They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0027] The following is combined with Figure 1-6 The utility model is further described.

[0028] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: it includes a base 1, a frame 2 is fixedly installed on the base 1, the frame 2 provides support and fixation, a feed conveying track 10 is fixedly installed on the frame 2, a waste bag conveying track 11 is provided on one side of the feed conveying track 10, a first slide rail 4 and a second slide rail 5 are fixedly installed on the frame 2, a slide seat 9 is slidably installed between the first slide rail 4 and the second slide rail 5, a hopper 12 is fixedly installed on the base 1, an unpacking table 13 is fixedly connected to the hopper 12, a cutting disc 14 is provided on the unpacking table 13, a driving mechanism is provided in the frame 2, and a clamping mechanism is provided under the slide seat 9.

[0029] The material bag is placed on the feed conveyor track 10, and the feed conveyor track 10 conveys the material bag. After the material bag is conveyed to the taking position, the clamping mechanism clamps and takes the material bag, and the driving mechanism drives the material bag to rotate and rotates the material bag to the position of the hopper 12. The lower end of the material bag contacts the cutting disc 14, and the rotating cutting disc 14 cuts the lower end of the material bag, and the raw materials in the material bag fall into the hopper 12, realizing automatic unpacking of the material bag. After the raw materials completely fall into the hopper 12, the driving mechanism continues to drive the material bag to rotate above the waste bag conveying track 11, and the clamping mechanism releases the waste bag, and the waste bag falls on the waste bag conveying track 11, and the waste bag conveying track 11 moves the waste bag out of the frame 2. The clamping mechanism is driven by the driving mechanism to rotate cyclically, so as to realize automatic cyclic unpacking of the material bag, effectively reducing the labor intensity of the workers and greatly improving the work efficiency of unpacking.

[0030] It is further explained that the driving mechanism includes a mounting platform 3 fixedly connected to the frame 2 and a rotating motor 6 fixedly mounted on the mounting platform 3, a turntable 7 is fixedly connected to the driving shaft of the rotating motor 6, five groups of connecting rods 8 are fixedly connected to the circumferential surface of the turntable 7, and the end of the connecting rod 8 away from the turntable 7 is fixedly connected to the slide 9.

[0031] The mounting platform 3 provides installation conditions for the rotating motor 6. The rotating motor 6 drives the turntable 7 to rotate. The turntable 7 drives the slide 9 to rotate through the connecting rod 8. The slide 9 drives the clamping mechanism to rotate, thereby moving the material bag and rotating the material bag to the designated area.

[0032] It is further explained that the clamping mechanism is arranged on the mounting plate 17 below the slide 9, the bag grabbing seat 20 is fixedly installed below the mounting plate 17, and two groups of sliders 23 are slidably installed in the bag grabbing seat 20. The lower ends of the two groups of sliders 23 are rotatably installed with clamping rods 27, and the two groups of clamping rods 27 are rotatably connected.

[0033] When the two groups of sliders 23 move relatively close to each other, the upper ends of the two groups of clamping rods 27 move relatively close to each other, and the lower ends of the two groups of clamping rods 27 move relatively close to each other to clamp the material bags on the feed conveying track 10, and the driving mechanism rotates the clamped material bags to the hopper 12 for unpacking; when the two groups of sliders 23 move relatively far away from each other, the upper ends of the two groups of clamping rods 27 move relatively far away from each other, and the lower ends of the two groups of clamping rods 27 move relatively far away to release the clamping of the material bags, and the unpacked waste bags are discarded on the waste bag conveying track 11.

[0034] It is further explained that a mounting groove 21 is opened in the bag grabbing seat 20, and two sets of sliders 23 are slidably installed in the mounting groove 21. A second motor 26 is fixedly installed at one end of the bag grabbing seat 20, and the driving shaft of the second motor 26 is fixedly connected to a bidirectional screw rod 22. The bidirectional screw rod 22 is rotatably installed in the mounting groove 21, and the bidirectional screw rod 22 is threadedly connected to the two sets of sliders 23.

[0035] The second motor 26 drives the bidirectional screw rod 22 to rotate, and the bidirectional screw rod 22 pushes the two groups of sliders 23 to move relative to each other. The forward and reverse rotation of the second motor 26 realizes the relative movement of the two groups of sliders 23 towards and away from each other, thereby clamping the material bag and discarding the waste bag, and improving the convenience of using the clamping mechanism.

[0036] It is further explained that limiting grooves 24 are provided on both side walls of the installation groove 21 , and limiting blocks 25 are slidably installed in the limiting grooves 24 . The limiting blocks 25 are fixedly installed on the side surfaces of the slider 23 .

[0037] The limiting groove 24 cooperates with the limiting block 25 to guide and limit the movement of the slider 23, preventing the slider 23 from flipping when the bidirectional screw rod 22 rotates, and improving the stability of the two groups of sliders 23 when moving in the installation groove 21.

[0038] It is further explained that a telescopic damping rod 15 is fixedly installed below the slide 9, the lower end of the telescopic damping rod 15 is fixedly connected to the mounting plate 17, the outer sleeve of the telescopic damping rod 15 is provided with a spring 16, a first motor 18 is fixedly installed on the mounting plate 17, and a cam 19 is fixedly installed on the drive shaft of the first motor 18.

[0039] After the material bag is rotated onto the hopper 12 and the rotating cutting disc 14 cuts open the lower end of the material bag, the first motor 18 drives the cam 19 to rotate, and the cam 19 contacts the bottom of the slide 9. As the cam 19 rotates, the distance between the slide 9 and the mounting plate 17 changes. Since the slide 9 is slidably installed between the first slide rail 4 and the second slide rail 5, the mounting plate 17 moves up and down, and the mounting plate 17 drives the clamping mechanism and the material bag clamped therein to shake up and down, and the raw materials in the unpacked material bag are thoroughly cleaned out to avoid waste of raw materials. The telescopic damping rod 15 cooperates with the spring 16 to improve the stability during the shaking process.

[0040] Specific reference is made to the following operations: workers place the material bag on the feed conveyor track 10 through the external conveyor line, and then the feed conveyor track 10 conveys the material bag to the designated area, the second motor 26 drives the bidirectional screw 22 to rotate, and the bidirectional screw 22 pushes the two sets of sliders 23 to move relatively close, and the lower ends of the two sets of clamping rods 27 clamp the material bag on the feed conveyor track 10, and the rotating motor 6 drives the turntable 7 to rotate, and the turntable 7 drives the slide 9 to rotate through the connecting rod 8, and the clamped material bag is rotated to the position of the hopper 12, and the lower end of the material bag contacts the cutting disc 14, and the rotating cutting disc 14 cuts the lower end of the material bag. After the bag is cut open, the raw materials in the bag fall into the hopper 12. At this time, the first motor 18 drives the cam 19 to rotate, and the cam 19 mounting plate 17 moves up and down. The mounting plate 17 makes the bag shake up and down, and the raw materials in the bag are thoroughly cleaned into the hopper 12. The bag is then rotated to the top of the waste bag conveying track 11, and the second motor 26 is reversed. The lower ends of the two sets of clamping rods 27 are relatively far apart, and the waste bag falls on the waste bag conveying track 11. The waste bag conveying track 11 moves the waste bag to the outside. When performing all the actions, the rotating motor 6 is constantly rotating, which effectively saves the problem of time waste caused by reciprocating motion.
