The arrangement is such that the other end of the compression spring 6 is fixed to the adjacent roller 2, and the other end of the roller 2 is provided with a groove 5 which cooperates with the conical end of the plug 3. The plug 3 is located inside the groove 5. When spinning moves between the two rollers 2 and pressure is applied to the conical surface of the plug 3, the plug 3 can be pressed into the roller 2 through the compression spring 6. After spinning pushes the plugs 3 between the rollers 2 into the rollers 2 in sequence, it can be prevented from moving between the rollers 2 and the bottom roller 8. A double-headed output power box 7 is installed on one side of one of the mounting frames 1 away from the bottom roller 8. The two output ends of the double-headed output power box 7 are respectively fixed to the bottom roller 8 and the adjacent roller 2. When the plug 3 is inserted into the groove 5, the multiple rollers 2 rotate synchronously.

[0027] A power telescopic rod 9 is installed on the side of the other mounting frame 1 away from the bottom roller 8 , a wire pressing structure 4 is installed on the upper end of the power telescopic rod 9 , and the split roller 2 is located below the wire pressing structure 4 .

[0028] The wire pressing structure 4 includes two bottom plates 42, two pressing plates 41 and a fork frame 43. The upper end of the power telescopic rod 9 is fixed to the fork frame 4. The two bottom plates 42 are fixed to the fork frame 43. The mounting frame 1 connected to the power telescopic rod 9 is slidably connected with a vertical rod 45. The upper end of the vertical rod 45 is fixedly connected to the fork frame 43 to ensure that the fork frame 43 can only move in the vertical direction. The two pressing plates 41 are respectively located above the two bottom plates 42. The two pressing plates 41 are arranged parallel to the two bottom plates 42. The two pressing plates 41 are symmetrically distributed front and back with the axis of the bottom roller 8.

The outer surfaces of the two pressing plates 41 are slidably sleeved with a sleeve frame 412. The sleeve frame 412 is slidably sleeved on the outer surface of the bottom plate 42. The inner height of the sleeve frame 412 is equal to the sum of the thickness of the pressing plate 41 and the thickness of the bottom plate 42. When the sleeve frame 412 is sleeved between the bottom plate 42 and the pressing plate 41, the bottom plate 42 and the pressing plate 41 can be used for spinning clamping. A transverse telescopic rod 411 is fixed to one side of the sleeve frame 412 close to the fork frame 43. The other end of the transverse telescopic rod 411 is fixedly connected to the bottom surface of the adjacent bottom plate 42. The transverse telescopic rod 411 supports the sleeve frame 412 after it is separated from the bottom plate 42 and the pressing plate 41, and at the same time limits the moving path of the sleeve frame 412.

The force presses the spinning into between the two sub-rollers 2. When the spinning contacts the conical surface of the plug 3, the pressure of the spinning applies pressure to the plug 3 to compress the compression spring 6. After the plug 3 is separated from the groove 5, the spinning can move to the bottom of the plug 3. After the spinning moves to the bottom of all the plugs 3, the spinning moves to between the bottom roller 8 and the sub-rollers 2, and then the double-headed output power box 7 is started to rotate the bottom roller 8 and the sub-rollers 2 to pull and transport the spinning. When the spinning is transported, the pressure plate 41 and the bottom plate 42 are in a separated state and are separated from the clamping of the spinning.
