What Is The Reason That The Presser Does Not Return

- Sep 09, 2018 -

What is the reason why the pressure plate of the paper cutter does not return?


1. Electrical failure, in the paper cutting machine transmission mechanism (turbine box, gear transmission, etc.) will usually be equipped with 2-3 stroke switches, one is mainly used for cutting knife too low, hands away from the button, the knife will automatically return to the high point (both for cutting knife counting function); another is used for the high point stop model, when this stroke switch. If the contact position is not correct, the cutter will not stop at the high point (in this case, the fault can be relieved by adjusting the contact or stroke switch position only.




Importance of accuracy of paper cutter




2. Brake fault, in the knife drive (turbine box, gear transmission, etc.) input, must be equipped with a brake device, when the brake pad wear or excessive clearance will cause cutting knife can not stop at a high point (adjust clearance or replace the brake pad can be solved), or clutch disc has a stuck, causing inflexible return (open the brake part) Parts, cleaned and refueling can be solved.


3. Hydraulic trouble, when the new machine is manufactured, 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 runs in, resulting in the position of the paperpress is too high (generally considered that the blade is lower than the bottom of the paperpress). This simple method is that most manufacturers will set a top cover at the head of the piston. They can only be solved by thickening the top cover. The approximate parameter is 1mm when the top cover is thickened, and the paper press is reduced by about 1.4mm.
