Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plasma surface treatment, and particularly relates to a plasma treatment structure and equipment with suspended discharge. Background Art
[0002] A plasma surface treatment device is a device that uses plasma technology to clean the dirt on the surface of materials, change the properties of the material surface, improve the quality and service life of materials, and is widely applicable to various occasions and materials, such as aluminum foil, copper foil or other conductive materials.
[0003] And the principle of plasma surface treatment technology is as follows: First, high-voltage discharge is carried out through a high-frequency voltage waveform to generate plasma on the material surface; subsequently, under the action of the plasma, oxidation, degradation and other mechanisms will occur on the material surface, and at the same time, the activity of ions will be changed, thereby changing the structure and morphology of the surface and surface complexes; finally, a new material layer is formed on the material surface, and specific properties are imparted to the material surface through this material layer, such as enhancing wear resistance, corrosion resistance or improving surface adhesion, etc.
[0004] The existing discharge structure of the plasma surface treatment device is as follows: First, multiple groups of positive discharge electrodes and negative discharge rollers are sequentially arranged at intervals in the discharge area, and then the material placed on the feeding roller is passed through the positive discharge electrodes and negative discharge rollers arranged in the discharge area; at this time, during the discharge process, the material contacts the negative discharge roller, so as to perform surface treatment on the material passing between the positive discharge electrode and the negative discharge roller. However, with the increasing demand for the surface treatment speed of materials in the industrial community, the movement speed of high-energy particles in the existing discharge structure and their interaction efficiency with the material surface gradually show limitations. This bottleneck restricts the further improvement of the overall treatment rate and is difficult to meet the urgent market demand for high-efficiency and high-quality surface treatment. Summary of the Utility Model
[0005] The technical problem solved by the utility model is to provide a plasma treatment structure and equipment with suspended discharge that can improve the movement speed of high-energy particles in the plasma, so as to improve the treatment efficiency of the plasma surface treatment device, shorten the material treatment time, and respond to the urgent market demand for high-efficiency and high-quality surface treatment technology.
[0006] To solve the above technical problems, on the one hand, the present utility model provides a plasma treatment structure with suspended discharge, which includes a high-voltage generator. The positive electrode of the high-voltage generator is connected in parallel with a first discharge positive electrode and a second discharge positive electrode through wires. The first discharge positive electrode and the second discharge positive electrode are arranged oppositely, and a material conveying channel is arranged between the first discharge positive electrode and the second discharge positive electrode. The material to be treated in the material conveying channel is grounded. At this time, when using the plasma treatment structure with suspended discharge provided by the present utility model to perform surface treatment on the material to be treated with conductive properties, the material to be treated serves as the negative electrode, and the first discharge positive electrode and the second discharge positive electrode on both sides of the material to be treated serve as two positive electrodes. A high-low potential will be formed between the material to be treated and the two discharge positive electrodes, and plasma will be generated to treat the two surfaces of the material to be treated. Moreover, compared with the traditional discharge structure, in this special discharge structure of the present utility model, the movement speed of high-energy particles in the plasma will be faster, thereby improving the processing efficiency of the plasma surface treatment equipment, shortening the material processing time, and meeting the urgent market demand for high-efficiency and high-quality surface treatment technology.
[0007] Furthermore, there is a first discharge gap between the first discharge positive electrode and the material to be treated, and a second discharge gap between the second discharge positive electrode and the material to be treated. By means of the first discharge gap and the second discharge gap, it is ensured that neither the first discharge positive electrode nor the second discharge positive electrode is in contact with the material to be treated, so that both sides of the material to be treated can be treated simultaneously, thereby improving the efficiency and treatment effect.
[0008] Furthermore, the high-voltage generator is an AC high-voltage generator.
[0009] On the other hand, the present utility model provides a plasma treatment device with suspended discharge, which includes a frame and a feeding roller. The above-mentioned plasma treatment structure with suspended discharge is installed on the frame.
[0010] Furthermore, the feeding roller is connected with a ground wire and can be grounded through this ground wire to ensure that the material to be treated is in a grounded state.
[0011] As can be seen from the above technical solutions, the present utility model has the following advantages: when using the plasma treatment structure of suspended discharge provided by the present utility model to perform surface treatment on a material to be treated with electrical conductivity, the material to be treated serves as the negative electrode, and the discharge positive electrode one and the discharge positive electrode two on both sides of the material to be treated serve as two positive electrodes. A high-low potential will be formed between the material to be treated and the two discharge positive electrodes, and plasma will be generated to treat the two surfaces of the material to be treated; moreover, compared with the traditional discharge structure, in this special discharge structure of the present utility model, the movement speed of high-energy particles in the plasma will be faster, thereby improving the treatment efficiency of the plasma surface treatment equipment and shortening the material treatment time; at the same time, the discharge width of this discharge structure will be processed according to the width of the material, improving the surface treatment efficiency and saving energy, and thus responding to the urgent market demand for high-efficiency and high-quality surface treatment technologies.
