[0025] An embodiment of the present application, as shown in Figures 1 to 3 , comprising:

[0026] The vertical plate 1 is provided with a driving motor 21 on one side of the vertical plate, and the driving motor shaft 22 of the driving motor penetrates through the vertical plate and is located on the other side of the vertical plate;

[0027] A thread pressing wheel 3 is arranged on the motor shaft; the thread pressing wheel is pressed on the driving motor shaft, so that the yarn can be prevented from slipping, and the yarn can be collected at the same running speed as the fabric of the collecting roller. As shown in the figure, the thread pressing wheel maintains the pressure of the thread pressing wheel on the driving motor shaft by relying on the pressure wheel of the spring. As shown in the figure, the thread pressing wheel is installed on the vertical plate through a bracket, and a guide rod is arranged thereon, and a spring is sleeved on the guide rod. A handle is arranged on one side of the bracket, and the thread pressing wheel can be lifted from the driving motor shaft to facilitate the yarn to be put between the thread pressing wheel and the driving motor shaft.

[0030] The pressure adjusting cover cooperates with the pressure adjusting spring to adjust the friction force of the contact part of the friction disc and the take-up wheel, so that a small friction force exists between the contact part of the friction disc and the take-up wheel; thus, the rotation of the take-up motor does not affect the take-up speed of the driving motor, and the rotation of the take-up wheel is only driven by the friction force of the contact part and the friction disc, so that when the take-up speed of the take-up motor is greater than the rotation speed of the driving motor (the rotation speed of the take-up roller), the contact part of the friction disc and the take-up wheel slip, and the take-up is not performed.

[0032] A control device is arranged to control the rotation speed of the driving motor to be adapted to the rotation speed of the take-up roller according to the monitoring result of the speed measuring device; the control device can be a PLC or a single-chip microcomputer, etc., and mainly calculates the rotation speed of the driving motor according to the rotation speed or the linear speed monitored by the speed measuring device, so as to make the take-up speed of the driving motor the same as the fabric running speed on the take-up roller.

[0033] Further, a handle 7 is arranged on the take-up wheel, so as to facilitate manual operation of the take-up wheel.

[0034] As a further improvement of the present application, a driving wheel with a diameter corresponding to that of the take-up roller is arranged on the shaft of the driving motor, so that the rotation speed of the driving motor can be the same as the rotation speed measured by the speed measuring device, without the need to convert it into the linear speed.

[0036] The rotation speed of the take-up roller is monitored in real time by the speed measuring device;

[0037] The rotation speed of the driving motor is controlled according to the monitored rotation speed of the take-up roller, so as to make the linear speed of the shaft or the driving wheel of the driving motor the same as the linear speed of the take-up roller;

[0038] The take-up motor drives the take-up wheel to take up the yarn passing through the driving wheel in real time.
