[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0017] Flat glass tempering unit, such as Figs. 1 to 3 As shown, the tempered glass heating box 1 includes a conveying platform 2 installed inside the tempered glass heating box 1, and an upper air grid 3 and a lower air grid 4 are installed on the upper and lower parts of the conveying platform 2 respectively. The upper air grid 3 and the lower air grid 4 are connected to the fan respectively. A bracket 5 is also provided inside the tempered glass heating box 1, and a driving mechanism for driving the upper air grid 3 and the lower air grid 4 to move up and down is installed on the upper and lower parts of the bracket 5 respectively.

[0018] The driving mechanism includes a worm gear 7 mounted on a bracket 5, which is connected to a worm 6 arranged on one side of the bracket 5. A screw 8 is installed on the center thread of the worm gear 7, and one end of the screw 8 is connected to the upper air grille 3 or the lower air grille 4.

[0019] The air outlets of the upper air grille 3 and the lower air grille 4 are multiple strip-shaped air outlets arranged in parallel.

[0020] The worm 6 is mounted on the bracket 5 via the mounting bracket 11 and one end of the worm 7 is connected to the rotating motor.

[0021] A guide assembly is installed between the conveying platform 2 and the upper air grille 3 or the lower air grille 4. The guide assembly includes guide columns 9 installed on both sides of the conveying platform 2. The guide columns 9 are slidably fitted with limit rings 10 provided on the upper air grille 3 or the lower air grille 4.

[0022] A number of conveying rollers are installed on the conveying platform 2. The conveying threads on adjacent conveying rollers are opposite to each other, which can ensure that the glass moves repeatedly on the conveying platform 2 and prolong the heating time.

Then the glass is driven to move by the conveying platform 2. However, due to the conveying threads of the adjacent conveying rollers on the conveying platform 2, the glass will move repeatedly on the conveying platform 2, which prolongs the heating time and ensures the uniformity of heating.

[0025] The utility model provides a flat glass tempering unit. By arranging a driving mechanism for driving the upper and lower air grilles to move up and down to adjust the distance between the upper and lower surfaces of the glass, the unit can be suitable for tempering glass of different thicknesses. At the same time, it ensures that the upper and lower surfaces of the glass are evenly exposed to wind, reduces the possibility of glass deformation, and improves the tempering efficiency of the glass.
