DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0016] Please refer to Figures 1-3 , a circular knife sharpening machine, including a circular knife disc 1, the circular knife disc 1 is fixedly installed on a mounting seat 2, the mounting seat 2 can drive the circular knife disc 1 to move, the mounting seat 2 is fixedly installed on a workbench, one side of the circular knife disc 1 is provided with a wide opening and a small blade adjacent to the wide opening, the small blade is the blade edge of the knife, a small blade grinding disc 4 for grinding the small blade, a wide opening grinding disc 3 for grinding the wide opening and a deburring grinding disc 5 are installed on the workbench, the three are adjustable in angle relative to the circular knife disc 1, the deburring grinding disc 5 is located on the other side of the small blade, the small blade grinding disc 4 is grinding the blade edge of the circular knife disc 1, but during grinding, burrs and protrusions will be generated on the other side of the blade edge, and the deburring grinding disc 5 can grind the burrs and protrusions, so that the circular knife disc 1 can cut materials more smoothly.
[0017] The small blade grinding disc 4, the deburring grinding disc 5 and the wide opening grinding disc 3 are all structures in which the grinding discs are hinged to the brackets and have a locking function. By adjusting the angles of the grinding discs, the angles of the wide opening and the small blade on the circular knife disc 1 can be controlled.
[0018] The mounting base 2 includes a lateral movement module 21 for controlling the lateral movement of the circular cutter disc 1 and a longitudinal movement module 22 for controlling the longitudinal movement of the circular cutter disc 1.
