Origami, what is the reason why you like to take two pictures? Please master the answer, thank you.

First of all, distinguish whether the folding machine you use is a grinder or a water pump.

The paper pick-up wheel itself is prone to double sheets, and the solution is: fully loosen the paper before putting it; Put less paper and put it frequently; Reduce the pressure of the friction wheel; Replace the new friction wheel and rubber pad.

The suction folding machine produces double sheets, mainly because the suction adjustment is not good. Solution: fully loosen the paper before putting it; Reduce the blowing properly, but ensure that 8~ 10 faces are blown open; Reduce the suction appropriately; Appropriately increase the distance between the paper pile surface and the suction nozzle or wheel; Appropriately increase the detection distance of isolation paper, etc.
