Description

Technical Field

[0001] This utility model relates to the field of electrode assembly technology, specifically to an electrode assembly and a corona treatment machine. Background Technology

[0002] A corona treatment machine is a device that increases the surface energy of materials through high-voltage discharge. It is mainly used to improve the printing and coating adhesion of non-polar materials such as plastic films and silicone rubber. The corona treatment machine generates high-frequency high voltage (approximately 15kV, 20kHz) after rectifying and inverting three-phase AC power. During discharge, it produces active particles and ozone, which oxidize the material surface to form polar groups, thereby increasing the surface energy.

[0003] Corona treatment machines discharge through electrode assemblies. Currently, electrode assemblies consist of a mounting base fixed together and multiple electrode plates. This type of assembly has the following problems: First, because the mounting base and electrode plates are fixed together, cleaning is inconvenient; second, it is difficult to adjust the number of electrode plates according to actual needs. The number of electrode plates needs to be adjusted in the following scenarios: 1. Electric field distribution and processing uniformity: Increasing the number of electrode plates expands the electric field's effective area, making the corona discharge on the surface of the material to be treated (such as thin films and sheets) more uniform. If there are too few electrode plates, the discharge intensity in concentrated areas of the electric field may be too high, causing localized overheating or material breakdown. Increasing the number of electrode plates can disperse the electric field energy and improve processing stability. 2. Output power and processing efficiency: The more electrode plates there are, the more corona discharges are generated per unit time, thereby increasing the overall power density, suitable for material processing on high-speed production lines. By adjusting the number of electrode plates and the operating frequency (usually 15~30kHz), energy consumption can be reduced while ensuring processing effectiveness. The current electrode assembly is not convenient for adjusting the number of electrodes, so there is an urgent need for an electrode assembly and a corona treatment machine to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the deficiencies and shortcomings of the existing technology by providing an electrode assembly and a corona treatment machine. The mounting base and the electrode are detachably connected, which facilitates the installation and removal of the mounting base and the electrode, makes it easy to clean the electrode, slows down the oxidation of the electrode, and extends the service life of the electrode. In addition, different numbers of electrode plates can be installed according to actual needs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an electrode plate assembly, comprising: a mounting base and a plurality of electrode plates that are evenly distributed and detachably connected to the mounting base. There are two mounting bases, each of which has a plurality of evenly distributed first mounting holes, and the first mounting holes on the two mounting bases correspond one-to-one. The electrode plates are detachably connected to the two corresponding first mounting holes.

[0006] Optionally, the first mounting hole includes circular holes and strip holes that are distributed internally and externally and communicate with each other. The width of the strip hole is smaller than the diameter of the circular hole, and the electrode sheet is embedded in the corresponding two first mounting holes.

[0007] Optionally, the end of the mounting base near the first mounting hole has a concave arc surface, and the electrode sheet is perpendicular to the arc surface.

[0008] Optionally, two mounting bases extend from each end of the electrode sheet.

[0009] Optionally, both ends of the electrode sheet are in the shape of round rods.

[0010] Optionally, the mounting base has multiple second mounting holes at the end away from the electrode sheet.

[0011] Optionally, the mounting base is an L-shaped plate.

[0012] Optionally, the mounting base has concave curved surfaces on both sides.

[0013] This utility model also provides a corona treatment machine, including the above-mentioned electrode assembly.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: The mounting base and electrode plates are detachably connected, which facilitates the installation and removal of the mounting base and electrode plates, makes it easy to clean the electrode plates, slows down the oxidation of the electrode plates, and extends the service life of the electrode plates; in addition, different numbers of electrode plates can be installed according to actual needs.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0020] This embodiment relates to an electrode assembly applied in a corona treatment machine, such as... Figure 1-3 As shown, the device includes a mounting base 1 and several electrode plates 2 that are evenly distributed and detachably connected (e.g., by embedding, snap-fitting, or other detachable connection methods) to the mounting base 1. Two mounting bases 1 extend from each end of the electrode plate 2. Each mounting base 1 has several evenly distributed first mounting holes 11, and these first mounting holes 11 correspond one-to-one. The electrode plates 2 are detachably connected (e.g., by embedding, snap-fitting, or other detachable connection methods) to the two corresponding first mounting holes 11. Several electrode plates 2 are mounted on the corona treatment machine via the two mounting bases 1. The detachable connection between the mounting base 1 and the electrode plates 2 facilitates installation and removal, makes cleaning the electrode plates 2 easier, slows down oxidation, and extends their service life. Furthermore, different numbers of electrode plates 2 can be installed according to actual needs. Multiple second mounting holes 12 are provided at the end of the mounting base 1 furthest from the electrode plates 2, allowing workers to use bolts to install the mounting base 1 onto the corona treatment machine.

[0021] Furthermore, such as Figure 3 As shown, the first mounting hole 11 includes a circular hole 111 and a strip hole 112 that are distributed internally and externally and communicate with each other. The width of the strip hole 112 is smaller than the diameter of the circular hole 111. The electrode piece 2 is embedded in the corresponding two first mounting holes 11. This design is to prevent the electrode piece 2 installed in the first mounting hole 11 from falling out and to keep it within the first mounting hole 11. During installation, the electrode piece 2 is inserted into the first mounting hole 11 from the side of one mounting base 1 and then into the first mounting hole 11 of another mounting base 1. There is a certain friction between the electrode piece 2 and the first mounting hole 11, which can prevent the electrode piece 2 from sliding within the first mounting hole 11. In use, the electrode piece 2 faces upward or downward and is stably positioned on the mounting base 1 by its own weight.

[0022] like Figure 1-3 As shown, the end of the mounting base 1 near the first mounting hole 11 is a concave arc surface, and the electrode plate 2 is perpendicular to the arc surface. This design is conducive to the uniform discharge of the electrode plate 2.

[0023] To further enhance the uniformity of discharge, both ends of electrode 2 are made into round rods.

[0024] like Figure 1 As shown, mounting base 1 is an L-shaped plate, which has a simple structure and is easy to manufacture.

[0025] Furthermore, because the electrode sheet 2 is relatively lightweight, the two sides of the mounting base 1 are designed as concave curved surfaces to reduce the amount of material used in the mounting base 1.

[0026] This utility model also provides a corona treatment machine, including the above-mentioned electrode plate assembly. Since the corona treatment machine includes the electrode plate assembly, the corona treatment machine also possesses the advantages and effects of the electrode plate assembly, which will not be repeated here.

[0027] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
