Case analysis of paper cutter cutting deviation
- Aug 08, 2018 -

When customers choose our paper cutting knife, they may meet different situation but not caused by our paper cutting knife. Then you need to know what cause the situation.

 

In terms of paper cutting machine equipment, we may sometimes find that the paper they cut has some slant marks, and the product does not meet their production standards, so what exactly caused this?


It is found that in the paper cutting machine, the adhesive layer viscosity of the non-drying adhesive is relatively strong, so the resistance value to be overcome in the cutting process of the undercutter is relatively large, and in the moment of its cutting, the paper presser will have a slight upward movement, which will cause the slanting phenomenon of its cutting. This phenomenon was further analyzed. After a series of tests on the operating pressure of its paper press machine, solenoid valve, the purity of its circulating lubricating oil, hydraulic system, etc., it was found that there would be a certain gap between the operating pressure of its paper press oil cylinder and the technical requirements of the machine. Then we can be in view of the oil cylinder pressure paper apart, found that the pressure in the cylinder spring has broken into two pieces, the elastic pressure value will also corresponding occurrence is reduced, and when we replace the spring, after the oil cylinder pressure paper work pressure value and will return to its normal state, and the cutter cut out paper also have no the phenomenon of tilt.


In fact, after being used for a period of time, the tension spring in the paper cutter will appear fatigue cracking phenomenon, and the pressure value in the paper cylinder will be correspondingly reduced, which has no effect on its paper cutting principles. And only when its adhesive viscosity is also relatively large, as a result of its action resistance value increase, will appear the corresponding cutting deviation phenomenon.
