Description

Technical Field

[0001] The utility model relates to the technical field of cigarette making machines, and more specifically, to a tobacco bundle height detection device for cigarette making machines. Background Art

[0002] In cigarette production, precise control of tobacco quantity is a key factor in ensuring consistent cigarette quality. Tobacco not only affects the flavor and combustion properties of cigarettes, but also directly impacts their appearance, weight, and overall smoking experience. To effectively monitor tobacco quantity, modern cigarette production lines often employ line laser sensors to measure the height of the tobacco bundle. Line laser sensors transmit a laser beam to the surface of an object and receive the reflected light. Line laser sensors calculate the object's position or height based on the deflection angle or time difference of the reflected light. Installing these sensors before and after the leveling plate allows for real-time monitoring of tobacco bundle height changes, indirectly reflecting incoming and returned tobacco quantities.

[0003] Traditional line laser sensors are difficult to deploy effectively in confined spaces due to their large size and specialized installation requirements. This not only increases the installation difficulty but can also impact the overall layout and operational efficiency of the equipment. When installing sensors in confined spaces, spatial constraints often prevent optimal sensor placement and angle, which can negatively impact detection accuracy.

[0004] Prior art also discloses installing laser sensors on mounting plates in front and behind the cigarette leveling plate. The height difference of the tobacco bundle measured by the front and rear sensors is used to determine whether the tobacco feed is blocked. The sensors used in this device have low measurement accuracy and are only used to detect tobacco blockage. Furthermore, the sensors are single-point sensors, which can lead to measurement errors compared to actual values. They also lack position adjustment and cleaning capabilities. Utility Model Content
