Description

A kind of test method of filament cutter chopping effect
Technical field
Present invention relates particularly to a kind of test method of filament cutter chopping effect.
Background technology
Filament cutter is the key equipment that tobacco industry uses, and is that tobacco leaf or offal are processed into setting for pipe tobacco shape by scrap prodn. line It is standby.Its operation principle is the tobacco leaf (offal) of certain flow to be pressed into tobacco leaf (offal) layer of certain thickness, width, forward at the uniform velocity Conveying, then cuts tobacco leaf layer by the cutter of certain speed, tobacco leaf is cut into the Filamentous pipe tobacco of one fixed width.
During tobacco leaf chopping, there is some factor to influence filament cutter chopping quality：1) tobacco leaf layer conveying speed and cutter fortune Dynamic cooperation, determines tobacco cut width, and speed mismate will cause to cut out pipe tobacco width inaccurate or unstable；2) blade sharper Degree, if blade is not sharp enough, the pipe tobacco width cut out is uneven, and notch is coarse, and increases the loss of chopping process tobacco leaf；3) Artificial behavial factor control cuts out tobacco quality.At present, width detection is carried out by the pipe tobacco sampling to cutting out, evaluates filament cutter Working status, evaluate the tobacco quality cut out.
The tobacco quality that the working status of sampling detection method evaluation filament cutter, evaluation are cut out, there is significant limitations：
1) during tobacco leaf (offal) being pressed into tobacco leaf (offal) layer of certain thickness, width due to filament cutter, due to cigarette Leaf (offal) shape, arrangement irregular, tobacco leaf postback raw folding, curling, and the pipe tobacco shape cut out is also irregular, same root cigarette Between silk diverse location, different pipe tobaccos, width has very big difference, it is difficult to accurate evaluation tobacco cut width precise control, although row Industry specification requires coherent detection amount and detection method, but is still difficult to thoroughly eliminate；2) testing result is not representative, One production batch pipe tobacco amount of throwing reaches several tons, and actually detected pipe tobacco only has several grams, therefore is not representative.Pass through reality Border detection data also demonstrate that sampling detection data fluctuations are big, and data are representative not enough；3) detection process is loaded down with trivial details, is examined from being sampled to Data are measured, it is necessary to which a skilled testing staff takes or so 1 hour, operating process is loaded down with trivial details；4) it is high to detect the frequency, according to row Industry process specification requirements, it is every 1 it is small when or so need detection 1 time.
The content of the invention
The object of the present invention is to provide a kind of pneumatic separating using unified standard to test standard specimen, evaluates wind sorting equipment Working status, and by the evaluation to equipment state, evaluates indirectly and accurately wind sorting equipment in the operating condition The test method of the filament cutter chopping effect of the efficiency of separation.
In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of test method of filament cutter chopping effect, comprises the following steps：
1) the standard testing body of filament cutter measure of merit is made, standard testing body is uniformly mixed by silica gel and iron powder, is made Shape is in strip, single test body contains 10% -80% magnetic material, and the silica gel of 20%-90%, rubber or latex Class material；
2) under filament cutter working status, standard testing body is put into tobacco leaf and passes through running filament cutter, uses strong magnetic Body all takes out the standard testing body section cut out；
3) cut into slices to the standard testing body taken out after cutting, average thickness is measured using vernier caliper, judge that pipe tobacco is actual and cut Silk width, judges filament cutter width control system accuracy, observes the standard testing body smooth cut degree after cutting, judges chopping machine knife Piece sharpness, by weight loss ratio before and after calculating standard testing body chopping of weighing, judges chopping process loss rate, specifically Calculation is：
1. the actual tobacco cut width of pipe tobacco=cut out standard testing body slice thickness average value；
2. pipe tobacco width criteria deviation=ξ1× standard testing body slice thickness standard deviation is cut out, wherein, ξ1It is to correct Number, computational methods are：
ξ1=pipe tobacco width criteria deviation/cuts out standard testing body thickness section standard deviation；
3. chopping process loss rate=ξ2Standard testing body total amount before × (cutting out standard testing body total amount)/cuts, wherein, ξ2 For correction factor, computational methods are：
ξ2The proportion of goods damageds for=actual test the proportion of goods damageds/tried by standard testing body examination.
Further, in step 1), for used standard testing system as rectangle, size is 15 × 20 × 100, Single test body contains the magnetic material of 40-50%, and the silica gel of 50%-60%, rubber or latex class material.
Root is not it was found that (event occurs for not more allowing blade replacement, emery wheel, or equipment in the case of filament cutter equipment state does not change Barrier etc.), filament cutter operating status is stable, and cigarette (stalk) quality state cut out is also stable, and therefore, sampling detection is cut out The method of tobacco quality state, can be replaced by evaluating filament cutter working status, moreover, by evaluating filament cutter working status More accurate, science, operation are succinct.Filament cutter working status is evaluated, and is using the silica gel containing magnetic material, rubber, latex class The test body of the shapes such as spherical, the bar-shaped, pie that material is fabricated to, by running filament cutter, then collects the survey cut out Body is tried, according to the thickness of the test body cut out, smooth cut degree, test body weight loss, is evaluated in filament cutter test process Tobacco cut width accuracy, blade sharper degree, chopping loss.
The beneficial effects of the invention are as follows：The evaluation of pipe tobacco width judges that result is more accurate, since testing standard shape is regular, Pipe tobacco width representativeness is greatly increased according to the standard body thickness cut out, more can accurate evaluation filament cutter pipe tobacco width control system shape State；The representative increase of testing result, by evaluating filament cutter working status, can more accurate evaluation equipment stablize during material chopping Quality state；Detection process is succinct, and data are detected, it is necessary to a skilled testing staff takes 10 minutes or so from being sampled to, Step is simpler；It is low to detect the frequency, according to filament cutter operation characteristic, during equipment stable operation (general 12 hours) It is interior, it is only necessary to test evaluation 1 time.
