[0002] Edge bricks for rolled glass forming are mainly used in the production of glass by rolling method. They are placed on both sides of the lip bricks to facilitate edge shrinkage and expansion, timely adjustment of the board surface, and reduction of edge loss, that is, reduction of edge loss.

[0003] Chinese patent CN221460198U discloses a follow-up lifting rib mechanism for rolled glass forming, comprising a rib assembly and a lifting mechanism. The rib assembly is respectively arranged at the two ends of the lip brick and is synchronously driven by the lifting mechanism to move up and down to follow the lifting and lowering adjustment of the calendering machine, so that the upper and lower arc surfaces of the rib assembly correspond to the upper and lower calendering rollers of the calendering machine. By changing the installation method of the rib assembly and the lip brick, the rib assembly is arranged at the end of the lip brick, and the lifting function of the rib assembly is realized by a separately arranged lifting mechanism, thereby solving the problem that the lifting space of the calendering machine is limited by the rib brick, resulting in uneven heating and cooling of the upper and lower rollers, which leads to limited drawing speed and quality defects on the glass plate surface. In addition, by setting steel ribs with steel sharp corners, the rib assembly can better fit the contours of the upper and lower calendering rollers, preventing edge devitrification.

[0004] However, the retaining bricks in the existing technical solutions generally have the problem of heat dissipation at the edges, which affects the forming quality of the glass. Currently, the existing technology still lacks an effective solution for fully and evenly insulating the edges of the retaining bricks and facilitating quick installation and replacement of the insulation structure. Summary of the Invention

For the sake of simplicity, only the differences from the above embodiment are described below. The differences between this embodiment and the above embodiment are: As one of the implementation methods, Figure 1 、 Figure 7 As shown, the portion of the brick body 2 that matches the calendering roller has a sharp corner C210, and the size of the sharp corner C210 is smaller than the size of the sharp corner A110, so that a step suitable for installing the calendering roller sleeve is formed between the two.

[0077] In this embodiment, the sharp corner portion A110 and the sharp corner portion C210 are highly offset from the side surfaces that directly cooperate with the calendering roller. The structure of this embodiment is suitable for a calendering roller structure with a sleeve.

[0078] Example 7 The same or corresponding components in this embodiment are marked with the same reference numerals as those in the above embodiment. For the sake of simplicity, only the differences from the above embodiment are described below. The differences between this embodiment and the above embodiment are: As another embodiment, Figure 8 As shown, the portion of the brick body 2 that matches the calendering roller has a sharp corner portion C210, and the size of the sharp corner portion C210 is consistent with that of the sharp corner portion A110.

[0079] In this embodiment, the pointed corner portion A110 and the pointed corner portion C210 are directly matched with the side surface of the calendering roller at the same height. The structure of this embodiment is suitable for a calendering roller structure that does not require a sleeve.

[0080] Example 8 This embodiment provides a method for quickly replacing part of the structure of an electric heating temperature-controlled retaining brick for glass rolling forming: When replacing the first heating element 31, first open the top plate 101 of the alloy body 1, then lift the quick-install part B22 vertically to remove it, leaving space on one side of the quick-install part A21. This space allows the quick-install part A21 to be moved laterally and then the first heating element 31 thereon to be completely withdrawn from the sharp corner A110. The quick-install part A21 is removed by first moving it laterally and then lifting it vertically, so that the first heating element 31 installed thereon can be replaced separately. When replacing the second heating element 32 , first open the top plate 101 of the alloy body 1 , then directly lift out the quick-install part B22 vertically to replace the second heating element 32 installed thereon separately.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
