[0019] The embodiment of the present invention provides an automatic flipping and unpacking machine, such as Figure 1-2As shown, it includes a silo 1, a machine cover 2, a material discharging bottom section 3, a material bracket 4, a rotating cylinder 5, a connecting rod 6, a main shaft 7, a main bracket 8, a flip cylinder 9, a material carrier 10, a cutting knife 11, a cutting cylinder 12, a hook 13, a hook cylinder 14, a guide column 15, a guide frame 16, and a buffer 17. The material bracket 4 is fixed in the silo 1. The silo 1 is provided with a machine cover 2, and the machine cover 2 is located above the material bracket 4. The silo 1 is provided with a material discharging bottom section 3, and the material discharging bottom section 3 is located below the material bracket 4. A cutting assembly is provided between the material bracket 4 and the material discharging bottom section 3, and the cutting assembly includes a cutting knife 11 and two cutting cylinders 12, and the two ends of the cutting knife 11 are respectively connected to the cutting cylinder 12, and the cutting cylinder 12 is fixedly connected to the silo 1. The cutting cylinder 12 adopts a linear cylinder. Rotating cylinders 5 are symmetrically arranged on both sides of the outside of the silo 1. The piston rods of the two rotating cylinders 5 are connected to the two ends of the main shaft 7 through the connecting rod 6 respectively, and the main shaft 7 passes through the silo 1. The rotating cylinder 5 is rotatably connected to the silo 1, and the piston rod of the rotating cylinder 5 is rotatably connected to the connecting rod 6, and the connecting rod 6 is fixedly connected to the main shaft 7. The rotating cylinder 5 drives the main shaft 7 to rotate. The lower end of the main bracket 8 is fixedly connected to the main shaft 7, and the upper end of the main bracket 8 is connected to the material carrier 10 through the flip cylinder 9. The flip cylinder 9 drives the material carrier 10 to flip. A hook assembly is arranged on the back of the material carrier 10. The hook assembly includes a hook cylinder 14 and three hooks 13, and the hooks 13 are arranged vertically at equal intervals, and the hooks 13 are all connected to the hook cylinder 14. The hook cylinder 14 is fixed on the material carrier 10, and a through hole for the hook 13 to pass through is opened on the material carrier 10. The hook cylinder 14 drives the hook 13 to rotate, so that the front part of the hook 13 passes through the through hole and extends to the front of the material carrier 10. A guide column 15 is fixed on the inner wall of the silo 1, and the material carrier 10 is connected to the guide column 15 through a guide frame 16. The material carrier 10 is fixedly connected to the guide frame 16. The guide frame 16 adopts a U-shaped frame, and the guide column 15 is inserted in the U-shaped frame. Buffers 17 used in conjunction with the material carrier 10 are symmetrically fixed on the inner walls on both sides of the silo 1. The material carrier 10 is located between the material bracket 4 and the buffer 17. The design of the guide frame 16, the guide column 15 and the buffer 17 reduces the possibility of failure during the movement of the material carrier 10. A control box (not shown in the figure) is fixed on the outside of the silo 1, and the control box is connected to the cutting cylinder 12, the rotating cylinder 5 and the flipping cylinder 9. The operator can pre-set the control box to control the number of actions, time intervals, etc. of the cutting cylinder 12, the rotating cylinder 5 and the flipping cylinder 9 to achieve continuous automatic operation, such as the stabilization time after the hook 13 hooks the material bag 18, the cutting speed of the cutting knife 11, the number of times the material bag 18 shakes back and forth, etc.

[0020] When in use, the worker places the material packaging bag 18 on the material bracket 4, and then operates on the touch screen of the control box to control the rotation cylinder 5, the flip cylinder 9, etc. to work. Specifically, the piston rod of the rotation cylinder 5 extends, driving the main shaft 7 to rotate, so that the upper end of the main bracket 8 moves toward the material bracket 4; at the same time, the flip cylinder 9 works to make the front of the material carrier 10 face the material bracket 4; finally, the front of the material carrier 10 is pressed on the material packaging bag 18. The hook cylinder 14 works to drive the hook 13 to rotate, and the front end of the hook 13 passes through the through hole and is inserted into the material packaging bag 18. The cutting cylinder 12 works to drive the cutting knife 11 to move and cut the lower part of the material packaging bag 18. The piston rod of the rotation cylinder 5 is extended and retracted in a small range many times, and the material packaging bag 18 is driven to shake back and forth many times through the connecting rod 6, the main shaft 7, the main bracket 8, and the material carrier 10, so that the material in the material packaging bag 18 falls into the discharge bottom section 3. Shaking the material packaging bag 18 can ensure that all the materials in the material packaging bag 18 can fall into the discharge bottom section 3, and no materials remain in the material packaging bag 18. The piston rod of the rotating cylinder 5 contracts, driving the main shaft 7 to rotate, so that the upper end of the main bracket 8 moves toward the buffer 17; at the same time, the flip cylinder 9 works to make the front of the material carrier 10 face the buffer 17; finally, the front of the material carrier 10 is attached to the buffer 17. The hook cylinder 14 drives the hook 13 to rotate, and the hook 13 is retracted on the back of the material carrier 10. The material packaging bag 18 slides off the material carrier 10 and falls outside the silo 1.
