Rotor spinning is to complete by negative pressure in the revolving cup of high speed rotary and cup a kind of spinning method that fiber is carried, condensed and close, twist resultant yarn, is the most ripe, the most widely used spinning technique of technology in current various novel spinning.Press the mode that in revolving cup, negative pressure produces, can be divided into self air exhaust and the large class of bleeder two.Between the revolving cup rim of a cup of air suction type rotor spinning machine and defeated fine upper channel, leave certain gap, blower fan is taken the air-flow in revolving cup away from this gap, the negative pressure forming in cup makes the filament after shredding enter in revolving cup through defeated fine passage along with filling into air-flow, filament is under the centrifugal action of revolving cup High Rotation Speed, along the smooth inner wall slippage of revolving cup, arrive in the collection surface at revolving cup maximum inner diameter place, and close and form fibrae circulares bar, ribbon after joint success leaves collection surface with tail yarn, and be subject to the height of revolving cup to go back to twisting resultant yarn simultaneously, again through navel, doffing tube is drawn out and the resultant yarn of reeling is rolled up.The yarn formation structure of the T-shaped revolving cup that cotton spinning is conventional is similar to ring spun yarn, has the feature powerful high, bar makes a good job of, filoplume is few.
As shown in Figure 1, the cross section of the collection surface 5 of T-shaped revolving cup 2 is an acute angle, can make the cohesion of fibrae circulares bar closely, and the cohesive force between fiber increases, and yarn strength improves.The base of this acute angle forms an annular, this annular place plane L(is hereinafter referred to as collection surface baseplane) and stretch between the left side (being navel top) of the navel 1 in revolving cup rim of a cup and leave certain gap, when revolving cup High Rotation Speed, the impurity and the dust that with fiber, enter in revolving cup are dumped into revolving cup collection surface under centrifugal action, owing to leaving gap between navel top and collection surface baseplane, therefore tail yarn 3 does not contact with revolving cup collection surface baseplane, and tail yarn can not be taken away the impurity in collection surface and dust when navel 1 is drawn out.Along with the accumulation of time, in collection surface, laying dust can increase, and collection surface shape becomes Rouno Cormer Pregrinding Wheel by wedge angle, causes the cohesion difficulty of fiber.As collection surface cleans not in time, yarn evenness will variation, powerful decline, and the impurity in collection surface and dust also can affect and enter being uniformly distributed of fiber in collection surface, affects the transmission of the twist, make dynamically powerful reduction, end breakage rate increases, and when a lot of and local shedding of collection surface laying dust, will cause yarn defect, when serious, can form slub yarn, cause very large economic loss.
Rotor spinning machine is towards high speed, high yield future development at present, and rotational speed of rotor increases substantially, and in the situation that centrifugal force strengthens, the collection surface laying dust of revolving cup can be more obvious.Meanwhile, due to the significantly rising of labor cost, electric cost and the cost of material of textile industry, enterprise profit obviously glides.For reducing costs, some enterprises turn to short flannel how high containing assorted secondary raw material, regenerated fiber production yarn.But what short flannel was many, height contains assorted secondary raw material and regenerated fiber brings is that revolving cup collection surface laying dust is serious, the bar of yarn is done variation, powerful decline, breaking end increases, and operative employee's labour intensity obviously strengthens, the low inferior technical barrier of production efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of self-cleaning structure of rotor spinning machine, in revolving cup operation process, can make tail yarn contact with the baseplane of revolving cup collection surface, in time the impurity in collection surface and dust are taken away, unlikely impurity and the dust accumulation of allowing, the acute angle shape of maintenance collection surface.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A self-cleaning structure for rotor spinning machine, comprises T-shaped revolving cup and defeated fine upper channel, and T-shaped revolving cup has collection surface, on described defeated fine upper channel, navel is installed, and in the rim of a cup of described navel in revolving cup, it is characterized in that:
