Description

Technical Field

[0001] The utility model relates to the technical field of ton bags, in particular to a center-sealed multi-layer packaging ton bag. Background Art

[0002] A ton bag is a flexible transport packaging container, which has the advantages of moisture-proof, dust-proof, radiation-resistant, firm and safe, and has sufficient structural strength. Because ton bags are easy to load and unload and carry, the loading and unloading efficiency is significantly improved. It has developed rapidly in recent years. Container bags are generally made of polyester fibers such as polypropylene and polyethylene.

[0003] At present, many factories use forklifts to move materials to designated areas or racks after storing them in ton bags. However, since ton bags usually contain a lot of materials, when the forklift lifts the handles on the ton bags, the handles on the bag body are easily broken due to excessive instantaneous pulling force, causing the ton bags to fall and the materials inside to spread.

[0004] Therefore, it is necessary to provide a new center-sealed multi-layer packaging ton bag to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a center-sealed multi-layer packaging ton bag.

[0006] The utility model provides a center-sealed multi-layer packaging ton bag comprising:

[0007] Bag body, and

[0008] An elastic airbag fixedly embedded in the bag body, and the elastic airbag covers the bottom of the bag body;

[0009] Arc-shaped hollow plates are fixedly embedded on both sides of the bag body, and a plurality of elastic air guide tubes connected with the elastic airbag are installed on the top of the arc-shaped hollow plate. An air injection component for injecting air into the elastic airbag and expanding the elastic airbag is arranged inside the arc-shaped hollow plate.

[0010] Preferably, the gas injection assembly includes an arc-shaped piston plate, which is slidably installed in an arc-shaped hollow plate, and two symmetrically distributed U-shaped rods are installed at the bottom of the arc-shaped piston plate, and one side connecting end of the U-shaped rod is fixedly installed at the bottom of the arc-shaped piston plate and passes through the bottom of the arc-shaped hollow plate.

[0011] Preferably, the gas injection assembly further comprises a connecting handle, and both ends of the connecting handle are respectively fixedly connected to the connecting ends of the two U-shaped rods located outside the arc-shaped hollow plate.

[0012] Preferably, a leather cover is fixedly embedded on the bottom of the elastic airbag.

[0013] Preferably, a woven layer is fixedly embedded in the bag body.

[0014] Preferably, the surface of the bag body is sprayed with RTV anti-fouling flashover coating.

[0015] Compared with the related art, the center-sealed multi-layer packaging ton bag provided by the utility model has the following beneficial effects:

[0016] 1. After the bag is filled with materials, the utility model uses a forklift to lift the connecting handles on both sides of the bag. As the forklift lifts the bag, the connecting handles pull up the U-shaped rod, so that the U-shaped rod drives the arc piston plate to slide along the arc hollow plate. Therefore, the gas in the arc hollow plate enters the elastic airbag through the elastic air guide tube and expands the elastic airbag. When the forklift lifts the bag in the initial stage, there is damping of the gas in the arc hollow plate, which avoids the hidden danger of the handles on the bag being broken due to excessive instantaneous pulling force after the bag is lifted by the forklift.

[0017] 2. When the forklift of the utility model places the bag body in the designated area, the elastic airbag at the bottom of the bag body is inflated at this time. As the bag body falls to the ground or the placement rack, the elastic airbag can buffer the bag body, thereby reducing the impact of the bag body on the ground or the placement rack.

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] See also Figure 1 to Figure 2The embodiment of the utility model provides a center-sealed multi-layer packaging ton bag, which includes: a bag body 1, an elastic airbag 2 and a curved hollow plate 3.

[0024] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The bag body 1 is provided with an elastic airbag 2, and the elastic airbag 2 is fixedly embedded in the bottom of the bag body 1 and covers the bottom of the bag body 1, and arc-shaped hollow plates 3 are fixedly embedded on both sides of the bag body 1, and a plurality of elastic air guide tubes 5 connected with the elastic airbag 2 are installed on the top of the arc-shaped hollow plate 3, and an air injection component 4 for injecting air into the elastic airbag 2 and expanding the elastic airbag 2 is arranged inside the arc-shaped hollow plate 3;

[0025] The gas injection assembly 4 includes an arc-shaped piston plate 41, which is slidably installed in the arc-shaped hollow plate 3, and two symmetrically distributed U-shaped rods 42 are installed at the bottom of the arc-shaped piston plate 41. One side connecting end of the U-shaped rod 42 is fixedly installed at the bottom of the arc-shaped piston plate 41 and passes through the bottom of the arc-shaped hollow plate 3, and the gas injection assembly 4 also includes a connecting handle 43, and the two ends of the connecting handle 43 are respectively fixedly connected to the connecting ends of the two U-shaped rods 42 located on the outside of the arc-shaped hollow plate 3.

[0026] It should be noted that: after the material in the bag body 1 is bagged, the connecting handles 43 on both sides of the bag body 1 are lifted by a forklift. As the bag body 1 is lifted by the forklift, the connecting handles 43 pull up the U-shaped rod 42, so that the U-shaped rod 42 drives the arc-shaped piston plate 41 to slide up along the arc-shaped hollow plate 3, so that the gas in the arc-shaped hollow plate 3 enters the elastic airbag 2 through the elastic air guide tube 5 and causes the elastic airbag 2 to expand;

[0027] When the forklift lifts the bag body 1 in the initial stage, the gas in the arc hollow plate 3 provides damping, thereby avoiding the hidden danger of the handle on the bag body 1 breaking due to excessive instantaneous tension after the bag body 1 is lifted by the forklift. When the forklift places the bag body 1 in the designated area, the elastic airbag 2 at the bottom of the bag body 1 is inflated at this time. As the bag body 1 falls to the ground or the placement rack, the elastic airbag 2 can buffer the bag body 1, thereby reducing the impact of the bag body 1 on the ground or the placement rack.

[0028] Among them, a leather cover 21 is fixedly embedded in the bottom of the elastic airbag 2, which improves the wear resistance of the elastic airbag 2, and a woven layer 11 is fixedly embedded in the bag body 1, which improves the tensile resistance of the ton bag. The surface of the bag body 1 is sprayed with RTV anti-pollution flashover paint, which effectively reduces the sewage on the outer surface of the bag body 1 from penetrating through the bag body 1 and causing pollution to the materials inside the bag body 1.

[0029] The working principle of the center-sealed multi-layer packaging ton bag provided by the utility model is as follows:

[0030] After the material in the bag body 1 is bagged, the connecting handles 43 on both sides of the bag body 1 are lifted by a forklift. As the bag body 1 is lifted by the forklift, the connecting handles 43 pull up the U-shaped rod 42, so that the U-shaped rod 42 drives the arc piston plate 41 to slide up along the arc hollow plate 3, so that the gas in the arc hollow plate 3 enters the elastic airbag 2 through the elastic air guide tube 5 and causes the elastic airbag 2 to expand;

[0031] In the initial stage when the forklift lifts the bag body 1, the gas in the arc hollow plate 3 provides damping, thereby avoiding the hidden danger of the handle on the bag body 1 breaking due to excessive instantaneous pulling force after the bag body 1 is lifted by the forklift. When the forklift places the bag body 1 in the designated area, the elastic airbag 2 at the bottom of the bag body 1 is inflated at this time. As the bag body 1 falls to the ground or the placement rack, the elastic airbag 2 can buffer the bag body 1, thereby reducing the impact of the bag body 1 on the ground or the placement rack.

[0032] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0033] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
