The ordinary hydraulic paper cutter will not slip if the oil pipe is not leaking. There are three cases of electric:
        First, with an electromagnetic clutch, when the knife holder returns to the top, the clutch will pull in, ejecting the mechanical arm with a hook, locking the knife holder (hanging, a mechanical mechanism) to prevent the knife holder from falling off. If this is the case, check the clutch action and mechanical mechanism here to see if there is a problem.
        Second, the lower knife motor itself has a brake (brake). At the rear of the motor, this situation should be the brake (brake) is not working. Check whether the brake of the motor is defective, and then make a judgment to see if it needs to be replaced?

        Third, the mechanism without knife lock and without brake, completely rely on the photoelectric sensor or limit switch to control the position of the tool holder stop, so the stop position will not be very accurate. Once the sensor fails, either the machine will not move, or it will be The non-stop movement is quite dangerous.
