Description

Technical Field

[0001] The utility model relates to the technical field of cigarette processing equipment, in particular to a cleaning device used for cigarette detection of a cigarette packaging machine. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Before cigarette packaging, cigarettes are sorted in the mold box to form 20 neatly arranged cigarettes in the top, middle and bottom layers. However, during the production process, there are empty, broken, skewed, missing cigarettes, etc., so a detection device is needed to detect these unqualified cigarettes and remove them. In the cigarette mold box conveying channel, there are multiple defect detections to detect whether the cigarettes in the mold box are qualified and remove unqualified cigarettes. However, during the production process, due to the fast running speed and vibration of the equipment, the tobacco and cigarette dust at the end of the cigarette will fall off. Often, after a period of production, a large amount of tobacco soil and cigarette dust will accumulate in the cigarette conveying channel. On the one hand, these tobacco soil and cigarette dust will adhere to the photoelectric detection surface, affecting the detection accuracy, and the qualified cigarettes will be removed or the unqualified cigarettes will not be removed, which will lead to increased cigarette consumption or the flow of unqualified cigarettes into the next process; on the other hand, excessive accumulation of tobacco soil and cigarette dust will cause abnormal error reporting of defect detection, resulting in equipment shutdown and affecting production efficiency. When a fault in detection causes shutdown or abnormal detection, operators are often required to manually clean and check whether unqualified cigarettes enter the next process, which affects production efficiency and increases machine consumption.

[0004] The Chinese patent with the patent number "CN212172636U" proposes an automatic cleaning device for the cigarette conveying part of the ZB45 / ZB25 packaging machine. The device uses high-pressure air to blow up the cigarette dust accumulated between the conveyor belt and the pulley, and uses the pneumatic conveying principle to generate a low-pressure area (vacuum) with the high-pressure air on the machine table to suck the cigarette dust out of the machine body cavity of the cigarette conveyor belt. The device has the following two shortcomings. On the one hand, the device position setting is relatively simple, and the device is set to spray the tobacco in the gap between the transmission gear of the conveyor pulley and the wall panel. In the actual production process, tobacco and tobacco dust will also accumulate in the cigarette conveying channel. At the same time, the device does not clean the cigarette detection device. On the other hand, in the actual production process, the tobacco and tobacco dust are easily caused to fall into the cigarette mold box through spraying, and enter the next process for packaging, affecting the product quality.

[0005] The Chinese patent with the patent number "CN208603248U" proposes a cigarette conveying toothed belt cleaning device for a cigarette packaging unit. It has a simple structure and has the following shortcomings: the cleaning effect is better when the equipment is stopped and there are no cigarettes in the cigarette mold box, but when the equipment is running and there are cigarettes in the cigarette mold box, positive pressure blowing can easily cause the cigarettes in the mold box to shift, which can easily cause the cigarettes to be squeezed and deformed during the transportation process, affecting the quality of the cigarettes.
