The feeding device comprises a feeding support 160, a material rack 162, a transverse driving element 164 and a lifting driving element 166. The feeding support 160 is disposed on the bed 110 along the X-axis direction, and mainly plays a role of bearing, and is used for disposing the rack 162, the transverse driving member 164, and the lifting driving member 166.

The lift drive 166 includes a fifth drive source, a linkage, a first set of swing arms 1665, and a second set of swing arms. The fifth driving source may be a motor, which is disposed on the frame 11, i.e., on the feeding support 160, for providing power. The first and second sets of swing arms 1665 and 1665 are respectively located on both sides of the material rest 162, the first set of swing arms 1665 includes a plurality of first swing arms 1665, the second set of swing arms includes a plurality of second swing arms, and the first swing arms 1665 and the second swing arms correspond to each other in the Y-axis direction.

The rack 162 is movably disposed on the frame 11, that is, the rack 162 is spaced apart from a plurality of rollers. The work or material rest 162 extends along the X direction, is provided with a plurality of trays that are used for bearing work piece 7 on it, and a plurality of trays are along the equidistant distribution of X axle direction, and the tray can rotate on work or material rest 162 to drive work piece 7 and rotate, the specific structure of tray is the same with the structure among the prior art, and no longer repeated here.
A first end of the first link 1661 is connected to an output end of the fifth driving source, a second end of the first link 1661 is rotatably connected to a first end of the second link 1663, a second end of the second link 1663 is rotatably connected to a second end of the first swing arm 1665 or a second end of the second swing arm, and a second end of the second link 1663 and the third link 1664 are rotatable linkages.

The rack 162 can thus be moved in the X-axis direction by the fourth driving source 1641.
A limiting hole is formed in a nut of the fourth screw rod pair 1643, a limiting column is arranged on the material rack 162, and the limiting column penetrates through the limiting hole. The lift drive 166 is thus able to drive the spacing post between the first and second positions relative to the spacing aperture. When the limiting column is located at the first position, the distance between the rack 162 and the rack 11 in the third preset direction is smaller than the distance between the rack 162 and the rack 11 in the third preset direction when the limiting column is located at the second position. That is, the lift drive 166 is capable of moving the stack 162 in the Z direction, thereby raising or lowering. When the limiting column is located at the first position, the rack 162 is raised to the high position, and when the limiting column is located at the second position, the limiting column is lowered to the low position. In addition, the cooperation of the limiting column and the limiting hole can prevent the material rest 162 from generating axial movement relative to the fourth lead screw pair 1643, so as to ensure that the material rest 162 can be driven by the fourth driving source 1641 and move along the X-axis direction.
