Description
Technical field
The utility model is related to a kind of big cornerite for spinning and grips 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, when especially in larger distance, spinning tow, due to discontinuity, is easy to tow occur to exist in drafting process
Drafting multiple is too small between drafting machine, the problem of tensile strength is relatively low.Therefore, often protected in the prior art by means of nip roiler
Drafting multiple is demonstrate,proved, but nip roiler of the prior art mostly increases traction times by the way of two nip roiler composition nip roilers pair
Number, but the cornerite of this mode nip roiler is often smaller, exists and grips the limited defect of drafting force, for long range stretching often
Enough draw ratios can not be increased.Meanwhile, the quantity of required nip roiler often can just realize that gripping is led more than 5
Stretch function.Because nip roiler number is more, friction area can be increased, cause lousiness rate to raise.Cause precursor quality degradation,
Product disqualification rate is very high.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of gripping roller group of big cornerite, the technology taken
Side is as follows：
The purpose of this utility model is that providing a kind of big cornerite for spinning grips drawing-off roller group, and the big cornerite is gripped
The first axially in parallel nip roiler 2 that rod group is connected by gear-box 1 and by driving shaft with gear-box 1, the second nip roiler 3 and
Three nip roilers 4 are constituted, wherein, the first nip roiler 2, the second nip roiler 3 and the 3rd nip roiler 4 are distributed in isosceles triangle, and first grips
Roller 2 is located at top, and the second nip roiler 3 and the 3rd nip roiler 4 are located at bottom, and spinning is from the second nip roiler 3 or the bottom of the 3rd nip roiler 4
Portion is laid out into after bypassing the first nip roiler 2 through Ω shape routes by the 3rd nip roiler 4 or the bottom of the second nip roiler 3, wherein, spinning
Cornerite through the first nip roiler 2 is not less than 240 degree.
Preferably, second nip roiler 3 is identical with the diameter of the 3rd nip roiler 4.
Preferably, second nip roiler 3, the 3rd 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 the 3rd nip roiler 4.
Preferably, second nip roiler 3 and plane where the axis of the 3rd nip roiler 4 are parallel to the ground.
Preferably, first nip roiler 2, the second nip roiler 3 are identical with the length and diameter of the 3rd nip roiler 4.
It is highly preferred that the length of first nip roiler 2 is 1200-1600mm, a diameter of 300-350mm.
The beneficial effect that the utility model is obtained：
The cornerite that big cornerite provided by the utility model grips roller group is big, and bigger curable grip is provided for spinning tow,
There is drawing-off function simultaneously, the draw ratio and tensile strength between nip roiler and solvent stretching-machine can be effectively improved.
The quantity provided by the utility model for gripping the gripping draw roll that roller group is used is few, it is only necessary to three nip roilers
Realize drawing-off function.Generally require that using more than five nip roilers effective drawing-off function could be realized in the prior art.
Brief description of the drawings
Fig. 1 is the positive structure diagram of the present utility model for gripping roller group.
Fig. 2 is the overlooking the structure diagram that the utility model grips roller group.
In figure：1, gear-box；2, the first nip roiler；3, the second nip roiler；4, the 3rd nip roiler.
Embodiment
The utility model is described in further details below in conjunction with the accompanying drawings, but described further below is not intended as to this practicality
New restriction.
Fig. 1 be a kind of preferred scheme of the utility model in gripping roller group positive structure diagram.Fig. 2 is that this practicality is new
Type grips the overlooking the structure diagram of roller group.It was found from Fig. 1 and Fig. 2, the big cornerite grips roller group mainly by a gear-box 1
Constituted with three nip roilers being connected by power transmission shaft with gear-box 1.Three nip roilers are located at the same side of gear-box 1, and axle
To it is parallel and in isosceles triangle distribution.Superposed is the first nip roiler 2, and what it is positioned at bottom is that the second nip roiler 3 and the 3rd is held
Hold roller 4.Wherein, diameter, the second nip roiler 3 of the first gripping rod 2 are identical with the diameter of the 3rd nip roiler 4, all nip roilers
Length is identical, and length is 1500mm, a diameter of 350mm of the first nip roiler 2, the second nip roiler 3 and the 3rd nip roiler 4.
In spinning production process, during spinning tow enters gripping roller group from the bottom of the 3rd nip roiler 4, by Ω fonts
Route is bypassed after the first nip roiler 2, is drawn by the bottom of the second nip roiler 3 and is gripped roller group.Wherein, spinning is gripped by first
The cornerite of roller 2 is 240 degree, and cornerite when by the second nip roiler 3 and three nip roilers 4 is all higher than 200 degree.For cornerite angle
Degree, can by set each grip rod diameter and position, and tow turnover when angle be adjusted.To make second to hold
The cornerite for holding the nip roiler 4 of roller 3 and the 3rd is bigger, can properly increase height during tow turnover, make on two bases of Ω fonts
Stick up.From which kind of angle and how to adjust those skilled in the art and can determine according to the actual requirements.
Although the utility model is disclosed as above with preferred embodiment, it is not limited to the utility model, appoints
What person skilled in the art, is not departing from spirit and scope of the present utility model, can do various changes and modification, therefore
What protection domain of the present utility model should be defined by claims is defined.
