As shown in fig. 1-2, the trimming and trimming wire detecting device comprises a mounting seat 9, wherein a plurality of mounting holes 4 are formed in the lower part of the front end of the mounting seat 9 and are used for placing the detecting device on a plate and strip production line; the top and the rear end of the mounting seat 9 are respectively provided with a rotary sleeve 3 and an inductive switch bracket 7, a rotary shaft 2 is movably arranged in the rotary sleeve 3, the rotary shaft 2 can freely rotate in the rotary sleeve 3, and both ends of the rotary shaft 2 extend out of the rotary sleeve 3; the front end of the rotating shaft 2 is provided with a detection baffle plate 1, the detection baffle plate 1 is a rectangular steel plate, and the top end surface of the detection baffle plate is welded and fixed with the rotating shaft 2; the rear end of the rotating shaft 2 is provided with a strip-shaped induction iron 6, and a baffle ring 5 for limiting is also arranged on the rotating shaft 2 between the induction iron 6 and the rotating sleeve 3; the induction switch bracket 7 is provided with an induction switch 8, and the induction iron 6 corresponds to the induction switch 8; the induction switch 8 is connected with a PLC controller 10, the PLC controller 10 can be a PLC controller on a production line, the induction switch 8 is connected with and transmits signals through a data line, the PLC controller 10 is connected with an alarm device 11, and the alarm device 11 can be set as an audible-visual alarm.

When the edge trimming shear running edge wire detection device is applied, the bolts are used for mounting the edge trimming shear running edge wire detection device at the inlet of the outlet chute of the edge trimming shear head of the strip production line through the mounting holes 4 on the mounting base 9, the number of the detection devices is determined according to the implementation condition, the detection baffle plate 1 of the detection device naturally sags under the action of gravity, the induction iron 6 at the other end of the rotating shaft 2 is detected by the induction switch 8, normal operation signals are sent out to the PLC controller 10, when the edge wire runs out from the edge trimming shear head, the edge wire bumps into the detection baffle plate 1, the detection baffle plate 1 can rotate along the axis direction of the rotating sleeve 3 by an angle, meanwhile, the induction iron 6 at the other end of the rotating shaft 2 is driven to rotate together, at the moment, the induction iron 6 leaves the induction iron area of the induction switch 8, the edge wire abnormal signals are sent out to the PLC controller 10 immediately, the automatic quick stop of the control outlet area is controlled, audible and visual alarm is sent out, operators are reminded of timely treatment, and meanwhile, whether the production line is stopped according to the condition control by the PLC controller 10. Because the edge-cutting scissors are provided with four cutter heads, only two cutter heads are used for edge-cutting operation, and the other two cutter heads can be used as spare or for maintenance of the cutting edge; when the strip steel does not need to be trimmed, the trimming shears are in an off-line position.
