Description

technical field

[0001] The invention relates to an annealing furnace, in particular to a glass lens annealing furnace. Background technique

[0002] The glass lens needs to be placed in an annealing furnace for hot pressing after hot pressing. Since the initial temperature of the glass lens after hot pressing is 300°C to 400°C, slow annealing is required. The temperature in the existing annealing furnace is constant, which is not conducive to improving the annealing efficiency. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a glass lens annealing furnace, which can anneal in stages and improve the annealing efficiency.

[0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

[0005] A glass lens annealing furnace, comprising a furnace body, a mesh belt is arranged in the furnace body, and the mesh belt is installed on a driving wh...

Embodiment Construction

[0020] Such as Figure 1-4 Shown, a kind of glass lens annealing furnace comprises frame 27, is provided with furnace body 1 on frame 27, is provided with mesh belt 2 in body of furnace 1, and mesh belt 2 is installed on the driving wheel 3 on the frame 27 front and rear, On driven wheel 4. The driving wheel 3 is directly or indirectly driven by a motor. In order to realize the step change of temperature in the furnace body 1 , a plurality of isolation mechanisms 10 can be arranged in the furnace body 1 . The isolation mechanism 10 comprises a pair of partitions 11 arranged in the furnace body 1, a certain space is provided between the partitions 11 for the baffles 13 to pass through, and the pair of partitions 11 are all provided with ventilation holes 12. When 13 moves up and down, the ventilation hole 12 is opened or closed so as to realize air circulation in the furnace body 1 . In order to ensure the insulation performance, the gap between the lower end of the partitio...
