A copper line automatic molding device for electrolytic copper foil dissolves copper
Technical Field
The invention relates to an automatic forming device for copper wires, in particular to an automatic forming device for copper wires for dissolving copper by electrolytic copper foil.
Background
The copper dissolution is the first process of electrolytic copper foil production, and whether the electrolytic copper foil can run efficiently and reliably is directly related to whether the copper foil can be produced stably and whether the quality is reliable. The company used a soak type process to prepare the copper sulfate solution. The copper dissolving tank is a key device for soaking type copper dissolving. Meanwhile, the electrolytic copper raw material adopted by the company is mainly a copper wire coil, and the whole coil is generally put into a copper dissolving tank during feeding.
In practical use, after the copper wire coil is put into the copper dissolving tank, copper ingots with smooth surfaces are formed on the periphery of an air outlet hole for supplying oxygen at the bottom of the copper dissolving tank after the copper wire coil is dissolved on the surface. This is due to the inability of air and solution to enter the interior. In this case, since the surface area of the copper material involved in the dissolution is small, when the total surface area of the copper material in the tank is reduced to a certain extent, the concentration of the formed copper sulfate solution is insufficient, and at this time, the raw material needs to be added again, but at this time, there is still a large amount of copper material at the bottom of the tank. The result of this is that during the copper dissolution process, a considerable proportion of the copper material is retained at the bottom of the can at any time.
Under the background that the price of copper raw materials is continuously increased, the copper dissolving mode invisibly occupies a considerable part of mobile capital of an enterprise, and causes resource waste, so companies encourage technical personnel to develop a scheme for solving the problem.
