The invention relates to the technical field of
glass engraving and milling machines, in particular to an automatic material taking and placing mechanism of an
engraving and milling
machine. According to the technical scheme, a box body is arranged, an inner cavity is formed in the box body, conveying mechanisms used for conveying workpieces are arranged on the left portion and the right portion of the inner cavity correspondingly, auxiliary feeding mechanisms are arranged on the cavity walls of the left end and the right end of the inner cavity correspondingly, a rotating column is arranged on the lower portion of the inner cavity, and a
machining rotating disc is rotationally arranged on the top of the rotating column; a hollow sleeve is arranged on the bottom wall of the
machining rotary disc, a
bevel gear ring is arranged at the outer end of the hollow sleeve, and limiting mechanisms used for positioning workpieces are evenly arranged on the
machining rotary disc. Through cooperation of the machining
rotating disc, the conveying mechanism, the bidirectional lead screw, the suction cup mechanism, the connecting rod, the
bevel gear, the
bevel gear ring, the positioning plate, the
cam and the abutting rod, the
engraving and milling
machine can conduct feeding and discharging at the same time through the simple structure, shutdown for material replacement is not needed, material taking or discharging is conducted through the conveying mechanism, and the production efficiency is improved. And the working efficiency of the
engraving and milling
machine is effectively improved.
