Study carefully the concern of personnel.
At present, the method that integrated composite spinning uses is mainly air-flowing type integrated composite spinning, such as patent CN104131371A is disclosed
A kind of collecting-spinning device, including drafting system and the apparatus for collecting that is arranged on before drafting system, drafting system at least wrap
A front roller and the front leather roller tangent with front roller are included, apparatus for collecting includes twisting resistance roller, resistance twist roller, negative-pressure air-suction abnormity
Pipe, air-flow prerotation vane and open-work cushion rubber, twisting resistance roller are arranged on before front roller, and negative-pressure air-suction special pipe is arranged on front roller
Between twisting resistance roller, open-work cushion rubber is set on twisting resistance roller and resistance twist roller is pressed on open-work cushion rubber, negative-pressure air-suction abnormity
It to be close on the upside of pipe on open-work cushion rubber, air-flow prerotation vane is arranged between front leather roller and resistance twist roller, though above-mentioned collecting-spinning device
It is so simple in construction, need not change spinning frame, but carry out needing the higher negative-pressure air-flow of pressure during air-flow boundling, just can guarantee that final
The quality of the integrated composite yarn of formation, the energy consumption for carrying out integrated composite spinning are higher.
In order to further reduce energy consumption, the cost of integrated composite spinning is reduced, researcher has carried out substantial amounts of research, but studies
Improvement of the personnel for apparatus for collecting is concentrated mainly on the shape for changing and gathering groove, such as patent CN104975385 discloses one
Kind improves the device of the integrated composite spinning of air-breathing slot structure form, and air-breathing groove slotted eye axis direction is improved into centre has interruption
Subsection setup, it is more reasonable that it can configure the negative pressure flow of whole agglomeration, while improves the air-breathing slot structure tool of setting
There is the self-cleaning function to grid ring, although above-mentioned collecting-spinning device saves the gas for carrying out integrated composite spinning to a certain extent
Stream consumption, improves the spinning effect of compact spinning, but carries out still needing the higher negative-pressure air-flow of pressure during integrated composite spinning, above-mentioned
Improve and do not solve the shortcomings that compact spinning power consumption is high inherently.
Therefore, study a kind of pressure of negative-pressure air-flow when can effectively reduce integrated composite spinning and ensure final obtained gather
The integrated composite spinning method tool of the quality of yarn is of great significance.
The content of the invention
The invention aims to overcome above-mentioned deficiency of the prior art, by installing guiding device in Nesting Zone,
So as to provide it is a kind of can effectively reduce integrated composite spinning when negative-pressure air-flow pressure and ensure the product of final obtained integrated composite yarn
The integrated composite spinning method of matter.
In order to achieve the above object, the technical solution adopted by the present invention is：
A kind of integrated composite spinning method, the overhung of grid ring is fixed with guiding device, the Nesting Zone in Nesting Zone
Jaw is exported between twist triangle zone positioned at spinning ring front roller is gathered, and Nesting Zone is mainly by grid ring and air draught flute
Pipe form, the air draught flute pipe upper end, which is provided with, gathers groove, and grid ring, which is covered in, gathers groove top, the bottom surface of the guiding device with
