Abstract
Description
Technical Field
[0001] This utility model relates to the field of woven bag technology, specifically a high-strength wear-resistant woven bag. Background Technology
[0002] Woven bags are a common packaging material, typically made by weaving flat yarns from plastic granules such as polypropylene (PP) or polyethylene (PE). This type of bag has good strength and durability, can withstand a certain weight, and is waterproof and moisture-proof, making it suitable for transporting and storing various items, such as grains, chemical raw materials, and building materials. To ensure that woven bags can better store and transport goods, higher quality raw materials and more refined production processes are usually used in their manufacture to ensure that they can withstand heavier loads and maintain good performance in harsh environments.
[0003] For example, patent CN215324322U discloses a high-strength, wear-resistant, color-printed woven bag, including a woven tote bag. A through-slot is formed at the top edge of the woven tote bag, and a lifting mechanism is installed through the inside of the through-slot. The lifting mechanism includes a connecting strap that passes through the through-slot of the woven tote bag. A secondary carrying strap is fixedly connected to the left side of the connecting strap, and a main carrying strap is fixedly connected to the right side of the connecting strap. By setting up the lifting mechanism, the closed frame passes through the through-slot of the woven tote bag, thereby reinforcing the through-slot. Simultaneously, by fitting the main carrying strap and the secondary carrying strap together, they are integrated into one unit. When lifting the woven tote bag, this effectively increases the pulling force of the main and secondary carrying straps, preventing them from breaking due to excessive force during the lifting process.
[0004] However, the woven bags using the above technology still have the following problems:
[0005] Although the design of the main and auxiliary carrying straps and the closed frame can improve the tensile strength of the main and auxiliary carrying straps, when heavy objects are placed in the woven bag, even if the carrying straps can withstand the weight without breaking, the connection between the carrying straps and the woven bag may still break due to the small indirect area. At the same time, the bottom of the woven bag is subjected to greater force and may be stretched and deformed, which may lead to the bottom of the woven bag breaking and causing the contents to fall out and be damaged. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a high-strength, wear-resistant woven bag, such as by improving the connection strength between the lifting strap and the woven bag to prevent the lifting strap from breaking when storing heavy objects, and by reinforcing the bottom of the woven bag to prevent deformation or breakage under stress.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-strength wear-resistant woven bag, comprising a woven bag body, two through holes are provided on both sides of the open end of the woven bag body, and a reinforcing ring is fixedly connected to each of the four through holes. A handle is provided between two reinforcing rings on the same side. A first reinforcing component and a second reinforcing component are connected to the inner wall of the woven bag body. The first reinforcing component is connected to an adjacent reinforcing ring and to the second reinforcing component. A third reinforcing component is connected to the bottom inner wall of the woven bag body. The third reinforcing component is connected to the first and second reinforcing components.
[0008] Furthermore, the first reinforcing component includes several annular reinforcing ribs, which are equidistantly distributed from bottom to top from the bottom of the woven bag body, and are all fixedly connected to the inner sidewall of the woven bag body. The several annular reinforcing ribs are all connected to the second reinforcing component, and the bottommost annular reinforcing rib is connected to the third reinforcing component.
[0009] Furthermore, the second reinforcing component includes four reinforcing ribs and two side ribs. The four reinforcing ribs and the two side ribs are all located inside the woven bag body. One end of each of the four reinforcing ribs is fixedly connected to the bottom of the four reinforcing rings, and the other end extends downward and is fixedly connected to several annular reinforcing ribs and the inner wall of the woven bag body. The two side ribs are fixedly connected to the inner walls of the woven bag body on both sides away from the four reinforcing rings. The two side ribs are arranged longitudinally and are fixedly connected to several annular reinforcing ribs.
[0010] Furthermore, the third reinforcing component includes several bottom ribs, which are evenly distributed at the bottom of the woven bag body and slidably connected to the bottom inner wall of the woven bag body. Both ends of the bottom ribs are fixedly connected to the two inner walls of the bottommost annular reinforcing rib.
[0011] Furthermore, a telescopic rib is laterally fixedly connected to the middle position of several bottom ribs, and the two ends of the telescopic rib are respectively fixedly connected to the bottom of two side ribs.
[0012] Furthermore, a reinforcing sleeve is fixedly connected to the outer wall of the opening of the woven bag body, and the reinforcing sleeve covers the edge of the opening of the woven bag body.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This high-strength, wear-resistant woven bag forms a reinforcing network on the inside of the bag through a first, second, and third reinforcing component. This makes the bag less prone to tearing or deformation when storing heavy objects. At the same time, through the connection between the reinforcing ring and the first reinforcing component, when the bag is pulled by the handle, the pulling force is distributed to the first reinforcing component by the reinforcing ring, thereby preventing the bag from tearing due to the force of the perforation and improving the overall structural strength of the woven bag.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1 - Figure 6A high-strength wear-resistant woven bag includes a woven bag body 1. Two through holes 101 are opened on both sides of the open end of the woven bag body 1. Reinforcing rings 2 are fixedly connected in each of the four through holes 101. A handle 9 is inserted between two reinforcing rings 2 on the same side. A first reinforcing component and a second reinforcing component are connected to the inner wall of the woven bag body 1. The first reinforcing component is connected to the adjacent reinforcing ring 2 and the second reinforcing component. A third reinforcing component is connected to the bottom inner wall of the woven bag body 1. The third reinforcing component is connected to the first reinforcing component and the second reinforcing component.
[0024] like Figure 1 - Figure 6 As shown, the high-strength wear-resistant woven bag of this utility model is structurally similar to existing high-strength wear-resistant woven bags, such as the high-strength wear-resistant color-printed woven bag disclosed in patent publication number CN215324322U. The main improvement of this utility model lies in further enhancing the load-bearing capacity of the woven bag body 1, making the woven bag body 1 less prone to damage or deformation when storing heavy objects and moving it. Figures 1 to 6As shown, in use, the high-strength wear-resistant woven bag of this utility model has its carrying straps 9 threaded through the two reinforcing rings 2 on the same side to form a lifting handle. After placing a heavy object inside the woven bag body 1, the entire woven bag body 1 is lifted by holding the two carrying straps 9. During this process, the reinforcing rings 2 can reinforce the perforations 101 of the woven bag body 1, thereby preventing the perforations 101 from tearing or deforming when lifted. At the same time, the first and second reinforcing components can form a reinforcing mesh on the inner sidewall of the woven bag body 1. The third reinforcing component at the bottom, through its connection with the first and second reinforcing components, provides additional support to the bottom of the woven bag body 1 when bearing heavy objects, thereby preventing the bottom of the woven bag body 1 from being torn or damaged due to the pressure of heavy objects. The connection between the first reinforcing component and the reinforcing rings 2 allows the weight of the heavy object to be transmitted through the third, second, and first reinforcing components. The reinforcing ring 2 is then applied directly to the carrying strap 9 to prevent excessive pressure on the woven bag body 1 from heavy objects, thereby increasing the load-bearing capacity and overall structural strength of the woven bag body 1. This is particularly important in the production of heat-sealed woven bags, as they are prone to deformation and elongation when stretched. The first, second, and third reinforcing components can minimize excessive stress, deformation, tearing, and damage, thus improving the overall structural strength of the woven bag. In the production of this type of woven bag, the raw materials are processed using existing technology to obtain flat yarns, which are then woven into tubular fabric using existing circular looms. After cutting and sewing, the fabric is heat-sealed using existing plate heat-sealing methods. The first, second, and third reinforcing components can be used after the woven bag is heat-sealed to bond the reinforcing structure to the woven bag using hot-pressing technology, forming the entire woven bag body 1.
[0025] like Figure 2 - Figure 6 As shown, the first reinforcing component includes several annular reinforcing ribs 3, which are equidistantly distributed from bottom to top along the bottom of the woven bag body 1. All annular reinforcing ribs 3 are fixedly connected to the inner wall of the woven bag body 1. All annular reinforcing ribs 3 are connected to the second reinforcing component, and the lowest annular reinforcing rib 3 is connected to the third reinforcing component. Through these multiple annular reinforcing ribs 3, a transverse reinforcing structure is formed on the inner side of the woven bag body 1, thereby enhancing the deformation resistance and damage resistance of the woven bag body 1 around its perimeter, preventing damage to the sides of the woven bag body 1 and the resulting fall of stored items.
[0026] like Figure 1 - Figure 6As shown, the second reinforcing component includes four reinforcing ribs 4 and two side ribs 5. The four reinforcing ribs 4 and the two side ribs 5 are all located inside the woven bag body 1. One end of each of the four reinforcing ribs 4 is fixedly connected to the bottom of the four reinforcing rings 2, and the other end extends downward and is fixedly connected to several annular reinforcing ribs 3 and the inner wall of the woven bag body 1. The two side ribs 5 are fixedly connected to the inner walls of the woven bag body 1 on both sides away from the four reinforcing rings 2. The two side ribs 5 are arranged longitudinally and are fixedly connected to several annular reinforcing ribs 3. By connecting and fixing the four reinforcing ribs 4 to the four reinforcing rings 2 respectively, the force of the carrying strap 9 can be transferred to the reinforcing rings 2, and the reinforcing ribs 4 can bear the weight, thereby avoiding excessive downward pulling force on the woven bag body 1 and preventing deformation or damage to the woven bag body 1. At the same time, the four reinforcing ribs 4 are fixed with multiple annular reinforcing ribs 3, which can form a reinforcing mesh on the inner side of the woven bag body 1, thereby further improving the structural strength of the woven bag body 1.
[0027] like Figure 1 - Figure 6 As shown, the third reinforcing component includes several bottom reinforcing strips 6, which are evenly distributed at the bottom of the woven bag body 1 and slidably connected to the inner wall of the bottom of the woven bag body 1. Both ends of the bottom reinforcing strips 6 are fixedly connected to the two inner walls of the bottommost annular reinforcing rib 3. The multiple bottom reinforcing strips 6 are connected and fixed to the bottom annular reinforcing rib 3. When a heavy object presses on the multiple bottom reinforcing strips 6, the downward pressure can be transmitted upward through the annular reinforcing rib 3 and the reinforcing strips 4, thereby preventing the woven bag body 1 from being directly subjected to excessive force and causing damage or deformation. It forms a support at the bottom of the woven bag body 1, improving the load-bearing capacity of the woven bag body 1.
[0028] like Figure 1 - Figure 6 As shown, several bottom reinforcing bars 6 are horizontally fixedly connected to the middle position of telescopic reinforcing bars 7, and the two ends of the telescopic reinforcing bars 7 are fixedly connected to the bottom of two side reinforcing bars 5 respectively. When objects of different sizes are placed inside the woven bag body 1, the two sides of the woven bag body 1 will concave inward or expand outward to varying degrees. At this time, the two sides of the woven bag body 1 can pull the two ends of the telescopic reinforcing bars 7 to stretch or contract to the sides, thereby adapting to the size of the stored items and providing support for the bottom of the stored items.
[0029] like Figure 1 - Figure 4 As shown, a reinforcing sleeve 8 is fixedly connected to the outer wall of the opening of the woven bag body 1, and the reinforcing sleeve 8 wraps around the edge of the opening of the woven bag body 1. Wrapping the edge of the opening of the woven bag body 1 with the reinforcing sleeve 8 can improve the strength of the opening of the woven bag body 1 and prevent deformation or damage to the edge of the opening of the woven bag body 1.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
