Abstract
The utility model discloses a spinning vortex tube, belonging to spare parts of textile machinery. For solving the defects of easy blockage of the inner cavity of the vortex tube owing to residual fibers when using the air jet vortex spinning device of the prior spinning vortex tube, the spinning vortex tube of the utility model is provided with a hollow inner cavity, an air jet hole which is communicated with the inner cavity is arranged at the upper end of a tube body, the inner cavity at the exit of the air jet hole forms a vortex chamber, and an air jet channel is arranged at the lower end of the tube body. In the utility model, through adding the air jet channel for jetting the air, the fiber residues are prevented from blocking the inner cavity of the vortex tube, and the spinning efficiency and spinning quality are improved.
Description
Technical field
The utility model belongs to textile machinery component, and is especially relevant with a kind of spinning eddy current pipe.
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 vortex tube, spindle shape doffing tube, negative pressure cavity and gas channel, the vortex tube tube wall is provided with the air flow jetting hole that is communicated with the vortex tube inner chamber, the vortex tube 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 vortex tube inner chamber lower end, the yarn mouthpiece that draws of doffing tube is connected to the minor air cell, doffing tube outer wall and vortex tube internal chamber wall have the gap, and vortex tube 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 vortex tube 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 vortex tube 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 vortex tube internal chamber wall because the gap can not be excessive between doffing tube and the vortex tube internal chamber wall.
The utility model content
The purpose of this utility model is exactly to solve the defective that residual fiber that the air injection air vortex spinning apparatus that uses above-mentioned spinning eddy current pipe exists causes the vortex tube inner chamber to stop up easily, provides a kind of and can effectively eliminate the spinning eddy current pipe that the vortex tube inner chamber stops up.For this reason, the utility model is by the following technical solutions:
A kind of spinning eddy current pipe, it has hollow cavity, and the body upper end is provided with the air flow jetting hole that is communicated with 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 utility model uses, the vortex tube 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 vortex tube 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 vortex tube 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 vortex tube 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 vortex tube 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 vortex tube 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 utility model 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 utility model can reach following beneficial effect: by on vortex tube, setting up air flow jetting channel injection air-flow, to prevent from that fiber is residual to be jammed in the vortex tube, improved yarn efficient, also improved the spinning quality simultaneously.
