vertical plates 81 are enclosed to form a sorting channel 83;

[0064] The distance between the two vertical plates 81 is greater than the diameter of the cigarette, and the distance between the two baffles 82 is greater than the length of the cigarette;

[0065] The bottom of the silo 10 is provided with a discharge port, and the vertical plate 81 is connected to the bottom of the silo 10;

[0066] The sorting channel 83 is connected to the silo 10 through the discharge port.

[0067] The vertical plates 81 and baffles 82 are used to enclose a sorting channel 83, and the cigarettes entering the sorting channel 83 are arranged by physical guidance to ensure that the cigarettes move in a predetermined direction and order. The spacing between the parallel vertical plates 81 is designed to be larger than the diameter of the cigarette, and the spacing between the baffles 82 is larger than the length of the cigarette, allowing a single cigarette to pass smoothly without being squeezed, keeping the appearance of the cigarette intact. At the same time, the length direction of the cigarette is ensured to be parallel to the width direction of the vertical plates 81, and the direction of the cigarette is adjusted in the sorting channel 83. The discharge port at the bottom of the silo 10 is directly connected to the sorting channel 83. When the cigarettes fall from the silo 10, they can directly enter the sorting channel 83, which simplifies the material transmission process, avoids unnecessary complex transition links, and helps to maintain the continuity and stability of the cigarette arrangement. The sorting component 80 realizes the preliminary sorting and sorting of the cigarettes. When the cigarettes fall from the silo 10 to the sorting channel 83, the cigarettes are automatically aligned and arranged in order under the guidance of the vertical plates 81 and the baffles 82.

[0068] Example 3

[0069] Based on Example 2, Figure 1 and Figure 2 The drum assembly includes a first drum 21 and a second drum 22, and the side wall of the first drum 21 is in contact with the side wall of the second drum 22;

[0070] The side wall of the first drum wheel 21 corresponds to the vertical plate 81. A gap is left between the end of the vertical plate 81 and the side wall of the first drum wheel 21. The cigarette part extending out of the negative pressure duct 23 passes through the gap.

[0071] The first drum wheel 21 and the second drum wheel 22 are rotated synchronously. When a negative pressure air slot 23 on the first drum wheel 21 is located directly below the first drum wheel 21 , a negative pressure air slot 23 on the second drum wheel 22 is located directly above the second drum wheel 22 .

[0072] The drum assembly comprises a first drum 21 and a second drum 22. The side walls of the first drum 21 and the second drum 22 are in contact with each other, forming a continuous cigarette transfer path, so that the cigarettes can be seamlessly connected during the process of being transferred from the first drum 21 to the second drum 22; the side wall of the first drum 21 corresponds to the vertical plate 81, and after the cigarette is adsorbed by the negative pressure air slot 23, the part of the cigarette that exceeds the negative pressure air slot 23 needs to pass through the gap between the vertical plate 81 and the side wall of the first drum 21. In order to ensure that the cigarette can be transferred from the first drum 21 to the second drum 22, the side wall of the first drum 21 corresponds to the vertical plate 81. The negative pressure wind slot 23 on the first drum wheel 21 is transferred to the second drum wheel 22, and the negative pressure wind slot 23 on the first drum wheel 21 needs to be aligned with the negative pressure wind slot 23 on the second drum wheel 22. When a negative pressure wind slot 23 on the first drum wheel 21 rotates to the lowest point (i.e. directly below), there must be a negative pressure wind slot 23 on the second drum wheel 22 at the highest point (i.e. directly above). The negative pressure wind slot 23 at the highest point of the second drum wheel 22 is aligned with the negative pressure wind slot 23 at the lowest point of the first drum wheel 21, ensuring a smooth transition of the cigarette between the two drum wheels.

[0073] In summary, the double-drum design, combined with the negative pressure system and synchronous rotation mechanism, optimizes the positioning and control of cigarettes during the transmission process.

[0074] In a specific embodiment, when the negative pressure duct 23 directly below the first drum wheel 21 faces the negative pressure duct 23 directly above the second drum wheel 22 , the negative pressure device corresponding to the negative pressure duct 23 directly below the first drum wheel 21 is closed.

[0075] At the moment when the cigarette is about to be transferred from the first drum 21 to the second drum 22, the negative pressure of the negative pressure slot 23 directly below the first drum 21 is closed to weaken or eliminate the adsorption force of the first drum 21 on the cigarette, thereby ensuring that the cigarette can be smoothly and steadily caught by the negative pressure slot 23 on the second drum 22; timely closing of the negative pressure can prevent the cigarette from being pulled or stuck unnecessarily due to the double negative pressure adsorption of the two drums during the transfer process, thereby reducing the risk of deformation or damage of the cigarette and protecting the integrity of the cigarette.

[0076] Example 4

[0077] Based on Example 3, Figure 2 , the front end surface of the first drum wheel 21 extends beyond the front end surface of the second drum wheel 22;

[0078] The clamping assembly 30 is located in front of the second drum 22 . The clamping assembly 30 clamps the cigarette in the negative pressure duct 23 on the second drum 22 from the front end surface of the second drum 22 .

[0079] The front end face of the first drum 21 extends beyond the front end face of the second drum 22. After the cigarette transitions from the first drum 21 to the second drum 22, the end of the cigarette extends out of the front end face of the second drum 22. The clamping assembly 30 is arranged directly in front of the second drum 22. After the cigarette enters the control range of the second drum 22, the part of the cigarette extending out of the front end face of the second drum 22 can be grasped by the clamping assembly 30.

[0080] The above-mentioned clamping assembly 30 clamps the cigarette from the lowest point of the second drum wheel 22. When a negative pressure wind slot 23 of the above-mentioned second drum wheel 22 rotates to the lowest point (at this time, the clamping assembly 30 has clamped the cigarette stably), the negative pressure device corresponding to the negative pressure wind slot 23 at the lowest point of the second drum wheel 22 is closed to prevent the cigarette from being unnecessary pulled or stuck due to the clamping force of the clamping assembly 30 and the negative pressure adsorption of the second drum wheel 22 during the transfer process, thereby reducing the risk of deformation or damage of the cigarette and protecting the integrity of the cigarette.

[0081] When the negative pressure duct 23 of the second drum wheel 22 rotates to the highest point, the negative pressure device corresponding to the negative pressure duct 23 is opened; after the negative pressure duct 23 on the first drum wheel 21 passes through the lowest point of the first drum wheel 21, the negative pressure device corresponding to the negative pressure duct 23 can be opened.

[0082] Example 5

[0083] On the basis of embodiment 1, a sensor is further included (the sensor may be a photoelectric sensor), and the sensor is connected to the laser assembly 70;

[0084] The sensor is used to collect information about cigarettes in the perforated area, and emits a laser signal when collecting information about cigarettes in the perforated area;

[0085] The laser assembly 70 is used to emit laser when receiving a laser signal.

[0086] The sensor is used to monitor in real time whether there is a cigarette in the punching area. If there is a cigarette, a laser signal is immediately sent to the laser assembly 70 to avoid non-target punching.

[0087] In a specific embodiment, the laser assembly 70 includes a laser 71, a galvanometer group 72 and a focusing head 73. The galvanometer group 72 is arranged between the laser 71 and the focusing head 73. Figure 6 ;

[0088] The laser 71 is connected to the sensor. When receiving a laser signal, the laser 71 emits a laser. The laser is incident on the galvanometer group 72. The galvanometer group 72 deflects the laser to obtain a first deflected laser.

[0089] The focusing head 73 is facing the punching area. The focusing head 73 is used to receive a first deflected laser. The first deflected laser is deflected by the focusing head 73 to obtain a second deflected laser. The second deflected laser is incident on the cigarettes in the punching area to punch holes in the cigarettes in the punching area.

[0090] The laser 71 is directly connected to the sensor to form a closed-loop control system. When the sensor detects that the cigarette is in place and sends a laser signal, the laser 71 responds quickly and starts to emit laser. This instant response mechanism ensures the timeliness and accuracy of laser drilling. The galvanometer is usually driven by a high-speed motor, which can quickly change the direction of the laser according to the control signal to achieve the regulation of the direction of the laser beam. When the laser is incident on the galvanometer group 72, the original laser is deflected into a first deflected laser through microsecond-level angle adjustment, which is convenient for flexible selection and rapid adjustment of the drilling position. The focusing head 73 not only receives the first deflected laser from the galvanometer group 72, but also further deflects it to form a second deflected laser. Through the joint adjustment of the galvanometer group 72 and the focusing head 73, it can achieve rapid adaptation to different cigarette specifications and different drilling requirements. Whether it is single-point drilling or multi-point and multi-angle drilling, it can be completed quickly and accurately.

[0091] Example 6

[0092] On the basis of Example 1, a conveyor belt 60 is provided below the moving assembly 50 , and the conveyor belt 60 is used to convey the punched cigarettes.

[0093] Example 1, after the punching is completed, the clamping assembly 30 transports the cigarette to the conveyor belt 60, and the conveyor belt transports the cigarette away; at this time, the clamping assembly 30 is driven by the moving assembly 50 and returns to the bottom of the second drum wheel 22 to perform the cigarette receiving operation.

[0094] The conveyor belt 60 provides a continuous and stable cigarette conveying platform, ensuring that the cigarettes can leave the punching process after being laser punched, thereby maintaining the continuous fluidity of the production line.

[0095] Example 2, specific operation of radial punching of cigarettes: the first drum wheel 21 takes the cigarettes out of the sorting channel 83, and then transfers the taken-out cigarettes to the second drum wheel 22, and clamps the cigarettes through the clamping assembly 30; driven by the moving assembly 50, the cigarette is moved to the front of the focusing head 73, and at the same time moves along the axial direction of the cigarette, so that the cigarette is located at a set position (the set position is the preparation position before punching); the cigarette is driven to rotate along its axis by the rotating assembly 40, and during the process of the cigarette rotating along the axis, the laser 71 is driven to generate laser pulses, and a single row or multiple rows of micropores are evenly burned on the circumferential surface of the cigarette filter. After the cigarette is punched, the cigarette is conveyed to the conveyor belt 60.

[0096] Example 3, specific operation of axial punching of cigarettes: the first drum wheel 21 takes the cigarettes out of the sorting channel 83, and then transfers the taken-out cigarettes to the second drum wheel 22, and clamps the cigarettes through the clamping assembly 30; driven by the moving assembly 50, the cigarettes are moved to the front of the focusing head 73, and at the same time moved along the axial direction of the cigarettes, so that the cigarettes are located at the set position; the moving assembly 50 drives the cigarettes to move at a uniform speed along their axial direction, and during the uniform movement of the cigarettes, the laser 71 is driven to generate laser pulses, and microholes are uniformly burned in a straight line along the axial direction of the cigarettes. After the punching of the cigarettes is completed, the cigarettes are conveyed to the conveyor belt 60.

[0097] Example 4, specific operation of punching holes in a cigarette at any oblique angle: adjust the setting angle of the optical path through the galvanometer group 72 and the focusing head 73, so that the optical path deviates from the central focusing point of the focusing head 73, so that it has a certain angle with the surface of the cigarette, and the laser is irradiated obliquely and focused on the surface of the cigarette. The drum group takes out the cigarette and transfers it to the clamping assembly 30, and the cigarette is moved to the front of the focusing head 73 through the moving assembly 50. The cigarette is driven by the rotating assembly 40 to rotate along the axis. During the rotation of the cigarette, the laser 71 is driven to generate laser pulses to evenly burn a single row or multiple rows of oblique micropores on the circumferential surface of the cigarette filter. After the cigarette is punched, it is transported to the conveyor belt 60.

[0098] Example 5, specific operation of spiral punching of cigarettes: the first drum wheel 21 takes the cigarettes out of the sorting channel 83, and then transfers the taken-out cigarettes to the second drum wheel 22, and clamps the cigarettes through the clamping assembly 30; driven by the moving assembly 50, the cigarettes are moved to the front of the focusing head 73, and at the same time moved along the axial direction of the cigarettes, so that the cigarettes are located at the set position; at this time, the rotating assembly 40 does not rotate, and when the laser 71 is driven to generate a laser pulse, at the same time, the moving assembly 50 drives the entire rotating assembly 40 and the cigarettes to move at a uniform speed along the axial direction of the cigarettes, and the rotating assembly 40 drives the cigarettes to rotate along their axis; during the uniform motion of the cigarettes, spirally distributed micropores are evenly burned on the circumferential surface of the cigarettes, and after the cigarettes are punched, they are conveyed to the conveyor belt 60.
