What is the reason why the pressure plate of the paper cutter does not return to position:
        1. Electrical failure, 2 ~ 3 stroke switches are usually arranged behind the cutter drive mechanism (turbine box, gear transmission, etc.), one is mainly used after the cutter is too low, when the hands leave the button, the cutter will Automatically return to the high point (considering the function of cutter counting); the other one is used to stop the high point. When the position of the travel switch and the bumper is not correct, the cutter will not stop at the high point Need to adjust the position of the bumper or the travel switch to remove the fault.
        2. Brake failure, there must be a brake device on the input end of the cutter transmission device (turbine box, gear transmission, etc.). When the brake pad is worn or the gap is too large, the cutter cannot stop at a high point (adjust the gap or replace the brake pad) It can be solved), or the clutch disc is stuck, which makes the return position inflexible (disassemble the parts of the brake, clean and add oil to solve).

        3. Hydraulic failure, when the new machine leaves the factory, the hydraulic piston does not return to the low point. After a period of use, the piston returns to the low point after the surface is worn in, causing the position of the paper press to be too high (generally the blade is lower than the bottom of the paper press ), This simple method of processing is that most manufacturers will set a top cover on the piston head, we only need to thicken the top cover to solve. The approximate parameter is that when the top cover is thickened by 1mm, the paper presser is lowered by about 1.4mm.
