However, the above description is for the purpose of illustrating the general principles of the present invention and is not intended to limit the scope of the present invention. The scope of protection of the present invention shall be determined by the appended claims.

[0034] Please also refer to Figure 1 and Figure 2 , Figure 1 It is a partial cross-sectional view of a ton bag conveying device 100 provided in an embodiment of the present utility model; Figure 2 yes Figure 1Schematic diagram of the structure of the ton bag conveying device 100 in FIG. The ton bag conveying device 100 includes a clamping mechanism 10, a lifting mechanism 30, and a translation mechanism 50. The clamping mechanism 10 is used to clamp ton bags. The lifting mechanism 30 is disposed on one side of the clamping mechanism 10 in the height direction Z of the ton bag conveying device 100 and is used to drive the clamping mechanism 10 to move in the height direction Z of the ton bag conveying device 100. The translation mechanism 50 is disposed on the side of the lifting mechanism 30 in the height direction Z of the ton bag conveying device 100 that is away from the clamping mechanism 10 and is used to drive the clamping mechanism 10 and the lifting mechanism 30 to move in the length direction X of the ton bag conveying device 100.

[0035] The ton bag conveying device 100 provided in the embodiment of the present invention is based on arranging the clamping mechanism 10 on the side of the lifting mechanism 30 facing away from the translation mechanism 50, thereby avoiding interference between the ton bag and the lifting mechanism 30 and the translation mechanism 50, facilitating the transportation of the ton bag, and improving the conveying efficiency of the ton bag.

[0036] It should be noted that 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 substances, powdered substances, and block substances. 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 ton bags are not limited here. For example, in an embodiment of the present utility model, ton bags are used to load battery materials. Battery materials include but are not limited to positive electrode materials, negative electrode materials, conductive agents or dispersants, etc.; alternatively, various materials are mixed to form battery mixture materials.

[0037] It should be noted that Figure 1 The purpose is only to schematically describe the arrangement of the clamping mechanism 10, the lifting mechanism 30 and the translation mechanism 50, and is not to make specific limitations on the connection position, connection relationship and specific structure of each component. Figure 1 The structure of the ton bag conveying device 100 is only shown in the embodiment of the present invention, and does not constitute a specific limitation on the ton bag conveying device 100. In other embodiments of the present invention, the ton bag conveying device 100 may include Figure 1 More or fewer components, or combinations of certain components, or different components, such as the ton bag conveying device 100 may also include but are not limited to sensors, etc. For example, the sensor may be used to detect whether the clamping mechanism 10 has clamped a ton bag.

[0038] For the accuracy of description, please refer to the direction in this article. Figure 2For reference, "length direction X" refers to the direction in which the translation mechanism 50 drives the ton bag to translate, that is, the left-right direction (where the positive direction of the X axis is left); the term "width direction Y" refers to the opening and closing direction of the first clamping jaw 161 and the second clamping jaw 162 in the clamping mechanism 10, that is, the front-to-back direction (where the positive direction of the Y axis is rear); the term "height direction Z" refers to the direction in which the lifting mechanism 30 drives the ton bag to lift and lower, that is, the up-down direction (where the positive direction of the Z axis is up), wherein the length direction X, the width direction Y and the height direction Z together constitute the three orthogonal directions of the ton bag conveying device 100. The length direction X, the width direction Y and the height direction Z of the ton bag conveying device 100 can be customized according to the specific structure of the product and the perspective of the drawings, and this utility model does not make specific limitations. For the convenience of description, the directions such as up, down, left, right, front and back in this utility model are relative positions and do not constitute a limitation on implementation.

[0039] In some embodiments, the ton bag conveying device 100 further includes a lifting guide mechanism 40. The lifting guide mechanism 40 includes a guide rod 41 and a connecting rod component 42. One end of the guide rod 41 is connected to the translation mechanism 50. The connecting rod component 42 is disposed at the end of the guide rod 41 facing away from the translation mechanism 50 and is connected to the clamping mechanism 10. Thus, the lifting guide mechanism 40 can guide the clamping mechanism 10 and the ton bag it is gripping during lifting and lowering, enabling the ton bag to be lifted and lowered in a specified direction, thereby improving the stability and reliability of the ton bag lifting process.

[0040] Please also refer to Figure 2 and Figure 3 , Figure 3 yes Figure 1 Schematic diagram of the structure of the lifting guide mechanism 40 of the ton bag conveying device 100 in FIG. In some embodiments, the lifting guide mechanism 40 further includes a limiter 43. The limiter 43 is provided at the end of the guide rod 41 facing away from the translation mechanism 50, and is used to limit the connecting rod component 42 between the translation mechanism 50 and the limiter 43. Thus, the provision of the limiter 43 can prevent the connecting rod component 42 from sliding off the guide rod 41, thereby improving the reliability of the connection between the connecting rod component 42 and the guide rod 41, and avoiding the problem of collision between the connecting rod component 42 and other components of the ton bag conveying device 100 during the sliding process relative to the guide rod 41, thereby improving the safety of the connecting rod component 42. The limiter 43 is provided independently of the guide rod 41 and is detachably fixedly connected to the guide rod 41, thereby facilitating the assembly efficiency of the connecting rod assembly and the guide rod 41. Specifically, the limiter 43 is locked to the guide rod 41 by a locking structure, thereby facilitating the assembly of the limiter 43 and the guide rod 41. Of course, in some embodiments, the limiting member 43 may also be integrally formed with the guide rod 41 .

[0041] The limiting member 43 can be configured as an annular structure. The limiting member 43 is provided with a notch along the circumferential direction of the limiting member 43 so that the limiting member 43 is disconnected, thereby facilitating the positioning of the limiting member 43 on the guide rod 41, thereby improving the assembly efficiency between the limiting member 43 and the guide rod 41. Specifically, the limiting member 43 is provided with a locking structure at the notch, and the inner diameter of the limiting member 43 is adjusted by the locking structure so that the limiting member 43 is sleeved on the outer side of the guide rod 41. The annular structure can be an elastic ring or a rigid ring. Of course, in some other embodiments, the limiting member 43 can also be configured as a closed annular structure; or, it can be configured as a protruding structure protruding relative to the guide rod 41; or, it can be configured as a rod-shaped structure, such as a pin. The structure and connection method of the limiting member 43 are not specifically limited in the present invention, and any structure that can stop the connecting rod component 42 in the height direction of the guide rod 41 is applicable to this application.

[0042] Please also refer to Figure 3 and Figure 4 , Figure 4 yes Figure 1 Schematic diagram of the structure of the clamping mechanism 10 and part of the lifting guide mechanism 40 of the ton bag conveying device 100. The connecting rod component 42 includes a bearing seat 421, a first rod 422 and a second rod 423. The clamping mechanism 10 includes a support plate 11, a clamping drive 15, a first clamping jaw 161 and a second clamping jaw 162. The clamping drive 15 is arranged on the support plate 11 to drive the first clamping jaw 161 and the second clamping jaw 162 to move closer to or away from each other. One end of the first rod 422 is hinged to the bearing seat 421, and the other end is hinged to the first clamping jaw 161. One end of the second rod 423 is hinged to the bearing seat 421, and the other end is hinged to the second clamping jaw 162. The first rod 422 and the second rod 423 are symmetrically arranged relative to the guide rod 41, and the first rod 422 and the second rod 423 are tilted relative to the guide rod 41. Thus, on the one hand, because the first rod 422 and the second rod 423 are symmetrically arranged relative to the guide rod 41, the first clamping jaw 161 and the second clamping jaw 162 can move symmetrically, ensuring that the clamping mechanism 10 is evenly stressed when clamping the ton bag, thereby improving the reliability and stability of the clamping mechanism 10 in clamping the ton bag and extending the service life of the clamping mechanism 10. On the other hand, the clamping drive 15 can be programmed to perform frequent and instantaneous extension and retraction movements according to program-controlled parameters when the first and second clamping jaws 161 and 162 clamp the ton bag. Due to the multiple and rapid extension and retraction movements of the clamping drive 15, the first and second clamping jaws 161 and 162 form a slapping motion similar to that of the ton bag, making it easier to unload material adhering to the inner bag of the ton bag, thereby assisting in unloading and improving the unloading effect and efficiency of the ton bag. Specifically, the first rod 422 and the second rod 423 are hingedly connected to the bearing seat 421 via a hinge shaft. Specifically, a side wall of the bearing seat 421 is provided with a pivot lug, and the first rod 422 and the second rod 423 are respectively hinged to the lug via a hinge axis.

[0043] For example, in this embodiment, two gripping drive members 15 are provided, each connected between the first clamping jaw 161 and the second clamping jaw 162, with the two gripping drive members 15 operating in opposite directions. This improves the uniformity of force applied to the first clamping jaw 161 and the second clamping jaw 162, enhances the reliability and stability of the gripping mechanism 10 in gripping ton bags, and extends the service life of the gripping mechanism 10. Of course, in some embodiments, a single gripping drive member 15 is provided, connected between the first clamping jaw 161 and the second clamping jaw 162. This reduces the number of components, improves the overall compactness of the ton bag conveying device 100, and saves costs.

[0044] In some embodiments, the first clamping jaw 161 and the second clamping jaw 162 each include two clamping arms 163. The connecting rod assembly 42 further includes a first linkage 425 and a second linkage 426. The first linkage 425 is connected between the two clamping arms 163 of the first clamping jaw 161 and is connected to the end of the first rod 422 facing away from the bearing seat 421. The second linkage 426 is connected between the two clamping arms 163 of the second clamping jaw 162 and is connected to the end of the second rod 423 facing away from the bearing seat 421. Thus, the addition of the linkage facilitates the assembly and connection between the first rod 422 and the first clamping jaw 161, and between the second rod 423 and the second clamping jaw 162, thereby improving the stability and reliability of the connection and achieving a reasonable and compact structural layout. Of course, in some embodiments, the first linkage 425 and the second linkage 426 may be omitted, that is, the first rod 422 is directly hinged to the clamping arms 163 of the first clamping jaw 161, and the second rod 423 is directly hinged to the clamping arms 163 of the second clamping jaw 162.

[0045] For example, in this embodiment, the first clamping jaw 161 and the second clamping jaw 162 each further include a transmission arm 1631. One end of the transmission arm 1631 is fixedly connected to the clamping arm 163, and the other end of the transmission arm 1631 is hingedly connected to the clamping drive 15. This facilitates assembly of the transmission arm 1631 with the clamping drive 15. The end of the clamping arm 163 near the clamping drive 15 is provided with a slot 1630 for engaging the transmission arm 1631, thereby improving the reliability of the connection between the clamping arm 163 and the transmission arm 1631. Of course, in some embodiments, the transmission arm 1631 may be omitted.

[0046] The number of first rods 422 and second rods 423 each includes two, thereby improving the smoothness of the swinging of the first clamping jaw 161 and the second clamping jaw 162. It should be noted that the number of clamping arms 163, the number of first rods 422, and the number of second rods 423 are for illustrative purposes only and are not specifically limited in the present embodiment. For example, the first clamping jaw 161 and the second clamping jaw 162 may each include one or more clamping arms 163. The number of first rods 422 and second rods 423 may also include one or two.

[0047] In some embodiments, there are multiple guide rods 41 and bearing blocks 421, each of which is connected to a corresponding bearing block 421. The connecting rod assembly 42 also includes a connecting arm 427, which is connected between two adjacent bearing blocks 421. Thus, the connecting arm 427 connects two adjacent bearing blocks 421. This, on the one hand, achieves synchronized movement of the two clamping arms 163, improves force uniformity between the first and second clamping jaws 161 and 162, enhances the reliability and stability of the clamping mechanism 10 in clamping ton bags, and prolongs the service life of the clamping mechanism 10; on the other hand, it improves the compactness and connection reliability of the various components of the connecting rod assembly 42. In some embodiments, the connecting arm 427 can be omitted. For example, the two bearing blocks 421 can be integrated into a single piece; alternatively, the two bearing blocks 421 can be independently provided and fixedly connected via a mounting block; or alternatively, the two bearing blocks 421 can be independently provided.

[0048] The lifting mechanism 30 includes a lifting drive 31 and a lifting rod 32. The lifting drive 31 is used to drive the lifting rod 32 to extend and retract along the height direction Z of the ton bag conveying device 100. Thus, the lifting mechanism 30 can drive the clamping mechanism 10 to perform lifting and lowering motion relative to the guide rod 41 in the height direction Z of the ton bag conveying device 100. On the one hand, the flexibility of the clamping mechanism 10 in clamping ton bags is improved, and processes such as clamping and puncturing of ton bags are realized. For example, in this embodiment, the lifting mechanism 30 is configured as a lifting electric cylinder, thereby improving the stability of the lifting and lowering motion of the clamping mechanism 10, preventing the ton bags clamped by the clamping mechanism 10 from shaking, ensuring the uniformity of the ton bag breaking position, and improving the material unloading rate. Of course, in some embodiments, the lifting mechanism 30 can also be configured as, but not limited to, a gear rack structure or a lifting cylinder.

[0049] In this embodiment, the lifting rod 32 and the guide rod 41 are arranged side by side. This facilitates assembly, maintenance, and replacement of the lifting mechanism 30 and the lifting guide mechanism 40, and improves the overall compactness of the bulk bag conveying device 100. Of course, in some embodiments, the lifting rod 32 is inserted into the guide rod 41; alternatively, the lifting rod 32 and the guide rod 41 are arranged in an offset manner.

[0050] Please also refer to Figure 4 and Figure 5 , Figure 5 yes Figure 1 A cross-sectional view of the ton bag conveying device 100 in the first state. For example, in this embodiment, the clamping mechanism 10 further includes a support plate 11 and a pivot seat 12. The pivot seat 12 is disposed on the side of the support plate 11 facing the translation mechanism 50. The first clamping jaw 161 and the second clamping jaw 162 are both pivotally connected to the pivot seat 12 via a pivot shaft 13. The clamping drive 15 is disposed on the support plate 11 and is used to drive the first clamping jaw 161 and the second clamping jaw 162 to rotate about the pivot shaft 13 so that the first clamping jaw 161 and the second clamping jaw 162 move closer to or away from each other. The ton bag conveying device 100 further includes a first protective cover 61, which is connected to the support plate 11 to form an installation cavity 6101. The pivot seat 12, the clamping drive 15, a portion of the first clamping jaw 161, a portion of the second clamping jaw 162, and a portion of the lifting guide mechanism 40 are disposed within the installation cavity 6101. Therefore, the first protective cover 61 can seal the structural elements arranged on the top of the support plate 11. 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 clamping mechanism 10, the lifting mechanism 30 and the lifting guide mechanism 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; on the other hand, the metal powder and debris generated by the movement wear of the clamping mechanism 10, the lifting mechanism 30 and the lifting guide mechanism 40 cannot enter the material, thereby avoiding material pollution and meeting the requirements of product quality and environmental protection.

[0051] For example, in this embodiment, the first protective cover 61 can be configured as a rigid structure, so as to facilitate the assembly of the first protective cover 61 and the support plate 11, and avoid the problem of deformation of the first protective cover 61 and movement interference with the components in the installation cavity 6101. The rigidity of the first protective cover 61 can provide support and installation sites for other components. The first protective cover 61 includes a first cover body 611 and a second cover body 612. The first cover body 611 and the second cover body 612 are independently provided and fixedly connected to each other, so as to facilitate the assembly, maintenance, replacement and other operations of the first protective cover 61 and the support plate 11. Of course, in some embodiments, the first cover body 611 and the second cover body 612 can also be integrally formed, which is not specifically limited in the embodiment of the present utility model.

[0052] The central axis of the pivot shaft 13 is perpendicular to the width direction Y and the height direction Z of the ton bag conveying device 100, thereby enabling the first clamping jaw 161 and the second clamping jaw 162 to move toward or away from each other about the central axis of the pivot shaft 13 along the length direction X of the ton bag conveying device 100. In some embodiments, a bearing is provided on the pivot seat 12, and the pivot shaft 13 is rotatably disposed within the bearing. This reduces rotational resistance of the first clamping jaw 161 and the second clamping jaw 162, prevents distortion of the first clamping jaw 161 and the second clamping jaw 162 during movement toward or away from each other, and reduces wear between the pivot seat 12, the pivot shaft 13, the first clamping jaw 161, and the second clamping jaw 162, thereby increasing their service life.

[0053] In some embodiments, the lifting guide mechanism 40 also includes a fixed plate 45 and a bearing 46. The fixed plate 45 is sealed and connected to the first protective cover 61. The fixed plate 45 is provided with a first avoidance hole 4501 and a second avoidance hole 4502. The bearing 46 is provided at the first avoidance hole 4501 and is sleeved on the guide rod 41. The lifting mechanism 30 is passed through the second avoidance hole 4502 and covers the second avoidance hole 4502. Thus, on the one hand, the fixed plate 45 is connected to the guide rod 41 through the bearing 46, thereby improving the smoothness of the lifting and lowering movement of the clamping mechanism 10 and improving the sealing performance of the installation cavity 6101; on the other hand, the setting of the second avoidance hole 4502 realizes the lifting and lowering movement of the lifting mechanism 30, and the lifting mechanism 30 covers the second avoidance hole 4502 to improve the sealing performance of the installation cavity 6101, thereby improving the stability and reliability of the mechanical movement of each component, and meeting the requirements of product quality and environmental protection. Of course, in some embodiments, the fixing plate 45 may be omitted, that is, the first avoidance hole 4501 and the second avoidance hole 4502 are provided on the top wall of the first protective cover 61 .

[0054] In some embodiments, the lifting guide mechanism 40 further includes a sealing gasket 47. The sealing gasket 47 is disposed between the fixing plate 45 and the first protective cover 61, thereby improving the sealing performance of the mounting cavity 6101, improving the stability and reliability of the mechanical movement of each component, and meeting the requirements of product quality and environmental protection.

[0055] In some embodiments, the ton bag conveying device 100 further includes a second protective cover 62, one end of which is connected to the translation mechanism 50, and the other end of which is connected to the first protective cover 61 and / or the fixed plate 45. The second protective cover 62 is used to cover the lifting mechanism 30 and the lifting guide mechanism 40 located outside the first protective cover 61. The second protective cover 62 is configured as a telescopic structure or an elastic structure. Thus, the second protective cover 62 can seal the structural elements located on top of the fixed plate 45. On the one hand, dust generated during the ton bag breaking process cannot enter the moving hinges, thereby enhancing the movement reliability and connection stability of the clamping mechanism 10, the lifting mechanism 30, and the lifting guide mechanism 40, preventing the moving parts of the mechanical structure from wearing out due to the ingress of material dust, and extending their service life. On the other hand, metal powder and debris generated by the wear of the lifting mechanism 30 and the lifting guide mechanism 40 located outside the first protective cover 61 cannot enter the material, thereby preventing material contamination and meeting the requirements of product quality and environmental protection. Illustratively, in this embodiment, the second protective cover 62 is configured as an accordion cover with a telescopic function, so that the second protective cover 62 can be stretched following the lifting and lowering of the lifting mechanism 30 , thereby improving the smoothness and stability of the movement of the lifting mechanism 30 .

[0056] Please refer again Figure 2 and Figure 4 , exemplarily, in this embodiment, the first clamping jaw 161 and the second clamping jaw 162 each further include a connecting arm 164. One end of the clamping arm 163 is transmission-connected to the clamping drive member 15, and the other end of the clamping arm 163 is staggeredly connected to the connecting arm 164. The support plate 11 is provided with a movable hole 1101. The clamping arm 163 can be movably inserted into the movable hole 1101, and the ton bag conveying device 100 further includes a third protective cover 63. The third protective cover 63 is fixedly connected to the support plate 11, and is used to cover the portion of the clamping arm 163 located outside the first protective cover 61 and close to the connecting arm 164. The third protective cover 63 is configured as a telescopic structure or an elastic structure. Therefore, on the one hand, the third protective cover 63 can prevent material from entering the first protective cover 61 from the third protective cover 63, thereby enhancing the movement reliability and connection stability of the moving parts of the mechanical structure, 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. At the same time, it ensures that the first clamping jaw 161 and the second clamping jaw 162 can move closer to or away from each other; on the other hand, the metal powder and debris generated by the movement wear of the moving parts of the mechanical structure cannot enter the material, thereby avoiding material contamination and meeting the requirements of product quality and environmental protection.

[0057] The second protective cover 62 and the third protective cover 63 are both configured as flexible structures. Specifically, the second protective cover 62 and the third protective cover 63 can be made of at least one of polyurethane coated fabric and polyvinyl chloride coated fabric, thereby improving the wear resistance, chemical resistance, aging resistance, etc. of the second protective cover 62 and the third protective cover 63, and extending the service life of the second protective cover 62 and the third protective cover 63. The third protective cover 63 is fixed on the support plate 11 and covers the movable hole 1101, thereby avoiding the problem of movement wear of the moving parts of the mechanical structure due to the entry of material dust, extending the service life, and preventing the metal powder and debris generated by the movement wear of the moving parts of the mechanical structure from entering the material, avoiding material contamination, and meeting the requirements of product quality and environmental protection. Specifically, one end of the third protective cover 63 is sealed with the support plate 11, and the other end of the third protective cover 63 is sealed with the clamping arm 163.

[0058] In this embodiment, the connecting arm 164 is configured as an arc-shaped arm, and its shape matches the shape of the ton bag. As a result, after the clamping mechanism 10 clamps the ton bag, the shape of the connecting arm 164 matches the shape of the ton bag, thereby increasing the clamping area between the connecting arm 164 and the ton bag. This also allows for better adaptation to the deformation of the ton bag, allowing for a wider range of gripping of the ton bag, making the clamping mechanism 10 more stable and reliable in clamping the ton bag. Specifically, the connecting arm 164 includes a first arc-shaped segment 1643 and two second arc-shaped segments 1644 connected to each end of the first arc-shaped segment 1643. The curvature of the first arc-shaped segment 1643 is opposite to that of the second arc-shaped segment 1644. This enhances the overall structural strength of the connecting arm 164 and improves the reliability and stability of the first and second clamping jaws 161 and 162 in clamping the ton bag.

[0059] In some embodiments, the first clamping jaw 161 and the second clamping jaw 162 each further include a reinforcing rib 165. The connecting arm 164 includes a clamping surface 1641 and a connecting surface 1642 opposite to the clamping surface 1641. The reinforcing rib 165 is disposed on the connecting surface 1642 and connected to the clamping arm 163. Thus, the provision of the reinforcing rib 165 can enhance the overall structural strength of the first clamping jaw 161 and the second clamping jaw 162, thereby extending the service life of the first clamping jaw 161 and the second clamping jaw 162.

[0060] In some embodiments, the first clamping jaw 161 and the second clamping jaw 162 each further include an extension arm 166 . The extension arm 166 is disposed on the clamping surface 1641 of the connecting arm 164 . Multiple extension arms 166 are provided, with each of the first clamping jaw 161 and the second clamping jaw 162 being provided with an extension arm 166 at both ends in the width direction Y of the ton bag conveying device 100 . Thus, the multiple extension arms 166 , the connecting arm 164 , and the support arm form a clamping space 160 for defining a ton bag. The ton bag is located within the clamping space 160 , thereby improving the reliability and stability of the clamping mechanism 10 in clamping the ton bag.

[0061] Please refer again Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , Figure 6 yes Figure 1 A top view of the translation mechanism 50 of the ton bag conveying device 100; Figure 7 yes Figure 6 A cross-sectional view of the translation mechanism 50 of the ton bag conveying device 100 along line AA in FIG. The translation mechanism 50 includes a support beam 51, a translation driver 53, and a slider 54. The slider 54 is movably mounted on the support beam 51. The lifting mechanism 30 and the guide rod 41 are both mounted on the slider 54, thereby enabling the ton bag gripped by the clamping mechanism 10 to slide along the longitudinal direction X of the ton bag conveying device 100. Specifically, the slider 54 includes a mounting plate 541, a gear 542, and a rack 543. The mounting plate 541 is movably mounted on the support beam 51. The lifting mechanism 30 is mounted on the mounting plate 541. The translation driver 53 is in transmission connection with the gear 542. The rack 543 is fixed to the support beam 51 and meshes with the gear 542. The translation driver 53 is used to drive the gear 542 to rotate, thereby driving the mounting plate 541, the lifting mechanism 30, and the clamping mechanism 10 to move along the longitudinal direction X of the ton bag conveying device 100. As a result, the translation drive member 53 drives the gear 542 to rotate at an angular velocity and move in a straight line at a linear velocity relative to the rack 543, thereby improving the stability and reliability of the movement of the mounting plate 541 together with the lifting mechanism 30 and the clamping mechanism 10 along the length direction X of the ton bag conveying device 100, so that the translation mechanism 50 has the characteristics of simple structure, long service life, stable operation, high reliability, etc., and prevents the ton bags clamped by the clamping mechanism 10 from shaking, ensures the uniformity of the bag breaking position of the ton bags, and improves the material unloading rate.

[0062] One end of the lifting mechanism 30 is hinged to the mounting plate 541, and the other end of the lifting mechanism 30 is fixedly connected to the support plate 11, thereby improving the reliability of the connection between the lifting mechanism 30, the translation mechanism 50, and the clamping mechanism 10. Specifically, one end of the lifting mechanism 30 is hinged to the mounting plate 541 via a joint bearing, and the other end of the lifting mechanism 30 is fixedly connected to the support plate 11 via a flange seat.

[0063] In some embodiments, the support beam 51 includes a first guide beam 511 and / or a second guide beam 512. A buffer structure 52 is provided at at least one end of the first guide beam 511 and / or the second guide beam 512. The buffer structure 52 is used to stop the sliding member 54. As a result, the buffer structure 52 can mechanically limit the sliding of the sliding member 54, preventing the sliding member 54 from detaching from the first guide beam 511 and the second guide beam 512 due to inertia, thereby improving the safety of the ton bag conveying device 100. For example, in this embodiment, a buffer structure 52 is provided at both ends of the first guide beam 511 and both ends of the second guide beam 512. The buffer structure 52 can be configured as an elastic structure or a telescopic structure to absorb the impact force of the sliding member 54 and reduce the risk of damage to the sliding member 54.

[0064] In some embodiments, the translation mechanism 50 further includes a guide slide 55. The guide slide 55 includes a first guide slide portion 551 and a second guide slide portion 552. The first guide slide portion 551 is fixed to the support beam 51, and the second guide slide portion 552 is fixed to the slider 54 and slidably engages with the first guide slide portion 551. Thus, the provision of the guide slide 55 can improve the smoothness and stability of the sliding of the slider 54 relative to the support beam 51, thereby enabling the translational transportation of the ton bag gripped by the gripping mechanism 10, thereby preventing the ton bag gripped by the gripping mechanism 10 from shaking, ensuring the uniformity of the ton bag breaking position, and improving the material unloading rate.

[0065] Specifically, for example, in this embodiment, one of the first guide slide 551 and the second guide slide 552 is configured as a slider, and the other of the first guide slide 551 and the second guide slide 552 is configured as a slide rail that slidably cooperates with the slider. Of course, in some embodiments, one of the first guide slide 551 and the second guide slide 552 is configured as a roller, and the other of the first guide slide 551 and the second guide slide 552 is configured as a raceway that slidably cooperates with the roller.

[0066] Please also refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 8 , Figure 8 yes Figure 1: A cross-sectional view of the ton bag conveying device 100 in the second state. For example, in this embodiment, the first state refers to the initial state in which the clamping mechanism 10 does not clamp the ton bag, that is, the state in which the first clamping jaw 161 and the second clamping jaw 162 are far away from each other. The second state refers to the state in which the clamping mechanism 10 is clamping the ton bag, that is, the state in which the first clamping jaw 161 and the second clamping jaw 162 are close to each other. The translation drive member 53 in the translation mechanism 50 is started to translate the clamping mechanism 10, the lifting mechanism 30 and the lifting guide mechanism 40 to the first station, and the translation drive member 53 stops moving. The lifting drive member 31 in the lifting mechanism 30 is started to drive the lifting rod 32 to extend outward to lower the clamping mechanism 10 downward to the clamping station (that is, the position in which the clamping mechanism 10 clamps the ton bag). It should be noted that, in the initial state, the lifting rod 32 is in a retracted state, and the clamping mechanism 10 is in the highest position. The gripping drive 15 in the gripping mechanism 10 is activated to drive the first and second gripping jaws 161, 162 to extend outward, bringing the first and second gripping jaws 161, 162 closer together to grip the ton bag. The lifting drive 31 retracts the lifting rod 32 inward to lift the gripping mechanism 10 and the ton bag gripped by the gripping mechanism 10 to the second station (i.e., a position where the gripping mechanism 10 can be translated to the bag breaking and unloading station). At this point, the gripping drive 15 drives the first and second gripping jaws 161, 162 to maintain a firm grip on the ton bag. The translation drive 53 in the translation mechanism 50 is activated to translate the gripping mechanism 10 and the ton bag gripped by the gripping mechanism 10 to the third station (i.e., the bag breaking and unloading station). Then, the lifting drive 31 in the lifting mechanism 30 is activated again to drive the lifting rod 32 to extend, driving the gripping mechanism 10 and the ton bag gripped by the gripping mechanism 10 to the tool position for bag breaking. The lifting drive 31 then stops. During the unloading process, the gripping drive 15 operates again, repeatedly and rapidly extending and retracting the first and second gripping jaws 161 and 162 to create a flapping motion to assist in unloading. After unloading is complete, the next transport and gripping cycle continues. During this process, the first, second, and third protective covers 61, 62, 63 seal the mechanical moving components of each mechanism of the ton bag conveyor 100, preventing material from contaminating the material and preventing material from entering the mechanical moving components. This enhances the reliability and connection stability of the mechanical moving components, prevents wear and tear caused by the ingress of material dust, and extends their service life.
