Description

Technical Field

[0001] This utility model relates to the field of cigarette detection technology, and in particular to an automatic marking device for the end position of cigarette combustion. Background Technology

[0002] In the quality control process of cigarette production, the detection of key chemical indicators of cigarette combustion (such as nicotine and tar) relies on the precise simulation of the combustion process by a smoking machine in the laboratory. Specifically, the smoking machine captures particulate matter produced during combustion by controlling the combustion termination point of the cigarette and analyzes its chemical composition. Among these, the positioning accuracy of the combustion termination point directly affects the amount of particulate matter captured and the accuracy of subsequent test results, and is a key technical link that determines the reliability of the test data.

[0003] Currently, laboratories typically use a soft-tipped pen to manually draw a line at the end of the cigarette, then wrap cotton thread around the line. When the cigarette burns to the line, the thread breaks, stopping the collection of particulate matter. This manual method usually only draws a line on one side of the cigarette, while wrapping the thread around the entire circumference makes it difficult to accurately align the line. If the drawing pressure is not controlled properly, the cigarette can be easily torn or punctured, resulting in its discard. A single experiment usually involves 100 cigarettes or more, making manual drawing time-consuming and labor-intensive. Furthermore, the accuracy is low, only reaching ±0.5mm, reducing the accuracy of the test data. Utility Model Content

[0045] The following is combined Figure 1 This application describes an automatic marking device for the end of cigarette combustion.

[0046] This utility model provides an automatic cigarette combustion termination marking device, which includes: a rotating assembly 1, a smoke exhaust assembly 3, and an inkjet assembly 2. The rotating assembly 1 is adapted to hold a cigarette 4 and drive the cigarette 4 to rotate; the smoke exhaust assembly 3 has a first station and a second station; at the first station, a support portion on the smoke exhaust assembly 3 extends to the bottom of the rotating assembly 1 to support the cigarette 4; at the second station, the support portion on the smoke exhaust assembly 3 moves to avoid the cigarette 4; the inkjet assembly 2 is disposed on one side of the rotating assembly 1 and is configured to spray ink onto the cigarette 4 while the smoke exhaust assembly 3 is at the first station and the rotating assembly 1 is driving the cigarette 4 to rotate.

[0047] In this embodiment, the rotating component 1 is designed with a mounting position that adapts to the shape and size of the cigarette 4, ensuring that the cigarette 4 can be placed stably on it. When a start signal is received, the rotating component 1 will drive the cigarette 4 to rotate at a stable speed, providing a stable motion platform for subsequent marking operations, so that the subsequent inkjet process can accurately cover all positions around the cigarette 4, ensuring the integrity and uniformity of the marking line.

[0048] The smoke exhaust assembly 3 has two states: a first working position and a second working position. When in the first working position, the support part on the smoke exhaust assembly 3 extends precisely to the bottom of the rotating assembly 1, providing stable and reliable support for the cigarette 4 placed on the rotating assembly 1. This prevents the cigarette 4 from tipping over or swaying due to lack of support during rotation, ensuring that the cigarette 4 maintains a good posture for marking operations. When it is necessary to replace the cigarette 4 or remove the marked cigarette 4, the smoke exhaust assembly 3 quickly switches to the second working position. At this time, the support part moves in time to avoid the location of the cigarette 4, making way for the smooth entry and exit of the cigarette 4, realizing seamless connection of the automatic positioning, rotation marking, and removal processes of the cigarette 4 in the device.

[0049] The inkjet unit 2 is aligned with the surface of the rotating cigarette 4. While the smoke exhaust unit 3 is in its first position and the rotating unit 1 drives the cigarette 4 to rotate, the inkjet unit 2 precisely sprays ink onto the surface of the cigarette 4 according to a preset marking program and parameters, forming a clear and durable combustion termination marking line. Thanks to the uniform rotation of the rotating unit 1, the inkjet unit can evenly spray a complete termination line around the cigarette 4 circumferentially.

[0050] The automatic cigarette combustion termination marking device provided by this utility model, through the integration of a rotating component 1, a smoke exhaust component 3, and an inkjet component 2, achieves fully automated operation of marking the combustion termination position of a cigarette 4, significantly improving detection efficiency and accuracy. The rotating component 1 drives the cigarette 4 to rotate at a uniform speed, and the inkjet component 2 sprays a termination line circumferentially onto the surface of the cigarette 4, ensuring the marking line completely surrounds the cigarette 4, completely solving the problem of positional deviation caused by traditional single-sided marking and cotton thread entanglement. The smoke exhaust component 3, through rapid switching between a first station (supporting the cigarette 4) and a second station (avoiding the cigarette 4), and in conjunction with the linkage control of the rotating component 1 and the inkjet component 2, achieves continuous operation of automatic positioning, rotation marking, and removal of the cigarette 4. Simultaneously, the use of inkjet technology to replace traditional pen-based marking forms a marking line on the surface of the cigarette 4 in a non-contact manner, completely eliminating the risks of uneven manual force leading to tearing of the cigarette paper and damage to the tobacco structure, reducing the scrap rate of experimental samples, and is particularly suitable for the precision marking needs of high-permeability cigarette paper.

[0051] In some embodiments, such as Figure 1 As shown, the rotating assembly 1 includes: a base plate 11, a limiting mechanism, and a driving mechanism. The limiting mechanism is rotatably mounted on the base plate 11 and is suitable for mounting the cigarette 4; the driving mechanism is mounted on the base plate 11 and is connected to the limiting mechanism for transmission, and is suitable for driving the limiting mechanism to rotate in coordination with the cigarette 4.

[0052] When the drive mechanism is activated, the power it generates is transmitted to the limiting mechanism through the transmission connection, thereby driving the limiting mechanism to rotate at a uniform and stable speed in conjunction with the cigarette 4. This design of the rotating component 1 not only ensures the stable rotation of the cigarette 4, but also facilitates precise control of the rotation speed according to actual needs, creating favorable conditions for the inkjet component 2 to form a complete and uniform combustion termination marking line on the surface of the cigarette 4.

[0053] In this embodiment, the limiting mechanism includes a limiting cylinder 12, a clamp 13, and a first pulley 14. The limiting cylinder 12 is connected to the base plate 11 and forms a mounting hole; a portion of the clamp 13 is disposed in the mounting hole for sleeved over the cigarette 4; the first pulley 14 is sleeved on another portion of the clamp 13 and is connected to the drive mechanism via a synchronous belt 15.

[0054] The automatic cigarette burning end marking device can be used in conjunction with the hopper to automatically mark cigarettes 4. When a single cigarette 4 falls into the limiting cylinder 12 from the hopper, the smoke exhaust assembly 3 moves to the first station, its support extending to the bottom of the rotating assembly 1 to hold the cigarette 4, providing stable support for subsequent marking operations. Next, the clamp 13 automatically clamps the cigarette 4, and at this time, the drive mechanism drives the first pulley 14 via the synchronous belt 15, causing the clamp 13 and the cigarette 4 to rotate around the central axis one revolution. During this process, the inkjet assembly 2 works synchronously, forming a uniform and clear black line on the surface of the cigarette 4 as it rotates, completing the marking of the burning end position. Finally, the smoke exhaust assembly 3 moves to the second station, its support avoiding the cigarette 4, and the cigarette 4 automatically falls from the limiting cylinder 12 under gravity, preparing for the marking of the next cigarette 4. The entire device operates with a high degree of automation, achieving automatic positioning, marking, and removal of the cigarette 4 through precise mechanical design and coordinated control logic.

[0055] In addition, such as Figure 1 As shown, the drive mechanism includes a motor 16 and a second pulley 17. The motor 16, as a power source, is connected to the base plate 11, providing stable power support for the entire rotating assembly 1. The second pulley 17 is mounted on the rotating shaft of the motor 16. When the motor 16 starts, the rotating shaft drives the second pulley 17 to rotate. A synchronous belt 15 is mounted on the first pulley 14 and the second pulley 17, forming a closed-loop transmission system. When the second pulley 17 rotates under the drive of the motor 16, it drives the first pulley 14 to rotate synchronously through the transmission action of the synchronous belt 15. Since the first pulley 14 is connected to the clamp 13, the clamp 13, driven by the first pulley 14, carries the cigarette 4 in a stable rotational motion around the central axis.

[0056] In some embodiments, such as Figure 1As shown, the smoke extraction assembly 3 includes a support plate 31 and a cylinder 34; the support plate 31 is connected to the movable end of the cylinder 34. At a first station, the cylinder 34 drives the support plate 31 to extend to the bottom of the rotating assembly 1 to support the cigarette stick 4. At a second station, the cylinder 34 drives the support plate 31 to move out of the bottom of the rotating assembly 1 to discharge the cigarette stick 4 from the rotating assembly 1.

[0057] Specifically, when marking cigarette stick 4 is required, cylinder 34 is activated and drives tray 31 to move to the bottom of rotating assembly 1, i.e., to the first working position. At this time, tray 31 supports cigarette stick 4, ensuring its stability during rotation and preventing it from falling due to gravity, thus providing a solid foundation for subsequent marking operations. After marking is completed, cylinder 34 drives tray 31 to move out of the bottom of rotating assembly 1 and into the second working position, causing cigarette stick 4 to lose support and fall from rotating assembly 1 under gravity, thereby achieving automatic discharge of cigarette stick 4 and preparing for the marking of the next cigarette stick 4. Through the rapid switching of tray 31 between the two working positions driven by cylinder 34, the smoke exhaust assembly 3 can efficiently cooperate with rotating assembly 1 and inkjet assembly 2 to complete the automatic positioning, marking, and removal process of cigarette stick 4, greatly improving the working efficiency and automation level of the entire device, reducing manual intervention, and enhancing the stability and reliability of the equipment.

[0058] In this embodiment, as Figure 1 As shown, the smoke exhaust assembly 3 also includes: a scale strip 32 and an adjusting screw 33; the scale strip 32 is connected to the movable end of the cylinder 34, and the support plate 31 is movably connected to the scale strip 32 by the adjusting screw 33, so as to lock or loosen the support plate 31 and the scale strip 32 by adjusting the screw 33.

[0059] Specifically, the scale strip 32 extends along the length of the cigarette 4, and the support plate 31 is movable along the extension direction of the scale strip 32 via the adjusting screw 33. This design allows the position of the support plate 31 to be flexibly adjusted according to different lengths of cigarettes 4 (or different marking positions), ensuring that the support plate 31 can accurately support the bottom of the cigarette 4, and can be quickly moved away when the cigarette 4 needs to be discharged, without affecting the falling of the cigarette 4. By adjusting the screw 33, the operator can easily lock or loosen the connection between the support plate 31 and the scale strip 32, achieving precise adjustment of the position of the support plate 31, thereby improving the adaptability and versatility of the device and meeting the marking needs of cigarettes 4 of different specifications.

[0060] In some embodiments, such as Figure 1As shown, the inkjet assembly 2 includes an ink sac 21, an ink supply tube 22, and a printhead 24. The printhead 24 is positioned on one side of the rotating assembly 1, facing the cigarette stick 4, ensuring that ink can be accurately sprayed onto the surface of the cigarette stick 4 during inkjet printing. The ink sac 21 is connected to the printhead 24 via the ink supply tube 22. Ink is transported from the ink sac 21 to the printhead 24 through the ink supply tube 22, and then ejected from the printhead 24 to complete the marking process. This method enables the inkjet assembly 2 to stably and efficiently form clear marking lines on the cigarette stick 4, ensuring the accuracy and consistency of the marking.

[0061] For ease of installation, the inkjet assembly 2 also includes a support plate 23. The support plate 23 is connected to the bottom of the base plate 11, and its two sides are respectively formed with a first support portion for mounting the ink cartridge 21 and a second support portion for mounting the printhead 24. The support plate 23 not only provides stable support for the ink cartridge 21 and the printhead 24, but also makes the installation of the inkjet assembly 2 more convenient. It also helps maintain a stable connection between the ink cartridge 21 and the printhead 24, ensuring that ink can be smoothly delivered from the ink cartridge 21 to the printhead 24. The first and second support portions respectively mount the ink cartridge 21 and the printhead 24, ensuring the stability of the ink supply system and the accurate positioning of the printhead 24, thereby improving the accuracy and consistency of inkjet printing.

[0062] Based on the above embodiments, in some embodiments, such as Figure 2 As shown, the automatic cigarette burning end marking device also includes a collection box 5. The collection box 5 is located at the bottom of the rotating assembly 1.

[0063] When the tray 31 of the smoke exhaust assembly 3 moves out of the bottom of the rotating assembly 1 (i.e., to the second position) under the drive of the cylinder 34, the marked cigarettes 4 will fall from the rotating assembly 1 under the action of gravity. At this time, the collection box 5 is located directly below the rotating assembly 1 and can accurately catch the falling cigarettes 4, realizing the orderly collection of cigarettes 4.

[0064] The collection box 5 not only facilitates the organization and subsequent processing of the marked cigarettes 4, but also prevents the cigarettes 4 from scattering randomly after marking, helping to maintain a clean working environment and improve work efficiency. Furthermore, the collection box 5 can be designed to be detachable, allowing operators to clean and replace it regularly to accommodate different collection needs for varying quantities of cigarettes 4.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
