Polishing device for surfaces of building boards

Abstract

The invention discloses a polishing device for surfaces of building boards. The polishing device comprises a support, a polishing device body, a wire, sliding rods, a fulcrum bar, a control cabinet, a collection box, a fixing groove, a base, suction holes, clamping plates, a bearing frame, extending and retracting rods, a limiting clamping plate, a polishing disk, lantern rings, a rotating rod, an inner rod and a spring. The polishing device has the beneficial effects that the two sliding rods are arranged in the support, the polishing device body is arranged on the sliding rods through the lantern rings, the polishing device body can slide on the sliding rods to adjust the polishing position in the polishing process, and therefore uniform polishing is achieved. The suction holes are formed in the inner wall of one side of the fixing groove and communicate with a draught fan in the collection box, chippings produced in the polishing process can be absorbed into the collection box through the suction holes, and the situation that the chippings produced in the polishing process affect the polishing effect is avoided. By arranging the clamping plates which can extend and retract are arranged on the inner walls of the two sides of the fixing groove, the building boards are fixed through the extending and retracting clamping plates, and therefore it is ensured that the boards cannot shake in polishing.

Description

technical field [0001] The invention relates to a polishing device, in particular to a polishing device for the surface of building boards, and belongs to the field of building material processing. Background technique [0002] There are many kinds of building materials, the most representative of which are building panels, building panels and panels used in building decoration. Building panels are usually made into flat rectangular shapes of standard sizes as components of walls, ceilings or floors. It also mostly refers to metal plates formed by forging, rolling or casting. Building plates are divided into thin plates, medium plates, thick plates, and extra-thick plates according to their own thickness. Building panels need to go through a series of processing procedures before they are put into use, including surface polishing of the panels, and polishing requires the use of polishing devices. [0003] However, the existing polishing devices for the surface of building p...
