[0023] Figure 3 This is a top view of a wire-paying device that automatically adjusts wire-paying tension according to this embodiment. DETAILED DESCRIPTION

[0024] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example

[0026] like Figure 1 As shown, a pay-off device for automatically adjusting pay-off tension in this embodiment includes a bracket 1, a rotating shaft 2 and a tension adjustment mechanism;

[0027] A workbench 3 is horizontally fixed on the top of the bracket 1; the rotating shaft 2 is rotatably arranged on the workbench 3, and the rotating shaft 2 always remains in a vertical state.

[0028] like Figure 2As shown, the tension adjustment mechanism includes a fixed seat 4, a rotating seat 5 and a brake belt 6; the fixed seat 4 is fixed on the workbench 3; the rotating seat 5 is rotatably set on the workbench 3; the fixed seat 4 and the rotating seat 5 are vertically fixed with connecting columns 7, and the two ends of the brake belt 6 are respectively connected to the two connecting columns 7, and the brake belt 7 is in contact with the bottom side of the I-shaped wheel to be released.

[0029] A support beam 8 is horizontally fixed on the rotating seat 5, and a first guide wheel 9 is provided on the support beam 8; a connecting rod 10 is horizontally provided on the workbench 3, and a support rod 11 is vertically fixed on the rotating seat 5, and a spring 12 is provided between the connecting rod 10 and the support rod 11, and one end of the spring 12 is connected to the connecting rod 10, and the other end is connected to the support rod 11.

[0030] In this embodiment, a limiting plug-in 13 is inserted into the top of the rotating shaft 2 to effectively prevent the spool from shaking after being sleeved on the rotating shaft 2, thereby ensuring stable wire pay-off.

[0031] In this embodiment, the pay-off device for automatically adjusting the pay-off tension also includes a guide mechanism, which includes a support seat 14, a first guide wheel 15 and a plurality of second guide wheels 16; the support seat 14 is fixed to the workbench 3 by bolts; the first guide wheel 15 is rotatably set on the support seat 14, and its axis always remains vertical; a vertical plate 17 is fixed on the support seat 14, and a plurality of second guide wheels 16 are rotatably set on the vertical plate 17 facing the side of the first guide wheel 15, and the axis of the second guide wheel 17 always remains horizontal, so as to facilitate guiding the steel cord to the designated work station.

[0032] Furthermore, if Figure 3 As shown, the bottom of the support seat 14 is provided with a plurality of first waist-shaped through holes 18, and the bolts pass through the first waist-shaped through holes 18. Such a setting facilitates the adjustment of the position of the support seat and better guides the steel cord.

[0033] When paying out the steel cord, the spool to be paid out is sleeved on the rotating shaft 2, and the limit plug-in 13 is inserted on the top of the rotating shaft 2, and the brake belt 6 is connected to the two connecting columns 7, and the brake belt 6 is made to contact the bottom side of the spool; then the wire is paid out. During the wire paying out process, if the speed of the passive wire paying out of the spool is too slow, the rotating seat 5 is driven to rotate counterclockwise. At this time, the brake belt 6 will be loosened a little, reducing the friction with the spool, so that the rotation speed of the spool is accelerated, and the spring 12 maintains the elastic force, so that the rotating seat 5 is stable, and then the wire is transmitted to the designated workstation under the guidance of the guide mechanism.
