Description

Technical Field

[0001] This utility model relates to a rapid cooling device, and more particularly to a rapid cooling device for tempered glass forming. Background Technology

[0002] Tempered glass is made by heating ordinary flat glass to near its softening point and then rapidly cooling it, which forms a compressive stress layer on its surface and a tensile stress layer inside, thus greatly improving its mechanical strength and impact resistance. This process not only enhances the safety of the glass but also gives it better thermal stability and resistance to thermal shock.

[0003] Existing tempered glass cooling devices typically involve rapidly feeding a heated glass plate into a cooling zone, which is often filled with a cooling medium. Uniform cooling of the glass is achieved by controlling the temperature, flow rate, and distribution of the cooling medium. In practice, the cooling medium (such as cold air) circulates and removes heat from the glass surface directly or through heat exchange until the glass reaches the required cooling temperature and stress state. During cooling, temperature differences may exist between the upper and lower surfaces; for example, the side coated with an enamel layer or metal film layer dissipates heat more slowly than other areas. Conventional cooling devices often cannot precisely adjust the position of the medium ejector, as well as the medium temperature and flow rate, based on the glass surface temperature. This can lead to uneven cooling rates in different parts of the glass, potentially causing uneven internal stress and affecting product quality. Utility Model Content

[0004] In order to overcome the shortcomings mentioned in the background art, the purpose of this utility model is to provide a rapid cooling device for tempered glass forming that precisely controls the cooling process according to the glass surface temperature.

[0005] The technical solution of this utility model is: a rapid cooling device for tempered glass forming, including a base, a control console, a top cover, a transmission component, a cooling component, air vents, and infrared detectors. The base has a material transmission channel, and there are material transmission notches on both the left and right sides of the base. The control console is located at the front of the base, and the top cover is located on the upper part of the base. A transmission component is horizontally arranged on the base, through which the glass is transmitted from left to right. Cooling components are horizontally arranged in the lower part of both the top cover and the base, with two cooling components arranged opposite each other. The cooling components and the transmission component are arranged in the same direction. The glass transmitted on the transmission component passes through the area between the two cooling components. Each cooling component has several air vents, and a control module is located inside the cooling component. The control module precisely controls the air volume and the air temperature of each air vent. Each cooling component has several infrared detectors, and the detection probes of the infrared detectors are all facing the side of the transmission component.

[0006] Optionally, it also includes a circulation component and a guide block. The circulation component is symmetrically arranged on the front and rear sides inside the base. The circulation component has several air holes on the inward side. The guide block is symmetrically arranged on the upper and lower sides of the inward side of the circulation component. The guide block, the circulation component and the cooling component together form an airflow circulation channel. When the circulation component is working, the airflow enters the circulation component from the upper air hole of the rear circulation component and exits from the lower air hole. The circulation component on the front side draws in the airflow through the lower air hole and exits through the upper air hole.

[0007] Optionally, it also includes a partition, with a partition provided between the left side of the base and the top cover, which divides the material transfer channel in the base into two spaces, and the partition has a notch to allow the glass on the transfer component to pass through.

[0008] Optionally, it also includes an insulated box and a temperature control device. The insulated box is located on the right side of the base. The right side of the transmission component extends out from the right side of the base and also through the right side of the insulated box. There are notches on both the left and right sides of the insulated box. The internal space of the insulated box is connected to the internal transmission channel of the base. When the material on the transmission component is transferred out from the base, it will enter the insulated box. The temperature control device is located on the upper part of the insulated box. The temperature control device is connected to the internal space of the insulated box through a pipe.

[0009] Optionally, it also includes a detection module and a vision inspection instrument. The detection module is located at the notch on the right side of the insulation box, and the vision inspection instrument is installed on the detection module. The detection probe of the vision inspection instrument faces the side of the transmission component.

[0010] The beneficial effects are as follows: This utility model continuously transports glass through a transmission component, and sets a cooling component and multiple temperature detectors connected to the cooling component along the glass transmission path. During the cooling process, the multiple temperature detectors can monitor the temperature changes at different locations on the glass surface in real time. Furthermore, by setting several independently controlled air vents on the cooling component, the wind speed and air volume of each vent are automatically adjusted to ensure a consistent cooling rate in each area, thus avoiding the uneven temperature problem commonly found in traditional cooling methods.

[0011] This invention circulates the escaping airflow from the cooling component by setting up a circulation component and a guide block. The circulation component can effectively collect and redistribute the airflow near the air vents, and then circulate it into the transmission channel of the base. This reduces the mutual influence of the airflow that moves around when multiple air vents of the cooling component are working, and guides the escaping and moving airflow to circulate in a certain direction. This does not affect the normal operation of the cooling component, and ensures the stability and reliability of the entire cooling process.

[0012] This invention uses a partition to separate a pre-cooling zone within the material transfer channel. The glass first enters this pre-cooling zone for initial cooling. The pre-cooling zone effectively reduces the surface temperature of the glass, preparing it for subsequent cooling steps. After leaving the pre-cooling zone, the glass enters an insulated chamber equipped with a temperature control device. This device regulates the temperature inside the chamber, creating a temperature transition zone. This prevents the cooled glass from directly contacting the outside environment and causing a large temperature difference, thus preventing stress changes and potential cracks caused by temperature variations.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that any use of terms such as "up," "down," "left," "right," "front," "back," "inner," and "outer" in this document is based solely on the accompanying drawings and is not intended to specifically limit the scope of this utility model.

[0020] Example 1

[0021] A rapid cooling device for tempered glass forming, such as Figure 1-5As shown, the system includes a base 1, a control console 2, a top cover 3, a transmission component 4, a cooling component 5, an air vent 51, and an infrared detector 52. The base 1 has a material transfer channel, and material transfer notches are provided on both the left and right sides of the base 1 to facilitate the entry and exit of glass. This design ensures that the glass enters and leaves the cooling device smoothly and without obstruction, avoiding glass damage or positional displacement caused by difficulties in entry and exit. The control console 2 is located at the front of the base 1 for operating and monitoring the entire cooling process. The control console 2 is connected to each key component via internal communication lines, receiving and sending commands in real time to ensure all equipment works collaboratively, improving the system's reliability and accuracy.

[0022] A top cover 3 is fixedly installed on the upper part of the base 1. The top cover 3 forms a closed cooling environment on the base 1 to ensure stable internal airflow. A transmission component 4 is horizontally installed on the base 1. The glass is slowly and uniformly transported from left to right through the transmission component 4. The transmission component 4 is driven by a high-precision motor to ensure that the speed of the glass is constant throughout the transmission process and to avoid uneven stress caused by speed fluctuations.

[0023] The top cover 3 and the lower part of the base 1 are both horizontally provided with cooling components 5. The two cooling components 5 are arranged opposite each other and their arrangement direction is consistent with that of the transmission component 4. The glass being transported on the transmission component 4 will pass through the area between the two cooling components 5, so that the glass surface can receive cooling airflow from both the top and bottom. This symmetrical arrangement not only improves the cooling efficiency, but also ensures the cooling consistency of the glass in all directions, reduces the temperature gradient, and reduces the stress change of the glass caused by temperature difference.

[0024] The cooling component 5 is equipped with a control module. Each cooling component 5 has several air vents 51, and each air vent 51 is independently controlled by the control module. The control module precisely controls the air volume and airflow temperature of each air vent 51. This independent control design allows the cooling airflow to be dynamically adjusted according to the actual needs of different parts of the glass, avoiding the uneven temperature problem commonly found in traditional cooling methods. For example, when the glass temperature in some areas is high, the corresponding air vent 51 will increase the air volume and decrease the airflow temperature, and vice versa, it will decrease the air volume and increase the airflow temperature, ensuring that the cooling rate of the entire glass surface is consistent.

[0025] In addition, such as Figure 3As shown, the cooling component 5 is also equipped with several infrared detectors 52. The detection probes of the infrared detectors 52 are all facing the transmission component 4. These infrared detectors 52 can monitor the temperature changes at different locations on the glass surface in real time and feed the data back to the control module. The control module automatically adjusts the airflow speed and volume of each air outlet 51 based on this temperature data to ensure a consistent cooling rate in each area. This not only improves cooling efficiency but also significantly enhances the quality of the glass, reducing cracks and deformations caused by uneven stress. The real-time feedback mechanism between the infrared detectors 52 and the control system makes the entire cooling process more intelligent and efficient, further optimizing the glass cooling effect.

[0026] Example 2

[0027] Based on Example 1, such as Figure 2 , Figure 4 and Figure 5 As shown, it also includes a circulation component 6 and a guide block 61. The circulation component 6 is symmetrically arranged on the front and rear sides inside the base 1. The circulation component 6 has several air holes on the inward side. These air holes are evenly distributed to ensure that the airflow can enter and exit evenly. The guide blocks 61 are symmetrically arranged on the inward side of the circulation component 6. The guide blocks 61, the circulation component 6 and the cooling component 5 together form an airflow circulation channel. This design allows the escaping airflow blown out from the cooling component 5 to be effectively collected and redistributed, ensuring the orderly flow of airflow and reducing the mutual influence of the airflow when multiple air vents of the cooling component are working.

[0028] Specifically, when the circulation component 6 is working, airflow enters the circulation component 6 from the upper air vent on the rear side and exits from the lower air vent. The circulation component 6 on the front side draws in airflow through the lower air vent and exits through the upper air vent. This symmetrical arrangement and airflow path design makes the entire airflow circulation system more efficient and stable. After a series of guidance and adjustments inside the circulation component 6, the airflow re-enters the transmission channel of the base 1, thereby realizing the reuse and optimization of cooling airflow. In addition, the role of the guide block 61 is indispensable. The guide block 61 is not only fixed inside the circulation component 6, but also closely cooperates with the cooling component 5 to form a complete airflow guiding structure. The presence of the guide block 61 ensures that the airflow will not generate turbulence or eddies during circulation, effectively guiding the escaping and turbulent airflow to circulate in a certain direction, avoiding disorderly flow of airflow in the cooling area, further improving the stability and efficiency of airflow, and ensuring that the normal operation of the cooling component 5 is not disturbed by turbulence.

[0029] like Figure 1 , Figure 2 and Figure 4As shown, it also includes a partition 7. A partition 7 is provided between the left side of the base 1 and the top cover 3. The partition 7 divides the material transfer channel in the base 1 into two independent spaces. The partition 7 has a notch to allow the glass on the transfer component 4 to pass through smoothly, ensuring that the glass is not obstructed during the transfer process. The main function of the partition 7 is to divide the material transfer channel in the base 1 into two different functional areas: the left side is the pre-cooling space and the right side is the cooling space. This design allows the glass to be pre-cooled in a relatively low-temperature environment before entering the main cooling area, thereby gradually reducing the temperature and avoiding the impact of a sudden temperature drop on the glass structure. In this space, the glass gradually adapts to the lower temperature, reducing the stress caused by rapid temperature changes. The pre-cooling process helps to improve the quality of the glass and reduce the generation of cracks and other defects.

[0030] like Figure 1 and Figure 2 As shown, it also includes an insulated box 8 and a temperature control device 81. The insulated box 8 is located on the right side of the base 1. The right side of the transmission component 4 extends out from the right side of the base 1 and also extends out from the right side of the insulated box 8. There are notches on both the left and right sides of the insulated box 8 to ensure that the material on the transmission component 4 can pass through smoothly. The internal space of the insulated box 8 is connected to the internal transmission channel of the base 1. When the material on the transmission component 4 is transmitted out from the base 1, it will first enter the insulated box 8. The temperature control device 81 is located on the upper part of the insulated box 8. The temperature control device 81 is connected to the internal space of the insulated box 8 through a pipe to achieve precise control of the temperature inside the insulated box.

[0031] A pre-cooling zone is separated within the material transfer channel by a partition 7. The glass first enters this pre-cooling zone for initial cooling. The pre-cooling zone effectively reduces the surface temperature of the glass, preparing it for subsequent cooling steps. After the glass leaves the pre-cooling zone, it enters an insulated box 8. The insulated box 8 is equipped with a temperature control device 81, which controls the temperature inside the box, forming a temperature transition zone. This prevents the cooled glass from directly contacting the outside environment and causing a large temperature difference, thus preventing stress changes and potential cracks caused by temperature differences. In addition, the presence of the insulated box 8 further optimizes the temperature gradient of the entire cooling system, ensuring that the glass remains in a suitable temperature environment throughout the cooling process, thereby improving glass quality and production efficiency.

[0032] In addition, such as Figure 1 and Figure 2As shown, it also includes a detection module 9 and a vision inspection instrument 91. The detection module 9 is located at the notch on the right side of the insulation box 8. The vision inspection instrument 91 is mounted on the detection module 9, with its detection probe facing the side of the transmission component 4. The vision inspection instrument 91 uses a high-precision camera to monitor the glass condition on the transmission component 4 in real time, ensuring that each piece of glass meets quality standards when leaving the insulation box 8. The detection module 9 and the vision inspection instrument 91 work together to automatically record the surface condition, dimensions, and other key parameters of the glass as it passes through. If any defects or abnormalities are detected, the system will immediately issue an alarm and take corresponding measures to ensure that only qualified products can continue to the next process. This intelligent detection mechanism not only improves the product qualification rate but also reduces the time and cost of manual inspection, enhancing the overall automation level of production.
