Technical Field

[0001] This application belongs to the field of tobacco production logistics technology, specifically relating to a temperature measuring device and a tobacco box conveying system. Background Technology

[0002] During tobacco processing and storage, the quality of tobacco leaves is closely related to storage conditions, with temperature being a key parameter. If the temperature is too high or unevenly distributed during storage, the quality of the tobacco leaves may decline, leading to problems such as mold growth and abnormal fermentation. This, in turn, affects the taste and quality of tobacco products, causing economic losses to tobacco companies.

[0003] Traditional methods for detecting the temperature of tobacco leaves often rely on manual sampling. This method is not only inefficient, but also has limited accuracy and representativeness, making it difficult to comprehensively and in real time grasp the temperature of tobacco leaves in large-scale storage environments. Utility Model Content

Simultaneously, the temperature acquisition unit can directly insert into the smoke box to collect the temperature of the tobacco sheets. Compared to the traditional method of manually cutting the packing straps to open the smoke box, this not only avoids wasting packing straps but also fundamentally improves the accuracy of the inspection results.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0045] See Figures 1 to 3As shown, an embodiment of the first aspect of this application provides a temperature measuring device, including: a first conveying unit 1, which receives and carries a top-open smoke box to be inspected; a temperature acquisition unit 2, which is located above the first conveying unit 1, and the outer peripheral surface of the temperature acquisition unit 2 is covered with a protective structure; and a first driving assembly 3, which is connected to the temperature acquisition unit 2 and is used to drive the temperature acquisition unit 2 to move up and down in a vertical direction. The temperature acquisition unit 2 is inserted into the smoke box to be inspected located on the first conveying unit 1 under the drive of the first driving assembly 3 to collect temperature data of the smoke inside the smoke box.

[0046] In this embodiment, the first conveying unit 1 can orderly receive and carry the tobacco boxes to be inspected, and cooperate with the first driving component 3 to drive the temperature acquisition unit 2 to automatically lift and insert into the tobacco boxes to be inspected, forming an automated inspection process. Compared with the traditional manual inspection method, this automated operation can inspect more tobacco boxes to be inspected per unit time, greatly improving inspection efficiency. At the same time, the temperature acquisition unit 2 can directly insert into the inside of the tobacco box to collect the temperature of the tobacco flakes. Compared with the traditional method of manually cutting the packing straps to open the tobacco boxes to be inspected, this not only avoids the waste of packing straps, but also fundamentally improves the accuracy of the inspection results. It should be noted that the traditional manual inspection method requires quality inspectors to cut the packing straps to open the tobacco boxes to be inspected, and use a hammer and steel cone to make holes before inserting a thermometer to measure the temperature. However, there are many unstable factors in the manual operation process, such as the rapid influx of outside air when the tobacco boxes to be inspected are opened, the airflow disturbance inside the tobacco boxes to be inspected caused by the drilling operation, and the inaccuracy of manually placing the thermometer. These will inevitably change the original temperature state of the tobacco flakes inside the tobacco boxes to be inspected, resulting in a large deviation in the measurement results. This temperature measuring device measures the temperature of the open-topped tobacco boxes before they are transported to the packing section. The entire process requires no manual intervention, such as cutting the packing straps. Under the precise drive of the first drive assembly 3, the temperature acquisition unit 2 smoothly inserts into the tobacco box, directly collecting data in the naturally stable temperature environment of the tobacco. This minimizes interference from external factors, ensuring that the collected temperature data accurately reflects the actual temperature of the tobacco. Furthermore, the protective structure covering the outer surface of the temperature acquisition unit 2 further enhances the accuracy of the test results. It effectively prevents dust, moisture, and other impurities from the tobacco production and storage environment from contacting the temperature acquisition unit 2, avoiding any impact on heat conduction and temperature sensing sensitivity due to impurities. This further guarantees the accuracy and stability of the data acquired by the temperature acquisition unit 2, making this temperature measuring device far superior to traditional manual testing methods in terms of accuracy, providing solid and reliable technical support for precise control of tobacco quality.

[0047] The first conveying unit 1 is used to receive and carry the smoke box to be inspected with its top open, providing a stable smoke box carrying platform for subsequent temperature measurement operations and ensuring that the smoke box to be inspected is fixed and accurate in position during the inspection process.

[0048] Specifically, the first conveying unit 1 has a rolling bearing structure, such as rollers, to facilitate receiving the conveyed cigarette boxes to be inspected.

[0049] The temperature acquisition unit 2 is positioned above the first conveying unit 1, which facilitates its smooth contact with the smoke box to be inspected carried on the first conveying unit 1 below.

[0050] Specifically, the temperature acquisition unit 2 can be a thermocouple temperature probe, with its outer peripheral surface covered by a protective structure to form an armored thermocouple temperature probe. In practical applications, the protective structure covers the outer surface of the temperature-sensitive element and extends along the axial direction of the temperature-sensitive element to form a continuous covering shape, so as to protect the temperature acquisition unit 2 from physical impacts, chemical corrosion, water vapor penetration, and other adverse factors from the external environment that may affect its normal operation and performance stability. This ensures that the temperature acquisition unit 2 can accurately sense temperature changes under various complex operating conditions and convert them into corresponding measurable signals.

[0051] The first driving component 3 is connected to the temperature acquisition unit 2, and the first driving component 3 is used to drive the temperature acquisition unit 2 to move up and down in the vertical direction. In practical applications, the temperature acquisition unit 2, driven by the first driving component 3, is precisely and smoothly inserted into the tobacco box to be inspected located on the first conveying unit 1, thereby realizing the acquisition of temperature data of the tobacco in the tobacco box to be inspected, and ensuring that the acquired temperature data can truly and accurately reflect the actual temperature state of the tobacco.

[0052] Specifically, in practical applications, when the smoke box to be inspected is transported to the designated detection position by the first conveying unit 1, such as directly below the temperature acquisition unit 2, the first driving component 3 begins to function, precisely controlling the temperature acquisition unit 2 to descend vertically, so that the temperature acquisition unit 2 can be smoothly and accurately inserted into the smoke box to be inspected located on the first conveying unit 1, thereby completing the collection of tobacco temperature data inside the smoke box to be inspected.

[0053] In the above embodiments, see Figure 1 As shown, the first driving component 3 includes: a first bracket 31; a first driving unit 32, which is mounted on the first bracket 31 and whose output is connected to the temperature acquisition unit 2; and a first sensing unit 33, which is mounted on the first bracket 31 and is used to sense the position information of the smoke box to be inspected.

[0054] The first bracket 31 can be a gate-shaped structure, which is the basic structural part of the first drive component 3 and plays a role in providing stable support for other components.

[0055] Specifically, in practical applications, the first bracket 31 spans the first conveying unit 1, providing a stable mounting platform for the entire first drive assembly 3, ensuring that the first drive unit 32 and the first sensing unit 33 can accurately perform their respective functions. During the long-term operation of the temperature measuring device, the relative positions of each component can be maintained, avoiding the impact on the accuracy of temperature acquisition due to equipment shaking or component displacement.

[0056] The first drive unit 32 can be a cylinder.

[0057] Specifically, in practical applications, the first drive unit 32 is mounted on the first bracket 31, and its output end is connected to the temperature acquisition unit 2, enabling precise control of the vertical lifting and lowering movement of the temperature acquisition unit 2. Through the precise drive of the first drive unit 32, the positional accuracy and movement stability of the temperature acquisition unit 2 when inserted into the tobacco box to be inspected can be ensured. Compared with manual operation, this precise control can minimize interference from the original temperature state of the tobacco in the tobacco box to be inspected. For example, during manual inspection, it is difficult to ensure that the thermometer is inserted into the tobacco box to be inspected at the same depth and position each time. However, the first drive unit 32 can, according to a preset program, allow the temperature acquisition unit 2 to be inserted into each tobacco box to be inspected in the same way and at the same depth, thereby improving the consistency and accuracy of temperature acquisition.

[0058] The first sensing unit 33 can be an active infrared sensor, including an infrared emitter and an infrared receiver. The infrared emitter emits an infrared beam of a specific frequency. When the smoke box to be inspected enters the beam path, it will reflect, refract, or block the beam. As a result, the infrared signal received by the infrared receiver will change, thereby determining the position of the smoke box to be inspected.

[0059] Specifically, the first sensing unit 33 is mounted on the first bracket 31, with its detection end facing the first conveying unit 1. When the smoke box to be inspected is conveyed by the first conveying unit 1 to the designated detection position, such as directly below the temperature acquisition unit 2, the first sensing unit 33 can detect this information in a timely and accurate manner and transmit the signal to other control units (such as the first drive unit 32), thereby triggering the descent action of the temperature acquisition unit 2.

[0060] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 and Figure 3As shown, the temperature measuring device also includes a second drive assembly 4, which is located on top of the first bracket 31. The second drive assembly 4 is connected to the first drive unit 32 and is used to drive the first drive unit 32 to move up and down.

[0061] It should be noted that in practical applications, the specifications (such as height and shape) of the smoke boxes to be inspected may vary. The second drive assembly 4 drives the first drive unit 32 to rise and fall, enabling the temperature acquisition unit 2 to better adapt to smoke boxes of different heights. For example, when encountering a tall smoke box, the second drive assembly 4 can raise the first drive unit 32 and the connected temperature acquisition unit 2 to a suitable height, and then drive the temperature acquisition unit 2 to fall and insert it into the smoke box to collect temperature data. For shorter smoke boxes, the height can be adjusted accordingly to ensure that the temperature acquisition unit 2 can accurately reach the appropriate position inside the smoke box for detection.

[0062] The second drive assembly 4 is located at the top of the first bracket 31. The first bracket 31 serves as the support structure for the entire first drive assembly 3 and also provides a mounting base for the second drive assembly 4. This position places the second drive assembly 4 at a relatively high level, facilitating its operation of the first drive unit 32 below. It should be noted that when the first bracket 31 has a U-shaped structure, the second drive assembly 4 is mounted on the crossbeam of the first bracket 31. In this case, the crossbeam of the first bracket 31 has through holes to allow the first drive unit 32 to move up and down.

[0063] The second drive assembly 4 is connected to the first drive unit 32. This connection allows the second drive assembly 4 to transmit power to the first drive unit 32, thereby controlling the lifting and lowering of the first drive unit 32. For example, the connection can be made through mechanical linkages, lead screws, hydraulic or pneumatic pipes, depending on the type of the second drive assembly 4 (such as an electric actuator, hydraulic actuator, or pneumatic device).

[0064] Specifically, the main function of the second drive assembly 4 is to drive the first drive unit 32 to rise and fall. When the second drive assembly 4 receives a control signal (this signal can come from the control system of the temperature measuring device, which sends signals according to a preset program or operator instructions), the second drive assembly 4 will generate corresponding power output. If the second drive assembly 4 is an electric push rod, when it receives an upward signal, the motor inside the electric push rod drives the lead screw to rotate, and the nut on the lead screw (connected to the first drive unit 32) will move upward along the lead screw, thereby driving the first drive unit 32 to rise; conversely, when it receives a downward signal, the nut will move downward, causing the first drive unit 32 to fall. It can be understood that by controlling the rise and fall of the first drive unit 32, the starting position of the temperature acquisition unit 2 is indirectly adjusted. For example, when facing tobacco boxes of different heights, the second drive assembly 4 can first raise or lower the first drive unit 32 to a suitable height, and then the first drive unit 32 drives the temperature acquisition unit 2 to descend vertically and insert into the appropriate position in the tobacco box for temperature acquisition. This ensures that the temperature acquisition unit 2 can adapt to tobacco boxes of various heights and accurately obtain the temperature data of the tobacco inside.

[0065] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, the temperature measuring device also includes: a positioning tube 5, which surrounds the outer periphery of the temperature acquisition unit 2, and moves synchronously with the first driving unit 32; a positioning plate 6, which is located at one end of the positioning tube 5 near the smoke box to be inspected, and has a clearance hole at the center of the positioning plate 6 that passes through the temperature acquisition unit 2. The positioning plate 6 is used to cooperate with the positioning tube 5 to press the tobacco flakes in the smoke box to be inspected under the drive of the second driving component 4.

[0066] The positioning tube 5 is hollow and open at both ends. In practical applications, the positioning tube 5 is located at the end of the first drive unit 32 near the first conveying unit 1. The positioning tube 5 is fixedly connected to the outer shell of the first drive unit 32. The temperature acquisition unit 2 is inserted into the positioning tube 5 and connected to the output end of the first drive unit 32.

[0067] Specifically, the positioning tube 5 moves synchronously with the first drive unit 32, which is equivalent to providing a precise guide for the temperature acquisition unit 2. When the temperature acquisition unit 2 is inserted into the tobacco box to be inspected under the drive of the first drive unit 32, the positioning tube 5 ensures that the temperature acquisition unit 2 is inserted vertically and accurately into the tobacco box. It's like installing a "track" for the temperature acquisition unit 2, preventing it from shifting or shaking during descent, thus ensuring that the temperature acquisition unit 2 can accurately reach the predetermined detection position of the tobacco in the tobacco box, improving the positional accuracy of temperature acquisition.

[0068] The positioning tube 5 has a positioning plate 6 at its end near the tobacco box to be inspected. The positioning plate 6 is a component that cooperates with the positioning tube 5. There is a clearance hole in the center of the positioning plate 6, which is specifically designed for the temperature acquisition unit 2 to pass through. This is analogous to making a hole in a wall, the size of which is just large enough for the temperature acquisition unit 2 to pass through, while the rest of the positioning plate 6 plays an auxiliary role. In practical application, when the second drive assembly 4 starts working, the positioning tube 5 will be driven by it to move the positioning plate 6 towards the tobacco box to be inspected until the positioning plate 6 contacts and presses against the tobacco in the tobacco box.

[0069] Specifically, the positioning plate 6, driven by the second drive assembly 4, presses the tobacco leaves in the tobacco box to be inspected, making them more compact. During tobacco storage, the tobacco leaves may be relatively loose, leading to uneven temperature distribution. Compacting the tobacco leaves reduces the air gaps inside, resulting in more uniform heat transfer and allowing the temperature acquisition unit 2 to obtain temperature data that better represents the overall state of the tobacco leaves. Understandably, the compacted tobacco leaves have a closer contact with the temperature acquisition unit 2, reducing temperature measurement errors caused by poor contact. For example, when the tobacco leaves are loose, the temperature acquisition unit 2 may only contact the surface part of the tobacco leaves, failing to accurately obtain the true internal temperature; however, after compaction, the temperature acquisition unit 2 can better sense the heat conduction within the tobacco leaves, thereby improving the accuracy of temperature acquisition.

[0070] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 As shown, the positioning tube 5 is an elastic structure. The positioning tube 5 can be compressed along the axial direction of the positioning tube 5. When the second driving component 4 drives the first driving unit 32 to descend, the first driving unit 32 can drive the positioning plate 6 to move downward through the positioning tube 5, so that the positioning plate 6 comes into contact with the tobacco flakes in the tobacco box to be inspected and gradually applies pressure, thereby pressing and fixing the tobacco flakes.

[0071] Here, the positioning tube 5 is an elastic structure that can be compressed axially. This allows the positioning tube 5 to adaptively adjust according to the actual height and compaction of the tobacco sheets during the pressing process. For example, when the tobacco sheets in the inspection box are loosely piled and relatively high, the positioning tube 5 can be gradually compressed during its descent, allowing the positioning plate 6 to slowly contact the tobacco sheets and gradually apply pressure, avoiding chaotic distribution of the tobacco sheets due to sudden, forceful compression. Simultaneously, the elastic positioning tube 5 buffers pressure during the pressing process, preventing excessive compression and damage to the tobacco sheets. Tobacco sheets are relatively fragile; excessive pressure may cause them to break or deform, affecting their internal temperature distribution and subsequent detection accuracy. The elastic positioning tube 5 acts like a "buffer," ensuring the tobacco sheets are pressed tightly while minimizing damage to their physical structure and maintaining their integrity.

[0072] The positioning tube 5 can include a rigid section and a flexible section. The rigid section can be made of high-strength metal materials, such as aluminum alloy or stainless steel. Its function is to provide a stable support structure for the entire positioning tube 5, ensuring that the overall shape of the positioning tube 5 remains relatively fixed during the lifting and lowering of the temperature acquisition unit 2, preventing excessive bending or deformation from affecting the accuracy and stability of temperature acquisition. The flexible section is made of materials with good elasticity and flexibility, such as springs or high-temperature resistant rubber or silicone. Its main function is to realize the axial compression characteristics of the positioning tube 5. When the second drive assembly 4 drives the first drive unit 32 to descend, the flexible section can undergo elastic deformation under pressure, thereby driving the positioning plate 6 to move downward and gradually apply pressure to the tobacco. Moreover, the elasticity of the flexible section can also play a buffering role, avoiding damage to the tobacco due to sudden impact, ensuring that the tobacco maintains its integrity during the process of being compressed and fixed, and thus ensuring that the temperature data acquired by the temperature acquisition unit 2 can truly reflect the actual temperature state of the tobacco.

[0073] Specifically, the flexible segment consists of two sections, with a rigid segment located between them. The two flexible segments are used to connect the outer shell of the first drive unit 32 and the positioning plate 6, respectively. In practical applications, the flexible segment at the top of the rigid segment connects to the outer shell of the first drive unit 32, while the flexible segment at the bottom of the rigid segment connects to the positioning plate 6.

[0074] In the above embodiments, see Figure 3 As shown, the second drive assembly 4 includes: a second bracket 41, which is disposed on top of the first bracket 31, and a movable plate 44 is movably disposed on the second bracket 41 in the vertical direction, and the first drive unit 32 is connected to the movable plate 44; and a second drive unit 42, which is connected to the movable plate 44 through a transmission part 43, and is used to drive the transmission part 43 to move, so as to drive the first drive unit 32 to rise and fall through the transmission part 43.

[0075] The second support 41 can also be a gate-shaped structure.

[0076] Specifically, the second bracket 41 is fixedly mounted on the crossbeam of the first bracket 31. The second bracket 41 is the basic support structure of the entire second drive assembly 4, which is used to ensure the stability of the entire second drive assembly 4 in space, so that subsequent driving and transmission actions can be carried out within a relatively fixed frame.

[0077] In practical applications, the second support 41 provides a track and space for the movable plate 44 to move. The movable plate 44 is slidably mounted on the two columns of the second support 41, so that the movable plate 44 can only move in the vertical direction, ensuring the directionality and accuracy of the movement of the movable plate 44.

[0078] Specifically, in practical applications, the movable plate 44 acts as an intermediary. The first drive unit 32 is fixed relative to the movable plate 44, which connects the first drive unit 32 and the second drive unit 42 via the transmission part 43. When the movable plate 44 moves, it drives the first drive unit 32 to rise and fall together.

[0079] The second drive unit 42 is the power source, generating power to drive the transmission unit 43. In practical applications, the second drive unit 42 can be different types of power equipment such as an electric motor, a hydraulic pump, or a pneumatic device. For example, if the second drive unit 42 is an electric motor, it can output torque through a rotating shaft; if it is a hydraulic pump, it can provide power through the pressure of output hydraulic oil.

[0080] The transmission unit 43 connects the second drive unit 42 and the movable plate 44, transmitting power from the second drive unit 42 to the movable plate 44, thereby driving the first drive unit 32 to rise and fall. The transmission unit 43 can take various forms, such as screw drive, chain drive, belt drive, or hydraulic drive. Taking screw drive as an example, the output shaft of the second drive unit 42 is connected to the screw. When the second drive unit 42 operates, the screw rotates. A nut that mates with the screw is fixed on the movable plate 44. The rotation of the screw causes the nut (i.e., the movable plate 44) to move up and down along the screw, thus driving the first drive unit 32 to rise and fall. In the case of hydraulic drive, the second drive unit 42 (hydraulic pump) delivers hydraulic oil through pipes to a hydraulic cylinder connected to the movable plate 44. By controlling the pressure and flow rate of the hydraulic oil, the piston in the cylinder (connected to the movable plate 44) moves, thereby achieving the rising and falling of the first drive unit 32.

[0081] See Figure 4As shown, an embodiment of the second aspect of this application provides a cigarette box conveying system, including: a temperature measuring device as described in any of the above; and a re-weighing device 7, which is disposed upstream of the temperature measuring device along the conveying direction of the cigarette box to be inspected, and is used to perform a second weighing of the cigarette box to be inspected.

[0082] In this embodiment, by setting a re-weighing device 7 on the upstream side of the conveying direction of the smoke box to be inspected, the smoke box to be inspected can be re-weighed without leaving the track, avoiding frequent contact and handling operations between the forklift and the smoke box to be inspected, reducing operational safety risks and manual transportation costs.

[0083] It should be noted that in conventional production scenarios, weighing cigarette boxes to be inspected usually requires the use of forklifts or similar tools to move the boxes to specialized weighing equipment. In this embodiment, by installing a re-weighing device 7 upstream of the cigarette box's conveying direction, the cigarette box can be re-weighed without leaving the track. In other words, as the cigarette box travels normally along the conveying track, upon reaching the re-weighing device 7, it can be weighed directly on the track without leaving the original conveying track, unlike traditional methods. This avoids frequent contact and handling between the forklift and the cigarette box, reducing operational safety risks and labor transportation costs.

[0084] In the above embodiment, the weighing device 7 includes: a second conveying unit for receiving the smoke box to be inspected from the upstream process and transferring the smoke box to be inspected to the temperature measuring device; and a rail scale, which is set along the conveying path of the second conveying unit and is used to measure the weight data of the smoke box to be inspected located on the second conveying unit.

[0085] Here, the track scale is positioned along the conveying path of the second conveying unit, enabling real-time measurement of the weight of the cigarette boxes as they are transported normally. The second conveying unit receives cigarette boxes from upstream processes and transfers them to the temperature measuring device, ensuring the continuity of the cigarette box transport. The entire process is a seamless assembly line operation. The cigarette boxes do not need to stop at the weighing stage; they are weighed while being transported, significantly improving production efficiency.

[0086] The primary function of the second conveying unit is to receive cigarette boxes awaiting inspection from upstream processes. In the tobacco production chain, each process is interconnected. After the upstream process completes the preliminary processing or filling of the cigarette boxes, they are transferred to the re-weighing device 7. The second conveying unit acts like a relay race, receiving these boxes at this handover point. Specifically, the second conveying unit can take various forms, such as a conveyor belt, chain conveyor, or roller conveyor. For example, if the second conveying unit is a conveyor belt, it uses friction to smoothly transfer the cigarette boxes from the upstream conveying equipment onto its own conveyor belt, thus receiving them. The next step after receiving them is to move the cigarette boxes to the temperature measuring device, ensuring the continuous flow of the cigarette boxes on the production line and maintaining the continuity of the entire production process. During the transfer process, the second conveying unit can transport the cigarette boxes at a stable speed and in a suitable manner. For example, the conveying speed can be adjusted by controlling the motor speed of the second conveying unit to match the operating speed of the upstream and downstream equipment, ensuring that the cigarette boxes to be inspected will not accumulate during the conveying process, nor will they fall or be damaged due to excessive speed. Moreover, the transfer process is automated, requiring minimal human intervention, thus reducing labor costs and potential errors caused by manual operation.

[0087] Specifically, in practical applications, the rail scale can be installed below the bracket of the second conveying unit or embedded inside the conveying track of the second conveying unit. For example, when the rail scale is embedded, the weighing sensor of the rail scale is installed in the structure of the conveying track of the second conveying unit, and the weight of the tobacco box to be inspected can be directly sensed when it passes through this position.

[0088] In some possible implementations disclosed in this application, participants Figure 4 As shown, the cigarette box conveying system also includes a rotary conveyor 8, which is located between the weighing device 7 and the temperature measuring device along the conveying direction of the cigarette box to be inspected. The rotary conveyor 8 is used to control the rotation of the cigarette box to be inspected.

[0089] Here, by setting up a rotary conveyor device 8, the conveying path of the smoke box to be inspected can be arranged more flexibly.

[0090] Among them, the rotary conveyor 8 can be a roller-type rotary conveyor 8.

[0091] Specifically, in practical applications, the cigarette box to be inspected is placed on the rollers of the rotary conveyor 8. When a change of direction is required, the control system adjusts the rotation direction and speed of a specific roller. For example, on one side of the cigarette box to be inspected, the roller rotates forward, while on the other side, the roller rotates backward. This causes the cigarette box to rotate on the roller, achieving the change of direction. After the change of direction is completed, the roller continues to rotate in the normal direction, conveying the cigarette box to be inspected to the next stage.

[0092] In some possible implementations disclosed in this application, participants Figure 4 As shown, the cigarette box conveying system also includes a rail trolley, which is set downstream of the temperature measuring device along the conveying direction of the cigarette boxes to be inspected. The rail trolley is used to transport the inspected cigarette boxes to different subsequent processing areas according to predetermined classification rules.

[0093] Here, the tracked trolley, as an automated handling device, effectively controls its speed and accuracy, enabling the rapid transport of inspected cigarette boxes from downstream of the temperature measuring device to the corresponding subsequent processing area, reducing the time and labor intensity of manual handling. Simultaneously, the tracked trolley seamlessly connects the inspection and subsequent processing steps. Tobacco production is a complex assembly line operation, and the close coordination between different processes is crucial for overall production efficiency. The tracked trolley ensures a smooth transition of cigarette boxes from the temperature detection stage to subsequent stages such as packaging and warehousing, reducing process interruptions caused by untimely or chaotic handling and improving the overall operational efficiency of the production system.

[0094] In some possible embodiments disclosed in this application, the smoke box conveying system further includes a control device, which is electrically connected to the temperature measuring device and the weighing device 7, respectively.

[0095] Here, the control device is equivalent to the control system mentioned above, enabling automated control of the cigarette box conveying system. Specifically, the control device can automatically adjust the working status of the temperature measuring device and the re-weighing device 7 according to preset programs and rules. For example, when a batch of cigarette boxes begins to be conveyed, the control device can automatically activate the re-weighing device 7 to weigh the cigarettes, and then determine whether to activate the temperature measuring device for temperature detection based on the weight data. Throughout the entire process, minimal manual intervention is required, significantly improving production efficiency.

[0096] Specifically, in practical applications, the control device can be an industrial computer or a PLC, etc.

The above are merely preferred embodiments of this application.
