Description
Technical Field
The utility model relates to a small particle object grinding field, more specifically say, relate to a grinding structure for grinding of small particle thing body surface.
Background
A grinding structure for grinding and cleaning the surface of small particle objects (grains of seeds of grains, beans, nuts, etc. and granules of wood, plastic, mineral, metal, etc.) generally includes a housing, a driving structure, a drum, a roller, a treatment chamber (corresponding to a material guide chamber in the present invention), an inlet portion for an object to be ground, an outlet portion for the ground small particle objects, and the like; in grinding, the drive structure rotates the drum and the drum, and the small particle objects circulate along a predictable path in the processing chamber under the action of the rotation of the drum, so that the small particle objects repeatedly contact the drum to remove the outer layer of the article.
Referring to fig. 4, the prior art processing chamber has a rectangular configuration, and thus the predictable path of the small particle objects is rectangular. Because the left wall and the right wall of the rectangular structure are parallel, when the right wall is intersected with the arc surface of the roller or the abrasive belt, the right wall is intersected with the arc tangent of the roller or the abrasive belt to measure an included angle of 84 degrees. Because the angle is less than 90 degrees, small particle objects are positioned at the upper right corner of the chamber to form a larger dead angle, and because the roller or the abrasive belt rotates towards the right direction, the small particle objects are lost due to unsmooth flow, the loss is of a forward follow-up type, and the loss is not stopped as long as the roller or the abrasive belt continues to rotate towards the right direction. The intersection included angle between the left wall of the rectangular structure and the arc tangent of the roller or the abrasive belt is 84 degrees, the space in the treatment chamber is not fully utilized due to the fact that the roller or the abrasive belt rotates rightwards, waste is caused, and small particle objects can be directly guided in without passing through corners.
Referring to fig. 5, in order to solve the problem of the separation of the ground outer layer of the small particle objects from the ground small particle objects in the prior art, a channel for separating the ground outer layer of the small particle objects from the small particle objects is reserved in one of the openings of the processing chamber. In fact, because the rollers or belts are full of sand grains, and if the sand grains are triangular, the arrangement of the sand grains on the rollers or belts is a small triangle, and the sharp angles are radiated outwards, so that the reversed triangular gap figure 5 exists, and the openings are not provided. The defects of manufacturing process equipment mainly cause that the consistency of the quality of parts is difficult to control and the rotating shaft part jumps, and the opening is arranged carelessly. Higher precision should be achieved by grinding the left or right wall by itself as far as possible after assembly.
