Description

Technical Field

[0001] This utility model belongs to the field of glass production technology, and in particular relates to cooling devices and glass production lines. Background Technology

[0002] Black border patterns are the most common screen-printed pattern for automotive glass, primarily used on adhesively mounted automotive glass. They serve two purposes: firstly, to cover the adhesive for aesthetic purposes; and secondly, to enhance the bond between the glass and the car body frame. During the automotive glass printing process, the ink printed around the glass edges typically requires high-temperature curing (drying temperature usually 150-300℃). In traditional processes, after ink drying, the glass surface temperature often remains between 80℃ and 120℃. Therefore, a glass cooling system is needed to rapidly and significantly reduce the glass surface temperature to a level suitable for manual removal, minimizing the risk of burns to operators and facilitating production.

[0003] However, most existing glass air-cooling devices use U-shaped ducts. The cooling air blown out by the U-shaped ducts has inconsistent air pressure, resulting in uneven cooling of the glass surface. This can easily lead to warping of the printed area edges and the growth of micro-cracks. In addition, the cooling area of ​​the U-shaped duct is small, resulting in low cooling efficiency. Utility Model Content

[0004] The purpose of this application is to provide a cooling device that aims to solve the problem of how to improve the cooling effect and cooling efficiency of the component to be cooled.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a cooling device is provided for cooling a component to be cooled. The cooling device includes a bellows with an inner cavity and a blowing structure communicating with the inner cavity. The blowing structure is used to blow airflow into the inner cavity. The bellows has an air outlet surface facing the component to be cooled. The air outlet surface is provided with a plurality of air holes communicating with the inner cavity. The airflow is blown towards the component to be cooled through the air holes to cool the component. Two bellows are spaced apart, and the component to be cooled is located between the two bellows. The air outlet surface of one bellows corresponds to the air outlet surface of the other bellows.

[0007] In some embodiments, the air vents are evenly arranged on the air outlet surface.

[0008] In some embodiments, the cooling device further includes a conveying structure for conveying the component to be cooled along a preset direction, the blowing structure being disposed on the conveying path of the component to be cooled, and the conveying structure passing between two blowing structures.

[0010] In some embodiments, the cooling device further includes a temperature sensing structure communicatively connected to the blowing structure, the temperature sensing structure being used to detect the temperature in the area between the two air boxes and generate a temperature signal, the blowing structure being used to adjust the flow rate of the airflow according to the temperature signal.

[0011] In some embodiments, the air box is provided with an air inlet that connects the inner cavity with the outside air, and the blowing structure includes a centrifugal fan disposed at the air inlet, the centrifugal fan being used to draw outside gas into the inner cavity.

[0012] In some embodiments, the blowing structure further includes a filter connected to the centrifugal fan, the filter being in communication with the centrifugal fan and used to filter the gas entering the centrifugal fan.

[0013] In some embodiments, the cooling device further includes a packaged cover having a accommodating cavity, the air box being housed in the accommodating cavity, and the packaged cover having an exhaust port communicating with the accommodating cavity, the exhaust port being used to allow the airflow to exit the accommodating cavity.

[0014] In some embodiments, the inner wall of the encapsulation cover is provided with a sound-insulating layer for sound insulation.

[0015] Secondly, a glass production line is provided, which includes the cooling device described above.

[0016] The beneficial effects of this application are as follows: The cooling device provided in this application provides that by setting multiple air holes to blow airflow onto the part to be cooled, the high-pressure airflow in the inner cavity can be dispersed into multiple independent micro-airflow units, forming a uniformly covered laminar air film on the surface of the part to be cooled, thereby achieving uniform cooling, eliminating stress defects, and improving the cooling effect; and by setting two air boxes to blow airflow onto the opposite sides of the part to be cooled at the same time, the cooling of both sides of the part to be cooled is balanced, preventing thermal stress deformation caused by unilateral cooling of the part to be cooled, further improving the cooling effect, and the airflow on both sides simultaneously carries away heat, which can significantly shorten the cooling time and improve the cooling efficiency.

[0029] Please see Figures 1 to 5 This application provides a cooling device for cooling a component 200 to be cooled. The cooling device includes a blower 10 with an inner cavity 11 and a blowing structure 20 communicating with the inner cavity 11. The blowing structure 20 is used to blow airflow into the inner cavity 11. The blower 10 has an air outlet surface 12 facing the component 200 to be cooled. The air outlet surface 12 is provided with a plurality of air holes 121 communicating with the inner cavity 11. The airflow is blown towards the component 200 to be cooled through the air holes 121 to cool the component 200. Two blowers 10 are arranged at intervals. The component 200 to be cooled is located between the two blowers 10. The air outlet surface 12 of one blower 10 corresponds to the air outlet surface 12 of the other blower 10.

[0030] Understandably, the component to be cooled 200 in this embodiment can be glass. When the glass is laid flat between the two air boxes 10, the two surfaces of the glass correspond to the two air outlet surfaces 12 of the two air boxes 10, respectively. Of course, in other possible embodiments, the component to be cooled 200 can also be other structures that need to be cooled. This application does not limit the specific structure of the component to be cooled 200.

[0031] This application uses two bellows 10 simultaneously for air blowing, which enhances the cooling effect. Understandably, taking glass as an example (the part to be cooled 200), since glass has a certain thickness, if only one bellows 10 is used for air blowing, only one surface of the glass can be cooled quickly, resulting in insufficient cooling of the other surface. However, by using two bellows 10 simultaneously, the cooling of both sides of the part to be cooled 200 is more even, preventing thermal stress deformation caused by unilateral cooling and thus improving the cooling effect.

[0032] The cooling device provided in this application embodiment blows airflow onto the part to be cooled 200 through multiple air holes 121, which can disperse the high-pressure airflow in the inner cavity 11 into multiple independent micro-airflow units, forming a uniformly covered laminar air film on the surface of the part to be cooled 200, thereby achieving uniform cooling, eliminating stress defects, and improving the cooling effect. Furthermore, by setting two air boxes 10 to blow airflow onto the opposite sides of the part to be cooled 200 at the same time, the cooling of the part to be cooled 200 on both sides is balanced, preventing thermal stress deformation caused by unilateral cooling of the part to be cooled 200, further improving the cooling effect. Moreover, the airflow on both sides carries away heat at the same time, which can significantly shorten the cooling time and improve the cooling efficiency.

[0033] In some embodiments, such as Figure 1 and Figure 2 As shown, two air-blowing structures 20 are provided, each connected to one of the two air boxes 10, thereby ensuring that the airflow from the two air boxes 10 is consistent and that the cooling of the component 200 is more uniform. Of course, in other possible embodiments, only one air-blowing structure 20 may be provided, connected to two pipes, each connected to one of the two air boxes 10, which can also provide airflow to the two air boxes 10.

[0034] In some embodiments, such as Figure 3 and Figure 4As shown, the air holes 121 are evenly distributed on the air outlet surface 12, forming an equidistant honeycomb-shaped air hole matrix on the air outlet surface 12. This equidistant honeycomb-shaped air hole matrix creates a continuously covering laminar air film on the surface of the part to be cooled 200, effectively reducing the lateral temperature difference on the surface of the part to be cooled 200, ensuring a uniform temperature reduction on the surface of the part to be cooled, and minimizing the range of compressive stress fluctuations on the surface of the cooled part. Furthermore, by setting multiple evenly distributed air holes 121, localized high temperatures on the surface of the part to be cooled 200 can be precisely eliminated, reducing the risk of burns during manual unloading.

[0035] Optionally, in this embodiment, the air outlet surface 12 is planar. A planar air outlet surface 12 makes it easier to create air vents 121, simplifies the manufacturing process, reduces production costs, and makes maintenance more convenient. It is also more suitable for standardized production and can accommodate components 200 of different sizes to be cooled. Furthermore, blowing air through the flat air outlet surface 12 reduces the wind speed difference in the width direction of the component 200 to be cooled, further reducing the lateral temperature difference on the surface of the component 200. Of course, in other possible embodiments, the air outlet surface 12 in this embodiment can also be curved. A curved air outlet surface 12 can match the glass surface, and the curvature of the curved air outlet surface 12 can match the curvature changes of 3D curved glass, such as automotive cover glass, thereby improving applicability.

[0036] In some embodiments, the cooling device further includes a conveying structure 30 for conveying the component 200 to be cooled along a preset direction a. A blowing structure 20 is disposed on the conveying path of the component 200, and the conveying structure 30 passes between two blowing structures 20. The conveying structure 30 can convey the component 200 to be cooled, allowing it to enter the blowing range of the two blowers 10. The two blowers 10 then blow air onto the component 200 for cooling. After cooling is complete, the conveying structure 30 conveys the component 200 to the next station, thereby automatically performing the cooling process and effectively improving the efficiency of the component 200.

[0037] In some embodiments, multiple air boxes 10 are arranged along a preset direction a. The multiple air boxes 10 can be spliced ​​together to form an integral structure, which can increase the blowing range during the conveying of the part to be cooled 200, thereby increasing the cooling time and further improving the cooling effect.

[0038] In some embodiments, the preset direction a of this application embodiment is the horizontal direction, and the two air boxes 10 are located above and below the component to be cooled 200, respectively. The upper air box 10 blows air downward in the vertical direction, and the lower air box 10 blows air upward in the vertical direction.

[0039] In some embodiments, such as Figure 2As shown, the conveying structure 30 includes rotatably arranged conveyor rollers 31. Multiple conveyor rollers 31 are arranged at intervals along a preset direction a. The part to be cooled 200 contacts the roller surface of the conveyor rollers 31. An airflow channel 33 is formed between two adjacent conveyor rollers 31 for the airflow blown out by the air outlet surface 12 to pass through. It can be understood that the conveyor rollers 31 rotate in the same direction, thereby driving the part to be cooled 200 forward. The airflow passes through the airflow channel 33 formed between two adjacent conveyor rollers 31 and blows onto the part to be cooled 200, so that the conveying structure 30 does not obstruct the airflow.

[0040] By setting multiple conveyor rollers 31 arranged at intervals, continuous support is provided for the part to be cooled 200, avoiding wrinkles or deformation caused by gravity sagging. In addition, the surface of the part to be cooled 200 is smooth and has a low coefficient of rolling friction, avoiding scratches or stretching deformation on the surface of the part to be cooled 200.

[0041] In some embodiments, the bearing surface of the conveying structure 30 is provided with a microstructure texture. Specifically, the microstructure texture is honeycomb or wavy in shape, which can reduce the contact area between the part to be cooled 200 and the bearing surface and reduce the risk of adhesion of the part to be cooled 200 due to thermal expansion.

[0042] In another possible implementation, the conveying structure 30 further includes a conveyor belt wound around the conveyor roller 31. The conveyor roller 31 rolls, causing the conveyor belt to move forward, thereby conveying the part 200 to be cooled forward. Optionally, the conveyor belt is a perforated mesh belt that conveys forward, with mesh openings for airflow to pass through, thus ensuring airflow. Optionally, the conveyor belt is a high-temperature resistant Teflon mesh belt, which can improve the resistance to high-temperature parts 200 and extend their service life.

[0043] In some embodiments, such as Figure 5 As shown, the cooling device also includes a temperature detection structure 40 that is communicatively connected to the air blowing structure 20. The temperature detection structure 40 is used to detect the temperature of the area between the two air boxes 10 and generate a temperature signal. The air blowing structure 20 is used to adjust the airflow speed according to the temperature signal.

[0044] The temperature sensing structure 40 monitors the temperature in real time, while the air blowing structure 20 adjusts the airflow speed. This allows for more precise control of the cooling process, achieving accurate temperature control, avoiding overheating or overcooling, and saving energy. For example, the cooperation between the temperature sensing structure 40 and the air blowing structure 20 can prevent micro-cracks from forming in the part to be cooled 200 due to sudden cooling, or ensure that the surface temperature of the part to be cooled 200 remains stable within a preset range during unloading, eliminating the risk of manual operation and preventing burns. Understandably, the cooperation between the temperature sensing structure 40 and the air blowing structure 20 can also adapt to parts to be cooled 200 with different cooling temperature requirements, allowing for flexible adjustments based on these requirements, thereby improving the applicability and flexibility of the cooling device.

[0045] In some embodiments, the air box 10 is provided with an air inlet 13 connecting the inner cavity 11 to the outside air, and the blowing structure 20 includes a centrifugal fan 21 disposed at the air inlet 13. The centrifugal fan 21 is used to draw outside air into the inner cavity 11. Understandably, the centrifugal fan 21 has an impeller, which is driven by a motor to rotate at high speed, creating a negative pressure in the central area. Therefore, outside air can be drawn into the inner cavity 11 under atmospheric pressure through the centrifugal fan 21. The centrifugal fan 21 can provide stable air pressure, thereby enhancing the stability of the airflow entering the inner cavity 11, and further stabilizing the airflow blowing towards the component 200 to be cooled, thereby further enhancing the cooling effect of the component 200 to be cooled.

[0046] Optionally, the centrifugal fan 21 in this embodiment is a multi-blade fan. Multi-blade fans enhance the acceleration and compression efficiency of airflow through multi-blade design (usually with a large number of blades, such as 42, 48 or even more), thereby generating higher pressure. In addition, multi-blade fans are small in size and occupy less space, making them suitable for places with limited installation space.

[0047] In some embodiments, the blowing structure 20 further includes a filter 22 connected to the centrifugal fan 21. The filter 22 is in communication with the centrifugal fan 21 and is used to filter the gas entering the centrifugal fan 21. By setting the filter 22, impurities in the gas entering the air box 10 can be removed, ensuring that the surface of the part to be cooled 200 is relatively clean, meeting the production process requirements, and providing a clean part to be cooled 200 for the next production process.

[0048] In some embodiments, the air inlet 13 is disposed on the surface adjacent to the air outlet 12, and the air inlet direction of the air inlet 13 is parallel to the air outlet 12. Specifically, the air outlet 12 is disposed at the bottom of the air box 10, and the air inlet 13 is disposed on the side of the air box 10. Therefore, the airflow entering from the air inlet 13 can flow from one side of the air box 10 to the middle of the air box 10 and continue to flow to the other side of the air box 10, so that the flow area of ​​the airflow covers the air outlet 12, ensuring that all the air holes 121 of the air outlet 12 have airflow blowing out, and ensuring that the entire surface of the part to be cooled 200 can be cooled.

[0049] In some embodiments, the air inlets 13 of the two air boxes 10 are located on the same side, which facilitates the maintenance of the fan. Of course, in other possible embodiments, the air inlets 13 of the two air boxes 10 can be located on opposite sides of the cooling device, and the location of the air inlets 13 can be selected according to actual needs, as long as it can meet the space design requirements of the production site.

[0050] In some embodiments, such as Figure 5As shown, the cooling device also includes an encapsulation cover 50 with a receiving cavity 51. The air box 10 is housed in the receiving cavity 51. The encapsulation cover 50 has an exhaust port 52 communicating with the receiving cavity 51, which is used to allow airflow to exit the receiving cavity 51. By providing the encapsulation cover 50, the air box 10 and the part to be cooled 200 can be protected, preventing dust or moisture from contaminating the air box 10 and the part to be cooled 200. Furthermore, by providing the exhaust port 52 to discharge airflow from the receiving cavity 51, the exhaust port 52 can quickly discharge the hot airflow rebounding from the surface of the part to be cooled 200, avoiding secondary heating caused by the retention of hot air, thereby improving the actual cooling efficiency of the part to be cooled 200.

[0051] Specifically, the exhaust port 52 can be connected to the exhaust gas treatment pipe, and the gas discharged from the containment chamber 51 enters the exhaust gas treatment pipe, is treated, and then discharged outdoors.

[0052] In some embodiments, a sound-insulating layer 60 for sound insulation is affixed to the inner wall of the enclosure 50, thereby providing sound insulation and improving the working environment. Optionally, the sound-insulating layer 60 is sound-insulating cotton, which can be bonded to the inner wall of the enclosure 50 by adhesive. The sound-insulating layer 60 can also be affixed to the peripheral and top walls of the enclosure 50, thereby further enhancing the sound insulation effect.

[0053] This utility model also proposes a glass production line, which includes a cooling device. The specific structure of the cooling device is as described in the above embodiments. Since this glass production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0054] In summary, the cooling device provided in this application embodiment, by setting multiple air holes 121 to blow airflow onto the part to be cooled 200, can disperse the high-pressure airflow in the inner cavity 11 into multiple independent micro-airflow units, forming a uniformly covered laminar air film on the surface of the part to be cooled 200, achieving uniform cooling, eliminating stress defects, and improving the cooling effect; and by setting two air boxes 10 to blow airflow onto the opposite sides of the part to be cooled 200 at the same time, the cooling of the part to be cooled 200 on both sides is balanced, preventing thermal stress deformation caused by unilateral cooling of the part to be cooled 200, further improving the cooling effect, and the airflow on both sides simultaneously carries away heat, which can significantly shorten the cooling time and improve the cooling efficiency.
