Launching mechanism capable of achieving automatic sequence arrangement

The invention discloses a launching mechanism capable of achieving automatic sequence arrangement. The mechanism comprises a ball cabin and a movable ball falling opening. The ball cabinet comprises a hopper type frame and a plurality of ball storage grooves formed inside the frame in parallel in an inclined mode. The higher end of each ball storage groove is provided with an infrared emission head. The movable ball falling opening is formed in the frame and located at the lowest end of the ball storage grooves and comprises a linear motion mechanism and a sliding door assembly moving along the linear motion mechanism in a reciprocating mode. The sliding door assembly is further provided with an infrared receiving head matched with the infrared emission head. Tennis balls on the ball storage grooves can be automatically conveyed out according to a preset sequence, and the mechanism is economical, practical, low in ball blocking rate, easy and reliable to control, low in weight, small in size and low in manufa
