Description

Technical Field

[0001] This utility model relates to the field of container bag technology, and in particular to an M-fold container bag with a feeding port. Background Technology

[0002] FIBCs (Flexible Intermediate Bulk Containers) are flexible transport packaging containers widely used for transporting powdery, granular, and lumpy goods such as food, grains, pharmaceuticals, chemicals, and minerals. They are characterized by their low price, robustness, reliability, and moisture and sun protection.

[0003] Existing FIBCs (Flexible Intermediate Bulk Containers) consist of a saddle and lifting straps, involving numerous processing steps. The lifting straps are manually sewn onto the FIBC at the later stage, leading to insufficient strap strength. During lifting, uneven force can easily cause the lifting area to tear from the side pockets, resulting in structural damage and spillage of contents, impacting work efficiency. Furthermore, during use, material leakage is prone to occur at the sewn areas. The stitch spacing and quality of the seams are inconsistent and unreliable due to manual labor, and sealing performance is also compromised. Moreover, automated production is difficult, requiring a large amount of manual labor. Additionally, the existing bottom outlet structure is relatively simple and not conducive to proper sealing.

[0004] Developing M-fold FIBCs with feed openings and their production processes, extensively utilizing mechanized production to reduce manual labor, and integrating the lifting straps with the FIBC to improve its strength, while reducing the area of ​​sewn parts to enhance its sealing performance, improving the bottom structure, and reducing feed opening leakage have become pressing technical challenges for those skilled in the art.

[0005] The purpose of this invention is to provide an M-fold container bag with a feeding port to solve the problems listed in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model relates to an M-fold container bag with a feeding port, comprising a bag body, a lifting strap, and a feeding port. The upper end of the bag body is integrally formed with the lower end of the lifting strap and the lower opening of the feeding port.

[0008] The upper opening of the sling assembly is fixedly connected via a stitched area;

[0009] The vertical joint of the feed inlet is fixedly connected by a hot-press welding zone;

[0010] The lower opening of the bag body is fixedly connected to the bottom of the bag through the stitching area;

[0011] A discharge port unit is installed in the middle of the bottom of the bag.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] This utility model relates to an M-fold container bag with a discharge port. The lifting straps are integrally formed with the bag body, reducing the processing steps when sewing the lifting straps onto the bag body later, reducing needle holes on the bag body, and ensuring the sealing performance of the bag body. At the same time, the lifting straps and the bag body are made of the same material, which effectively ensures the connection strength between the lifting straps and the bag body. Furthermore, the connection between the lifting straps and the discharge port, which does not bear tensile force, is connected by a heat-sealing area, ensuring the sealing performance of the M-fold container bag with a discharge port. The connection between the lifting straps and the sealing area between the bag body and the bottom of the bag are connected by a stitched area, ensuring the stability of the connection in the stress area. The combination of heat-sealing and stitched areas accelerates the processing speed of the container bag, reduces the amount of manual labor, and ensures the uniformity and stability of the container bag after processing, which is conducive to mechanized and automated production. At the same time, the discharge port unit is fixedly connected to the bottom of the bag to facilitate the unloading of the container bag, and the design of the anti-leakage ring ensures the sealing performance of the discharge port and prevents material from leaking from the bottom of the container bag.

[0025] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 1-6 As shown, the bag includes a bag body 1, a lifting strap 2, and a feeding port 4. The upper end of the bag body 1 is integrally formed with the lower end of the lifting strap 2 and the lower opening of the feeding port 4, which effectively ensures the connection strength between the lifting strap and the bag body. On the one hand, it eliminates the need to sew the lifting strap on the outside of the bag body, reducing the risk of powder material leaking from the stitches. On the other hand, it reduces the sewing process and the amount of labor required, thus reducing production and manufacturing costs.

[0027] The upper opening of the sling body 2 is fixedly connected by the stitching area 3. The stitching area effectively ensures the firmness of the connection between the sling bodies and avoids the risk of falling during the lifting of materials.

[0028] The vertical joint of the feed inlet 4 is fixedly connected by the hot-press welding area 5, which reduces the stitches left during the sewing process. The hot-press welding connection ensures the sealing performance of the material during the filling process through the feed inlet.

[0029] The lower opening of the bag body 1 is fixedly connected to the bag bottom 7 through the stitching area 3. The stitching area is used to connect the stress area of ​​the bag bottom, which effectively ensures the stability of the bag bottom connection.

[0030] A discharge port unit 6 is installed in the middle of the bottom of the bag 7.

[0031] Specifically, the bottom 7 of the bag is made of the same material as the body 1 of the bag, and the bottom 7 of the bag is square in shape, which can improve the space utilization rate of the container bag during storage and transportation. At the same time, it can adapt to the working state of the bag body and avoid material leakage caused by the bottom of the bag being pulled by the bag body due to the inconsistency between the bottom and the body of the bag after being filled with materials.

[0032] Specifically, the feeding port unit 6 includes a feeding tube and a leak-proof ring, and the upper opening of the feeding tube is fixedly connected to the opening in the middle of the bag bottom 7 through the sewing area 3;

[0033] The outer edge of the leak-proof ring is fixedly installed on the lower surface of the bag bottom 7 through the stitching area 3;

[0034] The leak-proof ring is coaxial with the feed pipe, and the inner diameter of the leak-proof ring is larger than the outer diameter of the feed pipe. When filling materials, the opening of the feed pipe is tied and placed inside the leak-proof ring, and the opening of the feed pipe is sealed under the gravity of the materials.

[0035] Furthermore, a baffle plate is installed on the inner side wall of the leak-proof ring. The size of the baffle plate is larger than the size of the inner ring of the leak-proof ring. The baffle plate can seal the inner ring of the leak-proof ring to prevent the discharge pipe from coming out of the leak-proof ring during hoisting.

[0036] It also includes a fastening rope loop, which is fixedly installed on the inner ring of the leak-proof ring through the seam area 3. The fastening rope loop can tighten the inner ring opening to prevent the material from falling out of the leak-proof ring during hoisting and can ensure the effectiveness of the baffle sealing process.
