Design and installation principles of paper cutting machine blades

1. The shape design of the paper cutting machine blade should be simple and reasonable, because the structure is simple, which is convenient for the design of the cutting machine, inspection, maintenance, and troubleshooting of the machine. This is because the dead corners and gaps of the speed tube are easy to collect paper pieces, thereby blocking the machine.

2. In order to avoid the risk of stress corrosion cracking of the blade in the design of the paper cutter, stress concentration should be avoided as far as possible to reduce or eliminate residual stress.

In order to prevent electrode corrosion of the lined pipeline, a series of measures need to be taken: avoiding different metal contact, forming electrolytes on the surface of the pipeline, and preventing the pipeline from coming into contact with easily absorbent materials. Paper cutting machine

4. Try to avoid crevice corrosion at the blade secondary interface to prevent crevice corrosion. In the blade gap junction, the method of butt welding and continuous welding shall be adopted, and solid, elastic, waterless sealing gasket and other materials shall be selected at the gap joint to avoid the gap of the lined pipe.

5. Prevent blade corrosion caused by potential differences caused by temperature differences, ventilation differences, solution concentration differences, etc.

6. In the installation environment of Paper Cuttings machine, the place with less natural corrosion shall be selected, such as avoiding accelerated corrosion of marine atmosphere, industrial sewage, chemical plant smoke, etc.
