[0025] This utility model provides a technical solution:

[0026] Please see Figures 1-4 A device for inspecting the laser perforation of cigarettes includes a base 1 and a bracket 2 fixedly installed on the base 1. An illumination lamp 3 is provided on the bracket 2, and a cigarette detection structure 4 is provided at the bottom of the illumination lamp 3.

[0027] The cigarette detection structure 4 includes a focusing tube 401. A positioning step 402 is fixedly installed on the inner circular surface of the focusing tube 401. A cigarette placement groove 403 is provided on the focusing tube 401. A cigarette positioning blocking block 404 is fixedly installed on the side of the cigarette placement groove 403 near the inner circular surface of the focusing tube 401. An arc-shaped limiting block 405 is fixedly installed on the side of the cigarette placement groove 403 near the outer circular surface of the focusing tube 401.

[0028] The cigarette body 406 is inserted into the cigarette placement groove 403. The cigarette positioning blocking block 404 and the arc-shaped limiting block 405 work together to restrict the position of the cigarette and prevent shaking. At the same time, the positioning step 402 of the focusing tube 401 assists in fixing the illumination lamp 3. The light from the illumination lamp 3 is concentrated by the focusing tube 401 and reflected onto the cigarette by the reflector component 5, so that the laser pinhole forms a clear light spot, which is convenient for intuitive observation of the number and distribution of pinholes, improving detection efficiency and accuracy, while protecting the operator's eyesight.

[0029] Please see Figures 2-4 The inner cavity of the cigarette holder groove 403 is provided with a cigarette body 406; the focusing tube 401 is symmetrically provided with threaded holes 407, and the inner cavity of the threaded hole 407 is threadedly connected with a threaded rod 408.

[0030] The cigarette is placed in the cigarette placement groove 403, which is designed to secure the cigarette by having one end larger than the cigarette's diameter and the other end smaller than the cigarette's diameter. By rotating the threaded rod 408, its end is brought into close contact with both sides of the illumination lamp 3, thus achieving a stable connection between the focusing tube 401 and the illumination lamp 3. This ensures stable positioning and concentrated light during cigarette testing, improving testing efficiency and accuracy.

[0031] Preferably, the positioning step 402 is fixedly installed in the middle of the focusing tube 401. The positioning step 402 is circular in shape, and the inner diameter of the positioning step 402 is smaller than the inner diameter of the focusing tube 401.

[0032] In this embodiment, when installing the cigarette detection structure 4, the positioning step serves as a fixed component in the middle of the focusing tube. Its annular structure is compatible with the illumination lamp. Setting the inner diameter of the positioning step 402 to be smaller than the inner diameter of the focusing tube 401 makes the cigarette detection structure 4 more firmly fixed.

[0033] Preferably, the cigarette placement groove 403 is connected to the inner cavity of the focusing tube 401, wherein one end of the cigarette placement groove 403 is larger than the diameter of the cigarette body 406, and the other end of the cigarette placement groove 403 is smaller than the diameter of the cigarette body 406.

[0034] In this embodiment, the cigarette is inserted from the wider end of the cigarette placement groove 403. The groove 403 is wider than the diameter of the cigarette body 406 for easy insertion, while the other end is narrower to form a locking mechanism to secure the cigarette and prevent it from shaking or falling. This ensures the cigarette remains stable during the testing process, allowing the light emitted by the illumination lamp 3 to accurately pass through the laser holes on the cigarette, forming a clear light spot. This allows operators to visually observe the number and distribution of the holes, improving testing efficiency and accuracy, while avoiding the inefficiency and complexity of traditional testing methods.

[0035] Preferably, the focusing tube 401 is adapted to the illumination lamp 3, and the focusing tube 401 and the illumination lamp 3 are connected by compression through a threaded rod 408.

[0036] In this embodiment, the threaded rod 408 is rotated so that its end is in close contact with both sides of the illumination lamp 3. The squeezing action of the threaded rod 408, combined with the positioning step 402 on the inner circular surface of the focusing tube 401, achieves a stable connection between the focusing tube 401 and the illumination lamp 3.

[0037] Preferably, a pad adapted to the threaded rod 408 is fixedly installed at one end of the threaded rod 408 near the illumination lamp 3, wherein the pad is made of rubber material.

[0038] In this embodiment, when fixing the focusing tube 401 and the illumination lamp 3, the operator rotates the threaded rod 408 so that its end is close to the illumination lamp 3. At this time, the rubber pad at one end of the threaded rod 408 contacts the illumination lamp 3. Through the elastic cushioning of the rubber pad, the threaded rod 408 is ensured to tightly and securely connect the focusing tube 401 and the illumination lamp 3, while avoiding damage to the illumination lamp. The rubber pad not only enhances the stability of the connection, but also protects the illumination lamp from damage due to excessive compression, ensuring the long-term stable operation of the device.

[0039] Preferably, a lamp mounting housing is fixedly installed on the bracket 2, wherein the lamp 3 is fixedly installed on the lamp mounting housing.

[0040] In this embodiment, the illumination lamp mounting sleeve securely mounts the illumination lamp 3, ensuring that the position of the illumination lamp 3 is fixed and the light direction is accurate. This provides a stable and reliable mounting platform for the illumination lamp 3, ensuring that the illumination lamp 3 will not shift or shake during operation, thereby ensuring that the light can accurately and centrally illuminate the cigarette detection structure 4.

[0041] Please see Figure 2 and Figure 4 The inner cavity bottom of the focusing tube 401 is provided with a reflective component 5. The reflective component 5 includes a mounting ring 501 fixedly installed on the inner cavity bottom of the focusing tube 401, and a reflector 502 is fixedly installed on the mounting ring 501.

[0042] The reflector 502 can reflect and concentrate light onto the cigarette body 406, making the laser pinholes form clear light spots. This allows operators to visually observe the number and distribution of laser pinholes on the cigarette, thereby effectively improving detection efficiency and accuracy. At the same time, it avoids direct light shining into the operator's eyes, protecting their visual health.

[0043] Preferably, the reflector 502 is adapted to the mounting ring 501, wherein the reflective surface of the reflector 502 faces the position of the cigarette placement groove 403.

[0044] In this embodiment, the reflective surface of the reflector 502 is positioned facing the cigarette placement groove 403, so that the reflector 502 can effectively reflect and concentrate the light onto the cigarette body 406, making the laser pinholes form clearly visible light spots. This allows operators to intuitively observe the number and distribution of laser pinholes on the cigarette, thereby greatly improving detection efficiency and accuracy.

[0045] Preferably, the bracket 2 is in the shape of a right angle, and a diagonal reinforcing rod is fixedly installed at the right angle of the bracket.

[0046] In this embodiment, the bracket 2 is stably supported on the base with its right-angled structure, and a diagonal reinforcing rod is fixedly installed at the right-angled angle to enhance the stability and load-bearing capacity of the bracket, ensuring that the illumination lamp and cigarette detection structure remain stable during the detection process. The diagonal reinforcing rod provides additional support, effectively preventing the bracket from deforming or shaking during long-term use or under external force, thus ensuring the overall stability and detection accuracy of the detection device.

[0047] When using this device to inspect the laser perforation of cigarettes, the cigarette detection structure 4 must first be installed. The operator rotates the threaded rod 408 so that its end is tightly against both sides of the illumination lamp 3. The squeezing action of the threaded rod 408, combined with the precise positioning of the positioning step 402, ensures that the cigarette detection structure 4 can be firmly fixed in the predetermined position, providing a solid foundation for subsequent inspection work.

[0048] Subsequently, the cigarette body 406 to be tested is accurately inserted into the cigarette placement groove 403. A cigarette positioning blocking block 404 is fixedly installed on the side of the cigarette placement groove 403 near the inner circular surface of the focusing tube 401, while an arc-shaped limiting block 405 is provided on the side near the outer circular surface of the focusing tube 401. These two work together to precisely limit the position of the cigarette body 406, preventing it from shaking during the testing process. At the same time, one end of the cigarette placement groove 403 is designed to be slightly larger than the diameter of the cigarette body 406 to facilitate the insertion of the cigarette; while the other end is slightly smaller than the diameter of the cigarette body 406 (for example, one end is 0.4 mm smaller than the diameter of the cigarette body 406, and the other end is 0.2 mm larger than the diameter of the cigarette body 406). This design can effectively prevent the cigarette from shaking and accidentally falling off the cigarette placement groove 403, ensuring the smooth progress of the testing process.

[0049] After the cigarette is securely placed, the illumination lamp 3 can be activated. The light emitted by the illumination lamp 3 first shines on the reflector 502 at the bottom of the inner cavity of the focusing tube 401. The reflector 502 uses the principle of light refraction to reflect the light to the cigarette placement groove 403, so that the light can be concentrated onto the cigarette body 406. At this time, the light will pass through the laser pinholes on the cigarette body 406, forming clear light spots, which directly correspond to the laser pinholes on the cigarette. By manually rotating the cigarette body 406, the operator can more comprehensively observe the number and distribution of laser pinholes on the cigarette body 406, greatly improving the comprehensiveness and accuracy of the detection.

[0050] Meanwhile, due to the design of the cigarette holder groove 403, the reflected light from the reflector 502 will not directly shine into the operator's eyes. This not only protects the operator's visual health but also makes daily use more convenient and safer.

[0051] To comprehensively and meticulously inspect the laser-drilled holes on cigarettes, operators can slowly rotate the cigarette body 406 and repeatedly observe the changes in the laser-drilled holes. By carefully observing the shape, size, number, and distribution of the laser spots, operators can intuitively determine whether the laser-drilled holes on the cigarette meet quality requirements. For example, they can check whether the shape of the laser spots is regular, whether the number of laser spots matches the preset number of holes, and whether the distribution of the laser spots is uniform. This inspection method not only significantly improves inspection efficiency but also makes the inspection results more intuitive and accurate through direct observation of the laser spots, effectively avoiding inspection errors caused by human factors in traditional inspection methods, and providing reliable technical support for cigarette quality control.

[0052] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
