[0044] Figure 1 The overall structure of the glass annealing lehr transition roll table curtain device is shown according to some embodiments of the application. In some embodiments of the application, the glass annealing lehr transition roll table curtain device can include a curtain plate 100, a hanging strip 200 and a guide groove 300. Specifically, the hanging strip 200 is arranged to be detachably mounted on the upper edge of the curtain plate 100, and the guide groove 300 can have a groove structure extending along the width direction of the transition roll table, and the hanging strip 200 is inserted into the groove structure of the guide groove 300 to mount the curtain plate 100 to the guide groove 300. Wherein, the hanging strip 200 can be equally spaced in the length direction and a plurality of expansion joints (not shown) are arranged. Figure 1

[0045] ​Compared with the prior art, the plurality of expansion joints arranged on the hanging strip of the curtain device in the scheme of the present application can ensure that the curtain device can avoid deformation due to thermal expansion and cold contraction in an alternating cold and hot environment.

[0046] The curtain plate 100 of the present application is generally plate-shaped, and a plane flush with at least one half of the plate-shaped curtain plate 100 is referred to as a plane on which the curtain plate 100 is located. As shown in Figure 2 The curtain plate 100 can have a bending structure 110 to increase the rigidity of the curtain plate 100. Specifically, the bending structure 110 can be bent at an angle of 30°-90° with respect to the plane on which the curtain plate 100 is located; each bending structure 110 extends in a first direction on the plane on which the curtain plate 100, 100a, 100b is located; and a plurality of bending structures 110 are distributed equidistantly in a second direction perpendicular to the first direction on the plane on which the curtain plate 100 is located. In some embodiments of the present application, the first direction is the width direction of the transition roller table, and the second direction is the vertical direction. In Figure 3a In the embodiment shown in Figure 3b In the embodiment shown in Figure 3c In the embodiment shown in

[0047] To further resist deformation due to thermal expansion and cold contraction, in some embodiments of the present application, a plurality of curtain plates 100 can be arranged in the width direction of the transition roller table. As shown in Figure 4 As shown in

[0048] Returning to Figure 2 In an embodiment of the present application, the hanging strip 200 includes a pair of hanging strip portions 200a and 200b having an L-shaped cross section. To Figure 5The shown hanging strip part 200b includes a mounting part 210 and a supporting part 220 which are perpendicular to each other and both extend along the length direction of the hanging strip part 200b. The mounting part 210 includes expansion joints 211 which extend perpendicularly to the supporting part 220, and a plurality of mounting holes 212 which are arranged at equal intervals along the length direction of the mounting part 210.

Thus, even if the hanging strip parts 200a and 200b frequently undergo cold and hot alternation, the whole hanging strip parts 200a and 200b will not be bent and deformed due to thermal expansion and contraction.

[0049] Referring to Figures 2 to 3c In the installed state, the mounting parts 210 of the pair of hanging strip parts 200a and 200b abut against both sides of the upper edge of the curtain plate 100 back to back, and the fixing of the curtain plate 100 and the hanging strip 200 is achieved by screws passing through the mounting holes 212 corresponding to each other and the through holes provided on the upper edge of the curtain plate 100. The guide groove 300 is provided with a pair of cantilever structures 310 opposite to each other at the opening of the groove-shaped structure, to support the supporting part 220 of the hanging strip 200. The above mounting method not only has firm joint, but also is convenient for disassembly and assembly.

[0050] Further as Figure 1 shown, the curtain blocking device according to the present application can further include a cross beam 400 and a lifting rod 500. Specifically, the cross beam 400 is arranged to extend above the guide groove 300 along the width direction of the transition roller table, and a cross beam lug 410 is arranged thereon, so that a lifting mechanism, such as a steel wire rope connected with a driving motor, etc., is connected to the cross beam 400, to realize the lifting movement of the whole cross beam 400. The lifting rod 500 is arranged to connect the guide groove 300 and the cross beam 400. The lifting rod 500 is movable relative to the cross beam 400 along the extension direction of the lifting rod 500, to drive the guide groove 300 to move up and down relative to the cross beam 400. This design can assist in realizing the relative position adjustment of the curtain blocking device in the vertical direction. In the embodiment of the present application, the guide groove 300 is provided with a hook 320 on the side opposite to the opening of the groove-shaped structure, wherein the guide groove 300 is connected to one end of the lifting rod 500 through the hook 320, to assist in the convenient disassembly and assembly of the guide groove 300; the other end of the lifting rod 500 extends through the cross beam 400, and the relative position of the two is defined by a positioning mechanism. Preferably, an adjusting hand wheel 600 can be arranged at the connection between the lifting rod 500 and the cross beam 400, to adjust and define the position of the lifting rod 500 relative to the cross beam 400. In Figure 1In the shown embodiment, the adjusting handwheels 600 include an upper adjusting handwheel 610 arranged above the cross beams 400 and a lower adjusting handwheel 620 arranged below the cross beams 400, so as to respectively adjust and limit the rope movement of the hangers 500.
