Description

Technical Field

[0001] This application relates to the field of flip-type glass tunnel furnaces, and in particular to a flip-type glass tunnel furnace. Background Technology

[0002] In related technologies, glass tunnel furnaces are used to dry ink on glass plates. Multiple glass plates are placed flat one by one inside the glass tunnel furnace. A conveying mechanism inside the glass tunnel furnace transports the glass plates from the feed end to the discharge end of the glass tunnel furnace. A drying mechanism inside the glass tunnel furnace dries the ink on the glass plates.

[0003] However, when the width and length of the glass plates are large, in order for the glass tunnel furnace to dry a preset number of glass plates at the same time, both the width and length of the glass tunnel furnace need to be increased. The large footprint of the glass tunnel furnace leads to the need for a larger factory building to house the glass tunnel furnace, and increases the manufacturing cost of the glass tunnel furnace, as well as the production cost of the glass plates. Summary of the Invention

[0004] In order to reduce the footprint of glass tunnel furnaces, lower the manufacturing cost of glass tunnel furnaces, and reduce the production cost of glass sheets, this application provides a flip-type glass tunnel furnace.

[0005] The technical solution for a flip-type glass tunnel furnace provided in this application is as follows:

[0006] A flip-type glass tunnel furnace includes: a furnace body defining a drying channel; a feed inlet and a discharge outlet opposite to each other and spaced apart along a first direction of the furnace body; the feed inlet and the discharge outlet both communicating with the drying channel; a glass plate entering the furnace body through the feed inlet and leaving the furnace body through the discharge outlet.

[0007] Multiple conveying units are movably arranged within the furnace body at intervals along the circumferential direction. Each conveying unit includes a plate frame and a support rod. The support rod is inclinedly arranged on the top wall of the plate frame, and the glass plate is supported on the top wall of the plate frame. A driving assembly is disposed within the furnace body and is pulsatorically connected to the plate frame of each conveying unit. The driving assembly is used to drive the plate frame to circulate between the feed inlet and the discharge outlet along the circumferential direction of the furnace body. A first hot air assembly is disposed within the furnace body and is used to blow hot air into the furnace body.

[0008] By adopting the above technical solution, the glass plates are placed vertically and inclined on the top wall of the plate frame by support rods. The side walls of the glass plates are supported by the support rods, and the bottom walls are supported by the plate frame. The drive assembly drives multiple plate frames to circulate between the inlet and outlet along the circumference of the furnace body. Compared with the prior art, when the length and width of the glass plates are both large, the flip-type glass tunnel furnace can simultaneously dry a preset number of glass plates in a smaller volume, thereby reducing the floor space required for the flip-type glass tunnel furnace, lowering its manufacturing cost, and consequently reducing the production cost of the glass plates.

[0009] Preferably, the drive assembly includes a drive member, a drive wheel assembly, a driven wheel assembly, and a transmission chain. The drive member is disposed inside the furnace body. The drive wheel assembly and the driven wheel assembly are both pivotally mounted inside the furnace body. The transmission chain is wound around the outside of the drive wheel assembly and the outside of the driven wheel assembly, and the transmission chain is drively connected to both the drive wheel assembly and the driven wheel assembly. The transmission chain is connected and cooperates with the plate frame of each conveying unit. The drive member is connected and cooperates with the drive wheel assembly. The drive member is used to drive the drive wheel assembly to drive the transmission chain to rotate, so that the transmission chain drives the plate frame to circulate along the circumference of the furnace body.

[0010] By adopting the above technical solution, when an undried glass plate is placed on the plate rack, the drive unit drives the plate rack to move from the feed port to the discharge port through the transmission chain. When the plate rack moves to the discharge port, the dried glass plate on the plate rack is transferred to the outside of the furnace body. Then, the drive unit drives the plate rack to rotate downward around the central axis of the drive wheel set along the outside of the drive wheel set through the transmission chain. Then, the drive unit drives the plate rack to move from the discharge port to the feed port through the transmission chain, thereby achieving the technical effect of transporting glass plates with the plate rack.

[0011] Preferably, the conveying unit further includes a limiting member, which is disposed on the top wall of the plate frame. The top wall of the limiting member is provided with a limiting protrusion. Along the first direction of the furnace body, the limiting protrusion is spaced apart from the support rod. The glass plate is inserted between the limiting protrusion and the support rod, and the glass plate is limited and engaged with the limiting protrusion.

[0012] By adopting the above technical solution, when the glass plate is placed on the plate frame, the lower end of the glass plate is inserted into the limiting protrusion and cooperates with the limiting protrusion to limit it, thereby achieving the technical effect of limiting the glass plate on the plate frame. This can prevent the glass plate from detaching from the plate frame and falling into the furnace body, causing the glass plate to break, and thus improve the working reliability of the flip-type glass tunnel furnace.

[0013] Preferably, along a first direction of the furnace body, the furnace body includes a heating section and a cooling section. The heating section is located between the feed inlet and the discharge outlet, and the cooling section is located on the side of the heating section near the discharge outlet. The first hot air assembly is disposed opposite to the heating section. The flip-type glass tunnel furnace also includes a cold air assembly, which is disposed in the furnace body and opposite to the cooling section. The cold air assembly is used to blow cold air into the furnace body.

[0014] The furnace body includes an outer shell and an inner shell. The outer shell is fitted over the outer side of the inner shell, and the inner shell defines the drying channel. Multiple conveying units are movably disposed within the inner shell. A first air supply channel and a first air inlet channel are defined between the outer shell and the inner shell in the heating section. The first air inlet channel and the first air supply channel are spaced apart and communicate with the external environment. The first air supply channel communicates with the drying channel. The first hot air assembly includes a first fan and a first heating element. The first fan is disposed in the furnace body. The air inlet end of the first fan communicates with the first air inlet channel, and the air outlet end of the first fan communicates with the first air supply channel. The first heating element is disposed within the first air supply channel and is opposite to the air outlet end of the first fan. The first fan is used to transport the gas in the first air inlet channel to the drying channel.

[0015] By adopting the above technical solution, the first fan draws the gas in the first air inlet channel into the first air delivery channel. When the gas enters the first air delivery channel through the air outlet of the first fan, the gas is heated to a preset temperature by the first heating element. The gas heated to the preset temperature flows into the drying channel, thereby achieving the technical effect of the first hot air assembly blowing hot air into the drying channel.

[0016] Preferably, along the second direction of the furnace body, the inner shell of the heating section has a first wall surface and a second wall surface that are opposite to each other and spaced apart. The first wall surface is provided with an air inlet hole, and the second wall surface is provided with an air outlet hole. The first air supply channel communicates with the air inlet hole and the first air inlet channel communicates with the air outlet hole. The first hot air assembly further includes a second heating element, which is disposed in the first air inlet channel and is opposite to the air inlet end of the first fan.

[0017] The outer shell of the heating section is provided with a first connecting hole, which is connected to the first air inlet channel and the external environment. The first connecting hole is provided with a first throttle valve, which is used to adjust the gas flow rate in the first connecting hole.

[0018] By adopting the above technical solution, as the temperature inside the furnace gradually rises to the preset temperature, the first throttling valve gradually closes, thereby controlling the amount of gas drawn from the external environment by the first blower. This prevents ambient temperature gas from entering the first air inlet channel and mixing with the gas in the first air inlet channel, which would lower the gas temperature in the first air inlet channel. This reduces the time required to raise the temperature inside the furnace to the preset temperature. Furthermore, when the temperature inside the furnace reaches the preset temperature, the first throttling valve closes completely, the first blower draws gas from the drying channel into the first air inlet channel, the second heating element heats the gas in the first air inlet channel, and then the first blower re-transports the gas from the first air inlet channel back into the drying channel. This achieves gas circulation inside the furnace, eliminating the need for the first and second heating elements to heat the gas in the external environment, thus reducing their energy consumption and consequently lowering the energy consumption of the flip-type glass tunnel furnace.

[0019] Preferably, the outer casing of the heating section is provided with a second connecting hole, which communicates with the first air inlet channel. The outer casing of the heating section is provided with a third connecting hole, which is located on the side of the heating section near the cooling section. The third connecting hole communicates with both the second connecting hole and the drying channel. The second connecting hole is provided with a second throttle valve, which is used to adjust the gas flow rate in the second connecting hole.

[0020] By adopting the above technical solution, after the temperature inside the furnace body rises to the preset temperature, the first throttle valve closes and the second throttle valve opens. The first fan draws gas from the tail of the heating section through the second and third connecting holes. The gas at the tail of the heating section is reheated by the first and second heating elements and then transported back to the drying channel by the first fan. This achieves the technical effect of recycling the gas at the tail of the heating section and reduces the energy consumption of the flip-type glass tunnel furnace.

[0021] Preferably, the cold air assembly includes a second fan and a cooling fin assembly. The second fan is disposed in the furnace body, and the air inlet of the second fan is connected to the drying channel. An installation space is defined between the outer shell and the inner shell of the cooling section. The outer shell is provided with a fourth connecting hole, and the inner shell is provided with a fifth connecting hole. Both the fourth and fifth connecting holes are connected to the installation space. The cooling fin assembly is disposed in the installation space and is opposite to the fifth connecting hole. Cooling liquid flows through the cooling fin assembly, and the cooling fin assembly is used to cool gas. The second fan is used to draw gas from the drying channel.

[0022] By adopting the above technical solution, firstly, the second fan draws gas from the external environment into the drying channel through the fourth and fifth connecting holes. Then, the second fan draws gas from the drying channel into the external environment. As the gas from the external environment enters the drying channel through the fourth and fifth connecting holes, the gas passes through the cooling fin assembly and exchanges heat with the cooling fin assembly. The cooling fin assembly cools the gas to a preset temperature. Then, the cooled gas enters the drying channel to cool the glass plate, thereby achieving the technical effect of the cold air assembly cooling the glass plate.

[0023] Preferably, the cooling air assembly further includes a third fan, which is disposed within the installation space and located between the cooling fin assembly and the inner shell. The air inlet of the third fan is opposite to the cooling fin assembly, and the air outlet of the third fan is opposite to the fifth connecting hole.

[0024] By adopting the above technical solution, the third fan can assist the second fan in drawing gas from the external environment into the drying channel. This can minimize the decrease in suction power of the second fan within the installation space, thus preventing insufficient suction power and ensuring that the second fan can draw enough gas into the drying channel. This can prevent the glass plate from failing to cool to the preset temperature, thereby improving the operational reliability of the flip-type glass tunnel furnace.

[0025] Preferably, along the first direction of the furnace body, the furnace body further includes a preheating section, the preheating section being located on the side of the heating section near the feed inlet, a second air supply channel and a second air inlet channel defining a spaced-apart space between the outer shell and the inner shell of the preheating section, the second air inlet channel and the second air supply channel being connected to the external environment, and the second air supply channel being connected to the drying channel.

[0026] The flip-type glass tunnel furnace further includes a second hot air assembly, which includes a fourth fan and a third heating element. The fourth fan is located in the furnace body, with its inlet end connected to the second air inlet channel and its outlet end connected to the second air supply channel. The third heating element is located in the second air supply channel and is opposite to the outlet end of the fourth fan. The fourth fan is used to transport the gas in the second air supply channel to the drying channel. The temperature of the gas blown into the drying channel by the second hot air assembly is lower than the temperature of the gas blown into the drying channel by the first hot air assembly.

[0027] By adopting the above technical solution, the fourth fan in the preheating section draws gas from the external environment into the drying channel. When the gas from the external environment flows into the second air supply channel, the third heating element heats the gas in the second air supply channel. The temperature of the gas in the second air supply channel is lower than that of the gas in the first air supply channel. This achieves the technical effect of preheating the glass plate and gradually drying the ink on the glass plate. It avoids direct contact between the ink and the high-temperature gas, prevents the ink from expanding and deforming, and improves the operational reliability of the flip-type glass tunnel furnace.

[0028] Preferably, the flip-type glass tunnel furnace further includes: a fifth fan, which is disposed in the furnace body and located on the side of the preheating section near the feed inlet. The air inlet of the fifth fan is connected to the drying channel, and the fifth fan is used to draw gas from the drying channel to regulate the temperature in the drying channel.

[0029] By adopting the above technical solution, the fifth fan draws the gas in the drying channel to the external environment, thereby preventing the continuous accumulation of high-temperature gas in the drying channel and avoiding the temperature in the drying channel from exceeding the preset temperature. This achieves the technical effect of regulating the temperature in the drying channel to maintain the temperature in the drying channel at the preset temperature.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. A glass plate is placed vertically and inclined on the top wall of a plate rack via support rods. The side walls of the glass plate are supported by the support rods, and the bottom wall is supported by the plate rack. A drive assembly drives multiple plate racks to circulate between the inlet and outlet along the circumference of the furnace body. Compared with existing technologies, when the length and width of the glass plate are both large, the flip-type glass tunnel furnace can simultaneously dry a preset number of glass plates within a smaller volume, thereby reducing the floor space required and the manufacturing cost of the flip-type glass tunnel furnace, and consequently reducing the production cost of the glass plate.

[0032] 2. The third fan can assist the second fan in drawing gas from the external environment into the drying channel, thereby minimizing the decrease in suction power of the second fan within the installation space, which would result in insufficient suction power and the second fan being unable to draw enough gas into the drying channel. This would prevent the glass plate from failing to cool to the preset temperature, thus improving the operational reliability of the flip-type glass tunnel furnace.

[0033] 3. The fifth fan draws the gas in the drying channel to the external environment, thereby preventing the continuous accumulation of high-temperature gas in the drying channel and avoiding the temperature in the drying channel from exceeding the preset temperature. This achieves the technical effect of regulating the temperature in the drying channel to maintain the temperature in the drying channel at the preset temperature. Attached Figure Description

[0059] The following is in conjunction with the appendix Figures 1-16 This application will be described in further detail.

[0060] This application discloses a flip-type glass tunnel furnace 100.

[0061] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The flip-type glass tunnel furnace 100 according to an embodiment of this application includes: a furnace body 1, multiple conveying units 2, a drive assembly 3, and a first hot air assembly 4. The furnace body 1 defines a drying channel 11, and along a first direction of the furnace body 1, the first direction of the furnace body 1 can point to... Figure 1 In the left and right directions, the side wall of the furnace body 1 is provided with opposite and spaced-apart feed inlets 12 and discharge outlets 13. Specifically, the left side wall of the furnace body 1 is provided with feed inlet 12 and the right side wall of the furnace body 1 is provided with discharge outlet 13. Both feed inlet 12 and discharge outlet 13 are connected to the drying channel 11. The glass plate 8 enters the furnace body 1 through feed inlet 12 and leaves the furnace body 1 through discharge outlet 13.

[0062] Multiple conveying units 2 are movably arranged in the furnace body 1 at intervals along the circumference of the furnace body 1. Each conveying unit 2 includes a plate frame 21 and a support rod 22. The support rod 22 is inclinedly arranged on the top wall of the plate frame 21, and the glass plate 8 is supported on the top wall of the plate frame 21.

[0063] Specifically, after the glass plate 8 enters the furnace body 1 through the feed inlet 12, along the height direction of the furnace body 1, the height direction of the furnace body 1 can be pointed to... Figure 1 In the vertical direction, the glass plate 8 is placed at an angle on the upper wall of the frame 21, and the glass plate 8 is engaged with the support rod 22. The side wall of the glass plate 8 is supported by the support rod 22, and the lower wall of the glass plate 8 is supported by the frame 21. In other words, the glass plate 8 is placed on the frame 21 in a vertically inclined manner.

[0064] In some specific embodiments, the support rod 22 can be tilted to the right on the top wall of the plate frame 21, while in other specific embodiments, the support rod 22 can be tilted to the left on the top wall of the plate frame 21.

[0065] Furthermore, the flip-type glass tunnel furnace 100 may also include a first robotic arm and a second robotic arm. The first robotic arm is disposed inside the furnace body 1 and near the feed inlet 12. The first robotic arm is used to transfer the glass plate 8 located at the feed inlet 12 to the plate holder 21. The second robotic arm is disposed inside the furnace body 1 and near the discharge outlet 13. The second robotic arm is used to transfer the glass plate 8 on the plate holder 21 to the outside of the furnace body 1.

[0066] Furthermore, there are multiple support rods 22, which are arranged sequentially along the second direction of the furnace body 1. The second direction of the furnace body 1 can refer to... Figure 1 In the front-to-back direction, the glass plate 8 is supported by multiple support rods 22.

[0067] The drive assembly 3 is installed inside the furnace body 1. The drive assembly 3 is connected to the plate frame 21 of each conveying unit 2. The drive assembly 3 is used to drive the plate frame 21 to circulate between the feed inlet 12 and the discharge outlet 13 along the circumferential direction of the furnace body 1. The first hot air assembly 4 is installed in the furnace body 1 and is located between the feed inlet 12 and the discharge outlet 13. The first hot air assembly 4 is used to blow hot air into the furnace body 1.

[0068] Specifically, after the glass plate 8 is placed on the plate holder 21, the drive assembly 3 drives the plate holder 21 to move the glass plate 8 from the feed port 12 to the discharge port 13. During the process of the plate holder 21 moving the glass plate 8 from the feed port 12 to the discharge port 13, the first hot air assembly 4 blows hot air into the furnace body 1. The hot air is used to dry the ink on the glass plate 8.

[0069] When the plate frame 21 moves to the discharge port 13, the dried glass plate 8 on the plate frame 21 is transferred to the outside of the furnace body 1, and then the drive assembly 3 drives the plate frame 21 from the discharge port 13 to the feed port 12.

[0070] It should be noted that the movement trajectory of the plate frame 21 is divided into a first movement segment and a second movement segment. The plate frame 21 moving in the first movement segment is located above the plate frame 21 moving in the second movement segment. When the plate frame 21 is filled with glass plate 8, the plate frame 21 moves from the feed inlet 12 to the discharge outlet 13 along the first movement segment. When the dried glass plate 8 on the plate frame 21 is transferred to the outside of the furnace body 1, the plate frame 21 moves from the discharge outlet 13 to the feed inlet 12 along the second movement segment.

[0071] Thus, with the support rod 22 inclinedly mounted on the top wall of the plate holder 21, the glass plate 8 is placed on the top wall of the plate holder 21 in a vertically inclined manner. The side walls of the glass plate 8 are supported by the support rod 22, and the bottom wall of the glass plate 8 is supported by the plate holder 21. The drive assembly 3 drives multiple plate holders 21 to circulate between the feed inlet 12 and the discharge outlet 13 along the circumference of the furnace body 1. Compared with the prior art, when the length and width dimensions of the glass plate 8 are both large, the flip-type glass tunnel furnace 100 can simultaneously dry a preset number of glass plates 8 in a smaller volume size, thereby reducing the floor space of the flip-type glass tunnel furnace 100, reducing the manufacturing cost of the flip-type glass tunnel furnace 100, and consequently reducing the production cost of the glass plate 8.

[0072] Reference Figures 2-4In some embodiments of this application, the drive assembly 3 includes a drive member 31, a drive wheel set 32, a driven wheel set 33, and a transmission chain 34. The drive member 31 is disposed inside the furnace body 1. In some specific embodiments, the drive member 31 may be disposed on the inner side wall of the furnace body 1. The drive wheel set 32 ​​and the driven wheel set 33 are both pivotally mounted inside the furnace body 1. Specifically, one of the drive wheel set 32 ​​and the driven wheel set 33 is disposed near the feed inlet 12, and the other of the drive wheel set 32 ​​and the driven wheel set 33 is disposed near the discharge outlet 13. The drive wheel set 32 ​​and the drive member 31 are disposed opposite each other. In some specific embodiments, the drive wheel set 32 ​​is disposed near the discharge outlet 13, and the driven wheel set 33 is disposed near the feed inlet 12.

[0073] It should be noted that the driving wheel assembly 32 includes two driving wheels, and the driven wheel assembly 33 includes two driven wheels. The two driving wheels are connected by a drive shaft, and the two driven wheels are connected by a drive shaft. The multiple plate frames 21 are located between the two driving wheels and between the two driven wheels.

[0074] Furthermore, the transmission chain 34 is wound around the outside of the driving wheel set 32 ​​and the outside of the driven wheel set 33, and the transmission chain 34 is connected to both the driving wheel set 32 ​​and the driven wheel set 33. The transmission chain 34 is also connected to the plate frame 21 of each conveying unit 2.

[0075] In some specific embodiments, there are two transmission chains 34, namely the first transmission chain 34 and the second transmission chain 34. The driving wheel set 32 ​​includes two driving wheels, namely the first driving wheel and the second driving wheel. The driven wheel set 33 includes two driven wheels, namely the first driven wheel and the second driven wheel.

[0076] Along the second direction of the furnace body 1, the first driving wheel and the first driven wheel are both located in front of the plate frame 21 and are arranged opposite to each other. The second driving wheel and the second driven wheel are both located behind the plate frame 21 and are arranged opposite to each other. The first transmission chain 34 is wound around the outside of the first driving wheel and the outside of the first driven wheel. The second transmission chain 34 is wound around the outside of the second driving wheel and the outside of the second driven wheel. The first transmission chain 34 and the second transmission chain 34 are both connected and cooperate with the plate frame 21.

[0077] The drive component 31 is connected and cooperates with the drive wheel set 32. Specifically, the drive component 31 is connected and cooperates with one of the two drive wheels. The drive component 31 is used to drive the drive wheel set 32 ​​to drive the transmission chain 34 to rotate, so that the transmission chain 34 drives the plate frame 21 to circulate along the circumference of the furnace body 1.

[0078] When an undried glass plate 8 is placed on the plate holder 21, the drive unit 31 drives the plate holder 21 to move from the feed port 12 to the discharge port 13 via the transmission chain 34. When the plate holder 21 moves to the discharge port 13, the dried glass plate 8 on the plate holder 21 is transferred to the outside of the furnace body 1. Along the height direction of the furnace body 1, the drive unit 31 drives the plate holder 21 to rotate downward around the central axis of the drive wheel set 32 ​​along the outside of the drive wheel set 32 ​​via the transmission chain 34. Then, the drive unit 31 drives the plate holder 21 to move from the discharge port 13 to the feed port 12 via the transmission chain 34, thereby achieving the technical effect of the plate holder 21 transporting the glass plate 8.

[0079] In some specific embodiments, the drive element 31 can be a motor, but this application is not limited to this; the drive element 31 can also be a hydraulic motor, etc.

[0080] Reference Figure 3 , Figure 5 and Figure 6 In some embodiments of this application, the conveying unit 2 may further include a limiting member 23, which is disposed on the top wall of the plate frame 21. The top wall of the limiting member 23 is provided with a limiting protrusion 231. Along the first direction of the furnace body 1, the limiting protrusion 231 is spaced apart from the support rod 22. The glass plate 8 is inserted between the limiting protrusion 231 and the support rod 22, and the glass plate 8 is limited and engaged with the limiting protrusion 231.

[0081] Specifically, when the glass plate 8 is placed on the plate frame 21, the lower end of the glass plate 8 is inserted between the limiting protrusion 231 and the support rod 22. The glass plate 8 is in a limiting fit with the support and the limiting protrusion 231, thereby achieving the technical effect of limiting the glass plate 8 on the plate frame 21. This can prevent the glass plate 8 from detaching from the plate frame 21 and falling into the furnace body 1, causing the glass plate 8 to break. This can improve the working reliability of the flip-type glass tunnel furnace 100.

[0082] Furthermore, there are multiple limiting members 23, which are spaced apart along the second direction of the furnace body 1. The limiting protrusion 231 on each limiting member 23 is matched with the lower end of the glass plate 8.

[0083] Furthermore, silicone protective sleeves are provided on the outer side of the support rod 22 and the outer side of the limiting member 23. The silicone protective sleeves can prevent the glass plate 8 from colliding with the limiting member 23 and the support rod 22, and can prevent the glass plate 8 from having appearance defects such as scratches and cracks.

[0084] Reference Figure 1 , Figure 7 and Figure 10In some embodiments of this application, along the first direction of the furnace body 1, the furnace body 1 includes a heating section 14 and a cooling section 15. The heating section 14 is located between the feed inlet 12 and the discharge outlet 13, and the cooling section 15 is located on the side of the heating section 14 near the discharge outlet 13. The first hot air assembly 4 is disposed opposite to the heating section 14. The flip-type glass tunnel furnace 100 also includes a cold air assembly 5. The cold air assembly 5 is disposed in the furnace body 1 and is disposed opposite to the cooling section 15. The cold air assembly 5 is used to blow cold air into the furnace body 1.

[0085] Specifically, during the process of the plate rack 21 transferring the undried glass plate 8 from the feed port 12 to the discharge port 13, the undried glass plate 8 first passes through the heating section 14 and then through the cooling section 15. In the heating section 14, the first hot air assembly 4 blows hot air onto the glass plate 8 to dry the ink on the glass plate 8. In the cooling section 15, the cold air assembly 5 blows cold air onto the glass plate 8 to cool the glass plate 8. When the glass plate 8 is transferred to the outside of the furnace body 1, the glass plate 8 can be directly processed in the next process, thereby saving the natural cooling time of the glass plate 8 and thus improving the production efficiency of the glass plate 8.

[0086] The furnace body 1 includes an outer shell 16 and an inner shell 17. The outer shell 16 is fitted over the outer side of the inner shell 17, and the inner shell 17 defines a drying channel 11. Multiple conveying units 2 are movably disposed within the inner shell 17. A first air supply channel 141 and a first air inlet channel 142 are defined between the outer shell 16 and the inner shell 17 of the heating section 14. The first air inlet channel 142 and the first air supply channel 141 are spaced apart and communicate with the external environment. Gas from the external environment enters between the outer shell 16 and the inner shell 17 through the first air inlet channel 142. The first air supply channel 141 communicates with the drying channel 11. In some specific embodiments, along the second direction of the furnace body 1, the first air inlet channel 142 is disposed near the rear end of the furnace body 1, and the first air supply channel 141 is disposed near the front end of the furnace body 1.

[0087] The first hot air assembly 4 includes a first fan 41 and a first heating element 42. The first fan 41 is disposed on the outer shell 16 of the furnace body 1. The air inlet and air outlet of the first fan 41 extend into the space between the outer shell 16 and the inner shell 17. The air inlet of the first fan 41 is connected to the first air inlet channel 142, and the air outlet of the first fan 41 is connected to the first air supply channel 141. The first heating element 42 is disposed in the first air supply channel 141 and is opposite to the air outlet of the first fan 41. In some specific embodiments, the first heating element 42 can be connected and cooperated with the outer top wall of the inner shell 17. In other specific embodiments, the first heating element 42 can be connected and cooperated with the inner peripheral wall of the outer shell 16. The first fan 41 is used to transport the gas in the first air inlet channel 142 to the drying channel 11.

[0088] Specifically, the first fan 41 draws the gas in the first air inlet channel 142 into the first air delivery channel 141. When the gas enters the first air delivery channel 141 through the air outlet of the first fan 41, the gas is heated to a preset temperature by the first heating element 42. The gas heated to the preset temperature flows into the drying channel 11, thereby achieving the technical effect of the first hot air assembly 4 blowing hot air into the drying channel 11.

[0089] In some specific embodiments, the first fan 41 can be a long-shaft fan, etc., and the first heating element 42 can be a ceramic heating element, etc.

[0090] Furthermore, there can be multiple heating units 14 and multiple first hot air components 4. Multiple heating units 14 and multiple first hot air components 4 are arranged sequentially along the first direction of the furnace body 1, and multiple heating units 14 and multiple first hot air components 4 are arranged in a one-to-one correspondence. This arrangement can extend the drying time of the glass plate 8 in the flip-type glass tunnel furnace 100 so that the ink on the glass plate 8 can be completely dried.

[0091] Reference Figures 7-10 In some embodiments of this application, along the second direction of the furnace body 1, the sidewall of the inner shell 17 of the heating section 14 has a first wall surface 171 and a second wall surface 172 that are opposite to each other and spaced apart. In some specific embodiments, the front end wall of the inner shell 17 is the first wall surface 171, and the rear end wall of the inner shell 17 is the second wall surface 172. The first wall surface 171 is provided with an air inlet 1711, and the second wall surface 172 is provided with an air outlet 1721. Both the air inlet 1711 and the air outlet 1721 are constructed... The first air supply channel 141 is connected to the air inlet 1711, and the first air inlet channel 142 is connected to the air outlet 1721. The first hot air assembly 4 also includes a second heating element 43. The second heating element 43 is disposed in the first air inlet channel 142 and is opposite to the air inlet end of the first fan 41. In some specific embodiments, the second heating element 43 can be connected and cooperated with the outer top wall of the inner shell 17. In other specific embodiments, the second heating element 43 can be connected and cooperated with the inner peripheral wall of the outer shell 16.

[0092] Furthermore, a first connecting hole 161 is provided in the outer shell 16 of the heating part 14. The first connecting hole 161 is connected to the first air inlet channel 142 and the external environment. A first throttle valve 1611 is provided in the first connecting hole 161, which is used to adjust the gas flow rate in the first connecting hole 161.

[0093] Specifically, when the flip-type glass tunnel furnace 100 is started, the first throttle valve 1611 is fully opened, the first fan 41 draws gas from the external environment through the first connecting hole 161 and delivers it into the drying channel 11, and the first fan 41 simultaneously draws gas from the drying channel 11 through the air outlet 1721. The second heating element 43 heats the gas in the first air inlet channel 142, and the first heating element 42 heats the gas in the first air delivery channel 141, thereby achieving the technical effect of quickly raising the temperature inside the furnace body 1 to the preset temperature.

[0094] Furthermore, as the temperature inside the furnace body 1 gradually rises to the preset temperature, the first throttle valve 1611 gradually closes, thereby controlling the amount of gas drawn from the external environment by the first fan 41. This prevents the ambient temperature gas from entering the first air inlet channel 142 from mixing with the gas in the first air inlet channel 142 and lowering the gas temperature in the first air inlet channel 142, thus reducing the time required to raise the temperature inside the furnace body 1 to the preset temperature.

[0095] Furthermore, when the temperature inside the furnace body 1 rises to the preset temperature, the first throttle valve 1611 is completely closed, the first fan 41 draws gas from the drying channel 11 into the first air inlet channel 142, the second heating element 43 heats the gas in the first air inlet channel 142, and then the first fan 41 re-transports the gas in the first air inlet channel 142 back into the drying channel 11, thereby realizing gas circulation inside the furnace body 1. The first heating element 42 and the second heating element 43 do not need to heat the gas in the external environment, which can reduce the energy consumption of the first heating element 42 and the second heating element 43, and thus reduce the energy consumption of the flip-type glass tunnel furnace 100.

[0096] Furthermore, when the temperature inside the furnace body 1 is higher than the preset temperature, the operator can also adjust the amount of gas from the external environment entering the first air inlet channel 142 through the first throttle valve 1611, so as to adjust the gas temperature of the gas blown into the furnace body 1 by the first blower 41, thereby achieving the technical effect of adjusting the temperature inside the furnace body 1.

[0097] In some specific embodiments, the second heating element 43 can be a ceramic heating element, but this application is not limited to this. The second heating element 43 can also be an iron mesh made of heating wire, etc.

[0098] Reference Figure 10 and Figure 11In some embodiments of this application, a second connecting hole 162 is provided in the outer shell 16 of the heating section 14, which is connected to the first air inlet channel 142. A third connecting hole 163 is provided in the outer shell 16 of the heating section 14, which is located on the side of the heating section 14 near the cooling section 15. That is, along the first direction of the furnace body 1, the second connecting hole 162 is located to the right of the third connecting hole 163. The third connecting hole 163 is located at the tail of the heating section 14. The third connecting hole 163 is connected to both the second connecting hole 162 and the drying channel 11. A second throttle valve 1621 is provided in the second connecting hole 162, which is used to adjust the gas flow rate in the second connecting hole 162.

[0099] It should be noted that the tail end of the heating section 14 is the end of the heating section 14 near the cooling section 15, and the head end of the heating section 14 is the end of the heating section 14 near the feed inlet 12.

[0100] Specifically, after the temperature inside the furnace body 1 rises to the preset temperature, the first throttle valve 1611 closes and the second throttle valve 1621 opens. The first fan 41 draws gas from the tail of the heating section 14 through the second connecting hole 162 and the third connecting hole 163. The gas at the tail of the heating section 14 is reheated by the first heating element 42 and the second heating element 43 and then transported back to the drying channel 11 by the first fan 41. This achieves the technical effect of recycling the gas at the tail of the heating section 14 and reduces the energy consumption of the flip-type glass tunnel furnace 100.

[0101] Furthermore, the amount of gas drawn from the tail of the heating section 14 by the first blower 41 can be adjusted by the second throttle valve 1621. The operator can control the opening degree of the second throttle valve 1621 according to the temperature inside the furnace body 1. This can prevent a large amount of gas from the tail of the heating section 14 from being drawn into the first gas delivery channel by the first blower 41. It can also prevent the first heating element 42 and the second heating element 43 from failing to heat the gas at the tail of the heating section 14 to the preset temperature, which would cause the temperature inside the furnace body 1 to be lower than the preset temperature. Thus, the technical effect of maintaining the temperature inside the furnace body 1 at the preset temperature can be achieved.

[0102] Reference Figures 12-14In some embodiments of this application, the cold air assembly 5 includes a second fan 51 and a cooling fin assembly 52. ​​The second fan 51 is disposed on the outer shell 16 of the furnace body 1. The air inlet end of the second fan 51 extends into the drying channel 11 and is connected to the drying channel 11. An installation space 151 is defined between the inner side wall of the outer shell 16 and the outer side wall of the inner shell 17 of the cooling section 15. The outer shell 16 is provided with a fourth connecting hole 164, and the inner shell 17 is provided with a fifth connecting hole 173. Both the fourth connecting hole 164 and the fifth connecting hole 173 are constructed as through holes and are connected to the installation space 151. The cooling fin assembly 52 is disposed in the installation space 151 and is opposite to the fifth connecting hole 173. Cooling liquid flows in the cooling fin assembly 52. ​​The cooling fin assembly 52 is used to cool gas, and the second fan 51 is used to draw gas from the drying channel 11.

[0103] In some specific embodiments, along the second direction of the furnace body 1, an installation space 151 is defined between the front sidewall of the outer shell 16 and the front sidewall of the inner shell 17. The front sidewall of the outer shell 16 is provided with a fourth connecting hole 164, and the front sidewall of the inner shell 17 is provided with a fifth connecting hole 173. In other specific embodiments, an installation space 151 is defined between the rear sidewall of the outer shell 16 and the rear sidewall of the inner shell 17. The rear sidewall of the outer shell 16 is provided with a fourth connecting hole 164, and the rear sidewall of the inner shell 17 is provided with a fifth connecting hole 173.

[0104] When the glass plate 8 is transported to the cooling section 15, the second fan 51 first draws the gas from the external environment into the drying channel 11 through the fourth connecting hole 164 and the fifth connecting hole 173. Then, the second fan 51 draws the gas in the drying channel 11 into the external environment. As the gas from the external environment enters the drying channel 11 through the fourth connecting hole 164 and the fifth connecting hole 173, the gas passes through the cooling fin assembly 52 and exchanges heat with the cooling fin assembly 52. ​​The cooling fin assembly 52 cools the gas to a preset temperature. Then, the cooled gas enters the drying channel 11 to cool the glass plate 8, thereby achieving the technical effect of the cold air assembly 5 cooling the glass plate 8.

[0105] It should be noted that the cooling fin assembly 52 includes multiple cooling fins and cooling pipes. The multiple cooling fins are spaced apart along the first direction of the furnace body 1. The cooling pipes pass through the multiple cooling fins and cooling liquid flows in the cooling pipes. When the gas passes through the cooling fin assembly 52, the gas exchanges heat with the cooling fins, and the cooling fins cool the gas.

[0106] In some specific embodiments, the cooling liquid can be liquid nitrogen, but this application is not limited to this; the cooling liquid can also be water at 0°-15°, etc.

[0107] In some specific embodiments, the second fan 51 can be a long-shaft fan, etc.

[0108] Furthermore, there are two installation spaces 151 and two cooling fin groups 52. One of the two installation spaces 151 is located in front of the inner shell 17, and the other of the two installation spaces 151 is located behind the inner shell 17. One of the two cooling fin groups 52 is located in front of the inner shell 17, and the other of the two cooling fin groups 52 is located behind the inner shell 17. The front and rear walls of the outer shell 16 are provided with fourth connecting holes 164, and the front and rear walls of the inner shell 17 are provided with fifth connecting holes 173. This arrangement can increase the amount of gas drawn from the external environment into the drying channel 11 by the second fan 51, thereby achieving the technical effect of quickly cooling the glass plate 8 to the preset temperature.

[0109] Reference Figures 12-14 In some embodiments of this application, the cooling air assembly 5 may further include a third fan 53, which is disposed in the installation space 151 and located between the cooling fin assembly 52 and the inner shell 17. The air inlet of the third fan 53 is opposite to the cooling fin assembly 52, and the air outlet of the third fan 53 is opposite to the fifth connecting hole 173.

[0110] By setting a third fan 53 between the cooling fin assembly 52 and the fifth connecting hole 173, the third fan 53 can assist the second fan 51 in drawing gas from the external environment into the drying channel 11. This can minimize the attenuation of the suction power of the second fan 51 within the installation space 151, thus preventing insufficient suction power and the inability of the second fan 51 to draw enough gas into the drying channel 11. This can prevent the glass plate 8 from failing to cool to the preset temperature, thereby improving the operational reliability of the flip-type glass tunnel furnace 100.

[0111] In some specific embodiments, the third fan 53 can be an axial flow fan or the like.

[0112] Furthermore, there can be multiple third fans 53, fourth connecting holes 164, and fifth connecting holes 173. These multiple third fans 53, fourth connecting holes 164, and fifth connecting holes 173 are spaced apart along the radial direction of the furnace body 1, and are arranged in a one-to-one correspondence. This arrangement allows multiple third fans 53 to jointly draw gas from the external environment into the drying channel 11, thereby achieving the technical effect of quickly cooling the glass plate 8 to a preset temperature. It should be noted that the cooling fin assembly 52 can completely cover the multiple third fans 53, fourth connecting holes 164, and fifth connecting holes 173.

[0113] Reference Figure 1 and Figure 15 In some embodiments of this application, along the first direction of the furnace body 1, the furnace body 1 may further include a preheating section 18, the preheating section 18 being located on the side of the heating section 14 near the feed inlet 12. Along the height direction of the furnace body 1, a second air supply channel 181 and a second air inlet channel 182 are defined between the upper end wall of the outer shell 16 and the upper end wall of the inner shell 17 of the preheating section 18. The second air inlet channel 182 and the second air supply channel 181 are spaced apart and communicate with the external environment. Gas in the external environment enters between the outer shell 16 and the inner shell 17 through the second air inlet channel 182. The second air supply channel 181 communicates with the drying channel 11.

[0114] The flip-type glass tunnel furnace 100 also includes a second hot air assembly 6, which includes a fourth fan 61 and a third heating element 62. The fourth fan 61 is disposed in the outer shell 16 of the furnace body 1. Both the air inlet and outlet of the fourth fan 61 extend between the outer shell 16 and the inner shell 17. The air inlet of the fourth fan 61 is connected to the second air inlet channel 182, and the air outlet of the fourth fan 61 is connected to the second air supply channel 181. The third heating element 62 is disposed within the second air supply channel 181 and... In some specific embodiments, the third heating element 62 can be connected and cooperated with the outer top wall of the inner shell 17, and in other specific embodiments, the third heating element 62 can be connected and cooperated with the inner peripheral wall of the outer shell 16. The fourth fan 61 is used to transport the gas in the second air supply channel 181 to the drying channel 11. The temperature of the gas blown into the drying channel 11 by the second hot air assembly 6 is lower than the temperature of the gas blown into the drying channel 11 by the first hot air assembly 4.

[0115] Specifically, when the glass plate 8 is placed on the plate frame 21 at the feed inlet 12, the glass plate 8 first passes through the preheating section 18, then the heating section 14, and finally the cooling section 15. In the preheating section 18, the fourth fan 61 draws the gas from the external environment into the drying channel 11. When the gas from the external environment flows into the second air supply channel 181, the third heating element 62 heats the gas in the second air supply channel 181. The temperature of the gas in the second air supply channel 181 is lower than the temperature of the gas in the first air supply channel 141. This achieves the technical effect of preheating the glass plate 8 and gradually drying the ink on the glass plate 8. It avoids direct contact between the ink and the high-temperature gas, prevents the ink from expanding and deforming, and improves the operational reliability of the flip-type glass tunnel furnace 100.

[0116] In some specific embodiments, the fourth fan 61 can be a long-shaft fan, and the third heating element 62 can be a ceramic heating element, but this application is not limited to this. The third heating element 62 can also be an iron mesh made of heating wire, etc.

[0117] Reference Figure 1 and Figure 16 In some embodiments of this application, the flip-type glass tunnel furnace 100 may further include: a fifth fan 7, which is disposed on the outer shell 16 of the furnace body 1 and located on the side of the preheating section 18 near the feed inlet 12. The air inlet end of the fifth fan 7 extends into the drying channel 11 and is connected to the drying channel 11. The fifth fan 7 is used to draw gas from the drying channel 11 to regulate the temperature inside the drying channel 11.

[0118] Specifically, the fifth fan 7 draws the gas in the drying channel 11 to the external environment, thereby preventing the continuous accumulation of high-temperature gas in the drying channel 11 and avoiding the temperature in the drying channel 11 from exceeding the preset temperature. This achieves the technical effect of regulating the temperature in the drying channel 11 to maintain the temperature in the drying channel 11 at the preset temperature.

[0119] In some specific embodiments, the fifth fan 7 can be a centrifugal fan, etc.

[0120] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
