Description

Sand paper fixed establishment for sand paper equipment of polishing Technical Field The utility model relates to the technical field of sand paper fixing, in particular to a sand paper fixing mechanism for sand paper polishing equipment. Background The electric grinding and air grinding are the most commonly used two grinding modes in the current industrial production, and the electric grinding is usually a main force grinding tool which can rotate at a high speed through an electric driving grinding head so as to achieve the effect of quick grinding, the sand paper used by the sand paper grinding equipment is fixed by a fixing mechanism, and the fixing mode of the sand paper has a critical influence on the grinding effect, the working efficiency and the production cost; The traditional fixed establishment is many only through edge compaction (like single bolt briquetting or sticky), centrifugal force and frictional force when can not effectively resist polishing, when polishing equipment high-speed rotatory, the abrasive paper edge easily because of stress concentration perk, tear, initiate abrasive paper whole and drop even, lead to polishing precision decline or equipment trouble, and lead to abrasive paper polishing area unable tightening easily, can accelerate abrasive paper local abrasion, lead to abrasive paper whole life-span to shorten, consequently, propose an abrasive paper is abrasive paper fixed establishment for equipment.
