Abstract
Description
Technical Field
[0001] This utility model relates to the field of lead-acid battery processing technology, and in particular to a paste-applying device for processing lead-acid battery grids. Background Technology
[0002] The grid is one of the most important components of a lead-acid battery. After the grid is produced, lead paste needs to be applied to it. The existing lead paste application equipment uses a coating machine to complete this task. One of the important pieces of equipment in the coating machine is the coating hopper. When the existing coating hopper applies lead paste to grids with a large width, the lead paste tends to be uneven at the coating roller after the grid passes through the coating roller. This affects the quality of the grid after coating and increases the manufacturing cost. Utility Model Content
[0003] The purpose of this invention is to solve the problem in the existing technology where, after the paste hopper fills the grid with a large width, the paste is applied unevenly at the coating roller after the grid is squeezed by the coating roller, thus affecting the quality of the grid after paste application. Therefore, this invention proposes a paste application device for processing lead-acid battery grids.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A paste-coating device for processing lead-acid battery grids is designed, including a base, several support columns are provided on both sides of the top of the base, a housing is installed between the tops of the several support columns on both sides of the top of the base, there is a gap between the two housings, a coating roller assembly is provided inside the two housings, there is a gap between the two coating roller assemblies, a paste-coating component is provided on one side of the two coating roller assemblies, and a scraping mechanism is provided at the bottom of the two coating rollers.
[0006] The leveling mechanism includes a pneumatic telescopic rod installed inside the housing, a scraper mounted on the top of the pneumatic telescopic rod, and one side of the scraper abutting against the outside of the coating roller assembly.
[0007] Preferably, each of the two scrapers is provided with a connecting plate on one side, each of the two connecting plates is provided with a collection trough, and each of the two collection troughs is provided with a discharge component.
[0008] Preferably, a connecting seat is installed at the top center of the base, a movable rod is slidably disposed on the connecting seat, and a placement seat is disposed at the top of the movable rod.
[0009] Preferably, the top of the placement seat has a slot.
[0010] Preferably, a protective shell is provided on the outer side of the top of the base.
[0011] The present invention discloses a paste-coating device for processing lead-acid battery grids. The beneficial effect is that, after the two coating roller assemblies have finished applying paste, during the continued operation of the two coating roller assemblies, the two scrapers scrape the excess parts on the outer side of the coating roller assemblies, making it less likely for the paste to be uneven on the outer side of the two coating roller assemblies, thereby improving the quality of the paste application on the grids by the two coating roller assemblies.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Example 1: Refer to Figure 1-3 A paste-coating device for processing lead-acid battery grids includes a base 1, with several support columns 2 on both sides of the top of the base 1, and a housing 3 installed between the tops of the support columns 2 on both sides of the top of the base 1. There is a gap between the two housings 3, and a coating roller assembly 4 is installed inside each of the two housings 3. There is a gap between the two coating roller assemblies 4, and a paste-coating assembly 5 is installed on one side of each of the two coating roller assemblies 4. A scraping mechanism is installed at the bottom of each of the two coating rollers 4, and a protective shell 15 is installed on the outer side of the top of the base 1.
[0018] The leveling mechanism includes a pneumatic telescopic rod 6 installed inside the housing 3. A scraper 7 is installed on the top of the pneumatic telescopic rod 6. One side of the scraper 7 is attached to the outside of the coating roller assembly 4. A connecting plate 8 is provided on one side of each of the two scrapers 4. A collection trough 9 is provided on each of the two connecting plates 8. A discharge assembly 10 is provided at each of the two collection troughs 9.
[0019] After the paste-coating assembly 5 starts working, its nozzles spray the coating roller assembly 4 with paste, covering the outer side of the coating roller assembly 4. Then, the grid to be coated is lowered from the top of the two coating roller assemblies 4. As the grid passes through the two coating roller assemblies 4, both sides of the grid are squeezed by the two coating roller assemblies 4, making it less likely for the paste to fall off the outer side of the grid after the two coating roller assemblies 4 have applied the paste. Moreover, after the two coating roller assemblies 4 have finished applying the paste, as the two coating roller assemblies 4 continue to work, the two scrapers 7 scrape off any excess parts on the outer side of the coating roller assemblies 4, making it less likely for the paste to be uneven on the outer side of the two coating roller assemblies 4, thereby improving the quality of the paste application to the grid by the two coating roller assemblies 4.
[0020] Example 2: An optimization based on Example 1, with reference to... Figure 1-3 A connecting seat 11 is installed at the top center of the base 1. A moving rod 12 is slidably mounted on the connecting seat 11. A placement seat 13 is provided at the top of the moving rod 12. A slot 14 is provided at the top of the placement seat 13.
[0021] The slot 14 is aligned with the area between the two coating roller assemblies 4. The top of the connecting seat 11 is provided with an elastic element 16. One end of the elastic element 16 is installed at the bottom of the placement seat 13, so that the slot 14 is connected to the coated grid, which reduces the impact force of the grid on the base 1, making it less likely for the coating on both sides of the grid to fall off, thereby reducing the number of times the grid needs to be reworked.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
