[0028] The buffer assembly 21 is arranged at the front side of the winding machine body 1 to reduce the friction force when winding the yarn. The buffer assembly 21 includes two mounting plates 211 fixedly mounted on the front side of the winding machine body 1. A disc 218 is fixedly mounted on the opposite sides of the two mounting plates 211. A plurality of notches 216 are provided inside the disc 218, and the plurality of notches 216 are evenly distributed inside the disc 218 in a circumferential manner. A limiting disk 215 is movably mounted inside the plurality of notches 216. A connecting rod 214 is fixedly mounted on one side of the limiting disk 215. A mounting frame 217 is fixedly mounted on one end of the connecting rod 214. A movable roller 212 is movably mounted on the inner side of the mounting frame 217. A wire groove 213 is provided on the outer side of the movable roller 212. The wire groove 213 can prevent the yarn from shaking left and right on the outer side of the movable roller 212. A first spring 219 is fixedly mounted on one side of the plurality of notches 216.

[0029] The winding assembly 22 is arranged on the top surface of the winding machine body 1 and is used to fix the reel to wind the yarn;

One end of the first spring 219 is fixedly installed on one side of the limit plate 215, and the elastic force of the first spring 219 can make the yarn in a taut state when the connecting rod 214 is pressed against the movable roller 212. When the yarn squeezes the movable roller 212, it will be contracted to the inside of the slot 216 through the connecting rod 214 to prevent the yarn from breaking. One end of the connecting rod 214 movably passes through the inside of several slots 216 and is fixedly installed on the bottom surface of the mounting frame 217.

When in use, the yarn is attached to the wire groove 213, and one end of the yarn is fixed to the outside of the drum. Then the winding assembly 22 is started to wind the yarn around the outside of the drum. While winding the yarn, the elastic force of the first spring 219 can resist the limit plate 215 through the connecting rod 214 to make the movable roller 212 tighten the yarn. When the yarn is too tight, it will resist the movable roller 212 to make the connecting rod 214 inserted into the slot 216 to prevent the yarn from breaking. At the same time, multiple movable rollers 212 can increase the contact points of the yarn, reduce its pressure and friction, and avoid excessive wear of the yarn, which affects its quality and life.
