For example, "fix" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0058] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0059] The present invention provides a ton bag anti-dumping device, which includes a loading platform 20, a grabbing assembly 30 and a plurality of bag protection assemblies 10. The grabbing assembly 30 is movably arranged above the loading platform 20, and the grabbing assembly 30 is used to fix the ton bag placed on the loading platform 20; the plurality of bag protection assemblies 10 are arranged at intervals along the edge of the loading platform 20, and the bag protection assembly 10 can move toward or away from the side of the loading platform 20; wherein, when the bag protection assembly 10 moves toward the side close to the loading platform 20, it abuts against the ton bag placed on the loading platform 20; or when the bag protection assembly 10 moves toward the side away from the loading platform 20, it detaches from the ton bag placed on the loading platform 20.

[0060] The ton bag is grabbed by an external gripping mechanism and placed on the loading platform 20. Because the ton bag is heavy after being filled, the loading platform 20 can be made of a strong material, such as steel. Referring to Figure 2 , the mounting frame 21 is connected by multiple crossbeams to form a rectangular shape. A cross plate can be provided on the top surface for support. Detection components 22, such as pressure sensors, can be mounted on the crossbeams of the mounting frame 21 to measure pressure or the weight of the ton bag.

[0061] The detection component 22 can be connected to an external feeding component. When the material in the ton bag reaches a preset weight, the feeding into the ton bag is stopped, thereby realizing automatic control and improving convenience of use.

[0062] In this embodiment, the fixing frame 21 is rectangular in shape to accommodate rectangular ton bags. A bag protection assembly 10 is positioned at each of the four corners of the fixing frame 21. Referring to Figure 1 , when the bag protection assembly 10 moves toward the fixing frame 21, it abuts against the corners of the ton bag placed on the fixing frame 21. The four bag protection assemblies 10 abut against the four corners of the ton bag, thereby supporting the ton bag from four directions and preventing it from tipping over.

[0063] It can be understood that the shape of the fixing frame 21 can also be adjusted according to the shape of the ton bag, and the position of the bag protection assembly 10 can also be adjusted.

[0064] In addition, the detection member 22 can also be in communication with the bag protection assembly 10. When pressure is detected on the fixing frame 21, it indicates that the ton bag is grabbed onto the fixing frame 21. Thus, the bag protection assembly 10 is automatically controlled to move toward the fixing frame 21.

[0065] The grab assembly 30 can be raised and lowered. Before use, the position of the grab assembly 30 is adjusted so that when the grab assembly 30 moves to the top, it does not interfere with the external grab mechanism, thereby avoiding blocking the moving path of the ton bag.

[0066] After a ton bag is placed on the loading platform 20, the gripping assembly 30 descends. By adjusting the stroke of the gripping assembly 30, it is precisely positioned to reach the top opening of the ton bag, thereby securing the opening. This ensures that the feeding mechanism can smoothly deliver material from the opening into the ton bag. The gripping assembly 30 works in conjunction with the bag retaining assembly 10 to secure the top and bottom of the ton bag, enhancing its anti-tip effect.

[0067] In the technical solution of the present invention, the grabbing assembly 30 is used to grab the ton bag and place it on the loading platform 20 to wait for loading. A plurality of the bag protection assemblies 10 are provided at the edge of the loading platform 20. The bag protection assemblies 10 can extend toward the side close to the loading platform 20 so as to abut against the ton bag placed on the loading platform 20, thereby providing a support point for the ton bag and effectively preventing the ton bag from tipping over during the loading process.

[0068] Specifically, the bag protection assembly 10 includes a bracket 11, a first driving member 12 and a blocking structure 13. The bracket 11 is arranged at the edge of the loading platform 20; the first driving member 12 is arranged on the bracket 11; the blocking structure 13 is arranged on the first driving member 12, and the driving member is used to drive the blocking structure 13 to move toward or away from the side of the loading platform 20. When the blocking structure 13 moves toward the side close to the loading platform 20, it abuts against the ton bag placed on the loading platform 20.

[0069] The bracket 11 can be installed at the edge of the fixing frame 21 or outside the edge of the fixing frame 21 .

[0070] The first driving member 12 is mounted on the bracket 11 . The first driving member 12 may be a cylinder, which connects the blocking structure 13 with its piston rod. When the piston rod is extended or retracted, the blocking structure 13 can be driven to extend or retract.

[0071] It can be understood that the stroke of the first driving member 12 can be set to extend so as to enable the blocking structure 13 to abut against the ton bag placed on the fixing frame 21.

[0072] The mounting position of the bracket 11 is adjusted so that when the first driving member 12 is retracted to the shortest position, the blocking structure 13 does not block the movement path of the external grabbing mechanism to grab the ton bag, thereby ensuring that the ton bag can be smoothly placed on the fixing frame 21.

[0073] The shape of the blocking structure 13 can be a straight plate, a curved plate, etc., as long as the surface of the blocking structure 13 can fit the outer side of the ton bag.

[0074] In this embodiment, the bottom of the ton bag is in a cubic shape, and its top corners are right angles or rounded corners. Therefore, in order to improve the support stability of the blocking structure 13, two baffles are connected. The first baffle 131 and the second baffle 132 are respectively attached to the two adjacent outer sides of the ton bag, thereby providing support in two directions.

[0075] Specifically, referring to FIG. 3 , one side edge of the first baffle 131 and one side edge of the second baffle 132 are connected via a hinge 15 , so that the first baffle 131 and the second baffle 132 can rotate relative to each other.

[0076] The first driving member 12 is connected to one of the baffles, driving it to mate with one side of the ton bag. A second driving member 14 is mounted on this baffle. This second driving member 14 can also be a pneumatic cylinder, with its piston rod connected to the hinge 15. This allows the second driving member 14 to rotate the other baffle relative to the hinge when it expands or contracts. Therefore, once the baffle connected to the first driving member 12 mates with the outside of the ton bag, the second driving member 14 rotates the other baffle until it mates with the other side of the ton bag, or until the angle between the first baffle 131 and the second baffle 132 reaches 90 degrees.

[0077] When the first driving member 12 drives one of the baffles to retract, the second driving member 14 simultaneously drives the other baffle to rotate, so that the angle between the first baffle 131 and the second baffle 132 is 180°, that is, the two baffles are connected into a plane, thereby avoiding the situation where the other baffle collides with the ton bag when the first driving member 12 drives the baffle to fit the ton bag, resulting in position displacement or failure to fit normally.

[0078] The hinged member 15 includes a first connecting part 151, a second connecting part 152 and a driving part 153. One end of the first connecting part 151 is connected to the first baffle 131, the other end of the first connecting part 151 is hinged to one end of the second connecting part 152, and the other end of the second connecting part 152 is connected to the second baffle 132; one end of the driving part 153 is connected to the second baffle 132, and the other end is connected to the driving end of the second driving member 14.

[0079] The first connecting portion 151 and the second connecting portion 152 are connected via a pin shaft to achieve rotation.

[0080] A protruding driving portion 153 is additionally provided on the second baffle 132 . One end of the driving portion 153 extends out of the surface of the second baffle 132 so as to be connected to the second driving member 14 .

[0081] When the second driving member 14 is extended or retracted, the driving portion 153 is pushed to move, and with the cooperation of the first connecting portion 151 and the second connecting portion 152 , the second baffle 132 is rotated relative to the first baffle 131 .

[0082] Furthermore, the grabbing assembly 30 includes a lifting drive member 31, a positioning mechanism 33, a clamping mechanism 32 and a limiting rod 34, the lifting drive member 31 is arranged above the loading platform 20; the positioning mechanism 33 is movably arranged on the lifting drive member 31; the clamping mechanism 32 is arranged at the bottom of the positioning mechanism 33; one end of the limiting rod 34 is connected to the clamping mechanism 32, and the other end is passed through the positioning mechanism 33, and a limiting plate 35 is provided on the end of the limiting rod 34 away from the clamping mechanism 32; wherein, when the positioning mechanism 33 moves to abut against the limiting plate 35, the clamping mechanism 32 is driven to move synchronously by the limiting rod 34.

[0083] 4 , the lifting drive member 31 may be a linear module. The diameter of the through hole on the positioning mechanism 33 for passing the limiting rod 34 is smaller than the size of the limiting piece 35 .

[0084] When the lifting drive member 31 drives the positioning mechanism 33 to rise until the positioning mechanism 33 abuts against the limiting piece 35 , the limiting rod 34 is driven to rise, and the limiting rod 34 drives the clamping mechanism 32 connected to the bottom to rise synchronously.

[0085] When the lifting drive member 31 drives the positioning mechanism 33 to descend until the positioning mechanism 33 abuts against the clamping mechanism 32 , the lifting drive member 31 pushes the clamping mechanism 32 to descend synchronously.

[0086] Before the ton bag reaches the fixing frame 21 , the positioning mechanism 33 and the clamping mechanism 32 move to the top to avoid blocking the ton bag.

[0087] After the ton bag reaches the fixing frame 21 , the positioning mechanism 33 descends and extends into the bag opening of the ton bag, and the clamping mechanism 32 shapes the bag opening of the ton bag.

[0088] By cooperating with the grabbing assembly 30 and the bag protecting assembly 10 , the top and bottom of the ton bag are fixed, thereby improving the anti-dumping effect.

[0089] It is understood that the ton bag can be arranged by external equipment before being moved to the fixing rack 21, and moved to the fixing rack 21 while maintaining the shape shown in FIG1. ​​This facilitates the operation of the positioning mechanism 33 and the clamping mechanism 32.

[0090] Specifically, please refer to Figure 5. The clamping mechanism 32 includes a bidirectional linear motion module 321, two clamping arms 322 and an adsorption component 323. The two clamping arms 322 are respectively arranged on the two driving ends of the bidirectional linear motion module 321. The bidirectional linear motion module 321 is used to drive the two clamping arms 322 to move toward or away from each other; the adsorption component 323 is arranged on the clamping arm 322.

[0091] The bidirectional linear motion module 321 can drive the two clamping arms 322 to move toward each other or away from each other.

[0092] When the ton bag is placed before the fixing frame 21, the two clamping arms 322 are controlled to move away from each other and open; when the ton bag is placed after the fixing frame 21, the lifting drive member 31 is driven down, and the two clamping arms 322 move toward each other, thereby fitting the outer side of the bag opening.

[0093] The clamping arm 322 is provided with a suction piece 323 for sucking the outer side surface of the bag opening tightly, thereby shaping the bag opening and preventing the bag opening from being deformed during the loading process.

[0094] 5 , in this embodiment, the opening of the ton bag is cylindrical, and the adsorption member 323 adopts an arc-shaped structure, so that it can better fit the opening of the ton bag. The adsorption member 323 can be connected to an external vacuum source to generate adsorption negative pressure.

[0095] Please refer to Figure 6, the positioning mechanism 33 includes a mounting plate 331 and a positioning cylinder 332. The mounting plate 331 is movably set on the lifting drive member 31, and the mounting plate 331 has a limiting hole for the limiting rod 34 to pass through; the positioning cylinder 332 is set on the mounting plate 331, and the bottom of the positioning cylinder 332 extends toward the clamping mechanism 32; wherein, when the lifting drive member 31 drives the mounting plate 331 to move toward the side of the clamping mechanism 32 until it abuts against the clamping mechanism 32, the bottom of the positioning cylinder 332 is flush with the clamping mechanism 32.

[0096] The diameter of the limiting hole is smaller than the size of the limiting piece 35 , so when the mounting plate 331 rises to abut against the limiting piece 35 , it pushes the limiting rod 34 to rise.

[0097] The diameter of the positioning cylinder 332 is adapted to the opening diameter of the ton bag and can be slightly smaller, allowing for more accurate insertion into the bag opening during descent. The top of the positioning cylinder 332 can be docked with an external feeding device, which feeds material into the positioning cylinder 332, where it enters the ton bag, preventing leakage.

[0098] During assembly, the height of the clamping mechanism 32 is adjusted so that when the positioning cylinder 332 is lowered to its lowest position, the bottom of the positioning cylinder 332 is flush with the position of the clamping device. This allows the clamping mechanism 32 to cooperate with the positioning cylinder 332 to press against the outer surface of the bag opening when clamping the bag opening, ensuring that the adsorbent 323 fits the bag better.

[0099] Furthermore, the positioning mechanism 33 further includes an inflation bag 36 and an air hammer 37 . The inflation bag 36 is disposed at the bottom of the positioning cylinder 332 ; the air hammer 37 is disposed at the top of the positioning cylinder 332 .

[0100] When the positioning cylinder 332 is inserted into the opening of the ton bag, air is inflated into the bag-expanding airbag 36, causing the bag-expanding airbag 36 to expand. The expansion of the bag-expanding airbag 36 opens the opening of the ton bag, allowing the bag opening to better fit the adsorbent 323.

[0101] The inflatable bag 36 can be connected to an external air source device to achieve inflation of the bag. Within a certain period of time after inflation, the air in the inflatable bag 36 can be extracted so that the positioning cylinder 332 can be better separated from the ton bag when the positioning cylinder 332 rises.

[0102] The air hammer 37 is fixed on the top of the positioning cylinder 332. When the air hammer 37 is turned on, the positioning cylinder 332 can be vibrated to prevent excessive accumulation of materials at the top of the positioning cylinder 332 and cause blockage.

[0103] Furthermore, the ton bag anti-dumping device also includes a lower support frame 42 and an upper support frame 41, the upper support frame 41 is movably arranged on the lower support frame 42, the loading platform 20 is arranged on the lower support frame 42, and the grabbing assembly 30 is arranged on the upper support frame 41.

[0104] Referring to Figure 7 , for ease of movement and transport, the aforementioned equipment can be mounted on a bracket 11, specifically comprising an upper support frame 41 and a lower support frame 42. The heights of the upper and lower support frames 41 and 42 are adjustable. The loading platform 20 and the bag protection assembly 10 are mounted on the lower support frame 42, while the gripping assembly 30 is mounted on the upper support frame 41. Adjusting the height difference between the loading platform 20 and the gripping assembly 30 allows for adjustment.
