Description
Technical field
The utility model relates to a kind of electrolytic copper foil tightness system between cathode roller and the anode slot in process of production.
Background technology
Electrolytic copper foil is that between cathode roller and the anode slot come out by electrolytic solution copper sulfate cathode roller under the effect of electric current deposition that powers in the gap.Anode slot is a first quarter moon shape arc cell body, arc inner wall is equipped with the positive plate of conduction usefulness, the inner width of anode slot is slightly larger than the width of cathode roller, in the cell body bottom rectangular fluid inlet is arranged, its length approaches the inner width of anode slot, be provided with below fluid inlet and arrange 12 of wide fluid inlets, promptly at the even feed liquor of rectangular fluid inlet, purpose is to allow electrolytic solution evenly enter anode slot to the electrolytic solution of anode slot by the feed liquor tubule.Cathode roller is cylindrical titanium roller, there is support at two ends and conducts electricity the roll shaft and the conducting ring of usefulness, during production, cathode roller centering is put on the central axis of anode slot, because the anode slot inner arc is greater than cathode roller, so between cathode roller and the anode slot certain spacing is arranged, electrolytic solution then injects from the fluid inlet of anode slot bottom endlessly, overflow before and after anode slot via the gap between cathode roller and the anode slot, make cathode roller in anode slot, rotate by transmission, cathode roller powers on and deposits Copper Foil under the effect of electric current, and carrying out rolling at the cathode roller sur-face peeling is the rolling Copper Foil.Owing between cathode roller and the anode slot spacing is arranged, spacing between cathode roller roll surface and positive plate is suitable, and the spacing of cathode roller both sides PVC ring and anode slot can cause the phenomenon of electrolytic solution to both sides side plate channelling, make cathode roller like this when producing electrolytic copper foil, the electrolyte stream on cathode roller roll surface both sides is to inequality, and the electrolytic copper foil thickness and the structure that cause cathode roller roll surface both sides to produce are all inhomogeneous, so this structure only is fit to produce the above electrolytic copper foil of thickness 20 μ m, when producing less than the following electrolytic copper foil of 20 μ m, will be because of electrolytic copper foil edge part torn edges easily in uneven thickness.
Summary of the invention
The purpose of this utility model just provides a kind of PVC ring on cathode roller both sides and spacing of anode slot of effectively preventing can cause the tightness system of electrolytic solution to both sides side plate channelling.
The utility model can be realized in the following manner: cathode roller centering is put on the central axis of anode slot, the anode slot bottom is provided with fluid inlet, with a V-arrangement India-rubber strip that highly is slightly larger than spacing between cathode roller and the anode slot, being installed in cathode roller both sides PVC respectively along the cathode roller turning direction encircles on the pairing anode slot, perhaps between the inboard of the side of cathode roller both sides PVC ring and anode slot left side plate, be provided with the PVC baffle plate respectively, the PVC baffle plate is fixed on the inboard of the side plate on anode slot both sides on one side, and the other side is adjacent to the both sides of cathode roller left and right sides PVC ring.
Anode slot of the present utility model bottom is provided with a plurality of fluid inlets, when copper sulfate electrolyte enters between cathode roller and the anode slot gap through fluid inlet continuously, because the obstruct of tightness system is arranged, copper sulfate electrolyte can only upwards overflow by the positive plate in anode slot, the copper sulfate electrolyte that fluid inlet comes out flowing in anode slot is arc line type arranged side by side substantially, makes cupric ion process of electro-deposition copper foil on cathode roller that a whole consistent condition be arranged.The breach phenomenon that can not occur torn edges or generation in uneven thickness with the electrolytic copper foil of the utility model production thickness 12 μ m, producing the following Copper Foil of thickness 8-11 μ m does not have the torn edges problem can continuous production substantially, can promote the class and the quality of electrolytic copper foil greatly, reduce production cost significantly.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A partial enlarged drawing among Fig. 1.
Fig. 3 embodiment of the present utility model.
Fig. 4 is an A-A partial enlarged drawing among Fig. 3.
In the drawings: cathode roller 1, PVC ring 2, anode slot 3, side plate 4, fluid inlet 5, V-arrangement India-rubber strip 6, PVC baffle plate 7.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described, but it is not represented as unique embodiment of the present utility model.
Embodiment one
Please read Fig. 1, cathode roller 1 centering is put on the central axis of anode slot 3, the anode slot bottom is provided with fluid inlet 5, encircle at the PVC on cathode roller 1 both sides respectively V-arrangement India-rubber strip 6 is installed on the arc cell body of 2 corresponding anode slots 3, V-arrangement India-rubber strip 6 is the installation of lying on one's side, being provided with trapezoidal end face in V-arrangement India-rubber strip bottom is used for fixing on anode slot 3, on the arc cell body of corresponding anode slot 3 is the PVC material, on the arcual anode slot of this section, be carved with the corresponding trapezoidal groove of trapezoidal end face with V-arrangement India-rubber strip 6, V-arrangement India-rubber strip 6 is bumped in this trapezoidal groove with the bottom, sees Fig. 2.
When producing electrolytic copper foil, because the height of V-arrangement India-rubber strip 6 is slightly larger than the spacing between cathode roller roll surface and the anode slot 3, cathode roller 1 is packed in the anode slot 3, when packing cathode roller 1 into, V-arrangement India-rubber strip 6 will be subjected to cathode roller 1 extruding, and the lower end of V-arrangement India-rubber strip is bumped into anode slot 3, so, when cathode roller 1 rotates owing to be subjected to the elasticity and the hydraulic effect of V-arrangement India-rubber strip 6, make V-arrangement India-rubber strip 6 and cathode roller 1 be in best sealed state, can prevent effectively that the PVC ring 2 on cathode roller 1 both sides and the spacing of anode slot 3 from can cause the phenomenon of electrolytic solution to 4 channelling of both sides side plate.
Embodiment two
Please read Fig. 3, cathode roller 1 centering is put on the central axis of anode slot 3, the anode slot bottom is provided with fluid inlet 5, between the inboard of the side of the PVC on cathode roller 1 both sides ring 2 and anode slot 3 left side plates 4, increase respectively one on the meniscate PVC baffle plate 7 of meander-like respectively, PVC baffle plate 7 is fixed on the inboard of the side plate 4 on anode slot both sides on one side, the radius of PVC baffle plate inner arc radius ratio cathode roller 1 is little, PVC baffle plate 7 the other sides are adjacent to the both sides of cathode roller 1 left and right sides PVC ring 2, it is 2 identical that PVC baffle plate inner arc radius and the PVC of cathode roller 1 encircle, and sees Fig. 4.
When producing electrolytic copper foil, PVC baffle plate 7 is fixed on the side plate 4 of anode slot 3, when copper sulfate electrolyte enters between cathode roller 1 and the anode slot 3 gap through fluid inlet 5 continuously, because the PVC baffle plate is so that crescent has certain width, under the hydraulic effect, PVC plate washer 7 can produce slight distortion, PVC plate washer deformation direction is closely attached on the PVC ring 2 on cathode roller 1 both sides more, even in cathode roller rotates, also can reach sealing effectiveness, can prevent effectively that like this PVC ring 2 on cathode roller 1 both sides and the spacing of anode slot 3 from can cause the phenomenon of electrolytic solution to 4 channelling of both sides side plate.
