Abstract
The invention relates to a comforspin negative pressure airflow guiding method for compact spun yarn. An airflow shield plate is arranged inside a fiber gathering region formed by a front roller, a damping roller and a mesh roller. Dense air inlets are formed in a top plate of the airflow shield plate. The bottom of a left side plate and the bottom of a right side plate of the airflow shield plate are attached to the arc surface of the mesh roller, so that a negative pressure bin is formed by the left and right side plates and the top plate of the airflow shield plate and the mesh roller; when a negative pressure suction piece and a negative pressure air source are communicated, air outside the airflow shield plate enters the negative pressure bin through the multiple air inlets in the top plate and flows towards a skew notch of the negative pressure suction piece through meshes of the mesh roller, so that the negative pressure enables fiber bundle yarn hairness to converge inside the negative pressure bin, and drafted fiber bundles enter the negative pressure bin and flow towards the skew notch along with the negative pressure airflow; when the fiber bundles pass through the fiber gathering region, the fiber bundles are attached to the surface of the mesh roller and gathered along the edge of the skew notch. The comforspin negative pressure airflow guiding method has the advantages that the structure is simple and energy consumption can be lowered.
Description
Technical field
The present invention relates to a kind of card to rub the negative-pressure air-flow guidance method spun for gathered yarn, belong to the negative-pressure air-flow centralizing technique field of compact spinning machine.
Background technology
Ring ingot negative pressure type compact spinning fine spining machine, for reducing spinning triangular zone, adds the negative-pressure air-flow apparatus for collecting that fibre bundle gathers in dominant draft downstream.Under negative-pressure air-flow effect, fibre bundle, along with while mesh roller rotational conveyance, is gathered at mesh surface of roller at the medium position of air draught notch, thus is effectively reduced spinning triangular zone, reaches the object reducing ribbon filoplume and increase ribbon tension force.
Disclosed card rubs and spins formula negative-pressure air-flow aggregation method at present, be provided with front roller roller and damping roller formation fiber aggregate district at mesh roller outer surface, be provided with one in mesh roller and there is the negative-pressure air-suction part communicated with negative pressure source of the gas, negative-pressure air-suction part is provided with air draught notch, a negative-pressure air-flow guider is set gathering region place, outside air enters mesh roller from the both sides of guider, and the negative pressure aspiration wind part arranged by its inner chamber and discharging, fibre bundle can be gathered at the middle part of air draught notch.
Above-mentioned fibre bundle is in agglomeration, the air that outside sucks enters mesh surface of roller from the both sides of air guider, being introduced into mesh roller along mesh roller again gathers in region, section, and fibre bundle is pressed into a ribbon closely by sucking air to be formed along the larger axial force of mesh surface of roller gathering in region.Therefore in agglomeration, need larger negative-pressure air-flow, the air of suction just can be made to form very large axial air quantity and be pressed in effect fibre bundle reaching and gathers.But when in fact fibre bundle is by gathering region, gather distance relatively short, and when the axial air quantity of both sides is pressed on fibre bundle, make the contrary air-flow in part direction occur mutual interference phenomenon, so cause the loss of negative-pressure air-flow, therefore fibre bundle required energy consumption when gathering is relatively high.
Summary of the invention
The object of the invention is a kind of simple, that energy consumption can be reduced card of structure that provides to rub the negative-pressure air-flow guidance method spun for gathered yarn.
The present invention is the technical scheme achieved the above object: a kind of card rubs the negative-pressure air-flow guidance method spun for gathered yarn, front roller roller and damping roller are arranged on the periphery of mesh roller, be provided with one in mesh roller and there is the negative-pressure air-suction part communicated with negative pressure source of the gas, negative-pressure air-suction part is provided with a skew notch relative with mesh surface of roller, it is characterized in that: in the fiber aggregate district that front roller roller and damping roller and mesh roller are formed, be provided with an air-flow cover plate, the top board of air-flow cover plate is provided with more than four rows along line direction before fibre bundle, often row is provided with more than three apertures at the intensive air admission hole of 0.5-1.0mm, the width w1 in the air admission hole region on top board is equal to or greater than the width w2 with the mesh area on mesh roller, the left side plate of air-flow cover plate is fitted in the curved surfaces of mesh roller bottom it, air-flow cover plate left side plate and top board and mesh roller is made to form a negative pressure cabin, when negative-pressure air-suction part communicates with negative pressure source of the gas, the air of air-flow cover plate outside enters in negative pressure cabin by the multiple air admission holes on top board, and the skew notch of negative-pressure air-suction part is flowed to by the mesh of mesh roller, make negative-pressure air-flow in negative pressure cabin, form an air-flow that fibre bundle filoplume is restrained, fibre bundle after drawing-off enters negative pressure cabin, skew notch is flowed to negative-pressure air-flow, fibre bundle is through fiber aggregate region, fibre bundle is attached to mesh surface of roller and edge along skew notch gathers.
The present invention is provided with intensive air admission hole at air-flow cover plate along on line direction before fibre bundle, the bottom of air-flow cover plate left side plate is fitted in the curved surfaces of mesh roller, make air-flow cover plate left side plate and top board can form a negative pressure cabin with mesh roller, make negative-pressure air-flow can form an air-flow that fibre bundle filoplume is restrained in negative pressure cabin, when entering in negative pressure cabin by air admission hole each on air-flow cover plate under the negative-pressure air-flow effect of extraneous air in negative-pressure air-suction part, the interference of extraneous air to fibre bundle can be reduced by air-flow cover plate, make the air draught of suction in negative pressure cabin form a stable negative-pressure air-flow simultaneously, for fibre bundle, the edge along skew notch gathers at mesh surface of roller, because the air draught in negative pressure cabin can not disturb mutually, therefore must restraint through fiber aggregate region at fiber, fibre bundle can reliably be gathered along the edge of mesh surface of roller at skew notch, after making drawing-off, fibre bundle can reach compacting effect.The present invention is few due to windage loss, therefore without the need to larger negative-pressure air-flow, just can reach the effect that fibre bundle gathers, and structure is simple, and can reduce energy consumption.
