[0042] Embodiment 1: Figure 1 and Figure 2 As shown, a cigarette laser punching device includes an electric control cabinet 1, a laser 2, a plurality of optical lenses 3, a beam splitter 4, a bracket 5, a punching wheel 6 and a cigarette wheel 7; the electric control cabinet 1 can be installed near the laser and connected to the laser 2 through a cable to control and monitor the operating status of the laser. The laser 2 can be a CO2 laser, and the laser is usually installed on a stable workbench to ensure its stability during operation. It can be fixed by a bracket or a special mounting seat. The optical lens is usually installed on the optical path of the laser through a special fixture or bracket to ensure that the laser beam can accurately pass through each lens. The multiple optical lenses 3 are arranged on the optical path of the laser 2. The optical lens 2 is used to guide the laser to the light inlet of the beam splitter 4. The optical lens is usually installed on the optical path of the laser through a special fixture or bracket to ensure that the laser beam can accurately pass through each lens.

[0043] The beam splitter 4 is arranged on the bracket 5, and the beam splitter 4 is usually fixed to the bracket 5 by bolts or welding. The punching wheel 6 is located below the bracket 5, and the light outlet of the beam splitter 4 faces the punching station on the punching wheel 6. The punching wheel is usually installed below the bracket through bearings and motors to ensure that it can rotate stably. For example, the punching wheel can be driven by a motor to achieve automatic rotation, and the cigarette moving wheel 7 is arranged on both sides of the beam splitter 4, and the cigarette moving wheel 7 is used to move the cigarettes on the punching station. The cigarette moving wheel is usually installed on both sides of the beam splitter, and is driven to rotate by a motor or a pneumatic device.

[0044] The multiple optical lenses 3 include a first reflective lens 31, a second reflective lens 32, a third reflective lens 33 and a lens 34; the first reflective lens 31 is arranged on the optical path of the laser beam emitted by the laser 2, the second reflective lens 32 is arranged parallel to the first reflective lens 31, the third reflective lens 33 is arranged on the optical path of the laser beam reflected by the second reflective lens 32, the lens 34 is arranged on the optical path of the laser beam reflected by the third reflective lens 33, and the lens 34 is used to guide the laser to the light inlet of the beam splitter 4.

[0045] In this embodiment, the electric control cabinet 1 starts and controls the laser 2 to start working and emit a laser beam. The laser beam emitted by the laser 2 first irradiates the first reflective lens 31. The first reflective lens 31 reflects the laser beam to the second reflective lens 32. Since the second reflective lens 32 is arranged parallel to the first reflective lens 31, the direction of the laser beam changes after the second reflection. The reflected laser beam irradiates the third reflective lens 33. The third reflective lens 33 reflects the laser beam again so that it continues to propagate along the predetermined optical path. The laser beam reflected by the third reflective lens 33 is then irradiated onto the lens 34. The function of the lens 34 is to focus and guide the laser beam so that it can accurately irradiate the light inlet of the beam splitter 4. After receiving the laser beam, the beam splitter 4 divides it into multiple small laser beams, and each laser beam is irradiated to different punching stations on the punching wheel 6. The punching wheel 6 rotates stably under the drive of the motor. When the cigarette is transported to the punching station, the laser beam emitted by the beam splitter 4 will perform a punching operation on the cigarette. The design of the punching wheel 6 enables the cigarette to maintain a stable position and posture during the punching process, ensuring the accuracy and consistency of the punching. At the same time, the cigarette moving wheel 7 also rotates under the drive of the motor to move the cigarettes on the punching station.

[0046] Embodiment 2: Figure 3 As shown, considering that cigarettes of different specifications require different sizes of holes, in order to facilitate the adjustment of the size of the holes, the beam splitter 4 includes a housing 41, a light emitting member 42 and an adjustment component 43, as shown in FIG. Figure 4 As shown, a focusing lens 421 is provided in the light emitting member 42. The focusing lens 421 is used to focus the laser beam to make its energy more concentrated, so as to improve the efficiency and accuracy of punching. By adjusting the position of the focusing lens 421, the focus size of the laser beam can be adjusted to meet the punching requirements of cigarettes of different specifications.

[0047] like Figure 4 and Figure 5 As shown, the light emitting member 42 is disposed in the housing 41; a focusing lens 421 is disposed in the light emitting member 42, and the focusing lens 421 is slidably connected to the light emitting member 42. For example, a slide groove is provided on the inner wall of the light emitting member 42, and a slider is fixedly connected to the edge of the focusing lens 421, and the slider can slide up and down in the slide groove.

[0048] The adjusting component 43 is connected to the focusing lens 421, and the adjusting component 43 is used to drive the focusing lens 421 to slide up and down in the light emitting member 42. Figure 4 and Figure 5As shown, the adjustment component 43 includes: a connecting member 431 , which is connected to the focusing lens 421 ; an elastic member 432 , which is connected to the connecting member 431 ; and a limiting member 433 , which is in contact with the connecting member 431 .

[0049] For reference, the connecting member 431 can be a rigid component in a rod, bar or other suitable shape, which is directly connected to the focusing lens 421 for transmitting motion and force. The connecting member can be made of metal (such as stainless steel, aluminum, etc.), plastic or other suitable materials to ensure its strength and durability. The elastic member 432 is usually a spring for providing elasticity and reset function during the adjustment process. The spring can be located in the first accommodating cavity 411, with one end connected to the connecting member 431 and the other end connected to the bottom of the first accommodating cavity 411. The material of the spring can be metal, rubber or other elastic material.

[0050] like Figure 4 and Figure 5 As shown, a through groove 422 is provided on the side wall of the light emitting member 42; a first accommodating cavity 411 and a second accommodating cavity 412 are provided in the shell 41; the first accommodating cavity 411 is communicated with the through groove 422, one end of the second accommodating cavity 412 is communicated with the first accommodating cavity 411, and the other end of the second accommodating cavity 412 is communicated with the outside; the connecting member 431 is located in the through groove 422 and the first accommodating cavity 411; the elastic member 432 is located in the first accommodating cavity 411, one end of the elastic member 432 is connected to the connecting member 431, and the other end of the elastic member 432 is connected to the bottom of the first accommodating cavity 411; the limiting member 433 is threadedly connected to the second accommodating cavity 412.

[0051] like Figure 4 As shown, the limiting member 433 includes: a threaded portion 4331 and an abutting portion 4332, one end of the threaded portion 4331 is connected to one end of the abutting portion 4332, and the threaded portion 4331 is threadedly connected to the second accommodating cavity 412; the other end of the abutting portion 4332 abuts against the connecting member 431, and the cross-sectional area of ​​the abutting portion 4332 gradually decreases along the direction toward the connecting member 431.

[0052] For reference, the threaded portion 4331 is a cylindrical or similarly shaped portion with an external thread, which is used to match the internal thread of the second accommodating chamber 412. The abutting portion 4332 is a cone. Therefore, when the limit member 433 is screwed in toward the connecting member 431, the limit member 433 is in a first state, and the abutting area between the limit member 433 and the connecting member 431 gradually increases, the limit member 433 drives the connecting member 431 to descend, and the elastic member 432 is compressed; when the limit member 433 is screwed out toward the direction away from the connecting member 431, the limit member 433 is in a second state, and the abutting area between the limit member 433 and the connecting member 431 gradually decreases, and the elastic member 432 drives the connecting member 431 to rise.

[0053] Specifically, when the stopper 433 is screwed in toward the connecting member 431, the contact area between the contact part 4332 and the connecting member 431 gradually increases because the contact part 4332 is a cone, which will push the connecting member 431 to move downward. When the connecting member 431 moves downward, it will compress the elastic member 432 and drive the focusing lens 421 to slide downward in the light output member 42. Due to the movement of the focusing lens 421, the focus of the laser beam will become smaller, which is suitable for punching holes in smaller-sized cigarettes. On the contrary, if the stopper 433 is screwed out in a direction away from the connecting member 431, the contact area between the contact part 4332 and the connecting member 431 gradually decreases, and the elastic force of the elastic member 432 will push the connecting member 431 to move upward, thereby driving the focusing lens 421 to slide upward. This will make the focus of the laser beam larger, which is suitable for punching holes in larger-sized cigarettes.

[0054] For reference, the abutment portion 4332 can be a cone, and the tip of the cone abuts against the connecting member 431. When the limiting member 433 is screwed in toward the connecting member 431, the cone moves toward the connecting member 431, and the side wall of the cone gradually presses the connecting member 431 to move downward, while driving the focusing lens 421 to slide downward in the light output member 42. When the limiting member 433 is screwed out in the direction away from the connecting member 431, the cone moves in the direction away from the connecting member 431. Under the reaction of the elastic member 432, the connecting member 431 moves upward along the side wall of the abutment portion 4332, driving the focusing lens 421 to slide upward. It should be noted that when the cone moves in the direction away from the connecting member 431, the cone does not detach from the connecting member 431.

[0055] like Figure 4 and Figure 5 As shown, a support member 44 is provided on the outer wall of the shell 41, and a threaded ring 441 is provided on the support member 44. The threaded ring 441 is located on the outside of one end of the second accommodating cavity 412 that is connected to the outside; the other end of the threaded portion 4331 is threadedly connected to the threaded ring 441.

[0056] For reference, the support member 44 can be a fixing rod, one end of which is welded to the side wall of the shell 41, and a threaded ring 441 is welded on the fixing rod. The inner wall of the threaded ring 441 is provided with a thread matching the threaded portion 4331, and the threaded portion 4331 can be screwed in or out of the threaded ring 441. In addition, the threaded ring 441 on the support member 44 provides an additional support point for the limit member 433, so that the entire limit member 433 is more stable when being screwed in and out of the second accommodating cavity.

[0057] The light emitting members 42 are provided with two, and the adjustment components 43 are provided with two groups corresponding to the light emitting members 42 .

[0058] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
