Cold heading wire tailing recycling and length monitoring device and method

The invention discloses a cold heading wire tailing recycling and length monitoring device and method. The device comprises feeding wheels, a guide pipe, a first tailing switch, a second tailing switch, a shearing mold and a main machine, wherein the guide pipe is mounted between the first tailing switch and the shearing mold; and the guide pipe is disconnected in two sets of feeding wheels. The device is characterized by further comprising a PLC; the PLC is electrically connected with the main machine; the second tailing switch is mounted between the two sets of feeding wheels; and the diameter of the guide pipe is consistent with the diameter of a wire. The device can realize continuous feeding of tailings after passing through the feeding wheels, monitors the lengths of the tailings inreal time, and prevents blockage. The device belongs to the technical field of screw forming machines. 本发明公开了一种冷镦线材尾料再利用及长度监测装置及方法，该装置包括送料轮、导料管、第一尾料开关、第二尾料开关、剪模以及主机，所述导料管安装于第一尾料开关与剪模之间，导料管在两组送料轮处断开，其特征在于，还包括PLC控制器，所述PLC控制器及主机
