[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0031] Specific implementation examples are given below.

[0032] Please see Figures 1 to 4 This utility model provides an overflow-method glass traction forming apparatus, comprising: a forming furnace assembly 10, a heat exchange assembly 20, a guide assembly 30, a conveying roller assembly 40, and a cooling assembly 50. The heat exchange assembly 20 is disposed below the outlet of the forming furnace assembly 10. The guide assembly 30 is located on the side of the heat exchange assembly 20 away from the forming furnace assembly 10. The conveying roller assembly 40 is disposed below the guide assembly 30. The cooling assembly 50 is disposed above the conveying roller assembly 40, and a gap exists between the cooling assembly 50 and the conveying roller assembly 40.

[0033] Through the above technical solution, the molten glass provided in this application flows down from the forming furnace assembly 10, the temperature of the molten glass is controlled by the heat exchange assembly 20, the direction of movement of the molten glass (the glass to be formed with a higher temperature) is changed by the guide assembly 30, the conveying roller assembly 40 conveys the glass to be formed, and the cooling assembly cools the glass to be formed. This structure greatly reduces the requirements for operation. The technical solution of this embodiment effectively solves the problem of high skill requirements for operators in the overflow glass processing of the prior art.

[0034] It should be noted that the conveyor roller assembly 40 is located below the guide assembly 30, meaning that the center of the guide assembly 30 is lower than the conveyor roller assembly 40.

[0035] like Figure 1 and Figure 3 As shown, in some embodiments, the guiding assembly 30 includes a guide block 31 and a steering roller 32. The guide block 31 and steering roller 32 have a gap in the horizontal direction. The side of the guide block 31 facing the steering roller 32 is arc-shaped, with the absolute value of the arc slope gradually decreasing. The cooperation of the guide block 31 and the steering roller 32 enables the high-temperature glass to be formed to be rotated from a vertical direction to a horizontal direction, facilitating the next process. The arc-shaped side of the guide block 31 facing the steering roller 32, with the absolute value of the arc slope gradually decreasing, results in a gentler force on the glass to be formed. The rotation of the steering roller 32 causes the friction between the glass to be formed and the steering roller 32 to be rolling friction, greatly reducing the force between them. It should be noted that the width of both the guide block 31 and the steering roller 32 is greater than the width of the glass. The absolute value of the arc slope at the very end of the guide block 31 is close to zero or almost zero, meaning the end is nearly horizontal.

[0036] like Figure 3 As shown, in some embodiments, the guide assembly 30 includes a guide block mounting bracket and two fixing pins. The guide block mounting bracket is equipped with a dovetail slide rail, and the guide block 31 has a dovetail groove adapted to the dovetail slide rail. First fixing pin holes are respectively provided on both sides of the guide block 31, and the guide block mounting bracket has two rows of second fixing pin holes, with multiple second fixing pin holes in each row. The mating structure of the dovetail slide rail and the dovetail groove makes the movement of the guide block 31 smoother and more precise. The first fixing pin holes, second fixing pin holes, and fixing pins fix the position of the guide block 31. The multiple second fixing pin holes improve the versatility of the guide assembly 30, allowing it to be adapted to the processing of different types of glass.

[0037] like Figure 1 As shown, in some embodiments, the conveyor roller assembly 40 includes a conveyor roller mounting frame and multiple conveyor rollers. The multiple conveyor rollers are rotatably mounted on the conveyor roller mounting frame, and the guide roller 32 is rotatably mounted on the conveyor roller mounting frame. The conveyor roller mounting frame facilitates the installation of the multiple conveyor rollers. The multiple conveyor rollers cooperate with the glass for conveying, greatly reducing the friction between the glass and the conveyor rollers, reducing unevenness on the glass surface, and improving the quality of the glass. It should be noted that the conveyor roller assembly 40 is located on the side facing the guide block.

[0038] like Figure 1As shown, in some embodiments, the cooling assembly 50 includes multiple cooling rollers, all rotatably mounted on a conveyor roller mounting frame and located above the conveyor roller assembly 40. Each cooling roller has a cooling water jacket. The arrangement of multiple cooling rollers improves the cooling efficiency of the glass, reduces the process length of the overflow glass traction forming apparatus, and thus reduces the footprint of the overflow glass traction forming apparatus. Through process control, the cooling temperature of the multiple cooling rollers decreases sequentially in the direction of glass movement. It should be noted that the cooling assembly 50 also includes multiple temperature measuring structures, which are arranged one-to-one with the multiple cooling rollers.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the heat exchange assembly 20 includes a heating structure 21 and a cooling structure 22, with the heating structure 21 located above the cooling structure 22. This structure allows for diverse selection; the heating structure 21 can be used alone, the cooling structure 22 can be used alone, or both can be used simultaneously. It should be noted that the simultaneous use of the heating structure 21 and the cooling structure 22 can be adjusted as needed. The heat exchange assembly 20 includes multiple temperature measurement structures, which are respectively disposed on both sides of the glass and correspond to the heating structure 21 and the cooling structure 22. Specifically, the heat exchange assembly 20 has at least four temperature measurement structures (temperature sensors in this case), with at least two on each side of the glass, at least one corresponding to the heating structure 21 on one side and at least one corresponding to the cooling structure 22 on the other side.

[0040] like Figure 4 As shown, in some embodiments, the heating structure 21 includes a heating shell and a resistance wire, with the resistance wire disposed inside the heating shell. This structure offers faster heating and easier control.

[0041] like Figure 4 As shown, in some embodiments, the cooling structure 22 includes a cooling housing with a coolant inlet and a coolant outlet. This structure is safe, reliable, and easy to control.

[0042] like Figure 4 As shown, in some embodiments, the heating shell and cooling shell are integrated heat exchange shells, with two shells located on either side of the molten glass. The distance between the two heat exchange shells gradually decreases from top to bottom. This structure is designed based on the thickness characteristics of the glass to be formed, and it facilitates full utilization of energy, improving heating and cooling efficiency.

[0043] According to another aspect of this application, an overflow glass production apparatus is also provided, which includes an overflow glass traction forming device, wherein the overflow glass traction forming device is the aforementioned overflow glass traction forming device.

[0044] The embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0045] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this application.
