[0002] A bulk bag is a flexible transport packaging container with the advantages of being moisture-proof, dust-proof, radiation-resistant, firm and safe, and has sufficient structural strength. Since bulk bags are easy to load and unload and carry, the loading and unloading efficiency has been significantly improved. They have developed rapidly in recent years. Bulk bags are generally made of polyester fibers such as polypropylene and polyethylene. They can be widely used in the packaging of various powdery, granular and blocky items such as chemicals, building materials, plastics, and minerals. They are ideal products for warehousing, transportation and other industries. Bulk bags are mainly composed of outer bags, inner bags, slings, and inlets and outlets.

[0003] The inner bag of a container bag is usually a bag that cooperates with the main body of the container bag to further enhance the sealing protection of the material contained, prevent the material from leaking, getting damp, getting contaminated, etc.; it can better maintain the purity and quality stability of the material; it is used in some situations where higher protection requirements are required, such as when there are special needs for moisture-proofing and anti-volatile properties.

DETAILED DESCRIPTION

[0023] See also Figure 1-5The utility model provides a technical solution: a reinforced container bag with an inner bag top, comprising an outer bag body 1 and a protective device 6, an outer bag body 1 is arranged inside the outer bag body 1, a feed port 3 is arranged on the upper surface of the inner bag body 2, and a discharge port 4 is arranged on the lower surfaces of the inner bag body 2 and the outer bag body 1, and four sling parts 5 are arranged on the surface of the outer bag body 1.

[0024] The specific configuration and function of the protection device 6 and the auxiliary mechanism 65 will be described in detail below.

[0025] Specifically, the protective device 6 includes a clamping belt 1 61 and a clamping belt 2 62. The clamping belt 1 61 and the clamping belt 2 62 are respectively fixed on the two side surfaces of the feed port 3 above the inner bag body 2. The surface of the clamping belt 1 61 is provided with a perforation for the clamping belt 2 62 to pass through. A pulling assembly 64 is provided between each of the four slings 5. Two drawstrings 63 are fixedly connected to the surfaces of the clamping belt 1 61 and the clamping belt 2 62. The four drawstrings 63 are respectively fixedly connected to the pulling assembly 64 in pairs. An auxiliary mechanism 65 is provided on the surface of the outer bag body 1.

[0026] In this embodiment: when the outer bag body 1 is lifted by the sling part 5, the lifting component 64 can be driven to move at the same time. The lifting component 64 cooperates with the pull rope 63 to pull the clamping belt 1 61 and the clamping belt 2 62 respectively, clamping and reinforcing the two pairs of discharge ports 4, thereby improving the stability effect, improving the sealing performance of the bag mouth, reducing the risk of material leakage, and thereby improving the overall stability of the equipment.

[0027] Specifically, four guide belts 66 are fixedly connected to the upper surface of the outer bag body 1, and the four guide belts 66 are for the drawstring 63 to pass through. When the drawstring 63 pulls the clamping belt 1 61 and the clamping belt 2 62, the guide belts 66 can guide the drawstring 63.

[0028] Specifically, the lifting assembly 64 includes a belt body 641, which is slidably connected to the inner wall of the sling part 5, and a control rope 644 is fixedly connected to the corresponding side of the two belt bodies 641, and one end of the pull rope 63 is fixedly connected to the surface of the control rope 644.

[0029] In this embodiment, when lifting, the object inserted into the sling part 5 can be inserted into the sleeve 643 for lifting, and the belt body 641 can cooperate with the control rope 644 to pull the drawstring 63 to complete the use.

[0030] Specifically, both ends of the belt body 641 are fixedly connected with intercepting members 642 , and the intercepting members 642 are cylindrical.

[0031] In this embodiment, the intercepting member 642 can guide and intercept the belt body 641 .

[0032] Specifically, four positioning rods 67 are fixedly connected to the surface of the clamping belt 2 62. The four positioning rods 67 are fixedly connected to the two sides of the clamping belt 2 62 in pairs. The positioning rods 67 can prevent the clamping belt 2 62 from moving out of the perforations on the surface of the clamping belt 1 61, thereby playing a positioning role.

[0033] Specifically, the auxiliary mechanism 65 includes a pressing belt 651, and there are two pressing belts 651. The two pressing belts 651 are fixedly connected to the surface of the outer bag body 1. The other side surface of the outer bag body 1 is fixedly connected to a limiting belt 654. The surfaces of the pressing belts 651 are respectively fixedly connected with Velcro 1 652 and Velcro 2 653.

[0034] In this embodiment, after the pressing belt 651 passes through the limiting belt 654, the pressing belt 651 is tightened, and then the Velcro 1 652 is pasted on the Velcro 2 653 to perform auxiliary reinforcement.

[0035] Working principle: By setting the protection device 6 and the auxiliary mechanism 65, when lifting, the object inserted into the sling part 5 can be inserted into the sleeve 643 for lifting. When lifting, the sleeve 643 drives the belt body 641 to slide in the sling part 5, and the intercepting member 642 is limited. The belt body 641 can cooperate with the control rope 644 to pull the drawstring 63, and the drawstring 63 moves in the guide belt 66. The four drawstrings 63 pull the clamping belt 1 61 and the clamping belt 2 62 in pairs, so that the clamping belt 1 61 and the clamping belt 2 62 are deformed. The feed port 3 is clamped, and then the pressure belt 651 is passed through the limiting belt 654. After the pressure belt 651 is tightened, the Velcro 1 652 is pasted on the Velcro 2 653 to perform auxiliary reinforcement, and the discharge port 4 is clamped and reinforced from the two pairs. By setting the protective device 6, it can effectively reduce the existing container bag after being lifted after loading. Since the upper material port of the inner bag of the container belt is tightened by manual bundling, the bundling is tightened inconsistently, and the bundling is prone to looseness, which causes material leakage.
