Description

Technical Field

[0001] This application relates to the field of cigarette processing technology, and in particular to a laser-assisted detection device for the filter tip of a cigarette. Background Technology

[0002] Currently, during cigarette manufacturing, to improve ventilation during inhalation, reduce draw resistance, and increase combustion efficiency to reduce tar production, laser-drilled micro-holes are created at the filter tip. Laser perforation of cigarette filters has become a highly effective technique for reducing tar and harmful substances. This technology utilizes a high-energy laser to penetrate the cigarette tipping paper and filter rod forming paper to a certain depth, creating multiple micro-holes distributed along the circumference of the cigarette. During inhalation, these holes dilute the smoke, thus reducing tar and harmful substances.

[0003] However, in the actual production process of cigarettes, problems such as unstable laser drilling devices leading to cigarettes not being drilled or having poor drilling quality exist. Furthermore, there is a lack of necessary real-time online inspection equipment; currently, only random sampling by operators or individual inspection by drilling instruments is possible, which is inefficient, unable to detect based on relevant parameters, and results in poor inspection quality. This allows problematic cigarettes to flow into downstream equipment, ultimately creating production quality and safety hazards.

[0045] The following reference Figures 1 to 9 This application describes a laser-assisted detection device for the filter tip of a cigarette according to some embodiments.

[0046] See Figures 1 to 9 As shown, an embodiment of this application provides a laser-assisted detection device for the filter tip of a cigarette, comprising: a base 1 and an end limiting member 2, a first side limiting member 3, a second side limiting member 4, and an illumination member 5 disposed on the base 1; wherein, the base 1 is used to place multiple cigarettes 9 to be detected arranged side by side and in parallel; along a first preset direction a, the end limiting member 2 is disposed at one end of the base 1, and the end limiting member 2 is used to limit the same end of the multiple cigarettes 9 to be detected;

[0047] Along the second preset direction b, the first side limiting member 3 and the second side limiting member 4 are respectively arranged on opposite sides of the base 1, and are used to limit the two outermost sides of multiple并排且平行放置的待检测香烟9; the lighting member 5 is used to illuminate multiple待检测香烟9 to observe the distribution of laser holes on each待检测香烟9; a detection marking area 14 extending along the first preset direction a and the second preset direction b is formed on the upper surface of the base 1, and is used as a reference for detecting the positions of the laser holes on the待检测香烟9.

[0048] According to the structure described above, the use process of the cigarette filter tip laser hole auxiliary detection device provided by the present application is大致如下:

[0049] First, place multiple待检测香烟9并排且平行地 on the upper surface of the base 1, and make the same end of all待检测香烟9, that is, the non-filter tip end, simultaneously abut against the end limiting member 2, keeping this end of all待检测香烟9 flush, and make the first side limiting member 3 and the second side limiting member 4 respectively abut against the two outermost sides, that is, the left and right sides, of an entire row of待检测香烟9, playing a role in limiting the待检测香烟9 and preventing it from shifting during the detection process. Then, the lighting member 5 can be turned on to make the lighting member 5 illuminate the filter tip end, and manually拨动 the待检测香烟9 placed on the base 1, so as to facilitate observing the distribution of laser holes on the待检测香烟9, and comparing the distribution of the laser holes with the detection marking area 14. If the position of the laser hole falls within this detection marking area 14, it is considered qualified. If the position of the laser hole does not fall within this detection marking area 14, that is, outside the detection marking area 14, it is considered unqualified, and the defective products should be promptly picked out to facilitate the subsequent calculation of the defective product ratio. Of course, it is not limited to the above steps, and the above steps can also be adjusted according to actual needs.

[0050] It can be seen that the cigarette filter tip laser hole auxiliary detection device provided by the present application can quickly detect the positions of laser holes on a small batch of cigarettes, and the operation is simple, convenient, time-saving and labor-saving, greatly improving the detection efficiency. Moreover, the structure of this cigarette filter tip laser hole auxiliary detection device is simple and the cost is low.

[0051] Furthermore, preferably, the lighting member 5 is a round rod-shaped lamp, and it extends along the second preset direction b. Of course, it is not limited to this.

[0052] It should be noted that: along the height direction of the base 1, as long as the laser hole falls within the detection marking area 14 and the area directly above it, it belongs to qualified products, including falling on the edge lines on both sides of the detection marking area 14 along the first preset direction a, which also belongs to qualified products.

[0053] In this embodiment, preferably, as Figure 1 and It should be noted that the Chinese expressions "并排且平行放置的待检测香烟9" and "拨动" in the original text seem to be a bit unclear or incomplete in terms of accurate meaning. The translation is done as accurately as possible based on the context, but these parts might need further clarification in the original text for more precise translation. Figure 2 As shown, the laser hole auxiliary detection device for cigarette filter tip also includes a main detection mark 11, a first detection tolerance mark 12, and a second detection tolerance mark 13 formed on the upper surface of the base 1; wherein, the main detection mark 11, the first detection tolerance mark 12, and the second detection tolerance mark 13 are all arranged along a second preset direction b; along the first preset direction a, the first detection tolerance mark 12 and the second detection tolerance mark 13 are respectively spaced apart on opposite sides of the main detection mark 11, and the first detection tolerance mark 12 is arranged close to the end limiting member 2, and a detection mark area 14 is formed between the first detection tolerance mark 12 and the second detection tolerance mark 13.

[0054] As can be seen from the structure described above, by setting a main detection mark 11, a first detection tolerance mark 12, and a second detection tolerance mark 13 on the base 1, and with the first detection tolerance mark 12 and the second detection tolerance mark 13 respectively set on opposite sides of the main detection mark 11, a detection interval, namely the detection mark area 14, is formed between the first detection tolerance mark 12 and the second detection tolerance mark 13. Moreover, since the main detection mark 11 is set, it is also possible to know whether the laser hole on the cigarette falls in the positive tolerance area or the negative tolerance area relative to the main detection mark 11, which is also convenient for subsequent statistics.

[0055] In this embodiment, preferably, as follows: Figure 1 As shown, the main detection mark 11 is a groove formed on the base 1, and a reflective material (such as reflective powder, or, of course, not limited to, reflective strips) is provided inside the groove. When the light from the illumination component 5 shines on the reflective material, the reflective powder will emit light, making it easier to observe. Of course, it is not limited to this. When the main detection mark 11 is a groove structure, the reflective material may not be provided inside it. In addition, the structure of the main detection mark 11 is not limited to a groove. It may also be a marking line coated on the surface of the base 1. Preferably, this marking line may be designed to be a reflective material under the illumination of light, which also facilitates observation. Of course, it is not limited to this. The main detection mark 11 may also be designed according to actual needs.

[0056] In this embodiment, preferably, as follows: Figure 1As shown, the first inspection tolerance mark 12 is a groove formed on the base 1, and a reflective material (such as reflective powder, or, of course, not limited to, reflective strips) is provided inside the groove. When the light from the illumination component 5 shines on the reflective material, the reflective powder will emit light, making it easier to observe. Of course, it is not limited to this. When the first inspection tolerance mark 12 is a groove structure, the reflective material may not be provided inside it. In addition, the structure of the first inspection tolerance mark 12 is not limited to a groove. It may also be a marking line coated on the surface of the base 1. Preferably, this marking line may be designed to be made of a reflective material under the illumination of light, which also facilitates observation. Of course, it is not limited to this. The first inspection tolerance mark 12 may also be designed according to actual needs.

[0057] In this embodiment, preferably, as follows: Figure 3 As shown, 4. The distance between the centerline of the main detection mark 11 set along the second preset direction b and the end limiting member 2 along the first preset direction a is L1, and L1=97mm;

[0058] The distance between the centerline of the first inspection tolerance mark 12 set along the second preset direction b and the end limiting member 2 along the first preset direction a is L2, and L2 = 97 + 0.5 mm;

[0059] The distance between the centerline of the second inspection tolerance mark 13 set along the second preset direction b and the end limit member 2 along the first preset direction a is L3, and L3 = 97 - 0.5 mm.

[0060] As described above, along the first preset direction a, the distance between the main detection mark 11 and the end limiting member 2 is 97mm. Therefore, the tolerance of the laser hole reference line is 97±0.5mm, forming a detection area, namely the detection mark area 14. Using the detection mark area 14 as the detection reference better meets the actual detection requirements. Of course, the value of L1 is not limited to the above optimal value and can be selected according to data requirements. Furthermore, the tolerance of the laser hole reference line can also be selected according to actual needs.

[0061] In this embodiment, preferably, as follows: Figure 1As shown, the second inspection tolerance mark 13 is a groove formed on the base 1, and a reflective material (such as reflective powder, or, of course, not limited to, reflective strips) is provided inside the groove. When the light from the illumination component 5 shines on the reflective material, the reflective powder will emit light, making it easier to observe. Of course, it is not limited to this. When the second inspection tolerance mark 13 is a groove structure, the reflective material may not be provided inside it. In addition, the structure of the second inspection tolerance mark 13 is not limited to a groove. It may also be a marking line coated on the surface of the base 1. Preferably, this marking line may be designed to be made of a reflective material under the illumination of light, which also facilitates observation. Of course, it is not limited to this. The second inspection tolerance mark 13 may also be designed according to actual needs.

[0062] Furthermore, it should be noted that the structure of the detection marking area 14 provided in this application is not limited to the structure including the main detection mark 11, the first detection tolerance mark 12, and the second detection tolerance mark 13. Other structures can also be used. For example, a groove extending along the first preset direction a, the second preset direction b, and the height direction of the base 1 can be directly carved into the base 1. This groove is the detection marking area 14. Alternatively, a reflective material or colored area extending along the first preset direction a, the second preset direction b, and the height direction of the base 1 can be directly coated on the upper surface of the base 1 as the detection marking area 14. The specific choice depends on the actual needs.

[0063] In this embodiment, preferably, as follows: Figure 1 and Figure 2 As shown, the first side limiting member 3 is fixedly connected to the base 1; the second side limiting member 4 is slidably connected to the base 1; the laser hole auxiliary detection device at the cigarette filter end also includes a fastening member 6, such as a screw or bolt, and the fastening member 6 is used to fix the second side limiting member 4 on the base 1, and when the fastening member 6 releases its fixing effect on the second side limiting member 4, the second side limiting member 4 can slide relative to the base 1 along the second preset direction b.

[0064] As can be seen from the structure described above, this application designs the first side limiting member 3 to remain stationary, and the second side limiting member 4 to be movable. The second side limiting member 4 can be moved toward or away from the first side limiting member 3, thereby adjusting the width between the two, that is, adjusting the number of cigarettes placed, to meet the detection requirements of different numbers of cigarettes, thus having a wider range of applications. Moreover, after the spacing is adjusted, the second side limiting member 4 can be fixed by the fastening member 6 to prevent displacement and ensure its limiting effect on the cigarettes, which helps to improve the detection accuracy.

[0065] In this embodiment, preferably, as follows: Figures 4 to 7As shown, the base 1 has a groove 16 extending along the second preset direction b; the second side limiting member 4 includes a limiting part 41, a connecting part 42 and a mating part 43 connected in sequence, and the mating part 43 is slidably engaged with the groove 16. The connecting part 42 and the limiting part 41 are located outside the groove 16, and the limiting part 41 is used to limit the outermost side of multiple cigarettes 9 to be tested that are placed side by side and parallel.

[0066] As can be seen from the structure described above, a slide groove 16 is opened on the base 1, and the second side limiting member 4 is designed as a U-shaped structure, with the opening of the U-shaped structure facing the first side limiting member 3. The side wall of the bottom of the U-shaped structure, which is set along the horizontal direction, is movably inserted into the slide groove 16, thereby realizing a sliding connection. The limiting part 41 is located outside the slide groove 16 and can abut against the side of a row of cigarettes 9 to be tested, thus playing a limiting role.

[0067] In this embodiment, preferably, as follows: Figures 4 to 7 As shown, the second side limiting member 4 has a first mounting through hole 44 arranged along the second preset direction b, the base 1 has a second mounting through hole 15 arranged along the second preset direction b, and the fastening member 6, such as a screw or bolt, is installed in the first mounting through hole 44 and the second mounting through hole 15 along the second preset direction b, and the fastening member 6 is at least threadedly connected to the second mounting through hole 15.

[0068] As can be seen from the structure described above, when the second side limiting member 4 is moved to the appropriate position, it can be locked by fastening member 6, such as screw or bolt, to keep the adjusted position of the second side limiting member 4 still, thereby improving the detection accuracy and making the operation simple and convenient.

[0069] Of course, it is not limited to the above. The cooperation structure between the fastening member 6, the second side limiting member 4, and the base 1 can also be designed according to actual needs. For example, one of the second side limiting member 4 and the base 1 forms an oblong through hole along the second preset direction b, and the other forms a threaded hole along the height direction of the base 1 and the second side limiting member 4. The fastening member 6 is installed in the oblong through hole and the threaded hole along the height direction of the base 1 and the second side limiting member 4.

[0070] As can be seen, by setting the waist-shaped through hole, the locking position of the fastening component 6 can also be adjusted accordingly, thereby adapting to the adjustment of the position of the second side limiting component 4.

[0071] In this embodiment, preferably, as follows: Figure 1 and Figure 2As shown, the laser hole auxiliary detection device for cigarette filter tip also includes a converter component 7. Along the first preset direction a, the lighting component 5 is spaced apart at one end of the base 1 away from the end limiting member 2, and the lighting component 5 is connected to the damping rotation via the converter component 7.

[0072] As can be seen from the structure described above, the lighting component 5 is connected to the damping rotation via the adapter component 7, which makes it easy to select the position of the lighting component 5 according to actual needs, so as to meet the illumination requirements of different directions of the cigarette, and achieve the best observation effect on the laser hole position. It is more practical and has a wider range of applications.

[0073] In this embodiment, preferably, as follows: Figure 1 and Figure 2 As shown, when the lighting component 5 is connected to the base 1 in a damped rotatable manner via the adapter component 7, the laser hole auxiliary detection device at the cigarette filter tip also includes a first rotating shaft 71, a first sliding sleeve 72, a second sliding rod 73, and a second rotating shaft 74; wherein, the second sliding rod 73 is connected to the first sliding sleeve 72 in a damped slidable manner.

[0074] The first rotating shaft 71 is fixed to the base 1, and the end of the first sliding sleeve 72 is formed with a first mating ring 75, which is damped and rotatably connected to the first rotating shaft 71; the second rotating shaft 74 is fixed to the lighting component 5, and the end of the second sliding rod 73 is formed with a second mating ring 76, which is damped and rotatably connected to the second rotating shaft 74.

[0075] As can be seen from the structure described above, the second slide rod 73 and the first slide sleeve 72 are connected in a damped sliding connection. When the lighting component 5 is flipped, that is, when the position of the lighting component 5 is adjusted, the second slide rod 73 and the first slide sleeve 72 can adaptively adjust their relative positions along the length direction to meet the adjustment requirements without jamming. Moreover, since it is a damped sliding connection, it can remain stationary after the position is adjusted until the next adjustment, making the structure more stable and reliable. Furthermore, the end of the first slide sleeve 72 has a first mating ring 75, and the first mating ring 75 is connected in a damped rotation to the first rotating shaft 71. The end of the second slide rod 73 has a second mating ring 76, and the second mating ring 76 is connected in a damped rotation to the second rotating shaft 74. When the lighting component 5 is flipped, there will be no jamming or other problems.

[0076] It should be noted that the lighting component 5 is not limited to a damped rotatable connection with the base 1; the two can also be fixedly connected. For example, the laser hole auxiliary detection device at the cigarette filter end also includes a connecting component. Along the first preset direction a, the lighting components 5 are spaced apart at the end of the base 1 away from the end limiting member 2, and the lighting components 5 are fixedly connected to the base 1 through the connecting component. Therefore, after finding the optimal lighting position of the lighting component 5 through multiple experiments, the lighting component 5 can be fixed to the base 1 at this position and kept stationary, which can also meet the usage requirements.

[0077] In this embodiment, preferably, as follows: Figure 1 and Figure 2 As shown, the laser hole auxiliary detection device for cigarette filter tip also includes multiple detection sleeves 8 of different specifications, and the inner diameter of the multiple detection sleeves 8 is different; the base 1 has multiple mounting holes, and the multiple detection sleeves 8 of different specifications are installed in different mounting holes.

[0078] As can be seen from the structure described above, several mounting holes of different diameters are also provided on the end limiting member 2. Each mounting hole is equipped with a detection sleeve 8 of a certain specification, so that cigarettes of different diameters can be detected, thereby improving the quality of the product. It can be seen that the laser hole auxiliary detection device for cigarette filter end provided in this application has more functions.

[0079] Furthermore, preferably, the edge of the specification testing sleeve 8 is provided with a limiting flange, and the limiting flange abuts against the top of the end limiting member 2.

[0080] Furthermore, preferably, the specification testing sleeve 8 is adapted to or clearance-fitted with the mounting hole, which facilitates installation and disassembly.

[0081] It should be noted that when using the aforementioned specification testing sleeve 8 to test the diameter of a cigarette, the cigarette can be inserted into the specification testing sleeve 8 of the corresponding size.
