[0027] EMBODIMENT

[0028] The ton bag with good bearing capacity comprises a ton bag body 1, two annular reinforcing belts 2, and a protective layer 5.

[0029] In this embodiment, as shown in Figure 1 and Figure 2 two annular reinforcing belts 2 are distributed in a cross shape on the outer bottom wall of the ton bag body 1. This layout not only enhances the structural strength of the bottom of the ton bag, but also effectively disperses the weight borne by the bottom, preventing damage caused by excessive local pressure. The two ends of the reinforcing belt 2 are bent upward and fixedly connected to the outer side wall of the ton bag body 1, which not only increases the stability of the connection point, but also makes the structure of the entire ton bag more stable.

[0030] The reinforcing belt 2 extends upward to the outside of the ton bag and forms a lifting lug 3, which not only facilitates hoisting and transportation, but also further enhances the bearing capacity and stability of the ton bag. The lifting lug 3 serves as a stress point during hoisting, and it is integrally formed with the reinforcing belt 2. Its strength is supported by the reinforcing belt 2, making the lifting lug 3 less likely to break, thereby ensuring the safety of the ton bag during hoisting and transportation. The protective layer 5 located on the bottom surface of the ton bag body 1 provides additional protection for the bottom of the ton bag. The reinforcing belt 2 is located between the protective layer 5 and the outer bottom wall of the ton bag body 1. This layout not only protects the reinforcing belt 2 from direct wear and corrosion, but also further improves the durability and bearing capacity of the ton bag through the cushioning effect of the protective layer 5. This ton bag with good bearing capacity, through the ingenious combination of the reinforcing belt 2, the lifting lug 3, and the protective layer 5, significantly improves the structural strength, bearing capacity, and durability. The simple structure not only improves the safety of the ton bag, but also prolongs its service life and reduces the cost of use.

[0031] Further, the cross section of the reinforcing belt 2 is rectangular, and multiple reinforcing ribs 201 are embedded in the reinforcing belt 2.

[0032] Specifically, the rectangular cross-section can provide more stable structural support. Compared with circular or other shapes, the rectangle is less likely to deform when subjected to pressure. The rectangular cross-section of the reinforcing band 2 is simpler and more convenient to process and manufacture, reducing production costs. The rectangular cross-section can better distribute and withstand the weight from the ton bag body 1, improving the overall load-bearing performance. Embedding multiple reinforcing ribs 201 in the reinforcing band 2 can further enhance its load-bearing capacity and stability. The reinforcing ribs 201 can increase the overall strength of the reinforcing band 2, enabling it to withstand greater pressure and tension. By embedding multiple reinforcing ribs 201, pressure can be dispersed to a wider area, avoiding damage caused by excessive local pressure. The reinforcing ribs 201 can also increase the toughness of the reinforcing band 2, enabling it to better absorb and disperse energy when subjected to external force impact, thereby improving the durability of the ton bag. The combination of the reinforcing band 2 and the reinforcing ribs 201 enables the ton bag to withstand greater weight, suitable for transporting a wider variety of goods. The design of the rectangular cross-section and the reinforcing ribs 201 makes the ton bag more stable during transportation and storage, less likely to tip over or break. By improving the load-bearing capacity and stability of the ton bag, its service life can be extended, reducing replacement costs.

[0033] Further, the multiple reinforcing ribs 201 are spaced apart along the length direction of the cross-section of the reinforcing band 2, and the multiple reinforcing ribs 201 are annularly distributed inside the reinforcing band 2.

[0034] Specifically, as shown in Figure 3 the multiple reinforcing ribs 201 are spaced apart along the length direction of the cross-section of the reinforcing band 2. This distribution ensures that the pressure is more evenly distributed to each reinforcing rib 201 when the reinforcing band 2 is subjected to pressure, avoiding excessive local pressure. At the same time, the spaced distribution helps to improve the overall flexibility and toughness of the reinforcing band 2. The reinforcing ribs 201 are annularly distributed inside the reinforcing band 2 to adapt to the annular reinforcing band 2. This design can enhance the circumferential strength of the reinforcing band 2, making it more stable when subjected to tension or torsion. The annularly distributed reinforcing ribs 201 can also effectively prevent cracks or fractures in the reinforcing band 2 due to fatigue during long-term use.

[0035] Further, the multiple reinforcing ribs 201 are staggered to form a grid-like distribution inside the reinforcing band 2.

[0036] Specifically, as shown in Figure 4As shown, the grid-distributed reinforcing ribs 201 can more effectively disperse stress throughout the reinforcing belt 2, avoiding the problem of local stress concentration. This design allows the reinforcing belt 2 to maintain good stability and durability when subjected to various complex stresses. The overall strength of the reinforcing belt 2 is significantly improved through the interlaced reinforcing ribs 201. This design not only improves the tensile and compressive performance of the reinforcing belt 2, but also enhances its shear and torsional resistance, making the ton bag more secure and reliable during transportation and storage. The grid-distributed reinforcing ribs 201 allow the reinforcing belt 2 to withstand greater weight while maintaining structural stability and safety. This design is particularly suitable for scenarios that require the ability to withstand heavy weight and complex stresses. By optimizing the distribution of reinforcing ribs 201, the fatigue resistance of the reinforcing belt 2 is improved. Even after long-term use and multiple cyclic loads, the reinforcing belt 2 can maintain good performance.

[0037] Further, the reinforcing rib 201 is a steel wire rope or a nylon rope.

[0038] Further, the inside of the lifting lug 3 is provided with a wear-resistant layer 4 made of polytetrafluoroethylene.

[0039] Specifically, the lifting lug 3 is the stress point during the hoisting of the ton bag and is often subjected to friction and wear. The application of the PTFE wear-resistant layer 4 can significantly improve the wear resistance of the lifting lug 3 and prolong its service life. PTFE also has good corrosion resistance. This feature allows the lifting lug 3 to maintain its performance stability when in contact with corrosive substances, further extending the service life of the lifting lug 3. The presence of the wear-resistant layer 4 reduces the wear and deformation of the lifting lug 3 during hoisting, thereby improving the safety of the ton bag during transportation and storage.

[0040] Further, the protective layer 5 is curved upwards around the periphery to form a groove, and the inner wall of the groove is provided with a waterproof layer 6.

[0041] Specifically, as shown in FIG. 6, the reinforcing belt 2 is provided with a protective layer 5 made of polytetrafluoroethylene (PTFE) on the outer surface of the reinforcing belt 2. Figure 2As shown, the groove formed by the upward bending of the protective layer 5 around the perimeter can be considered as an edge reinforcement design, which can enhance the structural stability of the protective layer 5 and prevent it from deforming or breaking under stress. The groove itself can act as an additional barrier to prevent moisture from seeping in from the bottom edge of the ton bag, especially in humid or rainy environments, where this design is particularly important. The waterproof layer 6 set on the inner wall of the groove can significantly improve the waterproof performance of the ton bag bottom. The waterproof layer 6 can prevent moisture from seeping into the ton bag through tiny gaps or holes, protecting the goods inside the bag from moisture. The waterproof layer 6 is usually made of high-molecular waterproof materials, which have excellent wear resistance and corrosion resistance. Therefore, the waterproof layer 6 not only prevents moisture from penetrating, but also enhances the durability of the ton bag bottom, prolonging its service life. For goods that need to be kept dry, such as chemicals, food, etc., the design of the waterproof layer 6 is crucial. It can effectively prevent the goods from deteriorating or being damaged due to moisture, ensuring the safety of the goods during transportation and storage.

[0042] Further, the ton bag body 1 is fixed with a plurality of pull bars 7, and the pull bars 7 are fixedly connected with the reinforcing belt 2, and the pull bars 7 are annular.

[0043] Further, the pull bars 7 are provided in multiple, and the multiple pull bars 7 are distributed along the height direction of the ton bag body 1.

[0044] Specifically, as shown in the figure, Figure 1 The annular pull bar 7 can significantly enhance the structural stability of the ton bag body 1, and the pull bar 7 can support the ton bag like a skeleton, so that the ton bag can maintain stable shape and is not easy to break when facing external pressure or tension. The pull bar 7 can disperse the stress borne by the ton bag body 1 to a wider area, avoiding damage caused by excessive local stress, and this stress dispersion effect is particularly obvious when the ton bag is loaded with heavy objects. Through the fixed connection with the reinforcing belt 2, the pull bar 7 can further enhance the load-bearing capacity of the ton bag, and this design makes the ton bag stable when loaded with heavy objects and not easy to overturn or break. The multiple pull bars 7 are distributed along the height direction of the ton bag body 1, which can further optimize the distribution of stress, and this design makes the ton bag maintain good stability when bearing vertical and horizontal forces. By increasing the number of pull bars 7 and distributing them along the height direction, the overall strength of the ton bag can be significantly improved, and this design makes the ton bag better resist fatigue and wear during long-term use.

[0045] Further, the reinforcing belt 2 and the ton bag body 1 are fixedly connected by sewing or rivets.

[0046] Specifically, the sewing connection is achieved by sewing the reinforcing belt 2 with the edge of the ton bag body 1. This connection method usually uses high-strength sewing thread and professional sewing equipment to ensure the firmness and durability of the connection. The sewing connection has the advantages of high flexibility, strong adaptability, relatively low cost, etc. It can be customized according to the shape and size of the ton bag, and the sewing process is relatively simple and easy to realize automated production. The sewing connection is suitable for occasions where the strength of the ton bag is not particularly high or the reinforcing belt 2 needs to be frequently replaced. At the same time, it is also suitable for some scenarios with certain cost requirements.

[0047] The rivet connection is achieved by driving a rivet between the reinforcing belt 2 and the ton bag body 1. This connection method usually uses high-strength metal rivets to ensure the firmness and stability of the connection. The rivet connection has the advantages of high connection strength, strong tear resistance, long service life, etc. It can maintain the stability of the connection in extreme environments and ensure that the ton bag does not easily break when bearing heavy objects. The rivet connection is suitable for occasions where the strength of the ton bag is particularly high or needs to bear heavy objects and complex stresses for a long time. At the same time, it is also suitable for some scenarios with particularly high safety requirements, such as chemical transportation, heavy equipment hoisting, etc.

[0048] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. According to the technical essence of the present application, any simple modification, equivalent replacement, improvement, etc. of the above embodiment within the spirit and principles of the present application still falls within the protection scope of the technical scheme of the present application.
