Split type drive short roller device for drawing glass

Abstract

The invention provides a split type drive short roller device for drawing glass. The split type drive short roller device comprises a horizontal sliding table mechanism, wherein the horizontal slidingtable mechanism comprises a bottom plate, wherein guide rails are arranged on the bottom plate, two sliding plates are arranged on the guide rails in a sliding manner, and a clamping mechanism, a drive mechanism and an adjusting mechanism are arranged corresponding to each sliding plate; each clamping mechanism comprises a short roller mandrel fixed on the corresponding sliding plate, one end ofthe short roller mandrel is a glass clamping end, the other end is a drive end, the glass clamping end of the short roller mandrel is sleeved with an asbestos roll wheel, and the axial direction of the short roller mandrel is vertical to the trend of the guide rails; each drive mechanism is fixed on the corresponding sliding plate, and a drive shaft of the drive mechanism is coaxially connected with the drive end of the corresponding short roller mandrel; each adjusting mechanism comprises a pull rod for controlling sliding of the corresponding sliding plate and counter weight for adjusting clamping force of the corresponding asbestos roll wheel. The drive short roller device is independently arranged, a group of rollers extend into a hot-end annealing furnace from the two sides of the annealing furnace oppositely and clamp and draw substrate glass on the two sides respectively, the manufacturing cost is low, and the flexible adjustment is convenient.

Description

technical field [0001] The invention belongs to the field of forming equipment for TFT substrate glass, and relates to a split driving short roller device for pulling glass. Background technique [0002] For high-generation substrate glass production lines, multi-roller pulling technology is one of the key technologies for forming. With the continuous upgrading of the substrate glass production line, it will become more and more difficult to rely on the current long roller technology to draw the glass in the hot end forming equipment. , if the long roller technology is adopted, the length of the roller will reach more than 3 meters, which is difficult to manufacture and high in cost. Moreover, the existing long roll technology is that the rolls are fixedly installed in the forming furnace, which cannot realize the requirement of flexible adjustment in the process. Therefore, the design and development of a new type of driving short roller device for pulling glass has becom...
