Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a raw material mixing device for producing resin grinding wheels. Background Art

[0002] Grinding wheels are also called bonded abrasives. Grinding wheels are bonded abrasives that are formed into a certain shape and have a certain strength by bonding ordinary abrasives. When bonding the bond and abrasives, the materials need to be fully mixed to facilitate subsequent processing and manufacturing.

[0003] After searching, it was found that the publication number is CN216358980U, and the name is a raw material mixing device for resin grinding wheel production. The application proposes that in production, the abrasive and the resin binder are mixed together for stirring. The existing method is to put the abrasive and the resin binder into a barrel together for stirring. This method easily causes the resin binder and the abrasive to mix slowly, which is not conducive to sufficient mixing. When the abrasive in the mixing barrel is stirred in the feed pipe, the resin binder is sprayed into the abrasive from the discharge port, so that the resin binder is fully mixed with the abrasive of different depths, and the resin binder is evenly sprayed into the abrasive in the mixing barrel, which fully improves the mixing speed of the resin binder and the abrasive and improves the mixing effect. However, when the application is used, since the discharge port is always in an open state, during the mixing process, the raw material can easily pass through the discharge port into the feed pipe, thereby causing the raw material deposition and blockage inside the feed pipe, which is very troublesome to clean and use later, affecting the stability and reliability of use. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
