　　 An automatic point counting machine for FPC reinforcing steel sheet, comprising working platform 1, control panel, PLC control cabinet, discharging roller 2, front adjustable tensioning roller 3, limiting roller 4, front infrared sensing device 5, rear Infrared sensing device 6, rear adjustable tension roller 7 and receiving roller 8, discharge roller 2, front adjustable tension roller 3 are disposed outside the feeding of the working platform 1, rear adjustable tension roller 7 and receiving material The roller 8 is disposed on the receiving side of the working platform 1, and a control panel is disposed on the front side of the working platform 1, and a limit roller 4, a front infrared sensing device 5 and a rear infrared sensing device 6 are disposed above the surface of the working platform 1, and the limit is The surface of the roller 4 and the working platform 1 is left with a gap for passing the FPC-reinforced steel sheet after unwinding, and the front infrared sensing device 5 projects from one side of the working platform 1 to the middle of the working platform 1 to complete the first volume. The FPC reinforced steel sheet is counted, and the rear infrared ray sensing device 6 projects from the other side of the work platform 1 to the middle portion of the work platform 1 to complete the counting of the second roll of FPC reinforcing steel sheets, the front infrared ray sensing device 5 and the rear infrared ray. Inductive device 6 staggered before and after; front infrared sensing device 5 and rear infrared Sensing means 6 is provided with a corresponding diffuse reflection layer 9 on a working platform in the sense region. The front infrared sensing device 5 and the rear infrared sensing device 6 respectively count two rolls of FPC reinforcing steel sheets, thereby improving the efficiency of counting. The control panel is provided with a control switch and a display screen, and the PLC control cabinet includes a circuit board and a solenoid valve. The diffuse reflection layer 9 is directly adhered to the surface of the working platform 1 by using adhesive tape in practice, so as to avoid false counting caused by the reflective surface of the metal surface of the working platform 1, and the infrared sensing device emits light, and when the FPC reinforced steel sheet passes, due to the metal surface thereof The reflection reflects the light into the infrared sensing device and then counts. The material of the FPC-reinforced steel sheet is transparent and transparent.
　　 Wherein, the front adjustable tensioning roller 3 and the rear adjustable tensioning roller 7 are provided with a soft limiting ring 10 for restricting the FPC reinforcing steel sheet roll from swinging left and right during the process. The soft limit ring 10 is made of soft plastic.
　　 A metal sizing hose 11 is further mounted on the work platform 1, and an illuminating lamp 12 is provided at the front end of the metal sizing hose 11. It is convenient for employees to work at night, the headlights of the factory can be turned off, and the lighting 12 can be turned on to operate, saving electricity. The metal sizing hose 11 can arbitrarily adjust the placement of the illuminating lamp 12 for ease of use.
　　 Wherein, the discharging roller 2 and the receiving roller 8 are respectively provided with a tray 13 , and the bottom surface of the tray 13 is provided with a base 14 , and the base 14 is sleeved on the discharging roller 2 or the receiving roller 8 and passes through the base The locking member 15 of the 14 is fixed at the position of the base 14, and a T-shaped sleeve 16 is further disposed on the discharging roller 2 and the receiving roller 8, and the T-shaped sleeve 16 and the tray 13 together reinforce the entire roll of FPC.
