Description

Technical Field

[0001] This utility model relates to the field of woven bag technology, and in particular to a moisture-proof and breathable woven bag. Background Technology

[0002] Woven bags, widely used in industrial and agricultural sectors, are flexible containers with a certain strength, made from polymer materials such as polyethylene and polypropylene through warp and weft weaving. They are commonly used for the transportation and storage of granular and powdery materials. Their core functional requirements are concentrated in three aspects: load-bearing strength, moisture-proof performance, and breathability. Among these, balancing moisture-proof and breathability has always been a technical challenge.

[0003] Existing woven bags have significant functional defects. While the traditional single-layer woven structure offers good air permeability, the large gaps between fibers fail to block external moisture, making the internal materials prone to moisture absorption and deterioration in high-humidity environments. To improve moisture resistance, most products employ a single-layer lamination process, where a polyethylene film is laminated onto the woven layer. Although this can block external moisture intrusion, the sealed structure prevents moisture inside the bag, such as water vapor from material respiration and condensation caused by temperature differences, from escaping. Long-term storage can easily lead to mold growth and clumping. To address these issues, existing technologies attempt to create micron-sized pores on the lamination surface, trying to balance breathability and moisture resistance. However, the pore size is difficult to control precisely; if the pore size is too large, moisture resistance fails, and if it is too small, air permeability is insufficient. Ultimately, a balance between moisture resistance and breathability cannot be achieved. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a moisture-proof and breathable woven bag, which aims to improve the problem in the prior art where the size of the pores is difficult to control precisely, the pores are too large and the moisture-proof effect fails, and the air permeability is insufficient, so it is still impossible to achieve a balance between moisture-proof and breathability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a moisture-proof and breathable woven bag, comprising an outer layer of the bag, wherein a sandwich mechanism is fixedly connected to the inner side of the outer layer of the bag, the sandwich mechanism serving to balance breathability and moisture-proofness, and a storage mechanism installed at the bottom of the outer layer of the bag, the storage mechanism serving to store the woven bag, wherein the sandwich mechanism includes a moisture-proof layer, the moisture-proof layer being fixedly connected to the inner side of the outer layer of the bag, a skeleton assembly being fixedly connected to the inner side of the moisture-proof layer, and a flow guiding component being fixedly connected to the inner side of the skeleton assembly.

[0007] The skeleton assembly includes a honeycomb layer, which is fixedly connected to the inner side of the moisture-proof layer, and multiple moisture-absorbing meshes are fixedly connected at equal intervals inside the honeycomb layer.

[0008] As a further description of the above technical solution:

[0009] The flow guiding component includes a flow guiding layer, which is fixedly connected to the inner side of the honeycomb layer. Multiple flow guiding grooves are equidistantly opened on the outer wall of the flow guiding layer, and multiple reinforcing ribs are equidistantly fixedly connected to the inner side of the outer wall of the flow guiding groove.

[0010] As a further description of the above technical solution:

[0011] The storage mechanism includes a roll, which is located at the bottom of the outer layer of the bag. A threaded sleeve is threaded to the right end of the roll, and a limit block is threaded to the left end of the roll. A metal clip is rotatably connected to the right side of the limit block. An I-shaped groove is formed on the top of the outer wall of the roll, and a connecting component is slidably connected to the inner wall of the I-shaped groove.

[0012] As a further description of the above technical solution:

[0013] The connecting assembly includes a connecting strip that is slidably connected to the inner wall of the I-beam groove, and both ends of the connecting strip are threaded with fastening bolts.

[0014] As a further description of the above technical solution:

[0015] A connecting bottom strap is fixedly connected to the bottom of the outer layer of the bag. The connecting bottom strap is installed on the top inner wall of the connecting strip. Hanging rings are fixedly connected to the four corners of the top of the outer layer of the bag.

[0016] As a further description of the above technical solution:

[0017] The limiting block has a rotating groove on its rear side, and the metal clip is rotatably connected to the inner wall of the rotating groove.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the threaded sleeve is provided with anti-slip teeth, and the metal clip is located at the rear left end of the drum.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the outer layer of the bag initially isolates external moisture factors, the moisture-proof layer prevents a large amount of water from entering while ensuring breathability, the honeycomb layer provides a channel for air circulation, the moisture-absorbing mesh absorbs the moisture that permeates from the outer layer, the guide groove can absorb condensation, and the reinforcing ribs improve the structural stability when bearing weight. This structure adds multiple moisture-proof measures while ensuring breathability and accelerating air circulation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a moisture-proof and breathable woven bag, comprising an outer layer 1 of the bag, an interlayer mechanism 2 fixedly connected to the inner side of the outer layer 1, the interlayer mechanism 2 serving to balance breathability and moisture-proofness, and a storage mechanism 3 installed at the bottom of the outer layer 1, the storage mechanism 3 serving to store the woven bag.

[0032] The interlayer mechanism 2 includes a moisture-proof layer 201, which is fixedly connected to the inner side of the outer layer 1 of the bag. A skeleton assembly 202 is fixedly connected to the inner side of the moisture-proof layer 201, and a flow guiding assembly 203 is fixedly connected to the inner side of the skeleton assembly 202.

[0033] The skeleton component 202 includes a honeycomb layer 2021, which is fixedly connected to the inner side of the moisture-proof layer 201. Multiple moisture-absorbing nets 2022 are fixedly connected at equal intervals inside the honeycomb layer 2021.

[0034] The flow guiding component 203 includes a flow guiding layer 2031, which is fixedly connected to the inner side of the honeycomb layer 2021. Multiple flow guiding grooves 2032 are equidistantly opened on the outer wall of the flow guiding layer 2031, and multiple reinforcing ribs 2033 are equidistantly fixedly connected to the inner side of the outer wall of the flow guiding grooves 2032.

[0035] Specifically, the outermost layer 1 of the bag is located on the outermost side of the woven bag structure and is in direct contact with the external environment. It initially isolates the bag from external moisture through its own structure. The outer surface of the moisture-proof layer 201 has evenly distributed micro-pores with tiny diameters, which prevent a large amount of moisture from entering the interior while maintaining the overall breathability of the structure. The skeleton component 202, as the skeleton layer of the entire woven bag, is located inside the moisture-proof layer 201. The honeycomb layer 2021 is fixedly connected to the adjacent layers above and below with hot melt adhesive to form multiple relatively stable hollow hexagonal cavities. These cavities provide channels for internal air circulation. Meanwhile, a moisture-absorbing net 2022 is fixed inside the honeycomb layer 2021. The moisture-absorbing net 2022 is a soft moisture-absorbing material with a through hole in the middle, which can absorb moisture that permeates from the outer layer while ensuring air permeability. A flow-guiding layer 2031 is attached to the inner side of the honeycomb layer 2021. The outer surface of the flow-guiding layer 2031 is provided with multiple flow-guiding grooves 2032, which can absorb the condensed water and guide it to discharge. The inner surface of the flow-guiding layer 2031 is covered with reinforcing ribs 2033. The structural stability of the woven bag under load can be improved by the support of the reinforcing ribs 2033.

[0036] Reference Figure 4 and Figure 5The storage mechanism 3 includes a roll 301, which is located at the bottom of the outer layer 1 of the bag. The right end of the roll 301 is threadedly connected to a threaded sleeve 302, and the left end of the roll 301 is threadedly connected to a limit block 303. A metal clip 304 is rotatably connected to the right side of the limit block 303. An I-shaped groove 305 is provided on the top of the outer wall of the roll 301, and a connecting component 306 is slidably connected to the inner wall of the I-shaped groove 305.

[0037] The connecting component 306 includes a connecting strip 3061, which is slidably connected to the inner wall of the I-beam groove 305. Both the left and right ends of the connecting strip 3061 are threaded with fastening bolts 3062.

[0038] A rotating groove 6 is provided on the rear side of the limiting block 303, and a metal clip 304 is rotatably connected to the inner wall of the rotating groove 6. An anti-slip tooth 7 is provided on the outer wall of the threaded sleeve 302, and the metal clip 304 is located at the rear left end of the drum 301.

[0039] Specifically, the connecting bottom strap 4 at the bottom edge of the outer layer 1 of the bag is slid into the internal channel of the connecting strip 3061 along one end opening. After the connecting bottom strap 4 is fully inserted and installed, the two fastening bolts 3062 on both sides are rotated. One end of their screws continuously screws into the screw hole of the connecting strip 3061, pressing the connecting bottom strap 4 tightly against the inner wall surface of the connecting strip 3061, thus completing the fixed connection between the outer layer 1 of the bag and the connecting strip 3061. Then, the threaded sleeve 302 is unscrewed from the threaded section at the end of the roll 301, and the bag body is removed. The connecting strip 3061 of the outer layer 1 is aligned and installed into the I-groove 305 on the side of the roll 301. Then, the threaded sleeve 302 is reinstalled back onto the end of the roll 301 outside the connecting strip 3061. At this time, the free end of the outer layer 1 of the bag is held by hand and rolled up along the circumference of the roll 301 to form a compact roll. After the roll is finished, the metal clip 304 on one side of the roll 301 is rotated. The metal clip 304 is an elastic metal, and its end can tightly press the exposed end of the outer layer 1 of the bag after it is rolled up, keeping it rolled up and preventing it from loosening on its own.

[0040] Reference Figure 4 and Figure 5 A connecting bottom strap 4 is fixedly connected to the bottom of the outer layer 1 of the bag. The connecting bottom strap 4 is installed on the top inner wall of the connecting strip 3061. A hanging ring 5 is fixedly connected to the top four corners of the outer layer 1 of the bag.

[0041] Specifically, the bottom strap 4 does not contain any materials. Its function is to connect the outer layer 1 of the bag and its inner structure to the storage mechanism 3. The lifting ring 5 is used to lift the outer layer 1 of the bag for subsequent operations. The structure is sturdy.

[0042] Working principle: The outermost layer 1 of the bag is the outermost layer of the woven bag, which is in direct contact with the outside world and initially isolates it from external moisture. The surface of the moisture-proof layer 201 is evenly distributed with tiny micro-pores, which allow a large amount of moisture to enter while maintaining breathability. The skeleton component 202 is the skeleton layer, in which the honeycomb layer 2021 is fixed to the upper and lower layers with hot melt adhesive to form multiple relatively stable hollow hexagonal cavities, providing channels for air circulation. At the same time, a moisture-absorbing net 2022 is fixed inside. The moisture-absorbing net 2022 is a soft moisture-absorbing material with holes in the middle, which can absorb water that seeps in from the outer layer while ensuring breathability. The honeycomb layer 2021 has a flow guide layer 2031 on the inside and multiple flow guide grooves 2032 on the outside of the flow guide layer 2031, which can absorb condensate and discharge it in a concentrated manner. The inner surface of the flow guide layer 2031 is covered with reinforcing ribs 2033, which can improve the structural stability under load. This structure adds multiple moisture-proof measures while taking into account breathability and accelerating air circulation. It no longer relies solely on opening micron-level vent holes for ventilation. It solves the problem in the existing technology that it is difficult to accurately control the pore size. If the pore size is too large, the moisture-proof effect will fail. If it is too small, the ventilation will be insufficient, and it is still impossible to achieve a balance between moisture-proof and breathability.

[0043] The outer layer 1 of the bag, specifically the connecting bottom strap 4 at the bottom of the outer layer 1, is slid into one end of the connecting strip 3061. After installation, the two fastening bolts 3062 are rotated, and their ends continuously press the connecting bottom strap 4 against the inner wall of the connecting strip 3061, completing the connection between the outer layer 1 of the bag and the connecting strip 3061. Next, the threaded sleeve 302 is unscrewed from the drum 301, and the connecting strip 3061 is installed into the I-beam groove 305. The connecting strip 3061 is then reinstalled. At this point, the outer layer 1 of the bag is rolled up along the drum 301 and stored in a roll shape. After completion, the metal clip 304 is rotated. The metal clip 304 is made of elastic metal and can press the end of the rolled-up outer layer 1 of the bag to keep it in a rolled state without loosening. This mechanism can realize the quick storage of the outer layer 1 of the bag, which can save storage space, protect the integrity of the internal structure and function of the woven bag, and facilitate quick access.
