Description

Abrasive material spreading mechanism and grinding wheel production equipment Technical Field The application relates to the field of grinding wheel production and processing, in particular to an abrasive material paving mechanism and grinding wheel production equipment. Background The grinding wheel is a common grinding device, and grid cloth is generally buried in the grinding wheel, and is mainly used for enhancing the structural strength of the grinding wheel and preventing the grinding wheel from being broken during high-speed operation. The grinding wheel body mainly comprises an abrasive material and grid cloth. Wherein the abrasive material generally comprises materials such as white corundum, phenolic resin, cryolite and the like, and the mesh cloth can be made of glass fiber materials. In the process of manufacturing the grinding wheel, the grinding wheel is obtained by alternately paving the grinding material and the mesh cloth in a mold, pressing the multi-layer structure into a whole by pressing, and then performing heat curing. After filling the abrasive into the mold, the abrasive needs to be scraped off due to the accumulation of the abrasive in a local area in the mold, and the conventional scraping method is to scrape off the abrasive by using a horizontal scraper that rotates relative to the mold. The abrasive material higher than the preset height is pulled to the gap by the gradually descending scraping plate. However, such squaring is not only inefficient, but also has limited scraping effect, and the abrasive may take a long time to move to the gap when pushed by the blade, and may not even flow to the gap. For example, when the abrasive stack is in the middle, the abrasive is far from the inner edge of the die, it is difficult or time consuming to move the ultra-high abrasive to the inner edge of the die with the push plate alone. For the above problems, some manufacturers choose to throw materials into different areas in the mold to form a plurality of piles, and then reduce the initial height of the scraping plate to perform scraping. The materials are put in different areas in the die, so that the abrasive materials can be dispersed at the beginning, the subsequent scraping is convenient, and the initial height of the scraping plate is reduced, so that the scraping plate can push more ultrahigh abrasive materials to move at the beginning. For example, by setting the initial height of the blade bottom equal to the preset height, the blade is enabled to initially push all the ultra-high abrasive to move, thereby rapidly screeding. However, feeding multiple stacks of abrasive increases the complexity of feeding, and the blade pushing more abrasive at a time may cause disturbance to the grid cloth below the abrasive. And although the above solution helps the scraping speed, it does not completely ensure that the ultra-high abrasive can be rapidly filled to the corners. Secondly, traditional strickle can only scrape away the abrasive material of windrow upper strata, and the abrasive material of windrow lower floor owing to the existence of crane span structure phenomenon, partial region probably has the phenomenon of material deficiency, and the homogeneity of abrasive material can not guarantee, influences the quality of emery wheel.
