Deviation correction sensor and tobacco shred conveying device

Abstract

The invention discloses a deviation correction sensor and a cigarette making machine. The deviation correction sensor is arranged on a wall plate arranged on one side of a conveying belt or arranged on wall plates on the two sides of the conveying belt correspondingly, specifically, the deviation correction sensor comprises a fixing base used for being connected to a tobacco shred conveying device,a swing rod used for being rotationally connected to the fixing base, and an electromagnetic proximity switch used for detecting the position of the swing rod, wherein the electromagnetic proximity switch and the swing rod are correspondingly arranged, and the controller is electrically connected to the electromagnetic proximity switch and the tobacco shred conveying device. Compared with the prior art, the deviation correction sensor is small in pushing force, can detect the deviation amount of the conveying belt more accurately, induces through electromagnetism, is not sensitive to dust, can still detect the conveying belt under the condition that the deviation correction sensor is blocked by dust, therefore, long-term stable work of the deviation correction sensor is effectively guaranteed, and smooth operation of the tobacco shred conveying device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cigarette machinery, in particular to a deviation correction sensor and shredded tobacco conveying device. Background technique [0002] Pneumatic shredded tobacco conveying is a wire feeding method in the cigarette process. The material is conveyed to the designated place through the flow of gas, or the technology of conveying the material through the pipeline with the help of positive or negative airflow. There will be a large amount of dust during the process of the device carrying out shredded tobacco delivery. [0003] Pneumatic shredded tobacco conveying devices generally use wide belts for shredded tobacco conveying. During the shredded tobacco conveying process, the conveyer belt will shift to both sides and rub against the wall panels on both sides, resulting in damage to the conveyer belt. The current device for detecting whether the conveyor belt is offset is generally to install a photoelectr...

Problems solved by technology

[0003] The pneumatic shredded tobacco conveying device generally uses a wide belt for shredded tobacco conveying. During the shredded tobacco conveying process, the conveyer belt will shift to both sides and rub against the wall panels on both sides, resulting in damage to the conveyer belt.

The current device for detecting whether the conveyor belt is offset is generally to install a photoelectric switch or an optical fiber near the conveyor belt. Since the photoelectric switch or optical fiber is easily affected by the intensity of light, not only the detection result is inaccurate, but also after a long time of use, Dust will cover the photoelectric switch or optical fiber, resulting in the phenomenon that the photoelectric switch or optical fiber cannot be detected
