Description
Technical field
Block the negative-pressure air-flow guidance method for rubbing and spinning for gathered yarn the present invention relates to a kind of, belong to the negative of compact spinning machine
Pressure gas stream centralizing technique field.
Background technology
Ring ingot negative pressure type compact spinning spinning frame increased what fibre bundle gathered to reduce spinning triangular zone in dominant draft downstream
Negative-pressure air-flow apparatus for collecting.Under negative-pressure air-flow effect, while fibre bundle is with mesh roller rotational conveyance, in air draught notch
Medium position gathered in mesh surface of roller, so as to effectively reduce spinning triangular zone, reach reduction ribbon filoplume and
Increase the purpose of ribbon tension force.
Presently disclosed card rubs spinning formula negative-pressure air-flow aggregation method, be mesh roller outer surface be provided with front roller roller and
Damping roller forms fiber aggregate area, and one is provided with mesh roller has the negative-pressure air-suction part communicated with negative pressure source of the gas, bears
Pressure air draught part is provided with air draught notch, and gathering at region one negative-pressure air-flow guider of setting, outside air is from guider
Both sides enter at mesh roller, and discharged by the negative pressure aspiration wind part that its inner chamber is set, enable fibre bundle in air draught groove
Gathered at the middle part of mouth.
In agglomeration, the air of outside suction enters mesh roller table to above-mentioned fibre bundle from the both sides of air director
Face, then be introduced into mesh roller and gather in the region of section along mesh roller, fibre bundle is gathering in region by sucking air
To be formed a close ribbon is pressed into along the larger axial force of mesh surface of roller.Therefore in agglomeration, it is necessary to
Larger negative-pressure air-flow, can just enable the air of suction form very big axial air quantity and be pressed on fibre bundle the effect for reaching and gathering
Really.But actually fibre bundle is by gathering during region, gather that distance is relatively short, and the axial air quantity of both sides is pressed on fibre bundle
When so that part air-flow in opposite direction occurs interfering phenomenon, so cause the loss of negative-pressure air-flow, therefore fibre bundle to exist
Required energy consumption is of a relatively high when gathering.
The content of the invention
The purpose of the present invention is that a kind of simple structure, the card of energy reducing energy consumption of providing rubs spinning for the negative pressure gas of gathered yarn
Stream guidance method.
The present invention is that the technical scheme for reaching above-mentioned purpose is：It is a kind of to block the negative-pressure air-flow guiding rubbed and spin for gathered yarn
Method, front roller roller and damping roller are arranged on the periphery of mesh roller, and one is provided with mesh roller has and negative pressure
The negative-pressure air-suction part that source of the gas is communicated, negative-pressure air-suction part is provided with relative with a mesh surface of roller skew notch, and it is special
Levy and be：An air-flow cover plate, gas are provided with the fiber aggregate area that front roller roller and damping roller are formed with mesh roller
The top board for flowing cover plate is provided with more than four rows along line direction before fibre bundle, often row to be provided with more than three apertures intensive in 0.5-1.0mm
Air admission hole, the width w1 of the air inlet bore region on top board is equal to or more than the width w2 with the mesh area on mesh roller,
Its bottom of the left side plate of air-flow cover plate is fitted in the curved surfaces of mesh roller, makes air-flow cover plate left side plate and top board and net
Hole roller forms a negative pressure cabin, and when negative-pressure air-suction part is communicated with negative pressure source of the gas, the air outside air-flow cover plate passes through top board
On multiple air admission holes enter in negative pressure cabin, and the skew notch of negative-pressure air-suction part is flowed to by the mesh of mesh roller, make negative pressure
Air-flow forms one in negative pressure cabin makes the convergent air-flow of fibre bundle filoplume, and the fibre bundle after drawing-off enters negative pressure cabin, with negative pressure
Air flow direction skew notch, when fibre bundle is by fiber aggregate region, fibre bundle is attached to mesh surface of roller and along the side of skew notch
Gather at edge.
The present invention is provided with intensive air admission hole before air-flow cover plate is along fibre bundle on line direction, air-flow cover plate left side plate
Bottom is fitted in the curved surfaces of mesh roller, air-flow cover plate left side plate and top board is formed a negative pressure with mesh roller
Storehouse, making negative-pressure air-flow that one can be formed in negative pressure cabin makes the convergent air-flow of fibre bundle filoplume, when extraneous air is in negative-pressure air-suction
Entered in negative pressure cabin by each air admission hole on air-flow cover plate under negative-pressure air-flow effect in part, outside can be reduced by air-flow cover plate
Interference of the air to fibre bundle, while air draught of the suction in negative pressure cabin is formed a negative-pressure air-flow for stabilization, for fibre
Dimension beam gathers along the edge of skew notch in mesh surface of roller, because the air draught in negative pressure cabin will not be interfered, because
This enables fibre bundle reliably along mesh surface of roller in the edge of skew notch when fiber palpus beam is by fiber aggregate region
Gather, fibre bundle reaches compacting effect after enabling drawing-off.The present invention is few due to windage loss, therefore without larger negative-pressure air-flow,
The effect that fibre bundle gathers, simple structure, and energy reducing energy consumption can just be reached.
