[0002] After high-temperature processing, thermal stress exists inside the glass. If it is not properly cooled, the thermal stress will cause defects such as cracks and deformation in the glass during the subsequent cooling process, affecting quality indicators such as the glass's flatness, optical properties, and mechanical strength.

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] As mentioned above, currently, natural cooling, air cooling technology or water cooling technology are mainly relied on. Uneven cooling by fans or blowers can easily lead to stress concentration. Direct water spraying may cause the glass to crack and residual water stains may affect the surface quality. Cooling too quickly can easily lead to stress concentration, while cooling too slowly can easily affect production efficiency. In addition, the contact between glass and air during transportation mainly depends on its own area, the thermal conductivity of air is poor, and the area radiating outward is fixed and limited.

[0022] In view of this, the present invention provides a cooling device for glass production and processing, which can be assembled by placing an air cooling mechanism, a spray cooling component and a heat-conducting contact component on a spliced ​​conveying platform, thereby increasing the contact area between the glass and the outside air during the glass transportation process, and increasing the efficiency of natural cooling. The cross-directional cooling of the air cooling mechanisms on the upper and lower sides can reduce the unevenness of wind cooling, and the spray cooling component is set between the two air cooling mechanisms. While the glass is cooled in a combined manner, the glass after spray cooling can also be dried. Reduce the impact of water stains on the glass surface caused by spray cooling.

[0023] Combine the following Figure 1 to Figure 16 The present invention is described in detail.

[0024] First embodiment: like Figure 1 to Figure 16 As shown, the present invention provides a cooling device, in particular, a cooling device for glass production and processing. In this embodiment, the cooling device includes a conveying platform 1, a transmission component 2, an air cooling mechanism 3, a spray cooling component 4, a heat-conducting contact component 5, a conveying roller 6, an installation cavity 7 and a slide rail 8. Among them, a number of evenly distributed conveying rollers 6 are arranged between the baffles on the two sides of the conveying platform 1, and the rotating shafts at both ends of the conveying roller 6 are tubular. The two ends of the conveying roller 6 are respectively connected to the inner side of the two baffles of the conveying platform 1 through the tubular rotating shaft, and the conveying roller 6 can rotate. The installation cavity 7 is opened inside the baffles on the two sides of the conveying platform 1, and the interior of the installation cavity 7 on one side of the conveying platform 1 is used to install the transmission component 2 that drives the conveying roller 6 to rotate synchronously. As shown Figure 1As shown, the conveying platforms 1 can be spliced ​​together to increase the conveying distance and the cooling time of the glass. Slide rails 8 are installed on the upper side of the baffles on both sides of the conveying platform 1, and a detachable air cooling mechanism 3 and a spray cooling component 4 are set on the conveying platform 1. The air cooling mechanism 3 and the spray cooling component 4 are both distributed up and down, and the processed glass plate is cooled synchronously in the up and down directions to increase the cooling efficiency. A heat conduction contact component 5 is also set between the conveying rollers 6 to increase the heat radiation of the glass plate to the outside during transportation.

[0025] like Figure 1~Figure 3 As shown, the transmission assembly 2 includes a driving shaft 201, a driving bevel gear 202, a driven bevel gear 203 and a bidirectional motor 204. The driving shaft 201 is arranged in the installation cavity 7 on one side of the conveying platform 1, and the two ends of the driving shaft 201 are respectively connected to the front and rear sides of the installation cavity 7 for rotation. A plurality of evenly distributed driven bevel gears 203 are arranged on the side of the installation cavity 7 where the driving shaft 201 is arranged, close to the conveying roller 6, and the driven bevel gears 203 are connected to the side wall of the installation cavity 7 for rotation. The driven bevel gears 203 are respectively connected to the rotating shaft part of the conveying roller 6 extending to the interior of the installation cavity 7, and the conveying roller 6 is driven to rotate by the driven bevel gears 203. A plurality of evenly distributed driving bevel gears 202 are arranged on the driving shaft 201, and the driving bevel gears 202 are meshed with the corresponding driven bevel gears 203 in a one-to-one correspondence. The driving shaft 201 is driven by a bidirectional motor 204 installed at the front or rear end of a baffle on one side of the conveying platform 1 , and the output end of the bidirectional motor 204 and the driving shaft 201 are fixedly connected together.

[0026] The air cooling mechanism 3 includes two parts, the upper and lower parts. The air cooling mechanism 3 sandwiches the glass plate in the middle, and cools the upper and lower surfaces of the glass plate at the same time, thereby increasing the cooling efficiency. The upper air cooling mechanism 3 includes a first moving frame 301. A wind box 302 is arranged on the upper side of the outer part of the first moving frame 301. An air outlet nozzle 303 is fixedly connected to the lower side of the outer part of the wind box 302. The wind box 302 is composed of a spliced ​​semi-enclosed box body, a ventilation duct, and a fan. The fan extracts gas from the outside of the box body and sends it into the inside of the box body through the ventilation duct. There is an opening at the lower end of the outer part of the box body, so that the air outlet nozzle 303 and the inside of the box body are connected together. The pipe end of the lower end of the air outlet nozzle 303 is bent forward, so that the airflow used by the upper air cooling mechanism 3 to cool the glass plate forms a certain angle with the surface of the glass plate, thereby increasing the contact area with the surface of the glass plate and reducing the contact dead angle. In addition, the rollers arranged at the four corners of the lower end of the first moving frame 301 are all stuck in the inside of the slide rails 8 at the upper ends of the baffles on both sides of the conveying platform 1. The front and rear positions of the air cooling mechanism 3 can be conveniently adjusted through the first movable frame 301 , and the roller at the lower end of the first movable frame 301 has a locking function, which facilitates fixing the first movable frame 301 .

[0027] A wind cooling mechanism 3 is also provided on the lower side of the conveying platform 1. The wind cooling mechanism 3 on the lower side includes two lateral fans 304 provided on one side of the lower end of the conveying platform 1. The lateral fans 304 are located below the first movable frame 301, and an air outlet 305 is provided at the upper end of the lateral fans 304 near the conveying roller 6. Several uniformly distributed air guide plates 306 are provided inside the air outlet 305. The air guide plates 306 are tilted upward at one end near the conveying roller 6 to guide the airflow sent out from the air outlet 305. The airflow blown out from the lower end to the bottom surface of the glass plate is contacted with the glass plate in an inclined manner, thereby increasing the contact area with the bottom of the glass plate. A second air filter plate 11 is arranged inside the lateral fan 304 near the air outlet 305. The second air filter plate 11 is tilted upward toward one side of the conveying roller 6, and cooperates with the air guide plate 306 to filter the air flow blown out from the air outlet 305 to avoid impurities adhering to the surface of the glass due to its stickiness when it is high in temperature, which may affect the quality of the finished glass plate.

[0028] A first air filter plate 10 is arranged inside the wind box 302, and air guide blocks 9 are arranged at the front and rear positions of the lower end of the wind box 302. The air guide blocks 9 collect the airflow transported from the upper ventilation duct to the direction of the air outlet nozzle 303 of the wind box 302. The first air filter plate 10 is on the upper side of the air guide block 9, and filters the airflow ejected from the air outlet nozzle 303 to prevent excessive impurities in the airflow from adhering to the surface of the glass plate and affecting the quality of the glass plate product. The surface of the glass plate is cooled by wind through the upper and lower air cooling mechanisms 3. The upper air cooling mechanism 3 blows airflow from the back to the front to the upper surface of the glass plate, and the lower air cooling mechanism 3 blows airflow from one side to the other side to the lower surface of the glass plate, cooling the glass plate from the upper and lower directions. The contact area between the airflow and the glass plate is increased, and the efficiency of wind cooling on the glass plate is increased.

[0029] like Fig.10 and Fig.13 As shown, since air is a medium with poor thermal conductivity, the cooling effect is poor if the glass plate is cooled naturally during transportation or by wind cooling alone, and the heat inside the glass plate is slowly radiated outward. Therefore, a spray cooling component 4 is also provided on the conveyor platform 1. Among them, the spray cooling component 4 is also divided into two parts, the upper and lower parts, and can simultaneously perform spray cooling treatment on the upper and lower surfaces of the glass plate. The spray cooling component 4 in the upper half of the conveyor platform 1 includes a second movable frame 401, and the rollers at the four corners of the lower end of the second movable frame 401 are also stuck in the interior of the slide rails 8 at the upper ends of the baffles on both sides of the conveyor platform 1. A water collecting tank 402 is fixedly connected to the external upper end of the second movable frame 401, and a number of evenly arranged atomizing nozzles 403 are fixedly connected to the external lower side of the water collecting tank 402, as shown in FIG. Fig.11As shown in the example, two rows of atomizing nozzles 403 are arranged at the lower end of the outer portion of the water collecting tank 402, and the two rows of atomizing nozzles 403 are staggered with each other to increase the spraying range of the atomizing nozzles 403 on the surface of the glass plate and reduce cooling dead angles.

[0030] In order to convey water to the inside of the water collecting tank 402, a water pump 404 is fixedly connected to the upper end of the outer part of the water collecting tank 402, and a water pumping pipe 405 is fixedly connected to the upper end of the water pump 404. The water pumping pipe 405 is in an inverted mountain shape, with the middle pipeline facing downward and fixedly connected to the upper end of the water pump 404. The two ends of the water pumping pipe 405 are bent downward, and a water delivery hose 407 is fixedly connected to both ends of the water pumping pipe 405. The lower end of the water delivery hose 407 is connected to the water storage tank 406 arranged on both sides of the conveying platform 1. In order to convey the water flow through the water pumping pipe 405, a filter plate is arranged inside the water collecting tank 402 to pre-filter the water flow entering the atomizing nozzle 403. It can prevent the impurities in the water flow from clogging the nozzle, and it can also prevent the impurities in the water mist from affecting the quality of the glass. A filtering structure is also required to be added at the connection between the water delivery hose 407 and the water storage tank 406 to filter the water pumped into the water collection tank 402 in advance.

[0031] In order to spray water to cool the lower surface of the glass plate from below, a water tank 408 is arranged below the conveying platform 1. The upper end of the water tank 408 is open, and a cross-shaped mounting bracket 409 is arranged at the upper position inside the water tank 408. An extraction pump 410 is fixedly connected to the middle position of the upper end of the mounting bracket 409. A connecting pipe 411 is fixedly connected to the lower end of the extraction pump 410, and the lower end of the connecting pipe 411 extends all the way to the inner bottom end of the water tank 408. A filter frame 12 is arranged in the middle of the inner lower end of the connecting pipe 411, and the lower end of the connecting pipe 411 extends to the inside of the filter frame 12, and the filtered water is extracted from the inside of the filter frame 12 through the connecting pipe 411. A water separation box 412 is rotatably connected to the upper end of the extraction pump 410, and the interior of the water separation box 412 and the water outlet of the extraction pump 410 are through-connected together. A vertical straight spray pipe 414 is fixedly connected to the upper center of the water separation box 412, and a plurality of evenly distributed water spray bends 413 are fixedly connected to the upper edge of the water separation box 412, and the upper ends of the water spray bends 413 are bent and tilted in one direction, such as Fig.12 As shown, the upper ends of the annularly distributed water spray bends 413 are bent in the counterclockwise direction, so that when the water spray bends 413 spray water mist outward, the water diversion box 412 can be rotated through the reaction force, and the water mist sprayed by the straight spray pipe 414 at the center of the water spray bend 413 is diffuse, covering the lower surface of the glass plate as completely as possible.

[0032] The water storage tank 406, the water collection tank 402 and the water tank 408 have a heat preservation function, and the temperature of the water stored in the water storage tank 406 and the water tank 408 is controlled at 15-25°C. On the one hand, it can prevent the water mist sprayed on the glass plate due to the low water temperature from having a large temperature difference with the glass plate, causing the temperature of the glass surface to drop sharply, generating a large thermal stress inside the glass, and causing the glass to crack or break. On the other hand, not using water with too high a temperature can reduce the large amount of evaporation caused by the water mist sprayed on the glass surface, and avoid the extension of the processing cycle caused by the slowdown of the cooling speed of the glass.

[0033] When cooling the processed glass plate, the two conveying tables 1 can be selectively moved according to the specific cooling form and processing technology. Figure 1 As shown in the figure, the first moving frame 301, the second moving frame 401 and the first moving frame 301 are sequentially placed on the upper side of the conveyor 1 from front to back, the second moving frame 401 is placed in the middle, and the upper air cooling mechanism 3 is installed on the first moving frame 301. At the position corresponding to the upper air cooling mechanism 3, a lateral fan 304 is installed on the same side below the conveyor 1, and the lateral fan 304 cools the lower surface of the glass plate. The wind box 302 on the upper side of the first moving frame 301 blows air downward through the air outlet nozzle 303 to cool the upper surface of the glass plate in an inclined direction. The upper spray cooling component 4 is installed on the upper side of the second moving frame 401. Below the conveyor platform 1, a water tank 408 and other lower-layer spray cooling components 4 are placed in a position aligned with the upper-layer spray cooling components 4. During the backward conveying process, the glass plate is first conveyed by the conveyor platform 1 and naturally cooled by the external air. Then, the high-temperature glass plate is sent to the area where the air cooling mechanism 3 is located. After being blown by the airflow, the temperature of the glass plate drops slightly.

[0034] After the glass plate that has been cooled for the first time continues to move backwards for a certain distance and enters the area of ​​the spray cooling component 4, the atomizing nozzle 403 and the water spray elbow 413 and the straight spray pipe 414 under the conveyor 1 spray water mist upwards to cool the upper and lower surfaces of the glass plate. After preliminary wind cooling and two stages of natural cooling, combined with a cooling liquid medium of 15-25°C, the temperature difference between the glass plate and the cooling medium is further reduced. To prevent the water temperature from being too low, the temperature difference between the water mist sprayed onto the glass plate and the glass plate is large, causing the temperature of the glass surface to drop sharply, generating large thermal stress inside the glass, and causing the glass to crack or break. After the cooling of the spray cooling component 4 is completed, as the conveyor 1 continues to be transported backwards, the glass plate with water mist attached to the surface enters the area of ​​the wind cooling mechanism 3 on the back side, and the water mist on the glass surface is evaporated and further cooled.

[0035] Second embodiment: like Figure 1 and Fig.16 A heat-conducting contact component 5 is also provided on the conveying platform 1, and the heat-conducting contact component 5 includes a metal heat-conducting sheet 501 and a heat-dissipating fin 502 on the lower side of the metal heat-conducting sheet 501. Several metal heat-conducting sheets 501 are evenly distributed between the conveying rollers 6, and a metal heat-conducting sheet 501 is provided between every two conveying rollers 6 adjacent to each other. The metal heat-conducting sheets 501 are made of copper or other metals with good heat-conducting properties. Both ends of the metal heat-conducting sheets 501 extend to the inside of the mounting cavities 7 on both sides of the conveying platform 1. Through the ventilation slots 14 opened on the side away from each other in the mounting cavities 7, the heat absorbed by the metal heat-conducting sheets 501 is assisted in heat dissipation. Several evenly distributed heat-dissipating fins 502 are fixedly connected to the lower side of the metal heat-conducting sheets 501 to increase the contact area between the metal heat-conducting sheets 501 and the air, so as to facilitate heat dissipation. The upper surface of the metal heat-conducting sheet 501 is lower than the lower surface of the glass plate, so as to avoid the upper surface of the metal heat-conducting sheet 501 contacting the lower surface of the glass plate and causing scratches on the glass plate.

[0036] In order to further increase the heat exchange between the glass sheet and the air during the conveying process, a number of evenly distributed through holes are opened on the surface of the conveying roller 6, such as Fig.15 As shown, the interior of the entire conveying roller 6 is hollow, and the tubular rotating shafts at both ends of the conveying roller 6 and the interior of the mounting cavity 7 on both sides of the conveying platform 1 are connected, and the heat transferred to the interior of the conveying roller 6 is dissipated through the ventilation slots 14. A conveying rubber sleeve 13 is evenly arranged on each conveying roller 6. The conveying rubber sleeve 13 can increase the static friction with the bottom surface of the glass plate on the one hand, and ensure the stable conveying of the glass plate. The conveying rubber sleeves 13 on the two adjacent conveying rollers 6 are arranged in a staggered manner to increase the stability of the contact.

[0037] The glass plate is placed on the conveying platform, and after contact and rolling transportation by the conveying rubber sleeve 13, the glass plate moves backward, and after preliminary cooling by the air cooling mechanism 3, the glass plate enters the area where the spray cooling component 4 is located. After cooling by the cooling medium of 15~25℃, the glass plate enters the interior of the next air cooling mechanism 3 to evaporate and clean the water mist on the surface of the glass plate. After the glass plate is processed by the last air cooling mechanism 3, it is necessary to place a device for stacking the cooled glass plates at the tail end of the spliced ​​conveying platform 1. The bidirectional motor 204, the bellows 302, the lateral fan 304, the water pump 404, the extraction pump 410, and the temperature control system in the water tank 406 and the water tank 408 in the cooling device are all connected to the PLC control system for synchronous control. The conveying platform 1 can be spliced ​​and combined, and the conveying platform 1 can realize a variety of different cooling methods to cool the glass by combining with the air cooling mechanism 3 and the spray cooling component 4.

[0038] In summary, the cooling device for glass production and processing of the present invention has the following advantages: 1. Combine natural cooling, wind cooling and spray cooling to cool the glass. Before the glass comes into contact with the water mist, pre-treat the glass to reduce the temperature difference between the cooling medium and the glass. While ensuring the production cycle as much as possible, reduce the possibility of high thermal stress inside the glass.
