Hanging-belt type moisture-proof flexible freight bag and manufacturing method thereof
Technical Field
The invention relates to the technical field of flexible freight bags, in particular to a sling type moisture-proof flexible freight bag and a manufacturing method thereof.
Background
The container bag is also called flexible container bag, ton bag, space bag, etc. and is one kind of container unit, and when it is matched with crane or fork truck, it can implement container unit transportation, and is suitable for shipping bulk powder material. The flexible container is widely used for transporting and packaging powdery, granular and blocky articles such as food, grain, medicine, chemical industry, mineral products and the like, and is generally used as a packaging product for transportation and storage in developed countries.
The application range of the flexible freight bag in China is expanding, so the market demand potential of the flexible freight bag product is very large, and the development prospect is very wide. The existing flexible freight bag body is composed of an inner layer and an outer layer, the inner bag is a polyethylene film, the outer bag is a compound film plastic woven bag, the air permeability of the flexible freight bag is poor, and if the flexible freight bag is used for transporting and packaging crops, the crops are easy to rot and deteriorate due to the fact that the crops are affected with damp and air is not circulated in the transportation process.
Chinese patent CN201566985U discloses a ventilative and ventilated flexible freight bag, the flexible freight bag includes the bag body, and the top surface of the bag body is uncovered, and bag body top surface four corners department is connected with the suspension clasp, and the left and right sides and the bottom surface of the bag body are the load-bearing part, and the load-bearing part comprises ventilative cloth, and the front and back two sides of the bag body comprise eyelet fabric, and eyelet fabric and load-bearing part pass through the sewing thread seam of excelling in. The air permeable packing box can play a role in air permeability, but the top of the air permeable packing box is open, so that crops are easy to scatter in the packing and transporting process.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides the hanging belt type moisture-proof flexible freight bag which has the moisture-proof function, good ventilation and air permeability and high safety factor and can effectively ensure the freshness of crops in the transportation process.
In order to achieve the technical purpose, the invention adopts the following technical scheme:
a hanging-belt type moisture-proof flexible freight bag and a manufacturing method thereof comprise a bag body and a feed inlet, wherein a plurality of vertically-arranged hollow groove-shaped partition strips are arranged on the inner side of the side wall of the bag body, the bottom end of each hollow groove-shaped partition strip extends to be close to the bottom of the bag body, the top end of each hollow groove-shaped partition strip extends out of the bag body, air holes are uniformly distributed on the surfaces of the hollow groove-shaped partition strips, granular edible drying agents are filled in the air holes, hanging belts are further arranged at the top of the bag body.
Furthermore, the top of the hollow groove-shaped division bar is bent and extends out of the side wall of the upper part of the bag body.
As one improved technical scheme of the invention, the inside of the side wall of the bag body is provided with the breathable cloth, and the hollow groove-shaped division bar is positioned between the breathable cloth and the inside of the side wall of the bag body.
As another improved technical scheme of the invention, the hollow groove-shaped division bars are woven by adopting breathable cloth, and the lower ends and the top ends of the division bars are of closed structures.
Advantageous effects
According to the invention, the hollow groove-shaped parting strips filled with granular food drying agents are arranged on the inner side of the side wall of the bag body, and when the feed inlet and the discharge outlet of the bag body are both closed, air in the bag body can keep ventilation and air permeability with the outside through the hollow groove-shaped parting strips; on one hand, the breathable cloth can prevent food from colliding in the packaging and transporting process, can effectively isolate the food from the hollow groove-shaped partition bars, avoids the edible drying agent and the food from being mixed in a cross mode, and can effectively prevent granular food from entering the hollow groove-shaped partition bars, so that the hollow groove-shaped partition bars are blocked, and the breathable effect is influenced.

Detailed Description
The breathable packaging bag of the present invention will now be described in detail with reference to specific embodiments.
Example 1
As shown in fig. 1 and 2, the sling type moisture-proof flexible freight bag comprises a bag body 1 and a feed inlet 2, wherein a plurality of vertically arranged hollow groove-shaped partition strips 3 are arranged on the inner side of the side wall of the bag body 1, the bottom ends of the hollow groove-shaped partition strips 3 extend to be close to the bottom of the bag body 1, the top ends of the hollow groove-shaped partition strips 3 extend out of the bag body 1, vent holes 31 are uniformly distributed on the surface of the hollow groove-shaped partition strips 3, and granular edible drying agents 4 are filled in the hollow groove-shaped partition strips 3. In this embodiment, the top of the hollow groove-like division bar 3 is bent and extends out of the side wall of the upper portion of the bag body 1. The inside of the side wall of the bag body 1 is provided with a piece of breathable cloth 5, and the hollow groove-shaped division bar 3 is positioned between the piece of breathable cloth 5 and the inside of the side wall of the bag body 1. The discharge port 6 is arranged at the bottom of the bag body 1, so that the container bag is convenient to unload. Meanwhile, the feed inlet 2 and the discharge outlet 6 are provided with closing ropes (21, 61), so that the feed inlet 2 and the discharge outlet 6 can be closed conveniently and rapidly. The top of the bag body 1 is also provided with a hanging strip 7, and the hanging strip 7 is sewed on the bag body 1, so that the carrying of the flexible freight bag is convenient.
Example 2
As shown in fig. 3 and 4, the sling type moisture-proof flexible freight bag comprises a bag body 1 and a feed inlet 2, wherein a plurality of vertically arranged hollow groove-shaped partition strips 3 are arranged on the inner side of the side wall of the bag body 1, the bottom ends of the hollow groove-shaped partition strips 3 extend to be close to the bottom of the bag body 1, the top ends of the hollow groove-shaped partition strips 3 extend out of the bag body 1, and granular edible desiccant 4 is filled in the hollow groove-shaped partition strips 3. The hollow groove-shaped division bar is woven by adopting breathable cloth, and the lower end and the top end of the division bar are of closed structures so as to prevent the edible drying agent from scattering. The top of the hollow groove-shaped division bar 3 is bent and extends out of the side wall of the upper part of the bag body 1. The discharge port 6 is arranged at the bottom of the bag body 1, so that the container bag is convenient to unload. Meanwhile, the feed inlet 2 and the discharge outlet 6 are provided with closing ropes (21, 61), so that the feed inlet 2 and the discharge outlet 6 can be closed conveniently and rapidly. The top of the bag body 1 is also provided with a hanging strip 7, and the hanging strip 7 is sewed on the bag body 1, so that the carrying of the flexible freight bag is convenient. Because the hollow groove-shaped division bar 3 in the embodiment is made of the breathable cloth, the purposes of preventing crops from colliding and preventing the edible drying agent 4 from being mixed with the crops in a cross way can be achieved without covering a layer of breathable cloth 5 on the division bar.
Appropriate changes and modifications to the embodiments described above will become apparent to those skilled in the art from the disclosure and teachings of the foregoing description. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and variations of the present invention should fall within the scope of the claims of the present invention.
