Abstract
The utility model patent discloses a kind of double-layer hollow roller device.This device comprises central hollow cover and hollow roller layer, hollow roller layer comprises hollow roller skin and hollow roller internal layer, bar-shaped trough is had at hollow roller superficies, hole is had on hollow roller internal layer surface, hole is circle, rhombus or ellipse, or interlaced arrangement, and hollow roller skin and hollow roller internal layer are stainless steel, close between hollow roller skin and hollow roller internal layer and connect, centre is hollow structure.Effectively can increase the systematicness control action to negative-pressure air-flow by said structure, improve compacting effect calmly.
Description
Technical field
The utility model relates to spinning new technical field, specifically a kind of double-layer hollow roller device.
Background technology
RING SPINNING is the topmost spun yarn mode of production of current China, and domestic current ring spinning number of spindles, more than 1.3 hundred million ingots, accounts for 2/3 of global spindle sum.Compact spinning is a kind of Advanced Spinning Technologies improved RING SPINNING, and become the most heat subject in spinning field at present, development practice for many years tells us: the world of following RING SPINNING belongs to compact spinning.At present, the compact spinning type that main flow uses in the world comprises lattice apron type (mainly comprising German Sussen tri-roller lattice apron type, Japanese Toyota tetra-roller lattice apron type), roller type (Switzerland's profit reaches the COM4 of Rieter), punching apron type (mainly comprising Zinser punching apron formula), mechanical type (mainly comprising Switzerland Carlos Roscraft magnetic centralization type compact spinning system), and lattice apron type, roller type and punching apron type belong to negative-pressure air-flow and gather mode.Wherein, Roscraft machinery centralization type compact spinning system due to the at present use at home of the reasons such as varietal adaptation difference (being generally only applicable to 60Ne with the spinning of yarn under working) less; Zinser punch apron formula due to varietal adaptation poor (being generally only applicable to wool spinning) and need complete machine to introduce, expensive (average every 1500 yuan, ingot), therefore use scale is at home less.Therefore, what occupy mainstream market at present is lattice apron type compact spinning.But in use mainly there is the problems such as operating cost is higher, maintaining is complicated, the life-span is short in lattice apron type compact spinning.Roller type compact spinning comes into one's own gradually, its in energy consumption, machine material consumption and system maintenance cost comparatively lattice apron type compact spinning there is some superiority, the COM4 of Rieter is most typical roller type compact spinning system, but this system is gathered surface of roller and is adopted pore structure, easy blocking, need often cleaning, and require higher to the humiture in workshop, increase maintenance cost.For this, the utility model provides a kind of double-layer hollow roller device.This device comprises central hollow cover and hollow roller layer, hollow roller layer comprises hollow roller skin and hollow roller internal layer, bar-shaped trough is had at hollow roller superficies, hole is had on hollow roller internal layer surface, hole is circle, rhombus or ellipse, or interlaced arrangement, and hollow roller skin and hollow roller internal layer are stainless steel, close between hollow roller skin and hollow roller internal layer and connect, centre is hollow structure.Effectively can increase the systematicness control action to negative-pressure air-flow by said structure, improve compacting effect calmly.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of double-layer hollow roller device, thus effectively increases the systematicness control action to negative-pressure air-flow, improves compacting effect calmly.
In order to solve the problem, the technical scheme that the utility model is taked is: a kind of double-layer hollow roller device, comprise central hollow cover and hollow roller layer, described central hollow cover is connected with the integration of hollow roller layer, described hollow roller layer comprises hollow roller skin and hollow roller internal layer, bar-shaped trough is had at described hollow roller superficies, hole is had on described hollow roller internal layer surface, described hole is circular, rhombus or ellipse, or interlaced arrangement, described hollow roller skin and hollow roller internal layer are stainless steel, close between described hollow roller skin and hollow roller internal layer and connect, centre is hollow structure, distance between described hollow roller skin and hollow roller internal layer is between 3mm-5mm.
Above-mentioned hollow roller is adopted to comprise inside and outside double-layer structure, superficies are narrow groove internal layer surface is simultaneously pore structure, effectively can increase the systematicness control action to negative-pressure air-flow, effectively can solve susceptible to plugging problem in the use procedure that single borehole structure or strip hole structure cause simultaneously, thus improve compacting effect, improve yarn quality.
Accompanying drawing explanation
Fig. 1 is the utility model double-layer hollow roller device structural representation.
Detailed description of the invention
A kind of double-layer hollow roller device, comprise central hollow cover 1 and hollow roller layer 2, wherein, central hollow cover 1 is connected with hollow roller layer 2 integration, hollow roller 2 layers comprises hollow roller outer 3 and hollow roller internal layer 4, bar-shaped trough 5 is had on outer 3 surfaces of hollow roller, hole 6 is had on hollow roller internal layer 4 surface, hole 6 is circular, rhombus or ellipse, or interlaced arrangement, hollow roller outer 3 and hollow roller internal layer 4 are stainless steel, close between hollow roller outer 3 and hollow roller internal layer 4 and connect, centre is hollow structure, distance between hollow roller outer 3 and hollow roller internal layer 4 is between 3mm-5mm.
In spinning process, main body rove by rear roller drawing-off to feeding, after the proparea drawing-off in middle district, enter hollow front roller, when yarn is through hollow roller layer 2, because hollow roller internal cavities exists negative pressure, enter in the hollow structure between hollow roller outer 3 and hollow roller internal layer 4 by the hole on hollow roller internal layer 4 surface, then by the narrow groove suction airstream on outer 3 surfaces of hollow roller, fiber is made to realize gathering before twisting, reduce twist triangle zone area, improve resultant yarn comprehensive quality.
