Abstract
A sample perforating device suitable for measuring the density of the leaf surface of a tobacco leaf is characterized in that the device comprises a sample placing table and a ram type hole puncher arranged on the sample placing table and driven by a power device; a die hole is formed on the sample placing table and matched with the position of the hole puncher and the cross section of a punch head; a sample collection box is arranged below the die hole; the cross section of the punch head of the hole puncher has a cylindrical structure; and 2-3mm of punch edge at the lower end of the punch head is a hollow structure so as to abrade the lower end of the hole puncher to be more sharp at the premise that the inner diameter remains unchanged. The utility model has the characteristics of mechanization, automation, strength saving, quick and sample preparation, etc. In addition, the utility model dispenses with manual perforating operation, is suitable for mass sample preparation, is a key instrument used in the process of measuring the density of the leaf surface of the tobacco leaf, and is widely applied in the measurement of physical characteristics of tobacco leaves, and perforating sample preparation of fresh tobacco leaves or other plants.
Description
Technical field
The utility model belongs to quality of tobacco detection technique field, is specifically related to a kind of sample preparation perforating device of measuring tobacco surface density that is applicable to, this device can carry out sample preparation fast to cured tobacco leaf; Simultaneously this instrument can also be used to the fresh tobacco leaf sample preparation, carries out the mensuration of various physical signs (as photosynthetic, respiratory intensity etc.) and carries out tobacco leaf DNA or Protein Detection (detection transgene tobacco).
Background technology
Raw tobacco material is the basis of cigarette industry, the good and bad quality that directly influences cigarette product of quality of tobacco.The tobacco leaf physical characteristics is to estimate the important indicator of quality of tobacco, and tobacco surface density is a major parameter of tobacco leaf physical characteristics, is one of important references index of estimating the quality of tobacco height.The used tobacco leaf density of tobacco business mainly refers to the quality of tobacco of unit area, the g/m of unit at present
2Expression, tobacco leaf density are the important characteristic indexs of the loose compactness extent of its internal organizational structure, and with the filling capacity of tobacco leaf, flammability etc. all have substantial connection.Li Rongchun etc. discover that tobacco leaf density and potassium content are in close relations, the structure exquisiteness, fine and close higher (the Li Rongchun etc. of potassium content in tobacco leaf leaf, 2001), current research such as Wu Guohe find that tobacco leaf density, internal organizational structure and blade degree of ripeness are negative correlation (Wu Guohe etc., 2007), Huang Yong etc. also find from underdone to the proper mature (ripe) process the tobacco leaf fraction void be (Huang Yong etc., 2008) that continue to increase.Deng Xiaohua etc. analyze the just roasting sample of 757 flue-cured tobaccos, find that surface density and degree of ripeness, blade construction, identity, oil content all have certain correlativity, also obviously relevant with tobacco incense makings, flammability (Deng Xiaohua etc., 2008) simultaneously.Therefore the mensuration of tobacco surface density is one of important process of quality of tobacco evaluation.
Specimen preparation mainly is to utilize the evenly punching sample preparation on cured tobacco leaf of traditional card punch in the tobacco leaf density inspect method at present, measures then.Though that the method has is objective, can repeat, characteristics such as be not subjected to that human factor influences, sample preparation efficient is low, in the face of a large amount of sample detection, needs a large amount of manpowers, time, can not adapt to the requirement of present tobacco leaf mass detection.
Summary of the invention
The purpose of this utility model is just at existing problem in the above-mentioned prior art and custom-designed a kind of rational in infrastructure, operating aspect, the simple and practical sample preparation perforating device of measuring tobacco surface density that is applicable to, this perforating device can carry out evenly cured tobacco leaf, sample preparation fast, guarantee that sample is representative, realized the purpose of the mechanized operation that tobacco sample detects.
The purpose of this utility model realizes by following technical measures: be applicable to that originally the sample preparation perforating device of measuring tobacco surface density comprises sample storing platform and is arranged on the ram-type card punch of putting on the platform by the propulsion system driving, on the storing platform, offer the nib that is complementary with card punch position and drift cross section, below nib, be provided with the sample collection box.
In the utility model, the drift cross section is a cylindrical structural, and punching press edge, drift lower end 2-3mm is a hollow structure, is keeping under the constant prerequisite of internal diameter, and that the card punch lower end edge can be polished is sharper.Propulsion system are controlled by functional switch, and this functional switch is provided with energising, time-out, three positions of operation.
The utility model operating process is as follows: connect power supply, after opening switch, card punch punches according to 5 seconds each frequencies under power drive, the operator places sample divider under the nib in advance, and both hands are close to the nib place with suitable sample preparation position after taking mounted blade, sample will be laid and directly be dropped in the sample divider, change a position after the sample preparation in addition and continue sample preparation, after had got at 5 positions, other changed the sample preparation of a slice tobacco leaf.One group of sample sample preparation finishes, and by suspending the strong punching that stops, taking out sample divider, treats that another group sample is ready to, and continues punching.
This utility model has characteristics such as mechanization, robotization, saving muscle power, sample preparation is quick, removed the operation of artificial punching muscle power from, be fit to the batch samples preparation, be the critical equipment that tobacco surface density mensuration process is used, in tobacco leaf physical characteristics mensuration, fresh tobacco leaf or other plant punching sample preparation, have extensive use.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1. propulsion system, 2. functional switch, 3. attaching plug, 4. card punch, 5. sample is put platform, 6. nib, 7. support, 8. sample divider.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in the figure: be applicable to that originally the sample preparation perforating device of measuring tobacco surface density comprises sample storing platform 5 and is arranged on the ram-type card punch of putting on the platform 4 by propulsion system 1 driving, on the storing platform, offer the nib 6 that is complementary with card punch position and drift cross section, below nib, be provided with sample collection box 8, card punch 4 drift cross sections are cylindrical structural, punching press edge, drift lower end 2-3mm is a hollow structure, be convenient to keeping under the constant prerequisite of internal diameter sharper with the polishing of card punch lower end edge.
Propulsion system 1 are by functional switch 2 controls, and this functional switch is provided with energising, time-out, three positions of operation.
