Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figure 1-7 , a copper powder removal device for electrolytic copper foil comprises a bottom box 1, a limiting frame 2, a copper powder removal mechanism 3 and a placement frame 4 which are sequentially connected to the bottom box 1, and the copper foil passes through the limiting frame 2, the copper powder removal mechanism 3 and the placement frame 4 in sequence at the same height, the copper powder removal mechanism 3 is slidably connected to the bottom box 1, a through groove 34 is provided on the side of the copper powder removal mechanism 3, the through groove 34 is connected with the copper foil input end 321 and the copper foil output end 311 of the copper powder removal mechanism 3, a dust removal module 33 and a lower pressing module 35 which is used to press the copper foil down onto the dust removal module 33 and can be raised and lowered are provided in the copper powder removal mechanism 3, when the lower pressing module 35 rises and separates from the copper foil, the copper powder removal mechanism 3 can move horizontally in a direction perpendicular to the copper foil conveying, and the copper foil can separate from the copper powder removal mechanism 3 along the direction of the through groove 34.

[0020] In actual use, the copper powder removal mechanism 3 adsorbs and removes copper powder through the dust removal module 33. Specifically, the dust removal module 33 is an electrostatic dust removal roller. The dust removal module 33 can conveniently adsorb copper powder to achieve the purpose of dust removal, and the bottom box 1 can collect the copper powder. The electrostatic dust removal roller needs to be regularly maintained during use, such as regularly cleaning the surface of the electrostatic dust removal roller, checking the electrostatic generator, etc. Specifically, when maintenance is required, the staff removes the copper powder removal mechanism 3 from the bottom box 1. At this time, if the copper foil is in the copper powder removal mechanism 3, the through groove 34 is used to avoid air, that is, when the copper powder removal mechanism 3 is removed, the copper foil can be separated from the copper powder removal mechanism 3 through the through groove 34. Before removing the copper powder removal mechanism 3, in order to better protect the copper foil, the copper foil can be better separated from the copper powder removal mechanism 3 by lifting the pressing module 35. From then on, on the basis of protecting the copper foil, it is convenient for the staff to maintain the components in the copper powder removal mechanism 3.

[0021] Preferably, the copper powder removal mechanism 3 includes a dustproof plate 32 and a shell 31, the dustproof plate 32 is detachably connected to one end of the shell 31, the through groove 34 is located on one side of the shell 31, the dust removal module 33 and the downward pressure module 35 are located in the shell 31, the copper foil input end 321 is located on the dustproof plate 32, and the copper foil output end 311 is located on the side of the shell 31 away from the dustproof plate 32, and is at the same height as the copper foil input end 321.

[0022] Through the above design, the dustproof plate 32 can be removed from the outer shell 31, so that the staff can visually observe whether the parts in the copper powder removal mechanism 3 are damaged or need maintenance, and the copper foil can enter the copper powder removal mechanism 3 through the copper foil input end 321 from the dustproof plate 32, and be output from the copper powder removal mechanism 3 from the copper foil output end 311, which is conducive to removing the copper powder on the copper foil and collecting the copper powder in the bottom box 1, and can also prevent external dust from entering the copper powder removal mechanism 3.

[0023] Preferably, the outer shell 31 is provided with symmetrically arranged sliders 312 and multiple locking holes 313, the bottom box 1 is provided with multiple fixing holes 11 and symmetrically arranged guide rails 12, the sliders 312 are slidably connected to the guide rails 12, and the outer shell 31 can be fixed to the bottom box 1 through external screws through the locking holes 313 and the fixing holes 11.

[0024] In this embodiment, the shell 31 mainly has two working positions, one working position is for the purpose of removing copper powder, and the other working position is for the purpose of maintenance. In order to maintain stability during copper powder removal and facilitate maintenance by staff, the shell 31 can be locked on the bottom box 1 through the locking hole 313 and the fixing hole 11, thereby ensuring the stability of the two working positions.

[0025] More preferably, limit blocks 121 are provided on both ends of the guide rail 12 .

[0026] In order to prevent the shell 31 from being separated from the bottom box 1, the movable range of the shell 31 can be limited by the limit block 121 to ensure the safety of the staff during operation.

[0027] Furthermore, the number of the fixing holes 11 is 8, and the number of the locking holes 313 is 4. When one end of the housing 31 contacts the limiting block 121 , the positions of the fixing holes 11 and the locking holes 313 match.

[0028] In the above design, since the shell 31 mainly has two working positions, each working position has a fixing hole 11 corresponding to the working position, that is, every four fixing holes 11 determine a working position of the shell 31, and further allow the staff to intuitively observe whether the shell 31 is located at the working position for copper powder removal or maintenance.

[0029] Furthermore, a dust block 122 is provided between the guide rails 12 , and when the outer shell 31 is located on a side of the bottom box 1 close to the through slot 34 , the dust block 122 and the outer shell 31 form a closed space.

[0030] In order to prevent external dust from entering the interior of the shell 31, the dustproof block 122 can prevent external dust from entering the shell 31 when the shell 31 is in the working position for removing copper powder. This is beneficial for further recycling of the collected copper powder and preventing oxidation of the copper powder.

[0031] More preferably, it further comprises a baffle plate 5 detachably connected to the through slot 34 , a groove 314 is provided on the shell 31 , the groove 314 is located at one side of the through slot 34 , and a block 51 matching the groove 314 is provided on the baffle plate 5 .

[0032] In this embodiment, when the block 51 is connected to the groove 314, the baffle 5 separates the through groove 34 into a copper foil input end 321 and a copper foil output end 311; when the block 51 and the groove 314 are disassembled, the copper foil input end 321 and the copper foil output end 311 are in a connected state, which is conducive to the removal of the copper foil from the through groove 34. In particular, when the groove 314 extends to the dust removal plate, the connection between the block 51 and the groove 314 can also prevent the dustproof plate 32 from loosening, thereby improving the integrity of the dustproof plate 32, the outer shell 31 and the baffle 5.

[0033] More preferably, a first handle 322 is further provided on the dustproof plate 32 , and a second handle 36 is provided on a side of the housing 31 away from the through slot 34 .

[0034] The first handle 322 and the second handle 36 facilitate the staff to move the copper powder removal mechanism 3 and remove the dust plate 32 from the housing 31 .

[0035] More preferably, the pressing module 35 includes a pressing roller 351 and a spring 352 , wherein the pressing roller 351 is connected above the dust removal module 33 , and the spring 352 is connected to both sides of the pressing roller 351 .

[0036] In this embodiment, the pressing roller 351 can improve the fit between the pressing roller 351 and the dust removal module 33 through the spring 352 , and facilitate the upward lifting of the pressing roller 351 to facilitate the removal of the copper foil from the inside of the shell 31 .
