The utility model provides a high-purity copper target material smelting and purifying device, which relates to the technical field of high-purity copper target material smelting and purifying, and comprises a smelting furnace body and a feeding box, a discharge port of the feeding box is provided with a screw feeder, and a discharge port of the screw feeder is provided with a feed pipe communicated with a furnace cover of the smelting furnace body. The feeding box is arranged in the feeding box and used for conveying the target materials, the piston plate is arranged in the feeding box, the target materials in the feeding box move towards the opened opening and closing plate under the action of gravity to enter the spiral feeding machine, and at the moment, part of heat in the smelting furnace body enters the feeding box, but cannot leak from a box opening of the feeding box; after the target material in the feeding box is discharged, the piston plate moves in the feeding box, heat in the feeding box can be extruded out of the feeding box along the opened opening and closing plate and enters the smelting furnace body again, then the opening and closing plate is closed again, the piston plate is reset, the feeding box is reset, and heat loss of the smelting furnace body cannot be caused in the process.
