[0011] The utility model provides a tapered roller through-type centerless grinding feeding mechanism. Compared with the prior art, it has the following beneficial effects:
[0012] 1. The feeding mechanism of the tapered roller through-type centerless grinding mill is provided with a cam and a push rod mechanism. When the cam rotates with the guide wheel, the cam pushes against the roller. When the cam rotates counterclockwise, when the roller passes through the AD section, the baffle blocks the feeding port, so that the roller cannot enter the guide wheel and contact it for processing. When the roller passes through the AB section, the feeding port in the valve slowly opens, and the roller in the roller conveying groove enters the guide wheel from the feeding port to be processed. When the roller passes through the CD section, the valve gradually closes, and the roller is blocked outside the valve, thereby realizing the automatic separation of the roller.
[0013] 2. The feeding mechanism of the tapered roller through-type centerless grinding mill is equipped with a sensing instrument, which is fixedly installed on the column. When the big end of the roller enters the equipment, the sensing instrument senses it and transmits the signal to the control module, thereby stopping the equipment operation to prevent the roller material from being damaged by processing.
