[0023] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention.

[0025] During the production of cigarettes, tobacco leaves need to be loosened. During the preparation of thin tobacco leaves (also known as tobacco flakes, reconstituted tobacco, or homogenized tobacco), adhesives and other additives are often added. This results in thin tobacco leaves being denser than conventional redried tobacco leaves, making loosening difficult.

[0026] In the related art, the loosening equipment has a poor loosening effect on thin tobacco leaves, and usually a large amount of agglomerated tobacco leaves will remain after the loosening process.

[0027] Therefore, the utility model provides a tobacco leaf processing device to improve the loosening effect of thin tobacco leaves during the production process of cigarette products.

[0028] In some embodiments of the tobacco processing device provided by the present invention, the tobacco processing device includes a conveying device, a detection device, and a loosening device. The conveying device is used to convey tobacco leaves, the detection device is configured to detect the type of tobacco leaves, and the loosening device is connected to the detection device by signal and is configured to loosen the tobacco leaves when the detection device detects that the tobacco leaves are thin tobacco leaves.

[0029] In the production process of cigarette products, different types of tobacco leaves may be used depending on production needs.

[0030] The conveying device can be used to transport different tobacco leaves to different process links.

[0031] By setting up a detection device to detect the type of tobacco leaves conveyed by the conveying device, and setting up a loosening device to loosen the tobacco leaves only when the detection device detects thin tobacco leaves, it is possible to loosen only thin tobacco leaves in the current processing link, thereby avoiding unnecessary processing of tobacco leaves that do not need to be loosened (such as conventional redried tobacco leaves), thereby improving the overall efficiency of the production line.

[0032] Among them, the loosening device can be set to loosen thin tobacco leaves specifically, and the loosened thin tobacco leaves can be directly transported to subsequent process links; or, the loosening device can also be set to pre-loosen the thin tobacco leaves. The thin tobacco leaves loosened in this process can be further mixed with other types of tobacco leaves and loosened for the second time through the conventional loosening process in the cigarette product production process, so as to achieve sufficient loosening of the thin tobacco leaves.

[0033] There are many feasible methods for detecting tobacco leaf types, so different types of detection devices can be selected based on the needs. For example, optical sensors, conductivity meters, ultrasonic detectors, etc. can be used to distinguish different types of tobacco leaves based on parameters such as optical information, conductivity, and ultrasonic echo information.

[0034] refer to Figure 1 As shown, in some embodiments, the detection device includes an image acquisition unit 1 and a control unit, the image acquisition unit 1 is configured to acquire images of tobacco leaves, and the control unit is configured to obtain the type of tobacco leaves based on the images.

[0035] The image acquisition unit 1 can be a camera, an image sensor or other equipment.

[0036] The image acquisition unit 1 is used to acquire tobacco leaf images, so that the control unit can obtain the type of tobacco leaves currently on the conveying device based on distinguishing features such as color, shape, texture, etc. of the tobacco leaves in the acquired images.

[0037] Here, the control unit can be a general-purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic device, discrete hardware component or any appropriate combination thereof for performing the functions described in this application.

[0038] Furthermore, the image acquisition unit 1 can also be used to capture images of personnel. By adjusting the shooting angle and range of the image acquisition unit 1, it can also be used to obtain images at different locations on the production site.

[0039] For example, in some embodiments, the image acquisition unit 1 captures images of the conveying surface of the conveying device. In this case, the control unit can obtain the type of tobacco leaves on the conveying surface through the images captured by the image acquisition unit 1, and can also identify whether there are people performing operations on the conveying surface, such as checking the status of the tobacco leaves, adjusting the position of the tobacco leaves, checking the equipment condition, etc.

[0040] Operating loose devices may endanger the safety of personnel if they are on the conveying surface or in close proximity to loose devices.

[0041] Therefore, in some embodiments, the tobacco processing equipment also includes a protective device, and the detection device is also configured to detect whether there is a person at a preset position of the conveying device. The protective device is connected to the detection device and the loosening device signal, and the protective device is configured to control the loosening device to shut down when the detection device detects the presence of a person, so as to effectively protect the life safety of the personnel.

[0042] The preset position may be on the conveying surface, or other positions on the conveying device close to the loosening device, or any position that may be affected by moving parts of the loosening device.

[0043] refer to Figure 1 As shown, in some embodiments, the loosening device includes a blade 2, which is configured to be inserted into the tobacco leaves and rotated to loosen the tobacco leaves.

[0044] In practical applications, the shape and specifications of the scraper 2 can be designed differently, and the rotation speed and insertion depth of the scraper 2 can also be adjusted to adapt to different production requirements. For example, the relevant parameters can be selected according to the conveying flow rate of the conveying device.

[0045] refer to Figure 1 As shown, in some embodiments, the loosening device also includes a first drive device and a second drive device connected to the blade 2, the first drive device is configured to drive the blade 2 close to or away from the conveying surface of the conveying device so that the blade 2 is inserted into the tobacco leaves or pulled out from the tobacco leaves, and the second drive device is configured to drive the blade 2 to rotate so that the blade 2 loosens the tobacco leaves.

[0046] By adjusting the relevant parameters of the first drive unit, the depth of blade 2's insertion into the tobacco leaves can be adjusted. By adjusting the relevant parameters of the second drive unit, the rotation period and speed of blade 2 can be adjusted. The coordinated operation of the first and second drive units allows the loosening intensity of the loosening device to be adjusted, ensuring that the loosening process is neither too strong, causing unnecessary damage to the tobacco leaves, nor too gentle, resulting in poor loosening results.

[0047] In some embodiments, the moving direction of the blade 2 is perpendicular to the conveying surface of the conveying device.

[0048] The blade 2 moves perpendicularly to the conveying surface. Firstly, the movement efficiency is high. Secondly, it can ensure that the blade is accurately inserted into the tobacco leaves and no unnecessary damage is caused to the tobacco leaves during the insertion and withdrawal process.

[0049] In the embodiment of the present application, there are multiple options for the specific structural forms of the first driving device and the second driving device.

[0050] For example, the first driving device may be a linear guide, a pneumatic cylinder, a hydraulic cylinder, a screw-nut mechanism, a linear motor, etc., and the second driving device may be an electric motor, a belt / gear transmission system, etc.

[0051] Specifically, in some embodiments, the first driving device includes a cylinder; and / or the second driving device includes a motor.

[0052] refer to Figure 1 As shown, in some embodiments, the loosening device includes a plurality of blades 2, and the plurality of blades 2 are spaced apart along a first direction, and the first direction is perpendicular to the conveying direction of the conveying device.

[0053] The simultaneous operation of multiple scrapers 2 can significantly improve the loosening efficiency.

[0054] like Figure 1 As shown in the figure, the conveying direction of the conveyor device is the x-direction in the figure, and the first direction is the y-direction in the figure. The first direction is perpendicular to the conveying direction of the conveyor device, which allows the multiple scrapers 2 to loosen the tobacco leaves at various positions within the width of the conveying surface, ensuring that the tobacco leaves are fully loosened.

[0055] In practical applications, the number or spacing of the scrapers 2 can also be adjusted to meet the processing requirements of different types or quantities of tobacco leaves.

[0056] refer to Figure 1 As shown, in some embodiments, the tobacco leaf processing equipment further comprises a mounting frame 4 arranged above the conveying surface of the conveying device, and the loosening device is mounted on the mounting frame 4.

[0057] Specifically, the mounting frame 4 supports and secures the loosening device. A first drive unit is connected between the mounting frame 4 and the scraper 2. When the tobacco leaves need to be loosened, the scraper 2 is driven downward by the first drive unit. Once the loosening is complete, the first drive unit retracts the scraper 2, moving it away from the conveying surface, allowing the conveyor to continue conveying the tobacco leaves.

[0058] A specific embodiment of the tobacco leaf processing equipment of the present invention is described below:

[0059] refer to Figure 1 As shown, the tobacco leaf processing equipment of the present application includes a conveying device, a detection device, a loosening device, a protective device, and a mounting frame 4. Among them, the conveying device is used to convey tobacco leaves, the detection device is configured to detect the type of tobacco leaves, and the loosening device is connected to the detection device by signal. The loosening device is configured to loosen the tobacco leaves when the detection device detects that the type of tobacco leaves is thin tobacco leaves.

[0060] The conveying device includes a roller 5, a frame 6 and a conveying belt 7. The conveying belt 7 is tensioned on the roller 5 to drive the conveying belt 7 to move through the roller 5. The frame 6 is arranged on both sides of the conveying belt 7 to form a conveying space for conveying tobacco leaves between the inner wall of the frame 6 and the conveying belt 7.

[0061] The loosening device includes a first driving device, a second driving device and a plurality of scrapers 2 arranged in a row.

[0062] In this embodiment, the first driving device is the cylinder 3, and the second driving device is the motor.

[0063] The cylinder 3 includes a cylinder body and an output rod connected to the cylinder body. The cylinder body is mounted on a mounting frame 4 , and the motor is connected between the output rod of the cylinder 3 and the blade 2 .

[0064] The detection device includes an image acquisition unit 1, a support frame 8, and a control unit. The support frame 8 is positioned adjacent to the conveyor belt 7, and the image acquisition unit 1 is mounted on the support frame 8, with the image acquisition unit 1 oriented toward the surface of the conveyor belt 7 (i.e., the conveying surface of the conveyor device).

[0065] In this embodiment, the image acquisition unit 1 is a camera.

[0066] During the production process of cigarette products, when the tobacco leaves after the slicing process are transported to the shooting range of the image acquisition unit 1 via the conveyor belt 7, the image acquisition unit 1 captures the image of the tobacco leaves and transmits it to the control unit. The control unit determines the type of tobacco leaves currently on the conveyor belt 7 based on the different physical properties of thin tobacco leaves and conventional tobacco leaves (such as re-roasted tobacco leaves).

[0067] When the control unit determines that the tobacco leaves currently on the conveyor belt 7 are regular tobacco leaves, the cylinder 3 keeps its output rod in a retracted state and the scraper 2 does not move. When the control unit determines that the tobacco leaves currently on the conveyor belt 7 are thin tobacco leaves, the cylinder 3 extends its output rod, and the scraper 2 moves downward under the drive of the output rod, and the motor drives the scraper 2 to rotate around its own center line (for example, clockwise) to loosen the thin tobacco leaves.

[0068] In addition, when the control unit recognizes that a person is working on the conveyor belt 7 based on the image captured by the image acquisition unit 1, the protective device will automatically control the loosening device to stop suddenly to ensure the life safety of the operator.

[0069] Through the description of multiple embodiments of the tobacco leaf processing equipment of the present invention, it can be seen that the tobacco leaf processing equipment of the present invention is provided with a detection device and a loosening device that work together. When the detection device detects thin tobacco leaves, the loosening device is started, which can effectively solve the problem that traditional equipment has poor loosening effect on thin tobacco leaves. At the same time, it can avoid unnecessary processing of conventional tobacco leaves and improve the overall efficiency of the production line.

[0070] Based on the above tobacco processing equipment, the present invention also provides a cigarette making system, which includes the above tobacco processing equipment. The positive technical effects of the tobacco processing equipment in the above embodiments are also applicable to the cigarette making system and will not be repeated here.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that without departing from the principles of the present invention, the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents. These modifications and equivalent replacements should all be included in the scope of the technical solutions claimed for protection in the present invention.
