Problems solved by technology

Due to the large amount of real-time data of photoelectric detection, the final result obtained by the instrument is the average value of multi-point measurement, and the laser controller can control the amount of process data received per second; The stability of the measurement results cannot be guaranteed after being adsorbed after one rotation to complete the normal measurement, so the length measurement device cannot judge whether the multi-point measurement affects the final measurement result
At present, there is no good method for judging the verification method of the influence degree of multi-point measurement when measuring the length of cigarettes and filter rods

Embodiment 1

[0021] Such as Figure 1~Figure 3 Shown is a standard device for measuring the length of cigarettes and filter rods. The device includes a frame and a CCD caliper 3. The frame 1 includes two legs 1 and a mounting plate 2. The two legs 1 are located on the mounting frame. On both sides of the board 2 , two legs 1 are made of aluminum profiles. The bottom of the legs 1 is provided with a bottom profile 11 , and the bottom profile 11 and the legs 1 are fixed by a connecting piece 12 . There are two CCD calipers 3, which are installed on both sides of the horizontal plate 2 facing vertically respectively, and the middle position of the horizontal plate 2 is provided with a right-angle bracket 4. Such as Figure 4 , Figure 5 As shown, the bottom of the right-angle bracket 4 is provided with a DC speed regulating motor 5, and the upper part is provided with a rotating platform 6. The DC speed regulating motor 5 is connected with the rotating platform 6 through a coupling 10, and ...

Embodiment 2

[0023] "GB22838.2-2009 Determination of Physical Properties of Cigarettes and Filter Rods Part 2: Length Photoelectric Method" stipulates that multi-point measurement should be carried out on the end of the sample. The data measurement system can make statistics on the data of each measurement point and use the arithmetic mean The value gives the sample length value. The data volume of the multi-point measurement may affect the accuracy of the length measurement. According to the principle of the length detector, the amount of multi-point measurement data is determined by the measurement frequency of the caliper itself and the rotation speed of the sample.

[0024] In this method, the sample is fixed in the clamping device, and the sample is always rotated at a constant speed during the measurement process, which can ensure the stability of each repeatability, and at the same time collect all the electrical signal data during the continuous rotation process. By adjusting the ...

Abstract

The invention relates to the field of testing of cigarette and filter stick length, particularly to a method for verifying multipoint measurement influence in cigarette and filter stick length measurement. In the method, a sample position in a measurement process of each time is kept unchanged, thereby ensuring stability of sample measuring results. At the same time, sample rotation speed in the measurement process can be adjusted, i.e., a data volume of multipoint measurement when the sample rotates for one circle can be adjusted, and measured data of laser are obtained uniformly. Through the abovementioned technical scheme, during repetitive measurement, the sample position does not change, on the premise that stability of the measuring results is guaranteed, data of multipoint measurement under different frequencies can be obtained through adjustment of the sample rotation speed, finally an average value of all the data is calculated, thereby obtaining an instrument result of the length, and the method has the characteristics of reliable measuring method and simple calculation.

Description

technical field [0001] The invention relates to the field of testing the length of cigarettes and filter rods, in particular to a method for verifying the influence of multi-point measurement when measuring the length of cigarettes and filter rods. Background technique [0002] The mainstream cigarette and filter rod length testing devices currently in use all adopt the principle of photoelectric detection. Due to the large amount of real-time data of photoelectric detection, the final result obtained by the instrument is the average value of multi-point measurement, and the laser controller can control the amount of process data received per second; The stability of the measurement result cannot be guaranteed if it is adsorbed after one revolution to complete the normal measurement, so the length measurement device cannot judge whether the multi-point measurement affects the final measurement result. At present, there is no good method for judging the verification method o...
