TECHNICAL FIELD
[0001] The utility model relates to a wire pay-off machine technical field, especially a kind of automatic speed regulating device when wire is changed in wire pay-off machine. BACKGROUND
[0002] The wire pay-off machine is also called as wire pay-off machine, and the wire pay-off part is composed of two spinning barrels, and the spinning barrel in the wire pay-off part is loaded with conductor coil, and the conductor coil in the spinning barrel is wrapped with an insulating layer after passing through the extruder to form electric wire. In order to improve the efficiency, the wire pay-off machine is generally provided with one conductor coil in each of the two spinning barrels, and the conductors in the two spinning barrels are connected end to end, that is, the front end of the conductor in the spinning barrel being payed off is connected with the cable coating device, and the rear end is connected with the front end of the other spinning barrel, so that when the conductor in one spinning barrel is payed off to the end, the conductor can be replaced without stopping the machine, the front end of the other spinning barrel is automatically pulled to the cable coating device, and the complete electric wire is always maintained, and only the empty spinning barrel needs to be continuously supplemented and connected with the rear end of the conductor in the spinning barrel being payed off, so that the wire pay-off machine needs two spinning barrels to place the conductors.
[0003] Generally, the tail end of one axis conductor is welded with the head end of another axis conductor by a cold welding machine to connect them, and an opening needs to be formed in the wall of the spinning barrel for the conductor to pass through, and then the direction is switched to different spinning barrels, so that when the conductor in one axis is used up, it can be switched to another axis through the connecting opening, so that the conductor can be replaced without stopping the machine, and once the machine is stopped, not only the pay-off speed will be affected, but also the subsequent winding device and a series of subsequent processes will be stopped until the replacement of the conductor is completed, and then the subsequent process devices are started one by one, which seriously affects the operation of the equipment, and the front end cable of the equipment is wasted because the equipment has not been stabilized.
[0004] At present, the conductors placed in the spinning barrel are copper wires, and due to the limitation of welding technology and materials, the strength of the copper wire after welding is not enough, and when the wire pay-off machine is payed off at high speed, the speed can reach 1300 m / min, and when the conductors in different spinning barrels are automatically switched, the copper wire connection point is easy to be pulled off, and if the copper wire is pulled off, the wire needs to be rethreaded and the machine needs to be started again, so that the double spinning barrel loses its design significance and still causes time waste in production. At present, when the conductor in one spinning barrel is almost used up, manual measurement is used to quickly replace the axis and switch the conductor in the spinning barrel, and the speed is manually reduced to about 700 m / min, which can prevent the welding point from being pulled off, and then the wire pay-off machine is manually accelerated to the original set speed after the axis is successfully replaced.
[0005] This operation is too complicated, and personnel need to be on duty frequently, and it is also necessary to ensure that it cannot be missed, in order to avoid missing the welding point, the speed is generally reduced in advance, which not only affects the pay-off efficiency of the cable, but also increases the demand for the on-duty post, increases the complexity and uncontrollability of the production process.

[0037] Therefore, the wire passing channel in the middle of the two-layer frame plate 3 needs to be kept flat with the wire passing groove 11 and polished smooth to ensure the smoothness of the wire travel and avoid wire hanging.
[0038] Each unwinding barrel 1 is provided with a detector 12; the detector 12 is a laser displacement sensor; the detection direction of the detector 12 is directly opposite the wire roll at the rear end inside the unwinding barrel 1.
