Description
Technical Field
[0001] The utility model relates to the technical field of static elimination of printing machines, in particular to an automatic static elimination device for printing machines. Background Art
[0002] A printing press is a device that transfers ink onto printing materials such as paper, plastic, and cloth through mechanical pressure or other means to reproduce images or text in large quantities. Common types of printing presses include offset, gravure, and flexographic presses. During the high-speed printing process, materials like paper and plastic film constantly rub against machine components, generating significant amounts of static electricity. This static electricity can cause problems such as paper sticking, uneven ink distribution, and dust absorption, compromising print quality. To address these issues, printing presses must use automatic static eliminators that release positive and negative ions to neutralize static electricity, ensuring smooth material transfer and consistent printing results while reducing scrap and improving production efficiency.
[0003] Traditional automatic static elimination systems for printing presses typically eliminate static electricity using ion rods or discharge rods installed at strategic locations. These devices, powered by a high-voltage power supply, generate positive and negative ions that directly neutralize static electricity accumulated on the surface of printed materials. During operation, the high-voltage power supply and grounding system ensure safety, and regular maintenance and cleaning of the discharge needles maintain stability and effectiveness. In this way, static elimination systems prevent problems such as material sticking and uneven ink distribution, improving print quality.
[0004] When using traditional automatic static elimination devices for printing machines, the ion rod is usually fixed on a fixed bracket and lacks a flexible adjustment mechanism. When the ion rod is too far away, the ions diffuse insufficiently and cannot effectively neutralize static electricity; if the distance is too close, sparks may be generated or the material may be damaged. As a result, the distance between the ion rod and the printed material is difficult to dynamically adjust according to different materials, static electricity intensity or printing conditions.

[0027] Working principle: When the automatic static elimination device of the printing press is needed, first, the paper is printed by the printing press and then transported to the bottom of the gantry bracket 3 through the conveyor belt 1. At this time, the motor 9 is started to drive the bidirectional screw 10 to rotate, thereby driving the threaded sleeves 11 on both sides to move relative to each other, and then driving one end of the linkage plate 12 to move, and then the insulating protective cover 13 is pushed to move by the other end of the linkage plate 12, thereby driving the static elimination ion rod 7 inside the insulating protective cover 13 to move up and down and adjust, and then the high-voltage power supply 4 applies voltage to the electrodes inside the static elimination ion rod 7. When the electrode voltage is high enough, the gas molecules in the surrounding air are ionized to form positive ions and negative ions. At this time, the positively charged area will attract negative ions, and the negatively charged area will attract positive ions. The opposite polarity ions neutralize, so that the static charge on the surface of the paper gradually decreases until it is eliminated. The eliminated static electricity is transported to the ground through the grounding wire 8 to prevent the charge from re-accumulating. The paper continues to be transported, and then the static electricity removal status is detected by the static electricity detector 5 at the rear;
