Description
Technical field
The present invention relates to tobacco purchase classification field, more specifically, relate to a kind of tobacco leaf length continuous detection apparatus.
Background technology
When tobacco purchase stands in purchase tobacco, because land for growing field crops tobacco leaves property is different, after modulation, quality is not identical yet, if quality mixes, use value must reduce, and causes the wasting of resources, and economic benefit reduces.Former cigarette is through repeatedly processing, and scientific formula just can be produced and meet that consumer requires, that style is different cigarette, and scientific formula completes on the basis of tobacco leaf grading, if high-grade Virginian-type cigarette is based on middle leaf.Tobacco leaf grading is conducive to transferring tobacco grower and produces the enthusiasm of sound tobacco, increases the income of tobacco grower, with time stage and price also for tobacco grower specifies the direction of leaf tobacco production.Reasonable classification is conducive to carrying out and reasonably develops the exploitation inferior quality tobacco leaf of tobacco leaf secondary product and tobacco leaf secondary product.Therefore, tobacco leaf grading during tobacco purchase has great importance.
GB2635-1992 gives the standard of cured tobacco leaf classification, and be divided into 42 grades, the parameter that tobacco leaf grading relates to is more, comprises all many-sides such as position, color, oil content, colourity, width, length, thickness, residual wound and breakage.Wherein tobacco leaf length refers to that tobacco leaf is measured by the straight line of base portion to blade tip, measures primarily of the practical length of pommel along master pulse direction, with centimetre for linear module.Length is the important parameter of tobacco leaf grading, can reflect the quality of the quality of tobacco leaf.
Current tobacco leaf measurement of length has generally been come by mechanical implements such as slide calliper rule.Comparatively large to manually-operated dependence during kind of calliper, and the limited precision of slide calliper rule, there is comparatively big error when therefore the method measures tobacco leaf thickness, and measuring accuracy is low, speed is slow, efficiency is low, badly influences the progress of tobacco purchase.
Summary of the invention
The present invention overcomes that error described in above-mentioned prior art is large, precision is low, speed is slow, inefficient defect, provides the tobacco leaf length continuous detection apparatus that a kind of error is little, precision is high, speed is fast, efficiency is high.
