Description

Technical Field

[0001] This utility model relates to the field of scraper roller equipment technology, and in particular to a top plate structure for scraper roller equipment. Background Technology

[0002] In many industrial sectors that rely on coating processes, competition for product quality is becoming increasingly fierce, and the requirements for coating precision have reached unprecedented levels. In the electronic display industry, such as the manufacturing process of liquid crystal displays and organic light-emitting diode displays, it is necessary to uniformly coat an extremely thin layer of functional materials on the substrate. The thickness is usually between nanometer and micrometer. Even the smallest coating error can lead to bright spots, dark spots, or uneven color in the display effect, seriously affecting the product yield and performance. Traditional top plate structures for scraper rollers cannot achieve such high-precision positioning and stable support, resulting in inconsistent coating quality that cannot meet the stringent standards of high-end electronic product manufacturing. Therefore, there is an urgent need to develop more advanced top plate structures to ensure coating precision.

[0003] Currently, the top plate structure of squeegee roller equipment on the market mainly consists of a supporting main component and an adjustment and control component. Traditional top plates often adopt a simple bracket design, which is not mechanically sound. In the packaging and printing industry, the squeegee rollers in flexographic and gravure printing generate significant centrifugal force and vibration when rotating at high speeds. Traditional top plates are unable to effectively resist these external forces, easily causing wobbling and displacement. This results in unstable contact pressure between the squeegee roller and the printing plate, leading to inconsistent ink transfer and uneven line thickness and color variations in the printed pattern, seriously affecting the quality and aesthetics of the printed product. Furthermore, adjusting the height and angle of the squeegee roller using traditional top plates relies on manual operation, which is complex. In the textile printing and dyeing industry, different fabrics and printing patterns have specific requirements for the angle and pressure of the squeegee roller, necessitating frequent adjustments to the roller parameters. Each adjustment of a traditional top plate requires operators to use wrenches, screwdrivers, and other tools to repeatedly tighten screws and nuts to change the position and angle of the top plate. This is not only time-consuming and labor-intensive but also makes it difficult to guarantee accuracy. When frequently changing printing jobs, this cumbersome adjustment process severely slows down the production schedule and reduces production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a top plate structure for a doctor roller device, which aims to improve the problem that traditional top plates in the prior art are unable to effectively resist these external forces and are prone to shaking and displacement, which makes the contact pressure between the doctor roller and the printing plate unstable.
