Preferably, the plate is movably arranged on the side wall of annealing furnace
Preferably, it is connected between plate and annealing furnace by movable component.
Preferably, when the width of plate is greater than the width of glass plate, the mistake for the traction roller being arranged on plate and annealing furnace
Position arrangement.
Preferably, when the width of plate is less than the width of glass plate, the traction roller that is arranged on plate and annealing furnace is set
In same mounting surface.
Preferably, further include seal assembly, the seal assembly is arranged on the side wall of annealing furnace, to sealing plug-in board and
Neutral gear between annealing furnace.
Preferably, the control device is at least provided with one group.
Compared with prior art, the utility model has the beneficial effects that
It is provided by the utility model it is a kind of for glass production when anneal in-furnace temperature and stress control device, including insert
Plate, there are two plate settings, is separately positioned on the two sides of glass plate, and the installation direction of plate and the forming direction of glass plate are mutual
It is perpendicular；The plate that the present apparatus uses both can will be divided into different temperature regions inside annealing furnace, can also play barrier and move back
The effect that stove lower outer air-flow rises；And then effectively improve the quality of production of glass plate.
Further, by adjusting the size in gap between plate forward position and glass plate, it can reduce annealing furnace lower part gas
The disturbance of annealing furnace internal gas flow is flowed, the airflow circulating path in different temperatures region can be relatively stable, and then controls temperature
The variation of degree and stress.

Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
As shown in Figure 1, the traction roller 3 that array length is greater than glass tape transverse width is provided on existing annealing furnace 1, benefit
Inhibiting effect is played to flow perturbation with traction roller 3, traction roller 3 is small in size, and cover-up surface is small, although part gas can also be obstructed
Stream, but inhibiting effect to flow perturbation or smaller.
As shown in Fig. 2, temperature and Stress Control device provided by the utility model, the control are arranged on annealing furnace 1
Device includes the plate 4 of several groups placement parallel to each other, and there are two every group of settings of plate 4, is separately positioned on the two of glass plate 2
Side, and the installation direction of plate 4 and the forming direction of glass plate 2 are orthogonal.
Plate 4 is flexibly connected with the side wall of annealing furnace 1, enables plate 4 along perpendicular with 2 forming direction of glass plate
Direction moves back and forth；To change the gap between plate 4 and glass plate 2, and then control the temperature field of 4 upper area of plate
Variation.
As shown in figure 3, the upper end of annealing furnace 1 is provided with two groups of traction rollers, respectively first group of traction roller and second group are led
Pick-up roll；Two groups of plates 4 are provided with below second group of traction roller.
As shown in figure 4, be provided with four groups of traction rollers on annealing furnace 1, respectively first group of traction roller, second group of traction roller,
