Technical Field
[0001] This application relates to the field of conveying equipment technology, and in particular to a conveying device and tobacco processing equipment. Background Technology
[0002] In cigarette production, materials such as tobacco leaves and shredded tobacco are mostly transported by vibrating conveyors. However, due to differences in material type, grade, flow rate, and other factors, material accumulation and blockage often occur during the conveying process, affecting the continuity of production. Utility Model Content
[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a conveying device and tobacco processing equipment that can alleviate the problem of material blockage, ensure the continuity and stability of production, and improve production efficiency.
[0004] This application provides the following technical solution: In a first aspect, embodiments of this application provide a conveying device, the conveying device comprising: The vibratory conveying assembly includes a conveying member having an upward-facing vibratory conveying groove for vibrating conveying of materials. Anti-clogging component, the anti-clogging component comprising at least one of the following structures: At least one scraper has a scraping area for pushing and scraping material in the scraping area. The scraping area is located above the vibrating conveying trough, and a material passage gap is formed between the scraping area and the bottom of the vibrating conveying trough. At least one purging element is provided for delivering a purging airflow to the vibrating conveyor trough.
[0005] In some embodiments of the first aspect, the anti-clogging component includes at least one of the scraper elements; The scraper includes a scraping part and a driving part. The scraping part is located above the vibrating conveying trough, and the gap between the scraping part and the vibrating conveying trough forms the material passage gap. The driving part is connected to the scraping part, and the driving part can drive the scraping part to move along the conveying direction parallel to the vibrating conveying trough.
[0006] In some embodiments of the first aspect, the driving unit includes a drive motor and a lead screw and nut mechanism, the main shaft of the drive motor is connected to the driving end of the lead screw and nut mechanism, the drive motor is used to drive the driving end to rotate, the driven end of the lead screw and nut mechanism is connected to the scraping part, and the moving direction of the driven end is parallel to the conveying direction.
[0007] In some embodiments of the first aspect, the scraping part is a cleaning brush.
[0008] In some embodiments of the first aspect, the blowing direction of the purging member has a reverse component along the conveying direction.
[0009] In some embodiments of the first aspect, the conveying device further includes: A monitoring component includes multiple camera units, which are spaced apart along the extension direction of the vibrating conveyor trough, and the camera units are used to acquire images on the vibrating conveyor trough.
[0010] In some embodiments of the first aspect, the monitoring component further includes a control unit electrically connected to each of the camera unit, scraper, and purging unit.
[0011] In some embodiments of the first aspect, the control unit further includes a wireless communication unit for electrical connection with a mobile terminal.
[0012] In some embodiments of the first aspect, the control unit further includes an analysis unit for generating an alarm signal when material blockage occurs.
[0013] Secondly, embodiments of this application also provide a tobacco processing device, which includes a conveying device as described in any of the above embodiments.
[0014] The embodiments of this application have the following advantages: This application provides a conveying device that combines active intervention and prevention, using both physical scraping and airflow purging to solve material blockage problems during vibratory conveying. Materials (such as tobacco leaves and shredded tobacco) are fed into a vibratory conveying trough formed by the conveying components of a vibratory conveyor. Driven by a vibrating motor or other vibration source, the conveying components generate high-frequency micro-amplitude vibrations, causing the material to jump forward in a predetermined direction within the trough, completing the conveying process. Scraping components (such as scrapers or rakes) are positioned above the vibratory conveying trough, with a preset material passage gap maintained between the scraping area at their lower edge and the trough bottom. This gap allows a normal flow of material to pass smoothly, but when the material begins to accumulate locally and adhere to the trough bottom due to increased humidity, viscosity, or flow rate, the accumulation height will exceed the material passage gap. At this point, the scraping components will come into contact with the excessively high material. As the conveying components vibrate, the scraping components continuously block, break up, and push the accumulated material, dispersing the clumps and forcibly pushing them forward, thereby clearing the blockage and ensuring normal material flow.
[0015] Purging components (such as nozzles and jet pipes) are installed at critical locations in the conveying trough (such as easily clogged corners or outlets). Through an external air source connection, a continuous or intermittent purging airflow is injected into the vibrating conveying trough. This airflow serves multiple purposes: first, it uses the kinetic energy of the airflow to directly disperse slightly accumulated material; second, it forms an air cushion, reducing the adhesion and friction between the material and the trough bottom, preventing damp material from adhering; and third, it dries the material surface, further reducing the possibility of adhesion.
[0016] The scraper and purging components can be used individually or in combination. When used in combination, they create a stronger anti-clogging capability. For example, the purging component first disperses loose deposits and reduces material viscosity, while the scraper then physically clears the blockage, achieving uniform material feeding. The two components complement each other.
[0017] Therefore, this application effectively alleviates material blockage and ensures production continuity. Through the mechanical scraping of the scraper and the airflow disturbance of the purging component, it can proactively and promptly remove or prevent the accumulation and adhesion of materials in the conveying trough, fundamentally solving the production interruption problem caused by material blockage and ensuring the stable and continuous operation of the filament production line. Furthermore, it improves production efficiency and automation, reduces downtime for cleaning and the frequency of manual intervention required to handle blockages, and increases the effective operating rate of the equipment. The production process is smoother, overall production efficiency is significantly improved, and the labor intensity of workers is reduced.
[0018] Furthermore, the anti-clogging component offers two optional or combined solutions: scraping and blowing. Users can select the most suitable anti-clogging method and combing intensity based on the specific characteristics of the material (such as grade, humidity, and flow rate), enhancing the equipment's adaptability to different production conditions.

[0028] In related technologies, tobacco leaves, shredded tobacco, and other materials are mostly transported via vibrating conveyors during cigarette production. However, due to differences in material type, grade, flow rate, and other factors, material accumulation and blockage often occur during transport, affecting the continuity of production.
[0029] As shown in Figure 1, Figure 2 and Figure 3 As shown, in order to solve the above-mentioned technical problems, this application provides a conveying device, which includes: A vibrating conveying assembly, the vibrating conveying assembly including a conveying member 1, the conveying member 1 being formed with an upward vibrating conveying groove for vibrating conveying of materials; Anti-clogging component, the anti-clogging component comprising at least one of the following structures: At least one scraper has a scraping area for pushing and scraping material in the scraping area. The scraping area is located above the vibrating conveying trough, and a material passage gap is formed between the scraping area and the bottom of the vibrating conveying trough. At least one purging element 3 is provided for conveying purging airflow into the vibrating conveying trough.
[0030] In these embodiments, this application provides a conveying device for a tobacco spinning line, including a vibrating conveying assembly and an anti-clogging assembly.
[0031] The vibratory conveying assembly includes a conveyor 1, which has a trough-shaped structure with an upward-facing vibratory conveying trough formed on its upper surface. The conveyor 1 is driven by a vibratory motor (not shown) at its bottom to generate directional vibration, thereby conveying tobacco leaves or shredded tobacco forward along the conveying direction.
[0032] The anti-clogging component includes a scraper disposed above the vibrating conveyor trough, located in the middle of the conveying path. For example, the scraper includes an elastic rubber plate, the lower edge of which forms a scraping area. A material passage gap with a height of 15mm is formed between the scraping area and the bottom of the vibrating conveyor trough. When material tends to accumulate locally during conveying, with the vibration of the conveyor 1, the accumulated material rises to the scraping area, is pushed and dispersed by the lower edge of the scraper, and excess material is redistributed or falls back to the bottom of the trough, thereby preventing blockage. It also enables uniform material feeding.
[0033] For example, the scraper is fixed to the frame of the conveying device by the bracket 10, and its position can be adjusted in the vertical direction to adapt to different material types and flow requirements, so as to realize the adjustable material gap H, for example, the adjustment range is 5-30mm.
[0034] In this embodiment, the elastic rubber plate is inclined along the material conveying direction, with its front end (upstream side) lower than its rear end (downstream side), forming a structure that is low in the front and high in the back. This is beneficial for guiding the material forward during the pushing and scraping process and avoiding reverse accumulation.
[0035] Therefore, by incorporating scrapers, accumulated materials are effectively dispersed, preventing bridging or blockage within the vibrating conveyor trough. This significantly improves the continuity and stability of the conveying process, making it suitable for conveying easily agglomerated materials such as tobacco leaves and stems. It also enables uniform material conveying.
[0036] In addition, this application also provides another embodiment, which has the same basic structure as the aforementioned embodiment, except that the anti-blocking component includes a purging element 3 instead of a scraping element.
[0037] For example, the purging element 3 is an air jet head facing the interior of the vibrating conveyor trough. The purging element 3 is connected to the factory compressed air system via an air pipe, which can provide a clean purging airflow with a pressure of 0.4 to 0.6 MPa.
[0038] During material conveying, when the control system detects that the thickness of a section of material exceeds a threshold (which can be monitored by an infrared sensor or vision system), it automatically activates the purging component 3 to spray transverse airflow into the vibrating conveyor trough. This airflow disturbs the material layer, breaks down the adhesion between materials, loosens the accumulated areas, and restores smooth flow.
[0039] The purging component 3 can be installed at easily clogged points in the conveying path, such as bends or downstream of the discharge port. Its start and stop can be dynamically adjusted by the PLC control system according to the production flow rate to achieve intelligent anti-clogging.
[0040] Therefore, by using airflow disturbance to prevent material accumulation in a non-contact manner and avoid mechanical scraping that could damage the tobacco, it is particularly suitable for conveying tobacco with high brittleness.
[0041] Furthermore, this embodiment also provides a composite anti-blocking conveying device, wherein the anti-blocking component includes both a scraper and a blower 3.
[0042] The scraper is located at the front of the conveying path to initially break up large accumulations. The purging component 3 is located at the rear to further agitate the airflow and ensure uniform material delivery. The two work together to form a multi-stage anti-blocking mechanism.
[0043] Under conditions of high flow rate or excessive humidity, the system can simultaneously activate scraping and blowing functions, significantly improving its anti-clogging capability.
[0044] In some embodiments, the anti-clogging component includes at least one of the aforementioned scraping elements. The scraping element includes a scraping portion 9 and a driving portion. The scraping portion 9 is located above the vibrating conveying trough, and the gap between the scraping portion 9 and the vibrating conveying trough forms a material passage gap. The driving portion is connected to the scraping portion 9, and the driving portion is capable of driving the scraping portion 9 to move along a conveying direction parallel to the vibrating conveying trough.
[0045] In these embodiments, the anti-clogging component includes at least one scraper that not only has a static scraping function but also an active reciprocating motion capability to enhance the scraping and clearing effect on the accumulated material.
[0046] The scraping component includes a scraping part 9 and a driving part.
[0047] For example, the scraper 9 is a long strip scraper that spans the width of the vibrating conveyor trough. Its bottom edge is located above the vibrating conveyor trough and forms a height-adjustable material passage gap with the bottom of the trough. The bottom edge of the scraper 9 has a rounded chamfer to avoid scratching and damaging the tobacco. Its material can be stainless steel or engineering plastic, taking into account both strength and wear resistance.
[0048] The drive unit includes a servo motor and a crank-connecting rod mechanism (or a reciprocating drive device such as a linear cylinder or electric actuator). The drive unit is connected to the scraping unit 9 and can drive the scraping unit 9 to perform reciprocating linear motion along the conveying direction parallel to the vibrating conveying trough.
[0049] For example, the servo motor converts the rotary motion into the horizontal reciprocating motion of the scraper 9 through a crank-connecting rod mechanism. When material accumulation is detected, the control system activates the drive unit. During the reciprocating motion, the scraper 9 continuously pushes and scrapes the accumulated material in front, pushing and breaking it up. At the same time, when it moves backward, it allows subsequent material to continue to be conveyed through the material passage gap, forming a dynamic unblocking mechanism.
[0050] The start / stop and motion parameters of the drive unit can be automatically adjusted by the PLC system based on parameters such as production flow rate and material humidity. For example, under high humidity and high flow conditions, the reciprocating frequency can be increased; under normal operating conditions, it can operate intermittently to save energy.
[0051] Compared to static scrapers, the reciprocating drive scraper 9 in this embodiment can more actively and effectively prevent materials from continuously accumulating in local areas, making it particularly suitable for tobacco conveying scenarios with high viscosity or frequent flow fluctuations.
[0052] In other embodiments, the anti-clogging component includes multiple scraping elements arranged at intervals along the conveying direction of the vibrating conveyor trough. Each scraping element includes an independent scraping part 9 and a driving part, which can reciprocate synchronously or at different times.
[0053] For example, the front scraper operates at a lower frequency for initial dispersal; the rear scraper starts at a higher frequency when it detects increased pressure, creating a gradient anti-clogging mechanism. This multi-stage scraping structure can adapt to longer conveying distances and more complex operating conditions, further improving anti-clogging reliability.
[0054] In some embodiments, the drive unit includes a drive motor 2 and a lead screw and nut mechanism 5. The main shaft of the drive motor 2 is connected to the drive end of the lead screw and nut mechanism. The drive motor 2 is used to drive the drive end to rotate. The driven end 7 of the lead screw and nut mechanism is connected to the scraping part 9. The moving direction of the driven end 7 is parallel to the conveying direction.
[0055] In these embodiments, the structure of the drive unit is specified to provide a high-precision, stable and reliable reciprocating drive solution.
[0056] The drive motor 2 can be either a stepper motor or a servo motor. The lead screw and nut transmission mechanism includes a lead screw and a nut slider.
[0057] The main shaft of the drive motor 2 is connected to the drive end of the lead screw via a coupling, and the drive motor 2 drives the lead screw to rotate when it is working. The nut slider is sleeved on the lead screw and serves as the driven end 7 of the transmission mechanism. It moves linearly along the lead screw axis as the lead screw rotates.
[0058] The nut slider is fixedly connected to the scraping part 9 through a connector, so that the scraping part 9 moves back and forth along the conveying direction parallel to the vibrating conveying groove together with the nut slider.
[0059] To ensure smooth movement and guiding accuracy, this embodiment also includes a guiding component, such as a linear guide or an optical axis slider structure, which is set at the support points on both sides of the scraping part 9 to constrain it to move linearly in a predetermined direction and prevent jamming or wear due to off-center loading.
[0060] In addition, the lead screw and nut mechanism 5 has a self-locking feature, which can keep the scraper part 9 in a fixed position when the motor is powered off, so as to avoid accidental displacement from affecting the conveying.
[0061] Screw and nut drives offer higher motion precision and controllability, making them particularly suitable for high-end tobacco processing lines that require precise control of the scraping rhythm and position. Furthermore, they are compact, easy to maintain, and exhibit good long-term operational stability.
[0062] In some embodiments, the driven end 7 is provided with a swing motor 6, the main shaft of which is connected to a swing arm 8. The swing arm 8 is connected to a scraper 9, and the swing motor 6 is used to drive the swing arm 8 and the scraper 9 to swing, thereby adjusting the lower gap. For example, the scraper 9 can be adjusted to contact the bottom of the tank to clean the residual material at the bottom of the tank.
[0063] In some embodiments, the scraping part 9 is a cleaning brush.
[0064] In these embodiments, the scraping part 9 is a cleaning brush, which includes a brush body and bristles densely distributed on the brush body. The cleaning brush spans the width of the vibrating conveyor trough, with the bristles at its bottom extending above the vibrating conveyor trough, and a material passage gap is formed between the bottom of the bristles and the bottom of the trough. This gap allows material of normal thickness to pass through, while applying a flexible scraping action to accumulated material exceeding the height of the gap.
[0065] The cleaning brush is connected to the drive unit (such as the nut slider of the lead screw and nut mechanism 5) via the mounting base, so that it can reciprocate linearly along the conveying direction parallel to the vibrating conveying groove with the drive unit.
[0066] For example, the brush body can be made of aluminum alloy or engineering plastic tubing, which is lightweight and corrosion-resistant. The bristles are preferably made of nylon, pig bristles, or soft polypropylene fibers, which have appropriate elasticity and can bend and deform during scraping, avoiding mechanical damage such as breakage or crushing of the tobacco.
[0067] The density and length of the bristles can be adjusted according to the characteristics of the material. For example, for brittle tobacco, longer and sparser soft bristles are used; for materials with more stems, denser and slightly harder bristles are used to enhance the scraping force.
[0068] During operation, as the cleaning brush moves back and forth, the tips of its bristles push the accumulated tobacco forward, while the gaps between the bristles allow some small materials to pass through. Compared to rigid scrapers, the brush agitates the material more evenly, making it particularly suitable for conveying tobacco with high packing density, fragility, or high moisture content.
[0069] In addition, the cleaning brush has a certain self-cleaning ability during reciprocating motion, preventing material from adhering and clogging the gaps between the bristles.
[0070] In some embodiments, the blowing direction of the purging member 3 has a reverse component along the conveying direction.
[0071] In these embodiments, the airflow direction of the purging element 3 is optimized to provide a more effective purging and anti-clogging solution.
[0072] For example, the purging component 3 includes a long strip-shaped air duct arranged along the width of the vibrating conveying trough, with multiple inclined air outlets or nozzle arrays at its bottom. Crucially, the jet direction of the purging airflow is not perpendicular to or completely in the same direction as the conveying direction, but rather has a reverse angle relative to the conveying direction; that is, the airflow direction has a reverse component along the conveying direction.
[0073] Specifically, the angle between the axis of the vent and the conveying direction is 100° to 160° (i.e., 20° to 80° with the opposite direction). The reverse component applies a reverse thrust to the forward-moving material, causing it to generate a "pull-forward surge" wave effect, effectively breaking up material clumps that are about to form bridges.
[0074] Compared to forward or vertical purging, the oblique purging with a reverse component in this embodiment significantly improves the anti-clogging capability for high-density, high-humidity materials. Under the same air pressure, this structure can shorten the material removal time and reduce the required airflow, resulting in significant energy savings.
[0075] In other embodiments, the purging member 3 can integrate multiple exhaust ports, each with a different spray angle, for example: First exhaust port: The jet direction has a reverse component, used for strong disturbance; The second exhaust port has a nearly vertical spray direction and is used to lift materials. The third exhaust port has a forward component in the injection direction, which is used to assist in pushing.
[0076] In some embodiments, the conveying device further includes a monitoring component, which includes a plurality of camera units 4 spaced apart along the extension direction of the vibrating conveying trough, the camera units 4 being used to acquire images on the vibrating conveying trough.
[0077] In these embodiments, the material status within the vibrating conveyor trough is sensed in real time to achieve precise response and closed-loop control of the anti-blocking component.
[0078] The conveying device includes a monitoring component, which includes multiple camera units 4 (such as industrial cameras or vision sensors). The multiple camera units 4 are arranged at intervals along the extension direction of the vibrating conveyor trough (i.e. the material conveying direction) to cover key areas of the entire conveying path, such as: the inlet section (downstream of the discharge port), the middle section (easy accumulation area), the turning point or diameter change section, and the outlet section (before connecting to the next level equipment).
[0079] Each camera unit 4 is fixed to the bracket 10 or protective cover of the conveying device, with its lens facing the inside of the vibrating conveying trough, for continuously or periodically acquiring real-time images of the material inside the trough. The camera unit 4 is preferably a high frame rate, high resolution industrial camera, with vibration resistance, dustproof, smokeproof, and night vision capabilities, and can work stably in the complex environment of a tobacco workshop.
[0080] Multiple camera units 4 are connected to an image processing unit (such as an embedded industrial computer or edge computing module) via data cables (such as Ethernet or industrial bus). The image processing unit runs image recognition algorithms (such as a semantic segmentation model based on deep learning or a traditional edge detection algorithm) to analyze the images acquired by each camera unit 4 and identify the following states: material thickness / stacking height, material flow rate, whether bridging, clumping or local blockage tendencies occur, and the spatial location of the blockage area.
[0081] When image analysis indicates that the material height in a certain area exceeds a preset threshold (e.g., exceeding 80% of the material passage gap), or when flow stagnation is detected, the image processing unit generates a blockage warning signal and activates the anti-blockage component in the corresponding area based on the blockage location. Alternatively, manual activation control can be used.
[0082] For example, if accumulation occurs in the inlet section, the purging component 3 in that area is activated (using reverse component airflow).
[0083] By setting up multiple cameras 4 distributed along the conveying direction, full coverage and high-precision visual monitoring of the entire conveying path is achieved, avoiding the blind spot problem of single-point monitoring. Combined with existing image recognition algorithms, the system can predict material blockage trends in advance, realizing intelligent anti-blockage control of "early detection, accurate positioning, and fast response", significantly improving the system's automation level and operational reliability.
[0084] Of course, it should be noted that the camera unit 4 can also be used only for acquiring images, with the drive unit manually controlled.
[0085] In other embodiments, the spacing between the multiple camera units 4 is dynamically adjusted according to the transport length and risk level, for example, denser arrangement in areas prone to congestion (1-2 meters spacing) and sparse arrangement in areas with stable conditions (3-5 meters spacing).
[0086] To ensure image quality, each camera unit 4 is equipped with a supplementary light (such as an LED strip light) to provide uniform illumination and avoid shadow interference. The supplementary light can be turned on and off synchronously with the camera unit 4, or its brightness can be automatically adjusted according to the ambient light intensity.
[0087] In some embodiments, the monitoring component further includes a control unit, which is electrically connected to each of the camera units 4, the scraper, and the blower 3.
[0088] These embodiments further improve the system architecture of the monitoring component, providing a centralized and intelligent closed-loop control solution.
[0089] The monitoring components also include a control unit (i.e., a central controller), which is a programmable logic controller (PLC), an industrial computer (IPC), or an embedded microprocessor system, and has data processing, logic judgment, and instruction output functions.
[0090] The control unit is electrically connected to the following components via industrial communication buses (such as PROFINET, EtherCAT, or Modbus TCP): Each camera unit 4: receives image data transmitted in real time from each camera unit 4; The drive unit of the scraper (such as a servo motor or stepper motor): sends control commands such as start / stop, reciprocating frequency, and stroke. The solenoid valve or pneumatic control unit of the purging component 3 sends commands such as opening, closing, and airflow intensity adjustment.
[0091] The workflow is as follows: Each camera unit 4 periodically acquires material images from different sections within the vibrating conveyor trough and transmits the image data to the control unit in real time (or after preprocessing by the image processing unit). The control unit has a built-in image recognition algorithm module that analyzes the images to determine whether there is material accumulation, abnormal flow, or blockage trend in each monitored section, and identifies its location and severity. The control unit generates control commands based on preset control strategies (such as threshold judgment, fuzzy logic, or machine learning models): if the material height in a section exceeds the first threshold, the corresponding scraper for that section is activated for preventative clearing via low-frequency reciprocating operation. If the material height exceeds the second threshold or bridging occurs, the purging unit 3 for that section is activated simultaneously, using a diagonal airflow with a reverse component for strong disturbance. If multiple sections are abnormal simultaneously, multiple anti-blockage devices are activated in priority order or in a coordinated manner. After the blockage is cleared, the relevant devices automatically stop and enter standby mode.
[0092] In some embodiments, the control unit further includes a wireless communication unit for electrical connection with a mobile terminal.
[0093] In these embodiments, the control unit further includes a wireless communication unit, which is integrated within the control unit or electrically connected to it as an external module. The wireless communication unit supports one or more industrial-grade wireless communication protocols, such as Wi-Fi 6, 4G / 5G, Bluetooth 5.0, Zigbee, or LoRa.
[0094] The wireless communication unit is used to establish a wireless communication connection with the mobile terminal to achieve data interaction. The mobile terminal includes: Smartphones, tablets, industrial handheld PDAs, and portable devices running dedicated apps or web clients.
[0095] Through this wireless connection, the mobile terminal can perform the following functions: The mobile terminal can view the images collected by each camera 4, the material accumulation status, the operating status of the anti-blocking components (whether the scraper is running, whether the blowing component 3 is turned on), vibration frequency and other key parameters in real time through a dedicated application.
[0096] Operators can manually start or stop specific sections of the scraper or purging component 3, or adjust their operating parameters (such as reciprocating frequency and purging duration) via a mobile terminal from a location far from the equipment site (such as the control room, office, or any location in the plant area), to achieve emergency intervention or debugging.
[0097] When the control unit detects a risk of material blockage or equipment malfunction, it sends an audible and visual alarm, pop-up message, or SMS notification to the bound mobile terminal via the wireless communication unit to remind relevant personnel to handle the situation in a timely manner and shorten the response time.
[0098] In some embodiments, the control unit further includes an analysis unit for generating an alarm signal when material blockage occurs.
[0099] In these embodiments, when a blockage occurs in the analysis unit, an alarm signal is generated immediately. This alarm signal can be output in several ways: Local audible and visual alarm: Triggers on-site buzzer and warning light; Control command linkage: Automatically activate the scraper and / or purging component 3 in the corresponding section for emergency unblocking; Remote notification: Alarm information (such as pop-ups or vibration alerts) is pushed to the bound mobile terminal via the wireless communication unit. It should be noted that the above signal transmission control is existing technology and will not be elaborated upon here.
[0100] In some embodiments, this application also provides a tobacco processing apparatus, which includes any of the conveying devices described in the above embodiments.
[0101] Since the aforementioned conveying device has the aforementioned technical effects, the tobacco processing equipment including the conveying device should have the same technical effects, which will not be elaborated here.
