[0026] Please refer to Figure 1 , Figure 2 andFigure 3 , Figure 1 is a sectional view of the automatic unpacking equipment 100 provided by the embodiment of the present application, Figure 2 is a schematic view of a partial structure of the cutting device 5 provided by the embodiment of the present application, Figure 3 is a partial sectional view of the cutting device 5 provided by the embodiment of the present application. In the embodiment of the present application, for a clearer description, with reference to Figure 2 , the C-axis direction is defined as the circumferential direction of the cutting device 5, the R-axis is defined as the radial direction of the cutting device 5, and the Z-axis is defined as the height direction of the cutting device 5. The radial direction R and the height direction Z are perpendicular to each other. The tangent direction of the circumferential direction C is perpendicular to the height direction Z and the corresponding radial direction R, respectively.

[0027] The automatic unpacking equipment 100 is used for unpacking operation on ton bags to take out the materials in the ton bags. The automatic unpacking equipment 100 comprises a cutting device 5 and a discharging device 6. The cutting device 5 is installed in the discharging device 6. The cutting device 5 is used for cutting the ton bags so that the materials in the ton bags flow out from the incision. The discharging device 6 is used for collecting the materials flowing out from the ton bags.

[0028] The cutting device 5 comprises a cutting piece 51 and a mounting seat 54. The cutting piece 51 is provided with a blade part 513. The blade part 513 is used for cutting the ton bags. The mounting seat 54 is detachably connected with the end of the cutting piece 51 away from the blade part 513, so as to reduce the disassembly and assembly difficulty of the cutting piece 51 when the cutting piece 51 is maintained or replaced, and facilitate the maintenance of the cutting device 5. The top of the mounting seat 54 is provided with a guide surface 540. The top of the mounting seat 54 is the side of the mounting seat 54 close to the blade part 513 of the cutting piece 51 along the height direction Z of the cutting device 5. The guide surface 540 is adjacent to the side wall of the cutting piece 51. The end of the guide surface 540 away from the cutting piece 51 is inclinedly arranged toward the direction away from the blade part 513 relative to the end of the guide surface 540 close to the cutting piece 51. When the materials fall, the materials falling on the guide surface 540 can slide along the guide surface 540 under the action of gravity, so that the materials can be prevented from remaining on the cutting device 5, the utilization rate of the materials is improved, and the waste of the materials is avoided.

[0029] Among them, the guide surface 540 is arranged adjacent to the side wall of the cutting piece 51, which can avoid a large gap between the guide surface 540 and the cutting piece 51, and avoid the materials remaining in the gap. It can be understood that, since a mounting gap needs to be left between the cutting piece 51 and the mounting seat 54, a small gap can exist between the guide surface 540 and the cutting piece 51. The guide surface 540 can be provided as two, and the side close to the inner side surface 5121 and the side close to the outer side surface 5122 of the mounting seat 54 are respectively provided with the guide surface 540. The two guide surfaces 540 are arranged in an eight-shaped manner, so as to fully avoid the materials remaining on the mounting seat 54.

[0030] The guide surface 540 can be configured as a flat surface or a curved surface. For example, the guide surface 540 can be configured as a flat surface to reduce the processing difficulty and cost of the mounting seat 54. In some embodiments, the guide surface 540 can also be configured as a curved surface. The guide surface 540 can be configured as a curved surface that is convex outwardly towards the cutting piece 51 to facilitate the material to slide along the guide surface 540.

[0031] The included angle θ1 between the guide surface 540 and the side wall of the cutting piece 51 is less than 55°, that is, the included angle between the guide surface 540 and the height direction Z. The included angle θ1 less than 55° can facilitate increasing the pushing effect of gravity on the material and facilitate the material to slide along the guide surface 540 by itself. The specific value of the included angle θ1 can be set according to actual needs, which is not limited in the present application. For example, the included angle θ1 can be, but is not limited to, 55°, 50°, 45°, 40°, or 30°.

[0032] The mounting seat 54 includes a seat body 541 and a locking piece 5414. The locking piece 5414 is used to fixedly connect the cutting piece 51 and the seat body 541 together. The seat body 541 is provided with a mounting groove 5411. The cutting piece 51 is accommodated in the mounting groove 5411. The locking piece 5414 is used to fix the cutting piece 51 in the mounting groove 5411. The side wall of the seat body 541 is provided with a mounting hole 5412 that communicates with the mounting groove 5411. The cutting piece 51 is provided with a through hole 5113 at a position corresponding to the mounting hole 5412. The locking piece 5414 is arranged in the mounting hole 5412 and the through hole 5113 to fix the cutting piece 51 on the seat body 541.

[0033] In some embodiments, the guide surface 540 and the side wall of the mounting groove 5411 can be transitioned with a rounded corner to facilitate the cutting piece 51 to be inserted into the mounting groove 5411 and to avoid the guide surface 540 and the side wall of the mounting groove 5411 forming a sharp corner to cause a safety hazard to the user.

[0034] In some embodiments, the mounting seat 54 further includes an elastic piece 5417. The elastic piece 5417 is arranged in the mounting hole 5412. The hole wall of the mounting hole 5412 is provided with an abutting portion 5413. The abutting portion 5413 can be configured as an annular protrusion. The elastic piece 5417 is elastically abutted between the abutting portion 5413 and the locking piece 5414. The elastic piece 5417 is used to provide an abutting force for the locking piece 5414 to tightly connect the locking piece 5414 and the seat body 541 and avoid the locking piece 5414 from loosening and falling off from the seat body 541.

[0035] In some embodiments, the locking member 5414 includes a first locking portion 5415 and a second locking portion 5416. The first locking portion 5415 and the second locking portion 5416 are located on opposite sides of the abutting portion 5413. The first locking portion 5415 and the second locking portion 5416 are fixedly connected by threads, clamping, bonding or the like. The second locking portion 5416 abuts the side of the abutting portion 5413 away from the first locking portion 5415. The elastic member 5417 elastically abuts between the first locking portion 5415 and the abutting portion 5413. The first locking portion 5415 passes through the through hole 5113. In some embodiments, the locking member 5414 can be configured as a screw or a bolt, and the locking member 5414 is threadedly connected with the seat body 541.

[0036] Please refer to Figure 2 and Figure 4 , Figure 4 is a partial cross-sectional view of the cutting device 5 provided in some examples of the present application. In some embodiments, the mounting seat 54 includes a seat body 541 and a protective member 542. The seat body 541 is detachably connected with the cutting member 51. The protective member 542 is at least partially located on the top of the seat body 541 and covers the connection between the cutting member 51 and the seat body 541. The top of the protective member 542 is provided with a guide surface 540. In some embodiments, the top of the seat body 541 can be provided with the guide surface 540, so that the shape of the seat body 541 corresponds to that of the protective member 542, avoiding structural interference and making the structure of the mounting seat 54 compact.

[0037] In some embodiments, the protective member 542 can be configured as a protective cover, and the seat body 541 is located in a receiving space 5420 in the protective member 542. The seat body 541 can be wrapped by the protective member 542 to avoid material remaining at the connection between the seat body 541 and the cutting member 51 and to avoid the locking member 5414 being blocked by the material and unable to move relative to the seat body 541.

[0038] In some embodiments, the protective member 542 can be configured as a wedge-shaped block provided on the seat body 541, and the inclined surface at the top of the protective member 542 is the guide surface 540. In the projection plane perpendicular to the height direction Z of the cutting device 5, the orthographic projection of the protective member 542 covers the orthographic projection of the seat body 541. By blocking and guiding the material by the protective member 542, the material can be prevented from falling on the seat body 541.

[0039] The cutting device 5 further comprises a support 52. The support 52 is connected with the cutting member 51 to fix the cutting member 51. The support 52 is connected with the mounting seat 54. The support 52 is provided with a ventilation pipeline 5201. The support 52 is provided with an air outlet hole 5202 which is connected with the ventilation pipeline 5201 at a position close to the cutting member 51. The ventilation pipeline 5201 is connected with a gas supply structure which is used to pump gas into the ventilation pipeline 5201. In this way, after the ton bag is cut open, the air outlet hole 5202 on the support 52 can blow gas to the ton bag. The gas can improve the flowability of the powder, keep the ton bag in a positive pressure state, improve the falling speed of the powder, and blow off the powder attached to the inner wall of the ton bag to avoid the powder remaining in the ton bag.

[0040] The number of air outlet holes 5202 on each support 52 can be specifically set according to actual needs, which is not specifically limited in the present application. For example, the air outlet hole 5202 on each support 52 can be provided as 1, 2, 3, 4, 5, etc.

[0041] The support 52 is provided as a plurality of supports. The plurality of supports 52 are arranged at intervals along the circumferential direction C of the cutting device 5. The cutting member 51 is annular, and the air outlet direction of the air outlet hole 5202 on each support 52 is parallel to the tangent direction of the cutting member 51 at the connection between the support 52 and the cutting member 51. When the cutting member 51 is a circular ring, the tangent direction of the cutting member 51 at the connection between the support 52 and the cutting member 51 is perpendicular to the radial direction R of the cutting device 5. When the cutting member 51 is a polygonal ring, the tangent direction of the cutting member 51 at the connection between the support 52 and the cutting member 51 is parallel to the extension direction of the corresponding side of the cutting member 51. In this way, the air outlet direction of the air outlet hole 5202 is parallel to the tangent direction of the cutting member 51, and the air outlet holes 5202 on the plurality of supports 52 blow air into the ton bag together, which can form a rotating air flow in the ton bag, thereby better improving the flowability of the powder and more thoroughly blowing off the powder attached to the inner wall of the ton bag.

[0042] The plurality of supports 52 are arranged at equal intervals along the circumferential direction C of the cutting device 5 to improve the stability of the support 52 to the cutting member 51. The number of supports 52 can be specifically set according to actual needs, which is not specifically limited in the present application. For example, the support 52 can be provided as 3, 4, 5, 6, etc.

[0043] The cutting device 5 further comprises a connecting seat. The end of the support 52 away from the mounting seat 54 is connected to the connecting seat. The connecting seat is provided with a gas storage cavity. The gas storage cavity is in communication with the air passage 5201 of the support 52. In this way, the gas outlet pressure and the gas outlet flow rate of the gas outlet hole 5202 on each support 52 can be consistent or similar through the pressure equalization effect of the gas storage cavity, thereby improving the uniformity of the blowing at each position in the ton bag and avoiding uneven stress on the ton bag and the occurrence of deflection.

[0044] The gas outlet hole 5202 is located outside the accommodation space 5420. The support 52 extends into the accommodation space 5420 and is connected to the bottom of the seat body 541. In some embodiments, the part of the support 52 extending into the accommodation space 5420 is provided with a communication hole 5203. The communication hole 5203 communicates the air passage 5201 and the accommodation space 5420. The communication hole 5203 is used to blow air into the accommodation space 5420 to maintain a positive pressure in the accommodation space 5420, so as to prevent material from entering the accommodation space 5420 from the gap between the protective piece 542 and the cutting piece 51. In addition, blowing air into the gap between the protective piece 542 and the cutting piece 51 can also blow off the material on the protective piece 542, thereby avoiding material residues.

[0045] In some embodiments, the protective piece 542 is provided with an inclined surface 5421 away from the blade 513 of the cutting piece 51. The end of the inclined surface 5421 away from the cutting piece 51 is inclined toward the direction close to the blade 513 relative to the end of the inclined surface 5421 close to the cutting piece 51. In this way, through the guiding effect of the inclined surface 5421, when the cutting device 5 exits from the ton bag, the protective piece 542 and the ton bag can be prevented from being hooked, which is beneficial to the exit of the cutting device 5 from the ton bag.

[0046] Please refer to Figure 5 , Figure 5 is a partial cross-sectional view of the cutting device 5 provided in another example of the present application. Figure 5 The embodiment shown is similar to the embodiment shown in Figure 4 The difference is that the mounting seat 54 further comprises a sealing piece 543. The sealing piece 543 abuts between the protective piece 542 and the cutting piece 51. The sealing piece 543 is used to seal the gap between the protective piece 542 and the cutting piece 51 to prevent material from entering the inside of the protective piece 542. The sealing piece 543 can be configured as a sealing ring, a sealing gasket, etc. In some embodiments, the part of the support 52 extending into the accommodation space 5420 is provided with a communication hole 5203 to maintain a positive pressure in the accommodation space 5420 and improve the sealing effect of the sealing piece 543 on the protective piece 542 and the cutting piece 51. In some embodiments, the part of the support 52 extending into the accommodation space 5420 can not be provided with a communication hole 5203 to reduce the processing difficulty and cost of the support 52.

[0047] In some embodiments, the cutting device 5 further comprises a blowing member. A blowing pipe is arranged in the blowing member. The blowing member is connected with the support member 52. The blowing pipe is in communication with the air pipe 5201. The blowing member is provided with a blowing port. The blowing port is arranged towards the guide surface 540. In this way, the material falling on the guide surface 540 can be blown off by blowing the guide surface 540 by the blowing member, so as to accelerate the sliding speed of the material and fully avoid the problem of material residue.

[0048] The blowing port can be arranged at an angle with the guide surface 540, so as to facilitate the airflow blown out to push the material to slide along the guide surface 540.

[0049] Please refer to Figure 1 and Figure 2 The cutting member 51 is provided with at least one hollow hole 5111. On the one hand, the mass of the cutting member 51 can be reduced, so as to make the cutting device 5 lightweight. On the other hand, the material can also flow out along the hollow hole 5111 during falling, so as to reduce the blockage of the cutting member 51 to the material and improve the falling speed. On the other hand, the hollow hole 5111 can also provide a holding point to facilitate the taking and placing of the cutting member 51. The number of the hollow hole 5111 can be set to be multiple. The multiple hollow holes 5111 are arranged at intervals along the circumferential direction C of the cutting device 5.

[0050] The hole wall 5112 of the hollow hole 5111 away from the blade part 513 is arranged at an angle with the side wall of the cutting member 51, i.e. the hole wall 5112 is arranged at an angle with the height direction Z of the cutting device 5. The hole wall 5112 can be inclined towards the direction away from the blade part 513. In this way, when the material falls on the hole wall 5112, the material will slide along the hole wall 5112 under the action of gravity, so as to avoid the material remaining on the hole wall 5112. The hole wall 5112 can be configured as a plane or a curved surface. In some embodiments, the hole wall 5112 can also be configured as a folded surface. The hole wall 5112 comprises two side surfaces connected with each other, the two side surfaces are arranged at an angle and protrude towards the direction close to the blade part 513. In some embodiments, the hole wall 5112 can also be configured as a curved surface. The curved surface can be arranged to protrude towards the direction of the blade part 513, or the curved surface can also be curved towards the direction away from the blade part 513.

[0051] The cutting device 5 further comprises a flow guide 55. The flow guide 55 is clamped on the connecting seat, so as to simplify the fixing mode of the flow guide 55, avoid the flow guide 55 being connected with the connecting seat through screws, thus avoiding the problem that the screws are loosened after long time use and fall into the powder, and reducing the installation difficulty of the flow guide 55. The side of the flow guide 55 away from the connecting seat is in a conical shape and protrudes away from the connecting seat. The flow guide 55 can be in a pyramid shape or a conical shape. The flow guide 55 is used for guiding the powder when the powder falls, so that the powder slides along the conical surface of the flow guide 55, reduces the impact of the powder on the connecting seat, in addition, the flow guide 55 can also crush the caked powder, and through the shielding effect of the flow guide 55, the powder can also be prevented from accumulating at the connecting position of the support 52 and the connecting seat.

[0052] The cutting device 5 further comprises a lifting structure 56. The connecting seat is connected with the lifting structure 56. The lifting structure 56 is used for driving the connecting seat to move along the height direction Z of the cutting device 5, and the connecting seat drives the support 52 to move together with the cutting piece 51, so that the cutting piece 51 approaches or moves away from the ton bag.

[0053] The automatic unpacking equipment 100 further comprises a discharging device 6. The cutting device 5 is installed in the discharging device 6. The discharging device 6 is used for collecting the powder flowing out of the ton bag. The discharging device 6 comprises a first hopper 61 and a second hopper 62. The second hopper 62 is arranged above the first hopper 61. The first hopper 61 is provided with a containing cavity 611. The lower end of the second hopper 62 extends into the containing cavity 611 and is spaced apart from the side wall of the first hopper 61. The lower end of the second hopper 62 is provided with a feeding port 6221. The cutting device 5 is installed in the first hopper 61 and extends from the feeding port 6221 into the second hopper 62. The automatic unpacking equipment 100 further comprises a fixing support 566. The fixing support 566 is used for fixedly connecting the cutting device 5 and the first hopper 61 together. When the automatic unpacking equipment 100 is unpacking, the hooking assembly of the automatic unpacking equipment 100 moves the ton bag into the second hopper 62, the lifting structure 56 drives the cutting piece 51 to cut the ton bag, the powder flows out of the cut of the ton bag and falls into the containing cavity 611 through the feeding port 6221.

[0054] The discharging device 6 further comprises a collecting device 64 connected to the bottom of the first hopper 61. The collecting device 64 is used to collect the powder falling into the accommodating cavity 611 and transfer the powder to other devices. The discharging device 6 further comprises a dust suction structure 63. A dust suction port 6111 is formed on the sidewall of the first hopper 61. The dust suction structure 63 is arranged at the dust suction port 6111. The dust suction structure 63 is used to filter the dust in the accommodating cavity 611. It can be understood that dust will be generated during the falling of the powder. In the present embodiment, the dust is blocked by the second hopper 62, and the suction of the dust suction structure 63 forms a negative pressure in the accommodating cavity 611, so that the dust can be effectively prevented from floating out of the accommodating cavity 611. The dust suction structure 63 is further used to deliver the filtered powder back into the accommodating cavity 611 or into the collecting device 64.

[0055] The automatic unpacking device 100 further comprises a bag pushing device 7. The bag pushing device 7 is arranged in the second hopper 62. When the automatic unpacking device 100 unpacks, the bag pushing device 7 is used to push or pat the four corners of the bottom of the ton bag towards the center of the ton bag, so that all the powder in the ton bag is discharged from the cut of the ton bag, and the powder is prevented from remaining in the ton bag.

[0056] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be covered in the protection scope of the present application.
