Tissue measurer for thickness and tissue method for measuring thickness
Technical field
The present invention relates to the structure and the use of the detecting instrument of family expenses tissue, toilet paper.
Background technology
In tissue manufacturing enterprise, always be to adopt special-purpose paper and Board thickness measuring instrument, (GB/T451.3-2002) tests the thickness of tissue, toilet paper according to national standard.But national standard (GB/T451.3-2002) relatively is fit to test thickness is high, product is solid, the material tightness is high paper and board product; Because the pressure that its regulation loads on the sample is 100kPa; So and be not suitable for the thickness measuring of tissue, toilet paper: because tissue, toilet paper have the characteristic of its soft fluffy; As load bigger pressure (about 2 kiloponds are defeated piece); With directly having eliminated its fluffy characteristic, can not reflect product characteristic, make test result lose practical significance.
Summary of the invention
The tissue measurer for thickness and a kind of tissue method for measuring thickness that the purpose of this invention is to provide a kind of suitable test tissue, toilet paper.
Tissue measurer for thickness of the present invention comprises base, time measurement block, last sounding rod and the thickness indicating gauge of belt supporting frame; It is characterized in that measurement block is fixed on the base down, the carrying plane of level is arranged on it; The quality of last sounding rod is 90 grams; Last sounding rod is slidably mounted in the guide hole of support and can moves up and down along guide hole; There is the last measurement plane parallel with the carrying plane of following measurement block the lower end of last sounding rod, and the relative area of last measurement plane and carrying plane is 200 square millimeters; The thickness indicating gauge is fixed on cantilever tip, the last end in contact of the probe of thickness indicating gauge and last sounding rod.
Tissue method for measuring thickness of the present invention may further comprise the steps:
1. falling sounding rod makes the last measurement plane of sounding rod contact with the carrying plane of following measurement block;
2. adjusting the thickness indicating gauge, to make its reading be zero;
3. tissue to be measured flat build up total number of plies be 12 aspects long-pending be 100 square centimeters sample;
4. rise and go up sounding rod, on the carrying plane of measurement block, fall sounding rod to sample under moving into sample, read and write down the reading of thickness indicating gauge when testing 10 seconds with the speed that is lower than the 3mm per second;
5. respectively in the 4. step operation of the diverse location triplicate of sample, get the mean value of three read-records, according to step 3. in the stacked system of sample try to achieve the thickness of tissue to be measured.
The present invention has cancelled the heavily about 1.8 kilograms briquetting on traditional paper and Board thickness measuring instrument; The pressure that sample is born eases down to deficiency so that sample is obviously compressed; Under the prerequisite of keeping the tissue grown form, obtain objective believable measurement result, for the standardization production of tissue production provides accurate data.
The present invention is suitable for and detects the consumer paper products that all size tissue, toilet paper etc. have sandwich construction, soft fluffy.
Description of drawings
Fig. 1 is the structural representation of tissue measurer for thickness of the present invention.
Embodiment
Referring to Fig. 1, tissue measurer for thickness of the present invention comprises base 1, following measurement block 2, goes up sounding rod 3 and thickness indicating gauge 4.
The base 1 of cast iron has extended upward support 11, and the middle part of support 11 is fixed with axle sleeve 13, and vertical guide hole 14 is arranged in the axle sleeve 13; Last sounding rod 3 usefulness metals are processed, and its quality is 90 grams, and last sounding rod 3 is installed in the guide hole 14, and guide hole 14 and sounding rod 3 all pass through finishing and both be slidingly matched, and sounding rod 3 can move up and down along guide hole 14 smoothly; There is measurement plane 31 lower end of last sounding rod 3, and the area of measurement plane 31 is 200 square millimeters; Following measurement block 2 usefulness metals are processed; Following measurement block 2 is fixed on the base 1; The carrying plane 21 that has the measurement plane 31 with last sounding rod 3 lower ends to be parallel to each other on it, the area of carrying plane 21 are greater than the area of measurement plane 31, and the profile of carrying plane 21 contains the profile of measurement plane 31; Thickness indicating gauge 4 can be pointer instrument or digital instrument, and thickness indicating gauge 4 is fixed on support 11 tops by screw 12, and the probe 41 of thickness indicating gauge 4 contacts with the last transverse plane 32 of last sounding rod 3.The leverage of on guide hole 14 next doors of base 1, being made up of lever 15 and fulcrum 16, the end of lever 15 stretches into the through hole of sounding rod 3 upper ends, presses lever 15 and just can promote sounding rod 3.
Adopt the described tissue measurer for thickness of Fig. 1 when carrying out the tissue thickness measure, and follow following steps and measure:
1. falling sounding rod 3 makes the measurement plane 31 of sounding rod 3 contact with the carrying plane 21 of following measurement block 2;
2. unclamp screw 12, it is the screw 12 of screwing again after zero that adjustment thickness indicating gauge 4 makes its reading;
3. flat to build up total number of plies be 12 layers tissue to be measured, and area is 100 square centimeters a sample 26;
4. pull lever 15 downwards, rise last sounding rod 3, on the carrying plane 21 of measurement block 2, fall above sounding rod 3 to the sample 26 under moving into sample 26, read and write down the reading of thickness indicating gauge 4 when testing 10 seconds with the speed that is lower than the 3mm per second;
5. respectively in the 4. step operation of the diverse location triplicate of sample 26, get the mean value of three read-records, according to step 3. in the stacked system of sample 26 try to achieve the thickness of tissue to be measured.
