System and method for automatic adjustment of substrate glass pulling roller

Abstract

The invention discloses an automatic adjustment system and method for substrate glass traction rollers, comprising the following steps: 1. Evenly and continuously collect the distance between the traction rollers within the integral rotation time of the traction rollers to form a data set, and measure the substrate glass plate after the pull-down cutting 2. Calculate the centering correction value of the traction roller; calculate the actual diameter of the traction roller; 3. Adjust the centering of the traction roller, the adjusted value is the centering correction value of the traction roller control system The set diameter value of the traction roller is replaced by the actual diameter value of the traction roller, and the traction roller control system adjusts the linear speed of the traction roller to the required value according to the actual diameter value of the traction roller to complete the automatic adjustment. Automatically adjust the spacing and line speed of the traction rollers to ensure the quality and length of substrate glass forming. The invention improves the automation degree of the glass substrate traction system, reduces parameter adjustment errors caused by human subjective judgment and measurement errors in the production process, and improves the quality of the substrate glass in the production process.

Description

technical field [0001] The invention belongs to the field of substrate glass manufacturing, and relates to an automatic adjustment system and method for a substrate glass traction roller. Background technique [0002] In the manufacturing process of substrate glass, the traction roller clamping technology is the key technology for overflow down-draw method to produce large-size substrate glass. During the overflow down-drawing process, the molten glass enters the muffle furnace through the platinum pipe, flows down from the overflow tank, and is shaped into a glass with a certain width through the forming area. At this time, the thickness of the glass still does not meet the specified requirements. The substrate glass is drawn to the desired thickness by setting the speed ratio of the pulling roller. However, in the manufacturing process of the substrate glass, the traction roller is in direct contact with the substrate glass and has a pulling effect on the substrate. While...
