Patent ID: 8794958

Claim:
An ejection mechanism comprising: a base; a rotation disk; and a feeding station; wherein the base is configured for mounting of the rotation disk and the feeding station, the base capable of being disposed adjacent to an elbow pipe forming device and corresponding to a lifting shaft of the elbow pipe forming device; the base has a driving motor, and the driving motor is rotatably connected to a rotating gear such that the rotating gear is able to be driven by the driving motor to rotate on the base; the base further includes an arched guiding track, and the arched guiding track is disposed around the rotating gear; the base further includes a supporting element respectively on two sides of the base, and each supporting element is provided with a rolling wheel at an end of the supporting element; the rotation disk is fan-shaped and is rotatably coupled to the base by a rotating shaft such that the rotation disk is aligned above the arched guiding track; and the rotation disk is further provided with an arched row of teeth on a bottom of the rotation disk corresponding to the rotating gear of the base, and the arched row of teeth are adjacent to an inner edge of the arched guiding track of the base; the rotation disk driven by the rotating gear causes the arched row of teeth to rotate and also to simultaneously cause the rotation disk to rotate around the rotating shaft on the arched guiding track; the rotation disk further includes a guiding slot and a plurality of securing holes; the feeding station is coupled to the guiding slot and locked with the screw holes of the rotation disk with a plurality of securing members, the feeding station further including a limiting slot with a feeding member, an end of the feeding member pivoted with a limiting rod, another end of the limiting rod protruding through the limiting slot and connected to a stopping block; the limiting rod is jacketed with a spring and two ends of the spring respectively push against the limiting slot and the feeding member such that the feeding member is pushed out by the spring and stopped by the stopping block; and the limiting slot is covered by a cover configured to secure the feeding member.
