9, camera lens support frame 8 is fixed by zoom magnifying glass 9 with method of clamping, so that zoom magnifying glass 9 is not susceptible to fluctuate, structure letter
It is single, it is practical.
The upper surface of zoom magnifying glass 9 is equipped with dial 10, and zoom magnifying glass 9 is equipped with zoom knob 11 and to focus knob
12.Zoom knob 11 realizes 2 times to 16 times Stepless transmissions, is overlapped the graduation mark on camera lens with fabric warp or weft yarn；Focusing
Knob 12 adjusts 9 focal length of zoom magnifying glass, makes fabric imaging clearly.
Button 25 is also equipped in rack 2, button 25 shares 4, and both the above button 25 is for controlling longitudinal movement
The forward and reverse of motor 16；Following two button 25 is used to control the rotating forward or reversion of transverse mobile motor 5, facilitates control
Transverse shifting frame 3 and longitudinal movement frame 13, of simple structure and strong practicability.
In measurement process, the big consistency of fabric to be measured is estimated first, fabric is then laid in fabric placement platform
On 17, fabric cover 18 is covered, the visual fabric area size of cover board mirror 24 is 5cm × 5cm.For convenient for fixed fabric, it is desirable that adopt
Fabric size to be measured is greater than equal to 17 size of fabric placement platform (65mm × 70mm).Start instrument after fixing fabric
Device adjusts two position indicator pointers on cover board mirror 24 and returns to initial position.Rotate the zoom knob 11 on zoom magnifying glass 9 and focusing
Knob 12 keeps 9 graduation mark of zoom magnifying glass clear with fabric yarn and is completely overlapped；By left and right adjusting button 25, adjust
The left-right position of camera lens；By front and back regulation button 25, the front-rear position of fabric placement platform 17 is adjusted.Repeat above three behaviour
Make, so that camera lens and fabric to be measured is precisely coincident, fabric should be made to be located at 9 camera lens of zoom magnifying glass always in entire adjustment process
In.After adjusting, start to measure.For measuring warp yarn, zoom magnifying glass 9 is moved to by button press 25
Far Left towards instrument direction is overlapped the warp of fabric with 10 high scale of dial, adjusts pointer regulation knob, records mirror
Head in last root be overlapped with 10 high scale of dial through line position, then button press 25, make zoom magnifying glass 9 move right
It is dynamic, it repeats the above process, counts the radical of yarn in mobile full lens number and single camera lens, be discontented with entire mirror for the last time
When head, the yarn radical in camera lens at this time is counted.In counting process, according in standard GB/T4668-1995 when being discontented with one
It is required that being counted.It is finally calculated according to formula, finds out final yarn count, calculation formula are as follows:
Final yarns number=mono- camera lens yarn radical × camera lens completely moves remaining yarn in number+the last one camera lens
Line radical
Similarly, weft yams can be measured, only zoom magnifying glass 9 is adjusted to suitable position and just no longer moves at this time, and
It is to complete to measure by adjusting fabric placement platform 17.After all counting, the yarn radical of conversion to 10 centimetre lengths is
Can calculate fabric through close and filling density.
In above-mentioned measurement process, the amplification factor range of zoom magnifying glass 9 is 2 times to 16 times, and zoom magnifying glass 9 amplifies
Times number interval and the corresponding relationship of the measurement range of the yarn radical per cm of fabric to be measured are as shown in table 1 below.In the present invention
Instrument is primarily adapted for use in common yarn radical per cm greater than 10 fabric less than 80.
The selection of 1 zoom magnifying glass of table, 9 multiple and fabric yarn radical relation table to be measured
It is per cm to measure based on the mobile number corresponding relationship explanation of amplification factor and camera lens of the table 1 to zoom magnifying glass 9
For the fabric warp of 20 piece/centimetre of yarn radical.
1, eye estimate fabric to be measured warp radical per cm is 20 pieces/centimetre between 40 pieces/centimetre first, is then looked into
It sees the selection of 9 multiple of zoom magnifying glass and fabric yarn radical relation table to be measured, needs to adjust 9 amplification factor of zoom magnifying glass at this time
Between 4-8 times；
2, fabric to be measured is fixed on fabric placement platform 17 by operation.Then adjustment 9 zoom of zoom magnifying glass rotation
For button 11 until only remaining an one thread in camera lens between two graduation marks, amplification factor is 4 times at this time, while adjusting zoom magnifying glass
9 pairs of focus knobs 12, clearly indicate yarn in camera lens.
3, left and right adjustment zoom magnifying glass 9 or front and back adjust fabric placement platform 17, make fabric warp and 10 quarter of dial
Degree is overlapped, and makes one end of scale and the coincident of fabric.
4, after fabric warp is overlapped with 10 scale of dial, start to measure by operation, count the complete of movement respectively
Whole yarn radicals in camera lens number and the last one imperfect camera lens.10 full scale of dial in zoom magnifying glass 9 at this time
For 30 scales, 3 full lens and an imperfect camera lens are moved altogether, in total the last one camera lens of yarn radical=30 × 3+
Leftover yarn radical.Be converted to yarn radical in 10 centimetres again, can calculate fabric through close.
Similarly, the corresponding relationship of other amplification factors and the mobile number of camera lens can be calculated.
The above is only specific embodiments of the present invention, but technical characteristic of the invention is not limited thereto.It is any with this hair
Based on bright, to solve essentially identical technical problem, essentially identical technical effect is realized, made ground simple change, etc.
With replacement or modification etc., all it is covered by among protection scope of the present invention.
