[0058] At present, in the production process of float glass and other plate glass, the annealing furnace is an indispensable core device. Its function is 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. However, during 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 furnace may explode, generating a large amount of glass fragments and falling downwards. The current method of cleaning glass fragments is generally to open the annealing furnace and manually clean the glass fragments. However, due to the limited space in the annealing furnace, cleaning is difficult, time-consuming and labor-intensive, with low cleaning efficiency and poor cleaning effect. In addition, the annealing furnace is usually equipped with a heating mechanism configured to control the annealing cooling rate. 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.

[0059] In view of this, it is particularly important to design and manufacture an annealing device and glass production equipment with high cleaning efficiency, good cleaning effect and guaranteed annealing effect, especially in glass annealing.

[0060] The following describes some embodiments of the present disclosure in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0061] 1 to 3 , embodiments of the present disclosure provide a glass production apparatus (not shown) configured to produce plate glass 300. The apparatus automatically cleans and transports glass fragments 400, saving time and effort, achieving high cleaning efficiency and excellent cleaning effects. Furthermore, the apparatus prevents glass fragments 400 from affecting the heating mechanism, ensuring an effective annealing process.

[0062] 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 configured to produce formed plate glass 300 and sequentially feed the resulting multiple high-temperature plate glass 300 into the annealing device 100. The annealing device 100 is configured to continuously anneal the multiple plate glass 300, with high annealing efficiency. The annealing device 100 can control the thermal stress of the plate glass 300 to ensure that the plate glass 300 has appropriate permanent stress and temporary stress, thereby ensuring the product quality of the plate glass 300.

[0063] The annealing apparatus 100 includes a first annealing furnace section 110, a conveyor 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 conveyor 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 spaced below the conveyor roller 120. The conveyor roller 120 is configured to transport high-temperature plate glass 300 into the first annealing furnace section 110. The first heating mechanism 150 is configured to dissipate heat to the plate glass 300 to control the annealing cooling rate of the plate glass 300, thereby achieving precise annealing of the plate glass 300.

[0064] Specifically, during the actual annealing process, due to various reasons such as poor temperature control or a high impurity content in the plate glass 300, the plate glass 300 located on the conveyor roller 120 in the first annealing furnace section 110 may explode, generating a large amount of glass fragments 400 that fall downward. In this embodiment, a slag transport mechanism 130 is disposed between the conveyor roller 120 and the heating mechanism. The slag transport mechanism 130 is configured to receive the glass fragments 400 formed by the plate glass 300 exploding during the annealing process to prevent the glass fragments 400 from falling under the action of gravity onto the first heating mechanism 150 located below the conveyor roller 120, 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 configured to transport the glass fragments 400 out of the first annealing furnace section 110 to achieve automatic cleaning and transportation of the glass fragments 400, saving time and effort, and achieving high cleaning efficiency and good cleaning effect.

[0065] It should be noted that the second heating mechanism 160 is installed within the first annealing furnace section 110 and is spaced above the conveyor roller 120. The second heating mechanism 160 is configured 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 conveyor roller 120 from both the top and bottom sides. The cooling mechanism 170 is installed within the first annealing furnace section 110 and is spaced above the conveyor roller 120. The cooling mechanism 170 is configured to blow ambient air onto the plate glass 300 on the conveyor roller 120 to cool the plate glass 300, thereby also achieving the function of controlling the annealing temperature of the plate glass 300.

[0066] 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.

[0067] Furthermore, a curtain mechanism 180 is installed at the end of the first annealing furnace section 110 and is spaced above the conveyor roller 120. The curtain mechanism 180 is configured to block external air to prevent air from circulating inside and outside the first annealing furnace section 110, thereby ensuring a stable temperature field within the first annealing furnace section 110 and facilitating precision annealing. A temperature sensor 190 is installed in the first annealing furnace section 110 and is configured to detect the internal temperature of the first annealing furnace section 110 to facilitate precise control of the annealing temperature and improve the annealing effect.

[0068] In this embodiment, the conveyor rollers 120 and the slag transport mechanism 130 are arranged in parallel. The conveyor rollers 120 and the slag transport mechanism 130 convey in the same direction, that is, the plate glass 300 and the glass fragments 400 are discharged in the same direction, facilitating installation and maintenance. However, this is not limiting. In other embodiments, the conveyor rollers 120 and the slag transport mechanism 130 convey in opposite directions, that is, the plate glass 300 and the glass fragments 400 are discharged in opposite directions, which also facilitates installation and maintenance.

[0069] The slag transport mechanism 130 includes a frame 131, a first drive assembly 132, a driving wheel 133, a driven wheel 134, a conveyor belt 135, a first load-bearing beam 136, a second load-bearing beam 137, a second drive assembly 138, a pressure-regulating roller 139, a tensioning roller 140, and a guide roller 141. The frame 131 is connected to the first annealing lehr section 110. The first drive assembly 132 is mounted on the frame 131 and connected to the driving wheel 133. The first drive assembly 132 is configured to drive the driving wheel 133 in rotation. The driving wheel 133 is in transmission connection with the conveyor belt 135. That is, the driving wheel 133 is connected to the driven wheel 134 via the conveyor belt 135. The driven wheel 134 is rotatably mounted on the frame 131. During rotation, the driving wheel 133 can drive the driven wheel 134 to rotate relative to the frame 131 via the conveyor belt 135. Specifically, the conveyor belt 135 is annular to facilitate the circular rotation of the conveyor belt 135. The first heating mechanism 150 is arranged in the conveyor belt 135. The first heating mechanism 150 can control the temperature of the plate glass 300 on the conveyor roller 120 through the conveyor belt 135. The conveyor belt 135 can prevent the glass fragments 400 formed by the explosion of the conveyor roller 120 from falling onto the first heating mechanism 150.

[0070] Referring to Figure 4 , it should be noted that the conveyor belt 135 has a transport section 1351 and a return section 1352 disposed relative to each other. The transport section 1351 is spaced above the return section 1352, and both the transport section 1351 and the return section 1352 are located between the driving wheel 133 and the driven wheel 134. The first heating mechanism 150 is disposed between the transport section 1351 and the return section 1352. The conveyor belt 135 in the transport section 1351 can be driven by the driving wheel 133 and the driven wheel 134 to move to the return section 1352, while the conveyor belt 135 in the return section 1352 can be driven by the driving wheel 133 and the driven wheel 134 to move to the transport section 1351. Specifically, the conveyor belt 135 in the transport section 1351 is configured to receive the glass fragments 400 and convey the glass fragments 400 out of the first annealing furnace section 110 , and the conveyor belt 135 in the reset section 1352 is configured to realize the cyclic rotation of the conveyor belt 135 .

[0071] The first annealing lehr section 110 includes a kiln body 111 and a base 112. The base 112 is connected to the bottom of the kiln body 111 and, together with the kiln body 111, forms a bottom cavity 113. The frame 131 is connected to the base 112. The transport section 1351, the conveyor roller 120, and the first heating mechanism 150 are all disposed within the kiln body 111, and the reset section 1352 is disposed within the bottom cavity 113. Specifically, the kiln body 111 has an internal cavity 114, which is independent of the bottom cavity 113. The conveyor belt 135 in the transport section 1351 is disposed within the internal cavity 114, while the conveyor belt 135 in the reset section 1352 is disposed within the bottom cavity 113.

[0072] Specifically, the first load-bearing beam 136 and the second load-bearing beam 137 are both connected to the frame 131; the first load-bearing beam 136 is arranged in the internal cavity 114 and is located below the transport section 1351. The first load-bearing beam 136 is configured to support the conveyor belt 135 located in the transport section 1351 to prevent the conveyor belt 135 from falling downward under the action of gravity, thereby ensuring the stability of the transportation of the glass fragments 400; the second load-bearing beam 137 is arranged in the bottom cavity 113 and is located below the reset section 1352. The second load-bearing beam 137 is configured to support the conveyor belt 135 located in the reset section 1352 to prevent the conveyor belt 135 from falling downward under the action of gravity, thereby ensuring the stability of the reset of the conveyor belt 135.

[0073] Referring to Figure 4 , first drive assembly 132 includes a first drive member 1321 and a gearbox 1322. Gearbox 1322 is mounted on frame 131. The input end of gearbox 1322 is connected to first drive member 1321, and the output end of gearbox 1322 is connected to driving wheel 133. First drive member 1321 is configured to output power to gearbox 1322, which is configured to increase torque, reduce rotational speed, and output power to driving wheel 133. Specifically, first drive member 1321 utilizes variable frequency control, in conjunction with gearbox 1322, to flexibly adjust the rotational speed of driving wheel 133, thereby adjusting the feed speed of conveyor belt 135.

[0074] It is noteworthy that the second drive assembly 138 is mounted on the frame 131 and is in driving connection with the pressure regulating roller 139. The conveyor belt 135 is arranged in close contact with the pressure regulating roller 139. The pressure regulating roller 139 is arranged opposite the driving wheel 133. The conveyor belt 150 is sleeved outside the driving wheel 130 and extends tangentially to the driving wheel 130, so that a portion of the conveyor belt 150 is arranged between the pressure regulating roller 139 and the driving wheel 133. This part of the conveyor belt 150 is pressed against the circumferential surface of the driving wheel 130 by the action of the pressure regulating roller 139. The second driving assembly 138 is configured to drive the pressure regulating roller 139 to move closer to or 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 to ensure that the friction between the conveyor belt 135 and the driving wheel 133 is within a reasonable range, thereby avoiding the friction between the conveyor belt 135 and the driving wheel 133 being too large or too small, thereby avoiding the conveyor belt 135 from tearing, breaking or slipping, and ensuring the conveying efficiency of the glass fragments 400.

[0075] Referring to Figure 5 , the second drive assembly 138 includes a second drive member 1381, a capstan 1382, a fixed pulley 1383, a transmission rope 1384, and a rotating rod 1385. The frame 131 is provided with a support shaft 1311. The rotating rod 1385 is sleeved around the support shaft 1311 and rotatably connected to the support shaft 1311. The rotating rod 1385 is rotatable relative to the support shaft 1311, and the support shaft 1311 supports and limits the rotating rod 1385. Specifically, the second drive member 1381 is mounted on the frame 131 and connected to the capstan 1382. The second drive member 1381 is configured to drive the capstan 1382 to rotate. 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 configured to adjust the movement direction of the transmission rope 1384.

[0076] Furthermore, the support shaft 1311 is arranged in the middle 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. The second driving member 1381 is configured 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.

[0077] 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.

[0078] 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 toward 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, 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, 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.

[0079] 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-adjusting roller 139 approaches or moves 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.

[0080] Referring to Figures 6 and 7 , in this embodiment, the conveyor belt 135 is a mesh belt densely covered with a plurality of mesh holes 1353 to reduce the weight of the entire conveyor belt 135 , thereby achieving lightweightness and facilitating long-distance transport. Furthermore, the conveyor belt 135 with mesh holes 1353 does not affect heat transfer within the first annealing furnace section 110 , thereby ensuring annealing effectiveness. 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 ensures that the glass fragments 400 falling from the conveyor roller 120 are fully received, preventing the glass fragments 400 from being missed.

[0081] 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. The reasonable length and width of the mesh 1353 can ensure the bearing effect of the glass fragments 400 and prevent the glass fragments 400 from falling through the mesh 1353.

[0082] 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, the 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 both 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.

[0083] In this embodiment, the spiral ring 1354 is rectangular, i.e., the mesh 1353 formed by the spiral ring 1354 is rectangular. The cross-section of the spiral ring 1354 is circular, and the diameter of the cross-section of the spiral ring 1354 ranges from 1 mm to 4 mm. The connecting rod 1355 is cylindrical, and the diameter of the connecting rod 1355 ranges from 1.5 mm to 5 mm. A reasonable diameter of the cross-section of the spiral ring 1354 and the connecting rod 1355 can ensure the strength and structural stability of the conveyor belt 135, thereby ensuring the stability of conveying the glass fragments 400.

[0084] In this embodiment, the spiral ring buckle 1354 and the connecting rod 1355 are both made of stainless steel, but are not limited to this. In other embodiments, the spiral ring buckle 1354 and the connecting rod 1355 can both be made of metal materials or both be made of plastic. There is no specific limitation on the material of the spiral ring buckle 1354 and the connecting rod 1355.

[0085] Referring to Figure 8 , it should be noted that the frame 131 is provided with a limiting frame 1313 having a guide rail 1312. The guide rail 1312 extends in the vertical direction. The tensioning roller 140 slidably engages with the guide rail 1312 and is rotatable relative to the guide rail 1312. The conveyor belt 135 is disposed in close contact with the tensioning roller 140 and is disposed at the bottom of the tensioning roller 140. The conveyor belt 135 supports the tensioning roller 140. The weight of the tensioning roller 140 is borne on the conveyor belt 135 to achieve the tensioning function of the conveyor belt 135. The conveyor belt 135 can also 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.

[0086] In this embodiment, the weight of the tensioning roller 140 is borne on the conveyor belt 135 to achieve the tensioning function of the conveyor belt 135. However, this is not limiting. In another embodiment, a counterweight is suspended from the tensioning roller 140. The weight of the counterweight and the tensioning roller 140 is jointly borne on the conveyor belt 135 to further ensure the tension of the conveyor belt 135. In another embodiment, an electric cylinder is mounted on the limit frame 1313 and connected to the tensioning roller 140. The electric cylinder drives the tensioning roller 140 to slide relative to the guide rail 1312 to adjust the tensioning force of the tensioning roller 140 on the conveyor belt 135, ensuring that the conveyor belt 135 is in a tensioned state.

[0087] 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 configured to guide and limit the conveyor belt 135 to prevent the conveyor belt 135 from being offset or tilted.

[0088] 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.

[0089] Referring to Figure 9 , the conveyor roller conveyor 120 includes a third drive 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 rotatably mounted within the first annealing lehr section 110. The plurality of rotating rollers 122 work together to drive the sheet glass 300 forward. The third drive assembly 121 is connected to the plurality of rotating rollers 122 and is configured to simultaneously drive the plurality of rotating rollers 122 to rotate relative to the first annealing lehr section 110. Specifically, a leakage gap 123 is formed between adjacent rotating rollers 122. The leakage gap 123 is configured to allow glass fragments 400 to fall onto the slag transport mechanism 130, preventing the glass fragments 400 from adhering to the rotating rollers 122. The leakage gap 123 is also configured to allow heat to pass through, ensuring accurate temperature control within the first annealing lehr section 110.

[0090] In this embodiment, the plurality of rotating rollers 122 are divided into multiple groups, each group having at least one rotating roller 122. The third drive assembly 121 includes multiple third drive members 1211 and multiple reduction gearboxes 1212. Each third drive member 1211 is connected to a reduction gearbox 1212, and each reduction gearbox 1212 is connected to a group of rotating rollers 122. Each third drive member 1211 is frequency-controlled by a frequency converter to independently control the rotational speed of each group of rotating rollers 122, thereby achieving differentiated rotational speed control and facilitating precise control of the conveying speed of the plate glass 300.

[0091] Referring to Figures 10 and 11 , it is noteworthy that a guide plate 1111 is provided on the inner side of the top wall of the first annealing kiln section 110. Specifically, the guide plate 1111 is disposed within 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 extend along the conveying direction of the conveyor roller 120. The guide holes 1112 are configured to guide the internal air in the internal cavity 114 to define the flow direction of the internal air, avoid turbulence of the internal air, ensure a stable internal temperature field, improve the annealing effect, and facilitate precision annealing.

[0092] For ease of understanding, the arrangement direction of the plurality of guide holes 1112 is referred to as the first direction, i.e., the plurality of guide holes 1112 are arranged parallel and spaced along the first direction. The conveying direction of the conveyor rollers 120 and the slag transport mechanism 130 is referred to as the second direction, with the first direction being perpendicular to the second direction. Furthermore, the sheet glass 300 enters the kiln body 111 of the first annealing lehr section 110 along its length. The length of the sheet glass 300 is referred to as the second direction, and the width of the sheet glass 300 is referred to as the first direction.

[0093] It should be noted that during the annealing process, the internal temperature of the kiln body 111 varies in the second direction, so that the annealing temperature of the plate glass 300 at different locations within the kiln body 111 is different, ensuring the annealing effect. Furthermore, since the annealing temperatures at different locations within the kiln body 111 are different, the air within the kiln body 111 tends 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 within 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 within the annealing kiln shell can be effectively avoided, facilitating precise control of the annealing temperature, and also contributing to energy conservation and improved economic efficiency.

[0094] Furthermore, there are multiple guide plates 1111, and the multiple guide plates 1111 are arranged in parallel and spaced apart along the second direction. The guide holes 1112 on the multiple guide plates 1111 are aligned, so that air at different locations within the kiln body 111 flows from between two adjacent guide plates 1111 into the guide holes 1112, and then flows along the guide holes 1112 toward locations with higher temperatures, thereby ensuring the smoothness and stability of the air flow within the kiln body 111. Specifically, the multiple guide holes 1112 on two adjacent guide plates 1111 are arranged in a one-to-one correspondence, so that 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, resulting in a good guide effect and effectively avoiding the occurrence of turbulent flow.

[0095] In this embodiment, the spacing between any two adjacent guide holes 1112 on the guide plate 1111 is uniform, and the apertures of the multiple guide holes 1112 are the same. Specifically, the spacing between any two adjacent guide holes 1112 ranges from 100 mm to 500 mm. A reasonable spacing between any two adjacent guide holes 1112 ensures that air within the annealing furnace shell can quickly enter the adjacent guide hole 1112 in the first direction, thereby ensuring effective diversion. The apertures of the guide holes 1112 range from 100 mm to 300 mm. A reasonable aperture of the guide holes 1112 can minimize air flow velocity while ensuring effective diversion, thereby facilitating precise control of the annealing temperature.

[0096] It is noteworthy that the processed sheet glass 300 is thinner in the middle and thicker at the edges in the first direction, resulting in a faster heat dissipation rate in the middle of the sheet glass 300 and a slower heat dissipation rate at the edges. After the conveyor rollers 120 deliver the processed sheet glass 300 into the kiln body 111, in the first direction, the air temperature in the middle of the sheet glass 300 is higher, the molecular activity is higher, the air flow rate is faster, and the air flow rate is larger. However, the air temperature in the locations corresponding to the edges of the sheet glass 300 is lower, the molecular activity is lower, the air flow rate is slower, and the air flow rate is smaller.

[0097] 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.

[0098] In another embodiment, the aperture of the guide hole 1112 first increases and then decreases in the 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 the air with a larger flow rate at the corresponding position in the middle of the plate glass 300, and the guide holes 1112 with a smaller aperture on both sides of the guide plate 1111 can guide the air with a smaller flow rate at the corresponding positions on both sides of the plate glass 300, which can also ensure the diversion effect.

[0099] 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 configured 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 during the process of the air flowing 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.

[0100] In this embodiment, an exhaust pipe 1114 is connected to the exhaust port 1113, and the air in the internal cavity 114 can be discharged to the outside through the exhaust port 1113 and the exhaust pipe 1114. Specifically, the exhaust pipe 1114 is provided with an air flow control valve 1115, which is configured to adjust the flow rate of the air discharged to the outside, thereby adjusting the pressure relief rate and improving the accuracy of temperature control.

[0101] Furthermore, the spacing between adjacent guide plates 1111 ranges from 200 mm to 800 mm. This reasonable spacing facilitates the creation of exhaust port 1113 and the installation of exhaust pipe 1114. Exhaust pipe 1114 and exhaust port 1113 have the same diameter, ranging from 200 mm to 500 mm. This reasonable diameter allows for adjustment of the exhaust flow rate over a wide range, further improving the accuracy of temperature control.

[0102] In this embodiment, there are multiple exhaust ports 1113 and exhaust pipes 1114, and the multiple exhaust ports 1113 are arranged at intervals along the first direction. Each exhaust port 1113 is connected to an exhaust pipe 1114, and each exhaust pipe 1114 is provided with an air volume regulating valve 1115. By adjusting the exhaust flow of each air volume regulating valve 1115, the internal cavity 114 can be exhausted in a zoned manner, thereby achieving overall precise control of the annealing temperature.

[0103] Referring to Figure 12 , the first heating mechanism 150 includes a fixed frame 151 and an electric heater 152. The electric heater 152 is mounted within the fixed frame 151. The fixed frame 151 is connected to the kiln body 111 of the first annealing furnace section 110 and is disposed parallel to and spaced from the bottom of the conveyor roller 120. The fixed frame 151 is configured to support and secure the electric heater 152. The electric heater 152 is configured to dissipate heat when powered on to regulate the annealing cooling rate of the plate glass 300.

[0104] Furthermore, multiple electric heating elements 152 are provided, extending along the conveying direction of the conveyor roller 120. The multiple electric heating elements 152 are arranged in parallel and spaced apart within the fixed frame 151. That is, the multiple electric heating elements 152 are arranged in parallel and spaced apart along a first direction, and the direction in which the electric heating elements 152 extend is a second direction. The multiple electric heating elements 152 work together to enhance heat dissipation and ensure an effective annealing process.

[0105] It is worth noting that since the plate glass 300 formed during 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 rate on both sides of the plate glass 300 from being too fast, it is necessary to control the annealing cooling temperature in the middle of the plate glass 300 to be lower than the annealing cooling temperature on both sides of the plate glass 300.

[0106] In this embodiment, the spacing between adjacent electric heating elements 152 is equal or gradually increases from the edge to the center of the conveyor roller 120. That is, in the first direction, the number of electric heating elements 152 corresponding to the center of the sheet glass 300 is relatively small and sparsely distributed, while the number of electric heating elements 152 corresponding to the edges of the sheet glass 300 is relatively large and densely distributed. In this way, the multiple electric heating elements 152 work together to provide less heat to the center of the sheet glass 300 and more heat to the edges of the sheet glass 300, ensuring that the annealing and cooling temperature of the center of the sheet glass 300 is lower than the annealing and cooling temperatures at the edges of the sheet glass 300.

[0107] 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.

[0108] The electric heating element 152 includes an insulating column 1521 and a resistance wire 1522. The insulating column 1521 is mounted within the fixed frame 151. The insulating column 1521 extends in the second direction. The fixed frame 151 is configured 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 configured to dissipate heat when energized to control the annealing cooling rate of the plate glass 300.

[0109] In this embodiment, the specific structure of the second heating mechanism 160 is the same as that of the first heating mechanism 150 , and will not be described in detail herein.

[0110] Referring to Figure 13 , the cooling mechanism 170 includes a fan 171, a bellows 172, and an air inlet pipe 173. The bellows 172 are installed within the kiln body 111 of the first annealing lehr section 110 and are spaced apart above the conveyor roller 120. One end of the fan 171 is connected to the outside world, and the other end is connected to the bellows 172. Ventilation holes 1721 are provided at the bottom of the bellows 172, and the positions of the vents 1721 correspond to the positions of the conveyor roller 120. The fan 171 is configured to generate negative pressure to draw outside air into the bellows 172. The air is then blown toward the sheet glass 300 on the conveyor roller 120 through the vents 1721 at the bottom of the bellows 172, thereby cooling the sheet glass 300 and regulating the annealing cooling rate of the sheet glass 300.

[0111] Furthermore, an air intake pipe 173 is connected between the fan 171 and the wind box 172. The outside air drawn in by the fan 171 can enter the wind box 172 through the air intake pipe 173 and be blown into the internal cavity 114 of the kiln body 111 through the ventilation holes 1721. Specifically, the air intake pipe 173 is provided with an air volume regulating valve 174. The air volume regulating valve 174 is configured to adjust the flow rate of outside air entering the internal cavity 114, thereby adjusting the air volume for cooling the plate glass 300 and improving the accuracy of temperature control.

[0112] 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 all connected to the bellows 172. Each air inlet pipe 173 is provided with an air volume regulating valve 174. By adjusting the air flow rate 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.

[0113] It is worth noting that during the annealing process, the plate glass 300 is continuously fed forward along the second direction driven by the conveyor 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.

[0114] In this embodiment, a plurality of ventilation holes 1721 are arranged in a rectangular array. These ventilation holes 1721 work together to increase airflow and enhance the cooling effect. Specifically, the density of the ventilation holes 1721 is uniform or gradually increases along the conveying direction of the conveyor roller 120. That is, the density of the ventilation holes 1721 is uniform or gradually increases along the second direction. This gradually enhances the cooling effect on the sheet glass 300 in the second direction, ensuring that the annealing temperature of the sheet glass 300 continues to decrease in the second direction.

[0115] Referring to Figure 14 , the curtain mechanism 180 includes a limiting rod 181, a windshield 182, a fourth drive assembly 183, and a lifting rod 184. The limiting rod 181 is disposed at the end of the kiln body 111 within the first annealing furnace section 110 and is spaced apart above the conveyor roller 120. The limiting rod 181 extends perpendicular to the conveying direction of the conveyor roller 120, i.e., the limiting rod 181 extends along a first direction. Specifically, the windshield 182 is provided with a sleeve 1821 that is sleeved around the limiting rod 181 and is rotatable relative to the limiting rod 181. The windshield 182 is configured to block airflow to prevent outside air from flowing into the kiln body 111 and to prevent air from flowing out of the kiln body 111. This prevents air from circulating between the inside and outside of the kiln body 111 of the first annealing furnace section 110, thereby ensuring a stable temperature field within the kiln body 111, ensuring annealing results, and facilitating precision annealing.

[0116] Furthermore, the end of the windshield 182 that is distal from the limiting rod 181 is spaced apart from the conveyor roller 120, and the gap between the windshield 182 and the conveyor roller 120 is greater than the thickness of the sheet glass 300. During the conveyor roller 120's conveying of the sheet glass 300, the windshield 182 does not interfere with the sheet glass 300, meaning that the windshield 182 does not affect the continuous annealing of the sheet glass 300. However, in certain scenarios, if the thickness of a certain location of the sheet glass 300 is greater than the gap between the windshield 182 and the conveyor roller 120, the sheet glass 300 will exert a thrust on the windshield 182 during conveyance, causing it to rotate relative to the limiting rod 181, thereby clearing the sheet glass 300. This similarly does not affect the continuous annealing of the sheet glass 300.

[0117] In this embodiment, a plurality of windshields 182 are arranged side by side along the first direction, with adjacent windshields 182 positioned close together. Each of the plurality of windshields 182 is capable of rotating relative to the limiting rod 181. Thus, during the conveyance 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 conveyor roller 120, only the one or more windshields 182 corresponding to that position will rotate relative to the limiting rod 181 under the thrust of the plate glass 300. The remaining windshields 182 will not rotate relative to the limiting rod 181, thereby further ensuring a stable temperature field within the kiln body 111.

[0118] 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.
