Description

A kind of airflow guiding device with arc inlet channel
Technical field
The utility model relates to new technical field of spinning, and particularly relates to a kind of airflow guiding device with arc inlet channel.
Background technology
Hollow roller type compact spinning is an important branch of air-negative-pressure formula compact spinning system, and it is because significantly reducing Yarn filoplume, improve yarn Performance and by the extensive concern of insider.Airflow guiding device is the element that hollow roller compact spinning system is exclusive, and air draught air system is drawn by it Enter Nesting Zone, improve compacting effect, improve air-flow utilization rate.Airflow guiding device can cover delivery roller jaw to the whole Nesting Zone of front roller nip Territory, yarn completes agglomeration in airflow guiding device, and airflow guiding device is optimized transformation, increases the stress in yarn motion process, Guide yarn specification to gather, improve the control action to yarn, improve yarn bar and do, spinning triangular zone can be reduced to a greater degree, thus enter one Step reduces harmful filoplume.
Summary of the invention
The purpose of this utility model is to provide a kind of airflow guiding device with arc inlet channel, by using one to have certain thickness air-flow Prerotation vane, and the upper deep-slotted chip breaker of equidistantly arrangement is had at the upper surface of prerotation vane, lower surface has the lower arcuate slot of equidistantly arrangement, upper deep-slotted chip breaker And between lower arcuate slot, using curved channel to connect so that negative pressure produced when upper deep-slotted chip breaker, curved channel and lower arcuate slot enter in Nesting Zone There is vortex flow clockwise or counterclockwise, then the fiber strip in Nesting Zone is produced weak twist and gather effect, rise while effect is gathered in generation Act on to weak twisting, improve yarn quality.
For achieving the above object, the utility model adopts the technical scheme that: a kind of airflow guiding device with arc inlet channel, including upwards Embedding and sell gentle stream prerotation vane, the described pin that upwards embeds is arcuate structure, upwards embeds pin including left arc and right arc upwards embeds pin, a described left side Arc upwards embeds pin and right arc upwards embeds pin and is separately fixed at the left and right sides above air-flow prerotation vane, in the left and right of the lower section of air-flow prerotation vane Both sides add left support pin and right support pin respectively, and described air-flow prerotation vane is cuboid structure, the leading flank of described air-flow prerotation vane, rear side Face, left surface, right flank, upper side and downside are arcwall face, and described upper side and downside are the arcwall face concaved, described air-flow The thickness of prerotation vane is between 4-6mm, and what the upper surface being positioned at Nesting Zone at described air-flow prerotation vane had an equidistantly arrangement has the structure that concaves Or inwardly male structure first on deep-slotted chip breaker, lower surface has first lower arcuate slot with concave structure or inside male structure of equidistantly arrangement, By having the first curved channel connection of concave structure or inside male structure between deep-slotted chip breaker and the first lower arcuate slot on described first, at described gas What stream prerotation vane was positioned at that the left surface of Nesting Zone has an equidistantly arrangement has deep-slotted chip breaker on the second of inside male structure or the structure that concaves, and right flank is opened There is second lower arcuate slot with inside male structure or the structure that concaves of equidistantly arrangement, logical between deep-slotted chip breaker and the second lower arcuate slot on described second Cross the second curved channel connection with inside male structure or the structure that concaves.
During use, first by left and right arc, airflow guiding device upwards being embedded pin and be fixed on cap bar, during spinning, airflow guiding device presses On hollow front roller, wherein left support pin contacts with front roller with right support pin, by hollow front roller produce negative pressure on first deep-slotted chip breaker, First curved channel and the first lower arcuate slot enter into Nesting Zone, and after on the second lower arcuate slot, the second curved channel and second deep-slotted chip breaker flow out, Then in Nesting Zone, produce the vortex flow having clockwise or counterclockwise, then the fiber strip in Nesting Zone is produced weak twist and gather effect, producing Life plays weak twisting effect while gathering effect, improves yarn quality.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of airflow guiding device with arc inlet channel, including upwards embedding pin gentle stream prerotation vane 1, upwards embed pin For arcuate structure, upwards embedding pin 2 including left arc and right arc upwards embeds pin 3, left arc upwards embeds pin 2 and right arc upwards embeds pin 3 are separately fixed at the left and right sides above air-flow prerotation vane 1, add left support pin 4 He respectively in the left and right sides of the lower section of air-flow prerotation vane 1 Right support pin 5, air-flow prerotation vane 1 is cuboid structure, the leading flank of air-flow prerotation vane 1, trailing flank, left surface, right flank, upper side Being arcwall face, upper side and downside with downside and be the arcwall face concaved, the thickness of air-flow prerotation vane 1 is between 4-6mm, at air-flow Prerotation vane 1 be positioned at the upper surface of Nesting Zone have equidistantly arrangement have concave structure or inwardly male structure first on deep-slotted chip breaker 6, following table Face has first lower arcuate slot 7 with concave structure or inside male structure of equidistantly arrangement, deep-slotted chip breaker 6 and the first lower arcuate slot 7 on first Between connect by having the first curved channel 8 of concave structure or inside male structure, the left surface being positioned at Nesting Zone at air-flow prerotation vane 1 has Equidistantly arrangement has deep-slotted chip breaker 9 on the second of inside male structure or the structure that concaves, and what right flank had an equidistantly arrangement has inside male structure Or the second lower arcuate slot 10 of the structure that concaves, by there is inside male structure or concaving between deep-slotted chip breaker 9 and the second lower arcuate slot 10 on second Second curved channel 11 of structure connects.
During use, first airflow guiding device is upwards embedded pin 2 by left arc and right arc upwards embeds pin 3 and is fixed on cap bar, spinning Time, airflow guiding device is pressed against on hollow front roller, and wherein left support pin 4 contacts with front roller with right support pin 5, is produced by hollow front roller Raw negative pressure deep-slotted chip breaker the 6, first curved channel 8 and first lower arcuate slot 7 on first enters into Nesting Zone, and after through the second lower arcuate slot 10, On second curved channel 11 and second, deep-slotted chip breaker 9 flows out, and then produces the vortex flow having clockwise or counterclockwise in Nesting Zone, then to collection Fiber strip in poly-district produces weak twist and gathers effect, plays weak twisting effect, improve yarn quality while effect is gathered in generation.
