Description

Gap adjustment grinding device

The present invention relates to a gap adjusting grinding device, in particular to a precision fine-tuning grinding machine with a gap adjusting grinding device between the grinding stone and the lower grinding stone, which can stably and accurately transmit the external thread and the internal thread. Adjusting the distance between the upper grindstone and the lower grindstone, the grinding thickness can be adjusted quickly, simply and accurately, especially the base, the lifter, the toothed disc and the rotating rod of the grinding device.

The conventional food grinder generally has an upper grindstone, a grindstone and a motor. When used, the crops such as beans, rice or sesame seeds can be poured between the upper grindstone and the lower grindstone, and then the motor is started. The upper grindstone or the lower grindstone is rotated so that the food is ground into a granular, powdery or slurry form without adding water or adding water between the upper grindstone and the lower grindstone.

In order to control the thickness of the food to be ground into a powder or a slurry, a finely adjusted structure between the grindstone and the undergrinding stone on the conventional food grinder is usually provided around the grindstone or the undergrinding stone. There are a large number of bolts and screw holes, so that between the upper grindstone and the lower grindstone, a plurality of bolts and screw holes around the screw are mutually screwed; if the distance between the upper grindstone and the lower grindstone is to be adjusted, the difference can be adjusted separately. The position of the set of bolts and screw holes of each group is used to adjust the rise and fall of the upper grindstone (or the lower grindstone), thereby adjusting the thickness of the grinder.

However, the disadvantage is that it is difficult to adjust the position of the screw group of each set of bolts and screw holes in a uniform manner by adjusting a plurality of array bolts and screw holes around the upper grindstone and the lower grindstone, that is, it is difficult to accurately adjust the upper grindstone at the same time. The spacing between the two sides of the lower grinding stone is prone to different positions of the bolt groups of the bolts and the screw holes. For example, the position of the bolt group on the side of the upper grindstone and the lower grindstone is higher, and the upper grindstone and the lower part The position of the bolt group on the other side of the grindstone is low, which may cause the error and skew of the height of the upper grindstone and the lower grindstone, affecting the grinding quality of the food, and the multi-array bolt and the screw hole must be one by one. Constantly adjusting to reduce the error and skew on both sides of the upper grindstone and the lower grindstone, and the operation and adjustment are time-consuming and inconvenient to use.
