Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid battery plates, in particular to a thickness control device for battery plate coatings. Background Art

[0002] Lead-acid batteries are the most widely used chemical power sources in the world, and the technology is very mature. As market demand develops and changes, there will be correspondingly higher requirements for the performance and life of lead-acid batteries. When producing lead-acid batteries, the plates need to be assembled on the battery. The plates are composed of grids and lead paste, and are also one of the important components of lead-acid batteries. Their thickness has a direct impact on the performance indicators of the battery.

[0003] The existing continuous casting and rolling production mode of lead-acid batteries has been fully promoted and applied, adopting a continuous production mode. Most of the existing plate coating machines are drum-type plate coating machines. The lead paste is attached to the grid, and it needs to be covered with paper on both sides before being compacted by two rollers; the two rollers are a carved roller and a flat roller. The carved roller not only compacts the lead paste, but also ensures that the plate-coating paper is in full contact with the plate; and the main function of the flat roller is to control the final thickness of the plate coating, ensure the controllability of the plate thickness, and control the final apparent density of the lead paste of the plate. Among them, the consistency of the plate thickness control reflects the consistency of the plate. Frequent fluctuations in thickness have a serious impact on the discharge pass rate of the battery after charging and formation. At the same time, if the plate lead paste is pressed too tightly, it will have a negative effect on the initial capacity of the plate. If it is not pressed in place, the plate lead paste will soften prematurely, affecting the cycle life of the lead-acid battery. Therefore, the two rollers need to be controlled within a reasonable range.

[0004] At present, various existing plate coating machines mainly use manual mechanical mode rollers to control the actual gap of the rollers, and use a wrench to adjust the roller screws to control up and down; this method has low adjustment efficiency, and the operator cannot grasp the actual gap in time during the adjustment process, and the thickness control and compaction degree of the plate cannot be effectively controlled in time, resulting in the problem of reducing the consistency of the plate thickness.
