Traction mechanism for glass substrate production

Abstract

The invention discloses a traction mechanism for glass substrate production. The traction mechanism comprises a mounting base, a floating traction structure and a fixed traction structure are respectively mounted at the front side and the rear side of the upper end of the mounting base, and an adjusting driving mechanism for moving the floating traction structure is further mounted at the front side of the upper end of the mounting base; and the floating traction structure is connected with the fixed traction structure through a transmission mechanism, a heat insulation assembly is installed at the right side of the upper end of the fixed traction structure, and a clamping force display structure is installed at the right side of the heat insulation assembly. According to the traction mechanism, the floating traction structure, the fixed traction structure and the transmission mechanism are jointly matched to perform traction forming on a glass tape, and the clamping force of the floating traction structure and the fixed traction structure on a glass plate can be accurately adjusted through the adjusting driving mechanism and the clamping force display structure, so that the clamping force of the floating traction structure is effectively prevented from being too large or too small, the stability of the production state and the warping grade of a glass substrate can be ensured, and the forming quality of the glass substrate is ensured.

Description

technical field [0001] The invention belongs to the field of glass substrate production equipment, in particular to a traction mechanism for glass substrate production. Background technique [0002] The overflow pull-down is to send the molten glass into the overflow brick made of zircon refractory material with an inclined groove inside. The wall surface finally converges at the tip of the overflow brick to form a glass ribbon. Under the action of the gravity of the glass itself and the edge pulling machine and traction mechanism, it overcomes the influence of surface tension. According to the temperature system of the molding process, after shaping, annealing and cutting Form the substrate vitreous plate. During the forming process by this method, the glass surface does not contact any material, and has the characteristics of a free surface with flame polishing effect and extremely high flatness of the plate surface. However, in the existing traction mechanism, the clamp...

Problems solved by technology

However, in the existing traction mechanism, the clamping force of the traction roller on the glass plate cannot be accurately evaluated or adjusted, and the clamping force is prone to be too large or too small

If the clamping force of the traction roller is too large, it is easy to cause the hardened glass plate to be stressed to form dark cracks. When the glass plate is pulled down by multiple sets of traction rollers or the glass plate is shaken by cross-cutting, the cracks will be further extended and expanded to cause the plate to break. It may even lead to the risk of material blocking in the furnace, causing irreparable losses to key molding equipment and production quality; if the clamping force of the traction roller is too small, the static friction force between the boss of the short roller and the contact surface of the glass plate will be insufficient, which will affect the pulling effect of the short roller And glass substrate warping grade is stable, the improvement of glass substrate molding quality and grade consistency cannot be guaranteed
