[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The present application embodiment discloses a yarn doubling and undoing structure. Figure 1-Figure 4A yarn doubling and undoing structure comprises: a mounting frame 1; an undoing mechanism rotatably arranged on the side wall of the mounting frame 1 and used for rotating and undoing the yarn; a driving mechanism fixedly arranged on the mounting frame 1; a thread collecting mechanism rotatably arranged on the top of the driving mechanism and used for winding and collecting the undoing yarn.

[0022] Reference Figure 1 The retracting and merging mechanism includes a rotating frame 2, a rotating shaft 1 3, a rotating shaft 2 4, a first connecting frame 5 and a first wire collection drum 6;

[0023] A rotating frame 2 is rotatably connected to the side wall of the mounting frame 1 by a rotating shaft 1 3, so that the rotating frame 2 can be rotated in the vertical direction on the side wall of the mounting frame 1, and a connecting frame No. 1 is rotatably connected to the other end of the rotating frame 2 by a rotating shaft 2 4, so that the connecting frame No. 1 can also be rotated in the horizontal direction through the rotating shaft 2 4, so that the first wire collection drum 6 mounted on the connecting frame No. 1 can be rotated in the vertical and horizontal directions when the yarn is unwinding, so that the yarn wrapped around the outer wall of the first wire collection drum 6 can be unwound from the outer wall of the first wire collection drum 6 by rotation.

[0024] Reference Figure 1 and Figure 2 The driving mechanism includes a receiving frame 7, a motor 11, a transmission gear 12 and a transmission rack 13;

[0025] A supporting frame 7 is fixedly connected to the mounting frame 1, and a plurality of transmission gears 12 are rotatably connected to the bottom of the supporting frame 7, and a transmission rack 13 is meshingly connected to the side walls of the plurality of transmission gears 12, so that when one of the transmission gears 12 rotates, the remaining plurality of transmission gears 12 can all rotate synchronously. At the same time, a motor 11 is fixedly connected to the top of the mounting frame 1 at the bottom side of the supporting frame 7, and the output end of the motor 11 is fixedly connected to the bottom of one of the transmission gears 12, so that the motor 11 can rotate to drive the plurality of transmission gears 12 to rotate synchronously.

[0026] Reference Figure 1 and Figure 3 The wire collection mechanism includes a rotating shaft 3 8, a second connecting frame 9, a second wire collection drum 10 and a limit bar 15;

[0027] By rotatably connecting a plurality of rotating shafts 3 8 inside the receiving frame 7, a plurality of second connecting frames 9 can be rotatably connected to the top of the receiving frame 7 through the plurality of rotating shafts 3 8, and the bottom of the second connecting frame 9 is fixedly connected to the transmission gear 12, so that when the transmission gear 12 is rotated, the second connecting frame 9 can be synchronously rotated;

[0028] At the same time, a second wire collection drum 10 is sleeved on the outside of the second connecting frame 9, and a plurality of limit strips 15 are fixedly connected to the outer wall of the second wire collection drum 10. The two ends of the limit strips 15 are fixed to the outer wall of the second wire collection drum 10, and the middle position is not fixedly connected to the outer wall of the second wire collection drum 10, so that the yarn that is withdrawn and separated can be quickly fixed to the outer wall of the second wire collection drum 10 through the limit strips 15, thereby facilitating the second wire collection drum 10 to stably rotate, wind and collect the withdrawn yarn.

[0029] Reference Figure 3 and Figure 4 A plurality of limiting grooves 14 are provided on the inner wall of the second hub 10, and a plurality of arc strips 16 are fixedly connected to the outer wall of the second connecting frame 9, so that when the second hub 10 is sleeved on the outside of the second connecting frame 9, the limiting grooves 14 and the arc strips 16 can be engaged with each other to perform a fast limiting docking connection;

[0030] At the same time, a spring 17 is fixedly connected between the inner wall of the arc strip 16 and the outer wall of the second connecting frame 9, so that the arc strip 16 has better elastic support ability when in use, and can better limit and clamp the second hub 10;

[0031] In addition, the connection structures of the first connecting frame 5 and the second connecting frame 9 are the same, and the connection structures of the first wire hub 6 and the second wire hub 10 are the same.

[0032] The implementation principle of a yarn joining and unjoining structure in an embodiment of the present application is as follows: by providing a mounting frame 1, the mounting frame 1 can be used for fixed support when the yarn is unjoined. During the yarn unjoining process, the first collection drum 6 wound with the yarn to be unjoined is first sleeved on the No. 1 connecting frame 5, and then the unjoined and separated yarns are fixedly connected to the outer walls of several second collection drums 10 respectively. At this time, the motor 11 is started, and the several transmission gears 12 driven by the motor 11 and the No. 2 connecting frame 9 are rotated, and the separated yarns are rotated and collected by the several second collection drums 10. When the rotating frame 2 is winding and collecting the second collection drum 10, the rotating shaft 1 3 and the rotating shaft 2 4 will drive the first collection drum 6 to rotate due to the pulling of the yarn, so as to facilitate the rotation and dispersion of the yarn wrapped around the outer wall of the first collection drum 6, and perform the yarn joining and unjoining work.
