Abstract
The invention discloses a method for testing the tobacco cutting effect of a tobacco cutter. The method comprises the following steps: preparing a standard test object to be cut by the tobacco cutter, putting the standard test object in the tobacco cutter in the production process, taking out the cut standard test object by using a powerful magnet, and evaluating the cut tobacco width accuracy, the sharpness of a blade and the cut tobacco loss according to the cut standard test object in the process of testing. The method disclosed by the invention has the advantages that the cut tobacco width accuracy can be evaluated and judged accurately, the representativeness of the testing result on the actual tobacco cutting quality can be improved, the detection process and step are simple, and the detection frequency is low.
Description
Technical field
The present invention relates to the technical field that filament cutter chopping measure of merit is evaluated, be specifically related to a kind of method of testing of filament cutter chopping effect.
Background technology
The key equipment of filament cutter wind and smoke grass industrial application is that scrap prodn. line is processed into the equipment of pipe tobacco shape tobacco leaf or offal.Its principle of work is tobacco leaf (offal) layer tobacco leaf of certain flow (offal) being pressed into certain thickness, width, at the uniform velocity carry forward, then by the cutting knife of certain speed, tobacco leaf layer is cut, tobacco leaf is cut into the thread pipe tobacco of one fixed width.
In tobacco leaf chopping process, have some factor to affect filament cutter chopping quality: the 1) cooperation of tobacco leaf layer transporting velocity and cutting knife motion, determine tobacco cut width, it is inaccurate or unstable that speed mismate will cause cutting out pipe tobacco width; 2) blade sharper degree, if blade is sharp not, the pipe tobacco width cut out is uneven, and otch is coarse, and increases the loss of chopping process tobacco leaf; 3) for controlling by cutting out tobacco quality, at present, by carrying out width detection to the pipe tobacco sampling cut out, evaluating the duty of filament cutter, evaluating the tobacco quality cut out.
The tobacco quality that the duty of sampling detection method evaluation filament cutter, evaluation cut out, has very large limitation:
1) because filament cutter is pressed into tobacco leaf (offal) in tobacco leaf (offal) the layer process of certain thickness, width, due to tobacco leaf (offal) shape, arrangement irregular, tobacco leaf postbacks raw folding, curling, the pipe tobacco shape cut out is also irregular, between same pipe tobacco diverse location, different pipe tobacco, width has very big-difference, be difficult to the precise control of accurate evaluation tobacco cut width, although industry standard has done requirement to coherent detection amount and detection method, be still difficult to thorough elimination; 2) testing result representativeness is not strong, and throwing production batch pipe tobacco amount reaches several tons, and the actual pipe tobacco detected only has several grams, and therefore representativeness is not strong.Detect data by reality also to prove, it is large that sampling detects data fluctuations, and data are not representative; 3) testing process is loaded down with trivial details, detects data from being sampled to, and need skilled testing staff 1 hours consuming time, operating process is loaded down with trivial details; 4) detect the frequency high, according to industry process specification requirements, every 1 hours needs detection 1 time.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of pipe tobacco width evaluate result of determination more accurately, testing result increases actual chopping quality representativeness, testing process is succinct, step is more simple and detect the method for testing of the low filament cutter chopping effect of the frequency.
For solving the problem, the present invention adopts following technical scheme:
A method of testing for filament cutter chopping effect, comprises the following steps:
1) make the standard testing body of filament cutter measure of merit, standard testing body, by silica gel and iron powder Homogeneous phase mixing, is made into Chinese chess shape, and single test body contains the magnetic material of 10%-80%, and the silica gel of 20%-90%, rubber or latex class material;
2) under filament cutter duty, by standard testing body by operating filament cutter, the standard testing body cut out all is taken out with powerful magnet;
3) to the standard testing body cutting rear taking-up, vernier caliper is used to measure average thickness, judge the actual tobacco cut width of pipe tobacco, judge filament cutter width control system accuracy, observing the standard testing body smooth cut degree after cutting, judge knife blade of filament cutter sharpness, calculating loss in weight ratio before and after the chopping of standard testing body by weighing, judge chopping process loss rate, concrete account form is:
1. the actual tobacco cut width of pipe tobacco=cut out standard testing body thickness mean value;
2. pipe tobacco width criteria deviation=ξ
1× cut out standard testing body thickness standard deviation, wherein, ξ
1for correction factor, computing method are:
ξ
1=pipe tobacco width criteria deviation/cut out standard testing body thickness standard deviation;
3. chopping process loss rate=ξ
2× (cutting out standard testing body total amount)/cut front standard testing body total amount, wherein, ξ
2for correction factor, computing method are:
ξ
2the proportion of goods damageds that=actual test the proportion of goods damageds/try by standard testing body examination obtain.
Further, the weight of described test body is 50g and is made up of the iron powder of 35% and the silica gel of 65%.
According to research, (not more allowing blade replacement, emery wheel in filament cutter equipment state not change situation, or equipment does not break down), filament cutter running status is stable, and cigarette (stalk) quality state cut out also is stable, therefore, sampling detects the method cutting out tobacco quality state, can replace by evaluating filament cutter duty, and, by evaluating, filament cutter duty is more accurate, science, and operation is succinct.Filament cutter duty is evaluated, it is the test body using the shapes such as spherical, bar-shaped, the pie that is made into containing the silica gel of magnetic material, rubber, newborn gelatin substance, by operating filament cutter, then the test body cut out is collected, according to thickness, smooth cut degree, the test body loss in weight of the test body cut out, evaluate the tobacco cut width accuracy in filament cutter test process, blade sharper degree, chopping loss.
The invention has the beneficial effects as follows: it is more accurate that pipe tobacco width evaluates result of determination, due to testing standard shape rule, according to the standard body thickness cut out, pipe tobacco width representativeness is increased greatly, more can accurate evaluation filament cutter pipe tobacco width control system state; Testing result representativeness increases, by evaluating filament cutter duty, and can more material chopping quality state between accurate evaluation equipment stationary phase; Testing process is succinct, and detect data from being sampled to, need about 10 minutes consuming time of a skilled testing staff, step is simpler; The detection frequency is low, according to filament cutter operation characteristic, during equipment stable operation in (general 12 hours), only needs test evaluation 1 time.
