Description

Technical Field

[0001] The utility model relates to the technical field of corona machine electrodes, in particular to a stainless steel double-headed water drop-shaped electrode for a corona machine. Background Art

[0002] The corona machine is composed of electrodes, high potentiometers and roll guide rollers. When the voltage exceeds the ionization resistance of the air gap of 1-2mm, continuous discharge will occur, which is used for surface pretreatment of silicone rubber, plastic and other materials.

[0003] In the prior art, the electrodes of the corona machine are mostly copper electrodes, aluminum electrodes, ceramic electrodes or stainless steel cylindrical electrodes. Due to their structure such as sawtooth or plane or cylindrical shape, when in use, copper electrodes and aluminum electrodes, due to their good thermal conductivity, the electrodes themselves are prone to thermal effects during the discharge process, and are oxidized by the generation of ozone, generating black or gray powder at the electrodes, which is not conducive to the high-quality dust-free requirements. Ceramic electrodes basically need to be kept in a very clean state and used in a dry state to exert the best characteristics within a distance of 1.5mm from the treated object. In this case, special attention should be paid to maintenance and maintenance to maintain this state, otherwise there will often be undesirable phenomena such as creepage, electrode overheating or electrode breakage. Stainless steel electrodes are basically made of 204 or 304 materials. The acid resistance (ozone O3) effect during the corona process is less than ideal, and there is often a phenomenon of burnt carbon yellowing. Under long-term operation, it is necessary to clean and brush frequently to remove carbonization to maintain the best discharge state. Utility Model Content

[0004] The utility model aims to provide a stainless steel double-headed water drop-shaped electrode for a corona machine to solve the problems raised by the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a stainless steel double-headed teardrop-shaped electrode for a corona machine, comprising a middle rod, the upper and lower ends of the middle rod are fixedly connected with end caps, the upper end of the end cap is provided with a dome area, and rounded transition areas are provided between the two ends of the dome area and the sides of the middle rod. The middle rod and the end caps are made of 316 stainless steel and are produced by high-pressure drawing, pulling and casting. In this way, the generation of edge burrs can be reduced to improve the processing efficiency of the processed objects, while improving the heat resistance and deformation resistance. The two end caps are symmetrically designed, and the dome area and the rounded transition area are set to form the end caps into a teardrop shape. When in use, the fixed seat and the high-voltage line contact end used in conjunction with it are both slot-type, which can greatly reduce the occurrence of wiring labor problems.

[0006] Compared with the prior art, the advantages and positive effects of the utility model are:

[0007] In the utility model, the treatment effect of the dispersion energy on the surface of the treated object is increased through the design of two ends, so that the cooling exchange is more effectively carried out through the air medium, and the long-term high-voltage and high-frequency continuous corona that the general electrode cannot withstand can be implemented, or the high-distance three-dimensional corona of the treated object can be implemented. At the same time, the 316 stainless steel material is adopted, which can better withstand the high temperature and highly corrosive ozone generated by the high-voltage and high-frequency electrodes than the existing metal electrodes, and can not produce oxidation blackening, mutation, and oxidation powder. In addition, through the symmetrical arrangement of the two ends, one end is inevitably damaged in long-term use, and foreign matter is attached to affect the surface treatment effect. It can be used immediately by just pulling it out and swapping it, and maintenance and replacement are simpler. BRIEF DESCRIPTION OF THE DRAWINGS
