[0016] Example 1

[0017] As Figs. 1-3As shown, a tensioner for a two-for-one twisting machine includes a tray 1, which is a circular disk made of wood or PVC, with a diameter larger than the inner diameter of a yarn bobbin 10. A circular hole is provided in the center of the tray 1, and a spindle 2 is inserted through the circular hole above the tray 1. A cavity is provided in the spindle 2, and a tensioning mechanism is provided in the cavity. The outer shell is provided on the outer shell of the spindle 2, and the outer shell is clamped or screwed to the spindle. The upper part of the spindle 2 is threadedly connected to a connector 3, and a porcelain eye 4 is provided at the head end of the connector 3. The lower part of the spindle 2 is threadedly connected to a connecting pipe 5, which passes through the tray 1 and is threadedly connected to a tension pipe 6 at the bottom end. A porcelain eye 7 is provided at the bottom end of the tension pipe 6 and is connected to a twisting disk 8. A coaxial yarn channel 9 is provided in the center of the connector 3, the spindle 2, the connecting pipe 5 and the tension pipe 6. After placing the tray 1 above the unwinding yarn bobbin 10, the tension tube 6 is inserted into the yarn bobbin 10, and the yarn unwound from the yarn bobbin 10 passes through the porcelain eye 4 into the connector 3, passes through the spindle 2, the connecting tube 5 and the tension tube 6, and is introduced into the twisting disk 8, and then is led out through the twisting disk 8 to the yarn guide rod 11 and enters the doubling machine, which can effectively keep the balloon stable and avoid the uneven tension of the balloon caused by unwinding, resulting in yarn breakage.

The tension rod 12 is made of stainless steel with a surface roughness of no more than 0.05 μm and a diameter of 0.8-1 cm to avoid excessive friction with the yarn. A movable sleeve is provided on the tension rod 12 with a pressure plate 13 and a pressure plate 2 14. The pressure plate 13 and the pressure plate 2 14 are made of rubber or ceramic, and have the advantages of light weight and low friction; there is a gap between the pressure plate 13 and the pressure plate 2 14 corresponding to the yarn channel 9, and the back of the pressure plate 2 14 is fixedly connected to the baffle 15, and the back of the baffle 15 is connected to the spindle 2 with screws. The back of the pressure plate 13 is fixedly connected to the spring 16, and the spring 16 is sleeved on the tension rod 12. The other end of the spring 16 is fixedly connected to the pressure regulating column 17, and the pressure regulating column 17 is threadedly connected to the spindle 2 and the head end extends out of the spindle 2. By rotating the pressure regulating column 17 forward or backward, the gap between the pressing plate 13 and the pressing plate 2 14 can be adjusted, that is, the clamping force on the yarn can be adjusted, which is beneficial to keep the yarn taut and consistent during the downward movement.

[0019] In order to further tighten the yarn and ensure that the tension of the yarn entering the twisting disk 8 is balanced and consistent, a plurality of thread heads 18 are stacked in sequence in the tension tube 6, and a yarn threading hole 19 is provided in the center of the plurality of thread heads 18. A telescopic bullet head 20 is provided between the first thread head 18 and the second thread head 18 in the upper part of the tension tube 6. The upper part of the second thread head is provided with a groove and a steel ball 21 is rollingly connected in the groove. The telescopic bullet head 20 includes a elastically connected telescopic small head and a telescopic large head. The ends of the telescopic large head and the telescopic small head are circular, and the outer diameter of the telescopic small head is smaller than the outer diameter of the telescopic large head. The telescopic large head is rollingly connected to the steel ball 21.

[0020] Further, the spacer 22 is arranged between the spindle 2 and the connecting head 3, which enhances the connecting stability of the connecting head 3 and avoids the connecting head 3 from loosening due to the yarn jumping.
