Description

Technical Field

[0001] The utility model relates to the technical field of bent glass tempering, in particular to a connection structure of a flexible shaft bent-shaped keel. Background Art

[0002] The existing technology is to arrange the arc-changing dragon on the two end faces of the forming keel, connect the arc-changing dragon and the end face of the forming keel by bolts, and use the arc-changing action of the arc-changing dragon to drive the forming keel to form the target curved surface.

[0003] The forming keel is equipped with a flexible shaft unit and a nozzle unit, which is quite heavy. When the keel length exceeds a certain length, the deflection of the forming keel increases due to the influence of gravity, which easily exceeds the arc change accuracy requirements of the equipment. Therefore, under the current end-face installation method, the forming keel length of the flexible shaft bending equipment is mostly no more than 7 meters. In the ultra-long curved wind grille equipment, more forming keels and arc change keel units are required, which makes installation and control cumbersome.

[0004] Moreover, in the super-long curved wind grid equipment, the forming wind grid needs to be arranged in sections. Since two arc-changing dragon units are arranged between adjacent forming keels, air nozzles cannot be set on the arc-changing dragon units, and the continuity of the air blowing from the air nozzles cannot be guaranteed, which causes uneven cooling and affects the quality of the processed glass. Utility Model Content

[0005] The purpose of the utility model is to propose a connection structure of a flexible shaft bent forming keel, which can extend the length of the forming keel while ensuring deflection, thereby realizing an ultra-long wind grid with continuous blowing; in the ultra-long bent wind grid equipment, the uniformity of the blowing can be guaranteed.

[0006] The technical solution adopted by the utility model is: a connection structure of a flexible shaft bending forming keel, wherein the upper surface of the forming keel is provided with a first roller and an air nozzle connected to the inner cavity of the forming keel, the first rollers on adjacent forming keels are connected in series laterally by a flexible shaft perpendicular to the length direction of the forming keel, the air nozzles and the first rollers on the same forming keel are distributed at intervals, and the forming keel is also connected to an arc-changing dragon unit, which includes an arc-changing dragon connecting plate, and at least two positions for installing the first rollers on each forming keel are vacant to form an arc-changing dragon installation position;

[0007] A through hole for the forming keel to pass through is provided on the arc-changing dragon connecting plate, and the arc-changing dragon connecting plate is located at the arc-changing dragon installation position of the forming keel, so that all the air nozzles are unobstructed;

[0008] A second roller is installed on the upper side of the arc dragon connecting plate in the same direction as the first roller, and the bearing parts of the second roller and the first roller are on the same arc surface.

[0009] As a preferred solution, the thickness of the arc-changing dragon connecting plate is less than the distance between the two air nozzles.

[0010] As a preferred solution, the installation position of the variable arc keel is not at the two ends of the formed keel.

[0011] As a preferred solution, the variable arc keel connecting plate is provided with fasteners for fixing the formed keel.

[0012] As a preferred solution, the fasteners are bolts, which pass through threaded holes on the arc-changing keel connecting plate and are pressed against the surface of the formed keel.

[0013] As a preferred solution, there are two arc-changing dragon connecting plates, and the two arc-changing dragon connecting plates are located at two quarter-divided points at the end of the formed keel.

[0014] The beneficial effects of the utility model are:

[0015] Based on the defects of the existing technology, a connection structure of a flexible shaft bending forming keel is provided. Compared with the existing connection structure:

[0016] 1. The variable arc dragon unit is set in the middle position of the formed keel to ensure the deflection while extending the length of the formed keel, realizing an ultra-long wind grid with continuous blowing. The number of formed keels and variable arc dragon units can also be reduced in the ultra-long curved wind grid matrix, making the layout faster.

[0017] 2. The connecting plate of the variable arc dragon unit is moved between two adjacent air nozzles without blocking the air nozzles. The air nozzles can fully cover the formed keel;

[0018] In the layout of super-long curved wind grilles, there are no more curved dragon units between adjacent formed keels, and the wind nozzles can be continuous, thereby ensuring uniform blowing;

[0019] 3. Set a second roller on the curved dragon connecting plate to cooperate with the first roller to ensure that the rollers and the air nozzles are still distributed at equal intervals and do not affect the transfer of the curved glass. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may also be beneficially combined in other embodiments.

[0027] It should be noted that: unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which the present invention belongs. The words "one", "an" or "the" and the like used in the specification and claims of the present utility model patent application do not express quantity restrictions, but rather indicate the presence of at least one; the words "first", "second" and "third" used herein shall not be regarded as restrictions on the order of components, but merely serve to distinguish different components; words such as "include" or "comprise" indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.

[0028] In order to more clearly describe the specific structural composition of the connection structure of the flexible shaft bending forming keel, Figure 1-4 Describe this embodiment:

[0029] like Figure 1 As shown, a connection structure of a flexible shaft bending forming keel is provided. A first roller 2 and an air nozzle 3 communicating with the inner cavity of the forming keel 1 are provided on the upper surface of the forming keel 1. The first rollers 2 on adjacent forming keels 1 are connected in series laterally by a flexible shaft 4 perpendicular to the length direction of the forming keel 1. The air nozzles 3 and the first rollers 2 on the same forming keel 1 are spaced apart. The forming keel 1 is also connected to an arc-changing keel unit, which includes an arc-changing keel connecting plate 5. At least two positions for mounting the first roller 2 on each forming keel 1 are vacant, forming an arc-changing keel mounting position.

[0030] It is worth noting that in addition to the arc-changing dragon connecting plate 5, the arc-changing dragon unit also has a driving mechanism for driving the arc-changing dragon connecting plate 5 to change arc. The arc-changing dragon connecting plates 5 on adjacent formed keels 1 are generally connected by rotating pins. The arc-changing dragon unit adopts existing technology, so it will not be described in detail here.

[0031] See Figure 2 , a through hole 501 is provided on the variable arc dragon connecting plate 5 for the forming keel 1 to pass through, and the variable arc dragon connecting plate 5 is located in the variable arc dragon installation position of the forming keel 1, so that all the air nozzles 3 are unobstructed; after the forming keel 1 passes through the through hole 501, the variable arc dragon connecting plate 5 can be transferred to the middle position of the forming keel 1, reducing the span of the two variable arc dragon connecting plates 5, ensuring the deflection while extending the length of the forming keel 1, changing the current situation that the length of the equipment is limited by the length of the keel, and realizing ultra-long wind grids with continuous blowing. The number of forming keels and variable arc dragon units can also be reduced in the ultra-long curved wind grid matrix, and the layout is faster.

[0032] Specifically, the shape of the through hole 501 is designed according to the cross-sectional shape of the formed keel 1 .

[0033] In the above embodiment, the variable arc dragon installation position no longer needs to be placed at the two ends of the forming keel 1. Generally, two variable arc dragon connecting plates 5 are provided. For example, the two variable arc dragon connecting plates 5 can be located at two quarter points at the end of the forming keel 1. That is, there are three quarter points on the forming keel 1, and the variable arc dragon connecting plates 5 are located at the equal points at both ends.

[0034] When the variable arc dragon connecting plate 5 of the variable arc dragon unit is in the variable arc dragon installation position, it is also between two adjacent air nozzles 3, without blocking the air nozzles 3, and the air nozzles 3 can fully cover the forming keel 1; in the layout of the super-long curved wind grid, there is no longer a variable arc dragon unit between adjacent forming keels 1. Figure 4 In the shown super-long curved wind grid matrix, the wind nozzles 3 can be continuous, thereby ensuring the uniformity of the blowing.

[0035] In the above embodiment, the thickness of the arc-changing dragon connecting plate 5 is smaller than the distance between the two air nozzles 3 to ensure that there is no obstruction.

[0036] The second roller 502 is installed on the upper side of the arc dragon connecting plate 5 in the same direction as the first roller 2. The arc dragon unit is deformed so that the second roller 502 and the first roller 2 are on the same arc surface. Figure 3 As shown, a second roller 502 is provided on the curved dragon connecting plate to replace the roller in the original position and used in conjunction with the first roller 2 to ensure that the rollers and the air nozzles 3 are still distributed at equal intervals without affecting the transfer of the bent glass.

[0037] See Figure 2In order to ensure the stability of the connection between the variable arc dragon connecting plate 5 and the formed keel 1, the variable arc dragon connecting plate 5 is provided with a fastener for fixing the formed keel 1. Specifically, the fastener is a bolt 6, which passes through the threaded hole on the variable arc dragon connecting plate 5 and presses on the surface of the formed keel 1.

[0038] Parts not described in detail in this embodiment are prior art.

[0039] It should be noted that although the present invention has been described through the above embodiments, the present invention may also have other various embodiments. Without departing from the spirit and scope of the present invention, it is obvious that those skilled in the art may make various corresponding changes and modifications to the present invention, and such changes and modifications shall fall within the scope of protection of the appended claims and their equivalents.
