Copper strip striping device with speed self-adaptation function

The invention discloses a copper strip striping device with the speed self-adaptation function. The copper strip striping device comprises an unwinding machine, a striping mechanism and a winding machine. An unwinding pit is arranged between the unwinding machine and the striping mechanism, and a winding pit is arranged between the striping mechanism and the winding machine; and the device further comprises a speed adjuster for adjusting the unwinding speed of the unwinding machine and a set of photoelectric sensors for detecting the position of a copper strip. The photoelectric sensors are arranged on the pit wall of the unwinding pit in a different-height-position manner and are connected with the speed adjuster; the photoelectric sensors are utilized for measuring the height and the distance of the copper strip, and therefore the unwinding speed of the unwinding machine is adjusted through the speed adjuster, and following connection variable control over the strip speed can be achieved; and bottoming or stretching scraping of the copper strip can be avoided, a worker can simply and conveniently carry out operation, and equipment running is efficient.
