Description

Technical Field

[0001] The utility model relates to the technical field of resin grinding wheel production, and more specifically, to a feeding device for making resin grinding wheel pieces. Background Art

[0002] Resin grinding wheel is a grinding wheel made of resin with high strength, used in cutting discs, double-end faces, heavy-duty grinding wheels, polishing wheels, etc. It has certain elasticity, low heat resistance, good self-sharpening, simple production, and short process cycle. It is widely used in rough grinding, rough grinding, cutting and free grinding, such as grinding steel ingots and deburring castings. In the process of making resin grinding wheels, feeding is an indispensable process.

[0003] At present, most of the feeding process in the production of resin grinding wheels is done manually, which is very inconvenient and greatly reduces work efficiency, so that the output cannot be effectively improved. At the same time, it may cause the amount of feeding each time to deviate, so the products produced are not uniform and the quality cannot be effectively guaranteed.

[0004] After searching, a Chinese patent with announcement number CN213592668U discloses a material feeding device for resin grinding wheel production, in which a first gear is fixedly connected to the surface of a rotating sleeve, a rotating disk is placed inside a feeding frame, and the outer ring of the rotating disk is fitted with the inner cavity of the feeding frame, an opening is provided on the surface of the rotating disk, and a second gear meshing with the first gear is fixedly connected to the inner wall of the opening, a storage trough is provided on the surface of the rotating disk that is fitted with the inner cavity of the feeding frame, and a plurality of storage troughs are provided, a feeding funnel used in conjunction with the storage trough is connected to the top of the feeding frame, and a discharging funnel used in conjunction with the storage trough is connected to the bottom of the feeding frame. By providing a feeding device, manual feeding can be replaced, reducing manual work intensity, effectively improving work efficiency, and reducing errors in the manual feeding process.

[0005] When the material feeding device for the production of the resin grinding wheel is actually used, some heavier materials may settle at the bottom of the device during the feeding process, while lighter materials may float on the surface, which may cause the raw materials to have a local concentration that is too high or too low, resulting in unstable performance of the grinding wheel and affecting product quality.
