Feeding mechanism and tapping machine

The invention discloses a feeding mechanism which comprises a feeding mechanism body, a main machining block and a feeding channel, one end of the feeding channel is connected with the main machining block, the feeding mechanism body comprises a feeding block and a displacement device driving the feeding block to move on the main machining block, and the feeding block is provided with at least two limiting grooves used for containing materials. A transversely-formed groove is formed in the middle of the main machining block, first groove channels and second groove channels are formed in the two sides of the groove respectively, the number of the first groove channels and the number of the second groove channels are the same as the number of the limiting grooves, and a sensor used for detecting whether materials enter the limiting grooves from the feeding channel or not is further arranged on the main machining block. According to the feeding mechanism, multi-station feeding can be completed through one feedin
