Lead valve device for casting plate machine

Abstract

The invention provides a lead valve device for a casting plate machine, which comprises a main body and a control rod component, wherein the exterior of the main body comprises a first surface, a second surface and a slide wall; the first surface is opposite to the second surface; the side wall is arranged between the first surface and the second surface; the interior of the main body comprises a first through hole and a second through hole; the first through hole simultaneously passes through the first surface and the second surface; one end of the second through hole is communicated with the first through hole while the other end passes through the side wall; a control rod interface is arranged in the position where the first through hole passes through the first surface; a liquid inlet is arranged in the position where the first through hole passes through the second surface; a turning port is arranged in the position where the second through hole is communicated with the first through hole; a liquid outlet is arranged in the position where the first through hole passes through the side wall; the control rod component is arranged in the first through hole through the control rod interface and is in close fit with the inner wall of the first through hole; and a pipeline from the liquid inlet to the liquid outlet is closed or opened. The lead valve device for the casting plate machine is simple in structure and excellent in sealing property and effectively solves the technical problem of the prior art that the lead valve is difficult to close under the influence of lead leakage.

Description

technical field [0001] The invention belongs to the field of lead-acid battery production and manufacturing, in particular to a lead valve device for a casting machine. Background technique [0002] For general lead-acid batteries, the production of the pole plate includes filling the mesh of the grid with active material, and the casting machine is the main production equipment for making the grid. The current casting machine mainly includes a lead furnace, a lead valve device, a lead cup supply mechanism, a lead spoon, a lead spoon turning mechanism, a mold, etc. The valve device and the lead cup feeding mechanism inject the lead spoon into the lead spoon, and the lead spoon is turned over at a certain frequency by the lead spoon turning mechanism, and a certain amount of lead liquid is cast into the mold each time. The lead liquid forms the grid blank in the mold, and then forms the finished grid after a series of processing. [0003] However, the lead valve device in t...

Problems solved by technology

[0003] However, the lead valve device in the prior art only includes a liquid inlet, a liquid outlet, a valve lever (to control the opening or closing of the liquid outlet) and a cavity part for containing the lead liquid, and the cavity part is only Formed by combining two halves with screws etc.

Lead leakage not only caused unnecessary material loss, but also caused the leaked lead liquid to easily form lead oxide when exposed to the air. The valve control rod of the lead valve device and the lead supply mechanism of the lead cup were "welded", making it difficult to close the lead valve. In addition, removing lead oxide also requires too much manpower and material resources
