Automatic material feeding and material scraping device for grinding wheel production

Abstract

The invention discloses an automatic material feeding and material scraping device for grinding wheel production. The device comprises a platform, a material box, a controller, a material conveying pipe, a material conveying machine, a discharging pipe, a first pushing rod motor, a sliding block, a second pushing rod motor and a material scraping plate; the material box, the controller, the material conveying machine and the first pushing rod motor are installed on the platform, the first pushing rod motor is located on the right side of the material box, and the controller is located on the left side of the material conveying machine; the material box is connected to the material conveying machine through the material conveying pipe, the discharging pipe is installed on the material conveying machine, and the tail end of a pushing rod of the first pushing rod motor is fixedly connected to the tail end of the sliding block; and the second pushing rod motor is fixedly installed on the lower surface of the top end of the sliding block, the tail end of a pushing rod of the second pushing rod motor is fixedly connected to the material scraping plate, and the tail end of the dischargingpipe is fixedly installed on the side surface of the material scraping plate. According to the device, the defects in the prior art are overcome, material feeding and material scraping are carried out at the same time, forming material is uniformly distributed in a mold, so that a bridge phenomenon in the material scraping process is eliminated, and manufactured grinding wheels are uniform in hardness and stable in quality.

Description

technical field [0001] The invention relates to the technical field of grinding wheel production, in particular to an automatic feeding and scraping device for grinding wheel production. Background technique [0002] A grinding wheel is a grinding tool that consolidates ordinary abrasives into a certain shape with a bond and has a certain strength. It is generally composed of abrasives, bonds and pores. These three parts are often called the three elements of consolidated abrasives. Grinding wheels can be divided into ceramic, resin and rubber grinding wheels according to different binders. The molding process of resin grinding wheel in the prior art can be divided into cold pressing process, semi-hot pressing process and hot pressing process. Before the grinding wheel is pressed and formed, it is necessary to add the grinding wheel forming material into the mold and carry out the scraping. The current feeding and scraping technology and equipment are generally one-time fee...

Problems solved by technology

Due to the one-time feeding, it is easy to cause the material to be too concentrated and unevenly distributed, and the difference in bulk density between the place where the stirring rod passes and the place where the stirring rod does not pass during stirring is likely to cause a difference in bulk density, and because the particle size of the molding material is relatively fine, it is easy to produce bridge phenomenon, especially when forming The finer the particle size, the more serious the bridging phenomenon, and it is difficult to eliminate

The equipment currently used can only ensure that the surface of the molding material in the grinding wheel mold is scraped flat, while the molding material in the lower layer is still uneven, and the quality of the pressed grinding wheel blank is uneven, resulting in uneven strength and hardness of the final grinding wheel product. unreliable quality
