Grinding wheel preparation and spreading device capable of absorbing sand

Abstract

The invention discloses a grinding wheel manufacturing spreading device with a sand sucking function. The grinding wheel manufacturing spreading device comprises a support frame. A conveying belt is arranged on the support frame, a plurality of die cavities are arranged in the conveying belt, and a feeding mechanism, a spreading mechanism, an excess material sucking mechanism and a rotating mechanism are further arranged on the support frame. The grinding wheel manufacturing spreading device has the advantages that the grinding wheel manufacturing spreading device is simple in structure and convenient to operate and is automated, and accordingly manual intervention and preliminary weighing can be omitted; sand can be rotationally spread, accordingly, the grinding wheel spreading uniformity can be effectively improved, the density of sand of various portions of grinding wheels can be kept, and the yield can be increased; the grinding wheel manufacturing spreading device has the excess material sucking function, accordingly, wastage of the sand can be prevented in production procedures, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the field of grinding wheel manufacturing devices, in particular to a device for distributing materials when manufacturing grinding wheels, absorbing excess sand materials and recycling them. Background technique [0002] Grinding wheel, also known as bonded abrasive, is a bonded abrasive with a certain strength that consolidates ordinary abrasives into a certain shape (mostly circular, with a through hole in the center) by a binder. Generally speaking, it consists of abrasives, binders and pores. According to different classifications of bonds, the common ones are ceramic (bond) grinding wheels, resin (bond) grinding wheels, and rubber (bond) grinding wheels. Grinding wheel is the most widely used type of grinding tool. It rotates at high speed when used, and can be used for rough grinding, semi-finishing and Fine grinding as well as grooving and parting off etc. [0003] Grinding wheel is the most important type of abrasiv...

AI Technical Summary

Problems solved by technology

In actual production, unbalanced grinding wheels appear from time to time, the main reason is that the geometric dimensions of the grinding wheel are asymmetrical, and the density of each part of the grinding wheel is not uniform

This unbalanced grinding wheel will vibrate when running at high speed, which will affect the grinding quality

[0004] At present, most of the methods of making grinding wheels are to weigh the sand material in advance, then pour the sand material into the cavity of the grinding wheel mold through the feed port, and then spread the sand material, and whether the sand material paving is uniform directly affects the grinding wheel. The finished product is good or bad. Therefore, this method not only requires manual intervention, but also the geometry of the formed grinding wheel is not uniform, which affects normal use and low yield

[0005] In addition, such as the Chinese Patent Flat Scraper Spreader for Grinding Wheel Forming Machine (publication number: 201597094U, publication date: October 06, 2010) discloses a spreader that uses a ball screw to drive a scraper to achieve linear motion. Although the device realizes the automatic material spreading process and avoids manual intervention in material spreading, but due to the linear suction method used in spreading material, there will be uneven material spreading in practice, especially at the periphery or center of the grinding wheel mold. Inhomogeneity often occurs; in addition, the patent also proposes that there is no need to weigh the sand during production, but it does not take any treatment for the excess sand after spreading. According to its content, it should be absorbed manually Excess abrasive material, therefore, the unit is not fully automated
