Abstract
The utility model provides a circumferential dilution rate instrument which comprises a clamper, a laser transmitter, a laser receiver and a circumferential rotating disc. The circumferential rotating disc drives the clamper to rotate; the clamper drives a cigarette to be measured to rotate; the laser transmitter and the laser receiver are used for measuring the diameter of the cigarette to be measured; and the circumferential rotating disc is fan-shaped with a central angle smaller than 165 degrees. Through changing the central angle of the circumferential rotating disc, the instrument can basically solve the problems of the VF-03 circumferential dilution rate instrument such as large fluctuation of circumferential measurement and large standard deviation. Meanwhile, due to the change of the structure of the circumferential rotating disc and no damage to the structure of the prior instrument, the detecting principle of the prior instrument is not changed and the cost is lower.
Description
Technical field
The utility model relates to a kind of circumference dilution rate instrument, particularly a kind of circumference dilution rate instrument that can make tested cigarette Rotate 180 ° and its diameter is measured.
Background technology
VF-03 circumference dilution rate instrument is a tobacco instrumentation of measuring cigarette circumference and dilution rate.See also Fig. 1, it is the structural representation of circumference dilution rate instrument.Described circumference dilution rate instrument is by clamper 1 fixing cigarette to be measured, and in the prior art, the employing central angle is 180 ° a circumference rotating disc 2, as shown in Figure 2.During measurement, drive the cigarette rotation by circumference rotating disc 2, in rotary course, the signal section that generating laser 3 sends is received by laser pickoff 4, can measure the diameter of cigarette to be measured thus.See also Fig. 3, when not rotating (being 0 °) at circumference rotating disc 2, the diameter of measuring cigarette to be measured is X
1, when circumference rotating disc 2 rotates 90 °, 180 °, 270 °, and 360 ° the time, can measure cigarette to be measured each diameter when variant state respectively, wherein, diameter is respectively X when 180 ° and 270 °
N-1And X
n, at last each value of measuring is averaged the diameter that can obtain cigarette to be measured.Yet, because cigarette to be measured and off-gauge circle, usually all be elliptical shape, thus, when 180 ° of circumference rotating disc 2 rotational angle less thaies (for example 160 °), this moment, measured value can exist than big-difference, with the value of measuring in the time of 0 ° as shown in Figure 4, obviously precision and the accuracy for guaranteeing to measure needs the circumference rotating disc to rotate complete 180 °.Yet, existing circumference dilution rate instrument is equiped with bearing 5 in the outside of circumference rotating disc, when the circumference rotating disc rotates to about 160 °, will can't continue rotation because of stopping of bearing 5, promptly be difficult to make the circumference rotating disc to rotate complete 180 °, the diameter of cigarette value fluctuation that causes this kind method to be measured thus is bigger, and then standard deviation is also bigger.
Therefore, how to solve the problem that has the existence of circumference dilution rate instrument now and become the technical task that those skilled in the art need to be resolved hurrily in fact.
The utility model content
When providing a kind of the measurement, technical scheme to be solved in the utility model can make tested cigarette rotation reach 180 ° VF-03 circumference dilution rate instrument.
A kind of circumference dilution rate instrument, comprise clamper, generating laser, laser receptacle and circumference rotating disc, described circumference rotating disc drives described clamper rotation, described clamper drives tested cigarette rotation, described generating laser and described laser pickoff are measured the diameter of tested cigarette, what wherein, described circumference rotating disc was a central angle less than 165 ° is fan-shaped.
Further, the central angle of described circumference rotating disc is 155 °-165 °.
Further, the central angle of described circumference rotating disc is 160 °.
The beneficial effects of the utility model are: can solve VF-03 circumference dilution rate instrument circumference at all and measure fluctuation greatly, the problem that standard deviation is big.Simultaneously, owing to only changed the structure of circumference rotating disc, do not destroy the structure of former instrument, also do not change the test philosophy of former instrument, cost is lower.

Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
The measuring principle of VF-03 circumference dilution rate instrument is to utilize clamper to clamp the cigarette rotation, and measures the diameter of cigarette by generating laser and laser pickoff.Wherein, VF-03 circumference dilution rate instrument has a circumference rotating disc, and the main effect of described circumference rotating disc is to drive the clamper rotation, thereby drives the cigarette rotation.For the circumference rotating disc that solves VF-03 circumference dilution rate instrument stops owing to being subjected to bearing, can't rotate to 180 °, can only rotate about 160 ° problem, it is as follows that the utility model improves the circumference rotating disc:
See also Fig. 4, the circumference rotating disc that Fig. 4 provides for the utility model, the circumference rotating disc that central angle is 10 ° a disk gained is respectively clipped at the circumference rotating disc two ends of prior art, be the circumference rotating disc that the utility model provides, the central angle that is about to the circumference rotating disc of prior art is reduced to 160 ° from 180 °, thereby has reduced the girth of circumference rotating disc.
See also Fig. 5, the synoptic diagram of the circumference rotating disc Rotate 180 that Fig. 5 provides for the utility model °, the circumference rotating disc girth that the utility model provides is less, and bigger revolution space is arranged.As can be seen from Figure 5, after having rotated 180 °, there is 20 ° clearance spaces in the not inswept zone of circumference rotating disc, can hold the bearing that the circumference rotating disc that originally stopped prior art continues rotation, therefore, the circumference rotating disc that provides of the utility model can Rotate 180 °.
Simultaneously, because the rotational speed of circumference rotating disc is constant, therefore, need to adjust the rotational time of circumference rotating disc, in the present embodiment, rotational time was adjusted into 1.6 seconds from 1.2 seconds, and it is known how to be adjusted into present technique field personnel, is not repeated.
The central angle of circumference rotating disc becomes that to change 160 ° into be preferred version, as long as behind the circumference rotating disc Rotate 180 °, its not inswept zone can hold the bearing that the circumference rotating disc that originally stopped prior art continues rotation and get final product.Therefore, the circumference rotating disc that provides of the utility model can be central angle less than 165 ° circumference rotating disc.Simultaneously, in order to promote the circumference rotating disc more expediently, the central angle of circumference rotating disc is good at 155 °-165 °.
For verifying the improved action of the circumference rotating disc that the utility model provides, used same ellipse bar to substitute cigarette, repeat ellipse bar is measured, below be that the data to same ellipse bar duplicate measurements compared before and after the circumference rotating disc improved:
Can see that after the improvement, standard deviation obviously reduces, the circumference rotating disc that the utility model provides has improved the accuracy of measurement of VF-03 circumference dilution rate instrument greatly.Simultaneously, owing to only changed the structure of circumference rotating disc, do not destroy the structure of former instrument, also do not change the test philosophy of former instrument, cost is lower.
Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only.Any modification or partial replacement that does not break away from the utility model spirit and scope all should be encompassed in the middle of the claim scope of the present utility model.
