Abstract
The utility model is intended to solve the problem that in existing drawing-off structure, yarn easily even breaks because compression chord is excessive and destructurized, a kind of fine spining machine drawing-off structure is provided, comprise feeding group and output group, feeding group comprises bottom roll and is engaged in the roller above bottom roll, output group comprises the belt sheave structure coordinated for about a pair, belt sheave structure comprises two cylinders and the feed belt being connected two cylinders, belt sheave structure also comprises back-up roller, back-up roller from pressure measurement in feed belt on feed belt; Back-up roller has two, and one of them back-up roller position is fixed, and another back-up roller position can regulate; Feed belt is Timing Belt, and the outer circumference surface of cylinder has the groove matched with feed belt.The beneficial effects of the utility model are, yarn compression area is large, yarn uniform force, and without obvious stress concentration phenomenon, yarn is not easily damaged by pressure.
Description
Technical field
The utility model relates to the drawing-off structure in spinning process, particularly relates to a kind of fine spining machine drawing-off structure.
Background technology
Fine spining machine is a link in the middle of the whole flow process of cotton spinning, and its task is that the rove that Speed frames spin is processed into spun yarn, and the key structure completing this work is exactly be drawing-off structure in fine spining machine, and drawing-off structure comprises feeding roller group and delivery roller group.In existing drawing-off structure, feeding roller group and delivery roller group are by a pair roller composition setting up and down, and its middle bottom roller is steel cylinder, and its and sliver contact portion have groove, in order to the gripping of reinforcement to sliver; Top roller is often roller, makes bottom roll form whippy " D " font mouth.
But, in prior art, contacting of roller group and sliver is generally that point cantact is become linear contact lay by elastic deformation by producing during upper bottom roll pressing, contact area increases very limited, and the phenomenon that the pressing of " D " font mouth makes sliver there is stress at the two ends place of pressure mouth concentrates, if grasping force is excessive, then easily damage sliver by pressure, the too small phenomenon that there will be again sliver and skid of grasping force; Moreover the sliver diameter at delivery roller group place is less, be more the increase in the regulation and control difficulty of roller group grasping force.
In existing open file, notification number is had to be CN203559187U, the day for announcing is the Chinese patent literature of 2014.04.23, disclose a kind of fine spining machine drafting system, comprise the first drawing-off roller, first drawing rollers, cradle, second drawing-off roller and the second drawing rollers, described first drawing-off roller is positioned at the front of cradle, first drawing rollers are positioned at the below of the first drawing-off roller, described second drawing-off roller is positioned at the rear of cradle, second drawing rollers are positioned at the below of the second drawing-off roller, second drawing-off roller is arranged with upper leather ring, second drawing rollers are arranged with lower apron, the front of upper leather ring and lower apron is equipped with pressure bar., this utility model shares the partial pressure of drawing-off roller by pressure bar, meets required drafting force, reduce bearing loss and roller wear-out period while reduction energy consumption.The weak point of this technical scheme is, the contact area of roller and yarn is little, must cause larger pressure when meeting grasping force to yarn, and under the effect of the pressure, the structure of yarn is easily destroyed.
Utility model content
For solving the problem that in existing drawing-off structure, yarn easily even breaks because compression chord is excessive and destructurized, the utility model provides that a kind of yarn compression area is large, yarn uniform force, without obvious stress concentration phenomenon, yarn is not easily by the fine spining machine drawing-off structure of damaging by pressure.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of fine spining machine drawing-off structure, comprise feeding group and output group, feeding group comprises bottom roll and is engaged in the roller above bottom roll, output group comprises the belt sheave structure coordinated for about a pair, belt sheave structure comprises two cylinders and the feed belt being connected two cylinders, belt sheave structure also comprises back-up roller, and back-up roller is pressed in feed belt from the inner side of feed belt.Output group is by the plane outside driving belt and yarn contacts, for linear contact lay, under stress after distortion, contact area between yarn and feed belt increases greatly, therefore grasping force that can be larger to yarn effect under less pressure, namely ensure that the gripping drawing-off to yarn, can not damage by pressure because pressure is excessive or yarns again; Back-up roller can support the centre position of feed belt, ensures that feed belt is to the contact surface of yarn and grasping force.
As preferably, back-up roller has two, and one of them back-up roller position is fixed, and another back-up roller position can regulate.The contact area that can control yarn and feed belt by the distance regulated between back-up roller and the pressure be subject to.
As preferably, feed belt is Timing Belt, and the outer circumference surface of cylinder has the groove matched with feed belt.Toothed belt transmission can guarantee two cylinder synchronous axial system, makes feed belt not occur skidding, ensures the movement velocity of yarn, thus ensures the drawing-off effect of yarn.
The beneficial effects of the utility model are: the foundation area of yarn feed belt is large, and grip reliable, yarn uniform force, without obvious stress concentration phenomenon, yarn is not easily damaged by pressure.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1. feeding group, 11. bottom rolls, 12. upper leather rollers, 2. output group, 21. belt sheave structures, 211. cylinders, 212. feed belts, 213. back-up rollers, 3. yarn.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of fine spining machine drawing-off structure, comprise feeding group 1 and output group 2, yarn 33 is sent into from feeding group 1, export from output group 2, the roller 12 that feeding group 1 comprises bottom roll 11 and is engaged in above bottom roll 11, output group 2 comprises the belt sheave structure 21 coordinated for about a pair, belt sheave structure 21 comprises two cylinders 211 and the feed belt 212 being connected two cylinders 211, the material of feed belt 212 is rubber, skin-friction coefficient is large, belt sheave structure 21 also comprises back-up roller 213, back-up roller 213 is pressed in feed belt 212 from the inner side of feed belt 212, back-up roller 213 has two, one of them back-up roller 213 position is fixed, another back-up roller 213 position can regulate, back-up roller 213 is fixed by the elongated rectangular shape mounting groove be fixed on fine voile machine, distance between two back-up rollers 213 can be changed by adjusting its position in mounting groove, thus change feed belt 212 everywhere to the pressure distribution of yarn 3, feed belt 212 is Timing Belt, and the outer circumference surface of cylinder 211 has the groove matched with feed belt 212.
When the utility model uses, first carry out examination drawing-off and observe yarn 3 drawing-off situation, adjust the distance between two back-up rollers 213 according to drawing-off situation, make yarn 3 not occur skidding or pressing the situation of section, the position of fixed support cylinder 213, can use.
