[0036] Embodiment 1

[0037] like Figures 1 to 3 As shown, the present invention provides a synchronous swing air grille for glass tempering, comprising a frame 10, an upper air grille 20, a lower air grille 30, a lifting mechanism 60, a synchronization component 50, and a reciprocating drive mechanism 40; a roller 70 for conveying glass is arranged between the upper air grille 20 and the lower air grille 30; the lifting mechanism 60 is arranged on the frame 10 and is non-rigidly connected to the upper air grille 20 and the lower air grille 30; the upper air grille 20 is connected to the lower air grille 30 through the synchronization component 50; the reciprocating drive mechanism 40 is arranged on the frame 10 and is connected to the synchronization component 50; the reciprocating drive mechanism 40 drives the synchronization component 50 to drive the upper air grille 20 and the lower air grille 30 to perform synchronous reciprocating motion along the conveying direction perpendicular to the roller 70.

[0038] In this embodiment, the synchronization component 50 is used to drive the upper wind grille 20 and the lower wind grille 30 to swing synchronously and reciprocally in a direction perpendicular to the movement direction of the glass, so that the upper and lower surfaces of the glass are exposed to wind without dead angles, the wind is exposed more evenly, wind spots are effectively reduced, and the quality of tempered glass is improved.

[0039] like Figure 3 As shown, the synchronization component 50 includes two groups of sliders 51 and a plurality of optical axes 52. One end of one group of sliders 51 is fixedly connected to the upper wind grille 20, and one end of the other group of sliders 51 is fixedly connected to the lower wind grille 30. The two groups of sliders 51 are slidably connected to the plurality of optical axes 52, thereby ensuring that the wind grille does not interfere with the reciprocating drive mechanism when performing lifting and lowering movements.

[0040] like Figure 3 As shown, the reciprocating drive mechanism 40 includes a push-pull assembly A41, a swing assembly 42, and an eccentric assembly 43. The push-pull assembly A41 is connected to the synchronous assembly 50; one end of the swing assembly 42 is connected to the end of the push-pull assembly A41 away from the synchronous assembly 50, thereby driving the push-pull assembly A41 to perform linear reciprocating motion; one end of the eccentric assembly 43 is connected to the other end of the swing assembly 42, and drives the other end of the swing assembly 42 to perform circular motion. The swing assembly is driven to swing by the eccentric assembly, and then the push-pull assembly is driven to realize the reciprocating motion of the upper and lower air grilles. The mechanism runs more smoothly and has a compact structure.

The rotating shaft 431 is arranged on the frame 10 through a bearing seat, and the rotating shaft 431 rotates around its axis; one end of the eccentric rod 432 is eccentrically arranged on the end surface of the rotating shaft 431 close to one end of the swing assembly 42, and rotates around the axis of the rotating shaft 431; the other end of the eccentric rod 432 is connected to the swing assembly 42. Optionally, the rotating shaft can be a split structure, including a short shaft and a rotating wheel arranged at one end of the short shaft, and the eccentric rod 432 can be fixed to the end surface of the rotating wheel.

[0043] like Figure 1 and Figure 2 As shown, the lifting mechanism 60 is a screw lifting mechanism, and the screw lifting mechanism is connected to the upper air grille 20 and the lower air grille 30 in a non-rigid manner through a chain, so as to ensure that the air grille does not interfere with the lifting mechanism in lateral swing. In this embodiment, there are two lifting mechanisms 60, which are respectively connected to the upper air grille 20 and the lower air grille 30. Optionally, the lifting mechanism 60 can also be a chain lifting mechanism, one end of the chain lifting mechanism is connected to the upper air grille 20, and the other end is connected to the lower air grille 30. By driving the chain, the upper air grille 20 and the lower air grille 30 are moved closer to or away from each other. In addition to using a chain to achieve a non-rigid connection between the air grille and the lifting mechanism, a universal joint or the like can also be used to ensure that the air grille can be raised and lowered and can also swing laterally independently.

[0044] like Figure 3 As shown, in order to ensure that the force and swing of the upper air grille 20 and the lower air grille 30 are more uniform, the two reciprocating drive mechanisms 40 in this embodiment are respectively connected to the upper air grille 20 and the lower air grille 30 through a synchronization component 50. The two reciprocating drive mechanisms 40 and the synchronization component 50 constitute a drive assembly. The drive assemblies are divided into two and are evenly arranged to make the driving force more uniform, and the stability and durability of the device are good.

[0045] The two drive assemblies consisting of four reciprocating drive mechanisms 40 are connected to the same power transmission assembly 80 to achieve synchronous motion. The power transmission assembly 80 includes a motor 81, a transmission shaft 46, a transmission sprocket 82, and a chain 83. The transmission sprocket 82 includes a sprocket arranged on the rotating shaft of the eccentric assembly 43. One chain 83 can transmit power by driving multiple sprockets arranged on the rotating shaft of the eccentric assembly 43, and finally achieve the purpose of one motor 81 providing power and multiple reciprocating drive mechanisms 40 acting synchronously.

[0046] Optionally, there are multiple reciprocating drive mechanisms 40 and synchronization components 50, and they are connected one-to-one to simplify the structure of the whole machine. The corresponding number of groups can be flexibly selected, and finally the same power transmission component 80 is used to achieve the synchronous movement of multiple reciprocating drive mechanisms 40.

[0047] Embodiment 2

[0048] like Figures 4 to 8 As shown, the main difference between this embodiment and the first embodiment is that the reciprocating drive mechanism 40 is different.

The push-pull component B44 is connected to the synchronization component 50; one end of the dial wheel and lever component 45 is connected to the transmission shaft 46, and the other end is connected to one end of the push-pull component B44, thereby driving the push-pull component B44 to perform linear reciprocating motion.

[0051] The working principle of the reciprocating drive mechanism 40 in this embodiment is that the lever 452 is inserted into the push head 441 with a groove, and the dial wheel is driven by the transmission shaft 46 to rotate, thereby driving the lever 452 to rotate, and the pull rod B442 is driven to move by the lever 452, thereby driving the push-pull assembly B44 to reciprocate. Preferably, the surface of the lever 452 can also be sleeved with a freely rotatable sleeve or bearing, so as to reduce the hard friction between the lever 452 and the push head 441.

[0052] like Figure 6 As shown, multiple reciprocating drive mechanisms 40 are connected to the same power transmission assembly 80 to achieve synchronous movement. In this embodiment, the power transmission assembly 80 includes a motor 81, a transmission sprocket 82, and a chain 83 arranged on a frame. Through a power input, multiple transmission shafts 46 are driven to rotate, thereby achieving synchronous driving of multiple reciprocating drive mechanisms 40.
