Copper-clad plate sized paper sampling device

The utility model discloses a copper-clad plate sized paper sampling device and belongs to the technical field of copper-clad plate processing equipment. The technical key point is that the copper-clad plate sized paper sampling device comprises a servo motor, wherein a power output shaft of the servo motor is connected with a slicing knife, a circuit of the servo motor is connected with a programmable logic controller (PLC), and a rotary shaft of the servo motor is connected with a coding disc made of glass. Black stripes are evenly distributed on the edge of the coding disc along the circumferential direction and are used for blocking rays of light. Luminous sources and light receiving elements are arranged at two sides of the coding disc, wherein the light receiving elements are in electric connection with the PLC, and the PLC is connected with the servo motor and the light receiving elements through pulse signals. The utility model aims at providing a copper-clad plate sized paper sampling device which is compact in structure, convenient to use, and capable of greatly saving production cost. The copper-clad plate sized paper sampling device is used for sized paper sampling.
