Description

Technical Field

[0001] The utility model relates to the technical field of blades, in particular to an automatic feeder for blade sharpening. Background Art

[0002] The blade refers to the unhandled blade part, or the thin steel sheet installed in the safety knife holder for shaving, or the blade-shaped blade installed on the machine for cutting. When the blade is calcined, the iron or steel on the surface will oxidize or have a high carbon content and become brittle. The so-called sharpening is to grind away these at the edge of the blade to expose the steel part, so that it will be sharper. There are two ways to sharpen the blade: manual and machine sharpening.

[0003] Before sharpening the blade, the feeder's material transfer seat needs to feed the blade to the sharpening device, and then the clamping structure clamps the blade to feed the sharpening device.

[0004] For example, an arc-shaped blade punching automatic feeding device with announcement number CN211588309U and announcement date 2020.09.29 includes a base and a shell, a bracket is fixedly provided inside the base, an electric screw is fixedly provided on the top of the bracket, a bearing is fixedly provided on the inner wall of one end of the base through an axle seat, the bearing is rotatably connected to one end of the electric screw, sliding rods are fixedly provided on both sides of the top of the base, and the two sliding rods are slidably connected to the two sides of the bottom end of the shell through sliding grooves.

[0005] As mentioned above and in the prior art, when feeding the blade, the blade is usually fed through a material transfer seat. However, since the blade is relatively thin, when the material transfer seat sends the blade to the feeding position, the clamping structure is not easy to clamp the blade for feeding. Therefore, it is urgent to design an automatic feeder for blade sharpening to solve the above problem. Utility Model Content

[0006] The utility model aims to provide an automatic feeder for blade sharpening to solve the above-mentioned shortcomings in the prior art.

A lifting screw is rotatably connected to the inner wall of the rotating seat through a bearing, and the lifting plate is threadedly sleeved on the outside of the lifting screw.

[0012] Furthermore, a limit rod is arranged on the inner wall of the rotating seat, and the lifting plate is slidably sleeved on the outside of the limit rod, and a gear ring is arranged at the bottom end of the lifting screw.
