Technical Field

[0001] This utility model specifically relates to the field of corona device technology, and more specifically to a corona device with an adjustable structure. Background Technology

[0002] Thin film corona discharge devices are specialized equipment for surface modification of thin film materials such as plastics and paper. Their core function is to change the physical and chemical properties of the film surface through high-voltage corona discharge, solving the problems of "difficult printing, difficult lamination, and difficult bonding". They are widely used in packaging, printing, electronics and other industries.

[0003] When using a corona discharge device, the high-voltage electrode, as the core discharge component, is prone to problems due to factors such as high-voltage environment, material residue, and insulation aging. Common faults can be divided into three categories: "abnormal discharge", "physical damage", and "insulation failure". Therefore, it is necessary to clean the high-voltage electrode with alcohol and remove residual materials. However, most traditional corona discharge devices are fixed with bolts, so it is not possible to adjust the equipment to quickly deal with faults. Utility Model Content

[0004] The purpose of this invention is to provide a corona device with an adjustable structure, which can quickly adjust the top cover to expose the high-voltage electrode, so as to facilitate alcohol cleaning or residue removal of the high-voltage electrode; thereby solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A corona device with an adjustment structure includes a bottom shell, a corona roller located in the middle of the bottom shell, and a high-voltage electrode located above the corona roller; the two ends of the high-voltage electrode are fixed inside a top cover. One end of the top cover is connected to the upper side of one end of the bottom shell via a hinge, and an adjustment component is provided on both sides of the other end of the top cover; the adjustment component includes a cylinder; the middle position of the cylinder is fixed inside the clamp, and the inner side of the clamp is movably connected to the top cover via a rotating shaft. The cylinder rod end of the cylinder is fitted with a fisheye joint, which is movably connected to the cam shaft; the cam shaft is fixed on the outside of the bottom shell.

[0008] As a further technical solution of this utility model, a transition roller is provided on each side of the bottom shell; the two ends of the transition roller are installed in the mounting bracket through bearings; the mounting bracket is inserted into the side ears; there are four side ears, which are welded to the two sides of the bottom shell respectively.

[0009] As a further technical solution of this utility model, the high-voltage electrode is electrically connected to the high-voltage transformer via a wire; the high-voltage transformer is electrically connected to the high-voltage generator.

[0010] As a further technical solution of this utility model, the high-voltage transformer and the high-voltage generator are fixed inside the frame body; a crossbeam is welded to the bottom of the bottom shell; and the crossbeam is fixed on the frame body.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-10 In this embodiment of the present invention, a corona device with an adjustment structure includes a bottom shell 5, a corona roller 13 located in the middle of the bottom shell 5, and a high voltage electrode 11 located above the corona roller 13; the two ends of the high voltage electrode 11 are fixed inside the top cover 6. One end of the top cover 6 is connected to the upper side of one end of the bottom shell 5 via a hinge, and an adjustment component 7 is provided on both sides of the other end of the top cover 6; the adjustment component 7 includes a cylinder 71; the middle position of the cylinder 71 is fixed inside the clamp 72, and the inner side of the clamp 72 is movably connected to the top cover 6 via a rotating shaft. The cylinder rod end of the cylinder 71 is fitted with a fisheye joint 73, which is movably connected to the cam shaft 74; the cam shaft 74 is fixed on the outside of the bottom shell 5.

[0026] If the high-voltage electrode 11 discharges unevenly, it is because ink, film residue, or dust adheres to the surface of the high-voltage electrode 11. It is necessary to stop the machine and wipe the electrode surface with alcohol or special cleaning agent to remove residual impurities.

[0027] When the high-voltage electrode 11 frequently exhibits intense sparks, accompanied by thin-film burn-through, the cause may be sharp protrusions in localized areas of the high-voltage electrode 11, such as edge burrs or adhered metallic impurities. It is necessary to use a file to grind down the electrode edges and remove surface metallic impurities. Therefore, the high-voltage electrode 11 is a core component requiring long-term maintenance and repair.

[0028] By adopting the above technical solution, when the high voltage electrode 11 needs to be repaired, the cylinder rod of the cylinder 71 extends, and with the cooperation of the fisheye joint 73 and the cam shaft 74, the top cover 6 and the bottom shell 5 are flipped, thereby exposing the high voltage electrode 11, which facilitates the repair and maintenance of maintenance personnel. The structure is simple and the adjustment is convenient.

[0029] Since the top cover 6 and the bottom shell 5 rotate relative to each other, their movement trajectory is arc-shaped. The purpose of setting the fisheye joint 73 and the convex shaft 74 is to ensure that the cylinder 71 has an arc-shaped displacement compensation effect.

[0030] In this embodiment, the cylinder 71 is connected to the manual reversing valve 14 via an air pipe; the manual reversing valve 14 is connected to an air source via an air pipe.

[0031] The extension and retraction of cylinder 71 can be achieved by operating the manual directional valve 14, which is very convenient.

[0032] In this embodiment, the bottom shell 5 is provided with two drive rollers 10 and two cleaning rollers 12; the two ends of the drive rollers 10 are installed in conjunction with the bottom shell 5 through bearing seats; gears are installed on both drive rollers 10, and the two gears mesh with each other; one of the two drive rollers 10 is also connected to a motor, and the motor is fixed on the outside of the bottom shell 5.

[0033] By applying the above technical solution, the transmission roller 10 is driven to rotate by a motor. Under the synergistic action of two gears, the two transmission rollers 10 rotate synchronously, thereby completing the transfer of the film. The two cleaning rollers 12 can be electrostatic dust suction rollers or adhesive cleaning rollers. When the film passes through the cleaning rollers 12, the cleaning rollers 12 can effectively adsorb dust on the film to achieve the cleaning purpose and ensure the corona treatment effect of the high voltage electrode 11 on the film.

[0034] In this embodiment, a transition roller 8 is provided on each side of the bottom shell 5; the two ends of the transition roller 8 are installed in the mounting base 20 through bearings; the mounting base 20 is fitted into the side ears 9; there are four side ears 9, which are welded to the two sides of the bottom shell 5 respectively.

[0035] By adopting the above technical solution, the transition roller 8 is set to ensure that the film can smoothly enter between the two cleaning rollers 12, and to avoid the film rubbing against the edge of the bottom shell 5.

[0036] In this embodiment, the high-voltage electrode 11 is electrically connected to the high-voltage transformer 2 via a wire; the high-voltage transformer 2 is electrically connected to the high-voltage generator 3. The high-voltage transformer 2 and the high-voltage generator 3 are fixed inside the frame body 1; a crossbeam 4 is welded to the bottom of the bottom shell 5; the crossbeam 4 is fixed to the frame body 1.

[0037] More specifically, the high-voltage generator is responsible for "signal regulation and power drive," the high-voltage transformer is responsible for "voltage level enhancement," and the high-voltage electrode is responsible for "converting high-voltage electricity into physical discharge," together meeting the "high-frequency, high-voltage, and stable" energy requirements of corona discharge. The three work together to achieve the energy conversion from "low-voltage electricity → high-voltage electricity → corona plasma," ultimately completing the surface modification of the thin film.

[0038] In this embodiment, both ends of the cleaning roller 12 are inserted into the square neck cylinder 15; the square neck cylinder 15 is slidably connected inside the rotating drum 19; the rotating drum 19 is installed by a bearing and a bearing seat 16. A spring 17 is provided between the square neck cylinder 15 and the bearing seat 16; the spring 17 is located inside the rotating cylinder 19.

[0039] By adopting the above technical solution, since the cleaning roller 12 is a consumable, it needs to be replaced frequently. When replacing the cleaning roller 12, first insert one end of the cleaning roller 12 into a square neck cylinder 15, and use the square neck cylinder 15 to compress the spring 17, so that the distance between the two square neck cylinders 15 increases, thereby making it easier to insert the other end of the cleaning roller 12 into another square neck cylinder 15.

[0040] Since sliding shafts are welded to both sides of the square neck cylinder 15, and these sliding shafts are slidably connected in the sliding grooves 18 on both sides of the rotating drum 19, this can play a certain limiting role for the square neck cylinder 15, preventing it from being ejected under the elastic force of the spring 17. Moreover, the rotating drum 19 is installed by the cooperation of the bearing and the bearing seat 16, which can also ensure the normal rotation of the cleaning roller 12, thereby facilitating the dust removal of the film.

[0041] The working principle of this utility model is as follows: the film first passes around the bottom of the transition roller 8, then passes around the inner side of the upper cleaning roller 12, then passes around the lower cleaning roller 12 in an S-shape and exits from the top of the corona roller 13. After being driven by the two transmission rollers 10, it exits from the top of another transition roller 8.

[0042] During the corona discharge process, the high-voltage generator is responsible for "signal regulation and power drive," the high-voltage transformer is responsible for "voltage level enhancement," and the high-voltage electrode is responsible for "converting high-voltage electricity into physical discharge," together meeting the "high-frequency, high-voltage, and stable" energy requirements of corona discharge. The three work together to achieve the energy conversion from "low-voltage electricity → high-voltage electricity → corona plasma," ultimately completing the surface modification of the thin film.

[0043] When the high-voltage electrode 11 needs maintenance, the cylinder rod of cylinder 71 extends, and with the cooperation of the fisheye joint 73 and the cam shaft 74, the top cover 6 and the bottom shell 5 are flipped, thereby exposing the high-voltage electrode 11. This facilitates maintenance and repair by maintenance personnel. The structure is simple and easy to adjust. Since the top cover 6 and the bottom shell 5 rotate relative to each other, their movement trajectory is arc-shaped. The purpose of setting the fisheye joint 73 and the convex shaft 74 is to ensure that the cylinder 71 has an arc-shaped displacement compensation effect.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
