The clamping unit comprises a mounting seat, a rotating shaft and a motor, the grinding unit comprises a communication column and an adjusting mechanism, a first piston is slidably connected in one sideof the communication column, a first plunger piston is rotatably connected on the first piston, a second piston is slidably connected in the other side of the communication column, a second plunger piston is rotatably connected on the second piston, grinding wheels are fixed onto the first plunger piston and the second plunger piston, a first gear cylinder is fixed onto the first plunger piston,a first gear is fixed onto the second plunger piston, the transmission unit comprises a transmission shaft rotatably connected on the frame, an output gear and a second gear cylinder are fixed onto the transmission shaft, the output gear is engaged with the first gear cylinder, the second gear cylinder is engaged with the first gear, and a third gear cylinder engaged with the first gear is fixed on the rotating shaft. A circular blade is grinded by the knife grinder, knife edges of two surfaces of the circular blade can be grinded, and working efficiency is improved.

Description

technical field

[0001] The invention belongs to the technical field of knife sharpening devices, in particular to a knife sharpening machine. Background technique

[0002] The sharpening machine is used to trim the blade. Compared with the blade sharpened by hand, the use strength of the blade is increased, and the service life and processing capacity of the blade are also improved accordingly. Therefore, the sharpening machine is suitable for printing, papermaking, packaging, plastic leather, Indispensable special equipment for woodworking and other industries. After the blade has been working for a long time, the sharpness of the blade will decrease or the blade will be worn. Therefore, the blade needs to be re-grinded. Different models can be selected according to the type and size of the blade to re-grind the blade.

[0003] The round blade sharpener is a kind of sharpening machine, which is used for automatic sharpening of various round blades. The structure of the exi...
