Abstract

The utility model discloses a drawing and drafting device of a breaker-drawing frame, which comprises a drafting roller and a forming trumpet positioned on the upstream of the drafting roller. The forming trumpet is provided with a flat trumpet hole, the small end of the trumpet hole is provided with the width and the length which are adaptive to a card silver which is fed into in the stack-up way; because the card silvers can be bundled into a flat shape and fed into in the vertical stack-up way, the contact area between the card silvers can be increased, accordingly, the mutual mixing is evener, the purpose that one drawing working procedure is omitted is attained compared with the traditional mixed drawing process, the production cost is reduced, the labor intensity of the staff is lightened, and the production efficiency is improved.

Description

The drafting drafting system of first drawing frame

Technical field

The utility model relates to the drawing frame technical field, relates in particular to a kind of drafting drafting system of first drawing frame.

Background technology

At present in the cotton spinning, blending employing bar wide in variety mixes method, that is: 6～8 one threads are arranged in parallel feeding drafting drafting system, this feeding mode has only strip edge fiber can obtain to a certain degree mutual mixing, and mixed effect is poor, for reaching well-mixed purpose, must use three road mixing in doubling step to mix at least, so both strengthen worker's labour intensity, increased production cost again, and influenced production efficiency.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of drafting drafting system of first drawing frame, have only strip edge mixed with fibers effective with solution, and the mixed with fibers weak effect of other position of strip, mixed processes is many, efficient is low, cost high technical problem.

For solving the problems of the technologies described above, the technical solution of the utility model is: the drafting drafting system of first drawing frame, comprise drawing rollers, be positioned at the head of the trumpet of described drawing rollers upstream, described head of the trumpet has the bellmouth orifice of flat, and the small end of described bellmouth orifice has and suitable width and the length of the carded sliver that feeds with overlapped way.

As a kind of improvement, described head of the trumpet has the bellmouth orifice of oval taper.

As further improvement, the small end of described bellmouth orifice have with two rows, about the suitable width and the length of the carded sliver that feeds of modes of three row.

As further improvement, the small end of described bellmouth orifice have with three rows up and down, about suitable width and the length of the carded sliver that feeds of the modes of two row.

Adopted technique scheme, the beneficial effects of the utility model are: the drafting drafting system of first drawing frame, comprise drawing rollers, be positioned at the head of the trumpet of described drawing rollers upstream, described head of the trumpet has the bellmouth orifice of flat, and the small end of described bellmouth orifice has and suitable width and the length of the carded sliver that feeds with overlapped way; Owing to carded sliver boundling can be become the feeding of flat stacked on top of one another, can increase contact area to each other, thereby make mutual mixing more even, can reach the purpose of economizing one mixing in doubling step than the mixed also technology of tradition, reduced production cost, alleviate worker's labour intensity, improved production efficiency.

Description of drawings

Fig. 1 is the working state schematic representation of the utility model embodiment;

Fig. 2 is the utility model embodiment flat head of the trumpet structural representation.

The specific embodiment

As shown in Figure 1 and Figure 2, the drafting drafting system of first drawing frame comprises drawing rollers 2, is positioned at the head of the trumpet 1 of described drawing rollers 2 upstreams, described head of the trumpet 1 has the bellmouth orifice of flat, and the small end of described bellmouth orifice has and suitable width and the length of the carded sliver that feeds with overlapped way.

Described head of the trumpet 1 has the bellmouth orifice of oval taper.

The small end of described bellmouth orifice have with two rows, about the suitable width and the length of the carded sliver that feeds of modes 3 of three row.

The small end of described bellmouth orifice have with three rows up and down, about suitable width and the length of the carded sliver that feeds of the modes of two row 3.

Owing to adopted the carded sliver 3 boundlings are become the feeding of flat stacked on top of one another, can increase contact area to each other, thereby make mutual mixing more even, can reach the purpose of economizing one mixing in doubling step than the mixed also technology of tradition, reduced production cost, alleviate worker's labour intensity, improved production efficiency.
