Description

Technical Field

[0001] The invention belongs to the technical field of battery production, and in particular relates to a film pulling mechanism for battery box film wrapping. Background Art

[0002] After the lead-acid battery box is processed and formed, it needs to go through the last process of coating its surface with film. After the film is applied to the surface of the battery box, it can prevent the lead-acid battery box from being scratched during the subsequent transportation and assembly process. In the traditional battery production industry, the coating operation of the pole groups from the stacked plates is generally completed on a simple platform and relies on manual coating. Generally, the rectangular structure of the battery is coated on four or six sides. This traditional operation method has low work efficiency, high labor intensity, and troublesome operation. The automatic coating equipment and methods currently used in the market are generally automatic coating methods that coat the battery box at least once, but the structure and process are relatively complicated, which reduces the process operation efficiency and increases the equipment cost.

Through the functions of the film pulling mechanism and the film roll rack, the film pulling function of each side is achieved by adopting a film wrapping method in which half of the film is pasted on both sides. Compared with the traditional film wrapping method of at least one circle, the film wrapping method is changed to a half-side film wrapping method on both sides, so that the amount of film required for wrapping is greatly reduced, thereby achieving the effect of saving resources and costs. Compared with film wrapping, the operation steps and the structure of the film pulling equipment are simplified, thereby solving the above-mentioned problems of low film wrapping efficiency and complex equipment structure.
