Description

Technical Field

[0001] The present invention relates to the technical field of high-performance borosilicate glass production, and in particular to a kiln device for producing high-performance borosilicate glass. Background Art

[0002] Borosilicate glass is a special glass with silicon dioxide and boron oxide as its main components. It is widely used due to its excellent physical and chemical properties. During preparation: its main raw materials are high-purity silicon dioxide and boron trioxide, and auxiliary materials such as aluminum oxide, sodium oxide and potassium oxide need to be added. The raw materials are passed into a kiln and melted at high temperature to form glass liquid. The molten glass liquid is pressed and cut, and then annealed and cooled to form borosilicate glass. The formed flat glass is transported to the cooling assembly through a conveying assembly for cooling. Cooling generally uses cold air. Because the temperature of the upper surface of the flat glass drops faster than the lower surface, in order to avoid cracks in the glass due to uneven cooling, the cooling time needs to be extended, resulting in low cooling efficiency. The existing technology uses double-sided cooling, that is, cooling by blowing air to the upper and lower surfaces of the flat glass at the same time. However, the part of the glass that contacts the conveying assembly is difficult to be directly contacted by the cold air, resulting in insufficient temperature drop on the lower surface.

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-10 The embodiment of the present invention provides a kiln device for producing high-performance borosilicate glass, comprising:

[0033] A frame 1, on which a transmission component 2 is provided;

[0034] The supporting assembly 5 is provided on the conveying assembly 2 and is used to support the flat glass. The supporting assembly 5 includes a base 51, a lifting seat 52, an embedded block 53, an air inlet 54, a second air outlet 56, an elastic member 58, and a closing member 59. The base 51 is fixed on the conveying assembly 2, the lifting seat 52 is slidably connected in the base 51, the elastic member 58 is provided between the lifting seat 52 and the base 51, the embedded block 53 is embedded in the lifting seat 52, the air inlet 54 is provided at both ends of the embedded block 53, and the second air outlet 56 is provided at the upper part of the embedded block 53;

[0035] The cooling assembly 4 includes a housing 41, an air source 42, a hydraulic cylinder 43, a side plate 47, and an air guide hole 471. A first air port 411 is provided inside the housing 41. The housing 41, the first air port 411, and the air source 42 form a first cooling channel, through which the upper surface of the flat glass is cooled. The side plate 47 is mounted on the housing 41, and the air guide hole 471 is provided in the side plate 47.

[0036] The hydraulic cylinder 43 is used to drive the shell 41 to move in the vertical direction. During the downward movement of the shell 41, the lifting seat 52 moves downward synchronously, so that the closing member 59 is passively expanded. A second cooling channel is formed between the air source 42, the air guide hole 471, the air inlet 54, and the second air outlet 56, and the lower surface of the flat glass is cooled through the second cooling channel.

[0037] In the embodiment of the present invention, the frame 1 is fixed to the bottom surface and is arranged along the discharge direction of the kiln. After being cut, the discharged glass substrate is transported by the industrial robot to the conveyor assembly 2. Since the conveyor assembly 2 is covered by the supporting assembly 5, the glass plate placed on the supporting assembly 5 will also move step by step when the conveyor assembly 2 moves, and the purpose of moving the glass plate to the cooling assembly 4 is achieved through the conveyor assembly 2.

[0038] The elastic member 58 exerts an upward force on the lifting seat 52, causing the bottom surface of the lifting seat 52 to separate from the base 51. When the glass sheet is placed on the lifting seat 52, the elastic member 58 is only slightly compressed. As the conveying assembly 2 moves, the glass sheet is conveyed to the bottom of the cooling assembly 4 and then stops. At this time, the hydraulic cylinder 43 drives the housing 41 to move downward, and the housing 41 will cover the top of the glass sheet. After the air source 42 is turned on, it continuously draws air into the housing 41, and the air pressure in the housing 41 increases. A large amount of air is discharged through the first air outlet 411, and the discharged air contacts the upper surface of the glass sheet, thereby quickly reducing the temperature of the upper surface of the glass sheet.

[0039] See attached Figure 4 and attached Figure 5 During the downward movement of the shell 41, the side panels 47 fixed on both sides thereof will fit against the end surfaces of the embedded block 53, and the lower portion of the air guide hole 471 will be connected to the air inlet 54 located on the embedded block 53, and the upper portion of the air guide hole 471 will be connected to the inner cavity of the shell 41. Therefore, the air in the shell 41 will be transported to the air inlet 54 through the air guide hole 471, and the air in the air inlet 54 will be discharged through the second air outlet 56. The air discharged through the second air outlet 56 will cool the lower surface of the glass plate, thereby helping to cool the position where the glass plate is supported and helping to reduce the temperature difference between the upper and lower surfaces of the glass plate.

[0040] During the downward movement of the shell 41, the lifting seat 52 will also be squeezed, and the lifting seat 52 will overcome the elastic force of the elastic member 58 to move downward. During the downward movement of the lifting seat 52, the closing member 59 will be expanded, so that the gap between the two adjacent cooling components 4 will be blocked by the closing member 59. This arrangement creates a closed surface on the lower surface of the glass plate, and the air discharged through the second air outlet 56 must exert an upward force on the glass plate in order to be discharged. In this way, the glass plate will move upward and separate from the lifting seat 52, thereby forming an air flow channel between the supporting component 5 and the glass plate, and the air will be discharged outward from the channel, which greatly improves the cooling efficiency of the lower surface of the glass plate. After the lower surface of the glass plate is separated from the supporting component 5, the water stains and other attachments remaining on the glass plate will be separated from the glass plate under the action of the high-speed airflow, which is conducive to later stacking.

[0041] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 The transmission assembly 2 includes a transmission shaft 21, a gear 22, a chain 23 and a drive unit 3. The transmission shaft 21 is fixedly mounted on the frame 1, the gear 22 is fixedly mounted on the transmission shaft 21, the gears 22 are connected by a chain 23, and the drive unit 3 and the transmission shaft 21 are connected by a transmission.

[0042] The driving unit 3 is used to drive the transmission shaft 21 to rotate. When the transmission shaft 21 rotates, it can drive the gear 22 to rotate. When the gear 22 rotates, it can drive the chain 23 to rotate. The base 51 is fixed on the chain 23. Therefore, when the chain 23 moves, it can synchronously drive the supporting assembly 5 to move, and the glass plate on the supporting assembly 5 will also move synchronously.

[0043] In the embodiments of the present invention, please refer to Figure 9 The supporting assembly 5 further includes an anti-slip pin 57 , one end of which slides through the base 51 and is then fixed to the bottom surface of the lifting seat 52 .

[0044] The anti-slip pin 57 prevents the lifting seat 52 from being separated from the base 51 , so that the lifting seat 52 can only slide along the base 51 .

[0045] In the embodiments of the present invention, please refer to Figure 9 The embedding block 53 and the lifting seat 52 are detachably connected. The detachable configuration of the embedding block 53 can significantly reduce the manufacturing cost. By performing wire cutting on the lifting seat 52 and the embedding block 53, a close fit between the two can be achieved to avoid air leakage.

[0046] In the embodiments of the present invention, please refer to Figure 4-6 The cooling assembly 4 further includes a pressing plate 45 and a limiting block 46 . The pressing plate 45 is fixedly mounted on the side plate 47 , and the limiting block 46 is fixedly mounted on the pressing plate 45 .

[0047] The pressure plate 45 is installed on the side plate 47. When the side plate 47 moves downward, the pressure plate 45 will be pressed on the supporting assembly 5. The pressure plate 45 presses the lifting seat 52, so that the lifting seat 52 overcomes the elastic force of the elastic member 58 and moves downward. The limit block 46 can limit the four corners of the glass plate. When the glass plate is blown upward by the airflow, its floating height is limited by the limit block 46 to avoid the height being too high and causing the flow rate of the air flow channel to decrease.

[0048] In the embodiments of the present invention, please refer to Figure 1, further comprising a mounting frame 44 , wherein the mounting frame 44 is fixedly mounted on both sides of the frame 1 , the hydraulic cylinder 43 is fixedly mounted on the mounting frame 44 , and the output end of the hydraulic cylinder 43 is fixedly mounted on the housing 41 .

[0049] The mounting brackets 44 are fixedly mounted on both sides of the frame 1 , and the height of the housing 41 can be adjusted by extending and retracting the hydraulic cylinder 43 .

[0050] See also Figure 7 As shown, a blocking block 48 is provided on the shell 41 to prevent the glass plate from being displaced to both sides under the action of high-speed airflow, and the lower part of the blocking block 48 is longer, which can also play a blocking role. When the shell 41 has not completely fallen, the blocking block 48 is adjusted to the moving path of the glass plate through the appropriate height of the shell 41 to prevent the glass plate from moving forward.

[0051] In the embodiments of the present invention, please refer to Figure 4 , the flux of the first air outlet 411 is not greater than the flux of the second air outlet 56.

[0052] The number of the first air outlets 411 is small, which avoids excessive air volume causing the upper surface to cool too quickly, and can also reduce the pressure of the air discharged from the first air outlets 411 on the glass plate, so that the glass plate can move up smoothly.

[0053] In the embodiments of the present invention, please refer to Figure 4 and Figure 10 A first arc chamfer 451 is provided at one end of the pressing plate 45 , and a second arc chamfer 452 is provided at the lower portion of the pressing plate 45 close to the flat glass.

[0054] The glass sheet may be slightly deflected during transportation. The second arc chamfer 452 of the pressure plate 45 is set to center the glass sheet when the pressure plate 45 is pressed down, while the first arc chamfer 451 can reduce the downward pressure on the supporting component 5 on the outside.

[0055] In the embodiments of the present invention, please refer to Figure 5 The upper portion of the air guide hole 471 is connected to the air source 42 , and the lower portion of the air guide hole 471 is adapted to the air inlet 54 .

[0056] The air in the housing 41 enters the air inlet 54 through the air guide holes 471 , and the insufficient air can be discharged from the second air outlet 56 to cool the lower surface of the glass plate.

[0057] Preferably, the air source 42 delivers filtered air into the housing 41. The air source 42 may be equipped with a high-pressure centrifugal fan to maintain sufficient air pressure within the housing 41. It should be noted that excessively low air pressure will cause all air to be discharged from the first air outlet 411, so high air pressure is required. Because the air discharged from the first air outlet 411 suddenly enters a larger space and dissipates more quickly, the air discharged from the first air outlet 411 exerts less downward pressure on the glass sheet. However, the airflow space of the second air outlet 56 is narrow, and the airflow will inevitably push the glass sheet upward.

[0058] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
