Abstract
The invention relates to a spinning eddy current spraying nozzle, which belongs to a component of spinning machinery. When in use, an air spraying eddy current spinning device of the existing spinning eddy current spraying nozzle has the defect that remained fiber can easily cause the blockage of an inner cavity of the eddy current spraying nozzle. The spinning eddy current spraying nozzle of the invention is provided with a hollow pipe body, the upper end of the pipe body is provided with an air flow spraying hole communicated with the inner cavity, an eddy current chamber is formed in the inner cavity at an outlet of the air flow spraying hole, and the lower end of the pipe body is provided with an air flow spraying passage. Through the additional arrangement of the air flow passage for spraying the air flow, the invention prevents the remained fiber from blocking the inner cavity of the eddy current spraying nozzle, and improves the yarn thread efficiency and the spinning quality.
Description
Technical field
The invention belongs to textile machinery component, especially relevant with a kind of spinning eddy current spraying nozzle.
Background technology
Air injection air vortex spinning is a kind of novel spinning technology, the existing spinning apparatus that is used for air injection air vortex spinning comprises hollow eddy current spraying nozzle, spindle shape doffing tube, negative pressure cavity and gas channel, the eddy current spraying nozzle tube wall is provided with the air flow jetting hole that is communicated with hollow cavity, the inner chamber at air flow jetting hole exits place forms the minor air cell, the import of air flow jetting hole links to each other with gas channel, doffing tube inserts from eddy current spraying nozzle inner chamber lower end, the yarn mouthpiece that draws of doffing tube is connected to the minor air cell, doffing tube outer wall and eddy current spraying nozzle internal chamber wall have the gap, and eddy current spraying nozzle inner chamber lower end is communicated with negative pressure cavity.During spinning, sliver or rove are exported the parallel fibers bundle behind drafting system, and fibre bundle enters the minor air cell through the fiber input channel of eddy current spraying nozzle porch.Jet-stream wind forms rotating vortex from the ejection of air flow jetting hole high speed in the minor air cell.The front end of part fiber enters doffing tube in the fibre bundle, and tail end is separated the formation free end owing to be subjected to the effect of rotating vortex from fibre bundle, and lodging is on the doffing tube conical surface, rotation with eddy current is rotated, thereby twisting is coated on the yarn that is forming, and the fiber of not separating from fibre bundle then becomes parallel shape to be formed yarn core by looping in the middle of yarn.When in the spinning process or spinning broken end back starts, having fiber unavoidably residues in the minor air cell and influences spinning quality and spinning efficiency, usually connect negative pressure cavity at the eddy current spraying nozzle tail end, by suction function with residue siphon away reach the cleaning minor air cell, but, cause residual fiber by vacuum suction the time, to be jammed in easily in the gap between doffing tube and the eddy current spraying nozzle internal chamber wall because the gap can not be excessive between doffing tube and the eddy current spraying nozzle internal chamber wall.
Summary of the invention
Purpose of the present invention is exactly to solve the defective that residual fiber that the air injection air vortex spinning apparatus that uses above-mentioned spinning eddy current spraying nozzle exists causes the eddy current spraying nozzle inner chamber to stop up easily, provides a kind of and can effectively eliminate the spinning eddy current spraying nozzle that inner chamber stops up.For this reason, the present invention is by the following technical solutions:
A kind of spinning eddy current spraying nozzle, it has hollow tube body, and the body upper end is provided with the air flow jetting hole that is communicated with its inner chamber, and the inner chamber at air flow jetting hole exits place forms the minor air cell, and it is characterized in that: described body lower end is provided with the air flow jetting passage.
When the present invention uses, the eddy current spraying nozzle upper end is undertaken in drafting system, air flow jetting hole and air-flow injection channel are communicated with high-pressure air source by gas channel, the eddy current spraying nozzle lower end is communicated with the impurities removal negative pressure cavity, the impurities removal negative pressure cavity is connected with negative pressure source of the gas and fiber collecting device, doffing tube is from inserting from eddy current spraying nozzle inner chamber lower end, and the yarn mouthpiece that draws of doffing tube is connected to the minor air cell, and doffing tube outer wall and eddy current spraying nozzle internal chamber wall have the gap.Sliver or rove are exported the parallel fibers bundle behind drafting system, fibre bundle enters the minor air cell through the fiber input channel of eddy current spraying nozzle porch.Jet-stream wind forms rotating vortex in the minor air cell and realizes spinning from the ejection of primary air spray-hole high speed.The residual negative pressure by negative pressure cavity of fiber that does not form yarn is drawn into negative pressure cavity, outputs to fiber collecting device.Air-flow is from air flow jetting passage ejection also formation swirling eddy, make that fiber is residual to be in the motion all the time, and the gap between doffing tube outer wall and eddy current spraying nozzle internal chamber wall also forms negative pressure, can be with the residual negative pressure cavity that is attracted into smoothly of fiber, prevent from that fiber is residual to be jammed in the gap.
As to technique scheme replenish and perfect, the present invention also comprises following technical characterictic:
Described air flow jetting passage is the hole, and it is communicated with described inner chamber.
Described air flow jetting passage can also be for being arranged at the groove of outer surface of tube body, and groove runs through the body lower surface.
Use the present invention can reach following beneficial effect: by on eddy current spraying nozzle, setting up air flow jetting channel injection air-flow, to prevent from that fiber is residual to be jammed in the eddy current spraying nozzle, improved yarn efficient, also improved the spinning quality simultaneously.
