Glass tempering furnace

Abstract

The invention discloses a glass tempering furnace which comprises a furnace body. A ceramic roller bed is arranged in a hearth; glass is movably arranged on the ceramic roller bed; tempering operationdevices are symmetrically arranged on two sides of the glass; each tempering operation device comprises a slide rail rod; movable rods are movably arranged on the slide rail rods; a radiant panel isfixedly arranged between the movable rods; a connecting block is fixedly connected to the center of a gear; the gear is movably arranged on a rack; multiple support pillars are fixedly arranged on a support plate; a heating wire plate is fixedly arranged on the support pillars. According to the glass tempering furnace provided by the invention, the spaces between a heating wire and glass as well as between the radiant panel and the glass can be adjusted, so that the temperature adjustment speed is fast, and the tempering requirements of different glass can be met; meanwhile, a built-in ceramicroller bed cleaning device can be used for cleaning without disassembling a roller bed, and the fact that foreign matters attached onto the roller bed at high temperature form pocking marks on the glass is avoided, so that the tempering quality is improved.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a glass tempering furnace. Background technique [0002] In the traditional glass tempering furnace, each heating element is evenly arranged near the upper and lower surfaces of the glass, and the heat is mainly transferred to the surface of the glass by radiation to heat the glass. The distance between the glass and the heating wire is fixed, resulting in For different glasses, only the temperature of the furnace wire can be controlled to control the temperature radiated to the glass, but when the temperature of the furnace wire cannot be lowered or raised in time when the temperature of the furnace wire is adjusted, the tempering of the glass will be affected; at the same time, Because foreign matter will adhere to the rollers in a high-temperature environment, pitting will appear on the high-temperature glass after passing through the rollers. Therefore, the roller ta...

AI Technical Summary

Problems solved by technology

[0004] However, there are still obvious defects in its use: 1. The distance between the heating device and the glass is fixed and cannot be adjusted. For different glasses, the radiation to the glass can only be controlled by controlling the temperature of the heating furnace wire. However, when the temperature on the heating furnace wire cannot be cooled or raised in time, it will affect the tempering efficiency of the glass; 2. There is no device for cleaning the ceramic roller table that drives the glass to move, and foreign objects will adhere to the roller table under high temperature conditions. On the shaft, the high-temperature glass will appear pitting after passing through the roller, which will affect the quality of the glass
