Description

Technical Field

[0001] The utility model belongs to the technical field related to independent transmission devices for transition rollers of borosilicate float glass, and particularly relates to an independent transmission device for transition rollers of borosilicate float glass. Background Art

[0002] The independent transmission device for the transition roller of borosilicate float glass is a key equipment used in the glass production process. It is mainly used to achieve a smooth transition of glass sheets during the glass melting and forming process. The device controls the movement of the roller through an independent transmission system to ensure that the glass maintains uniform thickness and surface quality during the cooling and solidification process. Its design usually includes high-precision sensors and control systems to monitor and adjust the speed and position of the roller in real time, thereby improving production efficiency and product quality.

[0003] The transition roller table is a device that connects the two major thermal processes of tin bath and annealing. It is a very critical stage for the glass to gradually change from a plastic free state to an elastic frozen state. In actual production, after accidents such as kiln baking, high-temperature production, tin consumption, lead and broken plate, the actual transition curve of the transition roller table does not match the set curve, which may affect the internal stress structure and external surface performance quality of the glass, affect the forming and annealing of float glass, and lead to a reduction in the yield rate.
