Description

An inner support flip-type packaging bag

technical field

The utility model relates to the technical field of packaging bags, in particular to an inner-supporting flip-type packaging bag.

Background technique

As an important petrochemical product, asphalt has been widely used in the fields of road and engineering construction. The annual output of asphalt in my country is about 25 million tons. For a long time, the traditional packaging method of asphalt is paper bags or iron drums. Due to its inherent characteristics and the requirements of storage and transportation, there are special requirements for its packaging. Iron drums generally cost more and occupy more space, and they often need to be heated repeatedly during use, which increases transportation costs, and cannot avoid leakage accidents. Asphalt often adheres to the asphalt barrels, causing waste; while in the prior art, double-layer asphalt packaging bags are generally bonded and fixed, and when the inner bag is damaged, the load-bearing capacity of the outer bag is often greatly reduced, and It is inconvenient for the unloading of asphalt, resulting in a decrease in the efficiency of transportation operations.

Utility model content

The purpose of this utility model is to solve the above-mentioned deficiencies of the prior art, and proposes an inner-support flip-type packaging bag, including a packaging bag body, and the packaging bag body is a double-layer structure, which are an outer bag and an inner bag respectively; The inner diameter of the outer bag body is larger than the inner diameter of the inner bag body, and the top edge of the inner bag and the top edge of the outer bag are connected together by sewing, bonding or heat sealing;

The bag mouth of the inner bag is sewn with an elastic binding opening, the end of the elastic binding opening forms a feeding port, the end of the elastic binding opening is provided with a drawstring hole, and the drawstring hole is also provided with a top pull A rope is used to fasten the mouth of the inner bag; magnet pieces are arranged in the outer ring of the bottom and top openings of the outer bag.

Preferably, suspenders are vertically arranged around the top of the outer bag.

Preferably, the packaging bag body is made of canvas or cotton.

Preferably, a reinforcing base cloth is circumferentially sewn on the periphery of the joint portion between the inner bag and the outer bag.

The beneficial effects of the present utility model are as follows:

(1) The packaging bag of the present invention is provided with metal sheets in the top, outer ring and bottom of the outer bag, and cooperates with the unloading mechanism. During the unloading process, the outer bag can be attached to the unloading mechanism due to the action of the magnet sheet. The inner bag will be automatically turned downward with the action of gravity, and the material will be automatically discharged from the feeding port, which makes the whole discharging process more convenient and efficient, and the discharging efficiency is high;

(2) The inner bag is semi-separated and arranged inside the outer bag. When the inner bag is damaged or the outer bag is damaged, compared with the traditional double-layer packaging bag, the packaging bag of the present invention can more conveniently separate the inner bag and the outer bag. Disassembled, the packaging bag can be reused many times, reducing the use cost of the packaging bag.

Detailed ways

In order to deepen the understanding of the present utility model, the present utility model will be described in further detail below with reference to the embodiments and the accompanying drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

Referring to FIG. 1, the present utility model proposes an inner-supporting flip-type packaging bag, including a packaging bag body, the packaging bag body is a double-layer structure, and is an outer bag 1 and an inner bag 2 respectively; the outer bag 1 bag The inner diameter of the body is larger than the inner diameter of the bag body of the inner bag 1, and the top edge of the inner bag 2 and the top edge of the outer bag 1 are sewed, bonded or heat-sealed together;

The inner bag 2 is sewn with an elastic band opening 21, the end of the elastic band opening 21 is provided with a drawstring hole, and the drawstring hole is also provided with a hole for tying the inner bag opening tightly. The top drawstring 22; the bottom 12 of the outer bag and the outer ring 11 of the top opening are provided with magnet pieces.

Preferably, suspenders 4 are vertically arranged around the top of the outer bag 1 .

Preferably, the packaging bag body is made of canvas or cotton.

Preferably, a reinforcing base cloth (not shown) is circumferentially sewn on the periphery of the joint portion 3 between the inner bag 2 and the outer bag 1 .

When in use, first put the packaging bag into the unloading mechanism through a hoist. The unloading structure has an inversion bucket matching the packaging bag, and the packaging bag is placed in the inversion bucket. The inversion bucket has an opening corresponding to the bottom 12 and the top of the packaging bag. The electromagnet device matched with the magnet pieces in the outer ring 11 can fix the bottom 12 of the outer bag to the bottom of the overturning bucket, and fix the top of the outer bag to the mouth of the overturning bucket; when unloading, the overturning bucket is turned over, and the inner bag 2 is separated from the outside At the same time as the bag is turned down, the material is also poured out.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the within the scope of protection of the present invention.
