Description

Technical Field

[0001] The utility model relates to the field of woven bags, in particular to a sandwich composite woven bag. Background Art

[0002] A woven bag is a bag that is woven by straightening plastic. One type of woven bag is formed by connecting a PE bag at the inner liner to form a sandwich woven bag, which can effectively improve the moisture-proof performance of the woven bag.

[0003] In the prior art, the connection of PE bags includes directly putting them on the inside of the woven bag, or folding the top part of the woven bag inward to form a edging on the top edge of the PE bag, and then sewing to achieve the connection. The above second connection method can form a stable connection for the PE bag.

[0004] However, when the woven bag is in use and carries a high weight, the weft of the woven bag is prone to cracking, and the warp is prone to excessive stretching and local breakage. Utility Model Content

[0005] The purpose of the present invention is to provide a sandwich composite woven bag in order to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a sandwich composite woven bag, comprising a woven bag, a PE bag is sleeved on the inner side of the woven bag, a plurality of band-shaped woven strips are integrally formed on the outer circumference of the PE bag, the woven bag is woven with through holes for the woven strips to pass through, and a bottom support is integrally formed at the ends of the plurality of woven strips, and the bottom support is located at the center of the bottom end of the woven bag.

[0007] As a further solution of the present invention: the number of the through holes corresponds to the number of the woven strips, and the woven strips are formed circumferentially and equidistantly on the outer periphery of the PE bag, and the through holes are formed circumferentially and equidistantly on the woven bag.

[0008] As a further solution of the present invention: the initial ends of the plurality of braided strips are fixedly connected to the outer wall of the PE bag by heat sealing.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. By setting the woven strips, bottom support and through holes, the bearing strength of the sandwich bag can be effectively improved, thereby improving the use quality of the bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figures 1 to 3 In an embodiment of the present invention, a sandwich composite woven bag includes a woven bag 1, a PE bag 2 is sleeved on the inner side of the woven bag 1, a plurality of strip-shaped woven strips 3 are integrally formed on the outer circumference of the PE bag 2, and through holes 5 are woven on the woven bag 1 for the woven strips 3 to pass through. The ends of the plurality of woven strips 3 are integrally formed with a bottom support 4, and the bottom support 4 is located at the bottom center of the woven bag 1.

[0017] In this embodiment: when making the woven bag 1 located on the outside, when using a machine to weave the woven bag 1, a through hole is formed by weaving, and then the PE bag 2 is made by blow molding, and the woven strips 3 and the bottom support 4 are woven by weaving, and finally the tops of the woven strips 3 are passed through the corresponding through holes 5 one by one, and fit with the outer wall of the PE bag 2, and then the tops of the woven strips 3 are heat-sealed to the outer wall of the PE bag 2 by heat sealing. After the heat sealing is completed, the top of the woven strips 3 (here the top is below the heat-sealed position) is connected to the woven bag 1 by sewing. After completing the above production, when the woven bag 1 is naturally vertical, the top of the bottom support 4 is in contact with the top of the woven bag 1;

[0018] The above-mentioned design method can improve the strength of the bag body, have better bearing capacity, and avoid the delamination and cracking of the woven bag 1 caused by carrying heavy grain.

[0019] Please refer to Figure 1 、 Figure 2 and Figure 3 The number of through holes 5 corresponds to the number of braided strips 3 , and the braided strips 3 are formed circumferentially and equidistantly on the outer periphery of the PE bag 2 , and the through holes 5 are formed circumferentially and equidistantly on the braided bag 1 .

[0020] In this embodiment, the through holes 5 should be formed by weaving rather than cutting, as cutting may damage the warp and weft of the woven bag 1 , thereby affecting product quality.

[0021] Please refer to Figure 1 The initial ends of the multiple braided strips 3 are fixedly connected to the outer wall of the PE bag 2 by heat sealing.

[0022] In this embodiment: since the woven bag 1 is made of plastic materials such as polyethylene and polypropylene, and the material of the PE bag is polyethylene, when the two are made of the same material, the heat-sealed connection has better connection strength, which can avoid the phenomenon of loose connection.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
