Description

Technical Field

[0001] The utility model relates to the technical field of cathode roller protection, and specifically relates to an anti-oxidation protective cover for a cathode roller. Background Technique

[0002] As the core and key component of the complete set of electrolytic copper foil equipment, the quality of the cathode roller determines the grade and quality of the copper foil, and it is called the heart of electrolytic copper foil production. Electrolytic copper foil is obtained by the reduction and deposition of copper ions in the electrolyte on the surface of the cathode roller under the action of an external power supply. Therefore, the surface state of the cathode roller directly affects the quality of the copper foil. During long-term use, the cathode roller will be oxidized by the air to form an oxide layer. If the oxide layer is too thick, it will affect the quality of the copper foil. The existing anti-oxidation protective cover for the cathode roller uses a spray pipe to spray a layer of isolation layer on the cathode roller to reduce the oxidation of the roller surface. However, during the spraying process, due to the rotation of the cathode roller itself, the sprayed liquid has a more obvious tendency to flow along the rotation direction, and the flow amplitude along the axial direction is less, so it is impossible to quickly form a sprayed liquid covering layer on the cathode roller, resulting in the isolation layer formed on the cathode roller not being continuous and prone to missing areas, and then causing this part of the cathode roller to be oxidized. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-oxidation protective cover for a cathode roller to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an anti-oxidation protective cover for a cathode roller, including a cover and a cathode roller, the cover covers the cathode roller, a spray pipe is arranged inside the cover, and an auxiliary mechanism is arranged on the outer wall of the spray pipe;

[0005] The auxiliary mechanism includes a mounting plate and a limiting rail. The limiting rail is fixedly installed on the outer wall of the spray pipe. The mounting plate is fixedly installed on the top of the cover. A motor is fixedly installed on the top of the mounting plate. The output end of the motor is fixedly installed with a rotating shaft. The top end of the rotating shaft is fixedly installed with a turntable. The top edge of the turntable is rotationally connected with a connecting rod through a pin shaft. The end of the connecting rod far away from the turntable is rotationally connected with an L-shaped rod through a pin shaft. The bottom end of the L-shaped rod is fixedly installed with a fixing ring. The fixing ring is fixedly sleeved on the spray pipe. A slider is slidably arranged inside the limiting rail. The slider is fixedly installed on the outer wall of the mounting plate.

[0006] Further, a plurality of holes are formed in the outer wall of the cover, and an acrylic plate is fixedly installed in the holes.

[0007] Further, an air inlet port is communicated with the acrylic plate on one side of the cover close to the spray pipe, and an air inlet pipe is communicated with the end of the air inlet port.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The spraying liquid is sprayed onto the cathode roller through the spray pipe to form a spraying liquid covering layer for anti-oxidation. The motor drives the rotation of the rotating shaft, and then drives the rotation of the turntable. The rotation of the turntable pulls the connecting rod, causing the L-shaped rod to move back and forth, and then driving the spray pipe to move back and forth, so that the spray pipe can move along the axial direction of the cathode roller, ensuring that the spray pipe can fully spray the cathode roller, and then forming a continuous and complete spraying liquid covering layer on the cathode roller;

[0013] 2. The air suction device is connected to the intake port through the intake pipe, and the mist volatilized from the electrolyte during electrolysis is pumped away, avoiding the attachment of acid mist points on the surface of the copper foil, corroding the copper foil, forming red dots and black dots, and causing abnormal internal and external quality of the copper foil product.

The bottom end of the L-shaped rod 305 is fixedly installed with a fixing ring 304. The fixing ring 304 is fixedly sleeved on the spray pipe 2. A slider 303 is slidably arranged inside the limiting rail 302. The slider 303 is fixedly installed on the outer wall of the mounting plate 301. The cover 1 is provided to protect the cathode roll 5 from dust. The spray pipe 2 sprays a spray liquid onto the cathode roll 5 to form a spray liquid covering layer for anti-oxidation. The spray pipe 2 is limited by the slider 303 and the limiting rail 302, so that the spray pipe 2 can only move back and forth relative to the mounting plate 301. The spray pipe 2 is connected to the L-shaped rod 305 through the fixing ring 304, so that the L-shaped rod 305 can also only move back and forth relative to the mounting plate 301. The motor 309 drives the rotating shaft 308 to rotate, and then drives the turntable 307 to rotate. The rotation of the turntable 307 pulls the connecting rod 306, so that the L-shaped rod 305 moves back and forth, and then drives the spray pipe 2 to move back and forth, so that the spray pipe 2 can move along the axial direction of the cathode roll 5, ensuring that the spray pipe 2 can fully spray the cathode roll 5, and then forming a continuous and complete spray liquid covering layer on the cathode roll 5;

[0025] There are two air inlet ports 6, which are symmetrically distributed before and after about the center of the cathode roller 5. The air inlet ports 6 face the cathode roller 5 to ensure the extraction efficiency of the mist volatilized during the electrolysis of the electrolyte.
