Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a grinder which is convenient for disassembling, assembling and replacing a grinding roller. Background Art

[0002] Roller grinder is a kind of equipment used to grind and polish the surface of an object. Roller grinder grinds by applying pressure and friction when the rotating roller contacts the surface of the object. Roller grinder grinds the material with the grinding roller, but the grinding roller will be worn out after long-term use, and it is inconvenient to disassemble and replace the grinding roller.

[0003] A Chinese patent discloses a suspended roller press roller surface grinder (authorization announcement number CN211388025U), which mainly includes a roller press body, a composite roller, a cross bar, a grinding machine body, a reducer and a motor. A rotating shaft is rotatably installed inside the roller press body, and the composite roller is mounted on the rotating shaft. Fixed plates are fixed on both sides of the front of the roller press body, and connecting rods are fixed on the front of the fixed plates. The front ends of the two connecting rods are respectively fixedly connected to the two ends of the cross bar, and tracks are fixed on the upper and lower end surfaces of the cross bar. U-shaped plates are fixed at the front ends of the brackets on both sides of the grinding machine body, and sliders are fixed on the upper and lower ends of the inner wall of the U-shaped plate. The U-shaped plate is clamped on the cross bar, and the sliders at the upper and lower ends of the inner wall of the U-shaped plate are respectively slidably connected to the tracks on the upper and lower end surfaces of the cross bar, and a counterweight is fixed at the front end of the grinding machine body.

[0004] However, there are still some shortcomings in this patent. This patent has the advantages that the grinding force is controlled by the counterweight, the grinding speed is faster, and the damage to the human body caused by metal debris is effectively reduced; however, the roller grinder grinds the material through the grinding roller, but the grinding roller will be worn out after long-term use, and it is inconvenient to disassemble and replace the grinding roller. Therefore, those skilled in the art provide a grinder that is easy to disassemble and replace the grinding roller to solve the problems raised in the above background technology.
