Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to a grid winding anti-loosening tooling. Background Technology

[0002] The grid is the current-collecting skeleton of the electrodes in a lead-acid battery. It usually has a grid-like structure and serves as the carrier of active materials and the conductor of current. The grid provides a supporting structure for the active materials, enabling them to form a stable electrode structure.

[0003] After the grid is produced, it needs to be wound onto a take-up roller for winding and finishing. The take-up roller includes a base plate and a roller body set on the base plate. The roller body is generally equipped with a fixing part to fix the inner end of the grid. After the inner end of the grid is fixed on the roller body, the roller body rotates with the base plate, and the grid is wound onto the roller body. However, the take-up roller lacks a limiting device for the outer end of the grid. After the grid is wound, it is easy for it to open due to its own tension, causing the wound grid to loosen on the take-up roller. Summary of the Invention

[0004] This invention addresses the problem of insufficient limiting of the outer end of the winding roller used for winding grids by providing a grid winding anti-loosening tool, which can prevent the wound grid from loosening and improve the winding quality of the grid.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A plate winding anti-loosening fixture includes a base plate, a roller body located in the center of the top surface of the base plate, and multiple limiting members arranged in a circular array along the center of the base plate. Each limiting member includes a sliding groove, a connecting plate one, and a connecting plate two. The sliding groove is located on the top surface of the base plate outside the roller body, with its opening facing upwards. The outer end of the sliding groove penetrates the circumference of the base plate. The inner end of the opening of the sliding groove is sealed by a sealing plate. The connecting plate one is slidably disposed in the sliding groove below the sealing plate. The inner end of the connecting plate one is connected to the inner end of the sliding groove via a spring, and the outer end is hinged to the connecting plate two. A screw is threadedly connected to the connecting plate two along its length. The outer end of the top surface of the connecting plate one has a threaded hole corresponding to the screw. When the outer end of the connecting plate two faces upwards, the screw and the threaded hole are coaxial.

[0007] Furthermore, the top surface of each sealing plate is flush with the top surface of the bottom plate, the width of each connecting plate corresponds to the width of the slide groove, and the thickness of the connecting plate corresponds to the distance between the sealing plate and the inner bottom surface of the slide groove.

[0008] Furthermore, the top surface of each of the connecting plates is lower than the upper end of the slide groove, and the width of each of the connecting plates corresponds to the width of the slide groove.

[0009] Furthermore, there is a gap between the inner end of the connecting plate two on the front limiting member of the base plate and the outer end of the connecting plate one. The outer end face of the connecting plate one has symmetrical U-shaped grooves. The inner end face of the connecting plate two is fixed with a connecting rod corresponding to each U-shaped groove. The inner end of each connecting rod extends into the corresponding U-shaped groove. The left and right sides of each connecting rod are rotatably connected to the left and right sides of the U-shaped groove via a rotating shaft.

[0010] Furthermore, the length of the connecting plate of each of the limiting members is greater than the distance between the outer end of the sealing plate and the outer end of the corresponding slide groove.

[0011] Furthermore, each of the connecting plates is provided with a threaded hole corresponding to the screw. The threaded hole penetrates the inner and outer end faces of the connecting plate, and the outer end of the screw is connected to a drive plate.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] After the grid is wound on the roller, the present invention pulls the connecting plate one and connecting plate two corresponding to the outer end of the grid, and connects the connecting plate two vertically to the connecting plate one. Under the restoring force of the spring, the connecting plate two completes the pressing and limiting of the outer end of the grid, which prevents the grid from loosening after winding and improves the winding quality of the grid.
