[0029] The output end of the first motor 2 penetrates through the first shell 31 and is fixedly connected with the first bevel gear 21. The first shell 31 is uniformly provided with six prismatic shafts 312 which are rotatably connected with the first shell 31. One end of each six prismatic shaft 312 is fixedly connected with a second bevel gear 311 which is meshingly connected with the first bevel gear 21.

[0031] The guide assembly 4 comprises a tripod 41 fixedly connected to one side of the mounting frame 11. The tripod 41 is uniformly provided with sliding grooves 411.

When the helical gear 322 rotates, the transmission shaft 323 can be driven to rotate, and the drive roller 5 can be driven to rotate. After the paper tube for winding is installed on the winding shaft 6, one end of the yarn is fixed to the paper tube. Under the action of the springs 43, the sliding blocks 42 drive the three transmission shafts 323 to make the drive roller 5 adhere to the outer surface of the paper tube. The rotation of the drive roller 5 can drive the paper tube to rotate for winding.

[0033] One end of the winding shaft 6 is rotatably connected with the tripod 41 through a shaft, and the other end of the shaft penetrates through the tripod 41 and is connected with a driving disc 61.

[0035] The upper part of the bottom plate 1 is also provided with an adjusting assembly 8, the adjusting assembly 8 comprises a second motor 81 fixedly connected on one side of the mounting frame 11, the output end of the second motor 81 is fixedly connected with a spur gear 82, the adjusting assembly 8 further comprises a disc 83 rotationally connected on the shaft on one side of the winding shaft 6, the rear of the disc 83 is provided with a gear ring, and the gear ring is meshingly connected with the spur gear 82.

[0036] The outer side of the disc 83 is uniformly distributed with first and second protrusions 84 and 85, and the first and second protrusions 84 and 85 correspond to the transmission shaft 323, before winding, the second motor 81 drives the disc 83 to rotate, and then through the first protrusion 84, the radial distance between the three groups of driving rollers 5 is increased, at this time, the paper tube is conveniently installed on the winding shaft 6, when the winding is completed, the disc 83 rotates, and the radial distance between the three groups of driving rollers 5 is increased through the first protrusion 84, and the paper tube wound with the yarn is conveniently taken out.

[0037] Specifically, when winding, the second motor 81 drives the disc 83 to rotate, and the first protrusion 84 increases the radial distance between the three groups of drive rollers 5. At this time, the paper tube is installed on the winding shaft 6, and then the yarn is fixed on the paper tube through the guide ring 75. Then the second motor 81 is reset, and under the action of the spring 43, the slider 42 promotes the three groups of transmission shafts 323 to make the drive rollers 5 adhere to the outer surface of the paper tube. Then the first motor 2 is started, and when the first motor 2 rotates, it can drive the second bevel gear 311 to rotate through the first bevel gear 21. When the second bevel gear 311 rotates, it drives the hexagonal shaft 312 to rotate. When the hexagonal shaft 312 rotates, it drives the face gear 321 to rotate. When the face gear 321 rotates, it drives the bevel gear 322 to rotate. When the bevel gear 322 rotates, it drives the transmission shaft 323 to rotate. The transmission shaft 323 drives the drive roller 5 to rotate, and the linear speed of the winding is the same. When the winding shaft 6 is winding, the reciprocating lead screw 72 is driven to rotate through the driving disc 61, the belt 77 and the transmission disc 76. When the reciprocating lead screw 72 rotates, it drives the cam pair 74 and the guide ring 75 to move transversely and reciprocally. In the initial stage of winding, the angular velocity of the paper tube is fast, and the moving speed of the guide ring 75 is fast. When the yarn on the paper tube becomes more, the three groups of drive rollers 5 move outward, the linear speed of the winding shaft 6 is not convenient, the angular velocity becomes small, and the moving speed of the guide ring 75 becomes small accordingly, so that the yarn is uniformly wound on the paper tube outside the winding shaft 6.
