Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ton bags, in particular to a ton bag capable of无损inverting the bag. Background Art
[0002] During the production process of the aluminum industry, the aluminum ash residue generated is packed and transported in ton bags. The aluminum ash residue needs to be harmlessly treated and then highly utilized. The treatment process is as follows: The aluminum ash residue to be treated is盛装in a ton bag. It is lifted by a crane to above the inlet of the treatment equipment. Workers need to go under the ton bag and use a knife to cut open the bottom of the ton bag so that the aluminum ash residue is unloaded from the bottom into the inlet.
[0003] In the above treatment process, since the ton bag needs to be manually cut open, the worker is relatively close to the ton bag. The dust generated during the unloading of the aluminum ash residue is extremely likely to affect the worker. The working environment is poor, and there are health risks and safety hazards. Moreover, the ton bag is damaged and scrapped after being cut open and cannot be reused, which greatly increases the production cost. Summary of the Invention
[0004] In order to solve the problem that the conventional operation of破吨包to unload the material will bring risks to workers and the ton bag cannot be reused, the utility model provides a ton bag capable of无损inverting the bag. By optimizing the structure of the ton bag, lifting points are arranged on its upper and lower parts respectively. The main and auxiliary hooks of the crane are respectively hooked on the upper and lower two lifting points, so that the ton bag filled with aluminum ash residue can be overturned, realizing the automatic lifting and automatic unloading operation of the ton bag, and the ton bag can be reused repeatedly.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A ton bag capable of无损inverting the bag includes a ton bag body, suspension straps and a surrounding belt. The upper end of the ton bag body is open and the lower end is closed, which is convenient for盛装aluminum ash residue. Two suspension straps are sewn on the ton bag body, which is convenient for lifting and moving the ton bag. Each suspension strap is bent into a "凵" shape and wound around the two sides and the bottom of the ton bag body, improving the connection area between the suspension strap and the ton bag body;
[0007] The suspension straps located on both sides of the ton bag body are side sections. The side section of each suspension strap extends upward and越过the bag mouth of the ton bag body. The upper ends of the side sections are connected pairwise to form an inverted U-shaped upper hook hanging section, which is convenient for the main hook of the crane to hook. The surrounding belt is sewn on the periphery of the ton bag body and wound between the side sections, improving the connection stability between the suspension strap and the ton bag body;
[0008] It should be noted that the Chinese expression "无损" in the original text seems incorrect. It might be a misspelling. I translated it as "无损" as it was in the original text, but it should probably be something like "无损地" or a more appropriate term depending on the actual meaning. Also, "盛装" should likely be "盛装于" for more accurate grammar. You may want to double-check the original Chinese text for accuracy.The suspension straps located at the bottom of the bulk bag body are the bottom sections. The bottom sections of the two suspension straps are arranged in a cross shape, and a lower hook section is reserved in the middle of the bottom sections. The lower hook section is not sewn and connected to the bottom surface of the bulk bag body. There is a gap between the bottom of the bulk bag body and the lower hook section, facilitating the insertion of the auxiliary hook of the crane. The lower hook sections of the two suspension straps overlap, and the overlapping position is at the center of the bottom of the bulk bag body. The overlapping parts of the lower hook sections of the two suspension straps are sewn and connected to ensure firm and reliable connection.
[0009] Furthermore, both the suspension straps and the surrounding straps are strip-shaped bodies with a certain width. The two suspension straps are arranged in a cross shape, and the two suspension straps are evenly arranged on the bulk bag body to ensure uniform stress on the bulk bag body during lifting.
[0010] Furthermore, the side section of each suspension strap extends upward越过 the bag mouth of the bulk bag body and then continues to extend upward, and then bends downward to extend to the bag mouth position of the bulk bag body. The side section of the suspension strap first extends upward and then bends downward, forming a winding trajectory近似于 “卩” 字形.
[0011] Furthermore, after the end of the side section winds downward, it overlaps with the side sections on both sides of the bulk bag body. The surrounding strap covers the end of the side section and is sewn and connected to the end of the side section. The surrounding strap can enclose the end of the side section, the side section, and the bulk bag body, and the overlapping positions of the above three are sewn and connected.
[0012] Furthermore, the upward and downward extending parts of the side sections of the two suspension straps overlap and are sewn and connected. The upper hook section is a double-layer strip-shaped body structure formed by sewing the two overlapping side sections, increasing the structural strength of the upper hook section itself and improving the stress effect.
[0013] Furthermore, the sum of the lengths of the bottom section and the lower hook section is greater than the diameter of the bottom of the bulk bag body to ensure there is a large enough gap between the lower hook section and the bottom surface of the bulk bag body;
[0014] A reinforcing ring is also sewn between the lower hook section of each suspension strap and the bottom of the bulk bag body. The reinforcing ring is a flat ring body formed by winding and sewing a strip-shaped body, which increases the connection area between the lower hook section and the bulk bag body, equivalent to a structure where the lower hook section is also sewn by a double-layer strip-shaped body.
[0015] Through the above technical solutions, the beneficial effects of the present utility model are:
[0016] The structure of the present utility model is reasonably designed. Conventional bulk bags cannot be flipped using a crane and can only be lifted. By optimizing the structure of the bulk bag, two suspension straps arranged in a cross shape are evenly sewn on the bulk bag body. The suspension straps are arranged in a “凵” shape around the three-week sides of the bulk bag body, which can increase the contact area with the bulk bag body and ensure firm connection.
[0017] The two ends of the sling of the utility model extend upward, bend and extend downward, and at the same time, the upper ends of the two slings overlap to form an upper hook hanging section. The upper hook hanging section is equivalent to a double-layer belt body sewn together, which has high strength and can effectively bear force to prevent breakage. At the same time, the bottom of the ton bag body has two lower hook hanging sections. The lower hook hanging sections are not sewn with the ton bag body, but there is a gap between the two, which allows the auxiliary hook of the driving to pass through and hook the lower hook hanging section. At the same time, a reinforcement ring is used to increase the contact area between the lower hook hanging section and the ton bag body, thereby improving the structural strength.
[0018] The utility model can vertically lift the ton bag body by hanging the upper hook section through the main hook of the crane, and can tip the ton bag body so that its opening faces downward by hanging the lower hook section through the auxiliary hook of the crane, so that the materials in the ton bag body can be dumped fully and efficiently, and the conventional destructive operation of manually cutting the ton bag can be avoided. Workers can stay away from the ton bag to operate the tipping and unloading, thereby ensuring the safety of the workers, and the ton bag can be reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:
[0027] like Figure 1 to Figure 6As shown, a bulk bag capable of lossless reverse packaging includes a bulk bag main body 1, suspension straps 2, and a surrounding strap 3. The upper end of the bulk bag main body 1 is open, and the lower end is closed, and it can be used to contain materials. Here, the bulk bag main body 1 can be cylindrical. Two suspension straps 2 are sewn on the bulk bag main body 1, and the suspension straps 2 are used for lifting the bulk bag main body 1, as Figure 1 shown.
[0028] The two suspension straps 2 are arranged in a cross shape, and the two suspension straps 2 are evenly arranged on the bulk bag main body 1. Each suspension strap 2 is bent into a "凵" shape and wound around both sides and the bottom of the bulk bag main body 1, so as to evenly wrap the bulk bag main body 1 and increase the connection area between the suspension strap 2 and the bulk bag main body 1.
[0029] The suspension straps 2 located on both sides of the bulk bag main body 1 are side segments 21. One suspension strap 2 has two side segments 21, and the side segments 21 are sewn to the side surface of the bulk bag main body 1. The side segments 21 of each suspension strap 2 extend vertically upward and cross over the bag mouth of the bulk bag main body 1. Between the upper ends of the side segments 21, two by two are connected to form an inverted U-shaped upper hook hanging section 4. The two suspension straps 2 have four side segments 21, and the four side segments 21 are sewn and connected two by two to form two upper hook hanging sections 4. The upper hook hanging section 4 is used for hooking and connecting with the main hook of the traveling crane.
[0030] In order to increase the structural strength of the upper hook hanging section 4, the side segments 21 of each suspension strap 2 continue to extend upward after crossing over the bag mouth of the bulk bag main body 1 and then bend downward and extend to the bag mouth position of the bulk bag main body 1. Specifically, one side segment 21 of one suspension strap 2 continues to extend upward and then bends and extends backward and downward. The extended end point position is as Figure 2 point A shown in. One side segment 21 of the other suspension strap 2 continues to extend upward and then bends and extends forward and downward. The extended end point position is as Figure 2 point B shown in.
[0031] Referring to the bending method of the suspension strap 2 described above, the two side segments 21 of the other suspension strap 2 extend forward and downward and backward and downward respectively. The extended end point positions are as Figure 2 points C and D shown in. The above extended end points are also the two end points of the suspension strap 2. That is, one suspension strap 2 is composed of the strap body between points A and B, and the other suspension strap 2 is composed of the strap body between points C and D.
[0032] In this way, the upward and downward extended portions of the side segments 21 of the two suspension straps 2 are arranged overlappingly and sewn together, and the overlapping portion is bent into an inverted U shape. Therefore, the upper hook hanging section 4 is a double-layer strap body structure sewn from two overlapping side segments 21, which can improve the strength of the upper hook hanging section 4, as Figure 3 and Figure 4 shown.
[0033] At the same time, after the end of the side section 21 is wound downward, it overlaps with the side sections 21 on both sides of the ton bag body 1, that is, after the end of the side section 21 extends downward to the bag opening of the ton bag body 1, it continues to extend downward, covers the side section 21, and is sewn to the side section 21. In this way, the sewing connection between the end of the sling 2 and the ton bag body 1, and between the end of the sling 2 and the belt body of another sling 2 can be achieved, ensuring the reliability of the connection between the sling 2 and the ton bag body 1.
[0034] The sling 2 and the belt 3 are both belts with a certain width. The belt 3 is sewn around the ton bag body 1. The belt 3 is arranged around the ton bag body 1 in a circle, and the belt 3 is arranged between the side sections 21 and is sewn and connected to the side sections 21. Since the end of the side section 21 extends downward over the bag opening of the ton bag body 1, the belt 3 covers the end of the side section 21 and is sewn and connected to the end of the side section 21 to prevent the end of the side section 21 from falling off due to force.
[0035] The sling 2 at the bottom of the ton bag body 1 is the bottom section 22. One sling 2 has one bottom section 22, and the bottom section 22 is sewn to the bottom surface of the ton bag body 1. The bottom sections 22 of the two slings 2 are arranged in a cross shape, and a lower hook section 5 is reserved in the middle of the bottom section 22, but the lower hook section 5 is not sewn together with the ton bag body 1. The lower hook section 5 is in a loose state relative to the bottom section 22. At the same time, the sum of the lengths of the bottom section 22 and the lower hook section 5 is greater than the diameter of the bottom of the ton bag body 1. In this way, there is a gap between the bottom of the ton bag body 1 and the lower hook section 5, which can accommodate the auxiliary hook of the driving vehicle to pass through and hook the lower hook section 5.
[0036] The lower hook sections 5 of the two slings 2 overlap, and the overlapping position is located at the bottom center of the ton bag body 1. The overlapping parts of the lower hook sections 5 of the two slings 2 are sewn and connected to ensure the connection strength of the two lower hook sections 5. Figure 5 The dotted line area in the box indicates the overlapping position between the lower hooking segments 5 .
[0037] In order to increase the connection strength of the lower hook section 5, a reinforcement ring 6 is sewn between the lower hook section 5 of each sling 2 and the bottom of the ton bag body 1. The reinforcement ring 6 is a flat ring body formed by winding and sewing the belt body. The two sides of the reinforcement ring 6 are respectively sewn together with the bottom surface of the ton bag body 1 and the lower hook section 5, which increases the connection area between the lower hook section 5 and the ton bag body 1. In this way, the lower hook section 5 is also equivalent to a double-layer belt structure. Figure 6 shown.
[0038] The principle of the utility model is: two cross-shaped slings 2 are tightly sewn on the ton bag body 1, and the surrounding belt 3 is sewn around the ton bag body 1 to ensure that the slings 2, the surrounding belt 3 and the ton bag body 1 are firmly connected. A certain gap is left between the cross-section of the slings 2 and the bottom surface of the ton bag body 1 to ensure that the auxiliary hook of the driving can penetrate.
[0039] The ton bag is used to hold aluminum ash slag. When the aluminum ash slag needs to be processed, the main hook of the crane is used to hook the two upper hook sections 4, so as to lift the ton bag to the top of the inlet of the processing equipment. Then the auxiliary hook of the crane is used to hook the two lower hook sections 5, and then the ton bag is steadily lowered to the inlet, and the main hook of the crane is operated to separate from the upper hook section 4. Then the auxiliary hook of the crane is steadily raised, so that the ton bag gradually dumps, and then the bottom of the ton bag faces upward and the open end faces downward, and then the aluminum ash slag is steadily poured into the inlet of the processing equipment. After the aluminum ash slag is dumped clean, the ton bag is removed, folded neatly, and stored in a dry and dark place for next use.
[0040] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
