Abstract
The invention discloses an elastic top roller for leather collar doffing. The elastic top roller consists of a roller mandrel, a plurality of bearings, a plurality of spacing sleeves and a plurality of bearing housings, wherein the bearing housings are compounded through three layers of materials; a middle-layer material is an elastic material; inner and outer layer materials are steel materials. When the bearing housings are under the action of external force, the middle-layer elastic material is deformed, so that deviations caused by a machine part machining combination are reduced, pressures on jaws of rollers combined coaxially are balanced, and middle and lower rollers combined coaxially can effectively and stably drive upper and lower doffing leather collars to rotate.
Description
Technical field
The present invention relates to a kind of frame special bearing, particularly relate to a kind of elasticity top roller drawing yarn for apron.
Background technology
The color spun yarn method of Chinese invention patent 201210206260.5 1 kinds of fine spining machine proparea segmentation sections and drafter, propose and replace feeding two groups of rove bars with the middle roller of coaxial combination to front roller intermittence, patent 201220672601.3 1 kinds of upper roller bearings, provide a kind of upper roller bearing supporting with coaxial combination roller, in the roller drafting mechanism of ring throstle, on middle bottom roller and middle top roller, all suit draws yarn apron, control the drawing-off of rove bar, middle top roller and front, rear top roller is different, the roll body of middle top roller is metal roll body, middle top roller relies on spring or air pressure to be pressed on middle bottom roller, by the rotation of middle bottom roller, in drive, under draw yarn apron rotate, on guaranteeing, under draw yarn apron motion stability, roller nip pressure is very important, a kind of upper roller bearing proposed in patent 201220672601.3, solve top roller coaxial configuration problem, but the upper and lower roller utilizing apron to draw yarn is rigid metallic material, in coaxle combination structure situation, because of the processing of multimachine part, installation, use the factors such as wearing and tearing, easily cause outer circle diameter between each coaxial roll body to dimensional discrepancy, therefore each roller nip pressure of coaxial combination can be caused inconsistent, cause coaxial combination roller cannot effectively stably drive each upper and lower yarn apron that draws to rotate, produce rove bar feed quantity and depart from technological requirement phenomenon.
Summary of the invention
The object of the present invention is to provide a kind of elasticity top roller drawing yarn for apron, be applied to the coaxial combination roller adopting apron to draw yarn, ensure that coaxial combination roller draws the effectively stably transmission of yarn apron to upper and lower, realize the effective control to each rove bar.
The technical solution used in the present invention is as follows:
A kind of elasticity top roller drawing yarn for apron, by roller mandrel, some bearings, some covers that spaces, some bearing outside compositions, each bearing outside is transferred on roller mandrel by a bearing, each bearing holder (housing, cover) freely can rotate around roller mandrel, each bearing outside is that trilaminate material is composited, its intermediate layer material is elastomeric material, ectonexine is steel material, bearing outside is under the effect of external force, its intermediate layer elastomeric material produces elastic deformation, the deviation that abatement parts processing combination produces, realize the equilibrium of each nipper pressure of coaxial combination roller, ensure that each bottom roll of coaxial combination can stably drive, under draw yarn apron rotate, effectively carry out pincers to each rove bar to hold, drawing-off.
Further, every one end of roller mandrel, is set with two bearing outsides at least side by side.
Further, keep spacing by the cover that spaces between bearing and bearing, keep the spacing between bearing outside end face to be 0.3 ~ 2mm.
The beneficial effect that the present invention realizes:
A kind of elasticity top roller drawing yarn for apron of the present invention, adopts and has flexible bearing outside, realize the equilibrium of roller nip pressure, can ensure the effective drawing-off of each jaw of combined roller to rove bar, is also the key problem in technology waiting line density Duan Caifang.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation drawing the elasticity top roller embodiment of yarn for apron of the present invention;
Detailed description of the invention
Technical scheme of the present invention is described in detail below in conjunction with accompanying drawing.The embodiment of the present invention is only for concrete grammar is described, the scale of the method is not by the restriction of embodiment.
Embodiment
As shown in Figure 1, a kind of elasticity top roller drawing yarn for apron, by roller mandrel 1, bearing 2, space cover 3, bearing outside 4 forms, each bearing outside 4 is transferred on roller mandrel 1 by a bearing 2, every one end of roller mandrel 1, be set with two bearings and two bearing outsides at least side by side, spacing is kept by the cover 3 that spaces between bearing and bearing, the spacing between bearing outside and bearing outside is kept by the cover 3 that spaces, each bearing outside 4 freely can rotate around roller mandrel 1, each bearing outside 4 is all adopt trilaminate material to be composited, its intermediate layer material 42 is elastomeric material, inner layer material 41, cladding material 43 is steel materials, in utilization, each bearing outside cover is loaded onto and is drawn yarn apron, with corresponding coaxial bottom roll and under draw yarn apron and form jaw, because of the dimensional discrepancy between coaxial upper bottom roll, nipper pressure changes, bearing outside is under the effect of external force, its intermediate layer elastomeric material produces distortion, the deviation that abatement parts processing combination produces, realize the equilibrium of each nipper pressure of coaxial combination roller, ensure the bottom roll of coaxial combination can stably drive each on, under draw yarn apron rotate, effectively carry out pincers to each rove bar to hold, drawing-off.
Claims (3)
1. one kind is drawn the elasticity top roller of yarn for apron, by roller mandrel, some bearings, some covers that spaces, some bearing outside compositions, each bearing outside is transferred on roller mandrel by a bearing, each bearing holder (housing, cover) freely can rotate around roller mandrel, it is characterized in that each bearing outside is that trilaminate material is composited, its intermediate layer material is elastomeric material, ectonexine is steel material, bearing outside is under the effect of external force, its intermediate layer elastomeric material produces elastic deformation, the deviation that abatement parts processing combination produces, realize the equilibrium of each nipper pressure of coaxial combination roller, ensure that each bottom roll of coaxial combination can stably drive, under draw yarn apron rotate, effectively carry out pincers to each rove bar to hold, drawing-off.
2. a kind of elasticity top roller drawing yarn for apron according to claim 1, is characterized in that every one end of roller mandrel, is set with two bearing outsides at least side by side.
3. a kind of elasticity top roller drawing yarn for apron according to claim 1, is characterized in that keeping spacing by the cover that spaces between bearing and bearing, keeps the spacing between bearing outside end face to be 0.3 ~ 2mm.。
