Accessoriess

The accessories of a multi-functional scraper mainly include the scraping assembly, pressure device, sample clamping and fixing device, and drive mechanism. The following are detailed descriptions:

Scraping Assembly: This includes the scraping bracket, scraping fingers, and scraping finger positioning sleeve. Scraping fingers are made of various materials, such as tungsten carbide (used for metal scraping heads to increase instrument lifespan) and polymethyl methacrylate (PMMA, used for plastic scraping fingers, 16mm diameter, 1mm thickness, 0.5mm edge radius, Shore D85 hardness). Metal scraping heads are available in various diameters such as 0.5mm, 0.75mm, 1mm (Erichsen 318), 3mm, 5mm, and 7mm to meet different testing needs.

Pressure Device: This typically consists of weights and a weight support rod. The total weight of the pressure weights and scraping assembly can be selected arbitrarily, such as 2N, 3N, 5N, 7N, 8N, 10N, 12N, 15N, and 20N, with a mass error not exceeding 1%, ensuring uniform unidirectional linear scraping motion under different loads.

Sample clamping and fixing device: Used to fix the sample in place, ensuring its stable position during testing and preventing movement or deflection, thus guaranteeing the accuracy of the test results.

Drive mechanism: Driven by a motor, this mechanism propels the scraping component in a linear scraping motion across the sample surface. Some instruments employ precision servo motors and ball screw drives, which play a crucial role in the accuracy of scraping speed control under relevant standards.
