Abstract
The utility model relates to a sample preparing and perforating device used for measuring tobacco leaf thickness and leaf surface density, in particular to a perforating device of sample preparation used for measuring physical indexes of the tobacco leaf thickness and the leaf surface density, and belongs to the technical field of physical index measurement of tobacco leaves. The sample preparing and perforating device comprises a seat body (5), an upper cutter (3), a lower cutter (6), a pressing cover (1) and a spring (4), wherein the seat body (5) is provided with a space used for placing the upper cutter (3), the lower cutter (6) and the tobacco leaves, the upper cutter (3) and the lower cutter (6) are arranged on the seat body (5), the pressing cover (1) is fixed with the upper cutter (3) through fixing screws (2), and the spring (4) is wound on the upper cutter (3). The sample preparing and perforating device uses commercially available products or materials to prepare according to a conventional method, and has the advantages that the sample preparing process is rapid, simple and convenient and easy to operate, and the device is convenient to carry, free from consideration of factors of fields and external environment conditions, labor-saving, time-saving, and capable of accurately preparing samples which can measure the physical indexes of the tobacco leaf thickness and the leaf surface density.
Description
Technical field:
The utility model relates to a kind of sample preparation perforating device for measuring tobacco leaf thickness and surface density, is specially the perforating device of the sample preparation of measuring tobacco leaf thickness and surface density physical index, belongs to tobacco leaf physical index field of measuring technique.
Background technology:
The thickness of tobacco leaf refers to the thickness of tobacco leaf, and the vane thickness of tobacco leaf is the important physical proterties of tobacco leaf, reflected to a certain extent tobacco leaf development condition, maturity, beat leaf quality and quality of tobacco.Sound tobacco wants thickness moderate, namely can not be too thick, can not be too thin, and blade is excessively thin, and the tobacco leaf internal substance is not abundant, and output and quality are all lower; Blade is blocked up, and tobacco tissue is coarse, and the nitrogen-containing compounds such as nicotine are too high, and the jealous change of fragrance is bad.Simultaneously, the density of tobacco leaf and the quality of tobacco leaf be close relation also, tobacco leaf palisade cell density has reflected the tight and porousness of blade texture, mesophyll tissue's voidage (intercellular space) is the concentrated expression of cell density of mesophyll and cell shape etc., it is directly determining the density degree of tobacco tissue, its size directly affects the storage capacity of tobacco leaf internal substance and the accumulation of dry, the chemical quality harmony of generation and the fragrant jealous availability that greatly affects elasticity, fillibility and the Cigarette processing of tobacco leaf.So vane thickness, leaves density all are the important physical proterties of tobacco leaf, it is the important indicator of weighing the tobacco leaf physical characteristics.At present, although used sampler has the characteristics of mechanization, robotization, saving muscle power, but be only suitable for the batch samples preparation, under lab, few in sample size, the blade individual difference is larger, in the situation of blade face with breakage, be difficult to produce desirable sample with this sampler, add the restriction that is subjected to power supply, volume is heavy huge, and sampling just can't realize in the field.How convenient, prepare the sample of the new fresh tobacco leaf of flue-cured tobacco and field accurately, in order to finish the detection of thickness, two physical indexs of density, become those skilled in the art's problems of concern.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of quick, accurate, easy easy operating is provided, can be used in the sample preparation perforating device of measuring tobacco leaf thickness and surface density.
The device of the sample preparation punching for measuring tobacco leaf thickness and surface density of the present utility model, by have on it for put upper cutter (3) and lower cutter (6), and the pedestal (5) in the space of tobacco leaf, place upper cutter (3) on the pedestal (5) and lower cutter (6), the gland (1) of fixing by gib screw (2) and upper cutter (3), the spring (4) that is wrapped on the upper cutter (3) form.
The utility model adopts commercially available prod or material to prepare according to a conventional method.
The utility model has the advantage of: sample making course is quick, easy and easy to operate, easy to carry, need not consider place, external environment condition factor, saving of work and time can accurately be prepared simultaneously the sample of a plurality of measurement tobacco leaf thickness and leaves density index value.
Description of drawings:
Fig. 1 is the structural representation that master of the present utility model looks cut-open view.
Fig. 2 is the structural representation of looking up of the present utility model.
Embodiment:
The device of the sample preparation punching for measuring tobacco leaf thickness and surface density of the present utility model, by having on it for putting upper cutter 3 and lower cutter 6, and the pedestal 5 in the space of tobacco leaf, place upper cutter 3 and lower cutter 6 on the pedestal 5, by the gland 1 that gib screw 2 and upper cutter 3 are fixed, the spring 4 that is wrapped on the upper cutter 3 forms.
The utility model adopts commercially available prod or material to prepare according to a conventional method.Pedestal 5 adopts plastic material, to alleviate the weight of whole device, length preferably has 20cm long, meet half of tobacco leaf width, spring 4 should be selected enough toughness, plasticity, the material of high-yield strength, the anti abrasive light section material of gland 1, upper cutter 3 and lower cutter 6 usefulness, the diameter of upper cutter 3 is 2cm, and upper cutter 3 is vertical point-blank with lower cutter 6 phase inscribes.
During use: the intermediate space of open tobacco leaf being put into upper cutter 3 and lower cutter 6, produce as required the position adjustment of sample, press upper cutter 3, upper cutter 3 is with spring 4 stressed the moving downward of twining thereon under the effect of external force, the upper cutter 3 that moves downward is tangent with lower cutter 6, obtains required preparation sample.The present invention also can produce by the multi-disc tobacco leaf simultaneously.
Practical application shows: the utility model meets design requirement fully.
