Description

Intelligent preparation method and preparation device of rotor spinning fasciated yarn

Technical Field

The invention relates to the technical field of composite yarn spinning, in particular to an intelligent preparation method and device of fasciated yarns in rotor spinning.

Background

The wrapped yarn is also called covering yarn, which is a composite yarn. The wrapping yarn is composed of two kinds of fibers, namely filament yarn wrapped on a short fiber (wool type or cotton type) yarn core or short fiber wrapped on a filament yarn core, and the wrapping yarn wraps the core yarn in a spiral mode, and is characterized by uniform evenness, bulkiness and fullness, smooth yarn with less hairiness, high strength and less broken ends. Of course, there are also wrapped yarns composed of three types of fibers, such as wrapping a staple fiber around a filament to form a core and then wrapping another filament; or wrapping a filament inner core with a filament outer core, and then wrapping with short fibers. The wrapping yarn has the characteristics of each component due to the special structure.

At present, the methods for spinning fasciated yarns are many, and mainly comprise a hollow spindle method, an air vortex method, a self-twisting fasciated yarn and a rotor spinning fasciated yarn. Among them, for rotor spinning fasciated yarn, the rotor spinning composite yarn system integrates the excellent wearability of short fiber and the functionality of long filament, and is one of the key development directions of rotor spinning. The rotor spinning machine mainly comprises a rotor, a false twisting disc, a yarn-drawing tube, a yarn-drawing roller, a fiber conveying channel, a cotton feeding roller, a carding roller, a trash discharging device and the like, wherein fibers transferred to the rotor from a carding cavity are condensed by utilizing the centrifugal force generated when the rotor rotates at a high speed to form strands (fiber rings), and the strands are twisted to form yarn strips. In the traditional production process of the rotor spinning fasciated yarn, short fibers are generally fed into a rotor, long fibers are fed from the axis of the bottom of the rotor, the long fibers lean against the wall of the rotor and enter a cotton condensing groove under the action of centrifugal force, the long fibers are subjected to false twisting when being drawn out, and the fed short fibers are coated outside the long fibers to form the fasciated yarn. However, in the above production process, the phenomenon of broken ends is serious, and the difference of uniformity of the coating effect is large.

The prior art also provides a technical solution in which a core yarn is spun by a rotor spinning machine through a feed sliver and filaments are wound on the outer layer. Specifically, the feeding amount of the filament is controlled by a filament guide, a tension control device and a feeding roller, and the filament is sucked and fed into a revolving cup with a central hole and is wrapped on the surface of short fiber to form wrapped yarn by generating internal and external pressure difference through high-speed revolution of the revolving cup with the central hole during spinning. However, the above production process has the following drawbacks: the spun fasciated yarn is a yarn core formed by short fibers, and the filaments are positioned on the surface layer, so that the yarn is single in structure and property.

Along with the increasing living standard of people, the development of functional textiles is more and more emphasized, and the development of functional yarns is one of the important means for processing the functional textiles. How to provide an intelligent, flexible, simple process, low manufacturing cost and multifunctional yarn with multiple functions based on rotor spinning fasciated yarn is a technical problem which needs to be solved urgently at present.

In another embodiment, the traction portion employs a traction electret as the charge-adsorbing structure. Specifically, the pulling electret is an electret having a counter electrode, and a charge property opposite to the excited net charge substance is formed by the electret, so that the attracted charged component moves in the direction toward the pulling portion.

Referring to fig. 8, taking the example of providing two sets of pulling electrets, the two sets of pulling structures may include a first set of pulling structures 600a and a second set of pulling structures 600b that are isomorphic (identical in structure), the first set of pulling structures 600a and the second set of pulling structures 600b may be connected by a shifting mechanism 610, and the positions of the first set of pulling structures 600a and the second set of pulling structures 600b may be adjusted by the shifting mechanism 610, so that at any time, one set of pulling structures is located at the effective suction position 700 for suction, and the other set of pulling structures is in an idle standby state.

Fig. 8 illustrates the manner in which the first group of traction structures 600a is positioned in the active suction position 700 for suction, while the second group of traction structures 600b is in an idle standby state. Thus, when one group of the traction structures is polluted by the charged component and cannot effectively adsorb the charged component, the other group of the traction structures which are not polluted and are in an idle standby state can be adjusted to the effective adsorption position 700 to continue to play the adsorption role. Then, the contaminated group of traction structures is cleaned, and after the charged components are removed, the traction structures are put into an idle standby state.

By analogy, when the second group of traction structures need to be cleaned, the shifting mechanism 610 rotates clockwise, so that the cleaner 800 on the right side is in contact with the polluted second group of traction structures, the charged components adsorbed on the second group of traction structures are cleaned through the cleaner 800, and the second group of traction structures are cleaned.

The cleaner 800 may be used in one or more of a brush, a stick-on suction, a wind suction, and the like.

Preferably, the cleaning device 800 may further connect to the component supply chamber of the component adding unit through a recycling line, so that the cleaned charged component can be recycled to the component supply chamber through the recycling line after being de-charged.
