[0002] Winding is the last step in spinning and the first step in weaving, and plays the role of a "bridge" connecting the previous and the next steps. The winder is a special equipment for spinning. Through its specific function, the winder realizes the transformation of yarn from bobbin yarn or small bobbin tail yarn to large bobbin yarn, increases the yarn capacity of the yarn package, and improves the quality of the yarn.

[0003] The winding machine connects the bobbins with smaller capacity or small bobbins to make bobbins with larger capacity. The capacity of a large bobbin is equivalent to more than 20 bobbins or small bobbins; this helps to reduce the downtime of the subsequent process and improve production efficiency.

At this time, the bobbin on the next bobbin foot seat 14 and the yarn at the negative pressure yarn suction mechanism 17 will correspond to the suction nozzle position and feed it, realizing the automatic feeding of the device to the bobbin winder. At the same time, because a plurality of mounting holes 19 are provided on the surface of the turntable 13, and the bobbin foot seat 14 and the mounting holes 19 are connected by bolts, the device can quickly disassemble and adjust the number of the bobbin foot seats 14 on the surface of the turntable 13, and because the connection method is too large, the bobbin can be quickly disassembled and adjusted.

At this time, the partition 22 will block the yarns and reduce direct contact between the yarns; when the yarn on the bobbin on the surface of the bobbin foot seat 14 is installed on the surface of the negative pressure yarn suction mechanism 17, the yarn can be passed through the yarn guide hook 3, and the yarn guide hook 3 will provide an additional limiting effect on the movement of the yarn; when the motor 12 is started, the turntable 13 will rotate, and at this time the bull's eye bearing 4 will provide additional support to the surface of the turntable 13, thereby improving the stability of the turntable 13 during rotation. At the same time, the bull's eye bearing 4 will also rotate with the rotation of the turntable 13, so that the turntable 13 will encounter less resistance when rotating. The staff can rotate the first screw 5 to change the height of the chassis 1 from the ground, and the height of the remaining components will also change accordingly, so that the device can adapt to a wider range of production needs; when it is necessary to put yarn bobbins of different inner diameters on the surface of the bobbin foot seat 14, the staff can rotate the second screw 6 to squeeze the bobbin foot seat 14.
