The narrow groove-type hollow roller compact spinning air flow guide piece comprises arc-shaped air inlet passages of negative pressure air flow at the left and right ends, a pair of supporting seats in bilateral symmetry and fixed holes in the supporting seats. The air flow guide piece is embedded inside the middle bearing of the cap bar via the fixed holes in the supporting seats, fixing and installation of the air flow guide piece are realized; the air flow guide piece adopts polymethyl methacrylate material to be formed at one time through processing and plastic injection; the air flow guide piece is an arc-shaped cuboid, the length is between 20 to 25mm, the width is between 8 to 10mm, and the thickness is between 2 to 5mm. The air flow guide piece has the advantages that the installation is convenient, the operation is simple, easy and practical, and the utilization efficiency of the negative pressure air flow of the narrow groove-type hollow roller compact spinning can be effectively improved.
Description
Technical field
The utility model relates to ring spinning new technical field, relates to specifically a kind of air-flow prerotation vane that is applicable to narrow slot type hollow roller compact spinning.
Background technology
Advance of Compact Spinning Technology mainly increases a fiber control zone before traditional drafting system, and that fiber is coagulated to constriction is poly-, reaches the effect that reduces or eliminate twist triangle zone.Compact spinning technology can be divided into two kinds of negative pressure collecting and machinery centralizations, and it is the form of gathering being most widely used in current Advance of Compact Spinning Technology that suction type gathers, and its mechanism is to utilize negative-pressure air-flow laterally to condense the fibre bundle by control zone.But because the compact spinning mode that adopts air-flow to realize on ring throstle to gather completely need to increase the consumption of the energy, under the close prerequisite of compacting effect, improvement cost, reducing the use procedure energy has become the key point of compact spinning technology spread success or failure.Narrow slot type hollow roller compact spinning is an important branch of negative pressure collecting compact spinning system, air-flow prerotation vane is one of distinctive system element of narrow slot type hollow roller compact spinning, cover the whole region of gathering, its effect is that negative-pressure air-flow is introduced and gathered district, improves the compacting effect to yarn.
For this, the utility model provides a kind of air-flow prerotation vane that is applicable to narrow slot type hollow roller compact spinning, and this prerotation vane can effectively increase the force controlled in yarn motion process, improves the compacting effect of yarn, effectively improves the utilization ratio of gathering negative pressure.
Summary of the invention
The purpose of this utility model provides a kind of narrow slot type hollow roller compact spinning air-flow prerotation vane, by improving the flow path of negative-pressure air-flow in tight-spinning collecting district, increase the force controlled in the motion process of yarn, effectively improve the compacting effect of yarn, improve the utilization ratio of gathering negative pressure.
In order to achieve the above object, the utility model relates to a kind of narrow slot type hollow roller compact spinning air-flow prerotation vane, be arranged on the support bar top of narrow slot type hollow roller compact spinning cap bar, gathering in district between resistance twist rubber roll and front rubber roll, be close to narrow slot type hollow roller surface.Described air-flow prerotation vane comprises the fixing hole on the arc inlet channel of two ends, left and right negative-pressure air-flow, symmetrical a pair of supporting seat, supporting seat, described air-flow prerotation vane is embedded into by the fixing hole on supporting seat in the intermediate bearing of cap bar, realize the fixed installation of air-flow prerotation vane, described stream prerotation vane adopts polymethyl methacrylate materials time processing injection molded, described air-flow prerotation vane is shaped as arc cuboid, length is between 20-25mm, width is between 8-10mm, and thickness is between 2-5mm.
The utility model can be used for narrow slot type hollow roller compact spinning, applicable to the spinning of cotton fiber, cotton type chemical fibre etc., this air-flow prerotation vane is easy for installation, Simple And Practical, can effectively improve the negative-pressure air-flow utilization ratio of narrow slot type hollow roller compact spinning, reduces system energy consumption.
