Two-side Heating devices for grid

Abstract

The invention relates to the technical field of grid machining, and discloses a two-side heating device for a grid, which includes a base, a first guide roller and a second guide roller, the first guide roller and the second guide roller are vertically and rotatably connected to both ends of the base, The front end of the base is provided with a feeding table which can move up and down along one side of the base, the base is respectively provided with heating lamps on both sides of the composite mesh grille, and an adjusting mechanism which can adjust the distance according to the weight of the composite mesh grille is arranged between the heating lamps on both sides. The invention improves the utilization rate of heat of the hot melting line and shortens the hot melting time. According tothe weight of the composite mesh grating, the distance between the composite mesh grating and the heating lamp is adjusted, so that the hot melting effect is good.

Description

technical field [0001] The invention relates to the technical field of grid processing, in particular to a heating device for both sides of a grid. Background technique [0002] The grid is one of the basic materials of the lead-acid battery. It accounts for about 25% of the total mass of the battery. The second is to conduct and collect current, so that the current is evenly distributed on the active material. Like a skeleton, the grid can be used to support active materials to form electrodes. It can be seen that the grid plays an important role in the entire production process of the battery. The above-mentioned grid is heavy, has poor corrosion resistance to sulfuric acid, short battery life, and lead pollution seriously damages the ecology, so the country is gradually eliminating it and developing a composite mesh grid, which uses carbon fiber coaxial Composite zinc wire (that is, a composite material formed by uniformly covering the surface of carbon fiber core wire ...

AI Technical Summary

Problems solved by technology

After the weaving is completed, it is necessary to heat the hot-melt wire to melt it and lock the edges on both sides of each grid belt. Now, the hot-melt wire is usually fixed by setting a heating lamp on one side of the composite mesh grid. Heating, so that only one side of the hot-melt wire can be heated, and the hot-melt wire is woven together with the composite wire, so that the hot-melt wire is distributed on both sides, which makes the hot-melt effect not good, and the composite mesh grid is prone to disconnection At the same time, the existing hot-melt wires are generally the same thickness, and the thickness of the composite wire is different, resulting in different thicknesses of the entire composite grid, while the distance between the heating lamp and the composite mesh grid remains unchanged, which will lead to excessive thermal fusion or poor heat fusion
