Description

Technical Field

[0001] This invention belongs to the technical field of glass production equipment, specifically relating to a flow controller and glass forming system that can control the distribution of molten glass. Background Technology

[0002] In the vertical pull forming process of ultra-thin glass (such as TFT, UTG, UFG with a thickness ≤1mm), after the molten glass flows out from the buffer furnace or platinum hopper, it finally enters the annealing furnace to solidify and form. The distribution state of the molten glass during the falling process, that is, the cross-sectional shape, thickness and width of the molten glass falling, directly affects the thickness uniformity, warpage and forming stability of the formed glass plate. Current technologies primarily rely on a sizing furnace or transition channel located below the buffer furnace or platinum hopper to adjust the distribution of molten glass during its descent. However, since the sizing head and transition channel adjust the glass based on its already established flow pattern and inertia, their response is lag-dependent. This not only makes adjustment difficult but also exposes the sizing furnace and transition channel to strong scouring and thermal effects from the molten glass during the adjustment process, leading to rapid aging and thermal deformation. This results in increasingly inaccurate adjustments to the glass distribution, requiring frequent maintenance and incurring high operating costs. Furthermore, by the time the molten glass reaches the sizing furnace or transition channel, its fluidity has significantly decreased due to heat dissipation. When the sizing furnace and transition channel adjust the glass distribution, the molten glass tends to accumulate and adhere within these spaces, increasing the frequency of glass breakage. The complex and bulky structure of the sizing furnace and transition channel also makes daily cleaning and maintenance difficult. Therefore, improvements and optimizations to the structure or process for adjusting the molten glass distribution are needed to reduce the difficulty and cost of glass sheet forming. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a flow controller and glass forming system that can control the distribution of molten glass, solve the technical problem of inconvenient adjustment of the distribution state of molten glass, and achieve the effect of improving the quality of glass forming and reducing the difficulty of production.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A flow controller for controlling the distribution of molten glass includes a base plate, flow control sliders, flow control clamps, a first driving member, and a second driving member. The base plate has a flow control port that vertically penetrates the base plate. Two flow control sliders are located within the flow control port and are distributed along the length of the port. The flow control sliders are slidably connected to the base plate. The first driving member is driven by the two flow control sliders and can drive them to slide laterally closer together or further apart. This lateral movement of the two flow control sliders can adjust the distribution width of the molten glass. Two flow control clamps are located on either side of the flow control port's width direction. Each clamp has a first end and a second end vertically. The first end of each clamp is rotatably connected to the base plate. The second driving member is driven by the two flow control clamps and can drive the second ends of the clamps to rotate closer together or further apart. This rotation of the second ends of the clamps can adjust the distribution thickness of the molten glass.

[0006] Furthermore, the flow control clamp is located below the base plate, and the upper end of the flow control clamp is rotatably connected to the base plate. Multiple docking grooves are provided on the upper surface of the base plate, and the multiple docking grooves are distributed in a matrix around the flow control port.

[0007] Furthermore, a locking pin is provided laterally inside the docking groove, with one end of the locking pin extending movably out of the bottom plate.

[0008] Furthermore, the upper surface of the base plate has two horizontally opposing docking baffles protruding, with the docking groove and flow control port located between the two docking baffles, which are located on both sides of the flow control clamp.

[0009] Furthermore, multiple hoisting lugs are provided around the base plate.

[0010] Furthermore, it also includes platinum side plates, which are installed on the two side walls inside the flow control port, close to the flow control clamp, and the platinum side plates are flush with the side walls.

[0011] Furthermore, an installation groove is provided on the side wall where the platinum side plate is located. Multiple mating ribs are raised on the bottom surface of the installation groove. The mating ribs are flush with the side wall. The platinum side plate is located in the installation groove and is sized to fit. The platinum side plate has multiple mating notches that correspond one-to-one with the multiple mating ribs. The mating ribs are located in the corresponding mating notches and are interference-fitted.

[0012] Furthermore, the mounting groove extends vertically to the upper surface of the base plate, and the upper surface of the platinum side plate inside the mounting groove is flush with the upper surface of the base plate.

[0013] Furthermore, the opposing sides of the two flow control sliders are upward-facing slopes.

[0014] Furthermore, a platinum guide plate is provided on the inclined surface.

[0015] Furthermore, a connecting groove is provided on the inclined surface, and a connecting rib corresponding to the connecting groove is formed on the side of the platinum guide plate facing the inclined surface. The connecting rib is located in the connecting groove and is interference-fitted.

[0016] Furthermore, threaded holes are provided on the opposite sides of the two flow control sliders, and a transmission rod is threaded into the threaded hole. The transmission rod extends movably out of the base plate. The first driving component includes two first motors that correspond one-to-one with the two flow control sliders. The first motors are located outside the base plate and their output shafts are connected to the transmission rods on the corresponding flow control sliders.

[0017] Furthermore, the flow control clamp is rotatably connected to the base plate via a rotating shaft set along the long side of the control opening. The second driving component includes two second motors corresponding to the two flow control clamps. The second motors are located outside the base plate and their output shafts are connected to the rotating shafts of the corresponding flow control clamps.

[0018] The present invention also includes a glass forming system for controlling the distribution of molten glass. The glass forming system includes a blanking device, a shaping furnace, and a flow controller for controlling the distribution of molten glass as described above. The blanking device is located above the shaping furnace, and the flow controller is located between the blanking device and the shaping furnace. The blanking port of the blanking device is vertically aligned with the flow controller port and located between the two docking baffles. The lower end of the blanking port has a protrusion forming a plurality of docking protrusions. The docking protrusions have transverse through pin holes. The plurality of docking protrusions are inserted one-to-one into the plurality of docking grooves, and a portion of the locking pin in the docking groove is located in the corresponding pin hole.

[0019] Furthermore, thermal insulation cotton is filled between the docking baffle and the outer wall of the material discharge port.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The flow controller for controlling the distribution of molten glass described in this invention, during use, adjusts the distance between the two flow control sliders and the distance between the lower ends of the two flow control clamps according to the forming requirements. The inclined surfaces on the opposing surfaces of the flow control sliders obstruct and guide the distribution width of the molten glass, while the flow control clamps obstruct and guide the distribution thickness of the molten glass, making the distribution width and thickness of the molten glass close to the glass sheet to be formed. This allows the molten glass to be pre-adjusted at the stage when it just flows out of the discharge port, with a relatively high temperature and good fluidity, reducing the amount of adjustment required by subsequent distribution adjustment equipment such as the setting furnace and transition channel. This reduces the difficulty and lag in adjusting the distribution state of the molten glass. Simultaneously, the pre-adjustment reduces the scouring and thermal effects of the molten glass on distribution adjustment equipment such as the setting furnace, delaying aging and thermal deformation, improving the stability of glass forming quality, and reducing maintenance frequency and production costs.

[0022] 2. The flow controller for controlling the distribution of molten glass described in this invention, through the docking groove, locking pin, and protruding docking baffle arranged around the flow control port, together form a docking structure that provides quick positioning, locking and fixing, and good sealing and heat preservation functions. This structure can ensure that the flow controller and the discharge port of the discharge equipment can be docked quickly, accurately, and reliably connected, while effectively reducing heat loss at the docking point. It is convenient for installation and maintenance, and also helps to maintain the fluidity and temperature uniformity of the molten glass.

[0023] 3. The flow controller for controlling the distribution of molten glass described in this invention, by setting a replaceable platinum side plate on the side wall of the flow control port and covering the inclined surface of the flow control slider with a platinum guide plate, together constitutes a platinum protection system for the core contact components. This system utilizes the excellent high-temperature resistance and corrosion resistance of platinum material to effectively isolate the high-temperature molten glass from the main structure of the flow controller (base plate and flow control slider), reducing the risk of thermal deformation and aging of the main components. Each platinum component is installed and connected by an interference fit, which ensures structural stability while also making it easy to replace individually, extending the overall life of the flow controller and reducing maintenance costs.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] Example:

[0034] Please see Figure 1 , Figure 2 and Figure 3 A flow controller for controlling the distribution of molten glass includes a base plate 1, flow control sliders 2, flow control clamps 3, a first driving member, and a second driving member. The base plate 1 has a flow control port 4 that vertically penetrates the base plate 1. Two flow control sliders 2 are located within the flow control port 4 and are distributed along the length of the flow control port 4. The flow control sliders 2 are slidably connected to the base plate 1. The first driving member is driven by the two flow control sliders 2 and is used to drive the two flow control sliders 2 to slide closer together or further apart, thereby adjusting the distribution width of the molten glass 23 flowing through it. Two flow control clamps 3 are located on either side of the width direction of the flow control port 4. Each flow control clamp 3 has a first end and a second end vertically. The first end of the flow control clamp 3 is rotatably connected to the base plate 1. The second driving member is driven by the two flow control clamps 3 and is used to drive the two flow control clamps 3 to rotate, causing the second end of the flow control clamp 3 to rotate accordingly. The movement of the flow control plates 3 towards or away from each other allows for adjustment of the thickness of the molten glass distribution. Understandably, for this adjustment, the second end of the flow control plate 3 moving towards the other end during rotation refers to the movement when the lateral distance between the second ends of the two flow control plates 3 is less than the inner width of the flow control port 4. The movement of the second end of the flow control plate 3 moving away during rotation refers to the movement when the lateral distance between the second ends of the two flow control plates 3 is less than the inner width of the flow control port 4. The first driving component can be driven unidirectionally, even if the two flow control sliders 2 move towards or away from each other. The second driving component can also be driven unidirectionally, even if the second ends of the two flow control plates 3 move towards or away from each other during rotation. After one adjustment, when readjustment is required, the flow control sliders 2 and flow control plates 3 must be manually reset. In this embodiment, both the first and second driving components can be driven bidirectionally, making the adjustment of the molten glass distribution more flexible and efficient.

[0035] Please see Figure 3 , Figure 4 and Figure 6In this embodiment, the flow control port 4 is rectangular and adapted to the discharge port 22 of the discharge device. Two flow control sliders 2 are respectively located near the two side walls where the wide side of the flow control port 4 is located. The flow control sliders 2 slide in cooperation with the two side walls where the long side of the flow control port 4 is located. Specifically, the two side walls where the long side of the flow control port 4 is located have grooves 6 extending along the long side. The two sides of the flow control sliders 2 opposite to the two side walls where the long side of the flow control port 4 are located have sliding ribs 7 adapted to the grooves 6. The sliding ribs 7 are located within the grooves 6 and slide in cooperation, allowing the flow control sliders 2 to slide along the long side of the flow control port 4, thereby smoothly adjusting the distribution width of the flowing molten glass. Two flow control clamps 3 are respectively located near the long side of the flow control port 4. On both sides of the edge, the flow control clamp 3 is located below the base plate 1. The flow control clamp 3 extends along the long side of the flow control port 4 and its length is greater than the maximum distance between the two flow control sliders 2, so that the two flow control clamps 3 can adapt to various distances of the two flow control sliders 2. The upper end of the flow control clamp 3 is rotatably connected to the base plate 1. The two flow control clamps 3 can rotate so that their lower ends move closer or further apart. In order to ensure the effectiveness of adjusting the thickness of the glass liquid distribution by bringing the lower ends of the two flow control clamps 3 closer or further apart, in this embodiment, the upper end of the flow control clamp 3 is designed to be constrained by the base plate 1, so that the flow control clamp 3 can only rotate within the range from its lower end vertically downward to its lower end abutting against each other.

[0036] The flow controller for controlling the distribution of molten glass described in this invention is installed below a feeding device such as a buffer furnace or platinum hopper, and connected to the feeding port of the feeding device. A first driving component drives two flow control sliders 2 to slide, adjusting the distance between the two sliders. The sliders 2 then block and guide the molten glass along the length of the flow control port 4 (i.e., the distribution width of the molten glass), making the distribution width of the molten glass close to the width of the glass sheet to be formed. A second driving component drives two flow control clamps 3 to rotate, adjusting the distance between their lower ends to control the distribution of the molten glass. The flow outlet 4 is blocked and guided in the width direction (i.e., the distribution thickness of the molten glass) to make the distribution thickness of the molten glass close to the thickness of the glass sheet to be formed. In this way, the molten glass is pre-adjusted in the stage when it just flows out of the discharge port, when the temperature is high and the fluidity is good. This reduces the amount of adjustment required by the subsequent shaping head or transition channel, thereby reducing the difficulty and lag in adjusting the distribution state of the molten glass. At the same time, the pre-adjustment reduces the scouring and thermal effects of the molten glass on the shaping head, etc., delays aging and thermal deformation, improves the stability of glass forming quality, and reduces maintenance frequency and production costs.

[0037] Please see Figure 1 , Figure 4 and Figure 5The upper surface of the base plate 1 has multiple docking grooves 8, which are arranged in a matrix around the flow control port 4. In this way, the multiple docking grooves 8 on the base plate 1 are arranged in a matrix around the flow control port 4. In use, a downward docking protrusion is set at the lower end of the material discharge port of the material discharge device. When the flow controller is docked with the material discharge port, the docking protrusion is inserted into the docking groove 8 to achieve rapid docking and positioning. This ensures accurate communication between the flow control port 4 and the material discharge port, avoids deviation in the flow of molten glass, improves installation efficiency and docking accuracy, and thus ensures the stability of the distribution adjustment of molten glass.

[0038] Please see Figure 4 and Figure 5 A locking pin 9 is provided laterally inside the docking groove 8, with one end of the locking pin 9 extending movably out of the base plate 1. In this way, the locking pin 9 in the docking groove 8 can move laterally. During docking, the locking pin 9 is first pulled out, and after the docking protrusion is inserted into the docking groove 8, the locking pin 9 is then inserted into the pin hole of the base plate 1 and the docking protrusion, realizing the detachable connection between the base plate 1 and the discharge port. This structure simplifies the installation and disassembly process of the flow controller, facilitates daily maintenance, cleaning or replacement, reduces operating costs, and improves the flexibility and reliability of the equipment.

[0039] Please see Figure 1 , Figure 4 and Figure 5 The upper surface of the base plate 1 has two horizontally opposing docking baffles 10. The docking groove 8 and the flow control port 4 are located between the two docking baffles 10, which are located on both sides of the flow control clamp 3. In this way, the docking baffles 10 protruding on the upper surface of the base plate 1 extend along the long side of the flow control port 4 to form an inverted concave platform structure, which cooperates with the outer wall surface of the flow control port when docking with the flow control device. This not only enhances the stability and sealing of the docking, but also reduces heat loss and helps to maintain the fluidity and temperature uniformity of the glass melt. In practice, insulation cotton can be added between the docking baffles 10 and the outer wall surface of the flow control port to further optimize the insulation effect and improve the energy efficiency of the forming process.

[0040] Please see Figure 1 and Figure 4 The base plate 1 is provided with multiple hoisting lugs 11 around its perimeter. These hoisting lugs 11 facilitate handling and installation using hoisting equipment, which simplifies the deployment and replacement process of the flow controller, reduces the difficulty and time of manual operation, and improves the flexibility and maintenance efficiency of the production line.

[0041] Please see Figure 1The flow controller of the present invention also includes a platinum side plate 13, which is installed on two long side walls inside the flow control port 4. The long side walls are the inner walls along the length of the flow control port 4, and the platinum side plate 13 is flush with the long side walls. In this way, the platinum side plate 13 on the long side wall of the flow control port 4 separates the molten glass from the base plate 1. By utilizing the high temperature corrosion resistance of platinum material, the risk of the base plate 1 being corroded and deformed by high temperature is reduced, thus extending the service life of the flow controller.

[0042] Please see Figure 1 and Figure 4 A mounting groove 12 is provided on the long side wall where the platinum side plate 13 is located. Multiple mating ribs 14 are raised on the bottom surface of the mounting groove 12. The mating ribs 14 are flush with the long side wall. The platinum side plate 13 is located in the mounting groove 12 and is sized to fit. The platinum side plate 13 has multiple mating notches that correspond one-to-one with the multiple mating ribs 14. The mating ribs 14 are located in the corresponding mating notches and are interference-fitted. In this way, the platinum side plate 13 is set on the long side wall of the flow control port 4 through the mounting groove 12. Maintenance can be carried out by periodically replacing the platinum side plate 13, which reduces the overall operating cost. In addition, the interference fit between the mating ribs 14 on the bottom surface of the mounting groove 12 and the mating notches on the platinum side plate 13 increases the contact area and connection strength between the platinum side plate 13 and the mounting groove 12. This ensures that the platinum side plate 13 is stably fixed in high temperature and vibration environments, prevents displacement or loosening, and improves the reliability and safety of the equipment.

[0043] Please see Figure 1 and Figure 4 The mounting groove 12 extends vertically to the upper surface of the base plate 1, and the upper surface of the platinum side plate 13 inside the mounting groove 12 is flush with the upper surface of the base plate 1. In this way, since the upper edge of the control opening is severely eroded by the molten glass, the mounting groove 12 is further limited to extend to the upper surface of the base plate 1, so that the upper surface of the platinum side plate 13 is flush with the upper surface of the base plate 1. Thus, the platinum side plate 13 takes over the erosion from the upper edge, which helps to further improve the service life of the base plate 1.

[0044] Please see Figure 1 and Figure 6 The two flow control sliders 2 have an upward-facing inclined surface 5 on their opposite sides. In this way, by using the inclined surface 5 on the opposite side of the flow control sliders 2, when the flow control sliders 2 block and guide the glass liquid in the length direction of the flow control port 4 (i.e. the distribution width of the glass liquid), the inclined surface 5 is more conducive to guiding the glass liquid flow to concentrate, thereby reducing the distribution width of the glass liquid.

[0045] Please see Figure 1 and Figure 6A platinum guide plate 15 is provided on the inclined surface 5; in this way, the platinum guide plate 15 covering the inclined surface 5 of the flow control slider 2 separates the molten glass from the flow control slider 2. The platinum guide plate 15 is resistant to high temperature and corrosion, protects the flow control slider 2 from thermal deformation and wear, and helps to improve the service life of the flow control slider 2.

[0046] Please see Figure 1 and Figure 6 A connecting groove 16 is provided on the inclined surface 5. The platinum guide plate 15 has a connecting rib protruding on the side facing the inclined surface 5, which corresponds to the connecting groove 16. The connecting rib is located in the connecting groove 16 and is interference-fitted. In this way, the platinum guide plate 15 is installed with the connecting groove 16 through the connecting rib, which facilitates the maintenance of the flow control slider 2 by periodically replacing the platinum guide plate 15, and helps to reduce the maintenance difficulty. In this embodiment, the base plate 1 is made of chromium-nickel alloy, and the platinum side plate 13 and the platinum guide plate 15 are made of platinum or platinum-rhodium alloy.

[0047] Please see Figure 1 and Figure 6 Two flow control sliders 2 have threaded holes on their opposite sides. A transmission rod 17 is threaded into the threaded hole and is also threaded into the base plate 1, extending outside the base plate 1. The first driving component includes two first motors 18 corresponding to the two flow control sliders 2. The first motors 18 are located outside the base plate 1 and their output shafts are connected to the transmission rods 17 on the corresponding flow control sliders 2. In this way, the threaded holes on the flow control sliders 2 are threaded into the transmission rods 17, and the first motors 18 drive the transmission rods 17 to rotate, forming a screw drive structure. This enables precise linear movement of the two flow control sliders 2, facilitating precise adjustment of the distribution width of the molten glass 23.

[0048] Please see Figure 1 , Figure 2 and Figure 3 A rotating shaft 19 is rotatably connected to the base plate 1 along the length of the flow control port 4. There are two rotating shafts 19, each corresponding to one of the two flow control plates 3. The flow control plates 3 are fixedly connected to the corresponding rotating shafts 19, so that the flow control plates 3 are rotatably connected to the base plate 1 through the corresponding rotating shafts 19. The second driving component includes two second motors 20 corresponding to the two flow control plates 3. The second motors 20 are located outside the base plate 1 and their output shafts are connected to the rotating shafts 19 of the corresponding flow control plates 3. In this way, the flow control plates 3 are rotatably connected to the base plate 1 through the rotating shafts 19. The second motors 20 drive the rotating shafts 19 to control the rotation angle of the flow control plates 3, thereby achieving precise adjustment of the distance between the lower ends of the two flow control plates 3, which facilitates precise adjustment of the distribution thickness of the glass melt 23. In this embodiment, each rotating shaft 19 is connected to two ends of a second motor 20. The second motors 20 at both ends of the rotating shaft 19 rotate synchronously to drive the rotating shaft 19, which helps to reduce bending moment and vibration.

[0049] Please see Figure 1 , Figure 5 and Figure 7 The present invention also includes a glass forming system for controlling the distribution of molten glass. The glass forming system includes a blanking device, a shaping furnace 21, and a flow controller for controlling the distribution of molten glass as described above. The blanking device is located above the shaping furnace 21, and the flow controller is located between the blanking device and the shaping furnace 21. The blanking port 22 of the blanking device is vertically aligned with the flow controller port 4 and located between the two docking baffles 10. The lower end of the blanking port 22 has a protrusion forming multiple docking protrusions (not shown in the figure). Each docking protrusion has a transversely penetrating pin hole. The multiple docking protrusions are inserted one-to-one into the multiple docking grooves 8 for docking. A portion of the locking pin 9 in the groove 8 is located in the corresponding pin hole; in this embodiment, the space between the docking baffle 10 and the outer wall of the discharge port 22 is filled with insulating cotton (not shown in the figure); thus, the glass forming system with controllable glass melt distribution of the present invention performs preliminary distribution adjustment of glass melt 23 through the flow controller, and then completes the final forming through the shaping furnace 21 (distribution adjustment equipment), realizing step-by-step adjustment, which reduces the burden on the distribution adjustment equipment, reduces the risk of glass melt 23 accumulation and adhesion, improves forming stability and glass quality, and at the same time reduces the frequency of plate breakage and maintenance costs, and optimizes the vertical pull forming process as a whole.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of the present invention without departing from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
