Abstract

The invention relates to the textile industry, in particular to a device for ringless yarn, and makes it possible to improve the quality of the yarn. The spinning rotor of the device is fixed at the end of the drive shaft, having an axial channel for insertion into the spinning rotor of the screwed-on component. On the opposite end of the spinning rotor, the end of the drive shaft is fixed to the sleeve, inside which the inner sleeve is coaxially mounted through the blades. When the shaft rotates with the blades, they are withdrawn from the cavity between the end of the shaft and the end of the internal sleeve of the cavity facing it through the internal air from the atmosphere again into the atmosphere, preventing it from entering the spinning rotor and breaking it aerodynamic regime. 4 il.

The invention relates to the textile industry and relates to a device for endless strand with the production of two-component yarn.

The purpose of the invention is to improve the quality of life.

Figure 1 shows the device, an axial section; figure 2 - part of the drive shaft with bushings, a longitudinal section; on fig.Z - internal sleeve with blades; in Fig. A, view A in Fig. 3.

The device includes a housing 1, where a spinning rotor 2 is placed and a sampling and fiber feeding unit (not shown) through feed channel 3 to the spinning rotor 2. The latter with air vents 4 is mounted on the end of the drive shaft 5 mounted by bearings 6 In case 1, the drive shaft 5 has an axial channel 7 for insertion into the spinning rotor of the screwed-on component. In the housing 1, with the side of the spinning rotor opposite to the drive shaft 5, a chewing tube 8 is installed coaxially with it.

At the opposite end of the spinning rotor 2 of the drive shaft 5, an outer sleeve 9 is fixed coaxially with it, inside which an inner sleeve 10 is connected coaxially with it, connected to the outer sleeve by means of inclined blades 11. A cavity is formed between the end of the inner sleeve 10 and the end of the drive shaft 5 12. The shaft 5 is driven by a belt (not shown) through the sleeve 9.

The device works as follows.

The separated fibers in the feed channel 3 created by the negative pressure in the spinning rotor 2 are transported to the spinning rotor, where from

fibers are formed by a tape that twists with a threaded component fed through sleeve 10 and channel 7 into the yarn, which is output from the spinning rotor through the tube 5. To create the necessary aerodynamic conditions for yarn formation, the air from the spinning rotor is removed through vents 4 When the drive shaft rotates at a certain angle to its axis of rotation and with a predetermined pitch, the blades 11 retract the air entering the internal sleeve 9 from the atmosphere into the cavity 12 through the gaps between the blades s in the atmosphere. Thus, the blades create a vacuum of air in the cavity 12, corresponding to the vacuum inside the spinning rotor, but since the diameter of the channel 7 die is much smaller than its length U, air is not allowed to flow from the cavity into the cavity of the spinning rotor and back. In this connection, with the constant suction force created by the air suction system in the spinning rotor, the balance of aerodynamic flows is not disturbed by the presence of a channel in the drive shaft for feeding the screwed component, which contributes to the normalization of the formation of the fibrous mousy and its twisting with the component and improvement

quality of the finished two-component yarn at a constant energy consumption per spin.

Claims (1)

Thus, the presence at the end of the drive shaft, from the input side into its axial channel, of a screwed component of the bushes with blades, prevents air from the atmosphere through the channel into the spinning rotor without disturbing the aerodynamic regime in it. Claims of the Invention A device for ringless spinning comprising a sampling and feeding unit for fibers in a spinning rotor mounted at the end of a drive shaft, provided with an axial channel for insertion into the spinning rotor of a screwed component, and located coaxially with the spinning rotor with its opposite drive pattern. The shaft of the side of the chewing tube is characterized in that, in order to improve the quality of the yarn, it contains two sleeves mounted coaxially one to the other and connected to one another by means placed between They have blades, while the outer sleeve is fixed on the opposite end of the spinning rotor end of the drive shaft coaxially with it forming between the end and the end of the inner sleeve of the cavity. 77 J Fig1 Fig 2 Type A Fi.Z
