Polishing device and polishing method for improving flatness of float glass

Abstract

The invention belongs to the technical field of float glass polishing, and discloses a polishing device and a polishing method for improving the flatness of float glass. The polishing device comprises a feeding mechanism, a polishing mechanism and a flushing mechanism, wherein the feeding mechanism comprises a shell and a conveyor belt device; a cleaning chamber and an installation chamber are arranged in the shell; the conveyor belt device is fixed into the installation chamber; the top surface of the conveyor belt device is higher than the top surface of the shell; a conveyor belt in the conveyor belt device adopts a fine mesh-shaped structure; a U-shaped plate, a guiding roller group and a cleaning fluid guiding box are further arrange din the installation chamber; and a belt guiding roller group is further arranged in the cleaning chamber. According to the polishing device and the polishing method for improving the flatness of the float glass provided by the invention, the processes of automatic feeding, automatic positioning, automatic polishing, automatic cleaning and drying and the like are combined, so that the working efficiency of the whole polishing device can be greatly improved; and the guiding roller group is contained in an automatic feeding structure, so that the separation between a polishing area and a cleaning area is effectively realized, and the polishing quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of float glass polishing, and in particular relates to polishing equipment and a polishing method for improving the flatness of float glass. Background technique [0002] In the production process of float glass, polishing is an indispensable step. According to the principle of action in the existing technology, it can be divided into three categories: mechanical cutting, chemical treatment, and surface flow treatment. Finally, the float glass needs to be cleaned; [0003] In view of the above polishing process, most of the existing technologies use manual transfer or conveyor belt transfer to realize the connection between polishing operation and cleaning operation. Among them, manual transfer has the problems of inconvenient operation, easy damage of float glass, high cost and low efficiency. For conveyor belt transfer, the float glass needs to be placed on the conveyor belt. In order to ensure the stabil...

Problems solved by technology

[0003] In view of the above polishing process, most of the existing technologies use manual transfer or conveyor belt transfer to realize the connection between polishing operation and cleaning operation. Among them, manual transfer has the problems of inconvenient operation, easy damage of float glass, high cost and low efficiency. For conveyor belt transfer, the float glass needs to be placed on the conveyor belt. In order to ensure the stability of the float glass in this way, there is generally a large friction between the conveyor belt and the float glass. Once the float glass is polished or Relative displacement during the cleaning process will cause wear on the non-polished surface due to friction, resulting in a decrease in the flatness of the non-polished surface;

[0004] In addition, the use of conveyor belt transfer also has the problem that the cleaning liquid flows to the polishing position, affecting the polishing effect, and the polishing dust adheres to the conveyor belt to further increase the wear of the non-polishing surface, which is very likely to cause secondary damage to the float glass
