[0003] Chinese patent CN221460198U discloses a follow-up lifting type edge blocking mechanism for calender glass forming, which comprises an edge blocking assembly and a lifting mechanism. The edge blocking assembly is arranged at the ends of the lip brick and is synchronously driven by the lifting mechanism to move up and down, so as to adapt to the lifting adjustment of the calender and make the upper and lower arc surfaces of the edge blocking assembly correspondingly abut against the upper and lower calender rollers. By changing the installation mode of the edge blocking assembly and the lip brick, the edge blocking assembly is arranged at the ends of the lip brick, and the lifting function of the edge blocking assembly is realized by the separately arranged lifting mechanism, solving the problem of uneven heating and cooling of the upper and lower rollers due to the limitation of the edge blocking brick on the lifting space of the calender, which limits the drawing speed and causes quality defects on the glass plate surface.

[0104] This embodiment provides a method for quickly replacing the part structure of an electric heating temperature control blocking edge brick for glass calender forming:

[0105] When the first heating element 31 is replaced, the top plate 101 of the alloy body 1 is first opened, and then the quick-mounting part B22 is directly taken out vertically, so as to leave a space for the quick-mounting part A21 on one side and the space satisfies that the first heating element 31 on the quick-mounting part A21 can be completely withdrawn from the sharp corner part A110 after lateral side displacement. The quick-mounting part A21 is taken out by the way of first lateral side displacement and then vertical lifting, so as to individually replace the first heating element 31 mounted thereon.

[0106] When the second heating element 32 is replaced, the top plate 101 of the alloy body 1 is first opened, and then the quick-mounting part B22 is directly taken out vertically to individually replace the second heating element 32 mounted thereon.

[0107] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
