[0028] During the production process of electrolytic copper foil, when the cathode roller rotates, the electrolyte will be squeezed out and flow into the waste liquid tank through the overflow port. When the electrolyte flows into the waste liquid tank, part of the electrolyte will be splashed back to the cathode roller. The electrolyte splashed back to the surface of the cathode roller will affect the foil surface state of the electrolytic copper foil, resulting in defects such as foil surface spots and crescent marks on the foil surface.

[0029] Please refer to Figure-1 Figure 4 In order to solve the problem that the electrolyte easily splashes back to the cathode roller 100, the present application provides a splash-proof device, which is arranged between the cathode roller 100 and the dirty liquid tank (not shown in the figure), and the splash-proof device includes a buffer part 200 and a liquid shielding plate 300. The buffer part 200 is provided with a buffer slope 211 arranged toward the cathode roller 100, and the liquid shielding plate 300 is horizontally arranged above the buffer slope 211.

[0030] Specifically, in one embodiment, the liquid shielding plate 300 is installed above the buffer portion 200 . It should be noted that the liquid shielding plate 300 may be connected to the buffer portion 200 or to the support platform.

[0031] But not limited thereto, in other embodiments, the liquid shielding plate 300 may also be suspended above the buffer portion 200 .

[0032] like Figure 2 As shown, the liquid shielding plate 300 is arranged at an acute angle with the buffer slope 211 and surrounds the buffer groove 310, so that the electrolyte on the surface of the cathode roller 100 can impact the buffer slope 211 and enter the buffer groove 310. The buffer part 200 and the cathode roller 100 are arranged to form a liquid gap 230 connected to the buffer groove 310, so that the electrolyte in the buffer groove 310 can flow into the dirty liquid tank through the liquid gap 230.

[0033] With such a configuration, the electrolyte on the surface of the cathode roller 100 will move away from the cathode roller 100 toward the buffer slope 211 under the influence of its own inertia and gravity, and the electrolyte impacting the buffer slope 211 will quickly enter the buffer tank 310, and the high-speed flowing electrolyte will form turbulence in the buffer tank 310 and greatly reduce its own flow rate. When the electrolyte in the buffer tank 310 reaches a certain amount, under the guidance of the buffer slope 211, the electrolyte will flow into the liquid gap 230 along the buffer slope 211, and enter the dirty liquid tank through the liquid gap 230. At this time, the flow rate of the electrolyte is greatly reduced and will not splash back to the cathode roller 100.

[0034] Furthermore, in one embodiment, the vertical height of the buffer slope 211 is greater than the vertical height of the rotation axis of the cathode roller 100 .

[0035] Such a configuration is more conducive to the electrolyte on the surface of the cathode roller 100 entering the buffer tank 310, thereby reducing the probability of electrolyte splashing back.

[0036] In one embodiment, the included angle A between the buffer slope 211 and the liquid shielding plate 300 satisfies 30°≤A≤60°. Preferably, A is equal to 45°.

[0037] 30°≤A is conducive to preventing the angle A between the buffer slope 211 and the liquid shielding plate 300 from being too small, which makes it difficult for the electrolyte to enter the buffer slope 211. Obviously, the larger A is, the closer the buffer slope 211 is to a vertical state. Therefore, A≤60° can prevent the buffer slope 211 from being too steep relative to the horizontal plane, which can prevent the electrolyte from leaving the buffer tank 310 too fast. That is, such a setting can control the flow rate of the electrolyte within a safe range.

[0038] In one embodiment, if Figure 1-Figure 3 As shown, the splash-proof device further includes a movable adjustment part, and the buffer part 200 is installed on the movable adjustment part. The movable adjustment part can drive the buffer part 200 to move toward or away from the cathode roller 100 to reduce or increase the liquid gap 230.

[0039] In this way, the size of the liquid gap 230 can be adjusted according to the flow rate of the electrolyte, the rotation speed of the cathode roller 100, and the foil surface state of the electrolytic copper foil, that is, the distance between the buffer slope 211 and the cathode roller 100 can be adjusted. For example, when the flow rate of the electrolyte increases or the rotation speed of the cathode roller 100 increases, the buffer part 200 can be driven to move in a direction away from the cathode roller 100 by moving the adjustment part, so that the buffer slope 211 can accurately receive the electrolyte. Conversely, when the flow rate of the electrolyte decreases or the rotation speed of the cathode roller 100 slows down, the buffer part 200 can be driven to move in a direction close to the cathode roller 100 by moving the adjustment part, so that the buffer slope 211 can accurately receive the electrolyte.

[0040] Further, in one embodiment, if Figure 1 and Figure 3 As shown, the moving and adjusting part includes a first conveyor belt mechanism 400 and a second conveyor belt mechanism 500, which are arranged at intervals along the axial direction of the cathode roller 100, and one end of the buffer part 200 is installed on the first conveyor belt mechanism 400, and the other end is installed on the second conveyor belt mechanism 500. In addition, the first conveyor belt mechanism 400 and the second conveyor belt mechanism 500 can drive the two ends of the buffer part 200 to move synchronously to adjust the distance between the buffer part 200 and the cathode roller 100.

[0041] In this way, the distance between the buffer part 200 and the cathode roller 100 can be adjusted more conveniently.

[0042] Specifically, in one embodiment, if Figure 1 and Figure 3 As shown, the first conveyor belt mechanism 400 includes a first driving wheel 410, a first driven wheel 420, and a first conveyor belt 430 respectively wound around the first driving wheel 410 and the first driven wheel 420, the second conveyor belt mechanism 500 includes a second driving wheel 510, a second driven wheel 520, and a second conveyor belt 530 respectively wound around the second driving wheel 510 and the second driven wheel 520, and one end of the buffer part 200 is installed on the first conveyor belt 430, and the other end is installed on the second conveyor belt 530.

[0043] In one embodiment, the first conveyor belt 430 is meshed and connected to the first driving wheel 410 and the first driven wheel 420 , respectively. Similarly, in one embodiment, the second conveyor belt 530 is meshed and connected to the second driving wheel 510 and the second driven wheel 520 , respectively.

[0044] Such a configuration is helpful to prevent the first conveyor belt 430 and the second conveyor belt 530 from slipping, and improve the adjustment accuracy of the first conveyor belt mechanism 400 and the second conveyor belt mechanism 500.

[0045] Furthermore, in one embodiment, if Figure 1and Figure 4 As shown, the buffer part 200 includes a buffer plate 210 and a fixed plate 220 which are arranged at an angle and fixedly connected, and the buffer slope 211 is arranged on the side of the buffer plate 210 away from the fixed plate 220. The first conveyor belt 430 is provided with a first slot, and the second conveyor belt 530 is provided with a second slot. One end of the fixed plate 220 is clamped in the first slot, and the other end is clamped in the second slot.

[0046] In this way, the difficulty of assembling the buffer portion 200 and the movable adjustment portion is greatly reduced.

[0047] But it is not limited thereto, in other embodiments, the buffer portion 200 and the movable adjustment portion may be connected by fasteners or welded.

[0048] In one embodiment, if Figure 1 As shown, the first conveyor belt mechanism 400 further includes a first adjustment handle 440 , which is connected to the first driving wheel 410 , and the operator can drive the first driving wheel 410 to rotate through the first adjustment handle 440 .

[0049] But not limited to this, in other embodiments, the first adjustment handle 440 can also be replaced by a first motor. In this way, the adjustment accuracy can be improved and the workload of the operator can be reduced, which is conducive to improving the convenience of adjustment.

[0050] Similarly, in one embodiment, if Figure 1 As shown, the second conveyor belt mechanism 500 further includes a second adjusting handle 540 , which is connected to the second driving wheel 510 . The operator can drive the second driving wheel 510 to rotate through the second adjusting handle 540 .

[0051] However, it is not limited to this. In other embodiments, the second adjustment handle 540 can also be replaced by a second motor. In this way, the adjustment accuracy can be improved and the workload of the operator can be reduced, which is conducive to improving the convenience of adjustment.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
