[0002] Powder material plays a very important role in industrial production, and is an indispensable raw material in many industries. During transportation, to ensure the safety of powder material, ton bags are generally used for packaging and transportation. Ton bags are flexible transportation packaging containers, usually made of polyester fibers such as polypropylene and polyethylene, with the advantages of moisture-proof, dust-proof, radiation-resistant, and firm and safe, and can be widely used for packaging various powder, granular and block-shaped materials in chemical industry, building materials, plastics and mineral products. In actual production, ton bags filled with powder raw materials need to be unpacked and poured into a storage bin for production needs. Traditional production plants use manual handling to move ton bags to the storage bin and then manually unpack and pour the powder raw materials.

[0025] like Figure 1 , Figure 2 As shown, a fully automatic unpacking machine includes a roller conveyor 1.

The lower end of the cover 2 is provided with a hopper 6. The orthographic projections of the cutting mechanism 4 and the shaking mechanism 5 are located in the orthographic projection of the hopper 6.

[0026] Among them, such as Figure 2As shown, the cover body 1 is arranged in a "T" shape with the roller conveyor 1, the orthographic projection of the starting end of the cover body 1 overlaps the orthographic projection of the roller conveyor 1, so that the initial position of the sliding bag grabbing mechanism 3 is opposite to the roller conveyor 1, the forklift 8 places the ton bag stacked on the pallet 9 on the roller conveyor 1, the roller conveyor 1 drives the pallet 9 to move forward, when moving to the position directly below the cover body 2, the sliding bag grabbing mechanism 3 can grab the ton bag, at the same time, the lower end of the cover body 2 is opened and the upper end is closed, which can prevent the powder from escaping when falling under gravity, thereby avoiding waste of powder and protecting the working area environment.

[0027] In this embodiment, as shown in the figure, Figure 3 The sliding bag grabbing mechanism 3 includes a walking mechanism 301 which moves along the length direction of the cover body 2, the lower end of the walking mechanism 301 is provided with a telescopic mechanism 302, the lower end of the telescopic mechanism 302 is provided with a bag grabbing mechanism 303, the walking mechanism 301 includes a first motor 304 and a walking wheel 305, the first motor 304 drives the walking wheel 305 to roll on the cover body 2, the bag grabbing mechanism 303 includes a cylinder 306 and a rake body 307 connected with the cylinder 306, a plurality of cylinders 306 drive the rake body 307 to close or open to grab or release the ton bag, the telescopic mechanism 302 is a scissor type lifting mechanism, which is driven to lift by a lifting cylinder, so as to drive the bag grabbing mechanism to move up and down, realize grabbing bags of different layers, the walking wheel 305 is driven by the first motor 304 to roll on the cover body 2, so as to drive the bag grabbing mechanism 303 to move to the position directly above the roller conveyor 1, the lifting cylinder in the telescopic mechanism 302 drives the scissor type lifting mechanism to move downward by a set distance, the cylinder 306 drives the rake body 307 to close and insert into the ton bag to grab the ton bag, then the telescopic mechanism 302 resets, and the walking mechanism 302 works to drive the ton bag to pass through the cutter mechanism 4 and the material shaking mechanism 5 in turn to release the powder raw material into the stock bin 6.

[0028] It is worth noting that in other embodiments, the telescopic mechanism 302 can be a cylinder or a hydraulic cylinder, of course, in order to realize high-precision lifting, the telescopic mechanism can also be a linear module.

[0029] In this embodiment, as shown in the figure, Figure 4 The cutter mechanism 4 includes a second motor 401, the second motor 401 is arranged outside the cover body 2, the output end of the second motor 401 is connected with a rotating shaft 402, a plurality of cutters 403 are uniformly arranged on the rotating shaft 402, the ton bag passing through is cut by a plurality of cutters 403, and the powder raw material falls into the stock bin 6 under gravity.

[0030] In this embodiment, as shown in the figure, Figure 5 , Figure 6As shown, in order to release the powder raw materials remaining in the ton bag into the hopper, a shaking structure 5 with a reciprocating extrusion function is designed. The shaking mechanism 5 includes a reciprocating rod 501, which penetrates the cover 2. The reciprocating rod 501 is provided with multiple extrusion strips 502. Guides 503 are provided on the left and right sides of the reciprocating rod 501. A reciprocating drive device 504 is provided at one end of the reciprocating rod 501. The reciprocating drive device 504 includes a third motor 505, which is located on the outside of the cover 2. The output end of the third motor 505 is connected to a cam disk 506. A pusher is provided inside the cam disk 506. The pusher 507 is rotatably connected to the reciprocating rod 501. The third motor 505 drives the cam disk 506 to rotate, thereby driving the pusher 507 to move along the cam trajectory within the cam disk 506. Since the reciprocating rod 501 can only move linearly under the limiting action of the guide 503, the rotation of the cam disk 506 can drive the reciprocating rod 501, which is rotatably connected to the pusher 507, to move back and forth in a linear motion. Since most of the raw material in the ton bag falls into the hopper, the ton bag is in a suspended state. When the reciprocating rod 501 moves back and forth, the extrusion bar squeezes the suspended ton bag back and forth, thereby releasing the remaining powder raw material into the hopper 6.

[0031] Among them, such as Figure 7 As shown, in order to improve the smoothness of the movement of the reciprocating rod 501, the guide 503 includes a fixed plate 508 and guide wheels 509 arranged symmetrically up and down along the fixed plate 508. The guide wheels 509 contact the reciprocating rod 501. Through the rolling friction of the guide wheels 509, the third motor 505 with a smaller power can drive the reciprocating rod 501 to move, while reducing friction and improving working stability and service life.

[0032] In this embodiment, as Figure 2 As shown, in order to collect waste bags, a collection box 7 is provided at the end of the cover 2. The driving walking mechanism 301 moves to the end of the cover 2, and the cylinder 306 drives the rake body 307 to open. The ton bag falls into the collection box 7 for temporary storage under the action of gravity. The collection box 7 is detachably connected to the cover 2. The waste bag can be removed for subsequent processing by opening the collection box 7 periodically.
