[0019] The bagged materials are carried by the loading rack 8, and then the loading rack 8 is moved forward and backward, up and down, and flipped by the provided translation mechanism 4, gantry 5, lifting mechanism 6, and rotating mechanism 7, so that the bagged materials on the loading rack 8 are tilted or flipped, and the bagged materials are allowed to fall freely into the feed box 2, and the bags on the loading rack 8 are punctured and fixed by the fixing device 9 to prevent the material bags from falling into the feed box 2.

[0020] As one of the embodiments, the translation mechanism 4 includes a guide rail 41, a screw rod 42, a slider 43 and a servo motor 44. The guide rail 41 has a screw rod 42 rotatably installed inside it, the guide rail 41 has a slider 43 slidably installed inside it, and the slider 43 is in a threaded sleeve relationship with the screw rod 42. The front end of the guide rail 41 is fixedly connected to the servo motor 44, and the output shaft of the servo motor 44 passes through the guide rail 41 and is fixedly connected to the screw rod 42.
[0021] When translating forward and backward, the servo motor 44 is turned on, and the servo motor 44 drives the screw rod 42 to rotate inside the guide rail 41. Since the slider 43 is threadedly connected with the screw rod 42 and under the sliding limit of the guide rail 41, the slider 43 can slide freely forward and backward inside the guide rail 41, thereby realizing the forward and backward translation movement of the gantry 5.
[0022] As one of the embodiments, the lifting mechanism 6 includes a double-headed motor 61, a transmission shaft 62, a winding drum 63, and a wire rope 64.

A wire rope 64 is wound around the surface of each winding drum 63, and the end of the wire rope 64 passes through the gantry 5 and is fixedly connected to the movable block 52.
[0023] During lifting, the double-headed motor 61 is turned on, and the double-headed motor 61 drives the two transmission shafts 62 to operate synchronously, so that the winding drum 63 rotates, and the winding drum 63 unwinds the wire rope 64, so that the movable block 52 can slide freely up and down inside the slide groove 51, thereby driving the loading frame 8 to lift and lower on the gantry 5.
[0024] As one of the embodiments, the rotating mechanism 7 includes a rotating cylinder 71 and a connecting rod 72. A connecting rod 72 is rotatably installed in the middle of each movable block 52. A rotating cylinder 71 is fixedly connected to the side of one of the movable blocks 52, and the free end of the rotating cylinder 71 is fixedly connected to the connecting rod 72.
[0025] When flipping, the rotating cylinder 71 is turned on, and the rotating cylinder 71 drives the connecting rod 72 to rotate, so that the connecting rod 72 drives the loading rack 8 to tilt or rotate 90°-180°, thereby realizing the unloading processing of the material bags on the loading rack 8.
[0026] As one of the embodiments, the material carrier 8 includes a U-shaped load-bearing plate 81 and a baffle 82 . The middle parts of both ends of the U-shaped load-bearing plate 81 are fixedly connected to the two connecting rods 72 , respectively. The baffle 82 is fixedly connected to the top of the front end of the U-shaped load-bearing plate 81 .
[0027] When unloading the bagged materials, the loading rack 8 is placed on the top surface of the base 1 by using the translation mechanism 4 , the gantry 5 , and the lifting mechanism 6 , and then the material bag is placed on the top surface of the U-shaped loading plate 81 and close to the baffle plate 82 .
[0028] As one of the embodiments, the fixing device 9 includes a telescopic cylinder 91 and a cone thorn 92. The two telescopic cylinders 91 are fixedly installed on the bottom of both sides of the U-shaped supporting plate 81. The piston end of each telescopic cylinder 91 is fixedly connected to a cone thorn 92, and the cone thorn 92 penetrates the U-shaped supporting plate 81.
[0029] After loading the material bag, the telescopic cylinder 91 is turned on, and the telescopic cylinder 91 drives the cone 92 to extend and retract to puncture the material bag, thereby hanging the material on the U-shaped supporting plate 81, thereby effectively preventing the material bag from detaching from the U-shaped supporting plate 81 and falling into the feed box 2 when tilting and unloading.
[0030] The working principle of the utility model is as follows: when unloading bagged materials, the loading rack 8 is placed on the top surface of the base 1 by means of the translation mechanism 4, the gantry 5, and the lifting mechanism 6, and then the material bag is placed on the top surface of the U-shaped load-bearing plate 81 and close to the baffle plate 82, and then the telescopic cylinder 91 is turned on, and the telescopic cylinder 91 drives the cone thorn 92 to extend and retract to puncture the material bag, so that the material is suspended on the U-shaped load-bearing plate 81, and then the double-headed motor 61 is started, and the double-headed motor 61 drives the two transmission shafts 62 to operate synchronously, so that the winding drum 63 rotates, so that the winding drum 63 reels the wire rope 64, and the loading rack 8 is lifted to a height higher than the feed box 2. Then, the servo motor 44 is turned on, and the servo motor 44 drives the screw rod 42 to rotate inside the guide rail 41. Since the slider 43 is threadedly connected with the screw rod 42, and under the sliding limit of the guide rail 41, the slider 43 slides freely inside the guide rail 41 until the gantry 5 and the loading rack 8 are moved to just above the feed box 2. Finally, the rotating cylinder 71 is turned on, and the rotating cylinder 71 drives the connecting rod 72 to rotate, so that the connecting rod 72 drives the loading rack 8 to tilt or rotate 90°-180°, thereby realizing the unloading processing of the material bags on the loading rack 8, which greatly reduces the labor intensity of the staff and reduces the risk of the material bags falling.
