In one embodiment, a rotating plate 8 is rotatably connected to a side wall of the sliding chute 6, the other end of the spring 7 is connected to the rotating plate 8, and the spring 7 is a torsion spring.
In one embodiment, the turntable 8 is connected with an adjusting motor 12, and the adjusting motor 12 is arranged in the side wall of the chute 6.
In one embodiment, the take-up pulley 2 is connected with a take-up motor, and the pay-off pulley 4 is connected with a pay-off motor.
In one embodiment, the take-up pulley 2 and the pay-off pulley 4 are coaxially provided with an anti-reverse gear 10, and the anti-reverse gear 10 is engaged with a ratchet wheel.
In one embodiment, the optical fiber pay-off device further comprises a guide wheel 9, wherein the guide wheel 9 is rotatably connected to the wire frame 1, and the optical fiber is paid off from the pay-off wheel 4 and then guided by the guide wheel 9.
In one embodiment, the side wall of the sliding groove 6 is provided with a limit block 11, the sliding block 5 is arranged between the two limit blocks 11, and the one end of the spring 7 passes through one of the limit blocks 11 and is connected to the sliding block 5; and a pressure sensor is arranged on one side of the limiting block 11, which faces the sliding block 5.
The invention is described below with reference to the accompanying drawings:
the optical fiber is firstly wound on the pay-off wheel 4, the pay-off motor and the take-up motor work, the optical fiber is paid off through the pay-off wheel 4, and the optical fiber sequentially passes through the guide wheel 9 and the plurality of tensioning wheels 3 and then is wound on the take-up wheel 2.
The spring 7 is configured to: the tension applied by the spring 7 to the slider 5 is equal to the force of the optical fiber on the tension wheel 3. At this time, when the tension of the optical fiber is reduced, the elastic force of the spring 7 is greater than the acting force of the optical fiber on the tension pulleys 3, so that the tension pulleys 3 move in opposite directions to elongate the optical fiber, thereby increasing the tension of the optical fiber and reducing the tension of the spring at the same time, until the acting force of the optical fiber on the tension pulleys 3 is balanced with the tension of the spring 7 on the slider again. When the acting force of the optical fiber on the tension wheel 3 is larger than the pulling force of the spring 7 on the sliding block 5, the tension wheels 3 move oppositely, the optical fiber is shortened to reduce the tension of the optical fiber, meanwhile, the spring 7 is further stretched, and the pulling force of the spring is increased until the acting force of the optical fiber on the tension wheel 3 is balanced with the pulling force of the spring 7 on the sliding block.
Because the take-up pulley 2 and the pay-off pulley 4 are connected with the anti-reverse gear 10, and the anti-reverse gear 10 is meshed with the ratchet wheel, the take-up pulley 2 and the pay-off pulley 4 can only rotate towards one direction, and therefore, when the tension pulley 3 moves, the take-up pulley 2 and the pay-off pulley 4 cannot rotate reversely.
When the slider 5 is obstructed by the limiting block 11, the pressure sensor receives a signal, and the tensioning wheel 3 is at the limiting position at the moment. When the tensioning wheel 3 is at the limit position, if the tension requirement cannot be met, the adjusting motor 12 is started, the rotary disc 8 and the torsion spring 7 are rotated, the tension of the spring 7 on the sliding block 5 is reduced or improved, and then the tension adjusting range is changed, so that the optical fiber tension capable of meeting the requirement is obtained.
In the embodiment, the tension pulley 3 is arranged, and the position of the tension pulley 3 is adjusted by utilizing the balance between the elastic force and the tension of the spring 7 when the tension of the optical fiber changes, so that the tension of the optical fiber is fed back and adjusted, the proper tension of the optical fiber is ensured, and the optical fiber cannot be loosened due to too small tension or broken due to too large tension.
