Detailed description of the invention
Referring to Fig. 1 ~ 5, the large grasping force roller of one that the utility model relates to, grip apart from spinning apparatus greatly, described device includes reel cage and drafter, described drafter includes front leather roller 1.1, front roller 1.2, medium rubber roller 2.1, middle roller 2.2, rear roller 3.1 and rear roller 3.2, on described medium rubber roller 2.1 and middle roller 2.2, be separately installed with pin 4.1 and downside pin 4.2, the iron core 1.1.1 diameter of described front leather roller 1.1 is 13mm, the thickness of the rubber rollers 1.1.2 of described front leather roller 1.1 is 8.5mm, the diameter of described front leather roller 1.1 is 13+8.5 × 2=30mm, the width of the rubber rollers 1.1.2 of described front leather roller 1.1 is 20mm, described reel cage applied pressure is 75N, the shore hardness of described rubber rollers 1.1.2 is 68 °, adopt the lower rubber of shore hardness, and increase the thickness of rubber rollers 1.1.2, therefore increased the contact area of front leather roller 1.1 and front roller 1.2, increase the area of its gripping surface, therefore can in the situation that reducing reel cage pressure, keep larger grasping force, and reduce after reel cage pressure, greatly reduce the consumption of electric energy, there is energy-conservation positive benefit.
Described upper pin 4.1 forms in jaw place reach the jaw of living, and this is because for selling 4.1 concordant with downside pin 4.2 in old technique jaw place, the jaw forming between upper pin 4.1 and downside pin 4.2 is dead jaw or hard jaw; If without spacing block, can not spin because going out hardhead, therefore nip gauge is wanted grasp bigger than normal; The utility model is because upper pin 4.1 is gone out downside pin 4.2 and had the concrete distance of 4mm(to adjust via actual conditions), the jaw forming between upper pin 4.1 and downside pin 4.2, for jaw or the soft jaw of living, also can spin without spacing block; Therefore nip gauge can less than normally be grasped;
, a kind of large grasping force roller of the utility model, grip in spinning method greatly, the forward setting distance of front leather roller 1.1 is X1 meanwhile, and the forward setting distance of medium rubber roller 2.1 is X2, and the distance of shaft centers between front roller 1.2 and middle roller 2.2 is D;
First forward setting distance and the attach ratios relation that grips distance are analyzed, definition leather roller diameter is r, roller diameter is R, in the time of roller preshoot X, the variation distance that grips distance is s, s/X=r/(r+R), so the variation that grips distance is apart from s=(r/(r+R)) X, because R approximates r, s=X/2, the half that the variation distance that grips distance is forward setting distance, this point is of great importance for the utility model, because in traditional handicraft, due to technology prejudice, all think that forward setting distance equals to grip the variation of distance, but, in fact, during due to roller preshoot, not only move horizontally, and because roller and roller are that arc surface contacts, roller has certain sinking, it has only rolled across a low-angle in whole preshoot process in cambered surface, therefore according to above-mentioned calculating, the half that is changed to forward setting distance that grips distance is more suitable, this adjustment to follow-up other relevant parameters has great directive significance,
Therefore,, in spinning method of the present utility model, grip apart from S=D+X1/2+X2/2;
Referring to Fig. 5 and Fig. 6, the utility model is carried out to one and specifically set forth, and contrast with common process, now:
In new technology, front leather roller 1.1 preshoot 4mm, medium rubber roller 2.1 preshoot 2mm, the distance of shaft centers between front roller 1.2 and middle roller 2.2 is 45mm;
In old technique, front leather roller 1.1 preshoot 2mm, medium rubber roller 2.1 backlash 2mm, the distance of shaft centers between front roller 1.2 and middle roller 2.2 is 43mm;
Visible:
One, the gripping of new technology is apart from being: 45+4/2-2/2=46mm; The gripping of old technique is apart from being: 43+2/2+2/2=45mm; The gripping of new technology is apart from being better than old technique;
Two,, in the situation that gripping apart from increase, for the district of swimming, compared with old technique: new technology roller gauge has been amplified 45-43=2mm, the corresponding district of swimming increases 2mm; Upper pin preshoot from-2 becoming+2, the district of swimming reduces 4mm; Front leather roller by+2 preshoots to+4 swim district increase (4-2)/2=1mm; Comprehensive above impact, the new technology district of swimming has reduced 4-2-1=1mm; Visible, in the situation that gripping apart from increase, the district of swimming has reduced on the contrary, therefore meets the requirement of spinning process completely;
Three, with old technique ratio, middle roller has increased 94-86=8 degree to the transmission cornerite of lower apron, has improved the sync rates of transmission accuracy and upper and lower apron;
Four, because upper pin preshoot makes the middle iron roll 0.3mm that sunk, this just makes apron up and down between middle iron roll, middle roller and lower Xiao rear portion form the curved surface of a sinking 0.3mm, strengthen main drawing area postmedian friction field, be conducive in drawing-off, postmedian fiber effectively be controlled, Fiber Velocity point is more moved forward, improve spinning yarn quality.
Five, due to more preshoot of front leather roller, non-twist triangle is further reduced, be conducive to reducing resultant yarn filoplume, reduce broken end.
Six, apron transmission is subject to the variation of force direction, common process moves 2mm after due to top roller, and the direction of apron driving force is upper left side direction, and this just makes upper leather ring have a trend of upwards walking, easily cause upper leather ring floating, be unfavorable for the control of upper and lower apron to fiber; And the direction of new technology apron driving force is lower left direction, when work, upper and lower apron is close to, and is conducive to the control to fiber;
Seven, soft or hard jaw, the difference of jaw anyway.The old technique jaw upper and lower Xiao Pingqi in place, the jaw forming between upper and lower Xiao is dead jaw or hard jaw.If without spacing block, can not spin because going out hardhead, therefore nip gauge is wanted grasp bigger than normal; New technology is lower Xiao 4mm because upper Xiao goes out, and the jaw forming between them, for jaw or the soft jaw of living, also can spin without spacing block; Therefore nip gauge can less than normally be grasped;
Eight, nominal length of floating area and actual length of floating area, the upper and lower Xiao Pingqi of old technique, load onto the openning that has opened a spacing block thickness after spacing block between upper and lower Xiao and deduct upper and lower apron thickness, bigger than normal if spacing block is selected, actual length of floating area is greater than nominal length of floating area; And new technology fiber strip passes through upper Xiao forward position all the time, length of floating area is unchanged.
The comprehensive large above feature gripping apart from new technology, in spinning process, we just can adopt larger roving twist factor, less first break draft multiple and nip gauge to increase the internal friction between fiber, make resultant yarn have raising by a relatively large margin at stability indicator (cvb as dry in bar, DR value), length thickness joint, cotton knot, filoplume and winder yarn defect etc.Meanwhile, due to large grip apart from spinning technique have grip apart from large, the district of swimming is little, can spin textile general comb until each veriety such as chemical fibre and need not change drawing-off and space, yarn quality all remains on higher level.The many kinds of modern textile factory, small lot, fast requirement of delivering goods are adapted to;
Carry out after above-mentioned amendment, in spinning process, can also carry out following optimizing and revising to other parameters, require to reach best knitting technology:
1, match sieve compact spinning guiding leather roller and dominant draft roller all adopt large grasping force roller, and the diameter of guiding leather roller adopts ∮ 28mm, and dominant draft leather roller diameter adopts ∮ 30mm; Commonly spin, match sieve and spin dominant draft roller and adopt ∮ 30mm large grasping force roller;
2, main drawing area grips distance: match sieve compact spinning main drawing area adopts 46.5mm; Common spin, match sieve spin adopt 46mm;
3, dominant draft roller position: match sieve spins, matches sieve compact spinning dominant draft roller+1mm; Common spinning+4mm;
4, middle iron roll, rear roller position: unified is+2(preshoot), 0(is constant);
5, back zone grips distance: unified is 70mm;
6, reel cage pressure: match sieve compact spinning 40N, 75N, 90N, 100N; Match sieve spins, the old technique match of the common 75N of spinning, 90N, 100N(sieve compact spinning 50N, 150N, 140N, 150N; Match sieve spins, the common 150N of spinning, 140N, 150N).
7, adopt larger roving twist factor; Viscose products can increase 10%, and Pure cotton Product can increase 10-20%.
8, adopt less spun yarn first break draft (≯ 1.2) and tighter embedding mouth to space (comparing conventional little one grade of configuration).
After Overall Reconstruction, can reach following result of use:
1, reel cage pressure can alleviate half, is alleviated to 75N by 150N;
2, complete machine power consumption reduces by 8-10%; In 30 yarns, ten thousand ingot year 10.8 ten thousand yuan of power cost savings.Be calculated as follows: 10.8 ten thousand yuan/year of 1500 tons × 0.16 ten thousand yuan × 45% × 10%=;
3,, under conventional spinning condition, roller returns the mill cycle and can extend to 12 months by 4 months; Spin, match under sieve compact spinning condition at match sieve, roller returns the mill cycle and can extend to 8 months by 2 months; The consumption of roller is 1:4; Within 1 year, consume a roller in the every ingot of the match old technique of sieve compact spinning, spend 3.5 yuan; New technology consumes a roller for 4 years, and every spends 4 yuan, and every ingot spends 4/4=1 unit every year.Every ten thousand ingot saving (3.5-1) × 10,000=2.5 ten thousand yuan;
Its mechanism is as follows: large grasping force roller is because its rubbing surface length is long, and grasping force is large, therefore Draft Effect very high (approaching 100%).Fiber strip greatly reduces with respect to the amount of movement on roller surface, and therefore the wearing and tearing on roller surface greatly alleviate.
4, component wear is little; New car is enabled the nondiscolouring in a year of headstock draft gear oil; Roller iron core can exempt to refuel for 5 years;
5, stable yarn quality, index level is high---1., in stability indicator concretely:, the dry cvb of bar can be controlled in 2%; 1.5mDR value is in 10; The dry platform of bar is poor little: in life cycle, the diameter range of large grasping force roller is 29.2-30mm, and in the situation that using Spring cradle, length of floating area changes little.And old technique leather roller diameter scope is 28.2-30mm, length of floating area changes greatly, causes the dry platform of bar poor large; 2., details can reduce 30%; 3., slubbing can reduce 15%; 4., cotton knot can reduce 30%; 5., resultant yarn filoplume reduces 30%; 6., total yarn defect can reduce by 20%;
