The path of the yarn after the roller structure passes out is as follows: the roller structure, the upper hollow shaft, the upper twisting rotating disc, the lower hollow shaft, the yarn guide tube and the yarn collecting rubber tube, under the way, yarns are transmitted in a U shape, the upper twisting rotating disc assembly 300 and the lower twisting rotating disc assembly 400 are driven to rotate by the twisting motor 700, and the chenille yarns which are twisted once are transmitted through the lower hollow shaft 420 and the yarn guide tube 510 and are twisted twice in the same direction, so that the aim of twisting twice is fulfilled, the twisting efficiency is higher than that of the traditional chenille yarn machine, the production efficiency of the traditional chenille yarn machine is greatly improved, and the yield is improved.

The upper twisting rotating plate assembly 300 and the lower twisting rotating plate assembly 400 are both provided with wire passing holes, specifically, as shown in fig. 4-5, the upper hollow shaft 320 is of a hollow structure, a first wire passing hole 321 is formed in the side surface of the upper hollow shaft 320, meanwhile, a second wire passing hole 311 is also formed in the upper twisting rotating plate 310, and after the yarn penetrates into the upper hollow shaft 310, the yarn passes out of the first wire passing hole 321 and passes through the second wire passing hole 311 of the upper twisting rotating plate 310 downwards.

The lower hollow shaft 420 has a hollow structure, a fourth wire passing hole 421 is formed in the side surface of the lower hollow shaft 420, and a third wire passing hole 411 is formed in the lower twisting rotating disc 410, so that the yarn passes through the third wire passing hole 411 and the fourth wire passing hole 421 after passing out of the second wire passing hole 311, enters the lower hollow shaft 420, passes out of the top of the lower hollow shaft 420, and passes upward through the yarn guide tube 510 and the yarn collecting rubber tube 610.

Further, the twisting motor 700 is mounted on the outer bracket 100 through a motor bracket 710, and the twisting motor 700 is connected with the upper twisting rotating disc assembly 300 and the lower twisting rotating disc assembly 400 through a belt transmission mechanism 720 respectively, so as to drive the upper twisting rotating disc assembly 300 and the lower twisting rotating disc assembly 400 to synchronously rotate.

The method specifically comprises the following steps: belt transmission mechanisms 720 are respectively arranged at two ends of the twisting motor 700, and the belt transmission mechanisms 720 comprise: a driving wheel 721 arranged on the output shaft of the twisting motor and a driven wheel 722 arranged on the upper hollow shaft 320/the lower hollow shaft 420, wherein a belt 723 is arranged between the driving wheel 721 and the driven wheel 722, and the twisting motor 700 drives the upper twisting rotating disc assembly 300 and the lower twisting rotating disc assembly 400 to synchronously rotate when in operation so as to twist yarns.

The twisting motor 700 can be used for arbitrarily regulating the speed, the rotating speeds of the twisting motor 700 are different, and the twisting effects of the yarns are different, so that the rotating speeds are regulated according to the twist required by customers, and different requirements of the customers on the yarns are met.

In one embodiment, the inner bracket 200 is in a frame shape, and is not in direct contact with the outer bracket 100, the inner bracket 200 is mounted through the upper hollow shaft 320 and the lower hollow shaft 420, the magnet 140 is arranged between the inner bracket 200 and the outer bracket 100, and the inner bracket 200 and the outer bracket 100 are relatively positioned through the magnet 140, so that the inner bracket 200 cannot rotate along with the upper hollow shaft 320 and the lower hollow shaft 420; specifically, the magnet 140 may be a permanent magnet, and has opposite magnetism, so that the inner bracket 200 and the outer bracket 100 can be attracted to each other, and positioning can be achieved. Meanwhile, since the yarn guide assembly 500 and the yarn assembly 600 are mounted on the inner bracket 200, the yarn guide assembly 500 and the yarn assembly 600 can be prevented from rotating horizontally, so that the use is not affected; in summary, when the upper twist rotor assembly 300 and the lower twist rotor assembly 400 rotate, the outer bracket 100 and the inner bracket 200 maintain relative positioning, and the yarn guide assembly 500 and the yarn assembly 600 do not rotate along with each other, thereby ensuring the twisting effect.

Also, as can be seen from the above, the yarn finally passes out of the lower hollow shaft 420 at the center of the entire rotation position because the position of the yarn outlet end is not affected even when the upper and lower twist rotor assemblies 300 and 400 are rotated, i.e., the twisting process does not affect the collection of the yarn.

Further, the yarn guiding tube motor 520 is mounted on the inner bracket 200, and is connected with the yarn guiding tube 510 through a belt transmission mechanism and drives the yarn guiding tube 510 to rotate.

In one embodiment, since the upper and lower twisting rotating disc assemblies 300 and 400 are rotated during twisting, and the upper and lower twisting rotating disc assemblies 300 and 400 are supported by the inner frame 200 but are relatively positioned and not rotated, the layout problem of the electric wires needs to be solved, and the power supply to the yarn guide assembly 500 can be realized without affecting the twisting of the yarn, so that:

In one embodiment, as shown in fig. 6, the pick-and-place mechanism 620 includes: the handles 621 are symmetrically arranged and connected to the handles 621 at two ends of the yarn collecting rubber tube 610, the handles 621 are mounted on the inner support 200, the guide rail 210 is arranged on the inner wall of the inner support 200, the handles 621 are mounted on the guide rail 210 through the sliding blocks 220, the guide rail 210 is vertically arranged, then the handles 621 can move up and down along the guide rail 210, meanwhile, springs (not shown in the figure) are connected to the handles 621, and the springs provide the elasticity for the yarn collecting rubber tube 610 to move towards the yarn guiding tube 510, so that the yarn collecting rubber tube 610 clings to the yarn guiding tube 510.

Alternatively, the spring may be modified to have a spring plate or the like.

In use, the yarn collecting rubber tube 610 is tightly attached to the yarn guiding tube 510, and is rotated by friction force with the yarn guiding tube 510 to collect yarn, and when the yarn collecting operation is started, the handle 621 moves up to a high position along the guide rail 210 under the action of the spring, and during the yarn collecting operation, the larger the yarn on the yarn collecting rubber tube 610 is, the larger the diameter of the yarn collecting rubber tube 610 (the diameter including the yarn is here) is, the handle 621 is pushed to gradually move down along the guide rail 210 until the yarn is moved to the tail end of the guide rail 210.

Optionally, a triggering structure may be disposed at the end of the guide rail 210, and when the handle 621 moves to the end of the guide rail 210 to trigger the triggering structure, an alarm may be sent to remind the user to replace the yarn collecting rubber tube 610; the warning mode can be light, sound and the like.
