Abstract
The invention discloses a buncher of a drawing frame. The buncher of the drawing frame comprises a buncher body which is provided with a buncher inlet, a buncher outlet and a buncher drawing port, wherein the buncher outlet is oval; the buncher drawing port is circularly arc; and the shoulder part of the buncher is an arc curved surface. With the adoption of the buncher of the drawing frame, a web is softly drawn by the buncher, the resistance of the buncher to the web is greatly reduced, fibers can pass through the buncher smoothly, phenomena of cotton fiber accumulation and return are reduced, and yarn evenness CV and 100 km yarn defect level are greatly improved.
Description
Technical field
The present invention relates to a kind of drawing frame buncher, belong to textile workpiece technical field.
Background technology
Drawing frame is when operation, loose and the web that advances at utmost speed is due to effect of inertia, be difficult to enter smoothly in the vertical horn mouth of placing of people, especially when front roller rotating speed is brought up to more than 1200 revs/min, most of web is broken through horn mouth upper end and separated with parent, add the impact of front inlet scoop wind-force, this situation more worsens.For overcoming this kind of phenomenon, between the outlet of drawing frame front roller and horn mouth, installed buncher and calender roller additional, so just can reduce the dissipation of fiber, make the strip of production tightr, also increased the capacity of bar cylinder.But, in process of production, while particularly producing products such as sky silk, Modal of regenerated celulose fibre, front inlet scoop air quantity ambassador fiber easily after condensers along being sucked away, cause slice; The position, forward position of air quantity hour buncher is amassed flower, is returned and spend seriously, and front upper roller is inhaled and spent seriously, very easily brings in sliver, causes yarn defect.Fig. 1, Figure 2 shows that the drawing frame buncher of prior art: place is less due to import and export, exit and import department approach right angle, therefore, output web acutely draws in through buncher, it is thicker that web becomes, correspondingly the resistance between buncher and fiber increases, and part fiber can not pass through buncher smoothly, causes buncher forward position to return flower.
Summary of the invention
Technical problem to be solved by this invention is the defect existing for prior art, and a kind of long-pending colored buncher of spending, return that reduces is provided.
For solving this technical problem, the invention provides a kind of drawing frame buncher, comprise buncher body, described buncher body is provided with buncher import, buncher outlet and buncher and draws mouth in, described buncher outlet is for oval, buncher draws mouthful place in for circular arc, and buncher shoulder is arc-shaped curved surface.
The size internal diameter of described buncher import is that narrow place is 25mm, and wide place is 28mm.
The size internal diameter of described buncher outlet is 15mm～13mm.
The internal diameter that described buncher draws mouth in is 15mm-20mm.
Described buncher body is to be made by iron casting.
Beneficial effect: buncher of the present invention relaxes web when buncher draws in, buncher reduces greatly to the resistance of web, fiber can successfully pass through from buncher, amasss flower and returns colored phenomenon and reduce, and the dry CV of Yarn and 10 myriametre yarn defect levels have larger improvement.
Accompanying drawing explanation
Fig. 1 is the structural representation front view of prior art drawing frame buncher;
Fig. 2 is the structural representation top view of prior art drawing frame buncher;
Fig. 3 is structural representation front view of the present invention;
Fig. 4 is structural representation top view of the present invention;
In figure: 1 buncher import, 2 buncher outlets, 3 bunchers draw mouth, 4 buncher shoulders in.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is specifically described.
Figure 3 shows that structural representation front view of the present invention.
Figure 4 shows that structural representation top view of the present invention.
The present invention includes buncher body, described buncher body is provided with buncher import 1, buncher outlet 2 and buncher and draws mouth 3 in.
The size internal diameter of described buncher import 1 is that narrow place is 25mm, and wide place is 28mm.
Described buncher outlet 2 is oval, and its size internal diameter is 15mm～13mm.
It is circular arc that described buncher draws mouthful 3 places in, its internal diameter is 15mm-20mm, and circular arc causes its angle and strengthens, and web is relaxed than before when buncher draws in, buncher reduces greatly to the resistance of web, and fiber can successfully pass through from buncher.
Buncher shoulder 4 is arc-shaped curved surface, and will export trailing edge lengthening, contact-making surface and pressure between buncher and roller are increased, effectively controlled the power of fiberoptic fiber, avoided front inlet scoop because of the air quantity ambassador fiber problem that easily edge is sucked away after condensers.
Described buncher body is to be made by iron casting.
Buncher of the present invention relaxes web when buncher draws in, and buncher reduces greatly to the resistance of web, and fiber can successfully pass through from buncher, amasss flower and returns colored phenomenon and reduce, and the dry CV of Yarn and 10 myriametre yarn defect levels have larger improvement.
The above-mentioned embodiment of the present invention, just illustrates, and is not only, and change within the scope of the present invention all or that be equal in scope of the present invention is all surrounded by the present invention.
