the third driving device is connected with a cutter and drives the cutter to do reciprocating motion to push the magnetic sheet positioned at the position of the limiting block, and the control center sends an instruction to the third driving device to enable the cutter to push the magnetic sheet to move forwards after the feeding conveyor belt stops;
the fourth driving device is connected with a sliding block and drives the sliding block to do reciprocating motion, the sliding block is arranged above the second plate body, and the motion direction of the sliding block is vertical to the longitudinal axis direction of the magnetic sheet;
the fourth detection switch is arranged above the first plate body and is opposite to the sliding block, when the cutter pushes the magnetic sheet to move to the position of the sliding block, the fourth detection switch detects the magnetic sheet and feeds detection information back to the control center, the control center sends an instruction to the third driving device, and the cutter stops pushing and returns; and meanwhile, the control center sends an instruction to the fourth driving device, so that the magnetic sheet is pushed to the inlet of the through gauge channel by the sliding block.
6. A magnetic sheet automatic pass gauge apparatus according to any of claims 1 to 5, wherein the first, second, third and fourth drive means are air cylinders.
7. An automatic gauge apparatus for the passage of magnetic flakes according to claim 5, wherein the thickness of the cutter is less than the thickness of the magnetic flakes to be inspected by more than 0.2 mm.
8. An automatic gauge apparatus for the passage of magnetic sheets according to claim 1, wherein an inlet is provided at the inlet of the gauge passage.
9. An automatic magnetic sheet passing gauge device according to claim 5, wherein limit baffles are provided on both sides of the feeding conveyor belt to ensure that the magnetic sheets to be inspected are stacked in order during the operation of the feeding conveyor belt, wherein the distance between the two limit baffles is 1mm to 3mm longer than the length of the magnetic sheets.
10. A magnetic sheet automatic gauge apparatus according to claim 1, wherein the magnetic sheet to be inspected is less than 20mm thick.
