Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco equipment, and particularly relates to a new type of metering tube based on grating detection. Background Art

[0002] In the tobacco industry, metering tubes can be used to accurately measure the amount of tobacco, spices and other materials, ensure the accuracy and consistency of product formulas, and thus ensure the stability of product quality; they can also help achieve quantitative feeding in the automated production process, and improve production efficiency and accuracy. The traditional metering tube uses three to four photoelectric tubes to detect the material in the metering tube, thereby obtaining the "bottom material level", "middle material level", "high material level" and "blocking material level" signals. This detection method cannot provide accurate height signals of the material in the metering tube, and its detection method is too simple to achieve accurate control of the height of the material in the metering tube; it cannot provide real-time height changes in the metering tube for the linear adjustment of the running speed of the upstream feeding equipment; it cannot achieve blockage and overhead alarms through the height detection of the material in the metering tube. When blockage or overhead occurs, the traditional metering tube body cannot be adjusted accordingly due to its fixed structure, that is, the flow rate or volume adjustment to alleviate the sudden situation during material transportation, resulting in production efficiency being affected.
