Description

Technical Field

[0001] The invention belongs to the technical field of battery production, and particularly relates to an acid spraying mechanism for lead-acid battery plates. Background Art

[0002] In the production process of lead-acid battery plates, acid spraying and rolling are required after coating the plates, which can increase the water content of the lead paste of the plates, increase the strength of the lead paste on the plate surface, reduce the lead sulfate content on the plate surface, inhibit the formation of lead sulfate during battery discharge, and improve the conductivity of the lead paste on the plate surface, thereby improving the overall performance of the battery.

[0003] A Chinese patent with the authorization announcement number CN103762339B discloses a battery plate acid shower device, which uses upper and lower acid pressing rollers to apply acid liquid on the upper and lower surfaces of the battery plate that moves between the upper and lower acid pressing rollers, thereby realizing the acid shower operation of the battery plate. Although the above device can realize the acid shower of the battery plate, there are still the following disadvantages: after the battery plate passes through the upper and lower acid pressing rollers, the acid liquid located on the lower surface of the battery plate will drip from the battery plate due to the action of gravity, which not only causes the acid shower thickness on the upper and lower surfaces of the battery plate to be different, but also causes problems such as acid liquid waste, affecting the production quality of the battery plate. Therefore, it is urgent to study an acid shower mechanism for lead-acid battery plates in order to solve the above problems. Summary of the invention

During use, the battery plate that has not been acid-treated is first placed on a material transport assembly 2, and one surface of the battery plate (the surface is at the upper part of the battery plate at this time) is acid-treated and dried by using the acid-treatment assembly 4 and the drying assembly 5 on the material transport assembly 2. Then, the battery plate on which only one surface has been acid-treated is flipped 180° to another material transport assembly 2 by the turning assembly 3, and then the other surface of the battery plate (the surface is at the upper part of the battery plate at this time, and the surface that has been acid-treated is at the lower part of the battery plate) is acid-treated and dried by using the acid-treatment assembly 4 and the drying assembly 5 on the other material transport assembly 2.
