Abstract

A shift lever positioning apparatus for an automatic tin feeding machine comprises a tin feeding mechanism (20). The tin feeding mechanism (20) comprises a shift lever (21), and a reset spring (22) capable of resetting the tin feeding mechanism (20). A rotatable positioning baffle plate (10) is disposed above the tin feeding mechanism (20). A position after the positioning baffle plate (10) downwards rotates is corresponding to a position of the shift lever (21) after the tin feeding machine is opened. During an actual working process, when a worker needs to feed and mount a welding wire, the shift lever is pushed aside, and the resetting of the shift lever is blocked by the positioning baffle plate. Because the positioning baffle plate is fixed above the tin feeding mechanism, the phenomenon that a fixing pin is lost is avoided, and two hands of the worker are free to feed and mount the welding wire, thereby improving the work efficiency; after the welding wire is fed and mounted, an operator uses one hand to push the shift lever aside and uses the other hand to pull up the positioning baffle plate; with the effect of the reset spring, the shift lever and the tin feeding mechanism are shut together and a tin feeding operation is started.
