[0026] Please also refer to Figure 1 and Figure 2, Figure 1 1 is a schematic structural diagram of an automatic unpacking device 100 provided in an embodiment of the present application; Figure 2 Figure 1 is a cross-sectional view of an automatic unpacking device 100 provided in an embodiment of the present application. The automatic unpacking device 100 includes a hook assembly (not shown) and a feeding device 6. During unpacking, the hook assembly of the automatic unpacking device 100 moves the ton bag to the feeding device 6, which cuts the ton bag, causing powder to flow out of the cut and into the feeding device 6.

[0027] The unloading device 6 includes a first hopper 61, a second hopper 62 and a cutting structure 5. The first hopper 61 is provided with a accommodating chamber 611. The second hopper 62 includes a first end 621 and a second end 622 opposite to each other. The second end 622 is accommodated in the accommodating chamber 611 and is spaced apart from the side wall of the first hopper 61. The first hopper 61 is connected to the second hopper 62 at a position between the first end 621 and the second end 622. The second end 622 is provided with a feed port 6221 connected to the accommodating chamber 611. The cutting structure 5 is arranged in the first hopper 61 and extends from the feed port 6221 to the second hopper 62. When unpacking the ton bag, the hook assembly moves the ton bag to the second hopper 62, and the cutting structure 5 cuts a notch in the bottom of the ton bag. Under the action of gravity, the powder falls from the feed port 6221 into the accommodating chamber 611. In an embodiment of the present application, the second hopper 62 can reduce the opening size of the first hopper 61 on the side close to the second hopper 62. The second hopper 62 can block the dust stirred up when the powder falls into the accommodating chamber 611, thereby reducing or preventing the dust from floating out of the accommodating chamber 611, thereby reducing the dust problem in the automatic unpacking equipment 100, reducing the failure rate of the automatic unpacking equipment 100, improving the service life, and avoiding the problem of dust explosion.

[0028] The angle between the side wall of the first hopper 61 and the height direction Z of the material discharge device 6 is smaller than the angle between the side wall of the second hopper 62 and the height direction Z of the material discharge device 6, that is, the inclination of the side wall of the first hopper 61 is greater than the inclination of the side wall of the second hopper 62. Figure 2 The middle Z-axis direction is defined as the height direction of the unloading device 6. This, on the one hand, reduces the collision angle when the powder collides with the side wall of the first hopper 61, lessens the intensity of the collision, and thus reduces the dust generated by the collision. On the other hand, a relatively closed accommodating space is formed between the outer wall of the second end 622 of the second hopper 62 and the inner wall of the first hopper 61. As dust rises along the accommodating chamber 611, it floats into this accommodating space, effectively blocking the dust with the second hopper 62 and preventing it from floating out of the feed port 6221.

[0029] The second hopper 62 has a first sidewall 6231 and a second sidewall 6232. The first sidewall 6231 is connected to the side of the second sidewall 6232 away from the first hopper 61. The first hopper 61 is connected to the second sidewall 6232. The angle between the second sidewall 6232 and the height direction Z of the discharge device 6 is less than or equal to the angle between the first sidewall 6231 and the height direction Z of the discharge device 6. This, on the one hand, increases the volume of the second hopper 62 at the location corresponding to the first sidewall 6231, facilitating the entry of large bags into the second hopper 62, helping to avoid positional interference between the large bags and the second hopper 62, and reducing the difficulty of positioning the hook assembly. On the other hand, the inclination of the second sidewall 6232 helps prevent powder from accumulating on the second sidewall 6232 after falling on it, allowing the powder to slide off quickly and reducing dust generated when the powder collides with the second sidewall 6232. Along the height direction of the blanking device 6, the specific dimensions and the ratio of the dimensions of the first side wall 6231 and the second side wall 6232 can be specifically set according to actual needs and are not specifically limited in this application.

[0030] The angle θ1 between the side wall of the second hopper 62 and the height direction Z of the discharge device 6 is 15°-35°. The angle θ1 can be the angle between the first side wall 6231 and the height direction Z of the discharge device 6, or the angle θ1 can be the angle between the second side wall 6232 and the height direction Z of the discharge device 6. In this way, on the one hand, the powder falling on the side wall of the second hopper 62 can slide down by itself under the action of gravity, avoiding accumulation on the second hopper 62, and the smaller collision angle can also reduce the dust generated when the powder collides with the side wall of the second hopper 62. On the other hand, the second end of the second hopper 62 can form a sufficient barrier to the first hopper 61, preventing dust from floating out of the accommodating chamber 611. The specific value of the angle θ1 between the side wall of the second hopper 62 and the height direction Z of the discharge device 6 can be set according to actual needs and is not specifically limited in this application. For example, the angle θ1 can be 15°, 16°, 18°, 20°, 25°, 30°, 35°, etc. In some embodiments, the inner wall of the first hopper 61 and / or the second hopper 62 is mirror-polished to prevent powder from accumulating on the inner wall of the first hopper 61 and / or the second hopper 62.

[0031] An opening 6211 is provided at the first end portion 621. The opening 6211 is arranged opposite to the feed port 6221. A sidewall of the second hopper 62 is provided with a bypass opening 6212 at a position outside the first hopper 61. The bypass opening 6212 is provided on the first sidewall 6231. The bypass opening 6212 is communicated with the opening 6211. The opening direction of the bypass opening 6212 can be set perpendicular to the opening direction of the opening 6211. The bypass opening 6212 is used to bypass the ton bag so that the ton bag can be moved from the side of the second hopper 62 to the second hopper 62, thereby reducing the overall height of the self-unpacking device 100.

[0032] Along the height direction Z of the discharge device 6, the height of the first hopper 61 is greater than the height of the second hopper 62. In a direction perpendicular to the height direction Z of the discharge device 6, the length and width of the first hopper 61 are smaller than the length and width of the second hopper 62. The height of the first hopper 61 is greater than the length and width of the first hopper 61. This ensures that the accommodating chamber 611 has sufficient space to accommodate falling powder, while also reducing the floating space for dust in the accommodating chamber 611. This allows the dust collection structure 63 described below to quickly absorb dust in the accommodating chamber 611, preventing it from drifting into the second hopper 62. Both the first hopper 61 and the second hopper 62 can be roughly constructed in a frustum, cone, or other shape.

[0033] The unloading device 6 also includes a dust suction structure 63. A dust suction port 6111 connected to the accommodating chamber 611 is provided on the side wall of the first hopper 61. The dust suction structure 63 is arranged at the dust suction port 6111. In this embodiment, on the one hand, the second hopper 62 is used to block the dust, and on the other hand, the suction effect of the dust suction structure 63 forms a negative pressure in the accommodating chamber 611, forming an airflow flowing into the accommodating chamber 611 at the feed port 6221. This airflow blows the dust in the accommodating chamber 611 away from the second hopper 62, and brings the dust generated by the collision of the powder and the second hopper 62 into the accommodating chamber 611. Therefore, the combined action of the second hopper 62 and the dust suction structure 63 effectively prevents the dust from floating out of the accommodating chamber 611. A dust suction channel 630 is provided in the dust suction structure 63. The dust suction channel 630 is connected to the dust suction port 6111.

[0034] Multiple dust collection structures 63 are provided. Multiple dust collection structures 63 are spaced apart and arranged along the circumference of the first hopper 61. The number of dust collection structures 63 can be set based on actual needs and is not specifically limited in this application. For example, in this embodiment, two dust collection structures 63 are provided, and the two dust collection structures 63 are arranged opposite each other. Dust collection ports 6111 are respectively provided on two opposing side walls of the first hopper 61.

[0035] In some embodiments, the dust suction structure 63 has a back-blowing function. When the dust suction structure 63 performs back-blowing, the filtered powder can be transported back to the accommodating chamber 611 along the dust suction channel 630. In this way, on the one hand, the service life of the dust suction structure 63 can be improved. On the other hand, the powder returns to the accommodating chamber 611 after back-blowing, which can avoid waste of powder.

[0036] The dust suction channel 630 of the dust suction structure 63 is inclined toward the direction close to the second hopper 62 to reduce the angle between the dust suction direction of the dust suction structure 63 and the floating direction of the dust, thereby improving the dust adsorption effect of the dust suction structure 63 on the dust and reducing the amount of dust. The dust suction direction of the dust suction structure 63 is the outflow direction of the gas when it flows out from the dust suction port 6111. For example, in this embodiment, the dust suction channel 630 is arranged to extend along a straight line. The dust suction direction of the dust suction structure 63 is the extension direction of the dust suction channel 630. The angle between the extension direction of the dust suction channel 630 and the height direction Z of the discharge device 6 is greater than the angle between the side wall of the first hopper 61 and the height direction Z of the discharge device 6. In some embodiments, the dust suction channel 630 can be extended along a curve, and the dust suction direction of the dust suction structure 63 is the tangent direction of the connection between the dust suction channel 630 and the dust suction port 6111.

[0037] In some embodiments, along the extension direction of the dust suction channel 630, the cross-sectional area of ​​the dust suction channel 630 near the dust suction port 6111 is smaller than the cross-sectional area of ​​the dust suction channel 630 away from the dust suction port 6111. In this way, the airflow can have a higher flow rate near the dust suction port 6111 to improve the suction capacity of the dust suction structure 63.

[0038] Along the height direction Z of the discharge device 6, the dust suction port 6111 is located on the side wall of the first hopper 61, near the feed port 6221. This allows the dust suction structure 63 to more effectively absorb dust near the feed port 6221, preventing dust from drifting into the second hopper 62. Along the height direction Z of the discharge device 6, the distance between the dust suction port 6111 and the end of the first hopper 61 closer to the second hopper 62 is shorter than the distance between the dust suction port 6111 and the end of the first hopper 61 farther from the second hopper 62.

[0039] Along the height direction Z of the discharge device 6, the side wall of the dust suction port 6111 away from the second hopper 62 is located on the side of the feed port 6221 away from the second hopper 62. Along the height direction Z of the discharge device 6, the height of the lower end of the dust suction port 6111 is lower than the height of the feed port 6221, so that the airflow formed between the feed port 6221 and the dust suction port 6111 is inclined in a direction away from the second hopper 62, that is, inclined downward, so that the dust driven by the airflow floats downward, reducing the dust floating toward the feed port 6221 and improving the dust removal effect. For example, along the height direction Z of the discharge device 6, the feed port 6221 can be located between the side wall of the dust suction port 6111 away from the second hopper 62 and the side wall close to the second hopper 62. Among them, along the height direction Z of the discharge device 6, the distance between the feed port 6221 and the side wall of the dust suction port 6111 away from the second hopper 62 is greater than the distance between the feed port 6221 and the side wall close to the second hopper 62.

[0040] In some embodiments, the unloading device 6 further includes an aggregate structure 64. A discharge port 6112 is provided at one end of the first hopper 61 away from the second hopper 62. The aggregate structure 64 is connected to the discharge port 6112. The aggregate structure 64 is used to collect the powder material that falls into the accommodating chamber 611 and transfer it to other equipment. In some embodiments, the dust suction structure 63 is also used to transport the sucked powder material to the aggregate structure 64. In some embodiments, the dust suction structure 63 can transport a portion of the sucked powder material back to the accommodating chamber 611 through the dust suction channel 630, and transport the other portion to the aggregate structure 64. In some embodiments, the dust suction structure 63 transports the powder material back to the accommodating chamber 611 through the dust suction channel 630 in one working mode, and transports the powder material to the aggregate structure 64 in another working mode. In some embodiments, an inspection port is provided on the side wall of the first hopper 61 to facilitate maintenance of the unloading device 6.

[0041] Please also refer to Figure 2 and Figure 3 , Figure 3 It is a structural schematic diagram of the cutting structure 5 provided in an embodiment of the present application. The cutting structure 5 includes a cutting member 51, a mounting structure 52 and a lifting member 56. The lifting member 56 is installed in the first hopper 61. The cutting member 51 is connected to the lifting member 56. The cutting member 51 is mounted on the mounting structure 52, and the mounting structure 52 is connected to the lifting member 56. The lifting member 56 is used to drive the cutting member 51 to move relative to the first hopper 61 so that the cutting member 51 cuts the ton bag. A pointed tip is provided on the cutting member 51 to facilitate the cutting member 51 to puncture the ton bag, reduce the difficulty of cutting, and improve the smoothness of the incision of the ton bag. The automatic unpacking equipment 100 also includes a fixed bracket 566. The fixed bracket 566 is used to fix the cutting structure 5 to the first hopper 61.

[0042] In some embodiments, a ventilation duct is provided in the mounting structure 52. The mounting structure 52 is provided with an air outlet 5202 connected to the ventilation duct at a position close to the cutting member 51. The ventilation duct is used to be connected to the air supply structure, and the air supply structure is used to pump gas into the ventilation duct. After the cutting member 51 cuts the ton bag, the air outlet 5202 on the mounting structure 52 can blow air into the ton bag. The gas can improve the fluidity of the powder and maintain a positive pressure in the ton bag, thereby increasing the falling speed of the powder, and can blow off the powder attached to the inner wall of the ton bag to prevent the powder from remaining in the ton bag. The number of air outlets 5202 on each mounting structure 52 can be specifically set according to actual needs and is not specifically limited in this application. For example, the air outlets 5202 on each mounting structure 52 can be set to 1, 2, 3, 4, 5, and so on.

[0043] Multiple mounting structures 52 are provided. The cutting element 51 is arranged in a circular ring shape, with multiple mounting structures 52 spaced apart along the circumference of the cutting element 51. The air outlet holes 5202 on each mounting structure 52 align their outlet direction parallel to the tangent line of the cutting element 51 at the connection between the mounting structure 52 and the cutting element 51. This allows the air outlet holes 5202 on the multiple mounting structures 52 to collectively blow air into the ton bag, creating a swirling airflow within the bag. This improves the fluidity of the powder and more thoroughly removes any powder adhering to the bag's inner walls.

[0044] In some embodiments, the unloading device 6 further includes a bag pushing structure 7. The bag pushing structure 7 is disposed in the second hopper 62. When the automatic unpacking device 100 is unpacking, the bag pushing structure 7 is used to push or tap the four corners of the bottom of the ton bag toward the center of the ton bag, so that all the powder in the ton bag is discharged from the cutout of the ton bag, thereby preventing the powder from remaining in the ton bag.

[0045] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and such modifications or substitutions should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
