The surface linear speed of front roller is equal to the surface linear speed of the suction pressure axis, and they rotate toward the same direction. The merits of this invention are as fellows, 1. The yarn is homogeneous and the quality is stable. 2. The front roller is forced by two different forces from different direction of the two drafting jaw lines, and this forces the axial lead of the pasting rod on the front roller automatically parallels with the axial lead of the front roller, so it can improve the stability of the spinning and decrease the required precision of the cradle.
Description
Technical field
The present invention relates to a kind of spinning machine with accumulator.
Background technology
In spinning machine, when one the drawn fiber bar when front roller obtains twisting to the downstream, then can produce so-called spinning triangular zone at the right jaw line of front roller, spinning triangular zone causes spinning back fibrous inside tension very inhomogeneous, has reduced the intensity of resultant yarn.For this reason, set up the fibre strand integrated composite device of a so-called band negative pressure in the draw zone downstream of drafting device for spinning machine, fiber strip is through the conveying of accumulator, boundling or set on accumulator, ribbon no longer produces spinning triangular zone when leaving accumulator like this, and the filoplume of ribbon reduces through the negative pressure-pumping of accumulator and is integrated into equably in the ribbon, makes that resultant yarn is more even, the intensity of ribbon increases.
The fibre strand integrated composite device of above-mentioned band negative pressure mainly contains two kinds of forms at present, first kind is that the negative pressure tube-surface that has negative pressure trough is with flexible ventilative cycloconveyor belt, ventilative cycloconveyor belt is carried spinning fiber, spinning fiber produces boundling or set under the effect of spinning fiber in negative pressure through negative pressure trough the time, second kind with major diameter mesopore roller, major diameter mesopore roller peripheral surface is made the ventilative aperture of high density, below these apertures, insert the air-deflector that has negative pressure trough, carry spinning fiber by the ventilative aperture position of the high density of major diameter mesopore roller, spinning fiber spinning fiber under the effect of negative pressure produces boundling or set during through negative pressure trough, has formed the spinning machine of two types band negative pressure accumulator thus.
First type spinning machine, with Chinese patent literature CN1367281A is closely spinning of the ventilative cycloconveyor belt form of having of representative, it reduces than existing spinning machine spinning filoplume, resultant yarn is even, ribbon intensity increases, and relatively low to existing homemade spinning machine repacking cost, applies easily, but because the ventilative cycloconveyor belt of its negative pressure accumulator is easily blocked, air penetrability is influenced and cause spinning quality to descend.In order to improve spinning quality stability, must regularly clean and change ventilative cycloconveyor belt, management expectancy and maintenance cost have been increased, therefore spinning quality is a curve, spinning quality was the poorest when ventilative cycloconveyor belt will clean, and it is best that ventilative cycloconveyor belt has just cleaned the back spinning quality.
Second type spinning machine, with Chinese patent literature CN1122385A is the spinning machine that peripheral surface is made the major diameter rigidity mesopore roller of the ventilative aperture of high density that has of representative, though its spinning filoplume reduces, resultant yarn is even, and the intensity of ribbon increases, and spinning quality is stable, but because it can only become one with special spinning machine in the existing Switzerland, to existing homemade spinning machine repacking difficulty, so its apparatus expensive, apply difficulty.
The spinning machine of above-mentioned second type also has a kind of mode, as be disclosed in spinning machine among the Chinese patent literature CN1394242A, see Fig. 4, it increases the bottom roll 19 of a suction roller 15 and velamen driving on common spinning machine, and suction roller 15 is metal or rigid body, in order to guarantee that jaw 12 and jaw 13 have certain pressure that contacts, also disposed elasticity clad 20 and 21 respectively at roller 8 and roller 19, see Fig. 4 for details.Though as if this technical scheme can be applicable to the transformation of existing spinning machine, but in concrete enforcement, also there is following deficiency: at first all be to form in roller 8 and the spinning machine of roller 19 by more than 100 end to end roller serial connection in routine, reach more than 30 meter, when its elasticity clad 20 and 21 wearing and tearing need reparations, it is very uneconomical to waste time and energy.They are two years old, suction roller 15 is mechanisms of a more complicated, wherein be mounted with an adjustable inspiratory component 17, inspiratory component 17 has suction slot 18 and requires to guarantee at gathering correctly location, district 11, inspiratory component 17 also will be connected with air intake duct 16, air intake duct 16 will be connected with the spinning machine air-suction channel, so complicated suction roller 15, realize this programme and spinning smoothly, suction roller 15 must be the moving component that the P direction can be mentioned and can depress, otherwise initial difficulty fast more just can't connect or spin when in a single day yarn has broken, when being wrapped on the roller 8, yarn can't remove residual yarn, have a strong impact on frequent spinning, yet suction roller 15 is designed to moving component, be installed on the reel cage of spinning machine, not only complex structure cost height but also poor reliability, because air intake duct connector of every motion is all wanted bending once, easily cause leakage and location inaccurate, the also necessary particular design manufacturing of the reel cage of fixing in addition suction roller 15, to mention the bigger suction roller of weight 15 simultaneously can also crooked air intake duct connector.Its three, when the technical program was used to reequip homemade spinning machine, angle β and β ' can't guarantee between 58 ° to 70 °.If guaranteed that angle β and β ' are between 58 ° to 70 °, 22 positions of point of contact on the clad 21 of roller 19 when then yarn 14 is exported, clad 21 is generally elastomer making such as rubber, specific rigidity body suction roller 15 adsorptivities are stronger, make on the easier clad 21 that is entangled in roller 19 of yarn fibers, influence spinning quality.
Summary of the invention
Technical problem to be solved by this invention provides a kind of spinning machine with accumulator, and it can overcome the deficiency that existing rigidity mesopore roller type negative pressure accumulator spinning machine exists, and reaches the purpose of the existing homemade filament machine of convenient, low-cost repacking.
The present invention solves the problems of the technologies described above the scheme that is adopted:
A kind of spinning machine with accumulator, at spinning machine front roller and upper glue roller the negative pressure propeller boss that a rigidity mesopore peripheral surface is made the ventilative aperture of high density is set up in the place ahead, the air-deflector that has negative pressure trough is close to negative pressure propeller boss inwall, and the negative pressure trough of air-deflector is at the ventilative aperture of the high density of negative pressure propeller boss, it is characterized in that: described front roller upper glue roller presses when front roller forms drawing-off jaw line, the front roller upper glue roller presses and forms another jaw line in the surface of negative pressure propeller boss, the outer surface line speed of described front roller equals the linear velocity of negative pressure propeller boss outer surface, and to same direction rotation.
Compared with prior art, the invention has the advantages that:
1, the front roller upper glue roller has been realized the function of two aspects simultaneously, the front roller upper glue roller presses in front roller formation drawing-off jaw line, reach the purpose of front roller drawing-off spinning fiber, the front roller upper glue roller presses in the surface of negative pressure propeller boss formation jaw line simultaneously, reach effective control spinning fiber and enter the purpose of gathering the district, it is controlled fully that spinning fiber after the front roller drawing-off enters in the process of gathering the district spinning fiber like this, makes resultant yarn more even, and quality is more stable.
2, usually spinning machine front roller upper glue roller just forms drawing-off jaw line with front roller, realize the purpose of front roller drawing-off, when front roller upper glue roller and front roller form single jaw line, the front roller upper glue roller only is subjected to the active force of single jaw line, can not force front roller upper glue roller axial line parallel fully with the front roller axial line, therefore, the depth of parallelism of front roller upper glue roller axial line and front roller axial line will rely on the reel cage precision that grips the front roller upper glue roller to guarantee, the national Specification reel cage grips the front roller upper glue roller and requires the depth of parallelism of front roller upper glue roller axial line and front roller axial line in 0.7mm, the depth of parallelism of pressing spinning requirement front roller upper glue roller axial line and front roller axial line is more little, then resultant yarn is even more, quality is more stable, the inconsistency of reel cage precision has a strong impact on spinning quality, the present invention is designed to the front roller upper glue roller and presses when front roller forms drawing-off jaw line, the front roller upper glue roller presses in another jaw line of negative pressure propeller boss surface formation, effect when the front roller upper glue roller is subjected to two jaw lines from two power of different directions, force front roller upper glue roller axial line and front roller axial line auto-paralleling, greatly improved spinning quality stability, reduced requirement the reel cage precision.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of spinning machine with accumulator, keep existing homemade spinning machine drafting part three rollers 2,3,5 invariant positions, set up the negative pressure propeller boss 7 that a rigidity mesopore peripheral surface is made the ventilative aperture of high density in front roller 5 the place aheads, the air-deflector 8 that has negative pressure trough 9 is close to negative pressure propeller boss 7 inwalls, the negative pressure trough 9 of air-deflector 8 is at the ventilative aperture of the high density of negative pressure propeller boss 7, outer surface 6 linear velocities of spinning machine front roller 5 equal the linear velocity of negative pressure propeller boss 7 outer surfaces 29, both linear velocity errors are less than ± 1%, and the rotation of same direction.
Described front roller upper glue roller 15 presses in front roller 5 formation drawing-off jaw lines 14, front roller upper glue roller 15 presses the surface formation jaw line 17 of negative pressure propeller boss 7 simultaneously, spinning fiber 1 is in tensioning state through jaw line 14 to jaw line 17, control the motion of spinning fiber 16 effectively, spinning fiber 1 had been eliminated the existence of free yarn before entering cluster area 27 like this, because rubber roll 15 is subjected to the effect of the both direction power of jaw line 14 and jaw line 17, force rubber roll 15 axis parallel fully with front roller 5 axis, the elimination of so free yarn and rubber roll 15 are with respect to the raising of front roller 5 depth of parallelisms, make resultant yarn more even, spinning quality is more stable.
Above-mentioned negative pressure propeller boss 7 downsides also have a resistance twist rubber roll 18, resistance twist rubber roll 18 presses the surface 19 of propeller boss 7, resistance twist rubber roll 18 is 38～48mm with the centre-to-centre spacing A of rubber roll 15, in order to guarantee to spin angle β and β ' between 58 ° to 70 °, guarantee that simultaneously spinning fiber 10 must be tangential on 30 places, surface of negative pressure propeller boss 7, the point of contact extension line of spinning fiber 1 and roller 2 and roller 3 is to negative pressure propeller boss 7 apparent height h=10～20mm, the best is 13～18mm, negative pressure propeller boss 7 diameter D=Φ 35～Φ 55mm, negative pressure propeller boss 7 diameters the best is D=Φ 45+3mm.
Because 7 of this programme negative pressure propeller boss play the effect of gathering of spinning fiber, the drawing-off of spinning fiber is realized by front roller, therefore the pressure of 15,18 pairs of negative pressure propeller boss 7 of rubber roll can be less relatively, negative pressure propeller boss 7 can adopt engineering plastics to make, the high density aperture die forming of breathing freely picks up several times with the ventilative aperture cost decline of metal propeller boss machining high density relatively.
Add travelling gear by front roller 5 and drive 7 rotations of negative pressure propeller boss, twizzle 20, rings 23, steel traveler 22, ring rail 24, spindle 25, rail 26, frame 21, rubber roll 11,12 and cushion rubber 4,13 etc. keep former spinning machine structure constant.
Fig. 3 is the structural representation by the spinning machine behind the existing homemade spinning machine of Chinese patent literature CN1122385A transformation.The position of the front roller 5 of homemade spinning machine as shown in Figure 3, if negative pressure propeller boss 7 replaces front rollers 5, then skew has taken place in the center of front roller 5, this will do bigger change (comprising the change of transmission mechanism) concerning homemade spinning machine.In order to guarantee the control to spinning fiber 28, the free yarn 28 of spinning fiber is short more good more, and resultant yarn is even more, spinning quality is stable more, so h ' is necessary for zero.In order to guarantee that cluster area 27 has enough spaces, A '=38～48mm, since homemade existing spinning machine twizzle 20, spindle 25 with respect to the position of frame 21 and before, during and after 45 ° in the angle of cut on three roller center line lines and frame 21 planes, because the die is cast for the project organization reason, change it and then need change these parts, cause improvement cost to rise.If do not change then spinning fiber 10 must be tangential on rubber roll 31 places with rubber roll 18, be subjected to the restriction of rubber roll 31.Because rubber roll is compared easier absorption spinning fiber with rigid member negative pressure propeller boss 7, therefore causing the spinning fiber part to be taken away by rubber roll absorption is wrapped on the rubber roll, have a strong impact on spinning quality, so Chinese patent application number 95107074.6 schemes are reequiped difficulty concerning homemade spinning machine.And for the spinning machine of special company in the Switzerland, angle of cut on three roller center line lines and frame 21 planes is 30 ° before, during and after it, twizzle 20, spindle 25 move many with respect to the position of frame 21 to directions X, therefore be fit to enforcement, the above-mentioned defective of mentioning when existing homemade spinning machine is reequiped can not take place yet by Chinese patent literature CN1122385A.
