AI Technical Summary
Technical Problem
Existing yarn rolls are prone to knotting during the unwinding process due to changes in traction force, and traditional tensioning wheels are not effective in controlling this.
Method used
The cylinder-driven pressing device ensures that the pressing pads are tightly attached to the surface of the yarn roll through the cooperation of upper and lower springs. The linear displacement of the pressing pads is achieved by using sliders and guide rails to prevent the yarn roll from rotating freely and to achieve stable yarn feeding.
Benefits of technology
This effectively prevents the yarn roll from knotting due to inertia during the unwinding process, ensuring stable yarn output and improving the reliability and efficiency of unwinding.

Abstract
The utility model discloses a spinning yarn coil pay-off device which comprises a platen, seat plates are installed on the platen at intervals, a shaft rod is vertically connected to the seat plates, a pressing tile is arranged on one side of the shaft rod, lugs are arranged on the outer curved surface of the pressing tile at intervals, a boosting mechanism is arranged between the upper lug and a vertical plate, and a thrust mechanism is arranged between the lower lug and the vertical plate. The outer side of the vertical plate is connected with a cylinder. A telescopic rod of the cylinder is connected with a thrust mechanism. The device is simple in structure, reasonable in design and novel and unique in thought, the telescopic rod of the air cylinder stretches out and retracts back, the lower spring drives the pressing tile to be close to or away from the yarn roll, meanwhile, the lower spring is pressed to be shortened, the acting force of the lower spring pushes the pressing tile to be attached to the surface of the yarn roll all the time, and it is guaranteed that yarn on the yarn roll does not fall off in the thread releasing process under traction force. Therefore, the yarn roll is prevented from freely rotating to be unwound, and the yarn roll is prevented from being knotted due to free unwinding under the action of traction inertia.
