Description

Technical Field

[0002] At present, in the production process of float and other plate glass, the annealing kiln is an indispensable core device, which is used to control the thermal stress of the glass, so that the glass has appropriate permanent stress and temporary stress, and ensure the quality of the glass. In the actual annealing process, due to various reasons such as poor temperature control or high impurity content in the glass, the glass in the annealing kiln may explode, resulting in a large amount of glass fragments falling down. The current way to clean up glass fragments is generally to open the annealing kiln and manually clean up the glass fragments, but due to the limited space in the annealing kiln, cleaning is difficult, time-consuming and labor-intensive, the cleaning efficiency is low, and the cleaning effect is poor. In addition, a heating mechanism for controlling the annealing cooling rate is usually provided in the annealing kiln. If these glass fragments fall on the heating mechanism, it will affect the heat dissipation function of the heating mechanism, thereby affecting the annealing effect and increasing energy consumption.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0056] Please refer to Figures 1 to 3 The embodiment of the present invention provides a glass production device (not shown) for producing plate glass 300. It can realize automatic cleaning and transportation of glass fragments 400, saving time and labor, high cleaning efficiency, good cleaning effect, and can avoid the glass fragments 400 from affecting the heating mechanism, thereby ensuring the annealing effect.

[0057] The glass production equipment includes a forming device (not shown) and an annealing device 100. The forming device is connected to the annealing device 100. The forming device is used to produce formed plate-shaped glass 300, and the obtained multiple high-temperature plate-shaped glasses 300 are sequentially sent to the annealing device 100. The annealing device 100 is used to continuously anneal the multiple plate-shaped glasses 300. The annealing efficiency is high. The annealing device 100 can control the thermal stress of the plate-shaped glass 300 so that the plate-shaped glass 300 has appropriate permanent stress and temporary stress, thereby ensuring the product quality of the plate-shaped glass 300.

[0058] The annealing device 100 includes a first annealing furnace section 110, a conveying roller 120, a slag transport mechanism 130, a first heating mechanism 150, a second heating mechanism 160, a cooling mechanism 170, a curtain mechanism 180 and a temperature sensor 190. The conveying roller 120, the slag transport mechanism 130 and the first heating mechanism 150 are all installed in the first annealing furnace section 110, the first heating mechanism 150 is arranged below the conveying roller 120, the conveying roller 120 is used to transport the high-temperature plate glass 300 into the first annealing furnace section 110, and the first heating mechanism 150 is used to dissipate heat to the plate glass 300 to control the annealing cooling rate of the plate glass 300, thereby realizing precision annealing of the plate glass 300. Specifically, during the actual annealing process, due to various reasons such as poor temperature control or high impurity content in the plate-shaped glass 300, the plate-shaped glass 300 on the conveying roller 120 in the first annealing furnace section 110 may explode, generating a large number of glass fragments 400 and falling downward. In this embodiment, the slag transport mechanism 130 is arranged between the conveying roller 120 and the heating mechanism. The slag transport mechanism 130 is used to receive the glass fragments 400 formed by the plate-shaped glass 300 exploding during the annealing process to prevent the glass fragments 400 from falling onto the first heating mechanism 150 located below the conveying roller 120 under the action of gravity, thereby avoiding affecting the heat dissipation function of the first heating mechanism 150 and ensuring the annealing effect. The slag transport mechanism 130 is also used to send the glass fragments 400 out of the first annealing furnace section 110 to realize automatic cleaning and transportation of the glass fragments 400, saving time and labor, with high cleaning efficiency and good cleaning effect.

[0059] It should be noted that the second heating mechanism 160 is installed in the first annealing furnace section 110 and is arranged above the conveying roller 120. The second heating mechanism 160 is used to dissipate heat to the plate glass 300. The first heating mechanism 150 and the second heating mechanism 160 work together to simultaneously control the temperature of the plate glass 300 on the conveying roller 120 from both the upper and lower sides. The cooling mechanism 170 is installed in the first annealing furnace section 110 and is arranged above the conveying roller 120. The cooling mechanism 170 is used to blow outside air to the plate glass 300 on the conveying roller 120 to air-cool the plate glass 300, and can also realize the annealing temperature control function of the plate glass 300. Specifically, during the annealing process of the plate glass 300, by reasonably starting and stopping or controlling the operating power of the first heating mechanism 150, the second heating mechanism 160 and the cooling mechanism 170, the first heating mechanism 150, the second heating mechanism 160 and the cooling mechanism 170 work together to more accurately control the annealing cooling rate of the plate glass 300 and ensure the annealing effect.

[0060] Furthermore, a curtain blocking mechanism 180 is installed at the end of the first annealing furnace section 110 and is arranged above the conveying roller 120 at intervals. The curtain blocking mechanism 180 is used to block the outside air to prevent the air from flowing inside and outside the first annealing furnace section 110, thereby ensuring the stability of the temperature field in the first annealing furnace section 110, which is conducive to achieving precision annealing. A temperature sensor 190 is installed in the first annealing furnace section 110. The temperature sensor 190 is used to detect the internal temperature of the first annealing furnace section 110, so as to accurately control the annealing temperature and improve the annealing effect.

This part of the conveyor belt 150 is pressed on the circumferential surface of the driving wheel 130 under the action of the pressure regulating roller 139. The second driving component 138 is used to drive the pressure regulating roller 139 to approach or move away from the driving wheel 133 to adjust the pressure of the conveyor belt 135 on the driving wheel 133, thereby adjusting the friction between the conveyor belt 135 and the driving wheel 133, ensuring that the friction between the conveyor belt 135 and the driving wheel 133 is within a reasonable range, avoiding the friction between the conveyor belt 135 and the driving wheel 133 to be too large or too small, thereby avoiding the conveyor belt 135 from being torn, broken or slipped, and ensuring the conveying efficiency of the glass fragments 400.

The transmission rope 1384 is wound around the fixed pulley 1383. One end of the transmission rope 1384 is connected to the capstan 1382, and the other end is connected to the rotating rod 1385. The fixed pulley 1383 is used to adjust the movement direction of the transmission rope 1384.

[0068] Furthermore, the support shaft 1311 is arranged in the middle part of the rotating rod 1385, one end of the rotating rod 1385 is connected to the transmission rope 1384, and the other end is rotatably connected to the pressure regulating roller 139, and the second driving member 1381 is used to drive the rotating rod 1385 to rotate relative to the support shaft 1311 through the transmission rope 1384, so as to drive the pressure regulating roller 139 to rotate relative to the support shaft 1311, thereby making the pressure regulating roller 139 approach or move away from the driving wheel 133.

[0069] It should be noted that the rotating rod 1385 is extended in the vertical direction, the transmission rope 1384 is connected to the bottom end of the rotating rod 1385, the pressure regulating roller 139 is rotatably connected to the top end of the rotating rod 1385, and the second driving member 1381 and the driving wheel 133 are relatively arranged on both sides of the rotating rod 1385. When the second driving member 1381 drives the capstan 1382 to rotate, the transmission rope 1384 is wound around the capstan 1382, and the length of the transmission rope 1384 outside the capstan 1382 is shortened to pull the rotating rod 1385 to rotate relative to the support shaft 1311, so that the pressure regulating roller 139 moves in the direction close to the driving wheel 133, thereby increasing the pressure of the conveyor belt 135 on the driving wheel 133 and increasing the friction between the conveyor belt 135 and the driving wheel 133; when the second driving member 1381 drives the capstan 1382 to rotate in the opposite direction When the conveyor belt 135 is moving, the capstan 1382 loosens the transmission rope 1384, and the length of the transmission rope 1384 outside the capstan 1382 increases. At this time, the conveyor belt 135 drives the pressure regulating roller 139 to move away from the driving wheel 133 under the action of its own tension force, so as to reduce the pressure of the conveyor belt 135 on the driving wheel 133, thereby reducing the friction between the conveyor belt 135 and the driving wheel 133. During this process, the rotating rod 1385 rotates in the opposite direction relative to the support shaft 1311 until the transmission rope 1384 outside the capstan 1382 is straightened.

[0070] In this embodiment, the second drive component 138 drives the rotating rod 1385 to rotate relative to the support shaft 1311 through rope transmission, so that the pressure regulating roller 139 is close to or away from the driving wheel 133, thereby adjusting the pressure of the conveyor belt 135 on the driving wheel 133, but it is not limited to this. In other embodiments, the second drive component 138 can also drive the rotating rod 1385 to rotate relative to the support shaft 1311 through screw transmission, and the transmission method of the second drive component 138 is not specifically limited.

[0071] Please refer to Figure 6 and Figure 7 In this embodiment, the conveyor belt 135 is a mesh belt, and the conveyor belt 135 is densely provided with a plurality of mesh holes 1353 to reduce the weight of the entire conveyor belt 135, realize the lightweight of the conveyor belt 135, and facilitate long-distance transportation. The conveyor belt 135 with the mesh holes 1353 will not affect the heat transfer in the first annealing furnace section 110, and the annealing effect is guaranteed. Specifically, the width of the conveyor belt 135 ranges from 1 meter to 8 meters, and the width of the conveyor belt 135 is greater than the width of the plate glass 300. A reasonable width of the conveyor belt 135 can ensure that the glass fragments 400 falling from the conveyor roller 120 are completely received, and the situation of missing the glass fragments 400 is prevented.

[0072] Furthermore, the mesh 1353 is rectangular, the length of the mesh 1353 ranges from 15 mm to 50 mm, the width of the mesh 1353 ranges from 5 mm to 25 mm, and the size of the mesh 1353 is smaller than the size of the glass fragments 400. Reasonable length and width of the mesh 1353 can ensure the bearing effect on the glass fragments 400 and prevent the glass fragments 400 from falling through the mesh 1353.

[0073] The conveyor belt 135 includes a plurality of spiral buckles 1354 and a plurality of connecting rods 1355. The plurality of spiral buckles 1354 are arranged side by side and staggered, and the connecting rod 1355 passes through two adjacent spiral buckles 1354 at the same time and can rotate relative to the spiral buckles 1354, that is, two spiral buckles 1354 are connected by a connecting rod 1355 to prevent the two spiral buckles 1354 from separating, and the two spiral buckles 1354 can rotate relative to the connecting rod 1355 to ensure that the conveyor belt 135 can move under the drive of the driving wheel 133 and the driven wheel 134. Specifically, the connecting rod 1355 is detachably connected to the spiral buckle 1354, and the user can select the number of spiral buckles 1354 and connecting rods 1355 according to actual conditions to adjust the length of the conveyor belt 135.

[0074] In this embodiment, the spiral ring 1354 is in a rectangular ring shape, that is, the mesh 1353 formed by the spiral ring 1354 is in a rectangular shape. The cross section of the spiral ring 1354 is circular, and the diameter of the cross section of the spiral ring 1354 is in a circular range of 1 mm to 4 mm; the connecting rod 1355 is in a cylindrical shape, and the diameter of the connecting rod 1355 is in a range of 1.5 mm to 5 mm; the reasonable diameter of the cross section of the spiral ring 1354 and the diameter of the connecting rod 1355 can ensure the strength and structural stability of the conveyor belt 135, and ensure the stability of conveying the glass fragments 400.

[0075] In this embodiment, the spiral ring buckle 1354 and the connecting rod 1355 are both made of stainless steel material, but it is not limited to this. In other embodiments, the spiral ring buckle 1354 and the connecting rod 1355 can be both made of metal material or both made of plastic. There is no specific limitation on the material of the spiral ring buckle 1354 and the connecting rod 1355.

[0076] Please refer to Figure 8It should be noted that the frame 131 is provided with a limit frame 1313 having a guide rail 1312, the guide rail 1312 is extended in the vertical direction, the tensioning roller 140 is slidably matched with the guide rail 1312, and can rotate relative to the guide rail 1312, the conveyor belt 135 is arranged in close contact with the tensioning roller 140, and is arranged at the bottom of the tensioning roller 140, the conveyor belt 135 supports the tensioning roller 140, and the weight of the tensioning roller 140 is borne on the conveyor belt 135 to realize the tensioning function of the conveyor belt 135, and the conveyor belt 135 can drive the tensioning roller 140 to rotate relative to the guide rail 1312 to ensure the stability of the conveyor belt 135 during the conveying process.

[0077] In this embodiment, the weight of the tension roller 140 is borne on the conveyor belt 135 to achieve the tensioning function of the conveyor belt 135. However, it is not limited to this. In another embodiment, a counterweight is hung on the tension roller 140, and the weight of the counterweight and the tension roller 140 are jointly borne on the conveyor belt 135 to further ensure the tensioning of the conveyor belt 135; in another embodiment, an electric cylinder is installed on the limit frame 1313, and the electric cylinder is connected to the tension roller 140. The electric cylinder drives the tension roller 140 to slide relative to the guide rail 1312 to adjust the tensioning force of the tension roller 140 on the conveyor belt 135 to ensure that the conveyor belt 135 is in a tensioned state.

[0078] In this embodiment, the guide roller 141 is rotatably mounted on the frame 131, and the conveyor belt 135 is arranged in close contact with the guide roller 141. The guide roller 141 is used to guide and limit the conveyor belt 135 to prevent the conveyor belt 135 from deflecting or tilting.

[0079] Furthermore, there are multiple tensioning rollers 140 and multiple limit frames 1313, and multiple guide rollers 141. Multiple tensioning rollers 140 and multiple guide rollers 141 are alternately arranged in sequence to ensure the tensioning and guiding effects on the conveyor belt 135, thereby further improving the stability of the movement of the conveyor belt 135.

[0080] Please refer to Fig. 9The conveying roller 120 includes a third driving assembly 121 and a plurality of rotating rollers 122. The plurality of rotating rollers 122 are arranged in parallel and at equal intervals, and are all rotatably installed in the first annealing furnace section 110. The plurality of rotating rollers 122 work together to drive the plate glass 300 to be fed forward. The third driving assembly 121 is connected to the plurality of rotating rollers 122 at the same time, and the third driving assembly 121 is used to simultaneously drive the plurality of rotating rollers 122 to rotate relative to the first annealing furnace section 110. Specifically, a leakage gap 123 is formed between two adjacent rotating rollers 122, and the leakage gap 123 is used for allowing the glass fragments 400 to fall to the slag transport mechanism 130 to prevent the glass fragments 400 from adhering to the rotating rollers 122. The leakage gap 123 is also used for allowing heat to pass through to ensure the accuracy of temperature control in the first annealing furnace section 110.

[0081] In this embodiment, the plurality of rotating rollers 122 are divided into a plurality of groups, and each group of rotating rollers 122 has at least one rotating roller. The third driving assembly 121 includes a plurality of third driving members 1211 and a plurality of reduction boxes 1212, each third driving member 1211 is connected to a reduction box 1212, each reduction box 1212 is connected to a group of rotating rollers 122, and each third driving member 1211 is frequency-controlled by a frequency converter to achieve independent control of the rotation speed of each group of rotating rollers 122, thereby achieving differentiated control of the rotation speed, and facilitating accurate control of the conveying speed of the plate-shaped glass 300.

[0082] Please refer to Fig.10 and Fig.11 It is worth noting that a guide plate 1111 is provided on the inner side of the top wall of the first annealing kiln section 110, that is, the guide plate 1111 is provided in the internal cavity 114 of the kiln body 111 and is connected to the top of the kiln body 111. The guide plate 1111 is provided with a plurality of guide holes 1112, which are arranged in parallel and spaced apart. The guide holes 1112 are extended along the conveying direction of the conveying roller 120. The guide holes 1112 are used to guide the internal air in the internal cavity 114 to limit the flow direction of the internal air, avoid turbulence of the internal air, ensure the stability of the internal temperature field, improve the annealing effect, and facilitate the realization of precision annealing.

[0083] For ease of understanding, the arrangement direction of the plurality of guide holes 1112 is indicated as the first direction, that is, the plurality of guide holes 1112 are arranged in parallel and spaced apart along the first direction, and the conveying direction of the conveying roller 120 and the slag conveying mechanism 130 is indicated as the second direction, and the first direction is perpendicular to the second direction. Further, the plate glass 300 enters the kiln body 111 of the first annealing furnace section 110 along its length direction, the length direction of the plate glass 300 is the second direction, and the width direction of the plate glass 300 is the first direction.

[0084] It should be noted that during the annealing process, the internal temperature of the kiln body 111 is different in the second direction, so that the annealing temperature of the plate glass 300 at different positions in the kiln body 111 is different, thereby ensuring the annealing effect. Furthermore, since the annealing temperatures at different positions in the kiln body 111 are different, the air in the kiln body 111 has a tendency to flow from a low temperature position to a high temperature position. In this embodiment, since the guide plate 1111 connected to the top of the kiln body 111 is provided with a guide hole 1112 extending along the second direction, the air in the annealing kiln shell will flow along the guide hole 1112 in the second direction and flow from a low temperature position to a high temperature position. In this way, turbulence of the air in the annealing kiln shell can be effectively avoided, which facilitates the precise control of the annealing temperature, and is also beneficial to energy saving and improving economic benefits.

[0085] Furthermore, there are multiple guide plates 1111, and the multiple guide plates 1111 are arranged in parallel and spaced apart along the second direction, and the guide holes 1112 on the multiple guide plates 1111 are arranged in an aligned manner, so that air at different positions in the kiln body 111 flows into the guide holes 1112 from between two adjacent guide plates 1111, and then flows along the guide holes 1112 toward the position with higher temperature, thereby ensuring the smoothness and stability of the air flow in the kiln body 111. Specifically, the multiple guide holes 1112 on two adjacent guide plates 1111 are arranged in a one-to-one correspondence, and the air flowing out of the guide holes 1112 of one guide plate 1111 can continue to flow along the second direction to the corresponding guide holes 1112 of the next guide plate 1111, with a good guide effect, and can effectively avoid the occurrence of turbulence.

[0086] In this embodiment, the spacing between any two adjacent guide holes 1112 on the guide plate 1111 is the same, and the apertures of the multiple guide holes 1112 are the same. Specifically, the spacing between two adjacent guide holes 1112 ranges from 100 mm to 500 mm. A reasonable spacing between two adjacent guide holes 1112 can ensure that the air in the annealing furnace shell can quickly enter the guide hole 1112 close to it in the first direction, thereby ensuring the guide effect. The aperture of the guide hole 1112 ranges from 100 mm to 300 mm. A reasonable aperture of the guide hole 1112 can reduce the air flow speed as much as possible while ensuring the guide effect, so as to achieve accurate control of the annealing temperature.

[0087] It is worth noting that the processed plate-shaped glass 300 is thinner in the middle and thicker on both sides in the first direction, resulting in a faster heat dissipation rate in the middle of the plate-shaped glass 300 and a slower heat dissipation rate on both sides. After the conveying roller 120 delivers the processed plate-shaped glass 300 into the kiln body 111, in the first direction, since the heat dissipation rate in the middle of the plate-shaped glass 300 is faster and the heat dissipation rate on both sides is slower, the position corresponding to the middle of the plate-shaped glass 300 in the internal cavity 114 has a higher air temperature, higher molecular activity, faster air flow rate, and larger air flow rate, while the air temperature in the positions corresponding to the two sides of the plate-shaped glass 300 is lower, the molecular activity is lower, the air flow rate is slower, and the air flow rate is smaller. Therefore, in another embodiment, the spacing between two adjacent guide holes 1112 first decreases and then increases in the first direction, that is, the density of the multiple guide holes 1112 first increases and then decreases in the first direction. In other words, in the first direction, the guide holes 1112 in the middle of the guide plate 1111 are denser, and the guide holes 1112 on both sides are sparser. In this way, the denser guide holes 1112 in the middle of the guide plate 1111 can guide the larger flow of air at the corresponding position in the middle of the plate-shaped glass 300, and the sparser guide holes 1112 on both sides of the guide plate 1111 can guide the smaller flow of air at the corresponding positions on both sides of the plate-shaped glass 300, so as to ensure the guide effect. In another embodiment, the aperture of the guide hole 1112 increases first and then decreases in a first direction, that is, in the first direction, the aperture of the guide hole 1112 in the middle of the guide plate 1111 is larger, and the aperture of the guide holes 1112 on both sides is smaller. In this way, the guide hole 1112 with a larger aperture in the middle of the guide plate 1111 can guide a larger flow of air at a corresponding position in the middle of the plate-shaped glass 300, and the guide holes 1112 with a smaller aperture on both sides of the guide plate 1111 can guide a smaller flow of air at corresponding positions on both sides of the plate-shaped glass 300, thereby also ensuring the guide effect.

[0088] It should be noted that an exhaust port 1113 is provided on the top wall of the kiln body 111 in the first annealing kiln section 110. The exhaust port 1113 is arranged between two adjacent guide plates 1111. The exhaust port 1113 is used to discharge the air in the internal cavity 114 to the outside to achieve a pressure relief function. The exhaust port 1113 can discharge the air in the kiln body 111 when the air flows from a low-temperature position to a high-temperature position, so as to avoid the chimney effect of the air in the kiln body 111, further ensure the stability of the temperature field inside the kiln body 111, and improve the annealing effect.

[0089] In this embodiment, the exhaust port 1113 is connected to an exhaust pipe 1114, and the air in the internal cavity 114 can be discharged to the outside through the exhaust port 1113 and the exhaust pipe 1114 in sequence. Specifically, the exhaust pipe 1114 is provided with an air volume regulating valve 1115, which is used to adjust the flow rate of air discharged to the outside, so as to adjust the pressure relief rate and improve the accuracy of temperature control.

[0090] Furthermore, the spacing between two adjacent guide plates 1111 ranges from 200 mm to 800 mm. A reasonable spacing between two adjacent guide plates 1111 can facilitate the opening of the exhaust port 1113 and the installation of the exhaust pipe 1114. The exhaust pipe 1114 and the exhaust port 1113 have the same diameter, and the diameter of the exhaust pipe 1114 ranges from 200 mm to 500 mm. A reasonable diameter of the exhaust pipe 1114 can adjust the exhaust flow rate within a larger range, further improving the accuracy of temperature control.

[0091] In the present embodiment, there are multiple exhaust ports 1113 and multiple exhaust pipes 1114, and the multiple exhaust ports 1113 are spaced apart along the first direction. Each exhaust port 1113 is connected to an exhaust pipe 1114, and each exhaust pipe 1114 is provided with a gas volume regulating valve 1115. By adjusting the exhaust flow rate of each gas volume regulating valve 1115, the internal cavity 114 can be exhausted in a zoned manner, thereby achieving overall precise control of the annealing temperature.

[0092] Please refer to Fig.12 The first heating mechanism 150 includes a fixed frame 151 and an electric heating element 152. The electric heating element 152 is installed in the fixed frame 151, which is connected to the kiln body 111 of the first annealing furnace section 110 and is arranged below the conveying roller 120 in parallel and spaced apart. The fixed frame 151 is used to support and fix the electric heating element 152. The electric heating element 152 is used to dissipate heat after being powered on to adjust the annealing cooling rate of the plate glass 300.

[0093] Further, there are multiple electric heating elements 152, which are extended along the conveying direction of the conveying roller 120, and are arranged in parallel and spaced apart in the fixed frame 151, that is, the multiple electric heating elements 152 are arranged in parallel and spaced apart along the first direction, and the extending direction of the electric heating elements 152 is the second direction. The multiple electric heating elements 152 work together to enhance the heat dissipation effect and ensure the annealing effect.

[0094] It is worth noting that since the plate glass 300 formed by production is thinner in the middle and thicker on both sides in the first direction, the heat dissipation rate in the middle of the plate glass 300 is faster and the heat dissipation rate on both sides is slower. Therefore, the temperature in the middle of the plate glass 300 is lower and the temperature on both sides is higher. In order to ensure the annealing effect of the plate glass 300 and prevent the cooling speed on both sides of the plate glass 300 from being too fast, it is necessary to control the annealing cooling temperature of the middle of the plate glass 300 to be lower than the annealing cooling temperature on both sides of the plate glass 300.

[0095] In this embodiment, the spacing between two adjacent electric heating elements 152 is equal or gradually increases in the direction from the edge to the middle of the conveying roller 120, that is, in the first direction, the number of electric heating elements 152 corresponding to the middle position of the plate-shaped glass 300 is small and the distribution is sparse, and the number of electric heating elements 152 corresponding to the edge position of the plate-shaped glass 300 is large and the distribution is dense. In this way, multiple electric heating elements 152 work together to provide a small amount of heat to the middle of the plate-shaped glass 300 and a large amount of heat to the edge of the plate-shaped glass 300, ensuring that the annealing cooling temperature of the middle of the plate-shaped glass 300 is lower than the annealing cooling temperature of both sides of the plate-shaped glass 300.

[0096] In this embodiment, multiple electric heating elements 152 are divided into multiple groups, and the number of electric heating elements 152 in each group is at most two. The multiple groups of electric heating elements 152 are arranged in sequence along the second direction. The two electric heating elements 152 in each group are arranged opposite to each other in the first direction and are respectively connected to the two side walls of the kiln body 111 to facilitate maintenance and replacement.

[0097] The electric heating element 152 includes an insulating column 1521 and a resistance wire 1522. The insulating column 1521 is installed in the fixed frame 151, and the extension direction of the insulating column 1521 is the second direction. The fixed frame 151 is used to fix the position of the insulating column 1521. The resistance wire 1522 is wound around the outer surface of the insulating column 1521. The resistance wire 1522 is used to dissipate heat after power is turned on to control the annealing cooling rate of the plate glass 300.

[0098] In this embodiment, the specific structure of the second heating mechanism 160 is the same as the specific structure of the first heating mechanism 150, and will not be repeated here.

[0099] Please refer to Fig.13The cooling mechanism 170 includes a fan 171, a bellows 172 and an air inlet pipe 173. The bellows 172 is installed in the kiln body 111 of the first annealing furnace section 110 and is arranged above the conveying roller 120. One end of the fan 171 is connected to the outside, and the other end is connected to the bellows 172. A ventilation hole 1721 is arranged at the bottom of the bellows 172. The position of the ventilation hole 1721 corresponds to the position of the conveying roller 120. The fan 171 is used to generate negative pressure to suck the outside air into the bellows 172 and blow it toward the plate glass 300 on the conveying roller 120 through the ventilation hole 1721 at the bottom of the bellows 172 to achieve air cooling of the plate glass 300, thereby adjusting the annealing cooling rate of the plate glass 300.

[0100] Furthermore, the air inlet pipe 173 is connected between the fan 171 and the wind box 172, and the outside air sucked by the fan 171 can enter the wind box 172 through the air inlet pipe 173, and blow to the internal cavity 114 of the kiln body 111 through the ventilation hole 1721. Specifically, the air inlet pipe 173 is provided with an air volume regulating valve 174, and the air volume regulating valve 174 is used to adjust the flow rate of the outside air entering the internal cavity 114, so as to adjust the air volume for air cooling the plate-shaped glass 300 and improve the accuracy of temperature control.

[0101] In this embodiment, there are multiple fans 171 and multiple air inlet pipes 173, and the multiple air inlet pipes 173 are arranged at intervals along the first direction. Each air inlet pipe 173 is connected to a fan 171, and the multiple air inlet pipes 173 are connected to the bellows 172. Each air inlet pipe 173 is provided with an air volume regulating valve 174. By adjusting the air intake flow of each air volume regulating valve 174, zoned air cooling of the internal cavity 114 can be achieved, thereby achieving overall precise control of the annealing temperature.

[0102] It is worth noting that during the annealing process, the plate glass 300 is continuously fed forward along the second direction driven by the conveying roller 120 . During this process, in order to ensure the annealing effect of the plate glass 300 , the annealing cooling temperature of the plate glass 300 needs to be controlled to continuously decrease.

[0103] In this embodiment, there are multiple ventilation holes 1721, and the multiple ventilation holes 1721 are distributed in a rectangular array. The multiple ventilation holes 1721 work together to increase the air volume and improve the air cooling effect. Specifically, the density of the multiple ventilation holes 1721 is the same or gradually increases in the conveying direction of the conveying roller 120, that is, the density of the multiple ventilation holes 1721 is the same or gradually increases in the second direction, and the air cooling effect on the plate glass 300 is gradually enhanced in the second direction to ensure that the annealing cooling temperature of the plate glass 300 in the second direction continues to decrease.

[0104] Please refer to Fig.14The curtain blocking mechanism 180 includes a limit rod 181, a wind shield 182, a fourth driving assembly 183 and a lifting rod 184. The limit rod 181 is arranged at the end of the kiln body 111 in the first annealing kiln section 110, and is arranged above the conveying roller 120 at intervals. The extension direction of the limit rod 181 is perpendicular to the conveying direction of the conveying roller 120, that is, the limit rod 181 is extended along the first direction. Specifically, the wind shield 182 is provided with a sleeve 1821, which is sleeved outside the limit rod 181 and can rotate relative to the limit rod 181. The wind shield 182 is used to stop the airflow to prevent the outside air from flowing into the kiln body 111, and prevent the air in the kiln body 111 from flowing out, thereby avoiding the air circulation inside and outside the kiln body 111 of the first annealing kiln section 110, thereby ensuring the stability of the temperature field in the kiln body 111, ensuring the annealing effect, and facilitating the realization of precision annealing.

[0105] Furthermore, the end of the windshield 182 away from the limiting rod 181 is spaced apart from the conveying roller 120, and the gap between the windshield 182 and the conveying roller 120 is greater than the thickness of the plate glass 300. In the process of the conveying roller 120 conveying the plate glass 300, the windshield 182 will not interfere with the plate glass 300, that is, the windshield 182 will not affect the continuous annealing of the plate glass 300. In certain specific scenarios, the thickness of a certain position of the plate glass 300 is greater than the gap between the windshield 182 and the conveying roller 120. At this time, the plate glass 300 will apply a thrust to the windshield 182 during the conveying process, so that the windshield 182 rotates relative to the limiting rod 181, thereby giving way to the plate glass 300, which also does not affect the continuous annealing of the plate glass 300.

[0106] In this embodiment, there are multiple windshields 182, which are arranged side by side along the first direction, and two adjacent windshields 182 are arranged in close contact, and the multiple windshields 182 can all rotate relative to the limit rod 181. In this way, during the conveying process of the plate glass 300, when the thickness of a certain position of the plate glass 300 in the first direction is greater than the gap between the windshield 182 and the conveying roller 120, only one or more windshields 182 corresponding to the position will rotate relative to the limit rod 181 under the thrust of the plate glass 300, and the remaining windshields 182 will not rotate relative to the limit rod 181, further ensuring the stability of the temperature field in the kiln body 111.

[0107] It should be noted that the fourth drive assembly 183 is installed at the top of the kiln body 111 in the first annealing furnace section 110 and is connected to the lifting rod 184. The lifting rod 184 is arranged parallel to the limit rod 181 and is connected to the limit rod 181 through the connecting block 185.
