Background
The container bag is one kind of container unit, and can be transported by means of crane or forklift, and is suitable for transporting bulk granular material or liquid, and may be used widely in food, grain, medicine, chemical industry and mineral product.
The flexible freight bag in the prior art is made of PP bags, PE bags or composite bags, and is usually spliced rarely, the height of the common flexible freight bag exceeds 200cm, the whole flexible freight bag is of a whole structure, namely the whole PP bag surface or PE bag surface is not spliced in the middle, but the splicing condition can also occur in the actual processing process. The common fixing structure is that two pieces of bag are overlapped at the end positions in a common mode and then fixed by hot pressing, but the structure is poor in stability and is easy to tear. As a technical improvement, the technical staff of the enterprise is improved, and the invention is specially applied for creation.
Disclosure of utility model
In order to solve the problems in the prior art, the utility model provides a double-end spliced PE flexible freight bag connecting structure which can overcome the defects.
The utility model relates to a double-end spliced PE flexible freight bag connecting structure, which comprises a PE bag surface and a PP bag surface; the PE bag surface and the PP bag surface are both designed into a cylinder shape and spliced up and down; the upper edge of the PP bag face is turned outwards to form a turning edge; the lower edge of the PE bag surface is covered on the outer side of the turnover edge and is fixed in a hot pressing mode to form a spliced residual edge; the total height of the PE bag surface and the PP bag surface is more than 200cm.
Further, an intermediate layer is arranged between the splicing residual edge and the PP bag surface.
Further, the overlapping positions of the PP bag surface and the middle interlayer and the splicing margin are fixed through sewing threads.
Further, the height of the cylindrical structure formed by the PE bag surface and the PP bag surface is 320cm.
Further, the width of the spliced redundant edge is 5cm.
Further, the middle interlayer is a PP strip or a PE strip or a polyester layer.
This design still provides a flexible container, including the bag body that the aforesaid double-end concatenation PE flexible container connection structure formed, set up the feed inlet on the bag body, bag body bottom surface sets up the discharge gate.
Furthermore, binding ropes are arranged on the feeding hole and the discharging hole.
Further, sealing cloth pieces are arranged in the feeding hole and the discharging hole.
The flexible freight bag is designed, the structure is unique, the design is ingenious, the designed splicing structure is stable, and meanwhile, the flexible freight bag with the splicing structure is good in tightness and beneficial to processing.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a schematic view of a spliced margin layer structure.
Fig. 3 is a schematic diagram of the structure of the bag.
The diagram is: 1PE bag face, 2PP bag face, 3 concatenation redundant edges, 4 intermediate layer, 21 turn over hem, 4 intermediate layer, 5 sewing thread, 6 feed inlet, 7 discharge gate, 8 binding rope, 9 sealed cloth.
Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
