Description

Technical Field

[0001] This utility model relates to the field of glass tempering equipment technology, and in particular to a continuously curved tempered air grating outlet structure. Background Technology

[0002] In the prior art, a curved air grid is installed in the frame. The curved air grid includes an upper curved air grid assembly and a lower curved air grid assembly. When the curved air grid is started, the front ends of the upper and lower curved air grid assemblies are lifted by the upper and lower lifting assemblies respectively, causing the front ends of the upper and lower curved air grid assemblies to bend and tilt upwards. At the same time, multiple conveying rollers located between the upper and lower curved air grid assemblies are simultaneously bent to a preset curvature. After the tempered glass is heated to the set temperature in the heating furnace, it is sequentially discharged from the furnace and conveyed by multiple conveying rollers to the curved upper and lower curved air grid assemblies for shaping. Then, it is quenched and shaped by the cooling air output from the upper and lower curved air grid assemblies and discharged from the front end of the curved air grid. In this way, continuous production of glass tempering can be realized.

[0003] Both the upper-curved air grid assembly and the lower-curved air grid assembly are composed of multiple air grid plates. The side of the air grid plate facing the conveyor roller has multiple air outlet holes. The multiple air outlet holes are divided into multiple rows and arranged at intervals along the direction perpendicular to the conveyor roller to form air outlets.

[0004] To improve the cooling effect of the cooling air output from the air grating, the side of the air outlet facing the conveyor roller needs to extend between two adjacent conveyor rollers and be positioned close to the conveying surface of the conveyor rollers. However, in existing technology, there is no gap between adjacent air outlet holes on the air outlet, and the gap between the side of the air outlet and the outer circumference of the nearby conveyor roller is small. If glass breaks during operation, broken glass will accumulate in the gap between the side of the air outlet and the outer circumference of the nearby conveyor roller. This causes the heat-resistant rope wrapped around the outer circumference of the conveyor roller to continuously rub against the broken glass and break. The broken heat-resistant rope comes into contact with the glass during the tempering process, affecting the surface flatness of the output tempered glass and reducing product quality. Utility Model Content

[0008] Furthermore, the air outlet assembly also includes a fixed base extending along the length direction of the air collection duct; The mounting base is provided with multiple mounting through holes, which penetrate the mounting base. One end of the air outlet pipe passes through the mounting through hole, then passes through the side of the air collecting pipe facing the conveying roller, and connects with the inner cavity of the air collecting pipe. The outer side of the fixed base is away from the bottom surface of the conveying roller.

[0009] Preferably, the outer peripheral surface of the fixing seat is a conical surface that is smaller at the top and larger at the bottom.

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1-3 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0017] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] A continuously curved steel wind grille air outlet structure includes multiple air outlet components 6; The air outlet assembly 6 includes an air collection duct 61 and multiple air outlet ducts 63; Located below the conveyor roller 2, the air collecting pipe 61 is installed on the lower lifting assembly 4. The air collecting pipe 61 is connected to the outside to input cooling gas. The air collecting pipe 61 extends along the length direction parallel to the conveyor roller 2. One end of the air outlet pipe 63 passes through the side of the air collecting pipe 61 facing the conveying roller 2 and is connected to the inner cavity of the air collecting pipe 61; the other end of the air outlet pipe 63 extends into the space between two adjacent conveying rollers 2 and is close to the conveying surface of the conveying roller 2 used to transport the tempered glass 10; a plurality of the air outlet pipes 63 are arranged at intervals in the air collecting pipe 61. The gaps between two adjacent air outlet pipes 63, the gap between the side of the air collecting pipe 61 and the adjacent conveying roller 2, and the gap between two adjacent air collecting pipes 61 are connected to form a discharge channel for discharging broken glass downwards.

[0020] like Figure 1 and Figure 4 As shown in the figure, icon 5 refers to the prior art wind grating 5, and icon 6 refers to the air outlet component 6 of this utility model.

[0021] In the prior art, a curved air grid is installed in the frame 1. The curved air grid includes an upper curved air grid assembly and a lower curved air grid assembly. When the curved air grid is started, the front ends of the upper curved air grid assembly and the lower curved air grid assembly are lifted by the upper lifting assembly 3 and the lower lifting assembly 4 respectively, so that the front ends of the upper curved air grid assembly and the lower curved air grid assembly bend and tilt upwards. At the same time, multiple conveying rollers 2 located between the upper curved air grid assembly and the lower curved air grid assembly bend to a preset curvature. After the tempered glass 10 is heated to the set temperature in the heating furnace, it is taken out of the furnace in sequence and conveyed by multiple conveying rollers 2 to the curved upper curved air grid assembly and the lower curved air grid assembly for forming. Then, it is quenched and shaped by the cooling air output from the upper curved air grid assembly and the lower curved air grid assembly, and then discharged from the front end of the curved air grid. In this way, continuous production of glass tempering can be realized.

[0022] Both the upper-bend air grid assembly and the lower-bend air grid assembly are composed of multiple air grid plates 5. The side of the air grid plate 5 facing the conveyor roller 2 is provided with multiple air outlet holes. The multiple air outlet holes are divided into multiple rows and arranged at intervals along the direction perpendicular to the conveyor roller 2 to form air outlets.

[0023] To improve the cooling effect of the cooling air output by the air grating 5, the side of the air outlet facing the conveyor roller 2 needs to extend between two adjacent conveyor rollers 2 and be positioned close to the conveying surface of the conveyor roller 2. However, due to the lack of gap between adjacent air outlet holes on the existing air outlet and the small gap between the side of the air outlet and the outer circumference of the nearby conveyor roller 2, if glass breaks during operation, broken glass will accumulate in the gap between the side of the air outlet and the outer circumference of the nearby conveyor roller 2. This causes the heat-resistant rope wrapped around the outer circumference of the conveyor roller 2 to continuously rub against the broken glass and break. The broken heat-resistant rope coming into contact with the glass during the tempering process will also affect the surface flatness of the output tempered glass, reducing product quality.

[0024] In the continuously bent tempered air grate air outlet structure of this utility model, the gap between two adjacent air outlet pipes 63, the gap between the side of the air collecting pipe 61 and the nearby conveying roller 2, and the gap between two adjacent air collecting pipes 61 are connected to form an exhaust channel, which can effectively discharge broken glass downwards.

[0025] Furthermore, the air outlet assembly 6 also includes a plurality of mounting bases 62; Each of the multiple mounting bases 62 corresponds to one of the multiple air outlet pipes 63; each mounting base 62 is provided with a mounting through hole 621, which penetrates the mounting base 62. The fixing seat 62 is fitted onto the outer peripheral surface of the corresponding air outlet pipe 63. The bottom surface of the fixing seat 62 is fixed to the side of the air collecting pipe 61 facing the conveying roller 2. The inner wall of the mounting through hole 621 is tightly attached to the outer peripheral surface of the air outlet pipe 63. A gap is left between two adjacent fixing seats 62, and they are connected to the discharge channel.

[0026] like Figure 1 and Figure 2 As shown, the installation stability of the air outlet duct 63 can be improved by using the fixing seat 62; the gap between two adjacent fixing seats 62 can prevent the discharge of falling broken glass from being obstructed.

[0027] Furthermore, the air outlet assembly 6 also includes a fixed base 62 extending along the length direction of the air collection pipe 61; The mounting base 62 is provided with a plurality of mounting through holes 621, which penetrate the mounting base 62. One end of the air outlet pipe 63 passes through the mounting through hole 621, then through the side of the air collecting pipe 61 facing the conveying roller, and is connected to the inner cavity of the air collecting pipe 61. The outer side of the fixed seat 62 is away from the bottom surface of the conveying roller 2.

[0028] like Figure 4 As shown, as another implementation, an integrally formed fixing seat 62 extending along the length of the air collection pipe 61 can also be used, and multiple air outlet pipes 63 can be installed through multiple mounting through holes 621 provided in the fixing seat 62, as long as the outer side of the fixing seat 62 is far away from the bottom surface of the conveying roller 2 to keep the discharge channel unobstructed.

[0029] Preferably, the outer peripheral surface of the fixing seat 62 is a conical surface that is smaller at the top and larger at the bottom.

[0030] like Figure 1 and Figure 2 As shown, the outer periphery of the fixing seat 62 is a conical surface that is smaller at the top and larger at the bottom, which is more conducive to improving the smoothness of broken glass discharge.

[0031] Furthermore, located above the conveying roller 2, the air collecting pipe 61 is installed on the continuously bent and steelened upper lifting assembly 3, and the plurality of fixed seats 62 and the plurality of air outlet pipes 63 are respectively installed on the air collecting pipe 61. Along the glass running direction, the plurality of air outlet pipes 63 located above the conveying roller 2 are staggered with the plurality of air outlet pipes 63 located below the conveying roller 2.

[0032] like Figure 1 and Figure 2 As shown, the multiple air outlet pipes 63 located above the conveyor roller 2 and the multiple air outlet pipes 63 located below the conveyor roller 2 are staggered to avoid uneven distribution of cold energy blown onto the two sides of the glass to be tempered.

[0033] Furthermore, the air outlet pipe 63 is also provided with an air outlet cap 631; The air outlet cap 631 is installed at the other end of the air outlet pipe 63 and is close to the conveying surface of the conveying roller 2; The air outlet cap 631 is provided with a plurality of air outlet holes 6311, which penetrate the air outlet cap 63, and the plurality of air outlet holes 6311 are symmetrically distributed with the central axis of the air outlet pipe 63 as the center.

[0034] like Figure 3 As shown, an air outlet cap 631 is provided at the other end of the air outlet pipe 63 near the conveying surface of the conveying roller 2, and multiple air outlet holes 6311 are provided symmetrically in the center, which can improve the uniformity of the distribution of cooling air on the surface of the glass to be tempered 10.

[0035] Furthermore, the side of the air outlet cap 631 facing the conveying roller 2 is a conical surface that protrudes towards the conveying surface and is centrally symmetrical; The air outlet 6311 is inclined, and the angle between the central axis of the air outlet 6311 and the central axis of the air outlet pipe 63 is angle a; the angle a is 20-25°.

[0036] like Figure 3 As shown, the side of the air outlet cap 631 facing the conveying surface is set as a protruding conical surface, and the multiple air outlets 6311 are set at an angle, so that the cooling air discharged from the two air outlets 6311 located in adjacent air outlet pipes 63 and close to each other interferes with each other on the surface of the tempered glass 10, thereby reducing the appearance of wind spots on the surface of the tempered glass.

[0037] Preferably, the diameter of the air outlet pipe 63 does not exceed 1 / 3 of the distance between two adjacent conveying rollers 2; The gap between two adjacent air outlet pipes 63 is not less than 1 / 2 of the distance between two adjacent conveyor rollers 2.

[0038] This ensures the cooling effect of the glass to be tempered 10 while preventing the discharge channel from being too narrow and affecting the smooth discharge of broken glass.

[0039] In summary, such as Figure 1-3 The embodiment of the present invention shown in the figure has a continuously curved tempered air grate outlet structure. The gap between two adjacent air outlet pipes 63, the gap between the side of the air collection pipe 61 and the nearby conveying roller 2, and the gap between two adjacent air collection pipes 61 are connected to form an outlet channel, which can effectively discharge broken glass downwards, prevent the heat-resistant rope sleeve from breaking, and avoid affecting the quality of glass tempering.

[0040] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
