Problems solved by technology
The inventor found in practice that although the service life of the grinding roller is extended after adding the wear-resistant layer, compared with the past, a certain amount of use cost is saved, but once there is a wear on the outer surface of the grinding roller, the entire grinding roller needs to be replaced, and the use cost remains the same. It is relatively high, and it is still inconvenient to replace after wear and tear. It takes a long time to replace the grinding roller, which brings inconvenience to the normal operation of the grinding equipment.

The invention discloses a novel grinding roller with a quick-changing shell, comprising a roller spindle, a roller block and the quick-changing shell.One end of the roller block is peripherally provided with a large circular groove, and the other end of the roller block is provided with a small circular groove; one end of each of left and right semicircular conical shells of the quick-changing shell is connected with a large arc plate, the other end being connected with a small arc plate; a butt joint of the large arc plate is provided with a connecting plate, the large arc plate is inserted into the large circular groove, and the small arc plate is inserted into the small circular groove; the large arc plate is distributed a plurality of threaded holes, and the roller block is connected with the large arc late through hex screws; the small arc plate is distributed a plurality of radial positioning light holes, and the roller block is connected with the small arc plate through the hex screws and the light holes in this position.The invention also provides a method of changing the quick-changing shell of the novel grinder with the quick-changing roller.A new shell can be provided after the shell is abraded without changing the whole grinding roller, on one hand, equipment replacement cost is reduced, and on the other hand, work efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of machinery, in particular to a grinding roller used in grinding equipment. Background technique [0002] The grinding rollers in the grinding equipment wear out quickly, and the cost of use remains high. It is inconvenient to replace the grinding roller after it is worn out, it is time-consuming and laborious, the labor intensity of the workers is high, and the work efficiency is low. Faced with the technical problems of fast wear and short service life of the grinding rollers in the grinding equipment, a technical solution for setting a wear-resistant layer on the outer surface of the grinding rollers appeared, that is, using a "wear-resistant layer" to solve the problem of "fast wear". This is also a natural process of technological development. The inventor found in practice that although the service life of the grinding roller is extended after adding the wear-resistant layer, compared with the past,...
