[0023] The upper hinged seat 21 on the material feeding turning table 2 is located above the hopper 11 on the elevator 1, and when the material basket 5 is turned over with the material basket supporting plate 22, the workpiece can be output from the discharge port of the material basket 5 into the hopper 11; the material baffle plate 51 is provided with a bolt assembly, and when the material basket 5 is feeding, the lower end of the material baffle plate 51 is fixed to the material basket 5 through the bolt assembly, and then when the material basket 5 rotates and moves, the workpiece in the basket cannot fall out of the discharge port; and when feeding into the hopper 11, the bolt assembly needs to be opened, and then the discharge port of the material basket 5 will be opened.

[0024] See Figure 2 As shown, the support leg 52 on the basket 5 includes a vertical square tube 521, a tapered transition tube 522 is formed at the lower end of the square tube 521, and a rectangular tubular base 523 is formed at the lower end of the transition tube 522; the area of the lower end of the base 523 is larger than the area of the lower end of the square tube 521, thereby effectively supporting the basket 5;

The flip-type loading device mainly transports the material basket 5 to the material basket supporting plate 22 by hoisting. The material basket 5 is connected to the material basket supporting plate 22 by the support legs 52. Then, when the material basket 5 is tilted to feed, the material basket 5 and the material basket supporting plate 22 will not move relative to each other.

[0030] When feeding is needed, start the oil pressure controller 3, which can drive the piston rod of the flip cylinder 4 to extend, so that the basket supporting plate 22 can rotate upward around the upper hinge seat 21. The baffle plate 51 in the basket 5 is vertical due to gravity, and then its discharge port is opened. Part of the workpiece in the basket 5 slides into the hopper 11, and part remains in the basket 5. When the workpiece in the hopper 11 is lifted, the piston rod of the flip cylinder 4 is driven to extend, and then the flipping angle of the basket 5 is increased. The workpiece can be output from the basket 5 into the hopper 11, thereby realizing the successive feeding of the workpiece.
