Problems solved by technology
In the prior art, the existing rear annealing air duct in the bending furnace is an S-shaped air duct, and the S-shaped annealing air duct is provided with a tuyere. Such a design cannot effectively anneal the baked and bent glass. As a result, the edge stress of the glass cannot reach the value stipulated in the relevant standards, and some glass cracks appear during the installation and use of the glass after delivery.

The invention belongs to the field of glass annealing devices, and in particular discloses an automatic annealing box of a hot bending furnace. The automatic annealing box comprises a plurality of hot air branch pipes and an air inlet, wherein a plurality of rollers are arranged below the hot air branch pipes; two ends of the hot air branch pipes are bent and wound to form a box body shell; a plurality of first hot air holes are formed in an inner wall of the box body shell at intervals; air outlets are formed in the other ends of the hot air branch pipes, and the air outlets are provided with air outlet pipes; the air outlet pipes are connected with a turbine; the turbine is provided with a ventilation pipe; the rollers are connected with the turbine through the ventilation pipe; the rollers are provided with a plurality of second hot air holes at intervals. According to the automatic annealing box disclosed by the invention, an upper surface and a lower surface of glass bent by baking are annealed simultaneously under the combined effects of the first hot air holes and the second hot air holes.
Description
technical field [0001] The invention relates to the field of glass annealing box devices. Background technique [0002] The stress index in the field of glass manufacturing is one of the important indicators to measure the quality of glass. Generally speaking, the smaller the stress, the better the performance of the product. In the prior art, the existing rear annealing air duct in the bending furnace is an S-shaped air duct, and the S-shaped annealing air duct is provided with a tuyere. Such a design cannot effectively anneal the baked and bent glass. As a result, the edge stress of the glass cannot reach the value stipulated in the relevant standards, and some glass cracks appear during the installation and use of the glass after delivery. Contents of the invention [0003] The present invention intends to provide an automatic annealing box of a bending furnace which anneals the upper and lower surfaces of the bent glass and can be automatically transported. [0004]...
