Description

Supporting and adjusting structure of glass heating furnace forming block Technical Field The utility model relates to the field of glass tempering equipment, in particular to a supporting and adjusting structure of a glass heating furnace forming block. Background In a conventional glass tempering furnace, pre-perforated forming blocks are typically placed directly on vertically laid ceramic fiber insulation boards. The mounting mode has obvious technical defects that firstly, the concentricity of the pre-opening hole on the forming block and the ceramic roller way is difficult to accurately adjust because the forming block is supported by the ceramic fiber board. Once installed in place, even if a poor centering is found, effective correction cannot be performed, resulting in friction with the wall of the hole when the roller way is in operation. More seriously, ceramic fiber materials undergo thermal shrinkage and collapse deformation under long-term high-temperature operating environments. The deformation gradually inclines the originally horizontally placed forming blocks, and lateral pressure is generated on the penetrated ceramic roller way. On one hand, the continuous friction pressure can directly damage the surface of the roller way, and on the other hand, the inclined forming block can prevent the roller way from rotating normally, so that uneven transmission speed is caused, and finally scratches are formed on the surface of the toughened glass. The existing mounting structure cannot prevent the problem caused by thermal deformation, and a simple and effective adjustment means is also lacking. When the problem occurs each time, the machine is required to be stopped for complex disassembly and reinstallation, and the production efficiency and the product quality are seriously affected. Therefore, there is an urgent need to develop a novel supporting and adjusting structure for forming blocks, which can effectively overcome the defects of the conventional mode, and ensure stable supporting and accurate centering performance in a high-temperature environment for a long time. Disclosure of utility model The utility model aims to solve the technical problems of providing a supporting and adjusting structure of a forming block of a glass heating furnace, which can effectively avoid the phenomenon that the ceramic roller way is rubbed and pressed obliquely by the forming block caused by the collapse of a ceramic fiber heat-insulating material due to heating, thereby damaging the surface of the ceramic roller way and the toughened glass surface is scratched due to the fact that the ceramic roller way is rubbed and pressed obliquely by the forming block to stall. In order to achieve the purpose, the technical scheme includes that the supporting and adjusting structure of the glass heating furnace forming block comprises a roller way perforated plate and a positioning adjusting assembly, wherein the roller way perforated plate is used for supporting and adjusting the forming block, the roller way perforated plate is integrally L-shaped, one side of the forming block is supported on the roller way perforated plate, the bottom of the other side of the forming block is supported and fixed by a vertical supporting plate, a U-shaped guide fixing clamp is sleeved on the lower portion of the supporting plate, a positioning hole is formed in the bottom of the U-shaped guide fixing clamp, the positioning adjusting assembly comprises an adjusting bolt and an adjusting nut, the adjusting nut is vertically fixed on a heating furnace bottom plate, the adjusting bolt penetrates through the whole nut and is connected with the positioning hole, and the positioning adjusting assembly is used for adjusting the height of the supporting plate to enable the forming block to be concentric with a ceramic roller way. The forming block pulling piece is characterized by further comprising a forming block pulling piece, one end of the forming block pulling piece is fixed on the forming block, the other end of the forming block pulling piece is fixed on the supporting plate and used for fixing the adjusted forming block, and a supporting nail used for transverse reinforcement is arranged in the middle of the forming block pulling piece in a penetrating mode.
