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

[0037] Please also read Figures 1 to 3 , Figure 1 It is a structural schematic diagram of the ton bag hanging device 100 provided in an embodiment of the present application with the sealing plate 713 omitted from the first perspective; Figure 2 yes Figure 1 A cross-sectional view of the ton bag suspension device 100 in a punctured state, Figure 3 yes Figure 1A cross-sectional view of a ton bag hanging device 100 in a hanging state. The embodiment of the present application provides a ton bag hanging device 100. The ton bag hanging device 100 includes a mounting plate 10, a first driving mechanism 20, a connecting rod mechanism 30 and a plurality of piercing rods 40. The first driving mechanism 20 is arranged on the mounting plate 10. The connecting rod mechanism 30 is transmission-connected to the first driving mechanism 20. The plurality of piercing rods 40 are respectively hinged to the connecting rod mechanism 30; the first driving mechanism 20 is used to drive the connecting rod mechanism 30 to drive the plurality of piercing rods 40 to rotate. Among them, the angle formed by the extension direction of the piercing rod 40 and the height direction Z of the ton bag hanging device 100 is the first angle α. When the first angle α is less than or equal to the first preset value, the plurality of piercing rods 40 are used to pierce the ton bag and detach from the ton bag. When the first angle α is greater than or equal to the second preset value, the plurality of piercing rods 40 are used to hang the ton bag, and the plurality of piercing rods 40 are inclined toward the four sides of the ton bag relative to the height direction Z of the ton bag hanging device 100.

[0038] The ton bag hanging device 100 provided in the embodiment of the present application is based on the setting of the 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 from the ton bag. 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 the 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 driving mechanism 20, the connecting rod mechanism 30 and the plurality of puncturing rods 40, and it is not to specifically limit the connection position, connection relationship and specific structure of each component. 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, strong load-bearing freight packaging bag used for packaging and transportation, and is usually used for the transportation of solid goods, such as granular materials, powdered materials, and block materials. Ton bags are used to load materials, such as but not limited to battery materials, food materials, pharmaceutical materials, fertilizer materials, building materials, etc., and the materials loaded in the ton bag are not limited here. For example, in an embodiment of the present application, the ton bag is used to load battery materials. Battery materials are, for example, but not limited to positive electrode materials, negative electrode materials, conductive agents or dispersants, etc.; or, various materials are mixed to form battery mixed materials.

[0041] For the accuracy of description, please refer to the directions 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 lift and lower, that is, the up-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 of the drawings, and this application does not make specific restrictions. For the convenience of description, the upper, lower, left, right, front, and rear directions in this application are relative positions and do not constitute restrictions 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 the embodiment of the present application does not make specific limitations. 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 puncturing rod 40 and the height direction Z of the ton bag suspension device 100 in the puncturing state, so that the puncturing rod 40 is easier to puncture the ton bag. When the value of the second preset value is larger, the angle between the extension direction of the puncturing 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 puncturing rod 40, and improving the reliability and stability of the puncturing rod 40 hanging the ton bag.

[0043] The first angle α is 0°-90°. Thus, on the one hand, the rotation angle range of the piercing rod 40 is increased, so that the ton bag hanging device 100 can be freely switched between the piercing state and the hanging state, and the piercing rod 40 has both the piercing and hanging functions, thereby realizing the diversified use functions of the ton bag hanging device 100, and the structure is simple and compact; on the other hand, by limiting the rotation angle of the piercing rod 40, the piercing 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 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°, it indicates that the extension direction of the puncture rod 40 is parallel to the height direction Z of the ton bag hanging device 100, and the puncture rod 40 is substantially perpendicular to the puncture surface of the ton bag, thereby improving the puncture effect of the puncture rod 40, and making the size of the puncture hole of the ton bag smaller, avoiding the problem of tearing at the puncture hole due to the large size of the puncture hole, thereby improving the reliability and stability of the subsequent hanging of the ton bag by the puncture rod 40. When the first angle α is 90° or close to 90°, it indicates that the extension direction of the puncture rod 40 is perpendicular to the height direction Z of the ton bag hanging device 100, and the puncture rod 40 is substantially parallel to the puncture surface of the ton bag, thereby improving the hanging effect of the puncture rod 40 on the ton bag. It can be understood that when the first angle α is greater than 90°, the puncture tip of the puncture rod 40 is easy to puncture the ton bag again, thereby easily causing the ton bag to tear and slide off the puncture 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 read Figure 1 and Figure 4 , Figure 4 yes Figure 1A structural diagram of a partial structure of a 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 making the piercing rod 40 flexible in rotating in a specified direction; on the other hand, based on setting the extension direction of the swing rod 50 to be an obtuse angle with 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 caused by 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 rod 50 is hinged to the connecting rod mechanism 30, and the other end of the swing rod 50 is hinged to the mounting plate 10. Specifically, a pivot seat 11 is provided on the mounting plate 10, and the swing rod 50 is pivoted to the pivot seat 11 through a pivot shaft 12, so that the first driving mechanism 20 drives the connecting rod mechanism 30 to drive the swing rod 50 to rotate together with the piercing rod 40. In some embodiments, a reinforcing structure 51 is provided at the position of the swing rod 50 corresponding to the pivot seat 11, and the reinforcing structure 51 is pivoted to the pivot seat 11 through the pivot shaft 12. Therefore, the reinforcing structure 51 can enhance the structural strength of the swing rod 50, avoid the problem of the swing rod 50 breaking, and improve the safety of the ton bag suspension device 100.

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

[0047] In some embodiments, the swing rod 50 is connected to the puncture rod 40 in a smooth transition. Thus, on the one hand, the stress concentration between the swing rod 50 and the puncture rod 40 is reduced, and the service life of the puncture rod 40 is extended; on the other hand, the connection strength and stability between the swing rod 50 and the puncture rod 40 are improved.

[0048] Please also read 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 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, improve the stability and accuracy of the movement of the connecting rod mechanism 30, and prevent the ton bag suspended by the piercing rod 40 from shaking, ensure the uniformity of the ton bag breaking position, and improve the material unloading rate; on the other hand, the setting of the sliding mechanism 60 can also reduce the friction force 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. Exemplarily, 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 length 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, and the embodiments of the present application do not make specific limitations.

[0049] Please refer again Figure 2 and Figure 5 , the connecting rod mechanism 30 includes a connecting rod seat 31 and a plurality of connecting rods 32. 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 3, exemplarily, in the present 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 the 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 the fourth angle δ. Exemplarily, in the present 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 connecting rod 32 and the piercing rod 40 are subjected to uniform force, 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 puncturing rod 40 means that the central axis of the connecting rod 32 is parallel to the central axis of the puncturing rod 40 connected to the connecting rod 32 .

[0051] It should be noted that the term "parallel" means that when there is no common point between two straight lines on a plane, two planes in space, and a straight line and a plane in space, they are called parallel. The term "perpendicular" means that when a line on a plane intersects with another line at right angles, the two lines are perpendicular to each other. In the embodiments of the present application, descriptions such as parallel and perpendicular can include situations where approximately parallel and approximately perpendicular are caused by processing errors, measurement errors, etc.

[0052] In this embodiment, the connecting rod seat 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 suspension 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. Therefore, on the one hand, based on 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 suspension device 100, the available space can be utilized to the maximum extent to avoid 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 seat 31, so that the integrated structure formed by connecting the connecting rod seat 31 with the transmission member 22, the connecting rod mechanism 30 and the sliding mechanism 60 is more solid and reliable, and in a compact space, through reasonable arrangement, the ton bag suspension device 100 can be tightly integrated and the space utilization rate can be improved. Specifically, an articulated seat 3161 is provided at a position of the connecting rod seat 31 corresponding to the second connecting portion 316, and the connecting rod mechanism 30 is articulated with the articulated seat 3161 through the articulated shaft 3162, so that the first driving mechanism 20 drives the connecting rod 32 to rotate to a preset angle relative to the connecting rod seat 31. In some embodiments, a reinforcing structure 51 is also provided at a position of the connecting rod 32 corresponding to the articulated seat 3161, and the reinforcing structure 51 is articulated with the articulated seat 3161 through the articulated shaft 3162. Thus, the reinforcing structure 51 can enhance the structural strength of the connecting rod 32, avoid the problem of the connecting rod 32 being broken, and improve the safety of the ton bag suspension device 100.

[0053] Please refer again Figure 2 and Figure 5, exemplarily, in the present embodiment, the plurality of piercing rods 40 include a first piercing rod 41 and a second piercing 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 piercing 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 piercing 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 with the first transmission part 221, the first connecting rod 321 and the first piercing rod 41 to form a first transmission module 510, and the second base 312 is connected with the second transmission part 222, the second connecting rod 322 and the second piercing 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 to move in opposite directions, so that the first piercing rod 41 and the second piercing rod 42 rotate in opposite directions. The first transmission module 510 and the second transmission module 520 are each provided in plurality, and each first transmission module 510 and the corresponding second transmission module 520 are arranged at intervals along a preset direction. 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 open the ton bag, thereby avoiding the problem that the ton bag is easily affected by the deflation 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 uniformity of the force 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 the preset direction refers to a direction defined artificially, for example, the preset direction is any direction in the plane where the mounting plate 10 is located. 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, the width direction Y of the ton bag hanging device 100, or other directions in the plane where the mounting plate 10 is located.

[0055] The preset direction includes a first direction and a second direction, the first direction intersects with the second direction, and each of the first transmission modules 510 and the corresponding second transmission modules 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 suspension device 100, and the second direction is the width direction Y of the ton bag suspension 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 arranged at intervals along the length direction X or the width direction Y of the ton bag suspension device 100, that is, all first transmission modules 510 and corresponding second transmission modules 520 are arranged at intervals along the length direction X or the width direction Y of the ton bag suspension device 100. At this time, the ton bag suspension device 100 can be provided with only one sliding mechanism 60, which improves the compactness of the overall structure of the ton bag suspension device 100, has 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 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. Thus, the assembly of the first transmission modules 510 and the second transmission modules 520 is facilitated, and in a compact space, through reasonable parallel arrangement, the ton bag suspension device 100 can be tightly integrated to improve the utilization of space.

[0056] Of course, in some embodiments, part of the first transmission module 510 and the corresponding second transmission module 520 are arranged at intervals along the first direction, and the rest of the first transmission module 510 and the corresponding second transmission module 520 are arranged at intervals along the second direction. For example, part of the first transmission module 510 and part of the second transmission module 520 are arranged at intervals along the length direction X of the ton bag suspension device 100; the rest of the first transmission module 510 and part of the second transmission module 520 are arranged at intervals along the width direction Y of the ton bag suspension device 100. At this time, the ton bag suspension device 100 needs to be provided with two sliding mechanisms 60, wherein the sliding direction of one sliding mechanism 60 is parallel to the length direction X of the ton bag suspension device 100, wherein the sliding direction of the other sliding mechanism 60 is parallel to the width direction Y of the ton bag suspension device 100, so as to realize that the first transmission module 510 and part of the second transmission module 520 in different directions 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 further 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, which facilitates the falling of the material in the ton bag and improves the unloading rate and unloading effect.

[0057] The driving member 21 includes a translation driver 211 and a screw rod 212 drivingly connected to the translation driver 211. The first transmission part 221 is provided with a first screw hole 2211 screwed to the screw rod 212, and the second transmission part 222 is provided with a second screw hole 2221 screwed 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, the first transmission part 221 and the second transmission part 222 are driven to move in different directions by a translation driver 211, 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 of the thread direction of the first screw hole 2211 to be 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. The structure is simple and compact, and the transmission is smooth, which improves the working efficiency, stability and safety of use of the ton bag hanging 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 ton bag breaking position, and improving the material unloading rate.

[0059] Of course, in some embodiments, the first drive mechanism 20 can also be configured as a cylinder structure, an electric cylinder structure or a hydraulic cylinder structure. The cylinder structure refers to a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The electric cylinder structure is an electric drive device that converts the rotary motion of the motor into the linear reciprocating motion of the push rod. The electric cylinder structure is mainly composed of a motor, a reduction device and a linear transmission mechanism. For example, the electric cylinder structure is a motor reducer prime mover. The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, and is mainly used to achieve reciprocating motion.

[0060] Of course, in some embodiments, the driving member 21 may include two translation drivers 211, one of which is in driving connection with the first transmission part 221, and the other of which is in driving connection with the second transmission part 222, and the transmission direction of the first transmission part 221 is opposite to the transmission direction of the second transmission part 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 the translation drivers 211 independently arranged from each other, and the assembly, disassembly, maintenance and replacement of the various parts of the ton bag suspension device 100 are facilitated.

[0061] For example, in this embodiment, the number of the first piercing rods 41 corresponds to the number of the second piercing rods 42, and each is set to two. Therefore, on the one hand, the force on the ton bag in all directions is balanced, the reliability and stability of the piercing rod 40 hanging the ton bag are improved, and the service life of the piercing rod 40 is extended; on the other hand, the ton bag is better opened by the piercing rod 40, further 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 the material in the ton bag, which facilitates the falling of the material in the ton bag and improves the unloading rate and unloading effect.

[0062] The number of connecting rods 32 corresponds to the number of hinged seats 3161, and also corresponds to the number of puncture rods 40. Specifically, in the present embodiment, the plurality of puncture rods 40 include two first puncture rods 41 and two second puncture rods 42. The plurality of connecting rods 32 include two first connecting rods 321 and two second connecting rods 322. Two hinged seats 3161 are respectively provided on the first base 311 and the second base 312, and 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 puncture rods 41 in a one-to-one correspondence, and the two second connecting rods 322 are connected to the two second puncture rods 42 in a one-to-one correspondence. Of course, in some embodiments, the number of connecting rods 32 may be less than the number of puncture rods 40. Specifically, the connecting rod 32 includes a first connecting rod 321 and a second connecting rod 322, and the number of the first puncture rod 41 and the second puncture rod 42 are both set to multiple. Multiple first puncture rods 41 can be connected to the first connecting rod 321 through a connecting rod, and 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 translation drivers 211, the number of transmission members 22, the number of connecting rod seats 31, the number of hinge seats 3161, the number of connecting rods 32, and the number of puncture rods 40 are only for illustration and can be set according to actual conditions, and are not specifically limited in the embodiments of the present application. For example, the number of first puncture rods 41 and the number of second puncture rods 42 can also be set to one, three, or more than three.

[0064] In some embodiments, the sliding mechanism 60 includes a sliding member 61 and a guide sliding member 62. The sliding member 61 is fixedly connected to the connecting rod seat 31. The guide sliding member 62 is fixed to the mounting plate 10 and is slidably connected to the sliding member 61. The extension direction of the guide sliding member 62 is parallel to the length direction X of the ton bag hanging device 100. Thus, the sliding arrangement of the sliding member 61 and the guide sliding member 62 can improve the smoothness and stability of the sliding mechanism 60 relative to the mounting plate 10 and absorb and resist the load in some directions, so that the ton bag suspended by the piercing rod 40 can be transported smoothly, thereby preventing the ton bag suspended and clamped by the piercing rod 40 from shaking, ensuring the uniformity of the ton bag breaking position, and improving the material unloading rate. Exemplarily, in this embodiment, the sliding member 61 is configured as a slider, and the guide sliding member 62 is configured as a slide rail. Of course, in some other embodiments, the sliding member 61 is configured as a roller, and the guide sliding 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. Thus, the stability and reliability of the translation of the connecting rod seat 31 relative to the mounting plate 10 are improved, and in a compact space, through reasonable parallel arrangement, the ton bag suspension device 100 can be tightly integrated and the space utilization rate can be improved.

[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 driving mechanism 20, the connecting rod mechanism 30 and the piercing 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 driving mechanism 20, the connecting rod mechanism 30 and the piercing rod 40 are blocked by the first protective cover 71 and cannot enter the material, thereby avoiding material pollution and meeting the requirements of product quality and environmental protection.

[0067] Exemplarily, in this embodiment, the translation driver 211 is arranged outside the first installation cavity 701, so that the ton bag suspension device 100 can be tightly integrated and the space utilization rate can be improved. Specifically, the translation driver 211 is installed on the mounting plate 10 and / or the first protective cover 71. In some embodiments, the first driving mechanism 20 further includes a sealing cover 23, and the sealing cover 23 and the mounting plate 10 enclose a sealing cavity 230 for sealing the translation driver 211; or, a sealing cavity 230 for sealing the translation driver 211 is arranged in the sealing cover 23. Of course, in some embodiments, the translation driver 211 can also be arranged in the first installation 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 configured as a rigid structure. The second cover body 712 is connected to one end of the first cover body 711 facing away from the mounting plate 10 and configured as an elastic structure or a telescopic structure. Therefore, on the one hand, based on the configuration of the first cover body 711 as a rigid structure, it is convenient to assemble the first cover body 711 with the mounting plate 10 and the second cover body 712, and avoid the problem that the first cover body 711 is deformed and interferes with the movement of the parts in the mounting cavity. The rigidity of the first cover body 711 can provide support and installation sites for other parts. The first cover body 711 and the second cover body 712 are independently arranged and fixedly connected, so that the first cover body 711 and the second cover body 712 can be assembled, maintained, replaced, etc. The second cover body 712 is configured as an accordion cover; on the other hand, based on the configuration of the second cover body 712 as an elastic structure or a telescopic structure, the lifting movement of the second driving mechanism 81 described below is realized. Of course, in some embodiments, the first cover body 711 and the second cover body 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 body 711 and the second cover body 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, so as to facilitate the processing and manufacturing of the first cover body 711, the second cover body 712 and the sealing plate 713, and facilitate 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 are surrounded to form the first installation cavity 701. The sealing plate 713 and the second cover body 712 are independently arranged and fixedly connected. Of course, in some embodiments, the second cover body 712 and the sealing plate 713 can be integrally formed.

[0070] Exemplarily, in this embodiment, the mounting plate 10 is connected with the first driving 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 driving mechanism 81 and a guide rod 82. The guide rod 82 is slidably connected with the integral structure 110 and is used to be fixedly connected with the external frame. The second driving mechanism 81 is arranged on the mounting plate 10 and is used to drive the integral structure 110 to be lifted and lowered 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 and the integral structure 110 formed by connecting the mounting plate 10 with the first driving 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, and 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, and the stopper 13 is used to stop the mounting plate 10. Therefore, the setting 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 parts of the ton bag conveying device during the sliding rod of the overall structure 110 relative to the guide rod 82, thereby improving the safety of the overall structure 110 in the lifting and lowering movement. The stopper 13 and the guide rod 82 are independently provided, and are detachably fixedly connected to the guide rod 82, thereby facilitating the assembly efficiency of the mounting plate 10 and the guide rod 82. Specifically, illustratively, the stopper 13 is configured as a nut, and a threaded section that cooperates with the nut and is fixed is provided at the end of the guide rod 82 close to 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 read Figures 5 to 7 , Figure 6 yes Figure 1 A schematic structural diagram of the ton bag hanging device 100 from a second perspective; Figure 7 yes Figure 61 is an enlarged view of part I of the ton bag hanging device 100. In some embodiments, the ton bag hanging device 100 also includes a stopper 14. The stopper 14 is arranged at one end of the guide rod 82 close to the mounting plate 10, and is used to limit the stopper 13 between the mounting plate 10 and the stopper 14. Therefore, the setting of the stopper 14 can avoid the problem of the stopper 13 slipping off the guide rod 82, and improve 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 penetrated in the through hole 820 and can be used to stop the stopper 13. The stopper 14 can be configured as a hairpin structure, so as to facilitate the assembly of the stopper 14 and the guide rod 82, and improve the reliability and stability of the connection between the stopper 14 and the guide rod 82. Specifically, the stopper 14 is a structure formed by bending an elastic wire. The stopper 14 includes two clamp arms 141 and a connecting wall connecting the two clamp 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, a pin or a screw, etc., which is not specifically limited in the embodiment of the present application.

[0073] Please refer again Figure 1 and Figure 5, the connection between the second driving mechanism 81 and the mounting plate 10 forms a first hinged portion 83. The hinged portion between the piercing rod 40 or the swinging rod 50 and the connecting rod mechanism 30 forms a second hinged portion 33, and both the first hinged portion 83 and the second hinged portion 33 are arranged in the first mounting cavity 701. Therefore, based on the hinged connection between the second driving mechanism 81 and the mounting plate 10, on the one hand, the first hinged portion 83 can absorb and disperse the force, reduce the mechanical damage of the second driving mechanism 81 caused by the external force, thereby extending the service life of the device; on the other hand, the hinged connection between the second driving mechanism 81 and the mounting plate 10 can allow the second driving 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 83 and the second hinge 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 83 and the second hinge 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 piercing rod 40 or the swing rod 50, 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 second drive mechanism 81 and the mounting plate 10 and the connecting rod mechanism 30 and the piercing 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 piercing rod 40 or the swing rod 50 are blocked by the first protective cover 71 and cannot enter the material, thereby avoiding material pollution and meeting the requirements of product quality and environmental protection. Exemplarily, in this embodiment, the link mechanism 30 and the puncture rod 40 are indirectly hinged through the swing rod 50. Specifically, the link mechanism 30 and the swing rod 50 are hinged to form the second hinge portion 33. Of course, in some embodiments, the link mechanism 30 and the puncture rod 40 can be directly hinged to form the second hinge portion 33.

[0074] Specifically, the first driving 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 hanging device 100, so as to realize the rotation of the piercing rod 40. A support frame 15 is provided on the mounting plate 10, and the second driving mechanism 81 includes a lifting driver 811 and a lifting rod 812. One end of the lifting rod 812 is connected to the lifting driver 811 by transmission, and the other end of the lifting rod 812 is hinged to the mounting plate 10 through the support frame 15. The lifting driver 811 is used to drive the lifting rod 812 to drive the overall structure 110 to lift and lower along the height direction Z of the ton bag hanging device 100 relative to the guide rod 82. 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, so as to avoid 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 realize the tight integration of the ton bag hanging device 100 and improve the utilization rate of space; 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 piercing rod 40 rotating too much and causing the ton bag to be punctured in the hanging state 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 suspension 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 approximately located at the center of the overall mechanism, so that the second drive mechanism 81 can bear the external force more evenly, improve the durability and safety of the structure, and optimize the performance of the structure formed by the connection between the second drive mechanism 81 and the overall structure 110, thereby improving the connection stability and reducing vibration. A space 103 for avoiding the screw rod 212 is formed between the support frame 15 and the mounting plate 10, thereby achieving the reliability of the first drive mechanism 20 driving the piercing rod 40 to rotate. The lifting rod 812 is hingedly connected to the support frame 15 to form a first hinged 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. By way of example, in this embodiment, the second drive mechanism 81 is described by taking the second drive mechanism 81 as a cylinder structure as an example. 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 overall 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 151 and a second frame 152. The first frame 151 is connected to the mounting plate 10, and the second frame is connected to the lifting rod 812, and is connected to the first frame 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, and 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 hanging 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. A third hinge portion 43 is formed at a hinge between the piercing rod 40 or the swing rod 50 and the mounting plate 10. The third hinge portion 43 is disposed in the second mounting cavity 703. The second protective cover 72 is provided with an avoidance hole 704 that matches the piercing rod 40. One end of the piercing rod 40 that faces away from the connecting rod mechanism 30 extends out of the avoidance 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 matching the piercing rod 40, the dust generated during the bag breaking process of the ton bag is prevented from entering the second mounting cavity 703, the movement reliability and connection stability of the mounting plate 10 or the swing rod 50 and the piercing rod 40 are enhanced, the movement wear problem of the moving parts of the mechanical structure due to the entry of material dust is avoided, and the service life of the mounting plate 10 or the swing rod 50 and the piercing rod 40 is extended; on the other hand, the metal powder generated by the movement wear between the mounting plate 10 or the swing rod 50 and the piercing 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, during the process of puncturing or hanging the ton bag by the piercing rod 40, 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 at least part of the second protective cover 72 can be deformed to improve the sealing between the second protective cover 72 and the piercing rod 40, and to 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, so as to facilitate the assembly of the second protective cover 72 and the mounting plate 10. The cover 722 is installed in the cover shell 721, and forms a second mounting cavity 703 with the cover shell 721 and the mounting plate 10. The cover shell 721 is configured as a rigid mechanism, the cover 722 is configured as an elastic structure or a telescopic structure, and a position avoidance hole 704 is provided to match the piercing rod 40. Therefore, the rigidity of the cover shell 721 can avoid the problem of damage to the cover 722 due to the squeezing of the ton bag, prolong the service life of the second protective cover 72, and improve the sealing performance of the second mounting cavity 703, prevent the material from entering the second mounting cavity 703, and prevent the 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 as a whole. In some other embodiments, the second protective cover 72 can also be configured as a rigid structure as a whole, and an elastic seal is provided between the cover 722 and the puncture rod 40 to achieve the sealing function and the rotation function of the puncture rod 40.

[0079] In this embodiment, the bottom of the cover shell 721 is extended 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 cover shell 721 away from the mounting plate 10 and the cover 722. As a result, when the piercing rod 40 pierces or hangs the ton bag, the cover shell 721 first contacts the ton bag, thereby avoiding the problem of the cover 722 being squeezed by the ton bag and being damaged, improving the sealing connection between the cover 722, the cover shell 721 and the piercing rod 40, and extending the service life of the second protective cover 72.

[0080] The mounting plate 10 is provided with an active hole 102 connected to the second mounting cavity 703. The piercing rod 40 is movable in the active hole 102, and the second protective cover 72 covers the active hole 102. Thus, on the one hand, the piercing rod 40 is movable in the active hole 102, so that the piercing rod 40 can rotate a preset angle to switch between the piercing state and the hanging state, thereby improving the reliability and smoothness of the rotation of the piercing rod 40; on the other hand, based on the second protective cover 72 covering the active hole 102, the dust generated during the bag breaking process of the ton bag is prevented from entering the second mounting cavity 703, the movement reliability and connection stability of the piercing rod 40 and the connecting rod mechanism 30 are enhanced, and the problem of movement wear of the moving parts of the mechanical structure due to the entry of material dust is avoided, and the service life of the piercing rod 40 and the connecting rod mechanism 30 is extended; on the other hand, the metal powder and debris generated by the movement wear 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 avoiding material pollution and meeting the requirements of product quality and environmental protection.

[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 substantially equal to the radial dimension of the puncturing rod 40, so that the movable hole 102 can guide the rotation of the puncturing rod 40. Of course, in some 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 puncturing rod 40.

[0082] In the present embodiment, the side wall of the second protective cover 72 is further provided with a limiting groove 706. The limiting groove 706 can be provided as one or more. In the present 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, so as to facilitate the processing and manufacturing of the second protective cover 72. Of course, it should be noted that the number and position of the limiting grooves 706 can be provided according to the swinging trajectory of the puncture rod 40 driven by the connecting rod mechanism 30 to perform a swinging motion, and the embodiment of the present application does not make specific limitations. For example, in some embodiments, the side wall 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 piercing rod 40 is inserted into the limiting groove 706. The limiting groove 706 is used to limit the maximum rotation angle of the piercing 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 piercing rod 40 can be extended into the limiting groove 706. Therefore, when the piercing rod 40 rotates to the maximum rotation angle, the piercing rod 40 and the bottom wall of the limiting groove 706 are limited and stopped, thereby avoiding the problem that the ton bag is punctured in the hanging state due to the excessive rotation angle of the piercing rod 40, thereby improving the safety of the ton bag hanging device 100.

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