[0038] The forming furnace of the prior art may cause the glass ribbon to swing due to equipment stability or other reasons when the glass ribbon formed by overflow of the glass liquid flows through the forming channel, which is extremely easy to cause the glass ribbon to stick to the heating wire on the inner wall of the forming furnace body. At present, manual processing is adopted for processing, the processing speed is slow, the blocking phenomenon may be caused, and the risk coefficient is high.
[0039] In order to solve the technical problem, the utility model provides a kind of anti-blocking forming furnace 1000 and overflow forming equipment using the anti-blocking forming furnace 1000 to solve the above problems.
[0040] Please refer to Figures 1 to 3 The anti-blocking forming furnace 1000 includes a furnace body 1, two heating assemblies 2, two adjusting assemblies 3, the furnace body 1 is provided with an inner cavity; the two heating assemblies 2 are movably arranged on both sides of the inner cavity, and the two heating assemblies 2 form a forming channel with a spacing, and the side of the heating assembly 2 facing the forming channel is provided with a heating wire 25; the adjusting assembly 3 is connected to the heating assembly 2, and the adjusting assembly 3 is used to drive the heating assembly 2 to move away from or approach the forming channel. By arranging the two heating assemblies 2 movably connected on both sides of the inner cavity, when the glass ribbon 5 swings due to equipment stability or other reasons, causing the glass ribbon 5 to adhere to the heating wire 25, the position of the heating assembly 2 is adjusted by the adjusting assembly 3, the spacing between the two heating assemblies 2 is expanded, the length of the forming channel between the two heating assemblies 2 is lengthened, and the sticking point deviates from the center position.
