Description

Technical Field

[0001] This utility model relates to the field of ton bags, and in particular to a leak-proof ton bag. Background Technology

[0002] Ton bags, also known as bulk containers or flexible container bags, are flexible packaging containers designed specifically for bulk materials. Their core feature is that they can bear the weight of 1 ton or more of materials, and they also have the functions of convenient transportation and storage. They are widely used in industries such as chemical, food, building materials, and mining. The ton bag body mostly adopts a single-layer or simple double-layer structure. The seams rely on traditional sewing technology, and needle holes are prone to forming leakage channels. The leakage problem is particularly prominent when dealing with fine dust or low-viscosity liquid materials. The bag mouth seal is mostly a single rope tie or simple cap design. It is prone to seal failure due to vibration and compression during transportation. The bottom unloading structure is mostly a fixed opening type, which makes it difficult to achieve secondary sealing after unloading. Residual materials are prone to leakage, and the bag body has poor reusability. Moreover, the ton bag needs to be lifted to expose the unloading port before unloading can be carried out, which is physically demanding. Therefore, we propose a leak-proof ton bag. Utility Model Content

[0003] The main purpose of this utility model is to provide a leak-proof ton bag, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A leak-proof ton bag includes a ton bag body, a feeding structure embedded in the upper surface of the ton bag body, two sets of lifting straps fixedly installed on the front and rear surfaces of the ton bag body, and a discharging structure embedded in one side surface of the ton bag body.

[0005] Furthermore, the ton bag body includes a thickened layer, a connecting layer, an outer shell, a PP woven fabric layer, a tensile reinforcement layer, and a PE sealing film layer.

A feeding structure 3 is embedded in one side surface of the ton bag body 2. Specifically, the ton bag body 2 is moved by the lifting strap 1, the ton bag body 2 is fed by the feeding structure 4, and the material inside the ton bag body 2 is discharged by the discharging structure 3.

[0015] In a preferred embodiment, the ton bag body 2 includes a thickening layer 201, a connecting layer 202, an outer shell 203, a PP woven fabric layer 204, a tensile reinforcement layer 205, and a PE sealing film layer 206. The thickening layer 201 is embedded and installed on the inner surface of the outer shell 203 at the bottom, and the connecting layer 202 is fixedly installed on the upper surface of the thickening layer 201 at the edge. The thickening layer 201 is provided with the PP woven fabric layer 204, the tensile reinforcement layer 205, and the PE sealing film layer 206 in sequence from the outside to the inside. Specifically, the material is filled through the outer shell 203. The bottom of the outer shell 203 is reinforced by the thickened layer 201. The connecting layer 202 connects the thickened layer 201 and the outer shell 203. The outer shell 203 is U-shaped, which encloses the feeding structure 4, making it easy to carry and preventing the feeding structure 4 from being damaged by collision. The PE sealing film layer 206 is spliced ​​by heat sealing process, without needle-hole seams. The tensile strengthening layer 205 is a glass fiber woven layer, which is fixed together with the PE sealing film layer 206 and the PP woven fabric layer 204 by hot melt adhesive to improve the overall tensile strength of the bag.

[0016] In a preferred embodiment, the feeding structure 4 includes a threaded cap 401 and a threaded tube 402, with the threaded cap 401 sleeved on the surface of the threaded tube 402; Specifically, the threaded tube 402 is sealed by fitting the threaded cap 401 over the threaded tube 402, and the threaded cap 401 has a sealing gasket inside.

[0017] In a preferred embodiment, the threaded tube 402 is embedded in the upper surface of the housing 203 at the middle position, and the carrying strap 1 is fixedly installed on the front and rear surfaces of the housing 203 respectively. Specifically, by embedding the threaded tube 402 into the outer shell 203, the material enters the interior of the outer shell 203 through the threaded tube 402, and the lifting strap 1 is fixed to the surface of the outer shell 203 to facilitate the movement of the outer shell 203.

[0018] In a preferred embodiment, the feeding structure 3 includes a cover 301, a first discharge pipe 302, a second discharge pipe 303, a threaded rod 304, a nut 305, a mounting plate 306, a fixing plate 307, a slider 308, and a groove 309. The fixing plate 307 is fixedly installed on one side of the surface of the first discharge pipe 302, and the threaded rod 304 is fixedly installed on one side of the fixing plate 307. The slider 308 is fixedly installed on the other side of the surface of the first discharge pipe 302. There are two sets of sliders 308. The second discharge pipe 303 is sleeved on the surface of the first discharge pipe 302. The inner surface of the second discharge pipe 303 is provided with a groove 309. There are two sets of grooves 309. The sliders 308 are respectively embedded in the inside of the grooves 309. The cover 301 is sleeved on one side of the surface of the second discharge pipe 303, and the mounting plate 306 is fixedly installed on the other side of the surface of the second discharge pipe 303. The nut 305 is sleeved on the surface of the threaded rod 304. Specifically, by loosening the nut 305 and pulling the second discharge pipe 303 to one side, the slide groove 309 and the slider 308 slide together, and the mounting plate 306 moves away from the threaded rod 304. This causes the second discharge pipe 303 to move on the surface of the first discharge pipe 302, thereby extending the first discharge pipe 302. The cavity for receiving materials is placed below the second discharge pipe 303, thereby increasing the discharge space and preventing spillage. At this time, the cap 301 can be unscrewed to allow material to be discharged. The inner surface of the cap 301 and the outer surface of the second discharge pipe 303 are threaded, and the inside of the cap 301 is equipped with a sealing gasket. The mounting plate 306 has a through hole, and the threaded rod 304 is embedded in the through hole. Therefore, under the action of the threaded rod 304 and the nut 305, the positions of the second discharge pipe 303 and the first discharge pipe 302 remain stable, preventing loosening.

[0019] In a preferred embodiment, the first discharge pipe 302 is embedded in one side surface of the housing 203 at the lower position; Specifically, by embedding the first discharge pipe 302 on one side of the outer casing 203, the material inside the outer casing 203 is discharged through the first discharge pipe 302.

[0020] It should be noted that during use, the material is filled into the interior of the outer casing 203 through the threaded tube 402 and the threaded cap 401 is tightened. When it is necessary to unload the material, the nut 305 can be loosened first, and the second discharge tube 303 can be pulled to one side to extend the first discharge tube 302. The cap 301 can be unscrewed from the second discharge tube 303 to unload the material. After unloading, the second discharge tube 303 can be pushed back so that the mounting plate 306 is close to the fixing plate 307. The nut 305 can be tightened again, and the cap 301 can be put on the second discharge tube 303.

[0021] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
