[0030] A water collection tank 240 (see dark blue line) and a water pump 243 are provided below the cleaning conveyor chain 210 . The inlet of the water pump 243 is in the water collection tank 240 , and the outlet of the water pump 243 is connected to the clean water pipeline 230 .

[0031] like Figure 3 The cleaning frame 220 is provided with a cleaning tool, which includes a sliding frame 260. The sliding frame 260 can slide vertically on the cleaning frame 220, and a cleaning motor 261 is fixed on it. The output shaft of the cleaning motor 261 is fixed to the upper end of the rotating shaft 262. The rotating shaft 262 is arranged up and down, and a cleaning roller 263 is fixed at its lower end. Two bearings 264 are provided between the rotating shaft 262 and the sliding frame 260.

[0032] The sliding frame 260 is connected to a power mechanism, which can drive the sliding frame 260 to slide vertically. Specifically, the power mechanism includes a lifting motor 282, a fixed block 280 and an adjusting chain 270. The first end 271 of the adjusting chain 270 is fixed on the fixed block 280. The first end 271 is connected to the lower part 272 of the chain. The lower part 272 of the chain gradually bends downward from the first end 271, passes through the lower guide sprocket 265 for guidance, bends upward and wraps around the driving sprocket 281, and the lower part 272 of the chain passes around the driving sprocket 281 to become the upper part 273 of the chain. The upper part 273 of the chain gradually bends upward, passes through the upper guide sprocket 266 for guidance, bends downward and wraps around, and finally forms the second end 274 of the adjusting chain 270. The second end 274 is fixed on the fixed block 280.

[0033] The lower guide sprocket 265 and the upper guide sprocket 266 are rotatably connected to the sliding frame 260 , the driving sprocket 281 is rotatably connected to the cleaning frame 220 , and the lifting motor 282 is fixed to the cleaning frame 220 , and its output shaft fixes the driving sprocket 281 .

[0034] In order to detect the position of the cigarette frame, the softening station 100 , the cleaning station 200 , and the drying station 200 are all provided with an entry position sensor 111 and an exit position sensor 112 .

[0035] When the cleaning roller 263 rotates, its outer contour traces a circular ring, while the cigarette frame is square. In order to avoid the problem of not being able to reach the corners, further improvements are made as follows:

[0036] like Figure 4 The outer contour of the cleaning roller 263 is fixed with multiple cleaning foam brushes (a type used in car washing machines) 265. The cleaning foam brushes 265 have a certain flexibility and can reach the corners of the cigarette frame.

[0037] In order to prevent debris such as broken cigarettes from entering the water collection pool, a filter 241 is provided in the water collection pool 240 , and the filter 241 fixes the handle 242 .

[0038] Its working principle is:

[0039] like Figure 1-4 , a cleaning method comprising the following steps.

[0040] S1. Preparation: Connect the return pipe 130 to the steam pipe, inject clean water into the water collection tank 240, and connect the air pipe 330 to the high-pressure gas source.

[0041] S2, Softening: Connected to the upstream equipment, the cigarette frame gradually enters the softening station 100 on the softening conveyor chain 110. When the first sensor of the softening station 100 detects a cigarette frame, the valve of the softening duct 130 opens, and water vapor is ejected from the softening nozzle 131, which softens the firmly bonded cigarette pieces and weakens the adhesion between them and the cigarette frame. When the second sensor detects a cigarette frame, the softening conveyor chain 110 stops.

[0042] S3. Cleaning: The cleaning tool rises to a high position and docks with the upstream equipment. The cigarette rack gradually enters the cleaning station 200 via the cleaning conveyor chain 210. When the first sensor of the cleaning station 200 detects the cigarette rack, the water pump 243 is turned on and clean water is sprayed from the cleaning nozzle 231. The clean water and debris such as broken cigarette pieces flow downward and enter the water collection tank 240. The broken cigarette pieces and other debris are separated by the filter 241. The clean water enters the water collection tank and can be circulated. When the cleaning tool rises to the highest point, the water pump 243 stops.

[0043] When the second sensor of the cleaning station 200 detects the cigarette frame, the cigarette frame is in place and the cleaning conveyor chain 210 stops; the cleaning tool gradually descends, and at the same time, the cleaning motor 261 drives the rotating shaft 262, the cleaning roller 263, and the cleaning foam brush 265 to rotate, and the cleaning foam brush 265 can brush away debris such as broken cigarette pieces;

[0044] Among them, the lifting of the cleaning tool is specifically as follows: the lifting motor 282 drives the driving sprocket 281 to rotate counterclockwise, the lower part of the chain 272 becomes shorter, and the upper part of the chain 273 becomes longer, the lower guide sprocket 265 and the upper guide sprocket 266 rise, driving the sliding frame 260 to rise; the lowering of the cleaning tool is similar and will not be described.

[0045] After the cleaning action is completed, the cleaning tool rises to a high position and waits for the smoke frame to be moved out.

[0046] S4. Drying: After connecting with the upstream equipment, the cigarette frame gradually enters the drying station 300 on the drying conveyor chain 310. When the first sensor of the drying station 300 detects the cigarette frame, the valve of the air duct 330 opens, and air is ejected from the air nozzle 331 to dry the moisture on the cigarette frame. When the second sensor of the drying station 300 detects the cigarette frame, the air duct stops supplying air and the operation is completed.

[0047] After the smoke frame is cleaned, the drying conveyor chain 310 continues to move forward and enters the downstream to connect with the downstream equipment.

[0048] Features of this application:

[0049] S1. The entire device system operates continuously online in real time and is automatically cleaned without manual labor.

[0050] S2. First, use high-temperature steam to heat the upper and both sides of the smoke frame in the first process.

[0051] S3. The cleaning foam brush adopts a long ribbon of foam brush. When it rotates, the cleaning brush uses centrifugal force to clean and beat the cigarette frame to remove broken cigarette pieces and dust.

[0052] S4, the cleaning rack moves up and down and rotates for cleaning.

[0053] S5. The water collection tank can collect clean water, filter and precipitate it, and then reuse it through a small water pump.

[0054] S6. The filter is isolated by a mesh plate, and the filter debris can be removed by the handle after a period of time to clean it.

[0055] S7. The third process is to automatically dry the water stains on the surface of the smoke frame by using dry compressed air.

[0056] S8. Both sides of the system are sealed into a closed space by plastic plates to prevent high-temperature steam and water from flowing freely.

[0057] S9. Compared with the prior art, the technical effect of the present invention is that the present invention is provided with three conveyor chains, which realizes automatic transfer; through hot air softening, cleaning tools sweeping, and cold air drying, broken cigarette pieces and other debris are removed, realizing automatic cleaning.

[0058] S10, the softening station 100, the cleaning station 200, and the drying station 300 are all equipped with two position sensors, which can realize automatic position detection.

[0059] For other contents, please refer to the prior art.

[0060] The above description is only the preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
