Description

Technical Field

[0001] This utility model relates to the field of woven bag technology, specifically to woven bags with moisture-proof function. Background Technology

[0002] Woven bags are widely used packaging containers in agriculture, chemical industry, food, and building materials due to their low cost, high strength, and ease of transportation. Traditional woven bags are usually made of woven materials such as polypropylene (PP) or polyethylene (PE), which do not have good moisture-proof properties. When storing or transporting moisture-sensitive materials (such as fertilizers, seeds, pharmaceuticals, and food), moisture in the environment can easily penetrate into the interior through the pores of the woven bag, causing the contents to absorb moisture, clump, mold, or even become ineffective, seriously affecting product quality and safety. To improve moisture-proof performance, existing technologies often add a plastic inner liner bag (such as a PE film bag) inside the woven bag to form a physical barrier layer.

[0003] However, once such liner bags are sealed, the internal humidity cannot be monitored in real time. When the liner bag fails to seal due to aging, damage, or improper sealing, users often cannot detect it in time and only discover the problem after the contents have become damp and deteriorated. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing a woven bag with moisture-proof function. To solve the above problems, the detection component can monitor and display the humidity changes inside the inner lining bag, facilitating timely moisture-proof measures and effectively preventing the contents from becoming damp and deteriorating. At the same time, the desiccant pack can absorb the moisture inside the inner lining bag and reduce the relative humidity inside the bag.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a woven bag with moisture-proof function, comprising: a woven bag, wherein a bag cavity is provided inside the woven bag, an inner lining bag is provided inside the bag cavity, and a detection component is provided between the woven bag and the inner lining bag. The detection component comprises: a sleeve fixedly connected to one side of the inner lining bag, a filter screen fixedly connected to one end of the sleeve, a threaded tube provided inside the sleeve, a transparent plastic plate fixedly connected to one end of the threaded tube, and a humidity detection card placed inside the threaded tube.

[0006] Preferably, the threaded tube has an external thread on its outer side, and the sleeve has an internal thread that matches the external thread on the outer side of the threaded tube. The threaded tube and the sleeve are threadedly connected.

[0007] Preferably, a rubber ring is fixedly connected to one end of the sleeve, a positioning port is opened on one side of the woven bag, one end of the sleeve passes through the positioning port, and waterproof and breathable membranes are provided on both sides of the humidity detection card.

[0008] Preferably, a Velcro strap b is fixedly connected to the bottom of the inner wall of the bag cavity, a Velcro strap a is fixedly connected to the bottom of the inner lining bag, a placement bag is connected to one side of the inner wall of the inner lining bag, and a fleece Velcro strap is connected to one side of the inner wall of the inner lining bag.

[0009] Preferably, a desiccant packet is placed inside the placement bag, a fabric strip is attached to the top of the placement bag, and a hook-and-loop fastener is attached to one side of the fabric strip.

[0010] Preferably, a chain a is connected to one side of the inner wall of the bag cavity, a zipper chain a is connected to one side of the chain a, and a chain b is connected to the other side of the inner wall of the bag cavity, a zipper chain b is connected to one side of the chain b.

[0011] Preferably, a zipper head is slidably connected to the top of the zipper chain a, and the top of the zipper head is slidably connected to the zipper chain b.

[0012] The advantage of this utility model is that, through the setting of the detection component, the humidity change inside the inner lining bag can be monitored in real time, and the moisture status can be displayed intuitively through the color change of the humidity detection card, which makes it convenient for staff to take ventilation, replacement or drying measures in a timely manner, effectively preventing the contents from getting damp and deteriorating, and improving the moisture-proof reliability of the woven bag during storage and transportation. Secondly, the combination of sleeve, threaded tube, transparent plastic plate and rubber ring not only achieves the sealed installation of the detection components and isolation from the outside world, but also ensures that moisture can only enter through the waterproof and breathable membrane in a controlled manner, avoiding interference from external water vapor or dust with the detection results. At the same time, it supports the convenient replacement of humidity detection cards, and the desiccant pack can absorb the moisture inside the inner liner bag, effectively reducing the relative humidity inside the bag and preventing excessive moisture inside the bag.

[0022] This application provides a woven bag with moisture-proof function. This moisture-proof woven bag can monitor and visually display humidity changes inside the inner lining bag through the setting of a detection component, facilitating timely moisture-proof measures and effectively preventing the contents from becoming damp and deteriorating. Simultaneously, the desiccant pack can absorb moisture inside the inner lining bag, reducing the relative humidity inside the bag. The following provides a detailed description of this moisture-proof woven bag. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of embodiments.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Please see Figure 1-6In this embodiment, a woven bag with moisture-proof function is provided, including: a woven bag 1, a bag cavity 2 inside the woven bag 1, and an inner lining bag 3 inside the bag cavity 2; a detection component disposed between the woven bag 1 and the inner lining bag 3, the detection component including: a sleeve 4 fixedly connected to one side of the inner lining bag 3, a filter screen 401 fixedly connected to one end of the sleeve 4, a threaded tube 403 inside the sleeve 4, a transparent plastic plate 402 fixedly connected to one end of the threaded tube 403, and a humidity detection card 404 placed inside the threaded tube 403.

[0025] Among them, by setting up the detection components, the humidity change inside the inner lining bag 3 can be monitored in real time, and the moisture status can be displayed intuitively by the color change of the humidity detection card 404, which makes it convenient for staff to take ventilation, replacement or drying measures in a timely manner, effectively preventing the contents from getting damp and deteriorating, and improving the moisture-proof reliability of the woven bag 1 during storage and transportation. Secondly, the combined structure of sleeve 4, threaded tube 403, transparent plastic plate 402 and rubber ring 405 not only achieves the sealed installation of the detection components and isolation from the outside world, but also ensures that moisture can only enter through the waterproof and breathable membrane in a controlled manner, avoiding interference from external water vapor or dust with the detection results. At the same time, it supports the convenient replacement of humidity detection card 404, and the desiccant pack 501 can absorb the moisture inside the inner liner bag 3, effectively reducing the relative humidity inside the bag and preventing excessive moisture inside the bag.

[0026] The threaded tube 403 has an external thread on its outer side, and the sleeve 4 has an internal thread that matches the external thread on the outer side of the threaded tube 403. The threaded tube 403 and the sleeve 4 are threadedly connected. A rubber ring 405 is fixedly connected to one end of the sleeve 4. A positioning port 103 is opened on one side of the woven bag 1. One end of the sleeve 4 passes through the positioning port 103. Waterproof and breathable membranes are provided on both sides of the humidity detection card 404.

[0027] When the moisture inside the inner liner bag 3 reaches a certain level, the moisture inside the inner liner bag 3 slowly diffuses into the threaded tube 403 and comes into contact with the humidity detection card 404. The humidity detection card 404 contains cobalt-free and humidity-sensitive ink. When the relative humidity inside the inner liner bag 3 exceeds a preset threshold, the material undergoes a reversible chemical change, causing a significant color change from blue to red. Staff can observe this color change of the humidity detection card 404 through the transparent plastic plate 402 to determine the internal humidity status, so as to take timely measures such as ventilation, relocation, or replacement of the inner liner.

[0028] Among them, the bottom of the inner wall of the bag cavity 2 is fixedly connected with hook and loop fastener b601, the bottom of the inner lining bag 3 is fixedly connected with hook and loop fastener a6, a placement bag 5 is connected to one side of the inner wall of the inner lining bag 3, and a fleece hook and loop fastener 504 is connected to one side of the inner wall of the inner lining bag 3; a desiccant pack 501 is placed inside the placement bag 5, a fabric strip 502 is connected to the top of the placement bag 5, and a hook and loop fastener 503 is connected to one side of the fabric strip 502.

[0029] In use, pull the fabric strip 502 inside the inner lining bag 3, pull the hook and loop fastener 503 down from the side of the fleece fastener 504, and put the desiccant pack 501 into the placement bag 5. Then, reattach the hook and loop fastener 503 to the side of the fleece fastener 504 to complete the placement of the desiccant pack 501. Then, put the material into the inner lining bag 3 and seal the inner lining bag 3 with a sealing machine.

[0030] Then pull the zipper head 203 to open the bag cavity 2, then put the inner lining bag 3 into the bag cavity 2, and let the sleeve 4 pass through the positioning hole 103. At the same time, press the Velcro a6 at the bottom of the inner lining bag 3 onto the Velcro b601 to fix the inner lining bag 3 inside the bag cavity 2.

[0031] Furthermore, the humidity detection card 404 is inserted into the threaded tube 403, and the threaded tube 403 is screwed into the sleeve 4, thus completing the placement of the humidity detection card 404. At this time, the filter screen 401 can prevent the material inside the inner liner bag 3 from directly contacting the humidity detection card 404, while the waterproof and breathable membrane on the humidity detection card 404 can isolate water without affecting the contact between the air inside the inner liner bag 3 and the humidity detection card 404. In addition, the rubber ring 405 can prevent external water or air from entering the inner liner bag 3 and the sleeve 4.

[0032] When the inner liner bag 3 becomes dirty, damaged, or aged due to use, the material inside the inner liner bag 3 can be emptied, and then the inner liner bag 3 can be pulled to disconnect the Velcro a6 and Velcro b601, so that the inner liner bag 3 can be removed separately for replacement or cleaning.

[0033] Among them, a chain belt a101 is connected to one side of the inner wall of the bag cavity 2, and a zipper chain a102 is connected to one side of the chain belt a101. A chain belt b201 is connected to the other side of the inner wall of the bag cavity 2, and a zipper chain b202 is connected to one side of the chain belt b201. A zipper head 203 is slidably connected to the top of the zipper chain a102, and the top of the zipper head 203 is slidably connected to the zipper chain b202.

[0034] Furthermore, both zipper chain a102 and zipper chain b202 have a row of teeth, which are arranged in an alternating pattern. Both rows of teeth have grooves and tooth grooves. The zipper head 203 has a wedge-shaped structure inside, which enables the two rows of teeth to close and separate. When the zipper head 203 is pulled, the tooth grooves of the teeth on zipper chain a102 will embed into the tooth grooves on zipper chain b202, thereby closing zipper chain a102 and zipper chain b202.

[0035] The working principle is as follows: In use, pull the fabric strip 502 inside the inner lining bag 3, pull the hook and loop fastener 503 down from the side of the fleece fastener 504, and put the desiccant pack 501 into the placement bag 5. Then, reattach the hook and loop fastener 503 to the side of the fleece fastener 504 to complete the placement of the desiccant pack 501. Then, put the material into the inner lining bag 3 and seal the inner lining bag 3 with a sealing machine.

[0036] Then pull the zipper head 203 to open the bag cavity 2, then put the inner lining bag 3 into the bag cavity 2, and let the sleeve 4 pass through the positioning hole 103. At the same time, press the Velcro a6 at the bottom of the inner lining bag 3 onto the Velcro b601 to fix the inner lining bag 3 inside the bag cavity 2.

[0037] Furthermore, the humidity detection card 404 is inserted into the threaded tube 403, and the threaded tube 403 is screwed into the sleeve 4, thus completing the placement of the humidity detection card 404. At this time, the filter screen 401 can prevent the material inside the inner liner bag 3 from directly contacting the humidity detection card 404, while the waterproof and breathable membrane on the humidity detection card 404 can isolate water without affecting the contact between the air inside the inner liner bag 3 and the humidity detection card 404. In addition, the rubber ring 405 can prevent external water or air from entering the inner liner bag 3 and the sleeve 4.

[0038] When the moisture inside the inner liner bag 3 reaches a certain level, the moisture inside the inner liner bag 3 slowly diffuses into the threaded tube 403 and comes into contact with the humidity detection card 404. The humidity detection card 404 contains cobalt-free and humidity-sensitive ink. When the relative humidity inside the inner liner bag 3 exceeds a preset threshold, the material undergoes a reversible chemical change, causing a significant color change from blue to red. Staff can observe this color change of the humidity detection card 404 through the transparent plastic plate 402 to determine the internal humidity status, so as to take timely measures such as ventilation, relocation, or replacement of the inner liner.

[0039] When the inner liner bag 3 becomes dirty, damaged, or aged due to use, the material inside the inner liner bag 3 can be emptied, and then the inner liner bag 3 can be pulled to disconnect the Velcro a6 and Velcro b601, so that the inner liner bag 3 can be removed separately for replacement or cleaning.
