[0022] The content of the utility model can be more easily understood by referring to the following detailed description of the preferred implementation method of the utility model and the included embodiments. Unless otherwise defined, all technical and scientific terms used in this paper have the same meaning as generally understood by those skilled in the art to which the present application belongs. When there is a conflict, the definition in the specification shall prevail.

[0023] Example 1:

[0024] The prior art yarn twisting machine as shown in Figure 4 has vertical first yarns in the yarn spindles, and second yarns around the yarn spindles, when twisting is performed, the second yarns rotate around the first yarns to twist the yarns. In order to reduce the size of the equipment and save costs, the distance between the multiple yarn spindles is as small as possible, and is separated by a partition to prevent the yarns from being wound together, but the second yarns are easily contaminated when rotating by touching the partition.

[0025] As shown in Figure 1 , a twisting device and a yarn twisting machine, comprising: a twisting spindle 1 and a ring cover 2, the ring cover 2 is sleeved on the outside of the twisting spindle 1, the twisting spindle 1 has vertical first yarns 3, the twisting spindle 1 and the ring cover 2 have second yarns 4, the twisting spindle 1 is used for twisting the first yarns 3 and the second yarns 4.

[0026] The twisting spindle 1 comprises a spindle rod 11, a twisting disc 12 and a bobbin 13, the spindle rod 11 is in the bobbin 13, and the twisting disc 12 is at the bottom of the bobbin 13. The inside of the spindle rod 11 is a hollow structure, and a yarn guide ring 14 is arranged on the inner wall of the spindle rod 11. The twisting disc 12 is provided with a twisting channel, and the twisting channel is in communication with the inside of the spindle rod 11. The first yarns 3 pass through the yarn guide ring 14 vertically upward in the spindle rod 11.

[0027] A gap is arranged between the ring cover 2 and the bobbin 13, and the second yarns 4 are in the gap. The difference between the inner diameter of the ring cover 2 and the outer diameter of the bobbin 13 is in the range of 5cm-15cm, and the preferred difference is 8cm. The second yarns 4 are limited by the ring cover 2 when winding, preventing the second yarns 4 from touching the surrounding equipment or partition, and the difference between the inner diameter of the ring cover 2 and the outer diameter of the bobbin 13 can ensure the normal operation of the equipment and the constraint of the running track of the first yarns 3.

[0028] As shown in Figures 2-3 , a yarn twisting machine, comprising a machine frame body 5, a yarn feeding device 6, a yarn guide device 7, a winding device 8 and a twisting device, the yarn feeding device 6 is arranged at the top of the machine frame, the twisting device is connected with the yarn feeding device 6 through the yarn guide device 7, and the winding device 8 is above the twisting device. The yarn feeding device 6, the yarn guide device 7, the twisting device and the winding device 8 are provided with multiple ones, and are arranged in sequence on the machine frame body 5. A partition 51 is arranged between adjacent twisting devices, and the partition 51 is fixedly installed on the machine frame body 5. The partition 51 is provided with a fixed plate 52 in diameter, and the fixed plate 52 is used for fixedly installing the ring cover 2. The yarn feeding device 6 is used for feeding yarn to the yarn guide device 7, the yarn guide device 7 guides the yarn into the twisting device, and the winding device 8 is used for winding the twisted yarn. The yarn feeding device 6, the yarn guide device 7 and the winding device 8 are prior art, and the specific structure of the present application will not be described.

[0029] Working principle: the yarn feeding device 6 delivers yarn to the yarn guide device 7, the yarn guide device 7 guides the yarn into the twisting device, the first yarn 3 passes through the spindle 11, and the second yarn 4 is in the gap between the bobbin 13 and the ring cover 2 and is limited by the ring cover 2, so the second yarn 4 will not touch the surrounding partition plate 51. After twisting, it is wound by the winding device 8.
