Method for improving isometric property of sand surface of sand planting process and sand planting method

Abstract

The invention relates to a method for improving the isometric property of a sand surface of a sand planting process. The method comprises the following steps of controlling stacked abrasive materials to quantitatively fall onto a sand conveying belt through a sand discharging opening of a sand box by utilizing gravity; configuring the sand conveying belt to slightly vibrate in order to enable stacked abrasive particles to be kept at the same height on the sand conveying belt; and configuring the walking direction of the sand conveying belt and the walking direction of the base material to be intersected and positioned on different planes in order to plant the stacked abrasive particles on the primer layer of a base material at equal height through a binder. The invention further relates to a sand planting method. The sand surface of abrasive cloth prepared by the method for improving the isometric property of the sand surface provided by the invention is smooth and free of abrasive bulges, and the better isometric property is kept.

Description

technical field [0001] The invention relates to the technical field of accumulated abrasive emery cloth, in particular to a method and a sand planting method for improving the contour of a sand surface in a sand planting process. Background technique [0002] Abrasive accumulation is a group of abrasive particles with uniform particle size bonded together by a binder and uniform organization. The coated abrasive made of abrasive abrasive as a grinding material is called accumulation abrasive emery cloth. Later converted to a stacked abrasive cloth. During the grinding process, the blunt abrasive grains will continue to fall off, exposing new abrasive grains, and the service life is more than 5 times that of ordinary emery cloths with the same grain size. It is mainly used in the field of polishing. When polishing, it is necessary to ensure that the sand surface of the accumulated abrasive cloth is of equal height, so as to improve the service life of the abrasive cloth and ...

AI Technical Summary

Problems solved by technology

[0003] However, in the manufacture of accumulated abrasive abrasive cloth, the gravity sand planting process is often used, and after the sand planting is completed, friction and cutting are used to ensure the contour of the sand surface. This method will reduce the service life of the abrasive cloth or introduce impurities to pollute the workpiece; There is also a slip equal-pressure leveling machine used to evenly spread the accumulated abrasives on the surface of the substrate. This method cannot completely guarantee the equal height of the sand surface, and a small amount of protruding particles will appear on the sand surface.
