[0028] To resolve the above issues, please refer to [link / reference]. Figures 1 to 5This utility model provides an automatic cleaning device for empty tobacco boxes, used for cleaning the body of a flipped tobacco box. It includes a lifting assembly 1, an air jet assembly 2, and a proximity switch 3. The lifting assembly 1 is driven and connected to the air jet assembly 2, causing the air jet assembly 2 to move along the height of the box. The air jet assembly 2 includes four sets of air jets 21 and an air pump 22. The four air jets 21 are arranged in a circumferential array around the driving end of the lifting assembly 1 and connected to the air pump 22 via an air supply pipe 23. Each air jet 21 includes a first spray bar 211 and a second spray bar. The first spray bar 211 has a first air outlet 213 on its circumference for cleaning the inner surface of the box. The second spray bar has a second air outlet 214 facing the inner corner of the box for cleaning the inner corner. The proximity switch 3 is located on the surface of the air jet assembly 2 away from the lifting assembly 1 and is used to measure the distance between the air jet assembly 2 and the inner bottom surface of the box.

[0029] In optional embodiments, such as Figure 1 As shown, the jet assembly 2 also includes a mounting bracket 24, which has an "X" shaped structure. A limiting post 241 is provided at the end of the mounting bracket 24, and the jet component 21 is connected to the limiting post. The mounting bracket 24, facing away from the center surface of the jet component 21, is connected to the drive end of the lifting assembly 1. Specifically, the mounting bracket 24 is designed to correspond to the housing, allowing the second spray bar to be closer to the inner corner of the housing, facilitating the second spray bar's cleaning of the inner corner and preventing tobacco residue from remaining there.

[0030] In optional embodiments, such as Figure 5 As shown, the air supply pipe 23 is sequentially installed through the mounting bracket 24 and the limiting post, and communicates with the jet component. Compressed air in the air pump 22 is transported to the jet assembly 2 through the air supply pipe 23, providing sufficient airflow and purging speed, facilitating continuous cleaning of the housing by the jet assembly 2, and improving the cleaning efficiency and quality of the housing by the jet assembly 2.

[0031] In optional embodiments, such as Figure 1 As shown, the driving end of the lifting assembly 1 is provided with a connecting part 11, and the mounting bracket 24 is threadedly connected to the connecting part 11.

[0032] In optional embodiments, such as Figure 1As shown, the jet component 21 further includes a central component 212. The first spray bar 211 and the second spray bar are disposed around the central component 212 and communicate with the central component 212. The central component 212 is connected to the limiting post. The outlet end of the air supply pipe 23 communicates with the central component 212, forming a passage between the air supply pipe 23 and the first spray bar 211 and the second spray bar. Specifically, the central component 212 has a hollow structure. After compressed air enters the central component 212 through the air supply pipe 23, it evenly distributes the air into the first spray bar 211 and the second spray bar, achieving the effect of uniform air output.

[0033] In optional embodiments, such as Figure 2 As shown, the second spray bar includes a bar body 215 and a nozzle 216. One end of the bar body 215 is connected to the central component 212, and the other end is connected to the nozzle 216. The nozzle 216 and the bar body 215 are set at an angle, corresponding to the inner fold angle of the housing. Specifically, the length of the second spray bar is greater than that of the first spray bar 211, so that the nozzle 216 is close to the inner fold angle to specifically clean the inner fold angle, quickly cleaning the tobacco leaves stuck in the inner fold angle, improving the efficiency and cleanliness of cleaning dead corners.

[0034] In optional embodiments, such as Figure 4 As shown, the lifting assembly 1 includes a lifting cylinder 12 and a telescopic rod 13. One end of the telescopic rod 13 is driven and connected to the lifting cylinder 12, and the other end is provided with the connecting part 11. Specifically, the lifting cylinder 12 is installed on the ground isolation plate to achieve stable installation of the lifting cylinder 12. The diameter of the connecting part 11 is larger than the diameter of the end of the telescopic rod 13, increasing the connection surface between the telescopic rod 13 and the mounting bracket 24, thus achieving a stable connection between the two. The center of the mounting bracket 24 is threaded to the connecting part 11, achieving a detachable connection between the two, which facilitates disassembly, maintenance, and replacement by workers.

[0035] In optional embodiments, such as Figure 2 As shown, the first air outlet 213 is distributed along the length of the first spray bar 211, and there are three rows of the first air outlet 213. Specifically, each row has four first air outlets 213, and the three rows of first air outlets 213 face different directions on the inner surface of the box, realizing large-area cleaning and enabling rapid cleaning of the inside of the box.

[0036] In optional embodiments, such as Figure 1As shown, it also includes a dust collection box 4, which is disposed around the periphery of the lifting assembly 1 to receive tobacco leaves that have fallen during cleaning. Specifically, the dust collection box 4 is circular, and its diameter is larger than the width of the box body, which can receive a wide range of tobacco leaves blown off by the jet assembly 2, making it convenient for workers to handle them centrally.

[0037] In optional embodiments, such as Figure 3 As shown, the chip collection box 4 includes two opposing box bodies connected to each other. Specifically, the box body has a semi-circular structure, consisting of a base plate 41 and a side plate 42. The side plate 42 is arranged along the arc-shaped edge of the base plate 41 and is perpendicular to the base plate 41. Both the side plate 42 and the base plate 41 of one box body are provided with a latching protrusion 43, and the side plate 42 and the base plate 41 of the other box body are provided with corresponding fasteners 44. The fasteners 44 have latching grooves. The opposing edges of the two box bodies have clearance recesses, which correspond to the end of the telescopic rod 13 of the lifting assembly 1 near the lifting cylinder 12. In use, the two box bodies are placed... At the corresponding position of the telescopic rod 13, and through the engagement of the slot and the protrusion 43, a chip collection box 4 is formed. The base plate 41 contacts the lifting cylinder 12, and the lifting cylinder 12 provides support to the chip collection box 4, so as to achieve stable installation of the chip collection box 4. After the chip collection box 4 collects and cleans the fallen tobacco leaves, the workers can quickly remove the chip collection box 4 from the lifting assembly 1 and pour the tobacco leaves in the chip collection box 4 into the main collection point for centralized processing. Furthermore, in order to reduce the weight of the chip collection box 4, the chip collection box 4 can be made of cardboard.

[0038] In use, the jet assembly 2 is installed on the lifting assembly 1. A flipping mechanism, such as a robotic arm, grips the perimeter of the box, flipping it so that the opening faces the jet assembly 2. The operator activates the lifting assembly 1 via a controller. The lifting cylinder 12 drives the telescopic rod 13 to extend, sending the jet assembly 2 from the opening into the box. When the proximity switch 3 detects that the distance between the lifting assembly 1 and the inner bottom surface of the box has reached a set position, the telescopic rod 13 stops extending. At this time, the first spray bar 211 approaches the inner bottom surface of the box, and the second air outlet 214 of the second spray bar corresponds to the inner corner of the box. The power source of the air pump 22 is activated, and compressed air enters the jet assembly 2 through the air supply pipe 23, spraying out through the first and second air outlets 213 and 214. Simultaneously, the telescopic rod 13 retracts, moving the jet assembly 2 along the height of the box to clean the inner surface, removing residual tobacco leaves and eliminating residual odors.

[0039] In summary, this automatic cleaning device uses four jet nozzles 21 positioned opposite the inner corner of the housing to target the inner corner, improving cleaning quality. Furthermore, the positioning of the four jet nozzles, in conjunction with the lifting assembly 1, creates a large airflow within the housing, effectively cleaning the inner surface of the housing, removing foreign objects and odors, and thus improving cleaning efficiency and quality.
