The invention discloses a kind of big cornerites for spinning to hold drawing-off roller group, belongs to spinning equipment technical field.The gripping roller group is by gear-box and passes through driving shaft first nip roiler parallel with the axial direction that gear-box connects, the second nip roiler and third nip roiler composition.Wherein, first nip roiler, the second nip roiler and third nip roiler are distributed in isosceles triangle, first nip roiler is located at top, second nip roiler and third nip roiler are located at lower part, spinning enters from the second nip roiler or third nip roiler bottom has third nip roiler or the second nip roiler bottom to lay out after Ω shape routes bypass the first nip roiler, wherein, cornerite of the spinning through the first nip roiler is not less than 240 degree.The cornerite that big cornerite provided by the present invention holds roller group is big, and the curable grip of bigger is provided for spinning tow, can effectively improve draw ratio and tensile strength between nip roiler and solvent stretching-machine.
Description
Technical field
The present invention relates to a kind of big cornerites for spinning to hold drawing-off roller group, belongs to spinning equipment technical field.
Background technology
It is unusual the key link to carry out drawing-off in spinning production process, after spinneret.But due to existing between drafting machine
Certain distance, especially apart from it is larger when, spinning tow, due to discontinuity, is easy to tow occur to exist in drafting process
Drafting multiple is too small between drafting machine, the relatively low problem of tensile strength.Therefore, it is often protected in the prior art by means of nip roiler
Drafting multiple is demonstrate,proved, but nip roiler in the prior art mostly increases traction times in such a way that two nip roilers form nip roiler pair
Number, but the cornerite of this mode nip roiler is often smaller, exists and holds the limited defect of drafting force, and long range is stretched often
Enough draw ratios can not be increased.Meanwhile the quantity of required nip roiler often just may be implemented to hold at 5 or more and lead
Stretch function.Since nip roiler number is more, friction area can be increased, lousiness rate is caused to increase.Lead to strand quality degradation,
Product disqualification rate is very high.
Invention content
In order to solve the above technical problems, the present invention provides a kind of gripping roller group of big cornerite, the technical side taken is such as
Under：
The purpose of the present invention is to provide a kind of big cornerites for spinning to hold drawing-off roller group, which holds rod group
By gear-box 1 and by driving shaft first nip roiler 2 parallel with the axial direction that gear-box 1 connects, the second nip roiler 3 and third are held
Hold the composition of roller 4, wherein the first nip roiler 2, the second nip roiler 3 and third nip roiler 4 are distributed in isosceles triangle, the first nip roiler 2
In top, the second nip roiler 3 and third nip roiler 4 are located at lower part, spinning from the second nip roiler 3 or 4 bottom of third nip roiler into
Enter through Ω shape routes around being laid out by third nip roiler 4 or 3 bottom of the second nip roiler after the first nip roiler 2, wherein spinning is through the
The cornerite of one nip roiler 2 is not less than 240 degree.
Preferably, second nip roiler 3 is identical with the diameter of third nip roiler 4.
Preferably, second nip roiler 3, third nip roiler 4 are identical with the diameter of the first nip roiler 2.
Preferably, tow is more than 200 degree by the cornerite of the second nip roiler 3 and third nip roiler 4.
Preferably, second nip roiler 3 and plane where the axis of third nip roiler 4 are parallel to the ground.
Preferably, first nip roiler 2, the second nip roiler 3 are identical as the length and diameter of third nip roiler 4.
It is highly preferred that the length of first nip roiler 2 is 1200-1600mm, a diameter of 300-350mm.
The advantageous effect that the present invention obtains：
The cornerite that big cornerite provided by the present invention holds roller group is big, the curable grip of bigger is provided for spinning tow, simultaneously
Have the function of drawing-off, draw ratio and tensile strength between nip roiler and solvent stretching-machine can be effectively improved.
The quantity provided by the present invention for holding the gripping draw roll that roller group uses is few, it is only necessary to which three nip roilers can be realized
Drawing-off function.Effective drawing-off function could be realized by often requiring to use five or more nip roilers in the prior art.
Description of the drawings
Fig. 1 is the positive structure diagram of the gripping roller group of the present invention.
Fig. 2 is the overlooking structure diagram that the present invention holds roller group.
In figure：1, gear-box；2, the first nip roiler；3, the second nip roiler；4, third nip roiler.
Specific implementation mode
The present invention is described in further details below in conjunction with the accompanying drawings, but the limit described further below being not intended as to the present invention
It is fixed.
Fig. 1 is the positive structure diagram of the gripping roller group in a kind of preferred embodiment of the present invention.Fig. 2 is nip roiler of the present invention
The overlooking structure diagram of group.From Fig. 1 and Fig. 2 it is found that it is mainly by a gear-box 1 and to pass through biography that the big cornerite, which holds roller group,
Three nip roilers composition that moving axis is connect with gear-box 1.Three nip roilers are located at the same side of gear-box 1, and axial direction is parallel simultaneously
It is distributed in isosceles triangle.Superposed is the first nip roiler 2, and what it is positioned at lower part is the second nip roiler 3 and third nip roiler 4.Its
In, diameter, the second nip roiler 3 of the first gripping rod 2 are identical with the diameter of third nip roiler 4, and the length of all nip roilers is identical,
Length is 1500mm, the first nip roiler 2, the second nip roiler 3 and third nip roiler 4 a diameter of 350mm.
In spinning production process, spinning tow enters from the bottom of third nip roiler 4 to be held in roller group, by Ω fonts
After route bypasses the first nip roiler 2, is drawn by the bottom of the second nip roiler 3 and hold roller group.Wherein, spinning is held by first
The cornerite of roller 2 is 240 degree, and cornerite when by the second nip roiler 3 and third nip roiler 4 is all higher than 200 degree.For cornerite angle
Degree can be adjusted by angle when each diameter for holding rod and position and tow disengaging is arranged.To make second to hold
The cornerite bigger for holding roller 3 and third nip roiler 4 can properly increase height when tow disengaging, make on two bottom edges of Ω fonts
It sticks up.Selecting which kind of angle and how adjusting those skilled in the art can determine according to actual demand.
Although the present invention is disclosed as above with preferred embodiment, it is not limited to the present invention, any to be familiar with this
The people of technology can do various changes and modification, therefore the protection of the present invention without departing from the spirit and scope of the present invention
Range should be subject to what claims were defined.
