Dynamic part, is widely used in the mechanisms such as drawing-off, combing, conveying, by effect can be divided into drawing rollers, feed roller, calender roller,
Worker rollers etc..Drawing rollers are the major parts of spinning machine drafting mechanism, and roller Pliers is formed in pairs by top roller and bottom roll
Mouthful, it holds sliver or fibre web carries out drawing-off, the quality of roller influences the uniformity of output sliver.Be not added with illustrate when, usually carry
The roller arrived refers to drafting lower roller, it is the steel elongated shaft that outer circle has groove, annular knurl or smooth surface, often along spinning machine
Overall length several single-units are connected into permutation, be actively driven by transmission mechanism.
Traction roller is generally fluted roll, and the section of fluted roll is defined as the gear shape with trapezoidal groove.It is right
In existing convention trench roller, in use, since surface of roller friction coefficient is excessive, surface of roller and fibre frictoin meeting
Electrostatic is generated, fiber or whole root item are easy on roller, cause broken end or yarn defect.Its surface grooves of traditional fluted roll
It is larger to the damage of fiber, a large amount of staple fiber can be caused in operation process, and its shell is cast with the pig iron or steel, weight
Greatly, high energy consumption.And the both ends generally use pivot and screw of existing textile roller are fixed, the willow catkins flying in the air in cotton yarn be easy into
Enter at pivot connection, influence the rotation of roller, service life is short, and maintenance cost is big, and down time is long.Therefore, how to send out
Reduce groove while raising the advantages of roller groove increases frictional force to rub to the damage of fiber and reduction surface of roller with fiber
Harm caused by wiping the electrostatic that contact generates is an industry problems.
Recent domestic rubs to increasing using bionics techniques, drag reduction and desorption theory etc. have carried out numerous studies, makes
It is standby gone out corresponding bionic surface.If the researcher of Univ Manchester UK imitates the bristle configurations of gecko vola, develop
Go out a kind of conveyer belt that cohesive force is extremely strong, and has come into operation.Numerous research experiences both domestic and external show that the climbing of biological foot is attached
The mechanism of wearing can be imitated and utilized by industrial products.In nature, cicada easily can overcome its own gravity to be adsorbed in trunk
With on leaf.Studies have shown that cicada vola has microstructure as shown in Figure 7, there are many pit shape structures and in gradient on surface
Distribution, elasticity modulus also distribution gradient, is increased by outer layer to inner layer elasticity modulus in gradient.Existing research confirms this ladder
Degree elastic construction can be effectively increased contact friction force.Thus it gains enlightenment, it is assumed that selected more in roller and fiber surface contact position
Soft rubber sleeve is sleeved on roller shaft, and rubber sleeve is made of gradient elastic material, is increased successively to inner layer elasticity modulus by outer layer
Add, then while can meeting increase roller with fiber contacts frictional force, roller can be reduced to fibre since rubber surface is softer
The cutting damage of dimension.
