Tempering furnace and production line

Abstract

This utility model discloses a tempering furnace and production line. The tempering furnace is used for processing glass and includes a furnace body, a furnace door, a first drive unit, and a second drive unit. The furnace body has a cavity and an opening communicating with the cavity, the opening for glass to enter and exit the cavity. The furnace door is movably connected to the furnace body and has a first position and a second position relative to the furnace body. In the first position, the furnace door covers the opening. In the second position, the opening is exposed relative to the furnace door. The first drive unit is connected to the furnace door and is used to drive the furnace door to switch between the first and second positions. The second drive unit is connected to the furnace door and is capable of driving the furnace door to switch from the first position to the second position. This solution can effectively avoid the situation where the furnace door cannot be opened normally, causing glass to remain in the furnace body, effectively improving the emergency response capability of the furnace door in the event of a failure of the first drive unit, ensuring the continuity and stability of glass processing, and improving the quality of glass processing.
