Description

Technical Field

[0001] This application relates to the field of corona treatment machine technology, and in particular to a self-cleaning corona treatment machine. Background Technology

[0002] Corona treatment machines are widely used in the surface modification of materials such as plastics, paper, and metals. They enhance the surface energy of materials through corona discharge, thereby improving their adhesion to coatings, inks, and other materials. However, during the operation of traditional corona treatment machines, impurities such as ozone and dust generated by corona discharge can easily adhere to the surface of key components such as the corona plate. This not only affects the corona treatment effect and quality stability but also leads to a decline in equipment performance and a shortened lifespan. Furthermore, if the heat generated during equipment operation cannot be dissipated in time, it can also cause overheating failures, affecting the normal use of the equipment and production efficiency.

[0003] A search revealed Chinese Patent Publication No. CN113561464B, which discloses an adaptive corona treatment machine. The machine includes a body with a support frame inside. A cleaning device is located at the upper end of the support frame, and the cleaning device includes an air blowing mechanism. Support members are located at both ends of the air blowing mechanism, and the cleaning mechanism is located at the lower angle of the air blowing mechanism. This invention utilizes a geared motor to drive a cleaning roller to rotate. The cleaning roller contacts the support frame, allowing dust to adhere to the surface of the substrate through rotation, preventing dust from affecting normal corona treatment. When the cleaning roller rotates, a limiting plate and a retaining bead contact the support frame. This allows the limiting plate to be deflected and retracted into the slot by the retaining bead. The limiting plate, under pressure, contacts an auxiliary plate, preventing damage from excessive deflection and assisting in the repositioning of the limiting plate, facilitating subsequent deflection and contact with the support frame.

[0004] The aforementioned patent specification mentions that "the blowing mechanism includes an airbag, the airbag is fixedly connected to the surface of the machine body, an elastic element is provided inside the airbag, a connecting plate is provided at the lower end of the airbag, seven air tubes are connected to the lower end of the airbag, and two connecting rods are fixedly connected to the surface of the connecting plate, and each of the two connecting rods is respectively connected to a support member." However, some cleaning methods cannot quickly remove surface dust. In response to the aforementioned related technologies, a self-cleaning corona treatment machine is proposed to solve the above problems. Utility Model Content

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Before corona treatment, once the rotating motor starts running, it drives the connecting rotating plate to rotate via the connecting rotating rod. The connecting support column then drives the connecting rotating column to rotate, providing stable support. As the connecting rotating column rotates, it causes the connecting sliding block to slide left and right, which in turn causes the cleaning brush to move back and forth, thoroughly cleaning the material surface. This effectively removes dust and impurities from the material surface, preventing foreign matter from weakening the corona treatment effect and ensuring the uniformity of material surface activation. At the same time, the mechanical transmission structure is stable, improving production efficiency and extending the service life of the corona treatment equipment.

[0024] 2. Turning on the second cooling fan accelerates airflow, driving air circulation between the second and first cooling fins, quickly removing heat. Turning on the first cooling fan further exhausts heat from the first cooling fin. The copper pipe connects the two fins in series, achieving efficient heat conduction and relay transfer thanks to its excellent thermal conductivity. Compared to single-stage cooling, this improves efficiency, effectively reducing the temperature of core components, preventing performance degradation or malfunctions due to overheating, and extending the equipment's lifespan.

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0031] Example: A self-cleaning corona treatment machine, referring to... Figure 1 , Figure 2 The system includes a support frame 1, which serves as the basic framework of the corona treatment machine. The support frame 1 provides a stable mounting base for components such as the cleaning mechanism 2, heat dissipation mechanism 3, rotating motor 4, protective housing 5, and corona plate 6. The cleaning mechanism 2 is fixedly connected to the outside of the support frame 1, and multiple heat dissipation mechanisms 3 are fixedly connected to the inside of the support frame 1. The cleaning mechanism 2 includes a drive assembly 21 for driving. After the rotating motor 211 is energized, its drive end drives the connecting rotating rod 212 to rotate at high speed. A connecting rotating plate 22 is fixedly connected to the outside of the drive assembly 21, and the drive assembly 21 is externally fixedly connected to the outside of the support frame 1. A connecting support column 23 is fixedly connected to the outside of the connecting rotating plate 22. The connecting rotating plate 22 rotates around the support frame 1 under the drive of the connecting rotating rod 212, and the connecting support column 23 fixed on it moves accordingly. A connecting rotating column 24 is rotatably connected to the outside of the connecting support column 23. A supporting rotating column 25 is rotatably connected to the inner side of the connecting rotating column 24, that is, the end away from the connecting support column 23. The connecting rotating column 24 rotates under the drive of the connecting support column 23. The supporting rotating column 25 is rotatably connected to its inner side, providing stable support for the connecting rotating column 24, ensuring that it does not deviate or shake during rotation, and ensuring the stability of the cleaning movement.

[0032] A connecting sliding block 26 is fixedly connected to the external side of the supporting rotating column 25. A cleaning brush 27 is fixedly connected to the external side of the connecting sliding block 26. When the connecting rotating column 24 rotates, the supporting rotating column 25 drives the connecting sliding block 26 to slide left and right on the supporting frame 1, thereby causing the cleaning brush 27 fixed on the connecting sliding block 26 to reciprocate back and forth, cleaning the material surface, removing dust and impurities, and improving the corona treatment effect. The drive assembly 21 includes a rotating motor 211. A connecting rotating rod 212 is fixedly connected to the drive end of the rotating motor 211. One end of the connecting rotating rod 212 is fixed to the rotating motor 211, and the other end is connected to the connecting rotating rod 212. The plates 22 are connected to provide a power source for cleaning operations. The external of the rotating motor 211 is fixedly connected to the outside of the support frame 1. The external of the connecting rotating rod 212 is rotatably connected to the outside of the support frame 1. The external end of the connecting rotating rod 212, i.e. the end away from the rotating motor 211, is fixedly connected to the inside of the connecting rotating plate 22. The external of the connecting rotating plate 22 is rotatably connected to the outside of the support frame 1. The external of the connecting rotating column 24 is rotatably connected to the outside of the support frame 1. The external of the supporting rotating column 25 and the connecting sliding block 26 is slidably connected to the outside of the support frame 1. The external of the cleaning brush 27 is slidably connected to the outside of the support frame 1.

[0033] Specifically, in cleaning mechanism 2, the rotating motor 211 drives the connecting rotating rod 212 to rotate, which in turn drives the connecting rotating plate 22, the connecting support column 23, and the connecting rotating column 24 to move in tandem. The support rotating column 25 ensures rotational stability, and the connecting sliding block 26 drives the cleaning brush 27 to sweep the material surface back and forth to remove dust and impurities. This prevents foreign objects on the material surface from affecting the corona effect and ensures that the treated material surface can meet the standards uniformly. The mechanical transmission structure is precisely designed, which reduces wear rate, extends equipment maintenance cycle, reduces production costs, and significantly improves production efficiency.

[0034] Reference Figure 1 , Figure 3 and Figure 4The heat dissipation mechanism 3 includes a rotating cooling fan 35, with a heat dissipation fin 34 fixedly connected to the outside of the rotating cooling fan 35. After receiving the heat transferred by the connecting copper pipe 32, the heat dissipation fin 34 increases the heat dissipation area and improves the heat dissipation efficiency. The connecting copper pipe 32 is fixedly connected inside the heat dissipation fin 34. As a key component for heat transfer, the connecting copper pipe 32 has good thermal conductivity and can quickly transfer the heat on the first heat dissipation fin 33 to the second heat dissipation fin 34. The first heat dissipation fin 33 is fixedly connected to the outside of the connecting copper pipe 32, i.e., the end away from the second heat dissipation fin 34. A rotating cooling fan 31 is fixedly connected to the outside of the first heat dissipation fin 33. After being powered on, the rotating cooling fan 31 runs at high speed, accelerates the airflow, and quickly blows the heat away from the first heat dissipation fin 33. The first heat dissipation fin 33 increases the heat dissipation area and transfers the heat to the air through thermal conduction. It is mainly used for preliminary heat dissipation of key heat-generating parts of the equipment.

[0035] The external fixed connection of the rotating cooling fan 31 is to the inner side of the support frame 1. The external fixed connection of the cooling fin 33 is to the inner side of the support frame 1. The internal fixed connection of the support frame 1 is to the rotating motor 4. The external fixed connection of the rotating motor 4 is to the protective shell 5 to prevent the motor from being corroded by dust and moisture, and to ensure the safe and stable operation of the equipment. The external fixed connection of the protective shell 5 is to the outside of the support frame 1. The top of the support frame 1 is fixedly connected to the corona plate 6, which is the core functional component of the corona treatment machine.

[0036] Specifically, in the heat dissipation mechanism 3, the rotating cooling fan 31 works in conjunction with the heat dissipation fins 33, and the copper pipe 32, with its good thermal conductivity, efficiently transfers heat to the heat dissipation fins 34. The heat dissipation fins 34 and the rotating cooling fan 35 further accelerate heat dissipation, ensuring stable equipment temperature. The protective shell 5 of the rotating motor 4 is dustproof and waterproof. The corona plate 6 achieves surface treatment of the material, significantly reducing the risk of equipment overheating, extending service life, ensuring stable corona treatment effect, and the protective design improves equipment reliability, reduces maintenance costs, and provides a guarantee for efficient production.

[0037] The implementation principle of this application embodiment is as follows: When it is necessary to clean the material that needs to be corona-electrode, the operation of the rotating motor 211 drives the rotation of the connecting rotating rod 212, which in turn drives the rotation of the connecting rotating plate 22, which in turn drives the rotation of the connecting support column 23, thereby driving the rotation of the connecting rotating column 24. At the same time, the support rotating column 25 provides support for the rotation of the connecting rotating column 24, ensuring the normal operation of the connecting rotating column 24. This causes the connecting sliding block 26 to slide left and right, which in turn causes the cleaning brush 27 to slide back and forth, thereby reducing dust on the material and reducing the problem of weakened corona-electrode effect due to dust.

[0038] When internal heat dissipation is required, the operation of cooling fan 2 35 is first turned to increase the airflow rate inside cooling fins 2 34 and fin 1 33, thereby increasing the heat dissipation effect. At the same time, cooling fan 1 31 is turned to expel the heat inside cooling fin 1 33 again, ensuring that the heat is quickly dissipated. Meanwhile, copper pipe 32 is connected to cooling fins 2 34 and fin 1 33 to increase heat dissipation efficiency.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
