Description

Technical Field

[0001] The invention relates to the technical field of grinding wheel production, in particular to a material spreading device and method for producing resin grinding wheels. Background Art

[0002] Resin-reinforced grinding wheels are porous bodies made by adding a resin bond and a core reinforcement ring to abrasives, then pressing, drying, and firing. They are an industrial tool that plays a vital role in metal and non-metal cutting and grinding across a wide range of fields. During the resin-reinforced grinding wheel production process, after adding powdered molding compound to a mold, the compound needs to be further flattened. A hydraulic press then applies pressure to bring the loose granular molding compound within the mold to the required density, thus forming a grinding wheel blank of standard size and shape.

[0003] Most of the existing material spreading devices used in resin grinding wheel production use scrapers to level the material. However, after leveling, the excess material will gather in front of the scraper, requiring workers to remove the excess material later, which is more troublesome. Moreover, after leveling, workers need to remove the scraper to prevent the scraper from blocking subsequent operations, which is more troublesome.

When the rotating shaft (139) moves, the scraping input rotating shaft (139) drives the first scraping rack (1317) to move, the first scraping rack (1317) drives the scraping limiting gear (1316) to rotate, the scraping limiting gear (1316) drives the second scraping rack (1320) to make the scraping limiting slide plate (1319) move along the scraping limiting chute (1318), and the scraping limiting slide plate (1319) drives the scraping pin rod (1321) away from the scraping pin hole (1323), thereby releasing the limit on the scraping plate (1322); Step 3: scrape out the excess material, start the scraping motor (131) to drive the scraping output gear (132) to rotate the scraping input gear (138), the scraping input gear (138) drives the scraping linkage shaft (137) to rotate the scraping second direction adjustment gear (1325), the scraping second direction adjustment gear (1325) drives the scraping first direction adjustment gear (1310) to rotate the scraping input shaft (139), the scraping input shaft (139) drives the scraping first bevel gear (1311) to rotate the scraping second bevel gear (1313), the scraping second bevel gear (1313) drives the scraping rotating vertical rod (1312) to rotate the scraping plate (1322), and the scraping plate (1322) rotates to scrape the excess material into the annular collection frame (5); Step 4: Pressing, starting the pressing telescopic rod (7) to drive the pressing mounting frame (8) to lower the pressing plate (9), and the pressing plate (9) descends to squeeze the material in the pressing mold (4), thereby pressing the material in the pressing mold (4) into shape; Step 5: Taking out, starting the ejection motor (121) to drive the ejection circular plate (122) to rotate, the ejection circular plate (122) drives the ejection arc lifting slope (123) to rotate, the ejection arc lifting slope (123) rotates the extrusion ejection roller (126) to make the ejection rod (125) rise, and the ejection rod (125) drives the ejection plate (124) to rise, thereby taking out the material in the pressing mold (4).
