Description

Technical Field

[0001] This utility model belongs to the field of ton bag technology and relates to a ton bag anti-foreign object cover bag for ton bag packaging machines. Background Technology

[0002] Currently, the operation process of ton bag packaging machines developed and designed by domestic packaging machine manufacturers is as follows: ton bags are placed on pallets, and then manually or by conveyor belt to be directly below the packaging machine. The manual person hangs the ton bag on the four robotic arms of the packaging machine. After the packaging operation is started, the robotic arms automatically lift to the designated position to start unloading and packaging. After packaging is completed, the pressure is released, the ton bag falls back to the pallet, and the manual person or by conveyor belt transfers the pallet to the next process to end the operation.

[0003] Currently, domestic battery material manufacturers, such as those producing lithium cobalt oxide precursors like cobalt tetroxide and ternary precursors, primarily use fully automated ton bag packaging machines for their products. In recent years, the market's increasing demands for the safety and cycle performance of end-use battery materials have driven up requirements for the metal foreign matter content in raw material procurement and production products, including requirements for foreign matter on the surface of product and raw material packaging. Therefore, in recent years, the industry has considered cleanroom design in the construction of new battery material production lines. However, the product packaging process remains a key focus and challenge for foreign matter control, especially given that some manufacturers' factories were built a long time ago, making the control of the packaging process even more crucial.

[0004] In light of this, manufacturers currently employ breakpoint control methods in the packaging process to reduce the risk of foreign object introduction. However, the risk of foreign object introduction still exists during product packaging. Patent 201821773541.8 discloses a ton bag for preventing foreign object introduction. In the production of battery-grade powder materials, a layer of plastic film is added to the outside of the packaging bag to prevent foreign objects from adhering to the inner packaging bag. Customers untie the top and bottom of the outer film before feeding materials, reducing the risk of foreign objects being introduced into the next process. This method has a good control effect on foreign object introduction in the downstream feeding process, but the problem of preventing foreign objects from entering the ton bag surface during product packaging remains unsolved. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the current system by providing a ton bag anti-foreign object cover bag for ton bag packaging machines.

[0006] Therefore, the present invention adopts the following technical solution;

[0007] A ton bag anti-foreign object cover for a ton bag packaging machine includes a cover body with an open bottom, a plurality of ton bag lifting lugs protective sleeves connected to the cover body on the top of the cover body, a cover body hook on the ton bag lifting lugs protective sleeves, and a ton bag inlet on the top of the cover body.

[0008] Furthermore, the cover has a rectangular structure.

[0009] Furthermore, there are four protective covers for the ton bag lifting lugs, each located at one of the top corners of the cover.

[0010] Furthermore, the protective sleeve for the ton bag lifting lugs is equipped with ton bag lifting lug hooks.

[0011] The advantages of this utility model are as follows: a rectangular cover is set to cover the ton bag and protect the surface of the ton bag. At the same time, a protective sleeve is set to protect the lifting ears of the ton bag, which effectively prevents foreign objects from contaminating the surface of the ton bag during the packaging process. The structure is simple, the manufacturing cost is low, and the use is convenient. Attached Figure Description

[0013] In the diagram, 1-cover body, 2-protective sleeve for ton bag lifting lugs, 3-hook for ton bag lifting lugs, 4-hook for cover body, 5-feeding inlet for ton bag. Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings:

[0015] like Figure 1 As shown, a ton bag anti-foreign object cover for a ton bag packaging machine includes a cover body 1 with an open bottom. The cover body 1 has a rectangular structure and its size is adapted to the size of the ton bag. The cover body 1 can be made of canvas or other common materials. In use, the cover body 1 can be moved downwards so that the ton bag enters the cover body 1 from the bottom, and then the cover body 1 directly covers the ton bag. The cover body can effectively prevent contamination of the ton bag surface during packaging. The top of the cover body 1 is provided with multiple ton bag lifting lug protective sleeves 2 that are connected to the cover body 1. The ton bag lifting lug protective sleeves 2 can be put on the ton bag lifting lugs to protect them from contamination. To protect the lifting lugs of the ton bag during the packaging process, four protective sleeves 2 are provided, each located at one of the top corners of the cover 1, corresponding to the lifting lugs of the ton bag. The protective sleeves 2 contain lifting lug hooks 3, which allow the lifting lugs to be hung on for easy lifting. Additionally, the protective sleeves 2 have cover hooks 4, which allow the cover 1 to be lifted by the ton bag packaging machine for easy operation. The top of the cover 1 has a ton bag inlet 5, through which materials can be added to the ton bag.

[0016] The method of using this utility model is as follows:

[0017] In use, first, suspend the four cover hooks 4 on the ton bag lifting lug protective sleeve 2 onto the robotic arm of the ton bag packaging machine, and then raise the height of the cover 1 by the ton bag packaging machine. Then, move the ton bag to the cover 1 and lower it. Lower the cover 1 so that the cover 1 is on the ton bag. At this time, the operator can hang the lifting lugs of the ton bag on the ton bag lifting lug hooks 3 inside the ton bag lifting lug protective sleeve 2 to open the ton bag for packaging. Finally, add materials into the ton bag through the ton bag inlet 5 at the top of the cover 1 for packaging. After packaging, lift the cover 1 and remove the ton bag lifting lugs from the ton bag lifting lug hooks 3.

[0018] This device can effectively prevent contamination of the surface of ton bags and the lifting lugs during the ton bag packaging process. It is convenient, quick, and effective.
