Technical Field

[0001] The utility model relates to the technical field of polishing equipment, in particular to a ceramic tile surface polishing machine. Background Art

[0002] Ceramic tiles, rock slabs, stone, and artificial stone are common building materials, collectively referred to as ceramic tiles. Tile polishing is a common surface treatment technique that creates a smoother, brighter surface, enhancing both the aesthetics and texture of the tile. Polished tiles are a type of tile that has been ground and polished. With their glossy appearance and excellent transparency, polished tiles can brighten a room's appearance when used as floor tiles.

[0003] However, the tile polishing equipment in the prior art has a long production line, many components, and high cost. In addition, the tile surface is ground and polished unevenly, which easily forms water ripples, has high surface roughness, and is not smooth and flat. Utility Model Content

The active and passive rollers are located parallel to the left and right ends of the frame. The left and right ends of the conveyor belt are respectively sleeved over the active and passive rollers. The active rollers are connected to the output shaft of the conveyor motor and are driven by the motor for rotation. The front and rear ends of the active and passive rollers are connected to the frame via bearings. A horizontal platform is located below the conveyor belt to support the conveyor belt and tiles, maintaining a level surface.

[0011] Preferably, the conveying assembly further comprises a tensioning mechanism for adjusting and tightening the conveyor belt. The tensioning mechanism causes the driven roller to slide left and right in the chute by adjusting the screw to tighten the conveyor belt.

[0012] The polishing assembly includes a lifting frame, a lifting power assembly, a polishing unit, and a swing arm assembly;

[0013] The bottom of the lifting power assembly is connected to the slide rail; the lifting frame is arranged below the lifting power assembly and is movably connected to the lifting power assembly;

[0014] The polishing units are arranged vertically on a lifting frame, preferably nine in number, divided into two rows with five on the left and four on the right; the axes of the polishing units in the right row are aligned with the midlines of the two adjacent polishing units in the left row.

[0015] The lifting power assembly includes a mounting plate, a reduction motor, a driving sprocket, a transmission chain, and a driven sprocket; the mounting plate is horizontally arranged; the reduction motor is vertically arranged on the mounting plate, and the outer wall of its output shaft is sleeved with a horizontally arranged driving sprocket, which drives the driving sprocket to rotate. Bearing seats are provided at the four corners of the mounting plate; the lead screw is vertically arranged, and its upper end is sleeved with a bearing and then passes through the bearing seat, and its top end is sleeved with a driven sprocket. The transmission chain is sleeved on the driving sprocket and the driven sprocket, meshing the transmission, driving the driven sprocket to rotate, and then driving the lead screw to rotate.

The buffer spring is sleeved on the outer wall of the push rod, with its ends respectively contacting the limit step and the connector. The buffer spring ensures smooth and cushioned force when the push rod pushes and pulls the lifting frame, preventing sudden stops and starts that would cause noise and vibration, and affect the life of moving parts.

[0020] Preferably, the lifting power assembly also includes a tensioning assembly; the tensioning assembly includes a mounting block, a slide rod, a tensioning gear, and a tensioning spring; the mounting block is fixed to the mounting plate and is provided with a mounting hole, in which a slide rod is horizontally installed; the outer end of the slide rod is connected to a nut, and the other end is provided with a limit step; the tensioning spring is sleeved on the outer wall of the slide rod, with its two ends respectively contacting the mounting block and the limit step; a tensioning gear is provided above the limit step, and the tensioning gear is meshed with the transmission chain. Because the compressed tensioning spring continuously applies elastic force to the tensioning gear to move forward, even if the components undergo slight deformation during long-term operation, the transmission chain will remain taut.

[0021] Briefly describe its working principle:

[0022] The tiles to be polished are conveyed to the bottom of the polishing assembly. The reduction motor of the lifting power assembly drives the screw to rotate via a sprocket, causing the sliding sleeve mounted on the screw to descend (descending when the blade is advanced and ascending when the blade is retracted), driving the lifting frame and polishing unit to descend. When the polishing unit's grinding disc contacts the top surface of the tile, it can be polished. As the conveying assembly conveys the tiles, they are transported to the right. Simultaneously, the polishing unit (lifting frame) is pushed and pulled by the swing arm assembly, causing its grinding disc to rotate and move back and forth. This method of tile conveying and polishing ensures that the entire top surface of the tile is evenly polished by the polishing unit.

[0023] Beneficial effects of the utility model:

[0024] Its structure is simple and beautiful, and its operation is stable and reliable. It can quickly and efficiently polish and grind the surface of ceramic tiles and rock slabs with excellent polishing effect. The surface roughness of the ceramic tiles is low, without water ripples, and smooth and flat. BRIEF DESCRIPTION OF THE DRAWINGS
