Description

Technical Field

[0001] The utility model relates to the technical field of cathode roller polishing, in particular to a polishing device for an electrolytic copper foil cathode roller. Background Art

[0002] When producing copper foil by electrolysis, the cathode roller needs to be polished, because when the surface of the cathode roller is not smooth or has defects, it will cause uneven quality or reduced quality of the copper foil. Therefore, when using the electrolysis method to produce copper foil, it is necessary to ensure that the surface of the cathode roller is smooth, that is, it needs to be polished. During polishing, dust from the cathode roller will fly everywhere, resulting in a poor polishing working environment, and the grinding sandpaper will also be affected by temperature, resulting in reduced polishing quality.

[0004] Based on this, the technical problem to be solved in this case is: how to provide a polishing device with good cooling effect and dust collection. Utility Model Content

[0015] Example 1

[0016] See also Figure 1-4 A polishing device for a cathode roller of an electrolytic copper foil comprises a frame 1, a polishing mechanism 2, and a driving mechanism 3, wherein the polishing mechanism 2 is connected to the top of the frame 1, and the driving mechanism 3 is connected to the bottom of the polishing mechanism 2, and the driving mechanism 3 is used to drive the cathode roller to rotate. The device also comprises a cooling mechanism 4 and a collecting mechanism 5, wherein the cooling mechanism 4 is connected to one side of the frame 1, and the collecting mechanism 5 is connected to the frame 1, and the cooling mechanism 4 is used to provide a water source for the frame 1, and make the liquid level in the frame 1 higher than the cathode roller or tangent to the highest point of the cathode roller, and the collecting mechanism 5 is used to collect dust floating on the water surface.

[0017] In actual application, the staff provides water source to the frame 1 through the cooling mechanism 4, and controls the water surface to cover the highest point of the cathode roller. During polishing, the water absorbs the heat generated by polishing by contacting with the water, thereby reducing the temperature generated during polishing. During polishing, the dust generated by polishing has a smaller density and will float on the water surface, which can prevent the dust from flying everywhere. On the other hand, the dust floating on the water surface is collected by the collecting mechanism 5, which is convenient for the staff to clean the polishing work site after polishing.

[0018] Furthermore, the cooling mechanism 4 includes a water tank 41 and a water pipe 42 , and the water tank 41 is connected to the inside of the rack 1 through the water pipe 42 .

[0021] Through the above design, the funnel-shaped collecting hopper 51 can guide the dust floating on the water surface downward through the inner surface of the funnel. In particular, the liquid level can be appropriately increased through the water pipe 42 to make it easier for the dust to be collected through the collecting hopper 51, thereby improving the work efficiency of collecting dust.

[0022] More preferably, it further comprises a collecting pipe 52 and a recovery box 53 , wherein the recovery box 53 is connected to one end of the frame 1 , and the recovery box 53 is connected to the collecting bucket 51 through the collecting pipe 52 .

The polishing unit 22 is connected to the driving unit 21, and the lifting unit 23 is connected to the driving unit 21. The lifting unit 23 is used to drive the driving unit 21 upward or downward.

[0025] In the above design, the polishing unit 22 can move upward or downward, specifically, the downward movement is the polishing working state, and the upward movement is the static state, and the driving unit 21 drives the polishing unit 22 to move along the axial direction of the cathode roller, thereby completing the grinding of the cathode roller.

[0026] Furthermore, the lifting unit 23 includes a fixed plate 231, a lifting plate 232, and a driving cylinder 233 connected between the fixed plate 231 and the lifting plate 232, the fixed plate 231 is fixedly connected to both sides of the frame 1, the lifting plate 232 is located above the fixed plate 231, and the driving unit 21 is connected to the lifting plate 232.

[0027] Through the above design, the lifting plate 232 will drive the driving unit 21 upward or downward, thereby driving the polishing unit 22 upward or downward, and the working state of the polishing unit 22 can be better controlled by driving the cylinder 233.

[0028] Furthermore, the polishing unit 22 includes a grinding sheet 221 and a support plate 222 . A spring 223 is provided on the support plate 222 . The support plate 222 is connected to the driving unit 21 via the spring 223 . The grinding sheet 221 is fixedly connected to the support plate 222 .

[0029] In this embodiment, the spring 223 can provide a buffering and shock-absorbing effect for the support plate 222 , thereby increasing the service life of the sanding sheet 221 .

[0030] Preferably, the driving unit 21 is a motor screw module, and the support plate 222 is connected to the motor screw via a spring 223 .

[0031] In this embodiment, the grinding sand sheet 221 is driven by a motor screw and moves along the axial direction of the screw, that is, the axial direction of the cathode roller.
