Description

Technical Field

[0001] The utility model relates to the technical field of drill grinders, in particular to a drill grinder with a waste cleaning function. Background Art

[0002] The drill grinder is a small tool grinder used for industrial drill bit grinding. Due to its different functions, it can grind the front angle, positive front angle, top angle, back angle, and side edge of various common twist drills, thin plate drills, step drills, etc., so as to achieve the purpose of repairing the drill bit as good as new.

[0003] In the actual process of some drill grinding machines, the grinding wheel will produce metal debris when grinding the drill bit. Since the material used for the drill bit is relatively hard, some metal debris from the drill bit will remain on the surface of the grinding wheel during grinding, which will affect the friction of the grinding wheel surface. After long-term use, the metal debris will accumulate in the space where the grinding wheel is located. Due to the small space, it is not convenient for the staff to clean it.

[0004] For example, a drill grinder with a waste cleaning function disclosed in Chinese patent CN216883003U has a brush that not only cleans the grinding wheel surface, but also cleans the inner wall of the chip groove, thereby ensuring the cleanliness of the grinding wheel surface and accelerating the speed at which metal debris enters the chip groove, so that the metal debris enters the chip groove completely. The operator can rotate the bottom plate along the rotating shaft to adjust the contact angle between the drill bit and the grinding wheel surface, thereby achieving more effective drill grinding.

[0005] However, when the device is in use, metal debris will adhere to the brush, and the metal debris in the brush cannot be cleaned, resulting in contact between the brush and the grinding wheel, which will cause the metal debris in the brush to adhere to the grinding wheel again, resulting in a poor cleaning effect.

[0006] For this reason, we urgently need to provide a drill grinder with a waste removal function. Utility Model Content

[0007] The purpose of the utility model is to provide a drill grinder with a waste cleaning function to solve the problem proposed in the above background technology that metal debris will adhere to the brush during use, and the metal debris in the brush cannot be cleaned, resulting in the brush contacting the grinding wheel, causing the metal debris in the brush to adhere to the grinding wheel again, resulting in poor cleaning effect.

[0012] Preferably, the cleaning unit is located inside the beating unit, and the brush roller is in contact with the surface of the grinding wheel. The brush roller rotates and contacts the grinding wheel, thereby sweeping away metal debris on the surface of the grinding wheel.

[0013] Preferably, the rotation direction of the two left and right brush rollers is the same as that of the grinding wheel, and the rotation speed of the brush rollers is lower than that of the grinding wheel, so that the brush rollers can sweep away metal debris on the surface of the grinding wheel.

[0014] Preferably, the clapper is in contact with the brush roller, and the clapper rotates in the opposite direction to the brush roller. The two clappers are driven to rotate by motor 2, so that the clappers can discharge metal debris attached to the brush roller, thereby facilitating the cleaning of the brush roller.

[0015] Preferably, a rectangular groove of the same size as the waste box is opened on the right side of the shell, and the waste box is slidably connected to the inside of the shell, so that metal waste generated during grinding can be collected through the waste box.
