Description

Technical Field

[0001] The invention relates to the technical field of packaging bags, and in particular to a packaging bag with a petal-type partition. Background Art

[0002] Bags can be seen everywhere in life. Bags are usually used to hold objects, which can not only play a role in shielding and protection, but also facilitate the packaging and transportation of items. There are many types of bags, such as ton bags commonly used on construction sites, flour bags, rice bags, feed bags, etc. for packaging food. Ordinary packaging bags can only hold a single material or a mixture of materials that do not react with each other, but in some applications, two or more materials need to be packed in proportion. For this reason, people can easily think of instant noodle packaging, that is, the method of outer bag inside inner bag. Although this packaging bag with inner bag in outer bag can hold several materials of different properties, it is not uncomfortable for the situation of less materials and manual unpacking, but it is obviously not suitable for large-scale industrial production that requires improved efficiency and less manual operation, and it is even less suitable for continuous operation in industrial production. For example, in the construction industry, dry cement and wet sand and gravel cannot be mixed and packed in bags and transported and stored like bagged cement, because cement will react chemically with the water in the sand and gravel to form agglomerates. If a large bag is used to cover a small bag, packing and unpacking will take a lot of time; sand particles in dry mortar and powdered materials such as cement often separate during bulk transportation and use, which seriously affects the quality of mortar; when making rice and flour fancy foods, rice noodles and flour can only be packaged and used separately, and cannot be packed in the same packaging bag in advance according to a certain proportion for transportation, because mixed rice noodles with different fineness are easy to separate during transportation, or two materials with different water content will stick together, affecting the quality of subsequent products; similarly, corn and wheat with different particle sizes are not easy to transport together. When filling different materials, in order to avoid mixing in advance, it is necessary to use one bag to hold several materials of different properties, and at the same time, it is convenient to unload. Because this can make full use of resources and save resources, it will not cause an increase and waste in the use of packaging bags, and it is more conducive to subsequent work. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a packaging bag with a petal-type partition layer which can contain at least two materials at the same time without mixing the materials with each other.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The packaging bag with a split-flap partition comprises a bag body, wherein the upper end of the bag body is provided with a feed inlet, the lower end of the bag body is provided with a discharge outlet, the bag body is connected to the split-flap partition, and the split-flap partition divides the bag body into an upper bag and a lower bag.

[0006] The above-mentioned packaging bag with a split-flap partition is preferably composed of a plurality of overlapping sheets, one end of the overlapping sheet is a fixed end, the fixed end is fixedly connected to the feed port, and the other end is a movable end, and the movable end can be freely flipped around the fixed end.

[0007] In the packaging bag with the petal-type interlayer, preferably, the overlapping sheets are overlapped and arranged in sequence around the feed opening, and the connection parts of adjacent overlapping sheets form overlapping overlapping parts.

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of this application.

[0024] like Figures 1 to 5 As shown, the packaging bag with a split-flap interlayer of this embodiment comprises a bag body 1, a material inlet 11 is provided at the upper end of the bag body 1, a material outlet 12 is provided at the lower end of the bag body 1, and a split-flap interlayer 2 is connected to the bag body 1, and the split-flap interlayer 2 separates the bag body 1 into an upper bag 13 and a lower bag 14. Through the isolation effect of the split-flap interlayer 2, two different materials can be accommodated in the bag body 1 at the same time, which can not only save the use of packaging bags and speed up the packaging speed, but also achieve the purpose of simultaneously and quickly unloading materials of different properties, greatly improving the efficiency of industrial mass production.

[0025] In this embodiment, the petal-type partition 2 is composed of a plurality of overlapping sheets 23, one end of the overlapping sheet 23 is a fixed end 21, the fixed end 21 is fixedly connected to the feed port 11, and the other end is a movable end 22, and the movable end 22 can be freely turned around the fixed end 21. Before loading, the movable end 22 is turned to the outside of the feed port 11, and the first material is filled into the lower bag 14. After the lower bag 14 is filled, the overlapping sheets 23 are turned over and overlapped into the bag body 1 in sequence to form an upper bag 13, and the upper bag 13 is filled with the second material.

[0026] In this embodiment, the overlapping pieces 23 are overlapped and arranged in sequence around the feed port 11, and the connection between adjacent overlapping pieces 23 forms an overlapping overlap portion.

[0027] In this embodiment, the number of overlapping sheets 23 is at least 2, the width of the overlapping portion of adjacent overlapping sheets 23 is at least 5% of the width of the overlapping sheets 23, and the length of the overlapping sheets 23 is greater than the radius of the circle of the cross section of the bag body 1 and less than the length of the bag body 1, ensuring that the overlapping sheets 23 overlap and close each other, thereby isolating the upper bag 13 and the lower bag 14.

[0028] In this embodiment, the overlapping sheet 23 is made of a flexible material, preferably a waterproof and breathable flexible material, such as waterproof Oxford cloth, PTFE composite cloth, etc., which can prevent mutual leakage between the upper bag 13 and the lower bag 14 and facilitate the folding of the overlapping sheet 23.

[0029] In this embodiment, a first tether 3 for tying the feed inlet 11 is provided at the feed inlet 11. After untying the first tether 3, the material in the bag can be quickly filled, and tightening the first tether 3 can tighten the feed inlet 11.

[0030] In this embodiment, a second tether 4 is provided at the discharge port 12 for tying the discharge port 12. After the second tether 4 is untied, the material in the lower bag 14 can fall out quickly, and the petal-type partition 2 loses the support of the material in the lower bag 14, and the material in the upper bag 13 immediately presses the petal-type partition 2 open and falls out quickly, so that the different materials in the lower bag 14 and the upper bag 13 can be discharged quickly and automatically in sequence.

[0031] In this embodiment, the bag body 1 is also fixed with a lifting ring 5, which is convenient for lifting and transportation of the bag body 1, and also makes the packaging bag in an upright state during transportation and storage, ensuring that the moisture of the water-containing material in the lower bag will not affect the dry material in the upper bag.

[0032] When the packaging bag with a split-type interlayer of this embodiment is used in the production of concrete mix materials, the sand and gravel are in a wet state, and the cement, fly ash, and admixtures are in a dry state. At this time, the material composition (mixing ratio) of each cubic meter of C30 concrete is: 260 kg of cement, 80 kg of fly ash, 3 kg of naphthalene powder water reducer, 820 kg of wet river sand, and 1090 kg of wet pebbles. During production and packaging, tighten the discharge port 12, turn the overlapping sheet 23 to the outside of the bag body 1, fix the lifting ring 5 on the packaging machine, first load 820kg of wet river sand and 1090kg of wet pebbles into the lower bag 14 of the bag body 1, then turn the overlapping sheet 23 made of waterproof flexible material into the bag body 1, and overlap them in sequence to form an upper bag 13. At this time, load 260kg of weighed cement, 80kg of fly ash, and 3kg of naphthalene powder water reducer into this upper bag 13, and finally tighten the feed port 11 to obtain 1 cubic meter of C30 concrete mix material. Because the waterproof overlapping sheet 23 blocks the contact between the moisture of the sand and gravel and the cement, it can be stored for a period of time, and the transportation is also very convenient. It can be stored in a warehouse or a construction site. When it is necessary to pour C30 concrete, hoist the above C30 mix material into the mixer, add 120kg of water in the mix ratio and stir to obtain C30 concrete, which can be pumped and poured. It is very convenient to mix and use immediately.

[0033] When the packaging bag with a split-flap interlayer of this embodiment is used in the production of dry-mixed mortar, the raw materials are wet river sand and dry powder materials such as cement, admixtures, and additives. When using the packaging bag of the present invention to produce dry-mixed mortar, tighten the discharge port 12, turn the overlapping sheet 23 to the outside of the bag body 1, and fix the lifting ring 5 on the packaging machine. First, put the wet river sand weighed according to the mortar mix ratio into the lower bag 14 of the bag body 1, and then turn the overlapping sheet 23 made of waterproof flexible material into the bag body 1, overlap in turn to form an upper bag 13, and put the weighed cement, admixtures, and additives into this upper bag 13. Finally, tighten the feed port 11 to obtain bagged dry-mixed mortar, which can be stored in a warehouse or in a pile shed on the construction site. When the construction site needs to use mortar, the above-mentioned bagged dry-mixed mortar is hoisted into the mixer, and the mortar product is obtained by adding water in the mix ratio and stirring. It is very convenient to mix as needed. This packaging bag allows wet river sand to be used to produce dry mortar without drying, greatly saving equipment investment and drying costs. It is both energy-saving and environmentally friendly, and at the same time solves the problem of material segregation during bulk transportation and use of dry mortar produced from original dry sand.

[0034] The packaging bag with the split-flap compartment can also be used for the quick simultaneous loading and unloading of rice and flour in the food industry, and the quick simultaneous loading and unloading of materials such as corn and soybeans in the feed industry.

[0035] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and changes obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
