Description

Technical Field

[0001] The invention relates to the technical field of lead-acid battery production and manufacturing, and more particularly to a paper covering machine for lead-acid battery plates. Background Art

[0002] The two electrodes of a chemical power source are composed of an active substance and a "collector" for support and conduction, which is generally a sheet-like porous body called a plate.

[0003] At present, there are generally two processes for the manufacture of polar plates in the lead-acid battery industry: one process is to spray acid after the plate coating machine, and then dry, collect, solidify, and form. The disadvantage of this process is that the drying is not thorough, and the grid will stick after stacking when collecting, that is, the lead paste layer coated on the surface of the grid is damaged, which increases the difficulty of subsequent curing and formation, resulting in a high scrap rate; the other process is to coat the plate, cover with paper, dry, collect, solidify, and form. This process adds a paper covering process, so that there is a gap of covering paper between the grids after collecting, which greatly improves the work efficiency and grid utilization rate. However, traditional paper covering equipment is prone to cause the covering paper and the grid to not fit tightly, and the fitting size deviation is large, and it is inconvenient to replace the paper roll.
