Abstract
The utility model patent disclose a kind of realize machinery and the dual device gathered of negative pressure, a kind of machinery centralization cover is installed additional by the hollow roller surface having narrow groove on surface, realize the first time machinery centralization before the twisting of the fiber strip after drawing-off to gather with second time negative-pressure air-flow, thus improve compacting effect, improve yarn quality.
Description
Technical field
The utility model relates to spinning new technical field, specifically a kind of realize machinery and the dual device gathered of negative pressure.
Background technology
Compact spinning is a kind of Advanced Spinning Technologies carrying out spinning on the ring throstle improved, and it by increasing a fibre deposition district to improve yarn quality before ring throstle draw-gear.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 this ubiquitous transformation of type compact spinning system and maintenance cost compared with large, consumable accessory is many, the life-span is short, the more high phenomenon of energy consumption.Therefore, roller type compact spinning comes into one's own at present gradually, its in energy consumption, machine material consumption and system maintenance cost comparatively lattice apron type compact spinning there is some superiority.
For this, the utility model provide a kind of realize machinery and the dual device gathered of negative pressure.This device hollow roller and machinery centralization cover, hollow roller comprises roller cover and bored roll, roller cover and bored roll integral forming, one of middle part along the surface of roller cover circumferentially has the narrow groove of continuously arranged transverse direction, machinery centralization cover comprises left adapter sleeve and right adapter sleeve, left adapter sleeve and right adapter sleeve are circular, left adapter sleeve is connected by connecting plate with right adapter sleeve, horn mouth is added above connecting plate, horn mouth comprises front port and rear port, front port and the angle between rear port connecting line and the vertical diameter of hollow roller are at 30-45.Between, horn mouth port diameter reduces gradually along front port and rear port connecting line direction.During use, machinery centralization cover is tightly placed on hollow roller by left adapter sleeve and right adapter sleeve, first fiber strip after drawing-off enters horn mouth, in the horn mouth that port diameter reduces gradually, be subject to mechanical type gather active force, the first time realized before yarn twisting is gathered, and yarn out enters hollow roller surface afterwards by horn mouth rear port, and what be subject to negative-pressure air-flow gathers active force, realize yarn twisting before second time gather, and after through twisting resultant yarn.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of realize machinery and the dual device gathered of negative pressure, realize the first time machinery centralization before the twisting of the fiber strip after drawing-off to gather with second time negative-pressure air-flow, thus improve compacting effect, improve yarn quality.
In order to solve the problem, the technical scheme that the utility model is taked is: a kind of realize machinery and the dual device gathered of negative pressure, comprise hollow roller and machinery centralization cover, described hollow roller comprises roller cover and bored roll, described roller cover and bored roll integral forming, one of middle part along the surface that described roller overlaps circumferentially has the narrow groove of continuously arranged transverse direction, described machinery centralization cover comprises left adapter sleeve and right adapter sleeve, described left adapter sleeve and right adapter sleeve are circular, described left adapter sleeve is connected by connecting plate with right adapter sleeve, horn mouth is added above described connecting plate, described horn mouth comprises front port and rear port, described front port and the angle between rear port connecting line and the vertical diameter of hollow roller are at 30-45.Between, described bell-mouthed port diameter reduces gradually along front port and rear port connecting line direction, and described machinery centralization cover is tightly placed on hollow roller by left adapter sleeve and right adapter sleeve.
During use, machinery centralization cover is tightly placed on hollow roller by left adapter sleeve and right adapter sleeve, first fiber strip after drawing-off enters horn mouth, in the horn mouth that port diameter reduces gradually, be subject to mechanical type gather active force, the first time realized before yarn twisting is gathered, and yarn out enters hollow roller surface afterwards by horn mouth rear port, and what be subject to negative-pressure air-flow gathers active force, realize yarn twisting before second time gather, and after through twisting resultant yarn.
After adopting said structure, the first time machinery centralization before the twisting of the fiber strip after drawing-off can be realized and gather with second time negative-pressure air-flow, thus improve compacting effect, improve yarn quality.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model can realize machinery and the dual apparatus for collecting of negative pressure.
Fig. 2 is machinery centralization nested structure schematic diagram of the present utility model.
Detailed description of the invention
Shown in Fig. 1 and Fig. 2, a kind of realize machinery and the dual device gathered of negative pressure, comprise hollow roller 2 and machinery centralization cover 1, wherein hollow roller 2 comprises roller cover 3 and bored roll 4, roller cover 3 and bored roll 4 integral forming, overlap the middle part on the surface of 3 along roller one circumferentially has the narrow groove 5 of continuously arranged transverse direction, machinery centralization cover 1 comprises left adapter sleeve 6 and right adapter sleeve 7, left adapter sleeve 6 and right adapter sleeve 7 are circular, left adapter sleeve 6 is connected by connecting plate 8 with right adapter sleeve 7, horn mouth 9 is added above connecting plate 8, horn mouth 9 comprises front port 10 and rear port 11, front port 10 and the angle between rear port 11 connecting line and the vertical diameter of hollow roller 2 are at 30-45.Between, the port diameter of horn mouth 9 reduces gradually along front port 10 and rear port 11 connecting line direction, and machinery centralization cover 1 is tightly placed on hollow roller 2 by left adapter sleeve 6 and right adapter sleeve 7.
During use, machinery centralization cover 1 is tightly placed on hollow roller 2 by left adapter sleeve 6 and right adapter sleeve 7, first fiber strip after drawing-off enters horn mouth 9, in the horn mouth 9 that port diameter reduces gradually, be subject to mechanical type gather active force, the first time realized before yarn twisting is gathered, and yarn out enters hollow roller 2 surface afterwards by horn mouth 9 rear port 11, and what be subject to negative-pressure air-flow gathers active force, realize yarn twisting before second time gather, and after through twisting resultant yarn.
