A split drive short roller device for pulling glass

Abstract

The invention provides a split driving short roller device for pulling glass, which includes a horizontal sliding table mechanism; the horizontal sliding table mechanism includes a bottom plate, a guide rail is arranged on the bottom plate, and two sliding plates are slidably arranged on the guide rail, corresponding to each sliding plate. There is a clamping mechanism, a driving mechanism and an adjusting mechanism; the clamping mechanism includes a short roller mandrel fixed on the sliding plate; one end of the short roller mandrel is the glass clamping end, the other end is the driving end, the short roller mandrel The asbestos roller is set on the glass clamping end of the glass; the axial direction of the short roller mandrel is perpendicular to the direction of the guide rail; the driving mechanism is fixed on the sliding plate, and its driving shaft is coaxially connected with the driving end of the short roller mandrel; The mechanism includes a pull rod for controlling the sliding of the sliding plate and a counterweight for adjusting the clamping force of the asbestos roller. The driving short roller device of the present invention is independently set, and a group of rollers extend into the hot-end annealing furnace from both sides of the annealing furnace oppositely, respectively clamp and pull the substrate glass on both sides, the manufacturing cost is low, and it is convenient and flexible to adjust.

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...
