When cutting about 100g of coated paper, the size of the finished paper is often small on the top and large on the bottom. Careful observation will also show that the bottom paper bulges upward during the cutting process. This is not a malfunction of the machine itself, but mainly because the object to be cut is harder and the surface is smoother. When the blade angle is too small and the gap between the tool holder and the frame is slightly larger, the rigidity of the mechanical structure is not enough. All the fixing screws of the front and rear frames can be loosened, and the adjustment copper between each fixing screw can be properly removed to reduce the gap between the frame and the knife holder (normally about 0.05--0.10mm, with a small gap) , It is better to shake the knife seat up and down easily and flexibly). It can change the grinding angle of the blade, which is about 26? According to our experience, especially for users who use horizontal grinding wheels with circular arc grinding wheels, because the diameter of the new and old grinding wheels directly determines the angle of the grinding edge , So a blade with a width of about 6-7 mm can be ground at the blade front to increase the angle.
Taking into account the mechanical structure and the rigidity of the blade, now the machines of SQZK series 1150 and above have all increased the thickness of the blade to 13.7mm, and the positions of the screw holes have been staggered up and down to increase the bonding strength. I hope users pay attention to the specifications when buying the blade.
The angle of the blade is difficult for most users to accurately judge without special instruments. So I specially made a table, you can compare this table, according to the length of the blade slope to determine the approximate angle of the blade.
