Description
Technical field
This utility model belongs to technical field of textile machine, especially relevant with a kind of yarn pulling device.
Background technology
In existing Rotor Spinning Technology field, enterprise, in order to reduce production cost, shortens technical process as far as possible, saves
Roving Frames, the method using super draft spinning, but the device of existing common super draft spinning is increasing spun yarn
After drafting multiple, proparea sliver spreads, and compactness declines, and causes limit fiber to increase, and resultant yarn filoplume increases, then through winder yarn
Line filoplume is multiplied again, affects later process, can increase technique on the contrary.
Utility model content
The purpose of this utility model is intended to overcome existing drawbacks described above, it is provided that it is special that a kind of yarn formation structure reaches bifilar structure
Levying, yarn texture is tight, the yarn pulling device that filoplume is few.
To this end, this utility model is by the following technical solutions: a kind of yarn pulling device, it is characterized in that, described drawing-off
Mechanism includes front draft assembly, intermediate draft assembly and the first break draft assembly set gradually, front draft assembly include front leather roller and
Front roller, front roller is positioned at below described front leather roller, is front draft zone between front roller and front leather roller, described first break draft assembly
Including rear roller and rear roller, rear roller is positioned at below described rear roller, for first break draft district between rear roller and rear roller, described
Intermediate draft assembly include lower support structure and upper pressure structure, lower support structure include keeping at a certain distance away arrange two with
Step belt wheel and connect the Timing Belt of suit two synchronous pulleys, upper pressure structure include two driven press rolls, drivewheel with
And the pressurization transmission band being connected on two driven press rolls and drivewheel outer circumference surface, drivewheel is arranged at described two and driven adds
The top of pinch roller, a section between two driven press rolls of transmission band that pressurizes is parallel with Timing Belt, between two driven press rolls
Distance less than the distance between two synchronous pulleys, and two driven press rolls are respectively positioned between two synchronous pulleys, and pressurization passes
It is intermediate draft district between dynamic band and the upper strata of Timing Belt.
During use, two parallel strip parallel feeding front draft zones, enter intermediate draft district, subsequently into first break draft
District, is finally gripped output, two one thread keeping parallelism released states by rear roller and rear roller, exports a fixed length from first break draft district
Remerge after degree, and be formed with the yarn of bifilar architectural feature by the twisting of same spindle.
This utility model can reach following beneficial effect: by using the two parallel Detaching drafts of one thread to be finally merged into
Row twisting, increases the drawing-off degree of yarn significantly, makes yarn texture tight, and anti-fluffing and anti-pilling is good, by by Timing Belt and pressurization
The intermediate draft district drawing-off of transmission band composition, the gripping to yarn is reliable, and yarn uniform force makes yam surface fiber alignment whole
Together, filoplume is few, improves yarn qualities.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.
As it is shown in figure 1, this utility model includes front draft assembly, intermediate draft assembly and the first break draft group set gradually
Part, front draft assembly includes front leather roller 5 and front roller 7, and front roller 7 is positioned at below described front leather roller 5 and leans, front roller 5
And be front draft zone between front leather roller 7, described first break draft assembly includes rear roller 1 and rear roller 2, and rear roller 2 is positioned at described
Below rear roller 1 and lean, for first break draft district between rear roller 2 and rear roller 1, described intermediate draft assembly includes lower
Bearing structure and upper pressure structure, lower support structure includes keeping at a certain distance away two synchronous pulleys 8 arranged and connects suit two same
Step belt wheel 8 Timing Belt 9, upper pressure structure include 10, drivewheel 4 of two driven press rolls and be connected to two driven
Pressurization transmission band 3 on press roll 10 and drivewheel outer circumference surface, drivewheel 4 is arranged at the upper of described two driven press rolls 10
Side, a section between two driven press rolls 10 of transmission band 3 that pressurizes is parallel with Timing Belt 9, between two driven press rolls 10
Distance is less than the distance between two synchronous pulleys 8, and two driven press rolls 10 are respectively positioned between two synchronous pulleys 8, pressurization
It it is intermediate draft district between the upper strata of transmission band 3 and Timing Belt 9.
During use, two parallel strip 6 parallel feeding front draft zones, enter intermediate draft district, subsequently into first break draft
District, is finally gripped output, two one thread keeping parallelism released states by rear roller and rear roller, exports a fixed length from first break draft district
Remerge after degree, and be formed with the yarn of bifilar architectural feature by the twisting of same spindle.
