The present embodiment is described in detail below with reference to fig. 2 to 6.

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.

The second bobbin 15 is wound with the monofilament or yarn 17 and when the spinning unit 100 completes the piecing, the second yarn guiding motor 18 of the external feeding mechanism 200 is started to operate, and the monofilament or yarn 17 on the second bobbin 15 is fed into the rotor 11 of the spinning unit through the monofilament or yarn feeding channel 21.

During the process of the yarn (wrapping yarn) in the spinning cup 11 being led out of the package through the yarn guiding tube 9, the monofilament or yarn 17 fed by the external feeding mechanism is automatically wound on the surface of the core yarn (i.e. the rotor yarn 10) to form the wrapping yarn 7. The package yarn is drawn out through the yarn drawing tube and wound by the first yarn drum while forming the package yarn.

The first yarn detector 6 and the second yarn detector 20 may also be in communication connection with the aforementioned controller, and the yarn breakage signal of the rotor spinning machine spinning unit 100 is collected by the first yarn detector 6 and sent to the controller, and the monofilament or yarn breakage information of the external feeding mechanism 200 is collected by the second yarn detector 20 and sent to the controller. The controller can control the broken ends according to the broken yarn signals, namely, control the first yarn guiding motor and the feeding motor of the spinning unit to stop working, and control the second yarn guiding motor of the peripheral mechanism to stop working while the yarn supporting rod lifts the first yarn cylinder. The controller can also control the various structures of the spinning unit 100 and the peripheral feeding mechanism 200 to re-enter the operational state after the splice command is obtained.

In the wrapping yarn compounding step, one or more functional components are inputted into the rotor by the component adding device 300 so that the functional components are distributed on the wrapping yarn 7; meanwhile, in order to enable more functional components to act on the wrapping yarn, the corresponding component supply chamber or delivery pipe may be further provided with a charge release portion and a traction portion, by which the functional components are caused to act on the wrapping yarn by the mutual cooperation of the charge release portion and the traction portion, as shown in fig. 3 and 4.

After the controller 400 obtains the functional component addition command, the driving mechanism 312 can be controlled to start generating air flow or jet force to enable the functional component to enter the inside of the rotary cup 11 through the conveying pipeline 32.

Referring to fig. 8, the first set of traction structures 600a is mounted on an upper left side portion 612b-1 of the upper left side portion of the support frame, and the second set of traction structures 600b is mounted on an upper left side portion 612b-2 of the upper right side portion of the support frame, and the first set of traction structures and the second set of traction structures 600b are spaced apart by a spacing region 612 b-3.

The effective adsorption position 700 is located at a predetermined fixed position, such as being disposed directly opposite the outlet of the delivery line outlet. At any time, one group of traction structures is positioned at the effective adsorption position 700 to play a role in adsorption, and the other group of traction structures is in an idle standby state. Thus, when one group of traction structures is polluted by the charged component and cannot effectively adsorb the charged component, the other group of traction structures which are not polluted and are in an idle standby state can be adjusted to an effective adsorption position to continuously play a role in adsorption. The contaminated set of traction structures is then cleaned and, after removal of the charged components, put into an idle state for use.

Referring to fig. 9, the cleaner 800 includes a left cleaner section and a right cleaner section.

When the first set of traction structures 600a need to be moved out of the effective adsorption position, the supporting frame can be controlled by the rotation driving motor to rotate leftwards, the supporting frame drives the first set of traction structures 600a and the second set of traction structures 600b to rotate leftwards together, and in the leftward shifting process of the first set of traction structures 600a, the left cleaning part 800 can clean the charged components adsorbed on the first set of traction structures 600a, and meanwhile, the second set of traction structures 600b can shift towards the effective adsorption position, as shown in fig. 10.

When the second set of traction structures is required to be moved out of the effective adsorption position, the support frame can be controlled to rotate rightwards by the rotary driving motor, see the direction of the rotary arrow illustrated in fig. 10. The supporting frame drives the first set of traction structures 600a and the second set of traction structures 600b to rotate rightwards together, and in the rightward shifting process of the second set of traction structures 600b, the right cleaning part 800 can clean the charged components adsorbed on the second set of traction structures 600b, and meanwhile, the first set of traction structures 600a shift to the effective adsorption position.

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 device 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.

In another embodiment of the invention, an intelligent cleaning method of the composite yarn component adding device is also provided. The method comprises the following steps:

s100, acquiring a dirt detection trigger instruction.

The dirt detection triggering instruction can be manually triggered based on a user or periodically and automatically triggered based on a preset time period.

S200, starting a dirt detector, detecting the amount of charged components adsorbed on a traction electrode or a traction electret through the dirt detector, and judging whether the amount of the charged components exceeds a preset dirt standard value.

And S300, triggering a cleaner to clean the traction electrode or the charged component adsorbed on the traction electret under the condition that the preset dirt standard value is exceeded.
