Lift-up roller arrangement for electronic float glass

A lift-up roller arrangement for electronic float glass, including a plurality of lift-up rollers (2) rotatablely arranged on an inner wall of an annealing kiln (1), wherein a plurality of boron nitride rings (3) are fixedly sleeved on an outer side wall of each of the lift-up rollers (2);

• a heat-resisting steel tube (4) is arranged on each of both sides of each of the lift-up rollers (2);
• a plurality of exhaust holes are arranged on an outer side wall of the heat-resisting steel tube (4);
• the heat-resisting steel tube (4) is in communication with an external hot gas supply case;
• and a plurality of cleaning assemblies used in cooperation with the lift-up rollers (2) are arranged at an inner bottom of the annealing kiln (1), wherein, multiple pairs of first support frames (5) are symmetrically fixed at the inner bottom of the annealing kiln (1);
• a lifting rod (6) is arranged on an upper end surface of each of the first support frames (5);
• two bearing rings (7) are fixedly sleeved on the outer side wall of each of the heat-resisting steel tubes (4) in a symmetrical manner;
• and an upper end of the lifting rod (6) is fixedly connected to an outer side wall of the bearing ring (7).
