[0038] Refer to Figure 1 、 Figure 2 and Figure 5, an embodiment of the present utility model shows an electrode bracket 100, including a substrate 1. On both sides of the substrate 1 in its width direction, rib plates 2 are provided. A limiting groove 3 for at least partial insertion of an insulating slot plate 600 is formed between the substrate 1 and the rib plates 2 on its two sides. The substrate 1 and the rib plates 2 on its two sides are of an integral structure; a plurality of exhaust holes 11 penetrating through the substrate 1 in the thickness direction of the substrate 1 are provided on the substrate 1. A plurality of connecting parts 12 for connecting the insulating slot plate 600 are further provided on the substrate 1. The plurality of connecting parts 12 are arranged at intervals along the length direction of the substrate 1. Each connecting part 12 includes at least one first connecting hole 1211, and the first connecting hole 121 penetrates through the substrate 1 in the thickness direction; a supporting part 21 for abutting against the insulating slot plate 600 is formed on the side of the rib plate 2 away from the substrate 1.

[0039] Specifically, the electrode bracket 100 of this embodiment is formed by a substrate 1 and two rib plates 2 into a trough-shaped structure with a U-shaped cross-section, which greatly improves the tensile strength of its overall structure, facilitates maintaining structural stability under high-power working conditions, and avoids deformation; at the same time, exhaust holes 11 are arranged on the substrate 1, which can discharge ozone gas and hot air generated during the corona process, avoid the working temperature being too high during corona treatment, and maintain the good operation of high-speed production; and by providing rib plates 2 that can abut against and support the insulating slot plate 600, the stable clamping of the insulating slot plate 600 on the discharge electrode 700 in high-power working conditions can be maintained, and the overall structure of the corona discharge rack can be kept stable.

[0040] Among them, as Figure 1 and Figure 2 shown, one rib plate can be respectively provided on both sides of the substrate in its width direction, or multiple rib plates can be respectively provided. For example: two rib plates are respectively provided on both sides of the substrate, and the four rib plates are paired in pairs, and still can form the limiting groove.

[0041] In addition, to facilitate further understanding of the structural advantages of the electrode bracket 100 of the present application, this embodiment provides a corona discharge rack containing the electrode bracket 100 of the present application for comparison with the corona discharge rack in the prior art (such as the Chinese patent with the publication number CN220635134U):

[0042] Refer to Figures 3 - 8, which shows a corona discharge rack containing the electrode support 100 of the present application, including the electrode support 100 of the present application, and further including two support plates 200 and a corona roller 400 arranged between the two support plates 200. Both ends of the electrode support 100 are fixedly connected with moving seats 300, and the moving seats 300 are horizontally movably arranged on the support plates 200 through a slide rail assembly (not marked in the figure). A plurality of insulating slot plates 600 are installed in the limiting slots 3 of the electrode support 100, and a number of discharge electrodes 700 are installed on the insulating slot plates 600; an exhaust duct 500 is arranged on one side of the electrode support 100 away from the insulating slot plate 600.

[0043] Among them, as Figure 5 and Figure 6 shown, the electrode support 100 of the present application is formed by a base plate 1 and two rib plates 2 into an overall U-shaped groove structure, while the electrode support in the prior art (CN220635134U) is in an L-shaped structure; in this embodiment, a part of the insulating slot plate 600 is inserted into the limiting slot 3, and a supporting step portion 610 is formed between the part of the insulating slot plate 600 inserted into the limiting slot 3 and the part located outside the limiting slot 3; and the supporting portion 21 on the rib plate 2 of the electrode support 100 abuts against the supporting step portion 610, and the insulating slot plate 600 is supported by the two rib plates 2; at the same time, the first connection hole 121 on the base plate 1 is bolt-connected to the insulating slot plate 600, which can ensure the stable position of the insulating slot plate 600 in the limiting slot 3.

[0044] In this embodiment, each connecting portion 12 includes at least three first connection holes 121, and the at least three first connection holes 121 are arranged along the width direction of the base plate 1 to further ensure the firm connection between the base plate 1 and the insulating slot plate 600.

[0045] Furthermore, as Figure 6 shown, the inner side surface of the rib plate 2 is perpendicular to the inner side surface of the base plate 1, and the distance between the inner side surfaces of the two rib plates 2 is equal to the width of the part of the insulating slot plate 600 inserted into the limiting slot 3. Thus, compared with the prior art, in this embodiment, the two rib plates 2 limit the part of the insulating slot plate 600 inserted into the limiting slot 3, which can ensure that the insulating slot plate 600 will not shake or deform in the width direction of the limiting slot 3.

[0046] As Figure 2 , Figure 4 and Figure 8As shown, mounting holes 13 are respectively provided at both ends of the substrate 1 along the length direction, and the mounting holes 13 are connected to the moving seat 300 through bolts; wherein, the mounting holes 13 are strip-shaped holes, and the length direction of the mounting holes 13 is arranged along the width direction of the substrate 1. In this way, the vertical mounting position of the substrate 1 on the moving seat 300 can be adjusted through the mounting holes 13, and the moving seat 300 itself can adjust the lateral position on the support plate 200 through the slide rail assembly, so as to realize the adjustment of the discharge gap between the discharge electrode 700 and the corona roller 400.

[0047] Further, as Figure 1 , Figure 5 and Figure 7 shown, the exhaust holes 11 are strip-shaped holes, the length direction of the exhaust holes 11 is arranged along the length direction of the substrate 1, and the exhaust holes 11 are arranged at the edge position of the inner side surface of the substrate 1. Among them, the exhaust holes 11 on the substrate 1 are communicated with the exhaust pipe 500, and the exhaust pipe 500 can extract air. The ozone gas and hot air generated during the corona process will enter the limiting groove 3, and then enter the exhaust pipe 500 through the exhaust holes 11 on the substrate 1, and finally be discharged; it can avoid the working temperature being too high during the corona treatment and maintain the good operation of high-speed production. The strip shape of the exhaust holes 11 in this embodiment has a wide exhaust area, which can effectively reduce the wind resistance, and at the same time improve the wind speed and air volume; the setting position of the exhaust holes 11 on the substrate 1 can reduce the influence of opening the exhaust holes 11 on the structural strength of the substrate 1.

[0048] In the above solution, to further improve the exhaust efficiency, as Figure 5 , Figure 6 and Figure 8 shown, the back of the substrate 1 abuts against the exhaust pipe 500, and the exhaust holes 11 are communicated with the exhaust pipe 500; compared with the prior art, this embodiment can make there be no large gap between the substrate 1 and the exhaust pipe 500, so that the suction force of the exhaust pipe 500 is basically released through the exhaust holes 11 on the substrate 1, improving the suction efficiency and wind speed.

[0049] In the above solution, to facilitate the connection of the cover plate 800, a second connection hole 22 is further provided on the rib plate 2 in this embodiment. The second connection hole 22 penetrates along the thickness direction of the rib plate 2, and the second connection hole 22 can be connected to the cover plate 800 through bolts. Among them, the function of the cover plate 800 can refer to the prior art (CN220635134U).

[0050] In the above solution, as Figure 8As shown, positioning steps 23 are respectively provided at both ends of the rib plate 2 along the length direction. The insulating slot plate 600 at the edge position is flush with the positioning steps 23, so that an installation space for installing the high-voltage junction box 900 can be formed between the insulating slot plate 600 at the edge position and the end edge position of the substrate 1, so as to realize the energization of the discharge electrode 700.

[0051] In the above solution, the substrate 1 and the two rib plates 2 are made of aluminum, so that the electrode support 100 of the present application has good oxidation and corrosion resistance, and is prevented from being oxidized and corroded by a large amount of ozone gas generated during the corona process; and the electrode support 100 is light in weight, low in cost and has excellent heat dissipation effect. Combined with the structure of the exhaust holes 11 provided on the substrate 1, the working temperature can be effectively guaranteed to be stable, which is conducive to realizing the long-term stable operation of high-speed production.

[0052] It should be noted that the description in the above embodiments focuses on the structural characteristics of the electrode support 100 and the connection relationship between the components in the corona discharge frame and the electrode support 100. For the specific structures and working principles of the components such as the support plate 200, the moving seat 300, the corona roller 400, the insulating slot plate 600, the discharge electrode 700, etc. in the corona discharge frame, reference can be made to the prior art (CN220635134U), which will not be elaborated here.

[0053] In summary, the embodiment of the present utility model provides an electrode support and a corona discharge frame containing the same. The electrode support 100 forms a trough-shaped structure with a U-shaped cross-section through the substrate 1 and two rib plates 2 of an integrated structure, so that the tensile strength of its overall structure is greatly improved, which is convenient to maintain the structural stability under high-power working conditions and avoid deformation; at the same time, the substrate 1 is provided with exhaust holes 11, which can discharge the ozone gas and hot air generated during the corona process, avoid the working temperature being too high during corona treatment, and maintain the good operation of high-speed production; in this corona discharge frame, the two sides of the insulating slot plate 600 are supported by the rib plates 2 on the electrode support 100, so as to maintain the stable clamping of the discharge electrode 700 by the insulating slot plate 600 under high-power working conditions and maintain the overall structural stability of the corona discharge frame.

[0054] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
