Given the shortcomings of the traditional tobacco feeder nozzle spatial position and angle adjustment process, such as the need for multiple people to cooperate, long time-consuming, and lack of quantitative adjustment devices and methods, this paper puts forward an improved design scheme for the nozzle spatial position and angle adjustment device. Combined with the new adjustment method, through the installation, debugging, and testing of the improved device, it can realize the visual, quantitative, and standardized adjustment of the nozzle’s spatial position and angle outside the drum. The field test results show that the application of the adjustment device and method greatly shortens the adjustment time of nozzle spatial position and angle, and improves the adjustment efficiency by about 82.79%. The visual and quantitative nozzle spot inspection work is realized, which is conducive to the timely discovery and rectification of its abnormal spatial position and angle, improves the homogenization level of the liquid spraying process, and reduces the weight of tobacco leaves adhered to the surface of the drum, which is conducive to improving the internal quality of tobacco leaves and reducing the waste of tobacco raw materials.
