Description

Technical Field

[0001] This utility model belongs to the field of screen printing mesh production technology, and in particular relates to an electrode system for a corona treatment machine. Background Technology

[0002] Corona treatment of screen printing mesh can improve ink adhesion, ink flow, printability (abrasion resistance), printing accuracy, and reduce printing tension requirements. Current corona treatment devices mainly consist of a power supply module, discharge electrode, and ground electrode. The ground electrode is a roller electrode, and the bottom surface of the discharge electrode has an arc-shaped discharge rod for matching the roller electrode.

[0003] Current discharge electrodes typically employ a monolithic electrode design, where one or more parallel elongated electrodes cover the entire processing width. This leads to the following problems:

[0004] 1. Poor flexibility, unable to adapt to materials of different widths, leading to energy waste or uneven processing;

[0005] 2. Maintenance is difficult; once damage occurs, the entire electrode needs to be replaced, which is costly and results in long downtime.

[0006] 3. Low control precision, unable to perform differentiated treatment for different areas of the material, such as the edges and the center. Summary of the Invention

[0007] The purpose of this invention is to provide an electrode system for a corona treatment machine. By designing an assemblable modular discharge electrode, parameters can be adjusted for the material edge and center areas, avoiding the edge effect (insufficient or excessive edge treatment) of traditional designs, improving processing uniformity, and activating modules of corresponding widths according to the material width, thus improving energy efficiency. It is also suitable for processing materials of different widths and materials of different raw materials, thus expanding its applicability.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is an electrode system for a corona treatment machine, including a discharge electrode and a grounding electrode;

Magnets are embedded and fixed on the front and rear sides of both the main electrode box and the auxiliary electrode box.

[0013] Mounting seats are fixed on the front and rear sides of both sides of the main electrode box. The main electrode box is fixed in the middle between the two crossbeams. The mounting seats are connected to the crossbeams by fasteners.

[0014] The auxiliary electrode boxes are symmetrically arranged in several groups on the front and rear sides of the main electrode box. The front and rear sides of both sides of the auxiliary electrode box are fixed with inverted L-shaped supports. The bottom surface of the horizontal side and the outer side of the vertical side of the supports are fixed with ball bearings.

[0015] The auxiliary electrode box is located between the two crossbeams and is slidably engaged with the crossbeams by a support and ball bearings. The auxiliary electrode box is magnetically connected to the main electrode box and to adjacent auxiliary electrode boxes by magnets.

[0016] Furthermore, a wire trough with an open top surface is fixed to the outer side of one of the crossbeams, and a plurality of wires are provided in the wire trough, with each end of the plurality of wires connected to a high-frequency high-voltage power supply.

[0017] Furthermore, the main electrode box is electrically connected to a circuit, and the remaining circuits are connected to two quick connectors via branches. Several sets of auxiliary electrode boxes are electrically connected to two quick connectors on the remaining circuits, respectively.

[0018] Furthermore, the grounding electrode is a roller electrode structure, the grounding electrode is located directly below the lifting frame, and the grounding electrode is connected to the ground wire.

[0019] Furthermore, when the bottom surfaces of the main electrode box and the auxiliary electrode box are concentric with the grounding electrode, the distance between the plurality of discharge rods and the peripheral surface of the grounding electrode is consistent.

[0020] Furthermore, handles are fixed to both the front and rear sides of the top of the secondary electrode box.

[0021] This utility model has the following beneficial effects:

[0022] This invention, through the design of an assemblable modular discharge electrode, allows for parameter adjustment for the material edge and center regions, avoiding the edge effects (insufficient or excessive edge treatment) of traditional designs, improving processing uniformity. It can also activate modules of corresponding widths based on the material width, enhancing energy efficiency.
