Abstract
The invention relates to a method for determining the structure of cut tobacco and a testing vibration sieve for that, which is characterized in that, certain amount of cut tobacco sample to be tested is placed evenly on a conveying belt, and a sieve mesh at the top layer of a testing sieve comprising a plurality layers of sieves that are placed layer by layer according to the sieve mesh sizes is supplied with cut tobacco by the conveying belt at set speed; the cut tobacco in size bigger than the mesh at the top layer will go into a first cut-tobacco collecting and weighing container, the rest will go to the second layer; the cut tobacco in size bigger than the mesh at the second layer will go into a second cut-tobacco collecting and weighing container, the rest will go to the third layer, and so on; in this way, the cut tobacco of different structural sizes can be separated; finally, by weighing, the masses of different cut tobaccos can be obtained; and the proportions of different cut tobaccos can be obtained through dividing the masses of different cut tobaccos collected in each cut-tobacco collecting and weighing container by the total mass of the sample.
Description
Technical field
The present invention relates to the tobacco process technology, particularly a kind of method of the mensuration tobacco structure that is used to measure different size pipe tobacco distribution proportion and detection thereof the sieve that shakes.
Technical background
In the production of cigarettes process of tobacco business, and in the quality testing to cigarette product, pipe tobacco size detection to pipe tobacco all is very important link, it clearly reflected cigarette throwing, pipe tobacco mix join, the quality control situation of each operation such as cigarette, the tobacco structure of finished cigarettes also directly affects the physics and the aesthetic quality of cigarette.
In recent years, along with deepening continuously of cigarette process research, the engineering research that especially lowers consumption makes substantial progress, and has promoted greatly on the whole in China's cigarette process at the physical quality of goods and the external quality of product.Show that through the investigation test result to domestic how tame key enterprise the whole cut rate of pipe tobacco has all reached more than 80.0%, filament broken rate is controlled at below 3.0%.Because present stage does not also have the more complete feasible method of a cover for the concrete distribution situation of tobacco structure, therefore cigarette enterprise is to the present mensuration that also only is confined to whole cut rate and filament broken rate of the detection of tobacco structure, cause in fiber tow production, it is better to tend to occur the tobacco structure index, under the certain prerequisite of control cigarette short rate, individual cigarette weight is bigger sometimes; Under the certain prerequisite of control individual cigarette weight, the nominal rate that cigarette props up is higher sometimes.Therefore the tobacco structure of only describing with whole cut rate and filament broken rate is very general and incomplete.
Summary of the invention
But purpose of the present invention provides a kind of method of fast measuring tobacco structure and detection thereof the sieve that shakes just at existing problem in the above-mentioned prior art.
Purpose of the present invention can realize by following technique measures:
The method that is used to measure tobacco structure of the present invention comprises the steps: the even cloth of detected sample pipe tobacco of certain mass is placed on material conveyer belt, and give the top layer sieve nest feed that shakes and sieve by the detection formed of the sieve nest of storied placement from top to bottom of its screen cloth mesh size size by several layers by the speed of setting by material conveyer belt, physical dimension enters first pipe tobacco greater than the pipe tobacco of top layer mesh and collects the container of weighing, all the other enter second layer sieve nest, physical dimension enters second pipe tobacco greater than the pipe tobacco of second layer mesh and collects the container of weighing, all the other enter the 3rd layer of sieve nest, so can isolate the pipe tobacco of some kinds of different structure sizes after the circulation; Afterwards, obtain each pipe tobacco by the weighing mode and collect in the container of weighing the quality of pipe tobacco separately, each quality of collecting pipe tobacco in the container of weighing is compared with the gross mass of institute sample thief respectively with gained again, can obtain the pipe tobacco ratio of some kinds of different structure sizes.
The detection that is used for said method among the present invention shake sieve comprise frame, be positioned at upper rack material conveyer belt, be arranged on the several layers sieve nest of material conveyer belt below, described sieve nest is pressed its screen cloth mesh size size storied placement from top to bottom, the two ends of every layer of sieve nest are suspended in the frame by the swing hanging piece respectively, and the eccentric driving device that is used to drive the sieve nest motion is positioned at a side of sieve nest and links to each other with sieve nest by drive link; Every layer of sieve nest is provided with one and is used to collect and is positioned at the size of screen cloth below less than this layer screen cloth mesh pipe tobacco undersize material escape hole after the size that is retained in after the screening on the screen cloth is used to collect screening greater than the screen overflow material escape hole of this layer screen cloth mesh pipe tobacco and one, being positioned at two discharging openings on the orlop sieve nest collects the container of weighing with pipe tobacco respectively and is connected, screen overflow material escape hole on all the other each layer sieve nests is collected the container of weighing with a pipe tobacco respectively and is connected, and the undersize material escape hole is connected with the inlet of following one deck sieve nest.
Sieve nest described in the present invention can be made up of five layers of sieve nest that are provided with from top to bottom, and five layers of sieve nest constitute a rigid body member by web member; Say that more specifically described five layers of sieve nest constitute a rigid body member by the web member that is arranged on the one end, this architectural feature can make the amplitude of all sieve nests and frequency be consistent, and vibration frequency can be adjusted on demand; The travelling speed of conveying belt can be adjusted on demand.
For adapting to the needs of different examination criterias, the screen cloth of sieve nest described in the present invention comprises the interchangeable screen cloth that nine kinds of mesh sizes do not wait, and wherein four kinds of screen clothes are standby, can exchange arbitrarily with other five kinds of screen clothes.
Described pipe tobacco is collected the container of weighing for waiting quality structure (weight is identical) and rounding demarcation.
The present invention provides a kind of comparatively complete, feasible method for the concrete distribution situation of fast measuring tobacco structure, the employing of the method can be by the method for improving tobacco structure and improves cigarette quality that cigarette props up, reduces the cigarette individual cigarette weight reliable technique parameter is provided, and can promote the physical quality of China's cigarette products and the external quality of product on the whole.
Detection of the present invention is shaken to sieve and can be prevented effectively that pipe tobacco mistakes and omissions or quilt from being dammed on the screen layer of larger aperture size, makes the pipe tobacco screening result can reflect the dimensional structure of pipe tobacco more accurately, thereby realizes the control to tobacco quality more accurately.
