Problems solved by technology

The coated abrasive produced by this method of planting sand inevitably has the following disadvantages: the grinding surface is an uneven surface of sand grains, and the unevenness of this surface is caused by the difference in grain size of sand grains (the grain size of sand grains is always at a certain size range)
This will cause scratches of different depths during the grinding process, which will affect the quality of the grinding, especially the deep scratches of large-sized sand particles will have a greater impact on the grinding quality; thus reducing the grinding efficiency

Abstract

The invention provides an abrasive grain dispensing device and method for a coated abrasive tool. According to the scheme, the abrasive grain dispensing device comprises a coated abrasive tool base material, an auxiliary base material, adhesive application devices, a coated base material unrolling device, an auxiliary base material unrolling device, an abrasive grain dispensing device body, a stripping device, rollers, first compression rollers, second compression rollers, a take-up device and an oven. According to the scheme, firstly, abrasive grain dispensing is carried out on the auxiliary base material, next, after smooth faces of abrasive grains get close to one side of the auxiliary base material through the compression rollers, the abrasive grains are attached to the coated abrasive tool base material, then, the stripping device is used for stripping the auxiliary base material, and therefore the smooth faces of the abrasive grains on the coated abrasive tool base material face the outside, the grinding requirement is met, and the grinding efficiency is improved.

Description

technical field [0001] The invention relates to a production device for coated abrasives, in particular to a sand planting device and method for coated abrasives. Background technique [0002] At present, there are two main methods of sand planting in the production of coated abrasives: one is gravity sand planting and the other is electrostatic sand planting, but their basic structures are similar. The coated abrasive produced by this method of planting sand inevitably has the following disadvantages: the grinding surface is an uneven surface of sand grains, and the unevenness of this surface is caused by the difference in grain size of sand grains (the grain size of sand grains is always at a certain size range). The sand with large particle size is higher, and the sand with small particle size is lower. This will cause scratches of different depths during the grinding process, which will affect the quality of the grinding, especially the deep scratches of large-sized sa...
