[0002] In the current development of the cigarette industry, to meet the ever-increasing market demands, a series of new processes and technologies, such as heated tobacco products and composite processes, have emerged and are gradually being widely applied to cigarette products. The application of these innovative technologies has, to a certain extent, injected new vitality into cigarette products and satisfied the diverse needs of consumers.
[0003] However, with the promotion of new processes and technologies, many thorny problems have also arisen. Some processes operate inside the cigarette, such as tobacco sorting and reverse sizing, but conventional testing methods cannot detect the internal quality of the cigarette, making it difficult to effectively control the quality of the internal processes. This leads to a predicament of low quality control accuracy for some cigarette products when internal process quality testing is required, greatly increasing the risk of substandard cigarette products flowing into downstream processes and posing a serious threat to the overall product quality and the stability of the production process.
[0004] At the same time, there are compatibility issues between new processes and technologies and existing cigarette platforms, and the products produced by different cigarette factories vary, which further exacerbates the difficulty of technology integration and makes it difficult to add internal cigarette detection functions to existing equipment.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0043] like Figures 1 to 7As shown, this embodiment provides a cigarette cutting device, including a base 1, a radial limiting component 2, an axial limiting component 3, and a cutting component 4. The base 1 can be detachably connected to the cigarette rolling equipment. The radial limiting component 2 includes a limiting seat 21 and a pressing member 22. The limiting seat 21 is disposed on the base 1, and a limiting cavity 211 adapted to the shape of the cigarette 100 is opened in the limiting seat 21. The limiting cavity 211 is used to accommodate the cigarette 100. A radially penetrating positioning groove 212 is opened on the side wall of the limiting cavity 211. The pressing member 22 can radially abut against the cigarette 100 through the positioning groove 212, thereby pressing and fixing the cigarette 100. The limiting component 3 includes a limiting member 31, which is inserted into one end of the limiting cavity 211 and is used to axially abut against the cigarette 100, thereby achieving axial positioning of the cigarette 100. The cutting component 4 includes a mounting base 41 and a cutting blade 42. The mounting base 41 is slidably connected to the base 1 in a direction parallel to the axis of the limiting cavity 211. The cutting blade 42 is mounted on the mounting base 41. The limiting base 21 also has a cutting groove 213 extending in a direction parallel to the axis of the limiting cavity 211. The cutting groove 213 communicates with the limiting cavity 211. The cutting blade 42 can cut the cigarette 100 in the limiting cavity 211 through the cutting groove 213.
[0044] When it is necessary to cut the cigarette 100, the cigarette 100 is first inserted into the limiting cavity 211 from the end away from the limiting member 31. When the cigarette 100 axially abuts against the limiting member 31, the pressing member 22 penetrates into the positioning groove 212 and radially abuts against the cigarette 100, pressing and fixing the cigarette 100 in the limiting cavity 211. Then, the cutting blade 42 is driven to slide in a direction parallel to the axis of the limiting cavity 211, thereby cutting the cigarette 100. By using the above-mentioned cutting device, the cigarette 100 can be easily fixed, thereby cutting the cigarette 100 to facilitate the detection of the internal quality of the cigarette 100, thereby improving the quality control accuracy of cigarette 100 products, reducing the risk of unqualified cigarette 100 products entering downstream processes, and can be detachably connected to the cigarette rolling equipment through the base 1, which can be adapted to different cigarette rolling equipment, realizing the integration of the internal quality detection device of the cigarette 100 on existing equipment.
[0045] like Figure 2 As shown, the base 1 has a first mounting hole 11, and the cigarette cutting device also includes a fastener. The fastener can be threadedly connected to the cigarette rolling equipment through the first mounting hole 11, thereby fixing the base 1 at any horizontal position of the equipment, so that the staff can promptly inspect the cigarette 100.
[0046] Furthermore, to facilitate the sampling inspection of cigarette sticks 100 by staff, a first magnetic component 5 is provided on the base 1. The base 1 is magnetically connected to the cigarette rolling equipment through the first magnetic component 5. Staff can easily attach the cutting device to the cigarette rolling equipment and change the attachment position at any time to facilitate the sampling inspection of cigarette sticks 100 in different positions, which greatly improves the convenience of inspection.
[0047] like Figures 3-5 As shown, in this embodiment, the radial limiting component 2 further includes a locking handle 23 and an elastic element 24. The pressing member 22 has a first locking hole, and the limiting seat 21 has a corresponding second locking hole. The locking handle 23 passes through the first locking hole, and one end of the locking handle 23 is threadedly connected to the second locking hole. The other end is used to press and fix the pressing member 22 onto the limiting seat 21 so that the pressing member 22 radially abuts against the cigarette 100 in the limiting cavity 211. The elastic element 24 is pre-compressed between the pressing member 22 and the limiting seat 21. The elastic restoring force of the elastic element 24 can balance the pressure of the pressing member 22 on the cigarette 100 and prevent the cigarette 100 from being deformed due to excessive force. The locking handle 23 provides reliable fixation for the cigarette 100. By clamping the cigarette 100 with the clamping member 22, both radial rotation and axial displacement of the cigarette 100 can be prevented. Moreover, the locking handle 23 is easy to operate, allowing the operator to easily turn the handle to fix the cigarette 100 or release the cut cigarette 100, further improving the convenience of operation.
[0048] It is easy to understand that, in order to facilitate the insertion of the cigarette 100 into the limiting cavity 211, the limiting cavity 211 is adapted to the shape of the cigarette 100, and the diameter of the limiting cavity 211 is 0.05mm to 1.5mm larger than the diameter of the cigarette 100, so that the cigarette 100 can smoothly enter the limiting cavity 211. The cooperation between the clamping member 22 and the limiting cavity 211 together achieves the fixation of the cigarette 100. The diameter of the limiting cavity 211 can be, but is not limited to, 0.05mm, 0.2mm, 1mm or 1.5mm larger than the diameter of the cigarette 100.
[0049] Furthermore, the contact surface between the clamping member 22 and the cigarette 100 is adapted to the shape of the cigarette 100, and together with the inner wall of the limiting cavity 211, it clamps the cigarette 100, which can increase the contact area between the clamping member 22 and the cigarette 100, better fix the cigarette 100, and prevent the clamping member 22 from crushing the cigarette 100.
[0050] like Figure 5As shown, further, an installation opening 214 communicating with the positioning groove 212 is formed in the limiting seat 21 for accommodating the limiting member 31 and the pressing member 22, and the second locking hole is formed at the bottom of the installation opening 214. The installation opening 214 provides an accurate installation position for the pressing member 22, which is beneficial to improving the installation efficiency and the connection stability between components, and makes the radial limiting component 2 compact in structure and smooth in appearance, facilitating installation and storage.
[0051] Continuing as Figure 3 And as Figure 4 As shown, the limiting member 31 is axially adjustably connected to the base 1 along the axial direction of the limiting cavity 211. The staff can adaptively adjust the length of the limiting member 31 extending into the limiting cavity 211 according to the length of the cigarette rod 100, so as to achieve the axial positioning of cigarette rods 100 with different lengths, improving the versatility of the cigarette cutting device and the sliding connection.
[0052] Specifically, the axial limiting component 3 further includes a first guide rail 32, a first locking member 33 and an installation block 34. The limiting member 31 is installed on the installation block 34. The first guide rail 32 extends along the direction parallel to the axis of the limiting cavity 211. The installation block 34 is provided with a first guiding groove slidably matched with the first guide rail 32. The first locking member 33 is connected to the installation block 34 and can be abutted against the first guide rail 32. When the staff slides the installation block 34 according to the length of the cigarette rod 100 to complete the adjustment of the position of the limiting member 31, the installation block 34 can be locked and fixed on the first guide rail 32 through the first locking member 33.
[0053] Among them, the limiting member 31 includes a connecting portion 311 and an abutting portion 312. One end of the connecting portion 311 is connected to the installation block 34, and the other end is connected to the abutting portion 312. The radius of the abutting portion 312 is denoted as a, the radius of the cigarette rod 100 is denoted as b, and the preset cutting depth is denoted as c. Then a < b - c, so as to avoid the interference between the limiting member 31 and the cutting knife 42, effectively avoid the friction between the cutting knife 42 and the limiting member 31, and improve the service life of the cutting knife 42.
[0054] As Figure 1 、 Figure 6 And Figure 7 As shown, the cutting component 4 further includes a second guide rail 43 extending along the direction parallel to the axis of the limiting cavity 211. The mounting seat 41 is provided with a second guiding groove 411 slidably matched with the second guide rail 43, so as to provide guidance for the sliding of the mounting seat 41 along the direction parallel to the axis of the limiting cavity 211, greatly improving the accuracy of the sliding process of the mounting seat 41. During the cutting operation, this enables the mounting seat 41 to move stably along the preset trajectory, avoiding deviation or shaking, thus effectively ensuring the accuracy and consistency of the cutting operation and significantly improving the cutting quality.
[0055] Furthermore, a third guide groove 431 extending parallel to the axis of the limiting cavity 211 is provided on the second guide rail 43. The cutting assembly 4 also includes a guide member 44, which is mounted on the mounting base 41 and slidably connected to the third guide groove 431, further enhancing the guiding effect. This multi-guide design can distribute the force during the sliding process, reduce the pressure on a single guide structure, thereby reducing the wear of the second guide rail 43, the second guide groove 411, and the guide member 44, extending the service life of each component, and reducing the maintenance cost and frequency of the equipment. It also greatly enhances the stability of the entire cutting assembly 4 during operation, ensuring that the mounting base 41 remains stable during movement, effectively reducing displacement deviations caused by vibration or external interference, and ensuring that the cutting blade can remain in the optimal position when cutting the cigarette stick 100. This effectively guarantees the stability and reliability of the cutting process, enabling the equipment to better adapt to the needs of continuous and efficient cutting operations under different working conditions.
[0056] The third guide groove 431 is closed at both ends along its length and can abut against the guide member 44, which limits the movement of the mounting base 41 and helps to ensure operational safety.
[0057] Specifically, the mounting base 41 has a second mounting hole that runs vertically through it. The guide member 44 is inserted into the second mounting hole. The cutting assembly 4 also includes a third locking member 46. The third locking member 46 can pass through the side wall of the second mounting hole and abut against the guide member 44 to lock and fix the guide member 44.
[0058] Furthermore, each end of the second guide rail 43 is provided with a second magnetic element 6. The second magnetic element 6 is used to attract the mounting base 41. When the mounting base 41 moves to both ends of the second guide rail 43, the magnetic attraction of the first magnetic element 5 to the mounting base 41 can produce a deceleration effect on the mounting base 41, effectively preventing the safety hazards caused by the cutting blade 42 to the human body and improving safety performance.
[0059] like Figure 1 and Figure 6 As shown, the mounting base 41 has a mounting groove 412. The axis of the mounting groove 412 is set at an angle to the axis of the limiting cavity 211. The handle 421 of the cutting blade 42 is inserted into the mounting groove 412. The cutting assembly 4 also includes a second locking member 45. The second locking member 45 can pass through the side wall of the mounting groove 412 and abut against the handle 421. The operator can adjust the position of the handle 421 in the mounting groove 412 to adjust the depth of the cutting head 422 of the cutting blade 42 into the limiting cavity 211, thereby adjusting the cutting depth according to the testing requirements. The second locking member 45 can easily lock or unlock the handle 421. It is easy to operate and the connection is stable.
[0060] Furthermore, the direction in which the limiting cavity 211 extends from the end with the limiting member 31 to the other end is designated as the first direction, and the mounting groove 412 gradually tilts towards the limiting seat 21 along the first direction. It is easy to understand that, in order to prevent the cigarette 100 from shifting, during cutting, the operator cuts from the end furthest from the limiting member 31 towards the end closest to the limiting member 31. This arrangement causes the cutting blade 42 to gradually tilt away from the limiting member 31 from the end furthest from the limiting member 31 towards the end closest to the limiting member 31, resulting in a reasonable structural design that facilitates operation. Furthermore, it ensures that the angle between the cutting edge of the cutting blade 42 and the cigarette 100 is acute, which is beneficial for operational safety.
[0061] like Figure 7 As shown, the handle 421 is provided with a protrusion 423, which can improve the grip experience of the operator and facilitate the cutting operation.
[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
