Abstract
The invention relates to a sample preparation punching device for measuring thickness and surface density of a tobacco leaf, in particular to a punching device for sample preparation for measuring physical indexes such as blade thickness and the surface density of the tobacco leaf, belonging to the technical field of tobacco leaf physical index measurement. The device is composed of a seat body (5), an upper cutter (3), a lower cutter (6), a gland (1) and a spring (4), wherein the seat body (5) is provided with a space for holding the upper cutter (3) and the lower cutter (6), the upper cutter (3) and the lower cutter (6) are arranged on the seat body (5), the gland (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 preparation punching device is manufactured by using commercially available products or materials according to a conventional method, and has the advantages of rapid sample preparation process, simpleness, convenience, easiness for operation, portability, freeness from considering field and external environment condition factors, labor/time-saving performance, and capability of accurately preparing a sample for the measurement of the physical indexes such as the blade thickness and the surface density of the tobacco leaf.
Description
Technical field:
The present invention relates to a kind of sample preparation perforating device that is used to measure tobacco leaf thickness and surface density, be specially the perforating device of the specimen preparation of measuring tobacco leaf thickness and surface density physical index, belong to tobacco leaf physical index field of measuring technique.
Background technology:
The thickness of tobacco leaf is meant 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, promptly can not be too thick, can not be too thin, and blade is thin excessively, 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 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 also have substantial connection; 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 mesophyll cell density and cell shape etc.; It is directly determining the density degree of tobacco tissue, and its size directly influences 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, blade density all are the important physical proterties of tobacco leaf, be the important indicator of weighing the tobacco leaf physical characteristics.At present, though used ST has the characteristics of mechanization, robotization, saving muscle power, only be fit to the batch samples preparation; Under lab, few in sample size, the blade individual difference is bigger; The blade face has under the damaged situation, is difficult to produce desirable sample with this ST, adds the restriction that receives 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 so that accomplish the detection of thickness, two physical indexs of density, become the problem that those skilled in the art pay close attention to.
Summary of the invention:
The objective of the invention 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 that is used to measure the sample preparation punching of tobacco leaf thickness and surface density of the present invention, by have on it be used to put 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), the gland of fixing through gib screw (2) and upper cutter (3) (1), the spring (4) that is wrapped on the upper cutter (3) form.
The present invention adopts commercially available prod or material to prepare by conventional method.
The invention has the advantages that: sample making course is quick, easy and easy to operate, and is easy to carry, need not consider place, external environment condition factor, and saving of work and time can accurately be prepared simultaneously the sample of a plurality of measurement tobacco leaf thickness and blade density index numerical value.
Description of drawings:
Fig. 1 looks the structural representation of cut-open view for master of the present invention.
Fig. 2 is the structural representation of looking up of the present invention.
Embodiment:
The device that is used to measure the sample preparation punching of tobacco leaf thickness and surface density of the present invention; Be used to put upper cutter 3 and lower cutter 6, and the pedestal 5 in the space of tobacco leaf by having on it; Place upper cutter 3 and lower cutter 6 on the pedestal 5; Through the gland 1 that gib screw 2 and upper cutter 3 are fixed, the spring 4 that is wrapped on the upper cutter 3 is formed.
The present invention adopts commercially available prod or material to prepare by conventional method.Pedestal 5 adopts plastic material, and to alleviate the weight of whole device, length preferably has 20cm long; Meet the half the 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 the position adjustment of sample as required; Press upper cutter 3; Upper cutter 3 is with spring 4 stressed the moving downward of twining above that under the effect of external force, and 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 present invention meets design requirement fully.
