Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery shrink-fitting and segmentation technology, specifically to a battery shrink-fitting and segmentation structure. Background Technology
[0002] Heat shrink packaging is a common method used in battery manufacturing and packaging to protect batteries and provide additional security. Currently, various heat shrink packaging methods exist on the market, such as PVC heat shrink packaging of four batteries at a time or two batteries at a time. However, for situations requiring individual battery heat shrink packaging, existing solutions often rely on manual operation, which is not only inefficient but also costly. Manual heat shrink packaging is not only time-consuming but also prone to inconsistent quality, affecting overall product quality and production efficiency.
[0003] In light of this, some battery manufacturers and suppliers have begun seeking automation solutions to improve the efficiency and consistency of individual battery heat shrink packaging. Although some automated heat shrink machines have emerged on the market, these devices are typically designed for high-volume production, and there is still a lack of efficient and economical solutions for heat shrinking individual batteries.
[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a battery shrink-fit segmentation structure. Utility Model Content
[0005] The purpose of this invention is to provide a battery shrink-fit and segmented structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A battery shrinking and segmentation structure technical solution includes a conveying assembly. A product unloading fixing channel for fixing battery products is provided above the conveying assembly. A battery pushing mechanism is provided on the adjacent side of the conveying assembly. The battery pushing mechanism includes a base, on which a pushing cylinder is mounted. Two sets of pushing rods are arranged in parallel on the pushing cylinder. Pushing seats are installed at the ends of the two sets of pushing rods. The pushing seats are used to push the battery products. A slitting machine is provided above the conveying assembly, and multiple sets of slitting blades are installed inside the slitting machine.
[0008] As a preferred technical solution, the slitting machine is provided with a frame on the adjacent side, a heating blower is installed on the top of the frame, a heating hood is provided at the output end of the heating blower, and the air outlet of the heating hood is arranged downward.
[0009] As a preferred technical solution, the slitting machine is equipped with an upper connecting rod, and a lower connecting rod is provided on the outside of the frame. The upper connecting rod and the lower connecting rod are connected by a linkage spring.
[0010] As a preferred technical solution, the linkage spring is used to provide a reverse force to the slitting machine and the slitting blade, ensuring that the slitting blade will not cut the battery product.
[0011] As a preferred technical solution, the conveying assembly consists of a main power roller and a secondary power roller. The shaft end of the main power roller is connected to a drive motor, and the main power roller and the secondary power roller are connected by a conveyor belt for conveying battery products.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention relates to a battery shrink-packing and segmentation structure, which significantly improves the speed of heat-shrink packaging individual batteries, thereby increasing overall production efficiency. This structure reduces reliance on manual operation, saving substantial labor costs, especially in large-scale production where cost savings are even more significant. For customers with large orders, this structure can increase daily production capacity by up to 20 times, greatly enhancing the capacity of individual battery heat-shrink packages. Automated equipment ensures consistent quality for each battery heat-shrink package, reducing quality issues caused by manual operation. Simultaneously, automation reduces direct human involvement in the heat-shrink packaging process, thereby lowering safety risks. The structural design can adapt to the needs of heat-shrinking different quantities of batteries, efficiently handling both single batteries and multiple battery combinations. The simplicity of the structure facilitates maintenance and operation, helping to reduce equipment downtime and improve operational efficiency. The design of the heating blower and linkage spring optimizes energy use, reducing unnecessary energy waste. Attached Figure Description

[0017] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.
[0018] like Figure 1 , Figure 2 As shown, this utility model provides a battery shrink-fit and segmentation structure technical solution: it includes a conveying assembly, which includes a main drive roller 11 and a secondary drive roller 12. The shaft end of the main drive roller 11 is connected to a drive motor (not shown in the figure) for driving the movement of the conveying assembly. The main drive roller 11 and the secondary drive roller 12 are connected by a conveyor belt 13 for conveying the battery product 3.
[0019] A product unloading and fixing channel 2 is set above the conveying component to fix the battery product 3 and ensure that the battery product remains stable during the conveying process.
[0020] A battery pushing mechanism is provided on the side adjacent to the conveying component. The mechanism includes a base 31, on which a pushing cylinder 32 is mounted. Two sets of pushing rods (not shown in the figure) are arranged in parallel on the pushing cylinder 32. Pushing seats 33 are installed at the ends of the two sets of pushing rods. The pushing seats 33 are used to push the battery product 3.
[0021] A slitting machine 4 is installed above the conveyor assembly, and multiple sets of slitting blades 41 are installed inside the slitting machine 4. The slitting machine 4 is used to divide the battery products 3 after they pass through, ensuring that each battery product can be individually heat-shrink packaged.
[0022] A frame 5 is installed on the adjacent side of the slitting machine 4, and a heating blower 51 is installed on the top of the frame 5. A heating hood 52 is connected to the output end of the heating blower 51. The air outlet of the heating hood 52 is set downwards to heat the battery product 3 for heat shrink packaging.
[0023] The slitting machine 4 is equipped with an upper connecting rod 53, and a lower connecting rod 54 is provided on the outside of the frame 5. The upper connecting rod 53 and the lower connecting rod 54 are connected by a linkage spring 55. The linkage spring 55 is used to provide a reverse force to the slitting machine 4 and the slitting blade 41 to ensure that the slitting blade 41 will not cut the battery product 3.
[0024] With the above-described structure, the conveying assembly of this invention is responsible for moving the battery product 3 from one position to another. The product unloading fixing channel 2 ensures that the battery product 3 does not move during the conveying process. The battery pushing mechanism is responsible for pushing the battery product 3 to the slitting machine 4 for segmentation. The slitting machine 4 and the slitting blade 41 are responsible for segmenting the battery product 3 into individual products for heat shrink packaging. The heating blower 51 and the heating hood 52 are responsible for heating the battery product 3 to facilitate heat shrink packaging. The linkage spring 55 ensures that the slitting machine 4 will not damage the battery product 3 when it is not in operation.
[0025] In summary, the battery shrink-pack segmentation structure of this utility model improves the speed and quality consistency of individual battery heat shrink packaging through automation, while reducing production costs and safety risks.
