[0002] At present, flat car loading system mainly includes portal frame along ground rail walking, and clamping mechanism for clamping material installed on portal frame. So as to move to goods location by portal frame, and after only clamping material by clamping mechanism, then move to corresponding position of flat car to unload and load.

[0003] However, in actual loading process, for large-tonnage ton bag material, clamping mechanism not only needs to be suspended and carried ton bag between flat car and vertical warehouse storing ton bag back and forth, but also needs to be transversely moved to corresponding position of flat car to unload, that is, clamping mechanism needs to clamp large-tonnage ton bag for a long time and move in suspension, this handling mode can cause ton bag to slide down or even fall off during suspension movement, and if the holding force is excessively strengthened, ton bag can be damaged, and this handling mode needs to be waited for a long time after the first bag before each ton bag is loaded in front of flat car, and handling efficiency is very low.

[0004] Therefore, the high-efficiency feeding equipment for flat car loading system is designed to solve the above problems. INVENTION CONTENTS

[0015] Furthermore, the lateral movement drive device includes a support frame and a lateral movement motor mounted on the support frame. The clamping mechanism includes a lateral movement frame that is slidably mounted on the support frame and driven to move back and forth by the lateral movement motor, a lifting frame that is slidably connected to the lateral movement frame, a plurality of lifting cylinders that are connected between the lateral movement frame and the lifting frame and are used to drive the lifting frame to move up and down, and a clamping device located on the front side of the lifting frame. The clamping device is provided in a plurality of units and is distributed at progressively higher and lower intervals. Each clamping device includes a drive seat fixed on the front side of the lifting frame, two clamping members that are slidably connected to the drive seat by sliding members and are corresponding to each other, and a clamping cylinder located on the drive seat and used to drive the two clamping members to move toward each other or in opposite directions.

[0019] The beneficial effects of this utility model are:

[0020] 1. By adding a material-combining mechanism, in conjunction with the handling mechanism of the loading system, single-row material-combining loading of ton bags can be performed, improving the feeding and loading efficiency of the feeding equipment. Based on this, through the setting of the feeding conveyor line and clamping positions, several materials are fed one by one between the clamping mechanism and the material-combining platform. The clamping mechanism can then coaxially move laterally to clamp several materials one by one onto several material-combining positions to form combined materials. The material-combining platform then rotates and connects to the loading device of the handling mechanism. This linear clamping method of the clamping mechanism onto the material-combining platform maximizes material-combining efficiency, thereby improving the feeding efficiency of the feeding equipment and allowing the combined materials to be quickly formed. The corresponding material loading device is rotated and assembled, enabling the above-mentioned material loading method to be implemented quickly. At the same time, the above-mentioned material loading method and the material loading method can shorten the stroke of the clamping mechanism to clamp the ton bag material and move it in the air. The long stroke clamping of the existing handling method, in which the clamping mechanism needs to clamp the ton bag material and move it back and forth to the flatbed and then left and right to the loading position, is replaced by the short stroke clamping of the clamping mechanism, which only needs to clamp the ton bag material and move it from the clamping position to the material loading platform. This can avoid the risk of large ton bags sliding, shifting or falling during the clamping and suspended movement, greatly improving the stability of clamping and handling, and thus improving the stability of subsequent material loading.

[0021] 2. Palletized materials alternately transported from the automated storage and retrieval system to the two feeding conveyors can be fed alternately towards the clamping positions in coordination with the reciprocating clamping frequency of the clamping mechanism. This allows the clamping positions to begin feeding during the clamping mechanism's reset process, significantly reducing the waiting time after the clamping mechanism resets. This, in turn, shortens the waiting time of subsequent material handling and conveying mechanisms, increasing the working cycle time of the feeding and clamping mechanisms and improving the feeding efficiency of ton-bag materials. Furthermore, by arranging the two feeding conveyors and one discharging conveyor in an E-shape, with the lateral movement space of the clamping mechanism and the discharging conveyor stacked vertically and forming a discharge gap, the ton-bag material feeding and pallet discharging tasks can be completed, achieving the loading effect of separating materials from pallets before loading onto vehicles. This also improves the feeding efficiency of ton-bag materials. Under these conditions, the structural compactness of the feeding and clamping mechanisms is improved, reducing the overall footprint of the loading system and enhancing the practicality and adaptability of the loading system installation.

[0022] 3. By adding an infeed docking conveyor group, the docking of palletized materials between the infeed conveyor device and the infeed conveyor belt group is realized. The infeed conveyor belt group also realizes the turning and conveying of palletized materials, replacing the docking method of using rotating conveyor rollers to support materials and turn them before inputting them into the next turning conveyor line in the existing technology. This can significantly improve the feeding speed of ton bag materials. Furthermore, by adding an outfeed docking conveyor group, the docking of pallets between the de-pallet conveyor belt group and the outfeed conveyor device is realized, which can significantly improve the pallet discharge efficiency. The infeed docking conveyor group and the outfeed docking conveyor group are respectively raised and lowered in the corresponding infeed conveyor belt group and de-pallet conveyor belt group. Under the premise of realizing docking function, the structural compactness of the infeed conveyor line and the outfeed conveyor line is improved, and the footprint of the two is reduced.

[0023] 4. By inserting several forks into the material handling gap and lifting them, the material on the material handling platform can be quickly lifted, which greatly improves the material discharge efficiency and thus improves the loading efficiency of the material. By adding a sliding frame, the material sliding platform can not only slide to the corresponding clamping position to further shorten the stroke of the clamping mechanism for suspended material movement and improve the stability of clamping and handling, but also allows the material sliding on the platform to rotate 90° laterally to several material picking gaps with several forks coaxially aligned. Then, the sliding frame can quickly move forward to insert several forks into several material picking gaps, allowing the lifting drive assembly to drive the loading device to rise and lift the material sliding through several forks. This eliminates the need for the handling mechanism to move back and forth laterally to connect the loading device to the material sliding platform, shortening the lateral travel of the handling mechanism, reducing costs, and further improving the efficiency of material output to the loading device. Furthermore, the rolling support of several support wheels not only increases the support strength of the material sliding platform but also improves the smoothness of its lateral rotation, preventing it from jamming due to heavy loads and improving its stability when connected to the loading device after rotation.

[0024] 5. By setting up several clamping devices, the clamping mechanism clamps the material on the outside of the material through several clamping parts with vertical spacing, thereby increasing the clamping contact area and improving clamping stability.

[0025] 6. By adding several clamping parts and outward expansion zones, when the two clamping parts of the several clamping devices move towards each other to clamp the material, the material deforms and expands outward to several outward expansion zones after being clamped by several clamping parts. This allows the material to be in a ton bag, where the side is clamped and squeezed by several clamping parts, and then deforms and embeds itself into several outward expansion zones at intervals from top to bottom. This achieves upper and lower limits between the ton bag and the clamping parts, increases the contact area between the clamping parts and the side of the ton bag, reduces the risk of the ton bag deforming and slipping due to the internal product flowing downward towards the center, and thus improves the clamping stability of the ton bag by the clamping device.

[0026] 7. By setting several clamping parts in a stepped shape with gradually increasing height from top to bottom, the cross-section of the outer expansion zone is a trapezoid with a narrow top and a wide bottom. When the material is a ton bag, after its side is clamped and squeezed by several clamping parts, the internal product tends to flow outward and downward into the outer expansion zone. This not only promotes the localized outward expansion deformation of the ton bag side from top to bottom and embeds it into several outer expansion zones, but also avoids the situation where the ton bag side is damaged due to excessive pressure after being clamped. Furthermore, it can gradually increase the depth of the clamping parts embedded in the side of the ton bag from top to bottom, thereby gradually increasing the support force of the clamping parts on the side of the ton bag from top to bottom, and further avoiding the risk of the ton bag deforming and sliding down.

[0027] 8. By adding two bottom supports, when the two clamping parts of several clamping devices move towards each other to clamp the material, the material, after being clamped by several clamping parts, deforms and expands outward to several expansion zones on the sides, and deforms and supports the two bottom supports at the bottom, expanding outward to release pressure to two pressure relief zones. This means that when the material is a ton bag, after being clamped by several clamping parts, not only is the side compressed and deformed outward from top to bottom at intervals, embedding itself into several expansion zones to achieve upper and lower limits between the ton bag and the clamping parts, but the bottom is also compressed and expands outward to the pressure relief zone, supporting the two bottom supports and causing it to rotate downward to a restricted position, thereby expanding the volume of the pressure relief zone and releasing pressure on the lower part of the ton bag. This avoids the risk of rupture due to excessive pressure on the bottom of the ton bag. Simultaneously, by expanding the pressure relief zone, the tendency of the product inside the ton bag to flow outward and downward towards the expansion zone is increased, further enhancing the pressure relief at the bottom of the ton bag. The outward expansion and support of the bottom support reduce the probability of the product inside the ton bag flowing downwards towards the center, avoiding the risk of the ton bag deforming and slipping due to the downward flow of the product inside. This allows the ton bag to deform and fit into several outward expansion and pressure relief zones, further improving the clamping stability of the ton bag by the clamping device. It also prevents the ton bag from becoming unstable on the material stacking platform due to excessive concentration of the product inside after being clamped by the clamping device, thus improving the stability of the ton bag after being clamped onto the material stacking platform and consequently improving the stability of subsequent loading of the ton bags.

[0037] Example 1

[0038] Reference Figures 1-8 As shown, a high-efficiency feeding device for a flatbed truck loading system includes:

[0039] The material feeding mechanism 1 includes a material feeding platform 11 that is driven to rotate laterally by a rotary drive device 12. The material feeding platform 11 includes a discharge structure for discharging material and a plurality of material feeding positions 111 arranged in parallel along the axial direction.

[0040] The feeding mechanism 2 includes a clamping position 21 located on one side of the material feeding platform 11, a feeding conveyor line 22 for inputting materials to the clamping position 21, and a discharging conveyor line 23 for outputting pallets on the clamping position 21; specifically, the material is a ton bag material with a pallet, the feeding end of the feeding conveyor line 22 is connected to the vertical storage outlet conveyor line, and multiple ton bags of material with pallets are stored in the vertical storage.

[0041] The clamping mechanism 3 is driven by the transverse drive device 4 to move coaxially above the material stacking platform 11 and the clamping position 21. The clamping mechanism 3 is used to clamp the material on the clamping position 21 to form a stacked material at several material stacking positions 111.

[0042] Specifically, in addition to the aforementioned high-efficiency feeding equipment, the flatbed truck loading system also includes:

[0043] The conveying mechanism 5 is driven by the walking drive device 6 to move coaxially to the other side of the material stacking platform 11. The conveying mechanism 5 includes a loading device 51 for carrying a plurality of the material stacking materials and a unloading drive device 52 for driving the loading device 51 to unload the material.

[0044] The above structure, through the addition of the material-combining mechanism 1, enables it to cooperate with the conveying mechanism 5 to perform single-row material-combining and loading of ton bags, improving the feeding and loading efficiency of the feeding equipment. Based on this, through the setting of the feeding conveyor line 22 and the clamping positions 21, several materials are fed one by one between the clamping mechanism 3 and the material-combining platform 11. The clamping mechanism 3 can coaxially move laterally to clamp several materials one by one onto several material-combining positions 111 to form combined materials. The material-combining platform 11 then rotates and connects to the loading device 51 of the conveying mechanism 5. Thus, the material-combining method of the clamping mechanism 3 linearly clamping materials onto the material-combining platform 11 maximizes the material-combining efficiency, thereby improving the feeding efficiency of the feeding equipment and the efficiency of the combined materials. The corresponding loading device 51 can be quickly formed and rotated, thereby enabling the above-mentioned material loading method to be implemented quickly. At the same time, the above-mentioned material loading method and the material loading method can together shorten the stroke of the clamping mechanism 3 to clamp the ton bag material and move it in the air. The long stroke clamping of the clamping mechanism 3 in the existing handling method, which requires the clamping mechanism 3 to clamp the ton bag material and move it back and forth to the flatbed and then left and right to the loading position, is replaced by the short stroke clamping of the clamping mechanism 3, which only needs to clamp the ton bag material and move it from the clamping position 21 to the material loading platform 11. This can avoid the risk of large ton bags sliding, shifting or falling during the clamping and suspended movement, greatly improve the stability of clamping and handling, and thus improve the stability of subsequent material loading.

[0045] To improve material feeding efficiency, the material feeding platform 11 extends forward and backward, and the number of material feeding positions 111 is set to two parallel to each other. The conveying mechanism 5 and the clamping mechanism 3 are arranged to move laterally forward and backward. There are two feeding conveyor lines 22, which extend from back to front and then to the clamping position 21. The discharge conveyor line 23 extends forward and backward between the two feeding conveyor lines 22, and the feeding end corresponds to the clamping position 21. The clamping mechanism 3 is gapped above the discharge conveyor line 23 to form a discharge gap. The two feeding conveyor lines 22 are used to alternately feed palletized materials to the clamping position 21. This allows palletized materials alternately transported from the automated storage and retrieval system to the two feeding conveyors 22 to be fed alternately towards the clamping position 21 in coordination with the reciprocating clamping frequency of the clamping mechanism 3. This ensures that the clamping position 21 begins feeding during the resetting process of the clamping mechanism 3, significantly reducing the waiting time after the clamping mechanism 3 resets. This, in turn, shortens the waiting time of the subsequent material handling mechanism 1 and the conveying mechanism 5, increasing the working cycle of the feeding mechanism 2 and the clamping mechanism 3, thereby improving the feeding efficiency of ton-bag materials. Furthermore, by arranging the two feeding conveyors 22 and one discharging conveyor 23 in an E-shape, with the lateral movement space of the clamping mechanism 3 and the discharging conveyor 23 stacked vertically and forming a discharge gap, the feeding and pallet discharging tasks of ton-bag materials are completed, achieving the loading effect of separating materials from pallets before loading onto vehicles. This also improves the feeding efficiency of ton-bag materials. Under these conditions, the structural compactness of the feeding mechanism 2 and the clamping mechanism 3 is improved, reducing the overall footprint of the loading system and enhancing the practicality and adaptability of the loading system installation.

[0046] To improve the structural compactness of the feeding conveyor line 22 and the discharging conveyor line 23, the feeding conveyor line 22 includes two feeding conveying devices 221 for front-to-back conveying, two sets of feeding conveyor belt groups 222 for left-to-right conveying located at the front ends of the two feeding conveying devices 221, two sets of feeding docking conveyor groups 223 for front-to-back conveying and respectively raised and lowered within the two feeding conveyor belt groups 222, and a de-supporting conveyor belt group 224 for left-to-right conveying located between the two feeding conveyor belt groups 222. The discharging conveyor line 23 includes a discharging docking conveyor group 231 for front-to-back conveying and raised and lowered within the de-supporting conveyor belt group 224, and a discharging conveyor group 224 for front-to-back conveying located between the two feeding conveyor belt groups 222. The discharge conveying device 232 is located between the feeding devices 221. The feeding docking conveyor group 223 is used to rise between the feeding conveyor belt group 222 and dock with the feeding conveying device 221. The discharge docking conveyor group 231 is used to rise between the unloading conveyor belt group 224 and dock with the discharge conveying device 232. The two feeding conveying devices 221 and one discharge conveying device 232 are arranged side by side. The clamping position 21 is formed on the unloading conveyor belt group 224. Specifically, the feeding conveying device 221 and the discharge conveying device 232 are both roller conveying devices. The feeding docking conveyor group 223 and the discharge docking conveyor group 231 are both liftable roller conveying devices. Thus, by adding the feeding docking conveyor group 223, the material docking between the feeding conveyor device 221 and the feeding conveyor belt group 222 is realized, and the material is turned and conveyed through the feeding conveyor belt group 222. This replaces the docking method in the prior art, which uses rotating conveyor rollers to support the material and turn it before inputting it into the next turning conveyor line. This can greatly improve the feeding speed of ton bag materials. Furthermore, by adding the discharge docking conveyor group 231, the pallet docking between the pallet removal conveyor belt group 224 and the discharge conveyor device 232 is realized, which can greatly improve the pallet discharge efficiency. The feeding docking conveyor group 223 and the discharge docking conveyor group 231 are respectively raised and lowered in the corresponding feeding conveyor belt group 222 and pallet removal conveyor belt group 224. Under the premise of realizing the docking function, the structural compactness of the feeding conveyor line 22 and the discharge conveyor line 23 is improved, and the footprint of the two is reduced.

[0047] To improve the discharge efficiency of the combined materials, the top of the combining platform 11 includes several support rods 112 arranged side-by-side at intervals. The discharge structure includes several left-right extending material-receiving gaps 113 formed between the support rods 112. The loading device 51 includes several forks 511 extending side-by-side and arranged in a front-back and rear-to-back manner. The unloading drive device 52 includes a lifting drive assembly 521 for driving the loading device 51 to rise and fall. Specifically, the lifting drive assembly 521 is a chain and sprocket lifting device. Thus, by inserting the forks 511 into the material-receiving gaps 113 and lifting them, the combined materials on the combining platform 11 can be quickly lifted, greatly improving the discharge efficiency of the combined materials and consequently increasing the loading efficiency of the materials.

[0048] To further improve the feeding efficiency and loading efficiency of the feeding equipment, the material merging mechanism 1 also includes a sliding frame 13 driven by a sliding drive device 14 to slide back and forth between the clamping position 21 and the loading device 51. The material merging platform 11 is rotatably mounted on the sliding frame 13 via a rotating seat 121. The rotary drive device 12 includes the rotating seat 121 and a swing cylinder 122 for driving the rotating seat 121 to rotate laterally. The bottom of the rotating seat 121 is supported by several support wheels 123 rolling on the top of the sliding frame 13. Specifically, the sliding drive device 14 is a telescopic cylinder. By adding the sliding frame 13, not only can the material-collecting platform 11 slide to the corresponding clamping position 21, further shortening the stroke of the clamping mechanism 3 in the suspended movement of the clamped material and further improving the clamping and handling stability, but also after the material-collecting platform 11 forms and rotates laterally 90° to the front and rear coaxial positions of the forks 511 of the several material-taking gaps 113, it can quickly move forward through the sliding frame 13 to the several forks 511 inserting into the several material-taking gaps 113, so that the lifting drive assembly 521 drives the loading device 51 to rise. The forks 511 lift the material to be stacked, eliminating the need for the conveying mechanism 5 to move back and forth to drive the loading device 51 to dock with the stacking platform 11. This shortens the lateral travel of the conveying mechanism 5, reduces costs, and further improves the efficiency of the material output to the loading device 51. Furthermore, the rolling support of the support wheels 123 not only increases the support strength of the stacking platform 11 but also improves the smoothness of its lateral rotation, preventing it from jamming due to heavy loads and enhancing its stability when docking with the loading device 51 after rotation.

[0049] Specifically, the lateral movement drive device 4 includes a support frame 41 and a lateral movement motor 42 mounted on the support frame 41. The clamping mechanism 3 includes a lateral movement frame 31 slidably mounted on the support frame 41 and driven to move back and forth by the lateral movement motor 42, a lifting frame 32 slidably connected to the lateral movement frame 31, a plurality of lifting cylinders 33 connected between the lateral movement frame 31 and the lifting frame 32 and used to drive the lifting frame 32 to move up and down, and a clamping device 34 located in front of the lifting frame 32. Thus, the lifting frame 32 is driven to rise and fall by the lifting cylinders 33, which in turn drives the clamping device 34 to rise and fall after clamping the material, improving the stability of material removal.

[0050] To improve the clamping stability of the clamping mechanism 3, several clamping devices 34 are provided, arranged at progressively higher and lower intervals. Each clamping device 34 includes a drive seat 341 fixed to the front side of the lifting frame 32, two clamping members 342 that are slidably connected to the drive seat 341 via sliding members 343 and are corresponding to each other, and a clamping cylinder 344 disposed on the drive seat 341 for driving the two clamping members 342 to move towards or away from each other. Thus, by setting up several clamping devices 34, when the clamping mechanism 3 clamps the material, the clamping members 342 arranged at vertical intervals clamp the material to the outside, increasing the clamping contact area and improving clamping stability.

[0051] Specifically, the walking drive device 6 includes a gantry frame 62 that moves laterally back and forth via two parallel ground rails 61. The conveying mechanism 5 includes a base 63 suspended within the gantry frame 62, a steering drive device 64 mounted on the gantry frame 62 for driving the base 63 to rotate, a lifting drive assembly 521 located within the base 63, and a feeding drive device 52 further includes a pitch drive assembly connected to the output end of the lifting drive assembly 521, and a feeding rack 522 driven by a telescopic scissor frame for unloading materials from several forks 511. The loading device 51 also includes a shelf 512 connected to the output end of the pitch drive assembly and including several forks 511. The feeding rack 522 is mounted on the shelf 512, and the pitch drive assembly drives the shelf 512 to pitch to an inclined state. The conveying mechanism 5 is prior art and not the main inventive point of this application; its specific structure will not be elaborated here.

[0052] Working principle:

[0053] Control the flatbed truck to drive into the parking area of ​​the corresponding transport mechanism 5; specifically, the parking area is located between the two ground rails 61;

[0054] The feeding conveyor line 22 is controlled to feed several materials one by one into the clamping position 21. Specifically, the two feeding conveyors 221 are controlled to feed several materials alternately, and after receiving the materials through the raised feeding docking conveyor group 223, they are lowered and placed on the two feeding conveyor belt groups 222 for turning and conveying. The two feeding conveyor belt groups 222 alternately feed materials one by one into the clamping position 21.

[0055] The clamping mechanism 3 is controlled to reciprocate and move laterally to clamp the material on the clamping position 21 and release it one by one to several material-combining positions 111 on the material-combining platform 11 to form a combined material. At the same time, the discharge conveyor line 23 is controlled to output the tray on the clamping position 21 after the clamping mechanism 3 clamps the material, and the feed conveyor line 22 is controlled to input the next material to the clamping position 21 when the clamping mechanism 3 releases the material and resets.

[0056] After the material is formed on the material collection platform 11, the rotary drive device 12 is controlled to drive the material collection platform 11 to rotate laterally until the material discharge structure corresponds to the material loading device 51. Specifically, the rotary drive device 12 is controlled to drive the material collection platform 11 to rotate laterally by 90° so that the several material picking gaps 113 are coaxially aligned with the several forks 511. Then, the sliding frame 13 is controlled to drive the material collection platform 11 to slide until the several forks 511 are inserted into the several material picking gaps 113.

[0057] After the loading device 51 carries the material through the discharge structure, specifically, the lifting drive assembly 521 drives the loading device 51 to rise and lifts the material through several forks 511. The steering drive assembly 64 controls the loading device 51 to rotate to the corresponding direction. At the same time, the walking drive assembly 6 drives the conveying mechanism 5 to move laterally to the loading position. Then, the unloading drive assembly 52 drives the loading device 51 to unload the material to the loading position. Specifically, the steering drive assembly 64 controls the rotation angle of the loading device 51 to 180° and corresponds to the front of the flatbed truck, thereby transporting the material to the flatbed truck and filling a row of loading positions. Finally, the conveying mechanism 5 and the loading device 51 are reset to wait for the next round of transportation.

[0058] Repeat the above process until all materials are loaded onto the truck after filling several rows of loading positions.

[0060] When large-tonnage ton bags are filled with products that have a certain degree of fluidity, such as powders or crystalline granules, ordinary clamping mechanisms 3 are prone to causing the internal product to flow downwards and deform, making it difficult for the clamping mechanism 3 to complete its clamping work stably. Therefore, referring to... Figure 9 The difference between this embodiment and Embodiment 1 is that:

[0061] To improve the clamping stability of the clamping device 34, the clamping member 342 includes a clamping plate 3421 that extends forward and backward and connects to the sliding member 343. The opposing sides of the two clamping plates 3421 on the left and right are respectively provided with a plurality of clamping parts 3422. The plurality of clamping parts 3422 are distributed vertically and horizontally and form a plurality of outward expansion areas 3423 between them. The plurality of clamping parts 3422 extend forward and backward, and the opposing sides of the opposing clamping parts 3422 on the left and right are recessed to form a clamping groove 34221 that is adapted to the outer wall of the material. Thus, by adding a plurality of clamping parts 3422 and outward expansion areas 3423, when the two clamping members 342 of the plurality of clamping devices 34 move towards each other to clamp the material, the material is clamped by a plurality of clamping parts and the side deforms and expands outward to a plurality of outward expansion areas 3423. When the material is a ton bag, its side is clamped and squeezed by several clamping parts, and it can be locally expanded and deformed from top to bottom and embedded in several expansion areas 3423. This achieves upper and lower limit between the ton bag and the clamping parts 342, increases the contact area between the clamping parts and the side of the ton bag, reduces the risk of the ton bag deforming and slipping due to the internal product flowing downwards towards the center, and thus improves the clamping stability of the clamping device 34 on the ton bag.

[0062] To enhance the supporting force of the clamping parts, the protrusion height of the clamping parts 3422 gradually increases from top to bottom, and the cross-section of the outward expansion areas 3423 is trapezoidal, narrower at the top and wider at the bottom. By configuring the clamping parts 3422 in a stepped shape with gradually increasing protrusion height from top to bottom, and ensuring that the cross-section of the outward expansion areas 3423 is trapezoidal, when the material is a ton bag, after its side is clamped and squeezed by the clamping parts, the internal product tends to flow outward and downward into the outward expansion areas 3423. This not only promotes the localized outward expansion deformation of the ton bag's side from top to bottom, embedding it into the outward expansion areas 3423, but also prevents the ton bag's side from being damaged due to excessive pressure after clamping. Furthermore, it gradually increases the depth of the clamping parts embedded in the ton bag's side from top to bottom, thereby gradually increasing the supporting force of the clamping parts on the ton bag's side and further preventing the risk of the ton bag deforming and slipping.

[0063] To further improve the clamping stability of the clamping device 34, the lowest-level clamping device 34 also includes two bottom support members 345, which are respectively limited and rotatably disposed at the lower ends of the two clamping plates 3421 and extend towards each other. A pressure relief zone 346 is formed between the two bottom support members 345 and the two lowest clamping portions 3422, which expands after being limited and swayed downward by the two bottom support members 345. Specifically, the upper ends of the two bottom support members 345 are hinged to the lower ends of the corresponding clamping plates 3421, and the lower ends are inclined and folded towards each other. Several limiting members are fixedly arranged side by side at intervals on the outer side of the upper ends of the two bottom support members 345. 347, the upper ends of several limiting members 347 extend upward to the outside of the clamping plate 3421 to form limiting portions 3471, and the two bottom support members 345 rotate downward to be restricted when the several limiting portions 3471 abut against the outside of the clamping plate 3421; thus, by adding two bottom support members 345, when the two clamping members 342 of several clamping devices 34 move towards each other to clamp the material, the material is clamped by several clamping portions, and the side of the material deforms and expands outward to several expansion areas 3423, and the bottom deforms and supports the two bottom support members 345 and expands outward to release pressure to the two pressure relief areas 346. When the material is in a ton bag, after being clamped by several clamping parts, not only are the sides compressed and deformed from top to bottom in intervals, embedding into several expansion zones 3423 to achieve upper and lower limits between the ton bag and the clamping parts 342, but the bottom is also compressed and expanded outward to the pressure relief zone 346, supporting the two bottom supports 345 to rotate downward to the restricted position, thereby expanding the volume of the pressure relief zone 346 to relieve pressure on the lower part of the ton bag, avoiding the risk of rupture due to excessive pressure on the bottom of the ton bag. At the same time, through the expansion and pressure relief of the pressure relief zone 346, the tendency of the product inside the ton bag to flow outward and downward towards the expansion zone is increased, further enhancing the bottom of the ton bag. The outer expansion and the support of the bottom support 345 reduce the probability of the product inside the ton bag flowing downwards towards the center. This avoids the risk of the ton bag deforming and slipping due to the downward flow of the product inside. The ton bag deforms and fits into several outer expansion areas 3423 and pressure relief areas 346, further improving the clamping stability of the clamping device 34 on the ton bag. It also prevents the ton bag from becoming unstable on the material stacking platform 11 due to excessive concentration of the product inside. This improves the stability of the ton bag after it is clamped onto the material stacking platform 11, thereby improving the stability of the subsequent loading of the material stacking ton bags.
