Description

Technical Field

[0001] This utility model relates to the field of ton bags and ton bag packaging technology, and in particular to a ton bag packaging device and a ton bag. Background Technology

[0002] FIBCs, also known as bulk containers, flexible transport bags, or ton bags / bags / bag bags / space bags / mother-daughter bags, are a type of flexible transport packaging container. They offer advantages such as moisture resistance, dust resistance, radiation resistance, and robust safety, while also possessing sufficient structural strength. Due to their ease of loading, unloading, and handling, FIBCs have significantly improved efficiency and have experienced rapid development in recent years. FIBCs are generally made of polyester fibers such as polypropylene and polyethylene. They are suitable for transporting large quantities of bulk powdery materials, featuring large volume, light weight, and ease of loading and unloading, making them a common packaging material. Their characteristics include simple structure, light weight, foldability, small space occupation when empty, and low price.

[0003] Ton bags require a ton bag packaging machine for material loading. The ton bag packaging machine is a multi-purpose device integrating electronic weighing, automatic bag removal, and dust removal. It boasts a high degree of automation, high packaging precision, adjustable packaging speed, and superior structure, making it suitable for packaging materials in various industries.

The ton bag lifting mechanism includes a ton bag lifting frame, lifting cylinders are installed at the four corners of the ton bag lifting frame, the cylinder body of the lifting cylinder is fixed to the left cylinder mounting plate and the right cylinder mounting plate, the piston rod of the lifting cylinder is rotatably connected to the top of the grab hook, and the middle part of the grab hook is rotatably connected to the left cylinder mounting plate and the right cylinder mounting plate. This utility model can ensure the stability of the ton bag lifting process and can achieve convenient and quick unloading of the ton bags.

[0005] However, existing equipment and the aforementioned ton bag packaging machines all have a problem: the ton bags themselves are made of flexible material, which can cause various bends at the top opening. Even when hung on hooks with lugs, the top edge of the bag opening may still tilt inward, resulting in the top opening not being aligned with the upper discharge port. Therefore, manual inspection and straightening are required, which undoubtedly reduces production efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a ton bag packaging device and a ton bag, which solves the problem that in existing technologies, the ton bag is a flexible structure, which may cause the top edge to bend inward after being hung, blocking the feed inlet, thus requiring manual inspection and handling, resulting in reduced efficiency.

[0007] In a first aspect, this utility model proposes a ton bag packaging device, including a support frame, a weighing platform disposed in the middle of the support frame, and a guide rail disposed on the upper part of the support frame. The support frame includes a base and a support rod disposed on the base. An mounting plate is disposed on the top of the support rod, and a feeding funnel is disposed in the middle of the mounting plate. The weighing platform is installed in the middle of the base. Several baffles are disposed around the edge of the weighing platform. The spacing between the baffles is matched with the size of the ton bag. An electromagnet is disposed on the side of the baffles near the center of the weighing platform.

[0008] The guide rail is located in the area between the bottom of the feed hopper and the top of the baffle. The guide rail is horizontally positioned, with one end extending directly above the weighing platform. The portion above the weighing platform does not obstruct the space below the feed hopper. A trolley is also slidably mounted on the bottom of the guide rail, and several hooks are mounted on the bottom of the trolley.

[0009] Furthermore, the weighing platform is a square plate structure, and there are four baffles, which are vertically installed at the four corners of the weighing platform.

[0010] Furthermore, the guide rail includes two horizontally parallel rails, and the trolley is slidably connected to both rails simultaneously.

[0011] Furthermore, the trolley is a horizontally arranged directional frame structure, and the size of the hollow area in the middle of the trolley is matched with the size of the weighing platform. There are four hooks in total, which are respectively set at the four corners of the bottom of the trolley.

[0012] Furthermore, the electromagnets installed on the stop lever are divided into multiple independently arranged sequentially along the vertical direction.

[0013] Secondly, this utility model also proposes a ton bag, which is a hollow cubic structure with four hanging ears at the four corners of the ton bag. The four vertical edges of the ton bag have vertical strip-shaped filling areas inside, and magnetic filler is embedded in the filling areas. The magnetic filler has a granular structure and does not affect the folding performance of the ton bag.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention features several baffles along the edge of the weighing platform, with an electromagnet positioned on the side of each baffle closest to the center of the platform. Correspondingly, it also provides a ton bag with vertical strip-shaped filling areas embedded within its four vertical edges. When the ton bag is placed on the weighing platform, activating the electromagnet attracts the magnetic filling material from the four edges, ensuring the edges are flush against the baffles and allowing the top opening to open fully. This prevents the bag opening from bending inwards and obstructing feeding. This fully automated process automates the sorting of the ton bag's top opening, eliminating the need for manual inspection and straightening, thus improving production efficiency and reducing manual labor.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown in the figure, this utility model embodiment proposes a ton bag packaging device, including a support frame, a weighing platform 5 set in the middle of the support frame, and a guide rail 7 set in the upper part of the support frame.

[0023] In this embodiment, the bracket includes a square base 1 and four support rods 2 mounted on the base 1. The support rods 2 are located at the four corners of the base 1. A mounting plate 3 is mounted on the top of each support rod 2. A feeding funnel 4 is located in the center of the mounting plate 3, with the top of the feeding funnel 4 positioned above the mounting plate 3 for connection to the feeding pipe. The bottom of the feeding funnel 4 is below the mounting plate 3 and faces downwards, symmetrically positioned at the center of the counterweight 5.

[0024] A weighing platform 5 is installed in the center of the base 1. Several baffles 6 are arranged around the edge of the weighing platform 5, with the spacing between the baffles 6 matching the size of the ton bag 9. An electromagnet 61 is installed on the side of each baffle 6 closest to the center of the weighing platform 5. Specifically, the weighing platform 5 is a square plate structure, and there are four baffles 6, vertically positioned at the four corners of the weighing platform 5. The baffles 6 are also square rods, with the electromagnets 61 positioned in adjacent areas on the two inner vertical sides of the square rods, thereby increasing the installation area and improving the attraction force. Figure 3 As shown, preferably, the electromagnets 61 on the stop bar 6 are arranged in multiple independent positions along the vertical direction. This allows the electromagnets 61 to be opened sequentially from bottom to top and cycled multiple times to achieve the leveling of the edge of the ton bag 9.

[0025] like Figure 2 As shown, in the specific design, the guide rail 7 is located in the area between the bottom of the feeding hopper 4 and the top of the baffle. The guide rail 7 is horizontally positioned, with one end extending directly above the weighing platform 5. The portion above the weighing platform 5 does not obstruct the space below the feeding hopper 4. A trolley 8 is slidably mounted on the bottom of the guide rail 7, and several hooks 81 are mounted on the bottom of the trolley 8. Further, the guide rail 7 includes two horizontally parallel tracks 71, and the trolley 8 is slidably connected to both tracks 71. In this embodiment, an electrically operated suspended guide rail 7 is used, with a specific structure similar to the existing ton bag 9 guide rail 7, which will not be described in detail. The trolley 8 is a horizontally positioned directional frame structure. The size of the hollow area in the middle of the trolley 8 is matched to the size of the weighing platform 5. There are four hooks 81, which are respectively located at the four corners of the bottom of the trolley 8. That is, when the ton bag 9 is hung on the hooks 81 by the hanging ears 91, the horizontal transport of the ton bag 9 can be achieved by the movement of the trolley 8 relative to the guide rail 7.

[0026] like Figure 4 As shown, in conjunction with this invention, a ton bag 9 is also proposed. The ton bag 9 has a hollow cubic structure. Four hanging ears 91 are provided at the four corners of the ton bag 9. Vertical strip-shaped filling areas 92 are provided inside the four vertical edges of the ton bag 9. Magnetic filler is embedded in the filling area. The magnetic filler is small steel ball particles, which does not affect the folding performance of the ton bag 9.

[0027] In operation, the four lugs 91 of the empty ton bag 9 are first hung on the four hooks 81 at the bottom of the trolley 8. Then, the ton bag 9 is transported to the weighing platform 5 via the guide rail 7. The electromagnet 61 is activated to attract the vertical edges of the ton bag 9, causing the ton bag 9 to fully open, and then loading can begin. After loading is complete, the electromagnet 61 is turned off, and the ton bag 9 can be transported away via the guide rail 7.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
