[0002] Box-type tobacco storage is a method of storing tobacco shreds that offers advantages such as improved storage environment and reduced risk of tobacco insect infestation. Therefore, it is widely adopted in the cigarette manufacturing industry. The process of box-type tobacco storage includes mixing, packing, box storage, box turning and unloading, and buffer feeding. The tobacco box is a crucial storage and turnover device in this process. However, during box turning and unloading, some tobacco shreds may remain in the box. If these shreds remain in the box for a long time, tobacco insects can easily breed, affecting the quality of tobacco storage. Therefore, the tobacco box needs to be cleaned to ensure no tobacco shreds remain.

[0003] An existing tobacco box cleaning device uses a flipping mechanism to invert the tobacco box onto the cleaning device, and then uses a brush and nozzle to clean the inner wall of the tobacco box. However, tobacco residue remains along the upper edge of the box during the process of the tobacco box moving around. This cleaning device can only clean the inner wall of the tobacco box and cannot clean the tobacco residue along the upper edge. Over time, this residue will accumulate between the lid and the body of the tobacco box, forming tobacco grime, affecting the storage seal of the tobacco box, and posing a risk of tobacco insect infestation.

[0029] On the one hand, please refer to Figures 1 to 5 This embodiment provides a cleaning device, including a cleaning brush 1, a nozzle 2, and a frame 3. The cleaning brush 1 is used to clean the bottom surface of the inner cavity of the box to be cleaned, and the nozzle 2 is used to spray cleaning medium onto the inner wall of the box to be cleaned. The cleaning device also includes a guide brush 4 and a drive mechanism 5. The guide brush 4 is used to clean the upper edge of the box to be cleaned. The guide brush 4 is fixed in position relative to the frame 3 and extends along a first direction. The drive mechanism 5 is used to drive one of the box to be cleaned and the guide brush 4 to move relative to the other of the box to be cleaned along a second direction. The first and second directions are angled. Preferably, the first and second directions are perpendicular. With this configuration, when the drive mechanism 5 drives one of the box to be cleaned and the guide brush 4 to move relative to the other of the box to be cleaned along the second direction, the guide brush 4 can clean the upper edge of the box to be cleaned, reducing cleaning dead zones in the cleaning device.

[0030] Specifically, the cleaning medium is a cleaning gas. During cleaning, the box to be cleaned is inverted onto the cleaning brush 1 via the drive mechanism 5. The cleaning brush 1 cleans the bottom surface of the inner cavity of the box, while the nozzle 2 sprays cleaning gas to blow away tobacco or impurities from the side walls of the inner cavity. Through the relative movement of the brush 4 and the box to be cleaned, the brush 4 cleans the upper edge of the box. In other embodiments, the cleaning medium can also be a cleaning liquid.

[0031] Alternatively, please refer to Figure 1 The cleaning device also includes a guide rail 6 and a carriage 7. The guide rail 6 extends along a first direction and is fixed relative to the frame 3. The carriage 7 is slidably connected to the guide rail 6, and the cleaning brush 1 is rotatably connected to the carriage 7. With this configuration, the guide rail 6 provides support and guidance for the carriage 7, while the cleaning brush 1 is rotatably connected to the carriage 7. When the carriage 7 slides relative to the guide rail, the cleaning brush 1 can also slide relative to the guide rail, facilitating the cleaning brush 1 to clean the cleaning box along the first direction.

[0032] Alternatively, please refer to Figure 1 and Figure 2The cleaning device includes multiple cleaning brushes 1, which are arranged along the length of the guide rail 6 and rotatably connected to the carriage 7. This arrangement allows the multiple cleaning brushes 1 to simultaneously clean the bottom surface of the inner cavity of the box to be cleaned, improving the cleaning efficiency of the cleaning device. Preferably, the effective cleaning ranges of any two adjacent cleaning brushes 1 are connected or overlap, avoiding gaps in the cleaning ranges of adjacent cleaning brushes 1 that could create cleaning dead corners on the bottom surface of the inner cavity of the box.

[0033] Optionally, any two adjacent cleaning brushes 1 are configured to rotate in opposite directions. This configuration allows the cleaning brushes 1 rotating in different directions to clean from different angles, reducing cleaning dead zones. Simultaneously, the opposite rotation of any two adjacent cleaning brushes 1 generates friction between them, thereby removing impurities entangled or attached to the adjacent brushes 1, preventing long-term dirt accumulation, and extending the service life of the cleaning brushes 1.

[0034] Alternatively, please refer to Figure 2 The cleaning device includes multiple nozzles 2, with a nozzle 2 positioned between any two adjacent cleaning brushes 1. This arrangement allows multiple nozzles 2 to spray cleaning media simultaneously, increasing the cleaning range of the nozzles 2 and improving the cleaning efficiency of the cleaning device.

[0035] Alternatively, please refer to Figure 4 All nozzles 2 are rotating nozzles 2. This configuration allows the rotating nozzles 2 to cover a wider area, ensuring that the cleaning medium reaches hard-to-reach corners and surfaces. At the same time, the rotating nozzles 2 help to evenly distribute the cleaning medium on the inner wall of the chamber to be cleaned, reducing cleaning dead spots and improving cleaning quality.

[0036] Alternatively, please refer to Figure 2 and Figure 3 The cleaning device includes a drive motor 8, a base 9, and multiple gearboxes 10. The drive motor 8 and the gearboxes 10 are all fixed to the base 9. Each gearbox 10 is connected to a corresponding cleaning brush 1, and the gearboxes 10 are sequentially connected. One of the gearboxes 10 is also connected to the motor, enabling the drive motor 8 to drive the multiple cleaning brushes 1 to rotate. This configuration ensures that all cleaning brushes 1 are driven by the same drive motor 8, guaranteeing uniform power output and consistent cleaning results. Furthermore, this configuration simplifies the structure of the cleaning device, facilitates its arrangement and assembly, and reduces manufacturing costs.

[0037] Specifically, the gearbox 10 includes a housing, an input bevel gear, an output bevel gear, a drive shaft, and a transmission bevel gear. The drive shaft is rotatably connected to the housing, and the drive shaft is fixedly connected to the input bevel gear. The input bevel gear meshes with the output bevel gear, and the output bevel gear is fixedly connected to the cleaning brush 1. The output bevel gear meshes with the transmission bevel gear, and the transmission bevel gear is coaxial with and opposite to the input bevel gear. For two adjacent gearboxes 10, the drive shaft of one gearbox 10 is fixedly connected to the input bevel gear of the other gearbox 10. The drive motor 8 is connected to the drive shaft of one of the gearboxes 10.

[0038] Optionally, the cleaning device further includes a telescopic drive component 11, which is connected to the base 9 via a transmission connection, and the telescopic drive component 11 can drive the base 9 to reciprocate along a first direction. With this configuration, the telescopic drive component 11 drives the base 9 to reciprocate along the first direction, thereby driving multiple cleaning brushes 1 to reciprocate along the first direction to clean the bottom surface of the inner cavity of the cleaning box, thus increasing the cleaning range of the cleaning brushes 1, reducing cleaning dead angles, and improving cleaning efficiency. Specifically, the telescopic drive component 11 is a pneumatic cylinder or a hydraulic cylinder.

[0039] Alternatively, please refer to Figure 1 , Figure 3 and Figure 5 The cleaning device also includes a collection hopper 12, a receiving conveyor belt, and a receiving box 14. The box to be cleaned can be inverted in the collection hopper 12. The lower end of the collection hopper 12 is provided with a discharge port 121.

The receiving conveyor belt is used to transport the residual material falling from the discharge port 121 to the receiving box 14. With this arrangement, the residual material after cleaning can fall from the discharge port 121 and be transported to the receiving box 14 by the receiving conveyor belt, thereby recovering the residual material, avoiding the accumulation of residual material after cleaning and blocking the equipment, and improving the material recovery rate.

[0040] On the other hand, please refer to Figure 5This invention provides a tobacco box cleaning system, including a box to be cleaned, a feeding conveyor belt, a discharging conveyor belt, and a cleaning device according to any of the above technical solutions. The box to be cleaned is a tobacco box 17. The feeding conveyor belt is used to transport the tobacco box 17 with its opening facing upwards to the loading station. The driving mechanism 5 is a box-turning machine, which can grab the tobacco box 17 from the loading station and turn the tobacco box 17 so that its opening faces downwards. The box-turning machine drives the tobacco box 17 to move in a second direction. The discharging conveyor belt is used to transport the tobacco box 17 after it has been cleaned by the cleaning device. Specifically, the tobacco box 17 is used for storing or transporting tobacco shreds. After use, tobacco shred residue or even dirt easily accumulates on the upper edge of the tobacco box 17. If it is not cleaned for a long time, it will affect the sealing of the tobacco box 17 and may even breed tobacco insects, affecting the quality of the tobacco shreds. The tobacco box 17 cleaning system uses a flipping machine to turn the tobacco box 17 so that the opening faces downwards, and moves the tobacco box 17 in a second direction to cooperate with the brush 4 to clean the upper edge of the tobacco box 17, preventing tobacco from accumulating on the upper edge of the tobacco box 17, which would affect the storage seal of the tobacco box 17 or breed tobacco insects. The flipping machine is existing technology, and its specific structure will not be described in detail here.

[0041] The working principle of this smoke box cleaning system is as follows:

[0042] The feeding conveyor belt transports the cigarette box 17 with its opening facing upwards to the loading station. The flipping machine grabs the cigarette box 17 from the loading station and flips it so that its opening faces downwards. It then moves the cigarette box 17 above the cleaning device and places it upside down on the cleaning brush 1. Multiple rotating nozzles 2 spray cleaning gas to blow away tobacco or impurities from the inner wall of the cigarette box 17. The telescopic drive 11 drives the cleaning brush 1 to move the cigarette box 17 back and forth along the first direction for one side length. Then, the flipping machine moves the cigarette box 17 along the second direction. When the flipping machine has moved the cigarette box 17 a distance along the second direction for one side length, the bottom surface of the inner cavity of the cigarette box 17 has been completely swept by the cleaning brush 1. At the same time, as the flipping machine moves the cigarette box 17 along the second direction, the brush 4 set along the first direction cleans the upper edge of the cigarette box 17. The flipping machine flips the cleaned cigarette box 17 so that its opening faces upwards and moves it to the unloading conveyor belt.
