According to the component adding instruction, the controller controls the driving mechanism to be opened and closed so that the corresponding functional components enter the rotary cup through the conveying pipeline. When the outer layer is wound with the core yarn, the functional components in the rotor cup act on the wrapped yarn of the rotor cup to be compounded to obtain the wrapped yarn with corresponding functions.

The specific flow of adding the functional components is described in detail below in conjunction with fig. 2 to 4.

Referring to fig. 2, a process of preparing a wrap yarn by a combined mechanism formed by connecting the rotor spinning machine spinning unit 100 to the external feeding mechanism 200 is illustrated.

Specifically, the traction electret is an electret having a counter electrode, and a charge property opposite to the aforementioned excited net charge substance is formed by the electret, so that the adsorbed charged component moves toward the traction portion. In this way, by utilizing the long-term stored charge characteristic of the electret, a charge property opposite to that of the above-described net charge substance is formed in the traction portion, and the net charge substance is moved to the traction portion, so that it is unnecessary to provide an energizing line.

Preferably, the traction part is provided with at least two groups of traction electrodes or traction electrets, each group of traction electrodes or traction electrets comprises one or more traction electrodes or traction electrets, at least one group of traction electrodes or traction electrets is positioned at an effective adsorption position at any moment to play a role in adsorption, and the positions of the plurality of groups of traction electrodes or traction electrets are adjusted by a shifting mechanism. Referring to fig. 9, taking two sets of traction electrets as an example, a first set of traction structures 600a and a second set of traction structures 600b which are isomorphic (have the same structure) may be included, the first set of traction structures 600a and the second set of traction structures 600b may be connected through a displacement mechanism 610, and the positions of the first set of traction structures 600a and the second set of traction structures 600b may be adjusted through the displacement mechanism 610, so that at any moment, one set of traction structures is located at an effective adsorption position 700 to play an adsorption role, and the other set of traction structures is located at an idle standby state.

When the traction electrode or the traction electret group with the adsorption function at present needs to be cleaned, the traction electrode or the traction electret is driven to leave from the effective adsorption position through the shifting mechanism, and meanwhile, a new traction electrode or the traction electret group is driven to enter into the effective adsorption position.

As shown in fig. 9, the manner in which the first set of traction structures 600a are positioned at the effective suction location 700 for suction and the second set of traction structures 600b are in an idle standby state is illustrated. In this manner, when one set of traction structures is contaminated with charged components and cannot effectively adsorb the charged components, another set of traction structures that are not contaminated and are in an idle standby state may be adjusted to the effective adsorption position 700 to continue the adsorption. Then cleaning the polluted group of traction structures, removing the charged components, and putting the traction structures into an idle standby state.

The displacement mechanism 610 may be a mechanism that adjusts the position of the traction structure based on horizontal movement, or may be a mechanism that adjusts the position of the traction structure based on rotational movement. The displacement mechanism 610 of the rotation adjustment mechanism employed in fig. 7, the displacement mechanism 610 brings the first set of traction structures 600a and the second set of traction structures 600b into rotational motion, thereby adjusting the traction structures located in the effective suction position 700.

Referring to fig. 10, an adjustment of the displacement mechanism 610 of fig. 9 to move the first set of traction structures out of the effective suction position 700 and to position the second set of traction structures in the effective suction position 700 by rotating counterclockwise is illustrated.

Preferably, referring to fig. 9 and 10, a cleaner 800 is provided corresponding to the traction electrode or the traction electret group, and during the displacement process of the traction electrode or the traction electret group, which is rotational displacement in fig. 9, the cleaner 800 on the left side is in contact with the contaminated first group of traction structures 600a, and the cleaning of the first group of traction structures 600a is completed by cleaning the charged components adsorbed on the first group of traction structures 600a by the cleaner 800. Similarly, when the second set of traction structures need cleaning, the displacement mechanism 610 rotates clockwise (see the rotating arrow in fig. 10) such that the cleaner 800 on the right side contacts the contaminated second set of traction structures, cleaning the second set of traction structures by the cleaner 800 cleaning the charged components adsorbed on the second set of traction structures.

The cleaner 800 may be used in combination with one or more of brush, adhesive, wind-powered suction, and other cleaning methods.

On the other hand, the cleaner 800 may be connected to the component supply chamber of the component adding unit through a recovery line, and the cleaned charged component is discharged and then recovered to the component supply chamber through the recovery line. The charged component is charged (or static removed) in a neutralizing way, for example, an ion blower generates an air flow with ions, and the air flow blows on the negatively charged component to neutralize the static so as to make the component neutral; it is also possible to bring the components to neutrality by contacting the charged components with a metal mesh to conduct away the net charge.
