Problems solved by technology

The application of the large forward-type flat-drawing pressure rod has overcome the above-mentioned technical problems very well, but after mass production practice by the enterprise, its disadvantages have gradually emerged, mainly in the following: 1. The frictional resistance is large when the strands wrap around the pressure rod, which affects The drafting efficiency of the strands; 2. Before the strands enter the middle jaw, there are many exposed fibers, which will affect the further whole bundle

Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the present invention will be further described:

[0011] Such as figure 1 , figure 2 As shown, the present invention is a pressure bar in the rear drafting area of ​​the front groove and rear wheel type spun yarn, which includes an upper pin combination 1, and the upper pins 2 of the upper pin combination 1 are alternately arranged with parallel lower pressure bars 3 and upper pressure bars 4 , the two ends of the upper pressure rod 4 are provided with snap rings 6, the upper pressure rod 4 inside the snap ring 6 is relatively provided with a groove wheel 5, and the lower pressure rod 3 is relatively provided with an annular groove 7.

[0012] The opening gap of the annular groove 7 is larger than the opening gap of the grooved wheel 5 .

[0013] The grooved wheel 5 and the upper pressure rod 4 are movable.

[0014] The technical advantage of the present invention is that without changing other structures of the exist...

Abstract

The invention discloses a fore-trench rear-wheel type spinning back-drafting-zone pressure bar which comprises a top-pin combination. A top pin of the top-pin combination is crisscross provided with a lower pressure bar body and an upper pressure bar body which are parallel to each other, each of two ends of the upper pressure bar body is provided with a snap ring, the upper pressure bar body inside the snap rings is oppositely provided with trench wheels, and the lower pressure bar body is oppositely provided with annular trenches. The fore-trench rear-wheel type spinning back-drafting-zone pressure bar is simple in structure, efficient and stable in operation, fiber strand drafting and bunching efficiency is improved, and meanwhile, spinning yarn quality is greatly improved.

Description

technical field [0001] The invention relates to textile equipment, in particular to a front groove and rear wheel type pressure bar in the rear drafting area of ​​spun yarn. technical background [0002] To achieve heavy weight, large draft and high-efficiency spinning, we must proceed from the process effect, and solve the problems exposed by the existing heavy weight, large draft process on the existing spinning frame in terms of drafting type, drafting component design, and reasonable selection of key equipment. The problem that came out; the pressure bar in the rear drafting area is one of the important components to realize the high-efficiency process, and it plays a vital role in the real realization of the process concept of "heavy weight of roving, large draft of spun yarn". The application of the large forward-type flat-drawing pressure rod has overcome the above-mentioned technical problems very well, but after the mass production practice of the enterprise, its di...
