[0028] Embodiment 1:

[0029] As Figures 1 - 3 shown, the present utility model provides an air duct assembly for mixing float glass, including: an air outlet duct 10, a baffle 20, and an adjusting mechanism. The air outlet duct 10 is provided with an air outlet. The baffle 20 is disposed inside the air outlet duct 10. The baffle 20 is adapted to divide the inner cavity of the air outlet duct 10 into a first channel and a second channel. The first channel and the second channel are axially isolated from each other in the air outlet duct. The baffle 20 is provided with a plurality of air holes 21 adapted to communicate the first channel with the second channel. The first channel is communicated with the air outlet. The adjusting mechanism has a movable part. The movable part is movably disposed inside the second channel. The movable part moves to open or close the plurality of air holes 21; wherein at least a part of the movable part axially abuts against the baffle 20.

[0030] In some embodiments, a fluid passage extending axially is provided in the air outlet duct 10, and an air outlet and an air inlet are respectively provided at both ends of the air outlet duct 10 in the axial direction. The baffle 20 is disposed in the fluid passage and is adapted to divide the fluid passage into a first passage and a second passage. The first passage and the second passage are isolated from each other axially. The first passage communicates with the air outlet, and the second passage communicates with the air inlet. A plurality of air holes 21 penetrating axially are further provided on the baffle 20. The plurality of air holes 21 are respectively adapted to communicate the first passage and the second passage. The adjusting mechanism is disposed in the second passage. The adjusting mechanism has a movable part, and at least part of the movable part abuts against the baffle 20 axially. The movable part moves to control the opening or closing of the plurality of air holes 21. When the projection of the movable part on the air hole 21 in the axial direction overlaps, the corresponding air hole 21 is blocked by the movable part (the corresponding air hole 21 is in a closed state). At this time, the cooling gas cannot pass through the corresponding air hole 21. When the projection of the movable part on the air hole 21 in the axial direction is misaligned with each other, the corresponding air hole 21 is in an open state. At this time, the cooling gas can pass through the corresponding air hole 21.

[0031] It should be noted that rotation is a subordinate concept of movement (rotation is movement microscopically). Thus, the movable part can simply move in the second passage to control the opening or closing of the plurality of air holes 21. The movable part can also rotate in the second passage to control the opening or closing of the plurality of air holes 21, and no limitation is made here.

[0032] For example, the movable part can be simply a wind baffle. The wind baffle moves radially along the air outlet duct 10 to control the opening or closing of the plurality of air holes 21. At the same time, the wind baffle can also rotate around a certain point to control the opening or closing of the plurality of air holes 21. Of course, the movable part can also be a folding plate. The folding plate rotates around the central axis of the air outlet duct 10 and deforms to control the opening or closing of the plurality of air holes 21, and no limitation is made here.

[0033] It can be understood that at least part of the baffle 20 abuts against the movable part axially (here, part or all of the part where the projection of the movable part on the baffle 20 in the axial direction overlaps can abut against the baffle 20, and no limitation is made here). Thus, when the cooling gas enters the second passage from the air inlet and blows to the adjusting mechanism, the baffle 20 can support the movable part, thereby improving the setting stability of the movable part, avoiding excessive deformation or even damage of the movable part, improving the service life and working stability of the movable part, and thus improving the service life and working stability of the air duct assembly.

[0034] It is worth mentioning that the adjusting mechanism can control the number of opened air holes 21 on the baffle 20 to adjust the gas flow rate from the second channel to the first channel, thereby controlling the amount of cooling gas discharged from the air outlet, and further realizing the control and adjustment of the temperature during mixing. During the mixing process of float glass, the raw materials are melted at high temperature. In order to control the temperature of the molten materials, it is necessary to introduce cooling gas. Therefore, in this application, by controlling the opening and closing number of the air holes 21 through the adjusting mechanism, the amount of cooling gas entering the mixing area can be accurately adjusted.

[0035] It should be noted that when more air holes 21 are opened, more cooling gas is introduced, thereby accelerating the heat dissipation in the mixing area and reducing the temperature of the molten materials; on the contrary, if the opening number of the air holes 21 is reduced, the inflow of cooling gas will be reduced and the cooling rate will be slowed down.

[0036] In particular, when the cooling gas passes through the baffle 20, it will become a stream of airflows, increasing the pressure and flow rate of the cooling gas, so that the air duct assembly has a better cooling effect on the mixing area.

[0037] In some embodiments, a plurality of air passing channels are provided on the side of the baffle 20 facing away from the adjusting mechanism. The plurality of air passing channels correspond to and communicate with the plurality of air holes 21 one by one, and the diameters of the plurality of air passing channels gradually decrease in the direction away from the adjusting mechanism. Thus, the plurality of air passing channels can increase the pressure of the passing cooling gas and can increase the speed of the passing cooling gas, thereby improving the cooling effect on the mixing area.

[0038] According to the air duct assembly for mixing float glass of the present utility model, by providing a baffle 20 and an adjusting mechanism that axially abut against each other in the air outlet pipe 10, and the adjusting mechanism moves to selectively control the opening or closing of a plurality of air holes 21, the baffle 20 can support the movable part to resist the stress of the cooling gas on the movable part, improving the setting stability of the movable part, thereby improving the working stability of the adjusting mechanism, and further improving the stability of the air volume control. At the same time, through the above settings, the service life of the adjusting mechanism can also be extended, thereby extending the service life of the air duct assembly.

[0039] Embodiment Two:

[0040] Based on Embodiment One, the movable part of the adjusting mechanism in this embodiment includes: a folding plate 30. The folding plate 30 has a plurality of second wind baffle plates 32. The side walls of the plurality of second wind baffle plates 32 are connected to each other, and creases are formed between adjacent two second wind baffle plates 32. The plurality of second wind baffle plates 32 together constitute an adjusting plate; wherein the adjusting plate is circumferentially distributed around the central axis of the second channel, and the second wind baffle plates 32 are relatively folded to adjust the projected area of the adjusting plate in the axial direction of the second channel.

[0041] According to some embodiments of the present utility model, the folding plate 30 further includes: a first wind baffle 31, both ends of the first wind baffle 31 are respectively connected to the baffle 20 and one end of the adjusting plate, and the one end of the adjusting plate moves relative to the baffle 20; a third wind baffle 33, the third wind baffle 33 is rotatably connected to the other end of the adjusting plate, the third wind baffle 33 is slidably connected to the baffle 20, the third wind baffle 33 moves circumferentially around the central axis of the second channel, and the third wind baffle 33 applies pressure to a part of the second wind baffle 32, and the folding state of the second wind baffle 32 is adjusted by the third wind baffle 33.

[0042] It can be understood that the folding plate 30 can move circumferentially around the central axis of the second channel. Thus, the folding plate 30 can rotate or move in a direction perpendicular to the air flow, and the deformability of the folding plate 30 allows the folding plate 30 itself to change its shape during the movement, so as to change the projected area of the folding plate 30 in the axial direction, and further indirectly control the number of air holes 21 opened on the baffle 20, thereby realizing the control of the air volume discharged from the air outlet.

[0043] When the projected area of the folding plate 30 increases, the folding plate 30 can block more air holes 21, thereby reducing the air flow, and further reducing the air volume discharged from the air outlet; conversely, when the projected area decreases, more air holes 21 are opened, thereby increasing the air flow, and further increasing the air volume discharged from the air outlet.

[0044] It is worth noting that when the folding plate 30 moves and deforms in the second channel, at least a part of the folding plate 30 is always axially abutted against the baffle 20. Thus, the folding plate 30 can be supported by the baffle 20 when folding or unfolding, thereby improving the setting stability of the folding plate 30 during operation, and further enabling the folding plate 30 to have good anti-deformation ability when folding or unfolding, and extending the service life of the folding plate 30.

[0045] The folding plate 30 includes: a first wind baffle 31, a second wind baffle 32 and a third wind baffle 33. The first wind baffle 31 is connected to the baffle 20. The second wind baffle 32 is multiple, the side walls of the multiple second wind baffles 32 are connected to each other, and there is a crease formed between two second wind baffles 32. Thus, the multiple second wind baffles 32 are rotatably connected to each other in their own width direction. The multiple second wind baffles 32 together form an adjusting plate. One end of the adjusting plate is rotatably connected to the first wind baffle 31, the third wind baffle 33 is rotatably connected to the other end of the adjusting plate, the third wind baffle 33 is slidably connected to the baffle 20, the third wind baffle 33 moves circumferentially around the central axis of the second channel, and the third wind baffle 33 applies pressure to a part of the second wind baffle 32, so as to drive at least a part of the second wind baffle 32 to move and deform.

[0046] In some embodiments, the first wind deflector 31 is the basis of the folding plate 30 structure. The first wind deflector 31 is directly connected to the baffle 20 to serve as the anchor point of the entire folding plate 30 system, and is the basis for the connection and deployment of other wind deflectors. The second wind deflectors 32 are configured in multiple numbers. The multiple second wind deflectors 32 are connected to each other in their own width directions to form an adjustment plate. The adjustment plate is in a structure similar to an accordion or a folding fan. One end of the adjustment plate is connected to the first wind deflector 31, and the other end of the adjustment plate is connected to the third wind deflector 33.

[0047] The third wind deflector 33 is slidably connected to the baffle 20, and the third wind deflector 33 can selectively move circumferentially around the central axis of the first channel. When the third wind deflector 33 moves, the second wind deflector 32 will stretch or fold accordingly, thereby changing the projected area of the entire folding plate 30 in the axial direction, and further adjusting the number of air holes 21 opened on the baffle 20, so as to adjust the size of the air volume discharged from the air outlet.

[0048] It should be noted that the first wind deflector 31, the second wind deflectors 32, and the third wind deflector 33 can be made of materials such as engineering plastics or aluminum, as long as the first wind deflector 31, the second wind deflectors 32, and the third wind deflector 33 have a certain ductility. After the first wind deflector 31 and the second wind deflector 32 are connected, they form a structure similar to a hinge; after two adjacent second wind deflectors 32 are connected, they form a structure similar to a hinge; after the second wind deflector 32 and the third wind deflector 33 are connected, they form a structure similar to a hinge.

[0049] It should be noted that during the unfolding or contraction of the folding plate 30, both the first wind deflector 31 and the third wind deflector 33 are in an axially abutting relationship with the baffle 20. The second wind deflector 32 has a small deformation near the central axis of the second channel, that is, the second wind deflector 32 is always in an axially abutting relationship with the baffle 20 near the central axis of the second channel. Thus, during the unfolding or contraction of the folding plate 30, the baffle 20 can support the first wind deflector 31, the second wind deflectors 32, and the third wind deflector 33, improving the setting stability of the first wind deflector 31, the second wind deflectors 32, and the third wind deflector 33, and thereby extending the service life of the first wind deflector 31, the second wind deflectors 32, and the third wind deflector 33.

[0050] Embodiment Three:

[0051] Based on Embodiment Two, the adjustment mechanism of this embodiment further includes: a mounting bracket and a rotating ring 41. The mounting bracket is connected to the air outlet pipe 10, the rotating ring 41 is rotatably connected to the mounting bracket, and the rotating ring 41 is fixedly connected to the third wind deflector 33.

[0052] It can be understood that the mounting bracket is a fixed component of the adjusting mechanism. The mounting bracket plays a role in supporting and positioning, thereby ensuring that the entire adjusting mechanism is stably connected to the air outlet pipe 10. The mounting bracket is directly connected to the air outlet pipe 10, and the mounting bracket can provide a stable base for the rotating ring 41, enabling the rotating ring 41 to rotate reliably around its axis. The rotating ring 41 is fixedly connected to the third wind deflector 33, and the rotation of the rotating ring 41 can drive the movement of the third wind deflector 33.

[0053] When the rotating ring 41 rotates, the rotating ring 41 will drive the third wind deflector 33 fixedly connected thereto to rotate together. The rotation of the third wind deflector 33 will drive the extension or folding of multiple second wind deflectors 32, thereby changing the projected area of the folding plate 30 in the axial direction.

[0054] Embodiment Four:

[0055] Based on Embodiment Three, a first tooth portion 411 is provided on the outer peripheral wall of the rotating ring 41. The adjusting mechanism further includes: an adjusting rod 42, and the adjusting rod 42 is provided with a second tooth portion 421 that cooperates with the first tooth portion 411. At least a part of the adjusting rod 42 extends radially outside the second channel.

[0056] It can be understood that the second tooth portion 421 is provided on the adjusting rod 42, and the second tooth portion 421 matches the first tooth portion 411 of the rotating ring 41, that is, the second tooth portion 421 can mesh with the first tooth portion 411 to form a gear transmission system. Thus, the movement of the adjusting rod 42 can drive the rotation of the rotating ring 41, and the rotation of the rotating ring 41 can drive the movement of the third wind deflector 33 fixed thereto, thereby adjusting the shape of the folding plate 30.

[0057] It is worth noting that one end or part of the adjusting rod 42 is designed to extend outside the first channel. Thus, the operator can contact the adjusting rod 42 from the outside, and the operation can be performed without directly entering the inside of the air duct, which facilitates the operator to adjust the air volume of the air duct assembly.

[0058] According to some embodiments of the present invention, a plurality of positioning holes 422 are provided on the adjusting rod 42. The plurality of positioning holes 422 are spaced apart in the extending direction of the adjusting rod 42. A fixing pin is movably provided on the outer peripheral wall of the air outlet pipe 10, and the fixing pin can selectively cooperate with one of the positioning holes 422 to fix the adjusting rod 42.

[0059] It can be understood that each positioning hole 422 represents a specific adjustment position, corresponding to different air flow adjustment states. By mating the fixing pin with the positioning hole 422, the operator can ensure that the adjusting rod 42 remains in the desired position, thus maintaining the stability of the air volume adjustment and avoiding accidental changes from affecting the production process. Thus, the operator only needs to insert the fixing pin into the corresponding positioning hole 422 to quickly achieve the preset air flow adjustment, without the need for repeated fine-tuning, saving time and effort.

[0060] Embodiment Five:

[0061] Based on Embodiment Three of the present invention, the baffle 20 is provided with an annular chute 22, and a slider is provided on the side of the third wind baffle 33 facing the baffle 20. The slider is movably received in the chute 22. It can be understood that the outer peripheral wall of the chute 22 can limit at least part of the inner peripheral wall of the slider, so that the slider can stably move along the extending direction of the chute 22, and further make the movement of the third wind baffle 33 more stable.

[0062] According to some embodiments of the present invention, the inner peripheral wall of the second channel is provided with a limiting groove extending in the circumferential direction, and one end of the folding plate 30 away from the central axis of the second channel is movably disposed in the limiting groove. It can be understood that the inner peripheral wall of the limiting groove can limit at least part of the outer peripheral wall of the folding plate 30, so that the folding or contraction of the folding plate 30 is more stable, improving the stability of the air volume control. Of course, the inner peripheral wall of the limiting groove can also support the folding plate 30, thereby improving the anti-deformation ability of the folding plate 30.

[0063] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
