Description

Technical Field

[0001] This utility model relates to ton bags, and more particularly to a high-strength ton bag structure that can automatically fill materials. Background Technology

[0002] Currently, ton bags are widely used due to their convenience and safety in cargo transportation, and sampling and analyzing the materials inside the bags is a common operational requirement. Although existing technologies exist, Chinese utility model patent CN223031818U solves the problem of waste leakage caused by traditional perforated sampling by setting a sealable reserved sampling component on the side fabric of the bag.

[0003] However, the existing technology still has structural defects. The patent uses a design mode in which the lifting strap and the bag body are connected separately. This means that when equipment such as forklifts lift the ton bag, the material load will be concentrated on the local area where the lifting strap and the side fabric are connected. This can easily cause stress concentration at the connection point. As a result, under excessive force or long-term use, the lifting strap may fall off the bag body, affecting the overall safety and transportation reliability of the ton bag. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a high-strength ton bag structure that can automatically fill materials, thereby improving structural strength and ton bag safety.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a high-strength ton bag structure that can automatically fill materials, including a bag body, the upper end of the bag body having an opening, and a groove being formed along the upper edge of the bag body towards the bottom of the bag body. The groove divides the upper edge of the bag body into a first connecting segment and a second connecting segment. The first connecting segment and the second connecting segment are fixedly connected to form a reinforcing segment, and a transport area is formed between the reinforcing segment and the groove.

[0006] To achieve the above technical solution, a groove is cut at a specific location along the upper edge of the bag, dividing the traditional upper edge of the bag into a first connecting section and a second connecting section. By fixing these two connecting sections together, a reinforced section is formed, and a unified transport zone is naturally enclosed between the reinforced section and the groove. During lifting operations, the load acts directly on the integral structure formed by the extension and reinforcement of the bag's own material through the transport zone, evenly distributing the weight of the material across the upper load-bearing structure of the bag, rather than concentrating it at the traditional, independently sewn lifting strap connection points. This fundamentally solves the technical problem of stress concentration at the connection between the lifting straps and the bag body, eliminates the safety hazard of lifting straps detaching due to excessive localized stress, and significantly improves the overall structural strength, transport reliability, and operational safety of the ton bag.

[0007] As a preferred embodiment of the present invention, it further includes a protective layer, which covers the reinforcing section.

[0008] To achieve the above technical solution, a protective layer is applied to the outside of the reinforced section, further protecting and reinforcing the core load-bearing area. During hoisting, this protective layer effectively resists friction and wear from hoisting equipment (such as forklift forks), delaying material aging in the reinforced section. This not only enhances the durability and tear resistance of the reinforced section but also provides double protection for the fixed connection between the first and second connecting sections, thereby further extending the overall service life of the ton bag in harsh operating environments and improving its long-term safety and reliability.

[0009] As a preferred embodiment of this utility model, a feeding bag is fixedly connected to the inner wall of the bag body. The feeding bag is vertically continuous and communicates with the interior of the bag body, and the upper end of the feeding bag extends out from the transport area.

[0010] To achieve the above technical solution, a vertically continuous feed bag is fixedly connected to the inner wall of the bag body, with its upper end extending from the conveying area, thus enhancing the functionality of the bag body. During material filling, the material enters the bag body through this feed bag, effectively providing a wear-resistant protective lining to the inner wall of the bag, mitigating the impact and wear on the main structure of the bag body as the material falls. Simultaneously, because it is vertically continuous and connected to the bag body, it guides the material flow, improving filling efficiency, and ensures that the material is ultimately evenly filled throughout the entire bag body.

[0011] In a preferred embodiment of this utility model, the feed bag is fixed to the inner wall of the bag body by a reinforcing ring, and the groove is located on the side of the reinforcing ring facing the reinforcing section.

[0012] The above technical solution utilizes a reinforcing ring to fix the feed bag to the inner wall of the bag body, which serves a dual crucial function. First, it provides a stable and secure connection base for the feed bag. Second, the reinforcing ring is positioned below the cut groove. During the hoisting of the ton bag, the enormous load causes shear stress to concentrate at the bottom of the cut groove, a potential structural weak point. The presence of the reinforcing ring acts as a lateral stress interruptor and reinforcement, effectively bearing and dispersing the concentrated stress from the end of the cut groove, fundamentally inhibiting the generation and propagation of cracks, and eliminating the significant safety hazard of longitudinal tearing of the bag body.

[0013] In a preferred embodiment of this utility model, the reinforcing ring includes an inner ring portion and an outer ring portion. The inner ring portion is disposed inside the feed bag, and the outer ring portion is disposed outside the bag body. The inner ring portion, the outer ring portion, the feed bag, and the bag body are fixedly connected.

[0014] To achieve the above technical solution, the reinforcing ring is designed as a double-ring structure with an inner and outer ring. The inner ring is placed inside the feed bag, and the outer ring is placed outside the bag body. The fabric of the feed bag and the bag body are clamped between the inner and outer rings for integrated fixation. This clamp-type mechanical fixation method transfers the load acting on the feed bag to the main structure of the bag body through the large-area clamping force of the inner and outer rings, rather than through a single stitch or adhesive layer. This structure fundamentally improves the connection strength and anti-peeling and anti-tear properties between the feed bag and the bag body, effectively eliminating the risk of failure due to stress concentration in the connection area. At the same time, this composite ring structure significantly enhances the overall rigidity of the bag opening, ensuring the geometric stability and long-term durability of this critical connection area during dynamic processes such as filling and hoisting.

[0015] As a preferred embodiment of this utility model, a transparent storage bag is connected to the outer wall of the bag body.

[0016] To achieve the above technical solution, a transparent storage bag is attached to the outer wall of the bulk bag, providing a standardized information carrying and display unit. During transportation and warehousing, important documents such as shipping documents, product information cards, and inspection certificates can be placed inside this transparent storage bag. Operators can intuitively and conveniently identify the material information and related operational instructions inside the bag without opening the packaging or searching separately, greatly improving the efficiency and accuracy of logistics management and reducing the risk of operational errors caused by information gaps.

[0017] As a preferred embodiment of this utility model, the transparent storage bag has a self-sealing strip connected to its opening for sealing the opening.

[0018] To achieve the above technical solution, a self-sealing strip is added to the opening of the transparent storage bag, effectively protecting the stored documents. By pressing the self-sealing strip, the opening can be quickly and easily closed, forming a relatively sealed space. This structure effectively prevents rainwater, dust, and other external environmental factors from damaging the internal paper documents, ensuring the clarity and integrity of the documents throughout the entire transportation and storage cycle, thereby guaranteeing the reliable transmission of critical information.

[0019] As a preferred embodiment of this utility model, the transparent storage bag is fixed to the bag body on the side adjacent to the self-sealing strip.

[0020] The above technical solution enables the transparent storage bag to be flipped along one side, allowing operators to view the documents inside the transparent storage bag from multiple angles.

[0021] As a preferred embodiment of this utility model, a reinforcing plate is provided inside the bag body. The length direction of the reinforcing plate is parallel to the height direction of the bag body, and the two sides of the reinforcing plate are fixedly connected to two adjacent inner walls of the bag body.

[0022] To achieve the above technical solution, the material is placed inside the bag, and the reinforcing sheet can improve the structural strength of the inner wall of the bag and reduce the deformation of the inner wall of the bag.

[0023] As a preferred embodiment of this utility model, the reinforcing sheet has grooves, and a plurality of grooves are arranged along the length direction of the reinforcing sheet.

[0024] The above technical solution is implemented to facilitate the material to pass through the reinforcing sheet from the trough, thereby improving the discharge efficiency. Attached Figure Description

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0028] A high-strength ton bag structure capable of automatically filling materials includes a bag body 1, which has a square structure when unfolded. An opening is located at the top of the bag body 1.

[0029] Reinforcing pieces 14 are provided inside the bag body 1. There are four reinforcing pieces 14, located at the four corners of the bag body 1. The length direction of the reinforcing pieces 14 is parallel to the height direction of the bag body 1, and the two sides of the reinforcing pieces 14 are fixedly connected to the two adjacent inner walls of the bag body 1. The reinforcing pieces 14 are fixed to the inner walls of the bag body 1 by sewing. The material of the reinforcing pieces 14 is the same as that of the bag body 1.

[0030] The reinforcing plate 14 has grooves 15, and multiple grooves 15 are arranged along the length of the reinforcing plate 14. The cross-section of the grooves 15 is a rounded square.

[0031] A groove 2 is provided along the upper edge of the bag body 1 towards the bottom. The groove 2 has two sections and is arranged along the length of the bag body 1. The groove 2 divides the upper edge of the bag body 1 into a first connecting section 3 and a second connecting section 4. The ends of the first connecting section 3 and the second connecting section 4 are unfolded, then glued together and fixed by sewing. The sewn part is then folded to form a reinforcing section 13. A transport area 7 is formed between the reinforcing section 13 and the groove 2.

[0032] The protective layer 5 is sheet-like. After the protective layer 5 is wrapped around the reinforcing section 13, the two ends of the protective layer 5 are sewn together.

[0033] A feed bag 6 is fixedly connected to the inner wall of the bag body 1. The feed bag 6 runs vertically through the bag body 1 and communicates with the interior of the bag body 1. The upper end of the feed bag 6 extends out from the conveying area 7.

[0034] The feed bag 6 is fixed to the inner wall of the bag body 1 by a reinforcing ring 8, and the groove 2 is located on the side of the reinforcing ring 8 facing the reinforcing section 13. The reinforcing ring 8 includes an inner ring portion 9 and an outer ring portion 10. The lower end of the feed bag 6 is fixed to the inner wall of the bag body 1, and then the inner ring portion 9 is placed on the inner wall of the feed bag 6, so that the inner ring portion 9 is close to the lower opening of the feed bag 6. The outer ring portion 10 is placed on the outer wall of the bag body 1, and the position of the outer ring portion 10 corresponds to the position of the inner ring portion 9. Finally, the outer ring portion 10 and the inner ring portion 9 are fixed by sewing, thereby fixing the reinforcing ring 8, the feed bag 6, and the bag body 1 into a whole.

[0035] A transparent storage bag 11 is provided on the outer wall of the bag body 1. One long side of the transparent storage bag 11 is fixed to the outer wall of the bag body 1 by sewing, and the length direction of the transparent storage bag 11 is parallel to the length direction of the bag body 1.

[0036] A self-sealing strip 12 for sealing the opening is fixedly connected to the opening of the transparent storage bag 11.

[0037] The transparent storage bag 11 is a transparent self-sealing bag.

[0038] Both the feed bag 6 and the protective layer 5 are made of PE material.

[0039] During filling, the feed bag 6 is pulled out from the bag body 1 and opened and clamped by the filling machine. Then, the material is injected into the bag body through the feed bag 6 by the filling machine, thereby realizing the function of automatic material filling. After filling is completed, the feed bag 6 is sealed by heat fusion.

[0040] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
