Description

Coffee grinds beans machine with adjustable stop nut subassembly and coffee grinds beans machine

Technical Field

The utility model relates to a coffee grinds technical field, in particular to coffee grinds beans machine with adjustable stop nut subassembly and coffee and grinds beans machine.

Background

The coffee bean grinder finishes coffee bean grinding by mutually extruding and cutting the inner cutter disc and the outer cutter disc, and the grinding thickness of the coffee beans depends on the distance between the inner cutter disc and the outer cutter disc. The traditional coffee bean grinder with the center shaft adopts the structure that a bearing, an adjusting spring, an outer cutter head, an inner cutter head, a limiting sheet and an adjusting nut are arranged on the center shaft. The bean grinding machine is characterized in that a rectangular limit is arranged at the tail end of the middle shaft, a square limit hole is formed in the joint of the limit piece and the mounting shaft, the mounting shaft rotates to drive the limit piece to rotate, the limit piece drives the inner cutter disc to rotate, the outer cutter disc is fixed and does not rotate, and accordingly the inner cutter disc and the outer cutter disc rotate to grind beans. The adjustment of the thickness of the ground beans depends on the distance between the inner cutterhead and the outer cutterhead, the outer cutterhead is fixed, the inner cutterhead can move up and down along the middle shaft under the action of the adjusting spring and the adjusting nut, namely, the inner cutterhead is far away from or close to the outer cutterhead to move, the distance between the inner cutterhead and the outer cutterhead is changed, and therefore the grinding degree of the thickness of the ground beans is changed. By adopting the adjusting mode, once the bean grinder is disassembled and cleaned, the adjusting nut needs to be screwed to the bottom for resetting and correcting when the bean grinder is installed, then the grinding roughness used at each time is combined, the grid is reversed and adjusted to be fixed, and the whole process is very complicated.
