Method and system for detecting blockage rate of negative pressure holes of drum

Abstract

The invention discloses a method and a system for detecting the drum wheel negative voltage hole blocking rate, and relates to the tobacco automatic control technology field, wherein the method for detecting the drum wheel negative-pressure hole blocking rate comprises: determining a detecting voltage value outputted by an opposite-type photoelectric detector when negative-pressure holes rotated with a drum wheel are operated to the opposite-type photoelectric detector; acquiring a reference voltage value outputted by the opposite-type photoelectric detector when the negative-pressure holes are operated to the opposite-type photoelectric detector under the condition of not blocking; and determining the blocking rate of the negative-pressure holes based on the voltage value and the reference voltage value that are detected. According to the invention, the blocking rate of the negative voltage hole is detected effectively, thereby providing accurate reference basis for the maintenance to the drum wheel by an operator; and at the same time, the occurrence rate of stopping accidents due to the blocking of the negative-pressure holes is reduced, thereby improving the production efficiency and the production quality of cigarette.

Description

technical field [0001] The invention relates to the technical field of tobacco automatic control, in particular to a detection system for the clogging rate of the negative pressure hole of a drum. Background technique [0002] figure 1 It is a schematic diagram of the movement of cigarettes on the drum. like figure 1 As shown, the wrapping machine of the crimping machine absorbs the cigarette 1 on the groove 3 of the outer drum 2 of the drum through negative pressure, and the cigarette 1 runs together with the drum, and completes the wrapping process of the cigarette during operation. [0003] figure 2 is the schematic diagram of the outer drum of the drum; image 3 is the schematic diagram of the cross-sectional structure of the drum; Figure 4 It is a schematic diagram of the cross-sectional structure of the drum with cigarettes. like Figure 2 to Figure 4 As shown, the drum wheel is made up of an outer drum 2 and an inner drum 5, the inner drum 5 is fixed, the inn...

Problems solved by technology

[0004] The inventors of the present invention found that with the operation of the machine, the smoke dust will gradually accumulate on the negative pressure hole 4, that is, the negative pressure hole 4 will be blocked, and the larger the blocked area, the more the negative pressure hole 4 will absorb the cigarette 1 The smaller the negative pressure, the more unstable the cigarette 1, the instability of the cigarette 1 will affect the production quality of the cigarette, increase the amount of waste products, and reduce the operating efficiency of the machine
