Abstract
A kind of elastic top roller drawing yarn for apron, if being made of roller mandrel, dry bearing, several gauge sets, several bearing outsides, bearing outside is that trilaminate material is combined, wherein interlayer material is elastic material, ectonexine is steel material, bearing outside is under the effect of external force, wherein interbed elastic material is deformed, cut down the deviation that parts processing combination generates, the equilibrium for realizing each nipper pressure of coaxial combination roller ensures that the middle bottom roller of coaxial combination can effectively, steadily drive each yarn apron that draws above and below to rotate.
Description
Technical field
The present invention relates to a kind of frame special bearing more particularly to a kind of elastic top rollers for drawing yarn for apron.
Background technique
A kind of spinning frame proparea of Chinese invention patent 201210206260.5 is segmented section coloured silk spun yarn method and draft mechanism,
It proposes and alternately feeds two groups of rove items, patent 201220672601.3 1 to front roller intermittence with the middle roller of coaxial combination
Kind upper roller bearing provides a kind of upper roller bearing matched with coaxial combination roller, the roller draft machine of ring throstle
In structure, on middle bottom roller and middle top roller, suit draws yarn apron, controls the drawing-off of rove item, middle top roller and forward and backward upper sieve
Difference is drawn, the roll body of middle top roller is metal roll body, and middle top roller is pressed on middle bottom roller by spring or air pressure, in
The rotation of bottom roll drives and draws the rotation of yarn apron above and below, it is ensured that draws the stability of yarn apron movement, roller nip pressure above and below
It is critically important；A kind of upper roller bearing proposed in patent 201220672601.3 solves the problems, such as top roller coaxial configuration, but benefit
The upper and lower roller for drawing yarn with apron is rigid metallic material, in coaxle combination structure, because multimachine part processing, installation,
Using factors such as abrasions, the outer circle radial direction dimensional discrepancy between each coaxial roll body is easily caused, therefore will cause each sieve of coaxial combination
It draws nipper pressure inconsistent, causes coaxial combination roller that each yarn apron that draws above and below effectively can not steadily be driven to rotate, generate thick
Sliver feed quantity deviates technique and requires phenomenon.
Summary of the invention
The purpose of the present invention is to provide a kind of elastic top rollers for drawing yarn for apron, draw yarn applied to using apron
Coaxial combination roller guarantees coaxial combination roller to drawing yarn apron above and below and being effectively steadily driven, and realization has each rove item
Effect control.
The technical solution adopted by the invention is as follows:
A kind of elastic top roller drawing yarn for apron, if if by roller mandrel, dry bearing, several gauge sets, dry bearing
Housing composition, for each bearing outside through a bearing switching on roller mandrel, each bearing holder (housing, cover) can be around roller core
Axis is freely rotated, each bearing outside is that trilaminate material is combined, and wherein interlayer material is elastic material, and ectonexine is steel
Material, under the effect of external force, wherein interbed elastic material generates flexible deformation to bearing outside, and abatement parts processing combination produces
Raw deviation realizes the equilibrium of each nipper pressure of coaxial combination roller, ensures that each bottom roll of coaxial combination can steadily drive
Above and below draw yarn apron rotation, effectively to each rove item carry out pincers hold, drawing-off.
Further, every one end of roller mandrel, at least there are two bearing outsides for suit side by side.
Further, it is covered between bearing and bearing by gauge and keeps spacing, keep the spacing between bearing outside end face
For 0.3~2mm.
It is that the present invention realizes the utility model has the advantages that
A kind of elastic top roller drawing yarn for apron of the present invention is realized using flexible bearing outside
The equilibrium of roller nip pressure can ensure effective drawing-off of each jaw of combined roller to rove item, and wait line densities Duan Caifang
Key problem in technology.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram for the elastic top roller embodiment for drawing yarn for apron of the present invention；
Specific embodiment
Below in conjunction with attached drawing, the technical schemes of the invention are described in detail.The embodiment of the present invention, should only for illustrating specific method
The scale of method should not be limited by the examples.
Embodiment
As shown in Figure 1, a kind of elastic top roller for drawing yarn for apron, covers 3, bearing by roller mandrel 1, bearing 2, gauge
Housing 4 forms, each bearing outside 4 is transferred on roller mandrel 1 by a bearing 2, every one end of roller mandrel 1, until
There are two bearing and two bearing outsides for few suit side by side, keep spacing by gauge set 3 between bearing and bearing, pass through gauge
Set 3 keeps the spacing between bearing outside and bearing outside, each bearing outside 4 can be freely rotated around roller mandrel 1, often
One bearing outside 4 is combined using trilaminate material, and wherein interlayer material 42 is elastic material, inner layer material 41, outer
Layer material 43 is steel material, and in utilization, each bearing outside set, which is loaded onto, draws yarn apron, with corresponding coaxial bottom roll and under draw
Yarn apron constitutes jaw, and because of the dimensional discrepancy between coaxial upper bottom roll, nipper pressure changes, and bearing outside is in external force
Under effect, wherein interbed elastic material is deformed, and the deviation that abatement parts processing combination generates realizes that coaxial combination roller is each
The equilibrium of nipper pressure ensures that the bottom roll of coaxial combination can steadily drive each yarn apron that draws above and below to rotate, effectively to each
Rove item carry out pincers hold, drawing-off.
Claims (3)
1. a kind of elastic top roller for drawing yarn for apron, if if outside by roller mandrel, dry bearing, several gauge sets, dry bearing
Set composition, for each bearing outside through a bearing switching on roller mandrel, each bearing outside can be around roller core
Axis is freely rotated, it is characterized in that each bearing outside is that trilaminate material is combined, wherein interlayer material is elastic material, interior
Outer layer is steel material, and under the effect of external force, wherein interbed elastic material generates flexible deformation to bearing outside, and abatement parts add
The deviation that work combination generates, realizes the equilibrium of each nipper pressure of coaxial combination roller, ensures that each bottom roll of coaxial combination can be steady
Surely drive above and below draw yarn apron rotation, effectively to each rove item carry out pincers hold, drawing-off.
2. a kind of elastic top roller for drawing yarn for apron according to claim 1, it is characterized in that roller mandrel is each
