Description

Technical Field

[0001] The present invention relates to the technical field of polishing of glazed floor tile blanks, and specifically relates to a polishing device and a polishing method for glazed floor tile blanks. Background Art

[0002] Glazed floor tiles are a type of ceramic tile with a polished glaze surface, commonly used for floor decoration. They are widely used in homes, commercial and public places due to their excellent visual effects and high wear resistance. The production process of glazed floor tiles is unique, combining the advantages of ceramic tiles and the aesthetic effects of glazed tiles, capable of providing a smooth, flat and shiny surface.

[0003] When producing glazed floor tiles, a polishing operation is required. When polishing the glazed floor tile blanks, two polishing steps of rough polishing and fine polishing are needed. Coarse polishing uses coarser abrasives, mainly for removing large defects and unevenness on the surface; while fine polishing uses finer abrasives, focusing on removing small flaws and enhancing gloss. During the process of coarse polishing, dust, waste or residues will be generated, and the dust generated by coarse polishing is finer and will be suspended in the production area due to air circulation, polluting the production area and thus affecting the physical health of production personnel.

[0059] With the above structure, three conveyor belts 2 with equal intervals are installed between the two drums 10 and are driven by the feeding motor 12. This feeding method is the same as the principle in the prior art. The anti-slip blocks 11 installed on the surface of the conveyor belt 2 can increase the friction force of the glazed floor tile blank on the surface of the conveyor belt, and cooperate with the two limit strips 55 to prevent the blank from shifting during the polishing process. The maintenance door 6 is convenient for maintaining the relevant equipment in the polishing box 5.

[0060] Working principle: When the device is in use, first place the brick blank to be polished at the input end of the conveyor belt 2, connect the two liquid inlet pipes 4 to external cooling water, and then start the device to polish the glazed floor tile blank. The feeding motor 12 drives the roller 10 to rotate, and the roller 10 drives the conveyor belt 2 to move to convey the brick blank. During the conveying process, start the rough polishing electric push rod 16. The movable end of the rough polishing electric push rod 16 drives the connecting rod 18 to move downward, and the connecting rod 18 drives the two cross bars 14 to move downward. The two cross bars 14 respectively drive the two rough polishing rollers 17 to move downward, so that the rough polishing areas of the two rough polishing rollers 17 are located in the conveying area of the brick blank. At this time, start the rough polishing motor 13. The output end of the rough polishing motor 13 drives one of the rough polishing rollers 17 to rotate. The rough polishing roller 17 drives the primary drive wheel 27 to rotate, and the primary drive wheel 27 drives the primary driven wheel 26 to rotate through the primary transmission belt 25. The primary driven wheel 26 drives the other rough polishing roller 17 to rotate to perform secondary rough polishing on the surface of the material.

[0061] During the rough polishing process, the rough polishing roller 17 away from the rough polishing motor 13 drives the secondary gear 22 to rotate. The secondary gear 22 drives the primary gear 21 to rotate, and the primary gear 21 drives the impeller 29 to rotate. The impeller 29 stirs the water in the water storage pipe 23 to make it have kinetic energy and spray it out through the nozzle 28 to spray cooling water on the rough polishing area to achieve the effect of cooling and dust reduction in the rough polishing area. The number of teeth of the secondary gear 22 is less than that of the primary gear 21 to ensure the rotation speed of the impeller 29.

[0062] Start the fine polishing electric push rod 3 and the drive motor 40. The movable end of the fine polishing electric push rod 3 drives the installation box 15 to move downward. The installation box 15 drives the two racks 39 to move downward. The two racks 39 drive the two connecting blocks 35 to move downward. The connecting blocks 35 drive the installation plate 56 to move downward. The installation plate 56 drives the multiple fine polishing motors 57 to move downward. The multiple fine polishing motors 57 drive the corresponding fine polishing discs 46 to move downward, so that the fine polishing discs are located in the conveying area of the brick blank. At the same time, the fixed rod 34 makes the cleaning scraper 42 fit with the brick blank. The surface of the brick blank is cleaned by the cleaning scraper 42 to scrape off the residual dust mixture, impurities, etc. on the surface. After the cleaning is completed, the surface of the polishing material is finely polished by the two groups of fine polishing discs 46 to complete the polishing of the glazed floor tile blank.
