[0036] The following first briefly introduces the basic concepts involved in the embodiments of this application.

[0037] Please also refer to Figures 1 to 3 , Figure 1 This is a structural schematic diagram from a first perspective of the ton bag hanging device 100 provided in an embodiment of the present application, omitting the sealing plate 713; Figure 2 yes Figure 1 The cross-sectional view of the ton bag suspension device 100 in the punctured state, Figure 3 yes Figure 1A cross-sectional view of a ton bag suspension device 100 in a suspended state is shown in FIG. An embodiment of the present application provides a ton bag suspension device 100. The ton bag suspension device 100 includes a mounting plate 10, a first drive mechanism 20, a connecting rod mechanism 30, and a plurality of piercing rods 40. The first drive mechanism 20 is disposed on the mounting plate 10. The connecting rod mechanism 30 is in transmission connection with the first drive mechanism 20. The plurality of piercing rods 40 are respectively hingedly connected to the connecting rod mechanism 30; the first drive mechanism 20 is configured to drive the connecting rod mechanism 30 to rotate the plurality of piercing rods 40. The angle formed between the extension direction of the piercing rods 40 and the height direction Z of the ton bag suspension device 100 is a first angle α. When the first angle α is less than or equal to a first preset value, the plurality of piercing rods 40 are configured to pierce the ton bag and detach from the ton bag. When the first angle α is greater than or equal to a second preset value, the plurality of piercing rods 40 are configured to suspend the ton bag, and the plurality of piercing rods 40 are arranged to be inclined toward the ton bag relative to the height direction Z of the ton bag suspension device 100.

[0038] The ton bag hanging device 100 provided in the embodiment of the present application is based on the setting of a first driving mechanism 20 to drive the connecting rod mechanism 30 to drive the piercing rod 40 to rotate relative to the height direction Z of the ton bag hanging device 100. When the first angle α is less than or equal to the first preset value, the piercing rod 40 is used to pierce the ton bag and detach the ton bag from the suspension. When the first angle α is greater than or equal to the second preset value, the piercing rod 40 is used to hang the ton bag. The piercing rod 40 is inclined toward the four sides of the ton bag relative to the height direction Z of the ton bag hanging device 100. On the one hand, the piercing rod 40 pierces and hangs the ton bag, and the piercing rod 40 releases the ton bag. On the other hand, the first driving mechanism 20 can drive multiple piercing rods 40 to rotate toward the four sides of the ton bag after the ton bag is pierced, so that multiple piercing rods 40 can open the ton bag, avoiding the problem that the ton bag is easily affected by the deflation of the bag body during the unloading process and the increase of the residual amount of material in the ton bag, facilitating the falling of the material in the ton bag, and improving the unloading rate and unloading effect.

[0039] It should be noted that Figure 1 The purpose is only to schematically describe the arrangement of the mounting plate 10, the first drive mechanism 20, the connecting rod mechanism 30 and the plurality of puncturing rods 40, and is not to make specific limitations on the connection positions, connection relationships and specific structures of the various components. Figure 1 The structure of the ton bag hanging device 100 is only shown in the embodiment of the present application, and does not constitute a specific limitation on the ton bag hanging device 100. In other embodiments of the present application, the ton bag hanging device 100 may include Figure 1 More or fewer components, or combinations of certain components, or different components, such as the ton bag suspension device 100 may also include but are not limited to connecting cables, mounting racks, etc. The term "extension direction of the piercing rod 40" refers to a direction parallel to the central axis of the piercing rod 40.

[0040] The ton bag hanging device 100 is a device for hanging ton bags. The ton bag hanging device 100 has a puncturing state and a hanging state. In the puncturing state, the puncturing rod 40 of the ton bag hanging device 100 can be used to puncture the ton bag. In the hanging state, the puncturing rod 40 of the ton bag hanging device 100 can hang the ton bag. A ton bag is a large-capacity, heavy-duty freight bag used for packaging and transportation, typically used to transport solid goods such as granular materials, powdered materials, and bulk materials. Ton bags are used to carry materials, such as but not limited to battery materials, food materials, pharmaceutical materials, fertilizer materials, construction materials, etc., and the materials carried by ton bags are not limited here. For example, in the embodiment of the present application, the ton bag is used to carry battery materials. Battery materials include but are not limited to positive electrode materials, negative electrode materials, conductive agents, dispersants, etc.; alternatively, various materials can be mixed to form a battery mixture.

[0041] For the accuracy of description, please refer to the direction in this article. Figure 1 For reference, "length direction X" refers to the direction in which the first drive mechanism 20 drives the connecting rod mechanism 30 to translate relative to the mounting plate 10, that is, the left-right direction (where the positive direction of the X axis is left); the term "height direction Z" refers to the direction in which the second drive mechanism 81 of the ton bag hanging device 100 drives the ton bag hanging device 100 and the ton bag suspended by the ton bag hanging device 100 to move up and down, that is, the up and down direction (where the positive direction of the Z axis is up); the term "width direction Y" refers to the direction perpendicular to the length direction X and the height direction Z, that is, the front-to-back direction (where the positive direction of the Y axis is back). Among them, the length direction X, the width direction Y and the height direction Z together constitute the three orthogonal directions of the ton bag hanging device 100. The length direction X, the width direction Y and the height direction Z of the ton bag hanging device 100 can be customized according to the specific structure of the product and the perspective presented in the drawings, and this application does not make specific restrictions. For the convenience of description, the directions such as up, down, left, right, front and back in this application are relative positions and do not constitute a limitation on implementation.

[0042] The first preset value and the second preset value can be set according to factors such as the weight and shape of the ton bag, and are not specifically limited in the embodiment of the present application. For example, the range of the first preset value can be 0°-10°, and the range of the second preset value can be 60°-90°. It can be understood that the smaller the value of the first preset value, the smaller the angle between the extension direction of the puncture rod 40 and the height direction Z of the ton bag suspension device 100 in the puncture state, thereby making it easier for the puncture rod 40 to puncture the ton bag. When the value of the second preset value is larger, the angle between the extension direction of the puncture rod 40 and the height direction Z of the ton bag suspension device 100 in the hanging state is larger, thereby avoiding the risk of the ton bag slipping from the puncture rod 40 and improving the reliability and stability of the puncture rod 40 hanging the ton bag.

[0043] The first angle α is between 0° and 90°. Thus, on the one hand, the rotation angle range of the puncturing rod 40 is increased, allowing the ton bag hanging device 100 to freely switch between the puncturing state and the hanging state, and allowing the puncturing rod 40 to have both puncturing and hanging functions, thereby achieving diversified use functions of the ton bag hanging device 100 and a simple and compact structure. On the other hand, by limiting the rotation angle of the puncturing rod 40, the puncturing rod 40 can be quickly rotated to an appropriate angle according to the required working state, thereby improving the convenience of use of the ton bag hanging device 100. For example, the first angle α can be, but is not limited to, 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, or 90°, etc. When the first angle α is 0° or close to 0°, the extension direction of the piercing rod 40 is parallel to the height direction Z of the ton bag hanging device 100. At this point, the piercing rod 40 is approximately perpendicular to the piercing surface of the ton bag, thereby improving the piercing effect of the piercing rod 40 and reducing the size of the puncture hole in the ton bag, thereby avoiding the problem of tearing caused by a larger puncture hole. This improves the reliability and stability of the piercing rod 40 in subsequent suspending of the ton bag. When the first angle α is 90° or close to 90°, the extension direction of the piercing rod 40 is perpendicular to the height direction Z of the ton bag hanging device 100. At this point, the piercing rod 40 is approximately parallel to the piercing surface of the ton bag, thereby improving the piercing effect of the piercing rod 40 on the ton bag. It is understandable that when the first angle α is greater than 90°, the piercing tip of the piercing rod 40 is more likely to pierce the ton bag again, which can easily cause the ton bag to tear and slide off the piercing rod 40. Of course, in some embodiments, the piercing rod 40 can also pierce the ton bag when the first angle α is greater than 0° and less than or equal to the first preset value, and the piercing rod 40 can also hang the ton bag when the first angle α is greater than or equal to the second preset value and less than 90°. The embodiments of the present application do not make specific limitations.

[0044] Please also refer to Figure 1 and Figure 4 , Figure 4 yes Figure 1A structural diagram of a partial structure of the ton bag hanging device 100 in FIG. In some embodiments, the ton bag hanging device 100 further includes a plurality of swing rods 50. Each piercing rod 40 is hinged to the connecting rod mechanism 30 through a corresponding swing rod 50, and the angle formed by the extension direction of the swing rod 50 and the extension direction of the piercing rod 40 is a second angle β, and the second angle β is an obtuse angle. Thus, on the one hand, the swing rod 50 serves as a transition connection structure between the piercing rod 40 and the connecting rod mechanism 30, thereby improving the structural flexibility of the connecting rod mechanism 30, facilitating installation, and allowing the piercing rod 40 to rotate flexibly in a specified direction; on the other hand, based on the setting that the extension direction of the swing rod 50 is set at an obtuse angle to the extension direction of the piercing rod 40, the swing rod 50 and the piercing rod 40 can effectively disperse the load, reduce the force acting on the connecting rod mechanism 30, protect the connecting rod mechanism 30 from damage, extend the service life, and enable the piercing rod 40 to reduce stress concentration under the weight of the ton bag. , thereby enhancing the stability and durability of the puncture rod 40 structure; on the other hand, by adjusting the position and number of hinges between the puncture rod 40 and the connecting rod mechanism 30 through the swing rod 50, it is possible to avoid excessive concentration of stress at a certain point to a certain extent, thereby reducing the risk of damage to the connecting rod mechanism 30 and the puncture rod 40 due to stress concentration, so that the connecting rod mechanism 30 and the puncture rod 40 can bear the external force more evenly, improve the durability and safety of the structure, and optimize the performance of the integrated structure formed by the connection of the connecting rod mechanism 30 and the puncture rod 40, improve the connection stability and reduce vibration.

[0045] One end of the swing arm 50 is hinged to the connecting rod mechanism 30, and the other end of the swing arm 50 is hinged to the mounting plate 10. Specifically, a pivot seat 11 is provided on the mounting plate 10, and the swing arm 50 is pivotally connected to the pivot seat 11 via a pivot shaft 12, thereby enabling the first drive mechanism 20 to drive the connecting rod mechanism 30 to drive the swing arm 50 and the puncture rod 40 to rotate. In some embodiments, a reinforcement structure 51 is provided at the position of the swing arm 50 corresponding to the pivot seat 11. The reinforcement structure 51 is pivotally connected to the pivot seat 11 via the pivot shaft 12. As a result, the reinforcement structure 51 can enhance the structural strength of the swing arm 50, prevent the swing arm 50 from breaking, and improve the safety of the ton bag suspension device 100.

[0046] In this embodiment, the swinging lever 50 and the puncturing lever 40 are integrally formed, thereby improving the connection strength and reliability between the puncturing lever 40 and the swinging lever 50. Of course, in some embodiments, the swinging lever 50 and the puncturing lever 40 can be provided independently of each other and fixedly connected, thereby facilitating operations such as assembly, disassembly, maintenance, and replacement of the puncturing lever 40 and the swinging lever 50.

[0047] In some embodiments, the swing arm 50 is connected to the puncture rod 40 in a smooth transition. This, on the one hand, reduces stress concentration between the swing arm 50 and the puncture rod 40, extending the service life of the puncture rod 40; on the other hand, improves the strength and stability of the connection between the swing arm 50 and the puncture rod 40.

[0048] Please also refer to Figure 1 and Figure 5 , Figure 5 yes Figure 1 Exploded view of the ton bag hanging device 100 in FIG. In some embodiments, the ton bag hanging device 100 further includes a sliding mechanism 60. The sliding mechanism 60 is slidably disposed on the mounting plate 10 and is connected to the connecting rod mechanism 30. The first driving mechanism 20 is used to drive the connecting rod mechanism 30 and the sliding mechanism 60 to move synchronously. Thus, on the one hand, the sliding mechanism 60 can guide the movement of the connecting rod mechanism 30, thereby improving the smoothness and accuracy of the movement of the connecting rod mechanism 30, and preventing the ton bag suspended by the puncture rod 40 from shaking, thereby ensuring the uniformity of the puncturing position of the ton bag and improving the material unloading rate; on the other hand, the setting of the sliding mechanism 60 can also reduce the friction when the object moves, thereby reducing the driving force required by the first driving mechanism 20 and improving the movement efficiency of the connecting rod mechanism 30. For example, in this embodiment, the first driving mechanism 20 is used to drive the connecting rod mechanism 30 and the sliding mechanism 60 to move synchronously along the longitudinal direction X of the ton bag hanging device 100. Of course, in some embodiments, the first driving mechanism 20 is used to drive the connecting rod mechanism 30 and the sliding mechanism 60 to move synchronously along the width direction Y of the ton bag hanging device 100 or along other directions within the plane where the mounting plate 10 is located. This embodiment of the present application does not make specific limitations.

The first driving mechanism 20 includes a driving member 21 and a transmission member 22. The transmission member 22 is connected to the driving member 21 in a transmission manner and is connected to the sliding mechanism 60 through the connecting rod seat 31. The number of connecting rods 32 corresponds to the number of puncturing rods 40. One end of the connecting rod 32 is hinged to the connecting rod seat 31, and the other end of the connecting rod 32 is hinged to the corresponding puncturing rod 40. Therefore, on the one hand, through the precise cooperation between the transmission member 22 and the sliding mechanism 60, it is ensured that the connecting rod seat 31 drives the connecting rod 32 to move according to the preset path and speed, thereby improving the transmission effect and transmission accuracy of the transmission member 22; on the other hand, each puncturing rod 40 is connected to the corresponding connecting rod 32, thereby increasing the stability of the rotation of the puncturing rod 40 driven by the connecting rod 32 and reducing vibration and shaking.

[0050] Please refer again Figure 2 and Figure 3For example, in this embodiment, when the first angle α is less than or equal to the first preset value, the angle between the extension direction of the connecting rod 32 of the connecting rod mechanism 30 and the extension direction of the swing rod 50 is a third angle γ. When the first angle α is greater than or equal to the second preset value, the angle between the extension direction of the connecting rod 32 of the connecting rod mechanism 30 and the extension direction of the swing rod 50 is a fourth angle δ. For example, in this embodiment, the third angle γ is an acute angle and the fourth angle δ is an obtuse angle. When the first angle α is greater than or equal to the second preset value, the extension direction of the connecting rod 32 of the connecting rod mechanism 30 is parallel to the extension direction of the piercing rod 40, that is, the fourth angle δ is equal to the second angle β. As a result, the force on the connecting rod 32 and the piercing rod 40 is evenly distributed, thereby extending the service life of the ton bag hanging device 100. The extending direction of the connecting rod 32 of the connecting rod mechanism 30 being parallel to the extending direction of the puncture rod 40 means that the central axis of the connecting rod 32 is parallel to the central axis of the puncture rod 40 connected to the connecting rod 32 .

[0051] It should be noted that the term "parallel" refers to the situation where two straight lines on a plane, two planes in space, or a straight line and a plane in space have no common points. The term "perpendicular" refers to the situation where a line on a plane intersects another line at right angles, and the two lines are perpendicular to each other. In the embodiments of this application, descriptions such as "parallel" and "perpendicular" may include situations where approximate parallelism and approximate perpendicularity are caused by processing errors, measurement errors, etc.

[0052] In this embodiment, the connecting rod base 31 includes a first connecting portion 315, a second connecting portion 316, and a third connecting portion 317. The first connecting portion 315, the second connecting portion 316, and the third connecting portion 317 are arranged along the width direction Y of the ton bag hanging device 100. The first connecting portion 315 is connected to the transmission member 22, the second connecting portion 316 is connected to the connecting rod mechanism 30, and the third connecting portion 317 is connected to the sliding mechanism 60. Thus, on the one hand, the arrangement of the first connecting portion 315, the second connecting portion 316, and the third connecting portion 317 along the width direction Y of the ton bag hanging device 100 maximizes the use of available space and avoids space waste. On the other hand, the transmission member 22, the connecting rod mechanism 30, and the sliding mechanism 60 are all connected to the connecting rod base 31, making the integrated structure formed by the connecting rod base 31, the transmission member 22, the connecting rod mechanism 30, and the sliding mechanism 60 more secure and reliable. Furthermore, through reasonable arrangement, the ton bag hanging device 100 can be tightly integrated within a compact space, improving space utilization. Specifically, an articulated seat 3161 is provided at the location of the connecting rod seat 31 corresponding to the second connecting portion 316. The connecting rod mechanism 30 is hingedly connected to the articulated seat 3161 via a hinge shaft 3162, thereby enabling the first drive mechanism 20 to drive the connecting rod 32 to rotate to a predetermined angle relative to the connecting rod seat 31. In some embodiments, a reinforcement structure 51 is also provided at the location of the connecting rod 32 corresponding to the articulated seat 3161. The reinforcement structure 51 is hingedly connected to the articulated seat 3161 via the hinge shaft 3162. Thus, the reinforcement structure 51 enhances the structural strength of the connecting rod 32, preventing breakage of the connecting rod 32 and improving the safety of the ton bag suspension device 100.

[0053] Please refer again Figure 2 and Figure 5For example, in this embodiment, the plurality of puncturing rods 40 include a first puncturing rod 41 and a second puncturing rod 42. The connecting rod seat 31 is provided in two, namely a first base 311 and a second base 312. The plurality of connecting rods 32 include a first connecting rod 321 and a second connecting rod 322. The first base 311 and the second base 312 are each slidably connected to the sliding mechanism 60. One end of the first connecting rod 321 is connected to the first base 311, and the other end of the first connecting rod 321 is hinged to the first puncturing rod 41. One end of the second connecting rod 322 is connected to the second base 312, and the other end of the second connecting rod 322 is hinged to the second puncturing rod 42. The transmission member 22 includes a first transmission part 221 and a second transmission part 222. The first transmission part 221 is fixedly connected to the first base 311, and the second transmission part 222 is fixedly connected to the second base 312. The first base 311 is connected to the first transmission portion 221, the first connecting rod 321, and the first puncturing rod 41 to form a first transmission module 510. The second base 312 is connected to the second transmission portion 222, the second connecting rod 322, and the second puncturing rod 42 to form a second transmission module 520. The driving member 21 is used to drive the first transmission module 510 and the second transmission module 520 in opposite directions, thereby causing the first puncturing rod 41 and the second puncturing rod 42 to rotate in opposite directions. There are multiple first transmission modules 510 and multiple second transmission modules 520, each of which is arranged in a predetermined direction with a spacing between each first transmission module 510 and a corresponding second transmission module 520. Therefore, on the one hand, the first piercing rod 41 and the second piercing rod 42 rotate in opposite directions so that the first piercing rod 41 and the second piercing rod 42 can stretch the ton bag, thereby avoiding the problem that the ton bag is easily affected by the collapse of the bag body during the unloading process, affecting the dropping speed and increasing the residual amount of material in the ton bag, facilitating the falling of the material in the ton bag, and improving the unloading rate and unloading effect; on the other hand, each first piercing rod 41 and the corresponding second piercing rod 42 can rotate synchronously at the same speed, thereby improving the force uniformity of the first piercing rod 41 and the second piercing rod 42, improving the reliability and stability of the piercing rod 40 hanging the ton bag, and extending the service life of the ton bag hanging device 100.

[0054] It should be noted that a preset direction refers to a manually defined direction, for example, any direction within the plane of the mounting plate 10. For example, in this embodiment, the preset direction is parallel to the sliding direction of the sliding mechanism 60. For example, the preset direction may be, but is not limited to, the length direction X or width direction Y of the ton bag suspension device 100, or other directions within the plane of the mounting plate 10.

[0055] The preset direction includes a first direction and a second direction, the first direction intersecting with the second direction, and each first transmission module 510 and the corresponding second transmission module 520 are arranged at intervals along the first direction or the second direction. For example, the first direction is the length direction X of the ton bag hanging device 100, and the second direction is the width direction Y of the ton bag hanging device 100. Of course, the first direction and the second direction can be set according to actual conditions, and this application does not make specific limitations. Multiple first transmission modules 510 and multiple second transmission modules 520 are each arranged at intervals along the length direction X or the width direction Y of the ton bag hanging device 100, that is, all first transmission modules 510 and the corresponding second transmission modules 520 are arranged at intervals along the length direction X or the width direction Y of the ton bag hanging device 100. At this time, the ton bag hanging device 100 can be provided with only one sliding mechanism 60, which improves the compactness of the overall structure of the ton bag hanging device 100, high space utilization, and low cost. For example, in this embodiment, the plurality of first transmission modules 510 and the plurality of second transmission modules 520 are each arranged at intervals along the width direction Y of the ton bag suspension device 100. That is, all the first transmission modules 510 and the corresponding second transmission modules 520 are arranged at intervals along the length direction X of the ton bag suspension device 100. This facilitates assembly of the first transmission modules 510 and the second transmission modules 520, and through reasonable parallel arrangement within a compact space, the ton bag suspension device 100 can be tightly integrated, thereby improving space utilization.

[0056] Of course, in some embodiments, some of the first transmission modules 510 and corresponding second transmission modules 520 are arranged at intervals along the first direction, while the remaining first transmission modules 510 and corresponding second transmission modules 520 are arranged at intervals along the second direction. For example, some of the first transmission modules 510 and some of the second transmission modules 520 are arranged at intervals along the length direction X of the ton bag suspension device 100, while the remaining first transmission modules 510 and some of the second transmission modules 520 are arranged at intervals along the width direction Y of the ton bag suspension device 100. In this case, the ton bag suspension device 100 needs to be equipped with two sliding mechanisms 60, one of which slides in a direction parallel to the length direction X of the ton bag suspension device 100, and the other slides in a direction parallel to the width direction Y of the ton bag suspension device 100, thereby enabling the first transmission modules 510 and some of the second transmission modules 520 in different directions to move in opposite directions. Therefore, multiple first piercing rods 41 and multiple second piercing rods 42 can expand the ton bag in multiple directions within the plane where the mounting plate 10 is located, thereby better achieving the expansion effect of the ton bag, and thus avoiding the problem that the ton bag is easily affected by the collapse of the bag body during the unloading process, affecting the dropping speed and increasing the residual amount of material in the ton bag, facilitating the falling of the material in the ton bag, and improving the unloading rate and unloading effect.

[0057] The driving member 21 includes a translation driver 211 and a screw rod 212 in transmission connection with the translation driver 211. The first transmission portion 221 is provided with a first screw hole 2211 that is threadedly connected to the screw rod 212, and the second transmission portion 222 is provided with a second screw hole 2221 that is threadedly connected to the screw rod 212. The thread direction of the first screw hole 2211 is opposite to the thread direction of the second screw hole 2221. Thus, on the one hand, a translation driver 211 drives the first transmission part 221 and the second transmission part 222 to move in different directions, thereby improving the compactness and connection reliability of each part of the ton bag hanging device 100, saving costs, and realizing that the first base 311 drives the first connecting rod 321 and the first piercing rod 41 hinged to the first connecting rod 321 and the second base 312 drives the second connecting rod 322 and the second piercing rod 42 hinged to the second connecting rod 322 to rotate synchronously at the same speed, thereby improving the force uniformity of the first piercing rod 41 and the second piercing rod 42, improving the reliability and stability of the piercing rod 40 hanging ton bags, and extending the service life of the ton bag hanging device 100; on the other hand, based on the setting that the thread direction of the first screw hole 2211 is opposite to the thread direction of the second screw hole 2221, the first piercing rod 41 and the second piercing rod 42 rotate in opposite directions. In this way, the translation driver 211 can drive the first transmission part 221 and the second transmission part 222 to respectively drive the first piercing rod 41 hinged to the first connecting rod 321 and the second piercing rod 42 hinged to the second connecting rod 322 to rotate in opposite directions, so that the first piercing rod 41 and the second piercing rod 42 can open the ton bag, avoiding the problem that the ton bag is easily affected by the deflation of the bag body during the unloading process and increasing the residual amount of material in the ton bag, facilitating the falling of the material in the ton bag, and improving the unloading rate and unloading effect.

[0058] The first drive mechanism 20 can be configured as, but not limited to, a screw-nut structure. The screw-nut structure is a structure used to convert rotational motion into linear motion. Specifically, the translation driver 211 of the first drive mechanism 20 drives the screw 212 to rotate around the central axis of the screw 212, and the first transmission part 221 and the second transmission part 222 move linearly relative to the screw 212 along the central axis of the screw 212 under the action of the rotation of the screw 212. It can be understood that the screw-nut structure has good positioning accuracy during the transmission process, can reduce energy loss when transmitting force and achieve higher transmission efficiency, the screw-nut structure is simple and compact, the transmission is smooth, has good stability, and reduces the maintenance and replacement costs of the equipment. Therefore, the first driving mechanism 20 of the embodiment of the present application is configured as a screw-nut structure, which can improve the rotation accuracy of the piercing rod 40 and improve the piercing and suspension efficiency. It has a simple and compact structure and smooth transmission, which improves the working efficiency, stability and safety of the ton bag suspension device 100, thereby enabling the ton bags suspended by the piercing rod 40 to be transported smoothly, thereby preventing the ton bags suspended and clamped by the piercing rod 40 from shaking, ensuring the uniformity of the puncturing position of the ton bags, and improving the material unloading rate.

[0059] Of course, in some embodiments, the first drive mechanism 20 can also be configured as a pneumatic cylinder, electric cylinder, or hydraulic cylinder structure. A pneumatic cylinder refers to a cylindrical metal component that guides a piston in linear reciprocating motion within the cylinder. An electric cylinder is an electric drive device that converts the rotational motion of a motor into linear reciprocating motion of a push rod. An electric cylinder primarily consists of a motor, a reduction gear, and a linear transmission mechanism. For example, the electric cylinder serves as the prime mover for a motor reducer. A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and is primarily used to achieve reciprocating motion.

[0060] Of course, in some embodiments, the driving member 21 may include two translational drivers 211, one of which is in transmission connection with the first transmission portion 221, and the other of which is in transmission connection with the second transmission portion 222. The transmission direction of the first transmission portion 221 is opposite to the transmission direction of the second transmission portion 222, so that the first piercing rod 41 and the second piercing rod 42 rotate in opposite directions. In this way, the first piercing rod 41 and the second piercing rod 42 are driven to rotate by independent translational drivers 211, and the assembly, disassembly, maintenance, and replacement of the various parts of the ton bag hanging device 100 are facilitated.

[0061] For example, in this embodiment, the number of first piercing rods 41 corresponds to the number of second piercing rods 42, with two of each being provided. This, on the one hand, balances the forces acting on the ton bag in all directions, improving the reliability and stability of the piercing rods 40 in suspending the ton bag and extending the service life of the piercing rods 40. On the other hand, the ton bag is better propped open by the piercing rods 40, further preventing the problem of the ton bag collapsing during unloading, which affects the unloading speed and increases the amount of material remaining in the ton bag. This facilitates the unloading of the material in the ton bag and improves the unloading speed and efficiency.

[0062] The number of connecting rods 32 corresponds one-to-one with the number of hinged seats 3161 and also one-to-one with the number of puncturing rods 40. Specifically, in this embodiment, the plurality of puncturing rods 40 includes two first puncturing rods 41 and two second puncturing rods 42. The plurality of connecting rods 32 includes two first connecting rods 321 and two second connecting rods 322. The first base 311 and the second base 312 are each provided with two hinged seats 3161. The two hinged seats 3161 on the first base 311 are respectively hinged to the two first connecting rods 321, and the two hinged seats 3161 on the second base 312 are respectively hinged to the two second connecting rods 322. The two first connecting rods 321 are connected to the two first puncturing rods 41 in a one-to-one relationship, and the two second connecting rods 322 are connected to the two second puncturing rods 42 in a one-to-one relationship. Of course, in some embodiments, the number of connecting rods 32 may be less than the number of puncturing rods 40. Specifically, the connecting rod 32 includes a first connecting rod 321 and a second connecting rod 322. The number of the first puncture rod 41 and the second puncture rod 42 are both set to multiple. The multiple first puncture rods 41 can be connected to the first connecting rod 321 through a connecting rod, and the multiple first puncture rods 41 can also be connected to the second connecting rod 322 through a connecting rod.

[0063] It should be noted that the number of translational actuators 211, the number of transmission members 22, the number of connecting rod seats 31, the number of articulated seats 3161, the number of connecting rods 32, and the number of puncturing rods 40 are for illustrative purposes only and can be set according to actual circumstances. This embodiment of the present application does not specifically limit this. For example, the number of first puncturing rods 41 and the number of second puncturing rods 42 can each be set to one, three, or more.

[0064] In some embodiments, the sliding mechanism 60 includes a sliding member 61 and a guide member 62. The sliding member 61 is fixedly connected to the connecting rod seat 31. The guide member 62 is fixed to the mounting plate 10 and slidably connected to the sliding member 61. The guide member 62 extends parallel to the longitudinal direction X of the ton bag suspension device 100. Thus, the sliding arrangement of the sliding member 61 and the guide member 62 improves the smoothness and stability of the sliding mechanism 60 relative to the mounting plate 10 and absorbs and resists loads in certain directions, thereby ensuring smooth transportation of the ton bag suspended by the piercing rod 40. This prevents the ton bag suspended and clamped by the piercing rod 40 from shaking, ensures uniformity in the ton bag breaking position, and improves the material discharge rate. For example, in this embodiment, the sliding member 61 is configured as a slider and the guide member 62 is configured as a slide rail. Of course, in other embodiments, the sliding member 61 is configured as a roller and the guide member 62 is configured as a raceway.

[0065] In some embodiments, two guide slides 62 are provided, and the two ends of the connecting rod seat 31 are connected to the two guide slides 62 in a one-to-one correspondence through the two slides 61, and the transmission member 22 is located between the two slides 61. This improves the stability and reliability of the translation of the connecting rod seat 31 relative to the mounting plate 10, and through reasonable parallel arrangement in a compact space, the ton bag suspension device 100 can be tightly integrated, thereby improving space utilization.

[0066] In some embodiments, the ton bag hanging device 100 further includes a first protective cover 71. The first protective cover 71 is connected to the mounting plate 10 to form a first mounting cavity 701, and the sliding mechanism 60 and the connecting rod mechanism 30 are arranged in the first mounting cavity 701. The first protective cover 71 is at least partially configured as an elastic structure or a telescopic structure. Thus, the first protective cover 71 can seal the structural elements arranged on the top of the mounting plate 10. On the one hand, the dust generated during the ton bag breaking process cannot enter the moving hinge, thereby enhancing the movement reliability and connection stability of the first drive mechanism 20, the connecting rod mechanism 30 and the puncturing rod 40, avoiding the problem of movement wear of the moving parts of the mechanical structure due to the entry of material dust, and extending the service life; on the other hand, the metal powder and debris generated by the movement wear of the first drive mechanism 20, the connecting rod mechanism 30 and the puncturing rod 40 are blocked by the first protective cover 71 and cannot enter the material, thereby avoiding material contamination and meeting the requirements of product quality and environmental protection.

[0067] For example, in this embodiment, the translation driver 211 is positioned outside the first mounting cavity 701, thereby enabling tight integration of the ton bag suspension device 100 and improving space utilization. Specifically, the translation driver 211 is mounted on the mounting plate 10 and / or the first protective cover 71. In some embodiments, the first drive mechanism 20 further includes a sealing cover 23, which, together with the mounting plate 10, forms a sealed cavity 230 that seals the translation driver 211; alternatively, the sealing cover 23 includes a sealed cavity 230 that seals the translation driver 211. Of course, in some embodiments, the translation driver 211 can also be positioned within the first mounting cavity 701.

[0068] In this embodiment, the first protective cover 71 includes a first cover body 711 and a second cover body 712. The first cover body 711 is fixedly connected to the mounting plate 10 and is configured as a rigid structure. The second cover body 712 is connected to the end of the first cover body 711 facing away from the mounting plate 10 and is configured as an elastic or telescopic structure. Therefore, the rigidity of the first cover body 711 facilitates assembly of the first cover body 711 with the mounting plate 10 and the second cover body 712, and prevents deformation of the first cover body 711 and interference with the movement of components within the mounting cavity. The rigidity of the first cover body 711 provides support and a mounting location for other components. The first and second cover bodies 711, 712 are independently provided and fixedly connected, facilitating assembly, maintenance, and replacement of the first and second cover bodies 711, 712. The second cover body 712 is configured as an accordion cover. Furthermore, the elastic or telescopic structure of the second cover body 712 facilitates the lifting and lowering movement of the second drive mechanism 81 described below. Of course, in some embodiments, the first cover 711 and the second cover 712 can also be integrally formed. The first protective cover 71 can also be configured as an elastic structure or a telescopic structure as a whole; or the first protective cover 71 can be configured as a rigid structure as a whole, that is, the first cover 711 and the second cover 712 are both configured as elastic structures or telescopic structures.

[0069] The second cover body 712 is configured as a hollow structure with openings at both ends. Specifically, the first protective cover 71 also includes a sealing plate 713, which is sealed and connected to the side of the second cover body 712 facing away from the first cover body 711, thereby facilitating the processing and manufacturing of the first cover body 711, the second cover body 712 and the sealing plate 713, and facilitating the assembly of the first cover body 711, the second cover body 712 and the sealing plate 713. The first cover body 711, the second cover body 712 and the sealing plate 713 together form the first installation cavity 701. The sealing plate 713 and the second cover body 712 are independently arranged and fixedly connected to each other. Of course, in some embodiments, the second cover body 712 and the sealing plate 713 can be integrally formed.

[0070] For example, in this embodiment, the mounting plate 10 is connected to the first drive mechanism 20, the sliding mechanism 60, the connecting rod mechanism 30, the piercing rod 40, and the first protective cover 71 to form an integral structure 110. The ton bag hanging device 100 also includes a second drive mechanism 81 and a guide rod 82. The guide rod 82 is slidably connected to the integral structure 110 and is used to be fixedly connected to the external frame. The second drive mechanism 81 is provided on the mounting plate 10 and is used to drive the integral structure 110 to rise and fall relative to the guide rod 82 along the height direction Z of the ton bag hanging device 100. Thus, the guide rod 82 can guide the lifting and lowering of the ton bag suspended by the ton bag hanging device 100, which is formed by the connection of the mounting plate 10 with the first drive mechanism 20, the sliding mechanism 60, the connecting rod mechanism 30, the piercing rod 40, and the first protective cover 71, so that the ton bag can be lifted and lowered in a specified direction, thereby improving the stability and reliability of the lifting and lowering of the ton bag.

[0071] A guide hole 702 is provided at the position of the first protective cover 71 corresponding to the guide rod 82. The shape of the guide rod 82 is adapted to the shape of the guide hole 702. A positioning hole 101 is provided on the mounting plate 10 for the guide rod 82 to pass through. The ton bag hanging device 100 also includes a stopper 13. The guide rod 82 passes through the positioning hole 101 and is connected to the stopper 13, which is used to stop the mounting plate 10. Therefore, the provision of the stopper 13 can prevent the mounting plate 10 in the overall structure 110 from sliding off the guide rod 82, improve the reliability of the connection between the mounting plate 10 and the guide rod 82, and avoid the problem of collision with other components of the ton bag conveying device during the sliding process of the overall structure 110 relative to the guide rod 82, thereby improving the safety of the overall structure 110 during the lifting and lowering movement. The stopper 13 is provided independently of the guide rod 82 and is detachably fixed to the guide rod 82, thereby facilitating the assembly efficiency of the mounting plate 10 and the guide rod 82. Specifically, for example, the stopper 13 is configured as a nut, and a threaded section that cooperates with the nut is provided at the end of the guide rod 82 near the mounting plate 10. Of course, in some embodiments, the stopper 13 can also be integrally formed with the guide rod 82, thereby improving the reliability and stability of the connection between the stopper 13 and the guide rod 82.

[0072] Please also refer to Figures 5 to 7 , Figure 6 yes Figure 1 A structural schematic diagram of the ton bag hanging device 100 from a second perspective; Figure 7 yes Figure 6An enlarged view of part I of the ton bag hanging device 100 in FIG. In some embodiments, the ton bag hanging device 100 further includes a stopper 14. The stopper 14 is disposed at one end of the guide rod 82 near the mounting plate 10 and is used to confine the stopper 13 between the mounting plate 10 and the stopper 14. Thus, the provision of the stopper 14 can prevent the stopper 13 from slipping off the guide rod 82, thereby improving the reliability of the connection between the stopper 13 and the guide rod 82. Specifically, the guide rod 82 is provided with a through hole 820, and the stopper 14 is passed through the through hole 820 and can be used to stop the stopper 13. The stopper 14 can be configured as a hairpin structure, thereby facilitating the assembly of the stopper 14 with the guide rod 82 and improving the reliability and stability of the connection between the stopper 14 and the guide rod 82. Specifically, the stopper 14 is formed by bending an elastic wire. The stopper 14 includes two clamping arms 141 and a connecting wall connecting the two clamping arms 141. The connecting wall is used to stop the through hole 820, thereby limiting the depth of the limiter 14 inserted into the through hole 820. Of course, in some embodiments, the limiter 14 can also be configured as a rigid structure, such as a bolt, pin or screw, etc., which is not specifically limited in the embodiment of the present application.

[0073] Please refer again Figure 1 and Figure 5The connection between the second drive mechanism 81 and the mounting plate 10 forms a first hinge portion 83. The hinged connection between the puncture rod 40 or the swinging rod 50 and the connecting rod mechanism 30 forms a second hinge portion 33. Both the first hinge portion 83 and the second hinge portion 33 are disposed within the first mounting cavity 701. Thus, based on the hinged connection between the second drive mechanism 81 and the mounting plate 10, on the one hand, the first hinge portion 83 can absorb and disperse the applied force, reducing mechanical damage to the second drive mechanism 81 caused by external forces, thereby extending the service life of the device; on the other hand, the hinged connection between the second drive mechanism 81 and the mounting plate 10 allows the second drive mechanism 81 to move and rotate in multiple directions, providing greater flexibility and adaptability. Of course, in some embodiments, the second drive mechanism 81 and the mounting plate 10 can also be fixedly connected, thereby improving the stability of the connection between the second drive mechanism 81 and the mounting plate 10, and the structure is simple; on the one hand, based on the fact that the first hinge part 83 and the second hinge part 33 are both arranged in the first mounting cavity 701, the dust generated during the bag breaking process of the ton bag cannot enter the first hinge part 83 and the second hinge part 33, thereby enhancing the movement reliability and connection stability of the second drive mechanism 81 and the mounting plate 10 and the connecting rod mechanism 30 and the puncture rod 40 or the swing rod 50, avoiding the problem of movement wear of the moving parts of the mechanical structure due to the entry of material dust, and extending the service life of the second drive mechanism 81 and the mounting plate 10 and the connecting rod mechanism 30 and the puncture rod 40 or the swing rod 50; on the other hand, the metal powder and debris generated by the movement wear of the second drive mechanism 81 and the mounting plate 10 and the connecting rod mechanism 30 and the puncture rod 40 or the swing rod 50 are blocked by the first protective cover 71 and cannot enter the material, thereby avoiding material contamination and meeting the requirements of product quality and environmental protection. For example, in this embodiment, the connecting rod mechanism 30 and the puncture rod 40 are indirectly hinged via the swinging rod 50. Specifically, the connecting rod mechanism 30 and the swinging rod 50 are hinged to form the second hinge portion 33. Of course, in some embodiments, the connecting rod mechanism 30 and the puncture rod 40 can be directly hinged to form the second hinge portion 33.

[0074] Specifically, the first drive mechanism 20 is used to drive the connecting rod mechanism 30 and the sliding mechanism 60 to move synchronously along the length direction X of the ton bag suspension device 100, thereby achieving rotation of the puncturing rod 40. A support frame 15 is provided on the mounting plate 10. The second drive mechanism 81 includes a lifting drive 811 and a lifting rod 812. One end of the lifting rod 812 is transmission-connected to the lifting drive 811, and the other end of the lifting rod 812 is hinged to the mounting plate 10 via the support frame 15. The lifting drive 811 is used to drive the lifting rod 812 to drive the overall structure 110 to rise and fall relative to the guide rod 82 along the height direction Z of the ton bag suspension device 100. The support frame 15 is used to stop the sliding mechanism 60. Therefore, on the one hand, the second drive mechanism 81 is supported by the support frame 15, thereby avoiding interference between the translational movement of the first drive mechanism 20 and the lifting movement of the second drive mechanism 81. The structural layout is reasonable and compact, which can achieve tight integration of the ton bag hanging device 100 and improve space utilization; on the other hand, based on the setting of the support frame 15 and the stopper of the sliding mechanism 60, the problem of the puncturing rod 40 being punctured in the hanging state due to excessive rotation angle is avoided, thereby improving the safety of the use of the ton bag hanging device 100.

[0075] Specifically, along the length direction X of the ton bag hanging device 100, the support frame 15 is located between the first base 311 and the second base 312. As a result, the second drive mechanism 81 is located approximately at the center of the overall structure, so that the second drive mechanism 81 can bear external forces more evenly, improving the durability and safety of the structure, and optimizing the performance of the structure formed by the second drive mechanism 81 and the overall structure 110, thereby improving the connection stability and reducing vibration. A clearance space 103 is formed between the support frame 15 and the mounting plate 10 to avoid the screw rod 212, thereby ensuring the reliability of the first drive mechanism 20 driving the puncture rod 40 to rotate. The lifting rod 812 is hingedly connected to the support frame 15 to form a first hinge portion 83. The second drive mechanism 81 can be configured as, but not limited to, a cylinder structure, an electric cylinder structure, or a hydraulic cylinder structure. For example, in this embodiment, the second drive mechanism 81 is described as a cylinder structure. The lifting rod 812 is configured as a telescopic rod. The lifting working principle of the cylinder structure is mainly to drive the transmission of the chain through the telescopic movement of the cylinder, and then drive the rotation of the sprocket to achieve the lifting and lowering of the entire structure 110.

[0076] The ton bag hanging device 100 also includes a tension and compression weighing sensor 90. The support frame 15 includes a first frame body 151 and a second frame body 152. The first frame body 151 is connected to the mounting plate 10, and the second frame body 152 is connected to the lifting rod 812 and is connected to the first frame body 151 through a tension and compression weighing sensor 90. The tension and compression weighing sensor 90 is used to weigh the weight of the overall structure 110 and the ton bag. Therefore, based on the setting of the tension and compression weighing sensor 90, the user can quickly and accurately know the residual amount of material in the ton bag. It can be understood that when the value detected by the tension and compression weighing sensor 90 is continuously less than the set threshold, it indicates that the material in the ton bag is completely unloaded. When the value detected by the tension and compression weighing sensor 90 is continuously greater than the set threshold, it indicates that the material in the ton bag is not completely unloaded. The threshold value can be set according to the weight of the unloaded material in the ton bag, and the embodiment of the present application does not make specific limitations.

[0077] In some embodiments, the ton bag suspension device 100 further includes a second protective cover 72. The second protective cover 72 is connected to the mounting plate 10 to form a second mounting cavity 703. The hinged connection between the piercing rod 40 or the swinging rod 50 and the mounting plate 10 forms a third hinge portion 43. The third hinge portion 43 is disposed within the second mounting cavity 703. The second protective cover 72 is provided with a relief hole 704 that cooperates with the piercing rod 40. The end of the piercing rod 40 facing away from the linkage mechanism 30 extends out of the relief hole 704. The second protective cover 72 is at least partially configured as an elastic structure or a telescopic structure. Therefore, based on the arrangement of the second protective cover 72 with the avoidance hole 704 that matches the puncture rod 40, the dust generated during the bag breaking process of the ton bag is prevented from entering the second mounting cavity 703, thereby enhancing the movement reliability and connection stability of the mounting plate 10 or the swing rod 50 and the puncture rod 40, avoiding the movement wear problem of the moving parts of the mechanical structure due to the entry of material dust, and extending the service life of the mounting plate 10 or the swing rod 50 and the puncture rod 40; on the other hand, the metal powder generated due to movement wear between the mounting plate 10 or the swing rod 50 and the puncture rod 40 is prevented from entering the second mounting cavity 703. Powder and debris are blocked by the second protective cover 72 and cannot enter the material, thus avoiding material contamination and meeting the requirements of product quality and environmental protection; on the other hand, when the piercing rod 40 is in the process of piercing or hanging the ton bag, the second protective cover 72 may come into contact with the ton bag, or even squeeze the second protective cover 72. Therefore, in the embodiment of the present application, the second protective cover 72 is at least partially configured as an elastic structure or a telescopic structure, so that the second protective cover 72 can at least partially deform to improve the sealing between the second protective cover 72 and the piercing rod 40, and adapt to the rotation function of the piercing rod 40.

[0078] In this embodiment, the second protective cover 72 is partially configured as an elastic structure or a telescopic structure. Specifically, the second protective cover 72 includes a cover shell 721 and a cover 722. The cover shell 721 is mounted on the mounting plate 10. Specifically, a flange seat 723 is provided at one end of the cover shell 721 facing the mounting plate 10, thereby facilitating the assembly of the second protective cover 72 and the mounting plate 10. The cover 722 is installed in the cover shell 721 and, together with the cover shell 721 and the mounting plate 10, forms a second mounting cavity 703. The cover shell 721 is configured as a rigid structure, and the cover 722 is configured as an elastic structure or a telescopic structure, and is provided with a avoidance hole 704 that cooperates with the piercing rod 40. Therefore, the rigidity of the cover shell 721 can prevent the cover 722 from being damaged by being squeezed by the ton bag, thereby extending the service life of the second protective cover 72 and improving the sealing performance of the second mounting cavity 703, preventing material from entering the second mounting cavity 703 and preventing debris from contaminating the material. Of course, in some embodiments, the second protective cover 72 can be configured as an elastic structure or a telescopic structure. In other embodiments, the second protective cover 72 can also be configured as a rigid structure, with an elastic seal disposed between the cover 722 and the puncture rod 40 to achieve a sealing function and enable the puncture rod 40 to rotate.

[0079] In this embodiment, the bottom of the housing 721 extends relative to the cover 722, toward the side facing away from the mounting plate 10. Specifically, a protective space 705 is formed between the end of the housing 721 facing away from the mounting plate 10 and the cover 722. As a result, when the piercing rod 40 pierces or suspends a large-volume bag, the housing 721 first contacts the bag, preventing damage to the cover 722 caused by the bag's pressure. This improves the sealing connection between the cover 722, the housing 721, and the piercing rod 40, and extends the service life of the second protective cover 72.

[0080] The mounting plate 10 is provided with a movable hole 102 that communicates with the second mounting cavity 703. The piercing rod 40 is movable within the movable hole 102, and the second protective cover 72 covers the movable hole 102. Thus, on the one hand, the piercing rod 40 is movable within the movable hole 102, thereby enabling the piercing rod 40 to rotate a preset angle to switch between the piercing state and the hanging state, thereby improving the reliability and smoothness of the piercing rod 40's rotation. On the other hand, the provision of the second protective cover 72 covering the movable hole 102 prevents dust generated during the bag breaking process from entering the second mounting cavity 703, thereby enhancing the movement reliability and connection stability of the piercing rod 40 and the connecting rod mechanism 30, preventing wear and tear of the moving parts of the mechanical structure due to the ingress of material dust, and extending the service life of the piercing rod 40 and the connecting rod mechanism 30. Furthermore, metal powder and debris generated by wear and tear of the piercing rod 40 and the connecting rod mechanism 30 are blocked by the second protective cover 72 and cannot enter the material, thereby preventing material contamination and meeting product quality and environmental protection requirements.

[0081] In some embodiments, the movable hole 102 is strip-shaped, and the width of the movable hole 102 along the width direction Y of the ton bag hanging device 100 is approximately equal to the radial dimension of the puncture rod 40, so that the movable hole 102 can guide the rotation of the puncture rod 40. Of course, in other embodiments, the width of the movable hole 102 along the width direction Y of the ton bag hanging device 100 can also be greater than the radial dimension of the puncture rod 40.

[0082] In this embodiment, the sidewall of the second protective cover 72 is further provided with a limiting groove 706. The limiting groove 706 can be provided in one or more ways. In this embodiment, two limiting grooves 706 are provided, one of which is provided close to the puncture rod 40, and the other limiting groove 706 is provided away from the puncture rod 40, thereby facilitating the processing and manufacturing of the second protective cover 72. Of course, it should be noted that the number and location of the limiting grooves 706 can be set according to the swinging trajectory of the puncture rod 40 driven by the connecting rod mechanism 30, and are not specifically limited in this embodiment of the application. For example, in some embodiments, the sidewall of the second protective cover 72 can be provided with only one limiting groove 706 away from the puncture rod 40.

[0083] When the first angle α is greater than or equal to the second preset value, the puncturing rod 40 is inserted into the limiting groove 706. The limiting groove 706 is used to limit the maximum rotation angle of the puncturing rod 40. Specifically, the limiting groove 706 is provided at the end of the cover 721 away from the mounting plate 10. The limiting groove 706 penetrates the end surface of the cover 721 away from the mounting plate 10, so that the puncturing rod 40 can be extended into the limiting groove 706. Therefore, when the puncturing rod 40 is rotated to the maximum rotation angle, the puncturing rod 40 and the bottom wall of the limiting groove 706 are limited and stopped, thereby avoiding the problem of the ton bag being punctured in the suspended state due to the excessive rotation angle of the puncturing rod 40, thereby improving the safety of the ton bag suspension device 100.

[0084] Please also refer to Figures 1 to 3When the ton bag hanging device 100 is in use, the first drive mechanism 20 drives the connecting rod mechanism 30 to rotate the piercing rod 40 in a first direction such that the first angle α is less than or equal to a first preset value. For example, the first drive mechanism 20 drives the connecting rod mechanism 30 to rotate the piercing rod 40 until the extension direction of the piercing rod 40 is substantially perpendicular to the piercing surface of the ton bag. The second drive mechanism 81 drives the piercing rod 40 toward the ton bag until the ton bag is pierced. After the ton bag is pierced, the first drive mechanism 20 again drives the connecting rod mechanism 30 to rotate the piercing rod 40 in a second direction such that the first angle α is greater than or equal to a second preset value. For example, the first driving mechanism 20 drives the connecting rod mechanism 30 to drive the puncturing rod 40 to rotate to a position where the extension direction of the puncturing rod 40 is approximately perpendicular to the puncturing surface of the ton bag. At this time, the first puncturing rod 41 and the second puncturing rod 42 support the ton bag to avoid the problem that the ton bag is easily affected by the collapse of the bag body during the unloading process, affecting the dropping speed and increasing the residual amount of material in the ton bag, facilitating the falling of the material in the ton bag, and improving the unloading rate and unloading effect.
