Embodiment Construction

[0020] This embodiment is a sealing device for the anode groove and the cathode roll of a foil machine, including a lip seal bottom plate 4, a lip seal 5, a seal plate 6, a seal plate backing plate 7, a flat washer 8, bolts 9 and lining plate 10.

[0021] Wherein: the liner 10 is in the shape of a semicircle. The bottom plate 4 of the lip seal is also in the shape of a semicircle, and is fixed on the inner surface of the liner 10 by bolts 9 and titanium flat washers 8 . The sealing plate backing plate 7 is fixed on the upper surface of the bottom plate 4 of the lip sealing strip, and is located in the middle of the bottom plate in the width direction of the sealing strip. The lip sealing strip 5 is located on the side of the upper surface of the lip sealing strip bottom plate 4 , and the lower end of the lip sealing strip is embedded in the dovetail groove on the upper surface of the lip sealing strip bottom plate 4 to be fixed. The sealing plate 6 is located on the upper su...

Abstract

A sealing device for an anode groove and a cathode roller of a crude foil engine is characterized in that a semi-arc-shaped lip sealing strip baseplate is fixed on the inner surface of a lining plate, a sealing plate base plate is fixed on the upper surface of the lip sealing strip baseplate, a lip sealing strip is located on one side of the upper surface of the lip sealing strip baseplate, the lower end of the lip sealing strip is embedded into a dovetail groove in the upper surface of the lip sealing strip baseplate to be fixed, a sealing plate is fixed on the upper surface of the sealing plate base plate, and one side edge of the sealing plate covers the upper surface of the lip sealing strip. The adopted polytetrafluoroethylene sealing plate is resistant to shock cooling and shock heating and chemical corrosion, has high lubricating non-sticky performance and favorable electric insulativity and ageing resistance, is combined with the lip sealing strip to make up for the shortcoming of high frictional resistance of an EPDM lip sealing strip, and replaces the EPDM lip sealing strip to be in contact with the cathode roller, so that the sealing is tight and reliable, the problem of side leakage of a PVC end plate is solved, and normal running of the cathode roller is guaranteed.

Description

technical field [0001] The invention relates to the electrolytic copper foil industry, in particular to a sealing device for realizing an anode groove and a cathode roller of a lithium electrolytic copper foil raw foil device. Background technique [0002] Electrolytic copper foil is the main material for the manufacture of copper clad laminates (CCL) and printed circuit boards (PCB). With the development of the world economy and the rapid development of emerging industries such as the electronics industry, communications industry, and electric vehicles, the demand for copper foil for lithium batteries has increased sharply, and the requirements for technical indicators have also greatly improved, so the accuracy and technical requirements for copper foil equipment are increasing. higher. [0003] The electrolytic copper foil raw foil machine is mainly composed of anode tank, cathode roller, winding roller and post-processing machine. Using the principle of electroplating,...
