Scraper system is a device widely used in many fields, mainly used to scrape, level or apply substances.
Scraper blade
Material selection: The material of the scraper blade varies according to the specific application scenario. Common materials include metal (such as stainless steel, carbon steel), rubber and plastic. Stainless steel blades have high hardness, good wear resistance and corrosion resistance, and are suitable for scraping harder substances, such as in the printing industry for scraping excess ink on printing plates. Squeegees are flexible and can fit tightly to irregular surfaces. They are often used to apply glue or clean soft surfaces, such as in car windshield cleaning devices to remove water stains.
Shape and size: Squeegee blades come in a variety of shapes, including straight, curved, triangular, etc. Straight scrapers are suitable for scraping and leveling large areas, such as for leveling asphalt in road construction; curved scrapers can better fit round or curved surfaces, such as in the cleaning of industrial pipe walls; triangular scrapers can accurately handle corners and narrow areas, such as cleaning impurities around solder joints in circuit board repair. Blades also vary in size, with their length, width and thickness depending on the scope of work and the required strength. For example, large industrial scraper blades may be several meters long and are used to scrape large areas of material, while small manual scraper blades may be only a few centimeters long.
Scraper holder
Structural design: The scraper holder is the component that supports the scraper blade and fixes it in place. It is designed with stability and adjustability in mind. In some high-precision applications, such as precision printing or electronic equipment manufacturing, the scraper holder may be equipped with a fine-tuning device for precisely adjusting the distance and angle between the scraper blade and the treated surface. The structure of the holder can be a simple handheld type for manual operation, or a complex mechanically mounted type for automated production lines.
Material and strength: The scraper holder is usually made of metal (such as aluminum alloy, steel) or high-strength plastic. Aluminum alloy holders have light weight and good corrosion resistance, suitable for occasions that require frequent movement or hand-held operation; steel holders have higher strength and can withstand greater pressure and impact, and are often used in industrial heavy-duty scraper systems.
Drive device (if applicable)
Manual drive: In some simple scraper systems, such as manual putty scraping tools, the scraper is driven by manual force. This method is flexible to operate and can adjust the scraping force and speed at any time according to actual conditions, but the efficiency is relatively low and it requires certain physical strength and skills of the operator.
Mechanical drive: For large-scale industrial applications, such as paper surface treatment in paper mills or coating processes in automobile manufacturing, scraper systems are usually mechanically driven. Mechanical drive can be electric, pneumatic or hydraulic. Electric drive scraper system can accurately control the movement speed and stroke of the scraper, and realize the reciprocating or rotating motion of the scraper through the motor and transmission mechanism. Pneumatic drive has the characteristics of fast response speed and no pollution, using compressed air to push the piston or cylinder to drive the scraper. Hydraulic drive scraper system can generate greater power and is suitable for occasions requiring high-pressure scraping, such as metal surface pretreatment in heavy machinery manufacturing.
