Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of grinding equipment, and specifically relates to a dust-removing belt surface grinding machine. Background Technology
[0002] Grinding is essential for the creation of any product. In modern industrial production, especially in the casting industry, parts require belt grinding to remove casting burrs and flash, improving surface finish and smoothness. When grinding flat surfaces, a flat-plate belt sander is used. The workpiece is pressed into contact with the surface of the rotating belt, utilizing the cutting properties of the belt and the flat support of the plate to achieve grinding.
[0003] Traditional processing methods typically involve manually holding the workpiece and pressing it against the surface of a flat-plate belt sander for grinding. Because grinding requires significant pressure, this leads to prolonged periods of intense labor for operators during mass production, and the pressure can be uneven. Furthermore, traditional flat-plate belt sanders generally lack dust collection components, resulting in dust and sparks flying during grinding, which can harm the physical and mental health of employees and poses significant safety hazards.
[0004] Furthermore, the inherent structure of a flat-plate belt sander dictates that the sanding belt rotates at high speed against a metal plate. The friction between the belt and the plate, as well as the contact and grinding of the workpiece, generate heat. During mass production, continuous and prolonged friction can cause the metal plate to overheat, leading to a decrease in the joint strength of the sanding belt and ultimately, belt breakage. This increases the cost of consumables, and the flying sanding belt fragments can also cause personal injury to operators. Utility Model Content
