[0043] Embodiment 1

[0044] The production process of copper foil is generally as follows: A pure copper sulfate solution is injected into the cathode tank, and the cathode roller 100 is placed in this cathode tank. By electrolyzing the copper sulfate solution, copper ions undergo a reduction reaction, and copper is deposited on the cathode roller 100. To ensure the continuous production of copper foil, the cathode roller 100 rotates in the cathode tank at a certain rate, continuously depositing copper foil on the cathode roller 100, and the stripping roller 210 on the copper foil making machine 200 continuously strips the copper foil from the cathode roller 100. However, the copper foil stripped from the cathode roller 100 has not completed the preparation yet. The stripped copper foil needs to be transmitted to the anti-oxidation tank 250 through the post-tension roller 220, the first guide roller 230, and the second guide roller 240 for anti-oxidation treatment, and then undergo processes such as roughening, curing, and organic treatment. Among them, when passing through the second guide roller 240, copper foil that exceeds the specifications is cut off, and the cut-off edge copper foil is transferred into the ear stock tank 260 through the ear stock transfer shaft. The cut-off edge material is collected using the ear stock winder and the ear stock winding shaft, facilitating the recycling of materials and reducing costs. The anti-oxidation tank 250 includes a first submerged roller 251, a second submerged roller 252, and a squeezing roller 253. The copper foil passing through the anti-oxidation tank 250 is output through the third guide roller 270 to carry out processes such as roughening and curing, as Figure 1 shown.

[0045] Among them, the stripping roller 210, the post-tension roller 220, the first guide roller 230, the second guide roller 240, the ear stock tank 260, the anti-oxidation tank 250, and the third guide roller 270 are all provided on the copper foil making machine 200. The copper foil making machine 200 is located at the front end of the cathode roller 100 to facilitate the transmission of copper foil. To save space, the ear stock tank 260 is provided below the post-tension roller 220, the first guide roller 230, the second guide roller 240, and the third guide roller 270 and is located at the front end of the cathode roller 100.

[0046] It can be understood that when cutting the copper foil or cleaning the stripping roller 210, the post-tension roller 220, the first guide roller 230, and the second guide roller 240, fine chips, water stains, and other impurities will fall to the front end of the cathode roller 100, thus affecting the quality of the copper foil.

[0047] To avoid the above problems, as shown in Figure 1 FIG., Embodiment 1 of the present application provides a shielding device 300. This shielding device 300 is located below the ear stock tank 260 and can shield the cathode roller 100 in the copper foil production system, preventing dust, water stains, copper chips, or other impurities from adhering to the roller surface of the cathode roller 100, ensuring the cleanliness of the cathode roller 100, and thus ensuring the quality of the copper foil.

[0048] In an embodiment of the present application, the shielding device 300 is provided on the copper foil production machine 200. The copper foil production machine 200 includes cross beams 280 arranged in parallel with each other, and the extending direction of the cross beam 280 is perpendicular to the axial direction of the cathode roller 100. One end of the shielding device 300 is connected to one cross beam 280, and the other end of the shielding device 300 is connected to another cross beam 280. The shielding device 300 can be unfolded in the axial direction of the cathode roller 100 to facilitate shielding the cathode roller 100.

[0049] It can be understood that the shielding device 300 can slide relative to the cross beam 280 or be fixedly connected to the cross beam 280, and can be specifically designed according to different embodiments. When the shielding device 300 is slidably connected to the cross beam 280, the folding and unfolding of the shielding device 300 can be achieved by sliding the shielding device 300 on the cross beam 280.

[0050] In addition, when the shielding device 300 is unfolded, the shielding length of the shielding device 300 is greater than or equal to the axial length of the cathode roller 100, so as to better shield the cathode roller 100 and ensure the quality of the copper foil.

[0051] It is worth mentioning that in order to avoid the shielding device 300 causing shielding when lifting the cathode roller 100, the shielding device 300 can also be folded, avoiding the removal of the shielding device 300 when lifting the cathode roller 100, simplifying the production process and improving production efficiency.

[0052] In an embodiment of the present application, the shielding device 300 includes at least two shielding components. Each shielding component includes a shielding plate and a connecting portion. The shielding plate is used to shield dust, water stains, copper chips or other impurities, ensuring the cleanliness of the surface of the cathode roller 100 and the production quality of the copper foil. The connecting portion is provided on at least one side of the shielding plate. Adjacent shielding components are connected to each other through the connecting portion, and one of the adjacent shielding components can be unfolded or folded with the connecting portion of the other shielding component as the axis to unfold or fold the adjacent shielding plates, so as to shield the cathode roller 100 or open the cathode roller 100.

[0053] The present application can adopt mechanical flipping and folding or flipping and unfolding of the shielding plate. The overall structure is simple, which is convenient for storing and using the shielding plate, can also shield the surface of the cathode roller 100, ensure the production quality of the copper foil, and is also beneficial for lifting out the cathode roller 100. Of course, other methods can also be used for the shielding device 300 as long as the shielding device 300 can be unfolded or folded.

[0054] It is worth mentioning that this baffle can be made of acid-resistant and corrosion-resistant fabric, PVC (polyvinyl chloride) board or other types to avoid the erosion of the copper sulfate solution or other corrosive liquids in the cathode tank on the baffle and ensure the shielding effect. The baffle can also be made of other materials as long as they are acid-resistant and corrosion-resistant, and no specific limitations are made here.

[0055] It should be understood that this baffle can be folded horizontally or vertically as long as it can shield the cathode roller.

[0056] When the baffle is folded horizontally, when the shielding device 300 is in the folded state, at least two baffles are arranged in sequence in the horizontal direction. When the baffle is folded vertically, when the shielding device 300 is in the folded state, at least two baffles are arranged in sequence in the vertical direction. That is, in the two folding methods, the arrangement direction and position of this baffle are different.

[0057] In the embodiment of the present application, refer to Figure 2 or Figure 3 As shown, when the shielding device 300 is in the folded state, at least two shielding components are arranged in sequence in the vertical direction. In this way, the space occupied by the shielding device 300 in the horizontal direction can be saved, so that after the shielding device 300 is folded, it will not block the cathode roller 100, and the cathode roller 100 can be lifted out more easily.

[0058] It is worth mentioning that, refer to Figure 3 As shown, in the folded state, the orthographic projections of these at least two shielding components on the horizontal plane completely coincide, that is, in the folded state, at least two shielding components are overlapped with each other. And in the folded state, the orthographic projections of at least two shielding components on the horizontal plane do not overlap with the orthographic projection of the cathode roller 100 on the horizontal plane, and the lifting out of the cathode roller 100 is not restricted, and the shielding device 300 does not need to be removed, saving costs.

[0059] It should be understood that this shielding device 300 can be two shielding components or multiple shielding components, which can be specifically designed according to different embodiments.

[0060] In some embodiments, this shielding device 300 includes a first shielding component 310 and a second shielding component 320. The first shielding component 310 and the second shielding component 320 can be folded and unfolded with each other, can shield and open the cathode roller 100, can avoid impurities such as dust or copper chips falling during production from contaminating the cathode roller 100, protect the cathode roller 100, ensure the production quality of the copper foil, and can also ensure that the cathode roller 100 can be lifted out normally. It can be understood that the shielding areas of the first shielding component 310 and the second shielding component 320 are equal to or larger than the horizontal projection area of the cathode roller 100.

[0061] In the embodiment of the present application, as shown in Figure 3 , this shielding device 300 includes a plurality of first shielding components 310 and a plurality of second shielding components 320. When the shielding device 300 is in a folded state, the plurality of first shielding components 310 and the plurality of second shielding components 320 are alternately arranged in the vertical direction in sequence. Through the plurality of first shielding components 310 and the plurality of second shielding components 320, different application scenarios can be adapted. The number of these shielding components can be increased or decreased according to requirements, thereby increasing or decreasing the shielding area of the shielding device 300 for the cathode roller 100, providing better protection for the cathode roller 100, and ensuring the production quality of the copper foil.

[0062] In the embodiment of the present application, as shown in Figure 2 and Figure 4 , each first shielding component 310 includes a first shielding plate 311, a sliding plate 312, and a first connecting portion 313. The sliding plate 312 is provided on at least one side of this first shielding plate 311. A slide rail 3120 is provided on the sliding plate 312. The extending direction of this slide rail 3120 is parallel to the unfolding direction of the first shielding plate 311. The first connecting portion 313 can slide on this slide rail 3120 when the shielding device 300 unfolds or folds, so as to drive the first shielding plate 311 to move.

[0063] In the embodiment of the present application, as shown in Figures 2 to 4 , when the shielding device 300 is in a folded state, this second shielding component 320 and the first shielding component 310 are arranged in the vertical direction, and the second shielding component 320 and the first shielding component 310 are overlapped. Each second shielding component 320 includes a second shielding plate 321, a fixing plate 322, and a second connecting portion 323. The second shielding plate 321 and the first shielding plate 311 are made of the same material and have the same structure. In the unfolded state, the first shielding plate 311 and the second shielding plate 321 are adjacent or connected, which can be specifically designed according to different implementation manners. The fixing plate 322 is provided on at least one side of the second shielding plate 321. The second connecting portion 323 is fixedly provided on the fixing plate 322. The adjacent first shielding component 310 and second shielding component 320 are connected through the second connecting portion 323 and the first connecting portion 313, and the second shielding plate 321 can move following the fixing plate 322.

[0064] Among them, the first connecting portion 313 on the first shielding component 310 is a slidable structure, such as a movable pulley; the second connecting portion 323 on the second shielding component 320 is a fixed structure, such as a fixed pulley. The first shielding component 310 and the second shielding component 320 are alternately arranged in sequence to complete the unfolding or folding of the shielding device 300, improving the convenience of retracting, releasing, and using.

[0065] In the embodiments of the present application, refer to Figures 3 to 5 As shown, when the shielding device 300 is in the folded state: the bottom of the shielding device 300 is the first shielding component 310, the top of the shielding device 300 is the second shielding component 320, and the first shielding component 310 at the bottom includes a first shielding plate 311, a sliding plate 312, and a first connecting portion 313. The second shielding component 320 at the top includes a second shielding plate 321, a fixing plate 322, and a second connecting portion 323. A plurality of first shielding components 310 and a plurality of second shielding components 320 are provided in the middle of the shielding device 300, and are alternately arranged in sequence. The first shielding component 310 in the middle includes a first shielding plate 311, a sliding plate 312, and two first connecting portions 313. The two first connecting portions 313 are both disposed in the slide rail 3120 of this sliding plate 312 and are located on opposite sides of the slide rail 3120. The second shielding component 320 in the middle includes a second shielding plate 321, a fixing plate 322, and two second connecting portions 323. The two second connecting portions 323 are respectively located on opposite sides of the fixing plate 322. The second connecting portions 323 in the second shielding component 320 in the middle are respectively connected to the first connecting portions 313 in the first shielding components 310 on opposite sides, that is, the two second connecting portions 323 on the same fixing plate 322 are respectively connected to the first connecting portions 313 in different sliding plates 312.

[0066] That is to say, one of the two second connecting portions 323 in the second shielding component 320 is connected to the first connecting portion 313 in the upper first shielding component 310, and the other is connected to the first connecting portion 313 in the lower first shielding component 310.

[0067] Wherein, in order to prevent the two first connecting portions 313 in the first shielding component 310 in the middle from colliding, an avoidance opening 3121 is further provided on this slide rail 3120.

[0068] Exemplarily, refer to Figure 3 As shown, the shielding device 300 includes four first shielding components 310 and four second shielding components 320. Among them, when the shielding device 300 is in the folded state, the bottom of the shielding device 300 is the first shielding component 310, the top of the shielding device 300 is the second shielding component 320, and the middle of the shielding device 300 includes three first shielding components 310 and three second shielding components 320. The four first shielding components 310 and the four second shielding components 320 are alternately arranged in sequence in the vertical direction, that is, from bottom to top in sequence: first shielding component 310 - second shielding component 320 - first shielding component 310 - second shielding component 320 - first shielding component 310 - second shielding component 320 - first shielding component 310 - second shielding component 320.

[0069] The working process of the shielding device 300 will be described below:

[0070] Refer to Figures 2 to 5 As shown, the shielding device 300 changes from the folded state to the unfolded state: The second connecting portion 323 of the second shielding assembly 320 at the top of the shielding device 300 is located on the left side of the fixing plate 322. Pull the second shielding assembly 320 at the top to the right, driving the first connecting portion 313 in the first shielding assembly 310 below it to move to the right in the slide rail 3120, and driving the sliding plate 312 to move to the right as well under the drive of the second shielding assembly 320. The other first connecting portion 313 located in the slide rail 3120 slides to the left in the slide rail 3120, that is, the two first connecting portions 313 slide towards the same side. To avoid collision between the two first connecting portions 313 in the same slide rail 3120 and thus affect folding and unfolding, during the movement of the sliding plate 312, the first connecting portion 313 on the right gradually moves into the avoidance opening 3121 of the slide rail 3120, while at this time the other first connecting portion 313 is above the first connecting portion 313 in the avoidance opening 3121, and the two are staggered from each other. When continuing to pull the second shielding assembly 320 to the right, the first connecting portion 313 in the avoidance opening 3121 disengages from the avoidance opening 3121, and the two first connecting portions 313 move in opposite directions respectively. When the two first connecting portions 313 are respectively located at both ends of the slide rail 3120, the second connecting portion 323 in this second shielding assembly 320 rotates with the first connecting portion 313 it is connected to as the axis, driving the fixing plate 322 to rotate and translate obliquely downward. When the fixing plate 322 and the sliding plate 312 are in the same plane, this second shielding assembly 320 and the first shielding assembly 310 are fully unfolded, and the first shielding plate 311 and the second shielding plate 321 are tightly connected to prevent impurities such as dust or copper chips from falling onto the cathode roller 100 through the gaps. Then use the first connecting portion 313 in the first shielding assembly 310 to pull the second connecting portion 323 in the second shielding assembly 320 below to move to the right, driving the fixing plate 322 to move to the right to drive the second shielding plate 321 to move to the right. Subsequently, perform the process of the second shielding assembly 320 driving the first shielding assembly 310 to move... and so on, gradually completing the unfolding of the subsequent first shielding assembly 310 and second shielding assembly 320.

[0071] Refer to Figures 2 to 5As shown, the shielding device 300 changes from the unfolded state to the folded state: in the unfolded state, all the first shielding components 310 and all the second shielding components 320 are located in the same plane. Gradually apply a pushing force to the left to push the rightmost second shielding component 320. The leftmost first shielding component 310 is subjected to a squeezing force. The first connecting portion 313 in the leftmost first shielding component 310 slides to the left in the slide rail 3120. When the first connecting portion 313 is at the leftmost end of the slide rail 3120, the second connecting portion 323 in the adjacent second shielding component 320 performs an oblique translation with the first connecting portion 313 as the axis, driving the fixing plate 322 and the second shielding plate 321 to translate obliquely upward. When the second connecting portion 323 and the first connecting portion 313 are on the same vertical line, the first connecting portion 313 and the second connecting portion 323 at the bottom side are folded. Then gradually push the shielding device 300 to the left. The first connecting portion 313 on the left rotates with the second connecting portion 323 as the axis, driving the first shielding component 310 to translate obliquely upward, and the sliding plate 312 moves to the left. The two first connecting portions 313 in the slide rail 3120 gradually move in opposite directions. When reaching the avoidance port 3121, one first connecting portion 313 is located in the avoidance port 3121, and the other first connecting portion 313 is located above it. When firmly applying a pushing force to the left, the two first connecting portions 313 move in opposite directions. When reaching the opposite ends of the slide rail 3120, the folding of the first shielding component 310 and the second shielding component 320 is completed... And so on, gradually completing the folding of the subsequent second shielding components 320 and first shielding components 310.

[0072] Through this folding and unfolding method, its overall structure is simple, and it is more convenient to use, retract and deploy. And through this folding device, the cathode roller 100 can be better protected, ensuring the cleanliness of the roller surface of the cathode roller 100, and thus ensuring the quality of the copper foil.

[0073] Of course, this shielding device 300 is not limited to unfolding to the right and folding to the left. Different unfolding and folding methods can also be designed according to different embodiments.
