Description

Technical Field

[0001] This utility model relates to the field of industrial material transportation technology, and in particular to a ton bag that facilitates the tipping of materials. Background Technology

[0002] In modern industrial production and logistics, ton bags, as commonly used large container containers, are widely used for the storage and transfer of various powdery and granular materials. However, traditional ton bags have many drawbacks in the unloading process, such as the need for manual assistance in tipping during unloading, which is inefficient and labor-intensive; the bottom structure has limited load-bearing capacity, making it prone to deformation when loaded with heavy objects, leading to material leakage; and the lack of effective unloading auxiliary devices makes it difficult to achieve fast and clean unloading.

[0003] A search revealed Chinese Patent Publication No. CN219949219U, which discloses a ton bag for easy tipping of materials. The bag includes a bag body and several lifting lugs. The bag body has an opening, and the lifting lugs are respectively located on the bottom of the bag body and around the opening. All the lifting lugs on the same end are connected by a connecting strap. One end of the connecting strap is connected to a tipping strap, and the other end of the tipping strap is connected to the side of the bag body. This ton bag facilitates easy tipping of materials and helps maintain a stable center of gravity during unloading.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following deficiencies: the connection between the tipping belt and the side of the bag relies on flexible traction, which is insufficient for supporting the tipping torque of high-density materials. Furthermore, the lack of a rigid support structure to effectively constrain the bottom shape of the bag may lead to excessive deformation of the bag during unloading, affecting the smoothness of unloading. At the same time, its center of gravity balance control mainly relies on the layout of the lifting lugs, and the support stability still needs to be improved when operating on complex terrain or non-horizontal ground. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides a ton bag that facilitates the tipping of materials.

[0006] The technical solution adopted by this utility model is as follows: a ton bag for easy material tipping, comprising a main bag body and a lifting belt, wherein a rigid support frame is sewn to the bottom of the main bag body; a movable unloading base plate is provided in the central area of ​​the rigid support frame, the edge of which is connected to the main bag body through a flexible connector; double lever lifting arms are symmetrically hinged on both sides of the rigid support frame, with the short arm end of the lifting arm facing downwards from the movable unloading base plate; foldable support columns are provided at the four corners of the rigid support frame; the upper end of the linkage cable assembly is fixed to the root of the lifting belt, and the lower end is connected to the long arm end of the double lever lifting arm; a guide limiting ring is provided on the side of the main bag body, through which the linkage cable assembly passes.

[0007] Through the above scheme, the rigid support frame provides stable bottom support for the ton bag, the movable unloading base plate with flexible connection facilitates material tipping, the double lever lifting arm and linkage cable assembly provide mechanical assistance during unloading, the foldable support column ensures stable placement, and the guide limit ring ensures accurate cable movement trajectory. The overall structure improves the convenience and stability of unloading the ton bag.

[0008] Preferably, the movable unloading base plate is made of polyurethane reinforced fabric composite material, and the surface is provided with wavy anti-slip embossed texture.

[0009] Through the above solution, polyurethane reinforced fabric composite material has both strength and flexibility, adapting to the deformation requirements during unloading. The wavy anti-slip ridges can increase the friction between the material and the base plate, preventing the material from sliding before unloading. At the same time, it can be easily overturned with the help of the base plate during unloading, balancing the stability and unloading convenience during use.

[0010] Preferably, the fulcrum position of the double-lever lifting arm satisfies the ratio of the short arm end length to the long arm end length being in the range of 1:3 to 1:5.

[0011] Through the above scheme, this ratio range enables the double-lever lifting arms to form a reasonable lever arm relationship, and uses the lever principle to achieve labor-saving lifting. When the short arm end lifts the movable unloading base plate, the tension transmitted by the long arm end through the linkage cable assembly is reduced. The operator only needs to apply a small force to complete the lifting action of the unloading base plate, which improves the labor-saving and efficiency of the operation.

[0012] Preferably, the foldable support column is connected to the rigid support frame via a rotating hinge, and when unfolded, it forms an angle of 75°-85° with the ground.

[0013] The above solution enables the rotating hinge to flexibly fold and unfold the support column. The unfolding angle of 75°-85° allows the support column to form a stable support state that is close to vertical with the ground, enhancing the anti-tipping ability of the ton bag when it is placed. At the same time, it does not take up too much space after folding, making it convenient for the storage and transportation of the ton bag, thus taking into account both the stability during use and the convenience of storage.

[0014] Preferably, the linkage cable assembly includes a high-strength polyester braided strip and a butterfly buckle. The butterfly buckle is movably sleeved on one side of the high-strength polyester braided strip, and the contact surface between the butterfly buckle and the high-strength polyester braided strip is provided with anti-slip texture.

[0015] Through the above solution, the high-strength polyester braided belt ensures the load-bearing capacity and durability of the cable assembly, the butterfly buckle can flexibly adjust the connection position to adapt to the needs of different unloading scenarios, and the anti-slip texture increases the friction between the buckle and the braided belt to prevent the buckle from sliding on the cable, ensuring the reliability and stability of the linkage cable assembly when transmitting tension, and ensuring the smooth operation of the unloading action.

[0016] Preferably, the guide limiting ring has slots on both the left and right sides for engaging with the hook to lift the long arm end of the double lever lifting arm.

[0017] Through the above scheme, the guide limit ring provides a precise point of action for the hook. During the hoisting process, the hook can directly lift the long arm end of the double lever lifting arm through the slot. With the guiding effect of the guide limit ring, the tension transmission path is more stable, avoiding the cable assembly from deviating and ensuring that the double lever lifting arm rotates in the predetermined direction, thus improving the controllability and safety of the unloading operation.

[0018] Preferably, the rigid support frame has intersecting reinforcing ribs embedded inside, forming a grid-shaped load-bearing structure.

[0019] Through the above scheme, the grid-shaped load-bearing structure formed by the cross-reinforcing ribs evenly distributes the external load to various parts of the rigid support frame, effectively enhancing the overall rigidity and compressive strength of the frame. It can withstand the weight of the ton bag when loading materials and the mechanical force during the unloading process, extending the service life of the ton bag and ensuring the structural safety during use. Beneficial effects

[0020] The beneficial effects of this utility model are as follows: By setting up a rigid support frame, a movable unloading base plate, a double-lever lifting arm, and a linkage cable assembly, the linkage cable assembly, through the cooperation between the linkage cable assembly and the double-lever lifting arm, allows the linkage cable assembly to pull the long arm end of the double-lever lifting arm using the lifting force of the hoisting belt. This leverages the lever principle to lift the short arm end upwards, raising the movable unloading base plate. The edge of the movable unloading base plate is connected to the main bag body via flexible connectors. After being lifted, it can change the support state of the material, thus achieving the effect of conveniently tipping and unloading the material inside the ton bag through mechanical linkage, effectively improving the efficiency and convenience of material unloading. By incorporating components such as foldable support legs, guide rings, and cross-reinforcing ribs, and through the rotary hinge connection between the foldable support legs and the rigid support frame, as well as the guiding and limiting effect of the guide rings on the linkage cable assembly, the foldable support legs can form a stable angle with the ground when unfolded, providing solid support for the ton bag. Simultaneously, the guide rings ensure the accurate movement trajectory of the linkage cable assembly. The cross-reinforcing ribs inside the rigid support frame form a grid-like load-bearing structure, enhancing overall rigidity. The movable unloading base plate is made of polyurethane reinforced fabric composite material with anti-slip textures, improving durability and material load-bearing stability. Thus, this device achieves stable support, precise linkage, and safe and efficient material tipping and loading. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1 to 5 As shown, a ton bag for easy tipping includes a main bag body 1 and lifting straps. A rigid support frame 2 is sewn to the bottom of the main bag body 1. The rigid support frame 2 has intersecting reinforcing ribs embedded inside, forming a grid-shaped load-bearing structure. The rigid support frame 2, combined with the intersecting reinforcing ribs, can evenly distribute the weight of the material, enhance the bottom load-bearing capacity, prevent the ton bag from deforming or breaking when loaded with heavy objects, and improve the overall structural stability.

[0029] The rigid support frame 2 has a movable unloading base plate 3 in its central area. The movable unloading base plate 3 is made of polyurethane reinforced fabric composite material with a wavy anti-slip texture on its surface. The edge of the base plate is connected to the main bag body 1 through flexible connectors. Double-lever lifting arms 4 are symmetrically hinged on both sides of the rigid support frame 2. The fulcrum position of the double-lever lifting arms 4 satisfies the ratio of the short arm length to the long arm length ranging from 1:3 to 1:5. The short arm end of the lifting arm faces downwards from the movable unloading base plate 3. The anti-slip texture of the movable unloading base plate 3 effectively prevents material slippage, and the flexible connectors allow for flexible tilting. Combined with the labor-saving structure of the double-lever lifting arms 4, the base plate can be easily lifted during hoisting, enabling rapid material dumping and improving unloading efficiency.

[0030] The rigid support frame 2 has foldable support legs 5 at its four corners; the upper end of the linkage cable assembly 6 is fixed to the root of the lifting sling, and the lower end is connected to the long arm end of the double-lever lifting arm 4; the main bag body 1 has a guide limiting ring 7 on its side, through which the linkage cable assembly 6 passes. The foldable support legs 5 are connected to the rigid support frame 2 via a rotating hinge, and when unfolded, they form an angle of 75°-85° with the ground. After unfolding, the foldable support legs 5 can stably support the ton bag, keeping it balanced when standing. When folded, they do not occupy extra space, facilitating transportation and storage. The linkage cable assembly 6 is guided by the guide limiting ring 7 to ensure that the cable is evenly stressed, improving the stability and reliability of the lifting arm linkage.

[0031] The linkage cable assembly 6 includes a high-strength polyester braided strap and a butterfly buckle. The butterfly buckle is movably fitted onto one side of the high-strength polyester braided strap, and the contact surface between the butterfly buckle and the high-strength polyester braided strap has anti-slip texture. The guide limiting ring 7 has slots on both sides for engaging with the hook to lift the longer end of the double-lever lifting arm 4. The high-strength polyester braided strap ensures the strength and durability of the linkage cable assembly 6, the butterfly buckle allows for flexible adjustment of the cable length, the anti-slip texture prevents the buckle from slipping, and the slots, in conjunction with the hook, precisely transmit the lifting force, ensuring coordinated movement of the double-lever lifting arm 4 and achieving a smooth and controllable material tipping process.

[0032] In a chemical raw material storage workshop, forklifts use lifting straps to transport ton bags containing polyethylene granules to the unloading station. The operator first unfolds the foldable support legs 5 from the bottom of the rigid support frame 2 via rotating hinges, creating an 80° angle between the foldable support legs 5 and the ground. The ton bags are then stably placed on the steel unloading platform using the four corner foldable support legs 5. At this point, the grid-shaped intersecting reinforcing ribs inside the rigid support frame 2 bear the weight of the material, ensuring that the bottom structure does not deform.

[0033] When the crane hook engages with the base of the lifting sling and lifts it upwards, the high-strength polyester braided strap of the linkage cable assembly 6 passes through the guide limiting ring 7 on the side of the main bag body 1, and the long arm end of the double-lever lifting arm 4 connected to its lower end is simultaneously pulled up. Since the fulcrum position of the double-lever lifting arm 4 satisfies the ratio of the short arm end to the long arm end length of 1:4, according to the lever principle, the short arm end pushes upwards against the movable unloading base plate 3 with four times the force of the long arm end. The flexible connectors at the edge of the movable unloading base plate 3 are stretched, causing the base plate to flip upwards around the central area. The wavy anti-slip texture on the surface ensures that the polyethylene granules slide smoothly down to the feed inlet of the screw conveyor below as the base plate tilts. During unloading, the slots on both sides of the guide limiting ring 7 cooperate with the hook to prevent the linkage cable assembly 6 from shifting laterally, ensuring the synchronous movement of the double-lever lifting arm 4.

[0034] The implementation principle of a ton bag for easy material tipping in this application embodiment is as follows:

[0035] First, when the ton bag is placed on the ground, the foldable support column 5 unfolds through the rotating hinge, forming a stable angle of 75°-85° with the ground. Together with the grid-shaped cross reinforcing ribs inside the rigid support frame 2, it forms a stable bottom support structure. At this time, the movable unloading bottom plate 3 is laid horizontally in the center of the rigid support frame 2, and its edge is connected to the main bag body 1 through flexible connectors, so as to evenly bear the weight of the material inside the bag and ensure that the material is stably stored when the ton bag is upright.

[0036] Secondly, when the crane hook catches the lifting sling and lifts it upward, the linkage cable assembly 6 is simultaneously subjected to force along with the lifting sling. Its upper end is fixed to the root of the lifting sling, which allows the tension to be directly transmitted to the cable. The guide limit ring 7 forms a lateral constraint on the cable, ensuring that the tension is transmitted vertically to the long arm end of the double lever lifting arm 4. According to the lever principle, when the long arm end is pulled downward, the short arm end tilts upward, forming a lifting force on the bottom of the movable unloading base plate 3.

[0037] Next, after the short arm end of the double-lever lifting arm 4 lifts the movable unloading base plate 3, the base plate tilts around the edge where the flexible connector is located. Because the flexible connector allows for a certain angle of rotation and deformation, the base plate and the bottom of the main bag body 1 form an unloading tilt angle. The material inside the bag slides in the tilting direction under the action of gravity and is discharged through the opening of the main bag body 1 or the unloading port. The wave-shaped anti-slip ridges on the surface of the base plate prevent the material from slipping locally in the initial tilting stage, ensuring uniform unloading. The polyurethane reinforced fabric composite material takes into account both the mechanical requirements of rigid support and flexible rotation.

[0038] Next, after the material is unloaded and the lifting belt is loosened, the double-lever lifting arm 4 loses the tension of the cable. Under the action of its own weight and the residual weight of the material, the long arm end falls back to the initial hinge position, and the short arm end descends simultaneously. The movable unloading base plate 3 returns to a horizontal state by relying on the rebound force of the flexible connector and its own weight. At this time, the foldable support column 5 can be folded through the rotating hinge to fit the rigid support frame 2, which is convenient for the storage or transfer of ton bags and reduces the storage space occupied.

[0039] Finally, the entire working process is achieved through the mechanical linkage of "lifting trigger - lever lifting - base plate flipping - gravity unloading - reset and storage": the lifting belt and linkage cable assembly 6 convert the lifting force into the flipping torque of the lifting arm, the guide limit ring 7 ensures the accurate transmission direction of the force, the rigid support frame 2 and the foldable support column 5 provide stable mechanical fulcrum, and the movable unloading base plate 3 achieves angle change through flexible connection and lever lifting. Finally, the material is flipped over by gravity. The components form a closed-loop working process through structural cooperation, avoiding manual intervention and improving unloading efficiency and safety.
