Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag technology, specifically to a plastic woven bag with good moisture-proof effect. Background Technology

[0002] Plastic woven bags are primarily made of polypropylene and polyethylene. They are currently widely used in cement, fertilizer, and chemical industries. The main production process involves extruding the raw materials into film, drawing fibers, winding, circular weaving, printing, cutting, and sewing to obtain the finished plastic woven bag. Traditional woven bags are sealed with twine, which needs to be cut when opened. After cutting the twine, the bag often cannot achieve a good secondary seal, making it prone to water seepage in humid environments, leading to mold growth and even insect infestation of the contents. Utility Model Content

[0003] The purpose of this utility model is to provide a plastic woven bag with good moisture-proof effect to solve the problems mentioned in the background art.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: a plastic woven bag with good moisture-proof effect, including a bag body, the top of the bag body is provided with a bag opening, the front and back sides of the upper part of the bag body are provided with a pair of symmetrical folds, the side of the bag body is provided with a fixing block, the fixing block is fixed to the bag body by stitching, the front and back sides of the fixing block are respectively provided with a first clamping plate and a second clamping plate that can be flipped back and forth, and the first clamping plate and the second clamping plate are provided with a protruding clamping block on the side facing the bag body; it also includes a locking member for closing or separating the ends of the first clamping plate and the second clamping plate.

[0005] Using the above technical solution, when sealing the bag opening, the top of the bag is folded along the crease. After bending the crease, the bag opening is sealed. Then, the bent part of the bag is flipped downwards. Next, the first and second clamps are rotated closer together. The clamps on the first and second clamps clamp the bag and the bent part together. Then, the ends of the first and second clamps are locked together by locking devices, thus sealing the bag opening again and achieving a double seal. When it is necessary to open the bag opening, the locking devices unlock and separate the ends of the first and second clamps, and the bag is flipped upwards to restore the bent part. Using the above sealing structure, not only is there a good moisture-proof effect, but a good secondary seal can also be achieved.

[0006] As a further optimization of this utility model, the fixing block is provided with protrusions on both the front and rear sides, and a fixing shaft is provided on the protrusions. The ends of the first clamping plate and the second clamping plate are provided with connecting grooves, and the sidewalls of the connecting grooves are provided with shaft holes and rotatably connected to the corresponding fixing shafts.

[0007] As a further optimization of this utility model, the clamping block is provided with a plurality of magnets.

[0008] Using the above technical solution, when the clamping blocks clamp the bag body and the bent part of the bag body together, the magnets can attract each other, so that the two clamping blocks are tightly attached to each other, which strengthens the seal of the bag opening.

[0009] As a further optimization of this utility model, the inner wall of the bag body is provided with several moisture-proof pockets, each moisture-proof pocket contains moisture-proof particles, each moisture-proof pocket has several through holes, the diameter of the through holes is smaller than the diameter of the moisture-proof particles, the top of the moisture-proof pocket is provided with an opening, and a Velcro closure is provided between the opening and the inner side of the bag body.

[0010] By adopting the above technical solution, a moisture-proof pocket can be placed inside the bag to hold moisture-proof particles. These particles can absorb moisture from inside the bag, further improving the moisture-proof effect.

[0011] As a further optimization of this utility model, the locking member includes a rotatable connecting rod disposed at the end of the first clamping plate, the surface of the connecting rod being provided with external threads, and the end of the second clamping plate being provided with a threaded hole adapted to the connecting rod.

[0012] Using the above technical solution, the rotating connecting rod connects to the threaded hole, thereby closing and fixing the ends of the first clamping plate and the second clamping plate.

[0013] As a further optimization of this utility model, anti-abrasion pads are provided on both sides of the bottom of the bag body, and the anti-abrasion pads are made of rubber.

[0014] Using the above technical solutions, the bottom sides of the bag are prone to tearing, deformation, and damage, and are also easily damaged by external friction. Anti-abrasion pads are installed to protect it and prevent water leakage.

[0015] As a further optimization of this utility model, the bag opening is provided with sealing strips on both sides above the crease.

[0016] By adopting the above technical solutions, a sealing strip is set to achieve a three-layer seal at the bag opening, further improving the bag's sealing performance.

[0017] The beneficial effects of this utility model are as follows: When it is necessary to seal the bag opening, the top of the bag body is folded along the crease. After the crease of the bag body is bent, the bag opening is sealed. Then, the bent part of the bag body is turned downwards. Then, the first clamp and the second clamp are rotated closer to each other. The clamps on the first clamp and the second clamp clamp the bag body and the bent part of the bag body together. Then, the ends of the first clamp and the second clamp are locked together by the locking member, thereby sealing the bag opening again and achieving double sealing. When it is necessary to open the bag opening, the locking member unlocks and separates the ends of the first clamp and the second clamp, and the bent part of the bag body is turned upwards to restore it. The above sealing structure not only has a good moisture-proof effect, but also achieves a good secondary seal. Attached Figure Description

The end of the second clamping plate 42 is provided with a threaded hole 421 that matches the connecting rod 411. The clamping block 44 is provided with a plurality of magnets 8. When the clamping block 44 clamps the bag body 1 and the bent part of the bag body 1 together, the magnets 8 can attract each other, so that the two clamping blocks 44 are pressed tightly together, thereby strengthening the seal on the bag opening 11.

[0026] The inner wall of the bag body 1 is provided with several moisture-proof pockets, and moisture-proof particles are provided in the moisture-proof pockets. The moisture-proof particles are soda lime or calcium chloride. The moisture-proof pockets are provided with several through holes 51.

[0028] Furthermore, the bag opening 11 has sealing strips 7 on both sides above the crease 2, and the sealing strips 7 provide a three-layer seal for the bag opening 11, further improving the sealing performance of the bag body 1.

[0029] The principle of this utility model is as follows: When it is necessary to seal the bag opening 11, the upper part of the bag body 1 is folded along the crease 2. After the crease 2 of the bag body 1 is bent, the bag opening 11 is sealed. Then, the bent part of the bag body 1 is turned down. Then, the first clamping plate 41 and the second clamping plate 42 are rotated closer to each other. The clamping blocks 44 on the first clamping plate 41 and the second clamping plate 42 clamp the bag body 1 and the bent part of the bag body 1 together. Then, the connecting rod 411 is rotated and connected to the threaded hole 421, thereby closing and fixing the ends of the first clamping plate 41 and the second clamping plate 42, thereby sealing the bag opening 11 again and achieving double sealing.

[0030] When it is necessary to open the bag opening 11, the locking member unlocks and separates the ends of the first clamp 41 and the second clamp 42, and flips the bag body 1 upward to restore the bent part. With the above-mentioned sealing structure, it not only has a good moisture-proof effect, but also can achieve a good secondary seal.

[0031] A moisture-proof pocket is placed inside the bag body 1 to hold moisture-proof particles. The moisture-proof particles can absorb moisture inside the bag body 1, further improving the moisture-proof effect.
