Problems solved by technology

If the copper particles are small or the adhesion of the copper particles on the cathode roller is less than the strength of the copper foil itself, the copper particles will be taken off the cathode roller by the copper foil when peeling off, forming burrs, and the larger copper particles will be taken off , if it falls into the gap between the poles of the anode tank, it will cause the electric shock roller; in the prior art, a simple gasket is generally used for sealing, the sealing effect is poor, and it is easy to cause gaps due to material fatigue, and the gasket needs to be replaced frequently, so it is urgently needed.

Embodiment 1

[0027] refer to Figure 1-5 This embodiment provides a sealing device for electrolytic copper foil, including support plates 2 located on both sides of the cathode roll 1 and a support frame 3 located at the bottom of the cathode roll 1, and sealing rings 4 are clamped at both ends of the cathode roll 1, An arc-shaped bottom plate 5 is fixedly connected between the support plate 2 and the support frame 3, and a base 6 is fixedly connected to the arc-shaped bottom plate 5. A sealing block 7 is clamped inside the base 6, and the top of the sealing block 7 abuts against the cathode roller 1, sealing The block 7 is provided with an accommodation groove 8, and a pretension assembly is fixedly arranged in the accommodation groove 8, and the pretension assembly is connected with a control part, and the control part and the pretension assembly are fixedly connected with a limiting part; the control part controls the pretension assembly to The sealing block 7 is supported to make the s...

Embodiment 2

[0041] refer to Image 6 , this embodiment provides a sealing device for electrolytic copper foil. The difference between this embodiment and Embodiment 1 is that there are several blades 23 fixedly connected to the hinged side of the rotating block 15 and the pull rod 21, and the blades 23 are not connected to the pull rod. 21 interferes, when the electrolyte flows to the vicinity of the rotating block 15, first move the blade 23, thereby driving the rotating block 15 to rotate, and then push the sliding block 19 to slide, when the electrolyte returns, it will drive the rotating block through the blade 23 15 is rotated in the opposite direction, so that the engaging block 16 on the rotating block 15 is away from the top block 17, and at the same time drives the sliding block 19 to slide back, preventing the accommodating groove 8 from making the sliding block 19 slide back, causing the engaging block 16 to always engage with the top block 17 , the rotating block 15 cannot tig...

Abstract

The invention discloses a sealing device for an electrolytic copper foil. The sealing device comprises supporting plates positioned on two sides of a cathode roller and a supporting frame positioned at the bottom of the cathode roller, sealing rings are clamped at two ends of the cathode roller, an arc-shaped bottom plate is fixedly connected between the supporting plates and the supporting frame, a base is fixedly connected onto the arc-shaped bottom plate, and a sealing block is clamped in the base. The top end of the sealing block abuts against the cathode roller, a containing groove is formed in the sealing block, a pre-tightening assembly is fixedly arranged in the containing groove, the pre-tightening assembly communicates with a control part, and a limiting part is fixedly connected between the control part and the pre-tightening assembly; and an anode groove is reserved between the arc-shaped bottom plate cathode roller and the supporting frame, the containing groove communicates with the anode groove, and the two sealing blocks are located at the two ends of the anode groove. The sealing device is good in sealing effect, the sealing block can be automatically pressed, and the loosening phenomenon is not prone to occurring.

Description

technical field [0001] The invention relates to the field of sealing technology, in particular to a sealing device for electrolytic copper foil. Background technique [0002] Electrolytic copper foil is an important material for the manufacture of copper clad laminates (CCL), printed circuit boards (PCB), and lithium-ion batteries. In the rapid development of today's electronic information industry, electrolytic copper foil is called the "neural network" of electronic product signal and power transmission and communication. The production process of electrolytic copper foil is simple, and there are three main processes: solution raw foil, surface treatment and product cutting. Its production process seems simple, but it integrates electronics, machinery, and electrochemistry, and is a production process that has particularly strict requirements on the production environment. Whether the sealing of the end of the cathode roll is good is the key to whether the production of ...
