Description

Polar plate processing smearing device and processing method for lead-acid battery production Technical Field The invention relates to the field of polar plate processing, in particular to a polar plate processing smearing device and a polar plate processing method for lead-acid battery production. Background Lead-acid batteries are widely used as energy storage devices, and the processing quality of polar plates directly influences the performance of the batteries. The polar plate smearing procedure is a key link of lead-acid battery production, and relates to uniformly coating lead plaster on the surface of a grid. Conventional application techniques face the following challenges: The limitation of a single coating mode is that the existing device mostly adopts a single roll coating mode or a knife coating mode. Although the rolling coating can rapidly process low-viscosity substances, the thickness of the high-viscosity lead plaster is difficult to accurately control, so that the surface roughness of the polar plate is increased, and the charge and discharge efficiency of the battery is affected. Although the blade coating can accurately coat the high-viscosity lead plaster, the efficiency is low when the low-viscosity substances are treated, and the waste of materials is easily caused. The adaptability is insufficient, and the traditional device cannot flexibly meet the diversified requirements of different polar plate specifications (such as thickness change) and lead paste viscosity (such as paste and liquid state). Disclosure of Invention The invention discloses a polar plate processing smearing device and a processing method for lead-acid battery production, and aims to solve the technical problems of limitation of a single smearing mode and insufficient suitability.

The coating machine I, the roll coating mechanism and the blade coating mechanism are arranged, so that the coating machine I, the roll coating mechanism and the blade coating mechanism are more suitable for low-viscosity substances during independent roll coating, the coating efficiency is high, the surface is smoother, the high-viscosity substances such as paste lead paste are more suitable for coating during independent blade coating, the thickness can be accurately controlled, the coating machine is particularly suitable for thick polar plate coating, and for coating with high quality requirements, the problems of coating uniformity and surface roughness can be synchronously improved through mixed use, so that different coating modes can be selected according to different coating requirements, and the suitability of the coating device is greatly optimized. In a preferred scheme, the waste collection mechanism comprises a waste collection cover I, a plurality of prickers, a mounting groove, a plurality of guide rails and a plurality of guide rails, wherein the waste collection cover I is positioned on one side outer wall of the scraping plate, and the bottom of the waste collection cover I is provided with an opening; the waste collection mechanism further comprises a magnetic sheet II, a magnetic sheet I, a magnetic sheet II and a magnetic sheet I, wherein the magnetic sheet II is fixedly embedded in the mounting groove; The waste collection mechanism further comprises a waste collection cover II, two communicating pipes, a waste collection cover I, a waste collection cover II and a waste collection cover II, wherein the waste collection cover II is fixedly connected to the outer wall of the other side of the scraping plate, and the bottom of the waste collection cover II is simultaneously provided with an opening; The waste collection mechanism further comprises two material passing hoses which are fixedly communicated with two ends of the
