Description

Technical Field

[0001] This invention relates to the field of glass production technology, specifically to a production apparatus and process for ultra-thin photovoltaic glass. Background Technology

[0002] Photovoltaic glass is a special type of glass material mainly used in solar photovoltaic power generation systems to protect solar panels while increasing light transmittance, thereby increasing the power generation efficiency of the entire photovoltaic system. It can also be used in building-integrated photovoltaics as windows or curtain walls, which are both aesthetically pleasing and power-generating.

[0003] Traditional photovoltaic glass is mostly produced using the float glass process, where molten glass is poured onto molten tin to form a smooth glass surface. To improve solar energy absorption efficiency, ultra-thin photovoltaic glass is used. However, there are still some problems when using the float glass process to produce ultra-thin photovoltaic glass: because the produced photovoltaic glass is relatively thin, the amount flowing into the tin bath needs to be precisely controlled, and it needs to be laid flat and stable on the surface of the tin bath. Due to the thinness of the molten glass, uneven temperature in the tin bath can cause some parts to cool faster than others, easily resulting in defects in the glass forming. Furthermore, the glass needs to be annealed separately in an annealing chamber, making the process quite complex. Therefore, we propose a production device and process for ultra-thin photovoltaic glass to solve the above problems. Summary of the Invention

The liquid storage cylinder is located between a first L-shaped partition and a second L-shaped partition. Two liquid guide heads are fixedly installed at the bottom of the liquid storage cylinder.

[0013] As a preferred embodiment of the present invention, the unloading mechanism includes an unloading inclined frame, and an unloading groove corresponding to the unloading mechanism is opened in the middle of the end of the molten tin tank away from the material control mechanism. One end of the unloading inclined frame is fixedly engaged in the unloading groove, and a plurality of electric guide rollers are evenly distributed on the inner bottom of the unloading inclined frame. The plurality of electric guide rollers are inclined.

[0014] A manufacturing process for an ultrathin photovoltaic glass production apparatus includes the following steps:

[0015] Step 1: Place the molten tin above the first L-shaped partition and the second L-shaped partition. By setting up multiple heating modules distributed in a rectangular array, the temperature of the molten tin can be controlled in a rectangular array, thereby precisely controlling the temperature of each area of ​​the molten tin. And through multiple traction mechanisms, the glass solution flowing on the surface of the molten tin is stretched and pulled to make the glass solution ultra-thin.

[0016] According to the thinness requirements of photovoltaic glass, the second telescopic cylinder is opened to extend or retract, which drives the control shaft to slide in the arc groove, thereby controlling the bottom support inclined plate to rotate around the rotating shaft column, flexibly adjusting the tilt angle of the bottom support inclined plate, thereby flexibly adjusting the angle at which the glass solution is introduced into the tin liquid tank.

[0017] And by controlling the extension and retraction of the first telescopic cylinder, the drive sleeve slides in the arc-shaped adjustment groove, thereby controlling the top pressure component to rotate around one of the top pressure rollers as an axis, adjusting the tilt angle of the top pressure component, thereby flexibly adjusting the length of the rolling gap, so as to roll out ultra-thin glass liquid of appropriate thickness according to the requirements.

[0018] Step 2: The mixed molten glass solution is introduced into the molten tin tank at a certain angle through the feeding trough, onto the upper surface of the molten tin. During this process, the second motor is activated to drive the drive shaft to rotate the second gear. In conjunction with the meshing of multiple differential gears and the first gear, the driving adjustment shaft rotates slowly, causing the liquid control rod to rotate. The size of the drain port is flexibly adjusted to accurately control the amount of glass solution flowing into the molten tin tank. This ensures that the glass solution is spread evenly on the upper surface of the molten tin in an effective and precise manner, forming an ultra-thin layer of molten glass on the upper surface of the molten tin. This facilitates the subsequent molding of ultra-thin glass. With the synchronous traction of multiple traction mechanisms, an ultra-thin layer of molten glass is formed on the upper surface of the molten tin. As the ultra-thin molten glass flows on the upper surface of the molten tin, its temperature gradually stabilizes and decreases uniformly.

[0019] During this process, when the molten tin level in the molten tin tank is high, the level needs to be lowered by controlling the activation of the bidirectional hydraulic pump. The molten tin in the molten tin tank is then guided into the storage tank for buffering through multiple connecting clamps, multiple guide branches and a main guide pipe, and a guide head, thereby lowering the molten tin level. When the molten tin level in the molten tin tank is low, the level needs to be raised by controlling the activation of the bidirectional hydraulic pump. The molten tin buffered in the storage tank is then guided into the molten tin tank through a guide head, a main guide pipe, multiple guide branches and multiple connecting clamps, thereby raising the molten tin level. This allows for flexible adjustment of the molten tin level so that the ultra-thin glass melt can flow and spread on the surface of the molten tin.

[0020] Step 3: Control the start of the first motor to drive the corresponding bottom support roller to rotate. With the meshing connection of the two transmission gears, drive the corresponding top pressure roller to rotate synchronously in the opposite direction. This controls the bottom support belt and the top pressure belt to transport synchronously in the opposite direction. The ultra-thin glass liquid flows and is transported on the upper surface of the molten tin in the first L-shaped partition. It passes between the bottom support belt and the top pressure belt. Due to the inclined setting of the top pressure belt and the synchronous reverse transport of the bottom support belt and the top pressure belt, the bottom support belt and the top pressure belt gradually roll and thin the front end of the ultra-thin glass liquid again. This makes the ultra-thin glass liquid flow even thinner on the upper surface of the molten tin in the second L-shaped partition to continue to flow and be transported for cooling. This is to form an even thinner ultra-thin glass liquid so as to form ultra-thin glass.

[0021] Step 4: The even thinner ultra-thin glass liquid is introduced into the unloading inclined frame through the unloading trough. With the control of multiple electric guide rollers, the even thinner ultra-thin glass liquid is tilted upwards and discharged from the tin liquid tank for subsequent annealing treatment.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. By setting up a material control mechanism, the angle at which the glass solution is introduced into the molten tin tank can be flexibly adjusted so that ultra-thin glass can be better formed on the upper surface of the molten tin. The size of the drain outlet can also be flexibly adjusted to accurately control the amount of glass solution flowing into the molten tin tank, so that the glass solution is spread evenly on the upper surface of the molten tin in an effective and accurate amount, and an ultra-thin glass layer is formed on the upper surface of the molten tin, so that ultra-thin glass can be formed subsequently.

[0024] 2. By setting up a pressure-bearing mechanism, the front end of the ultra-thin glass melt can be gradually rolled thinner again, so that the ultra-thin glass melt flows even thinner on the surface of the molten tin in the second L-shaped partition and continues to flow and transfer for cooling, thereby forming an even thinner ultra-thin glass melt, so as to form ultra-thin glass.

[0025] 3. By setting up a pressure-bearing mechanism, the length of the rolling gap can be flexibly adjusted so as to roll out ultra-thin glass melt of appropriate thickness according to requirements, thereby improving the flexibility of the entire device.

[0026] 4. By setting up a liquid control mechanism, the liquid level of the molten solder can be flexibly adjusted so that the ultra-thin glass melt can flow and spread on the surface of the molten solder. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example: Figure 1-15As shown, this invention provides a production apparatus for ultra-thin photovoltaic glass, including an apparatus base 1. A molten tin tank 2 is fixedly installed at the top of the apparatus base 1. A material control mechanism 3 is provided at one end of the molten tin tank 2. A first support 11 is fixedly installed at the bottom of the material control mechanism 3. The first support 11 is fixedly installed at the top of the apparatus base 1. A material ejection mechanism 4 is provided at the end of the molten tin tank 2 away from the material control mechanism 3. A second support 12 is fixedly installed at the bottom of the material ejection mechanism 4. The second support 12 is fixedly installed at the top of the apparatus base 1. A first L-shaped partition 21 is fixedly installed inside the molten tin tank 2 on the side near the material control mechanism 3. A second L-shaped partition 22 is fixedly installed inside the molten tin tank 2 on the side near the material ejection mechanism 4. Molten tin is placed above the first L-shaped partition 21 and the second L-shaped partition 22. Each of the components is equipped with a temperature control element, which includes multiple heating modules 23 arranged in a rectangular array. The heating modules 23 are fixedly installed on the corresponding first L-shaped partition 21 and second L-shaped partition 22. By setting multiple heating modules 23 arranged in a rectangular array, the temperature of the molten tin can be controlled in a rectangular array, thereby precisely controlling the temperature of each area of ​​the molten tin. This facilitates precise temperature control when the glass solution flows on the upper surface of the molten tin, which is conducive to the precise forming of ultra-thin glass. The top of the molten tin tank 2 is equipped with multiple traction mechanisms 24 evenly distributed. By setting multiple traction mechanisms 24, the glass solution flowing on the upper surface of the molten tin is stretched and pulled, so that the glass solution can be made ultra-thin. A pressure-bearing mechanism 5 is provided between the first L-shaped partition 21 and the second L-shaped partition 22. A liquid control mechanism 6 is provided at the bottom of the first L-shaped partition 21 and the second L-shaped partition 22.

[0046] The material control mechanism 3 includes two symmetrically distributed material control side frames 31, which are fixedly installed on the top of the first support 11. Bottom support inclined plates 32 are movably attached to the bottom of the two material control side frames 31, and arc-shaped pressure plates 33 are fixedly attached to the top of the two material control side frames 31. A feed channel 201 corresponding to the material control mechanism 3 is opened at the middle of one end of the molten tin tank 2. One end of the two material control side frames 31, the bottom support inclined plates 32, and the arc-shaped pressure plates 33 are movably attached to the feed channel 201. By setting the bottom support inclined plates 32, the glass solution can be introduced into the upper surface of the molten tin in the molten tin tank 2 through the feed channel 201 at a certain angle. The bottom support inclined plates 32 and the arc-shaped pressure plates 33 form a drain port near one end of the molten tin tank 2. A rotating shaft column 321 is integrally formed at the end of the bottom support inclined plates 32 near the molten tin tank 2. The rotating shaft column 321 is rotatably mounted on the two material control side frames 31, facilitating the operation of the bottom support inclined plates. The 32 rotates up and down on the two material control side frames 31. The arc-shaped pressure plate 33 has a liquid control groove 331 at one end near the molten tin tank 2. The liquid control rod 34 is movably locked in the liquid control groove 331. The bottom of the liquid control rod 34 has a flat groove 342. The two shaft ends of the liquid control rod 34 are fixedly installed with adjusting shafts 341. The adjusting shafts 341 are rotatably installed on the two material control side frames 31. By controlling the adjustment shafts 341 to rotate slowly, the liquid control rod 34 is rotated, and the size of the drain port is flexibly adjusted to facilitate precise control of the amount of glass solution flowing into the molten tin tank 2. The glass solution is spread evenly on the upper surface of the molten tin in an effective and accurate amount, and an ultra-thin glass liquid is formed on the upper surface of the molten tin, so that ultra-thin glass can be formed in the subsequent molding. With the synchronous traction of multiple traction mechanisms 24, an ultra-thin glass liquid is formed on the upper surface of the molten tin, and the temperature of the ultra-thin glass liquid gradually stabilizes and decreases uniformly when it flows on the upper surface of the molten tin.

[0047] A first gear 35 is fixedly installed at the end of the adjusting shaft 341. A drive shaft 351 is rotatably installed on the side of the material control frame 31 near the first gear 35. A second gear 352 is fixedly installed on the outside of the drive shaft 351. Multiple differential gears 353 are provided between the first gear 35 and the second gear 352. The multiple differential gears 353 are rotatably installed on the material control frame 31. Adjacent differential gears 353 are meshed. The end differential gears 353 are meshed with the corresponding first gear 35 and second gear 352, respectively. A second motor 354 is fixedly installed on the outer wall of the material control frame 31 near the drive shaft 351. The drive end of the second motor 354 is fixedly installed with the shaft end of the drive shaft 351. When the second motor 354 is turned on, the drive shaft 351 is controlled to drive the second gear 352 to rotate. With the meshing connection of the multiple differential gears 353 and the first gear 35, the adjusting shaft 341 is driven to rotate slowly.

[0048] A control shaft 322 is fixedly installed at the end of the bottom support inclined plate 32 away from the rotating shaft column 321. An arc-shaped through groove 3221 corresponding to the control shaft 322 is opened on the material control side frame 31. The control shaft 322 is movably engaged in the corresponding arc-shaped through groove 3221. A third rotating seat 36 is fixedly installed at the shaft end of the control shaft 322. A second telescopic cylinder 361 is provided at the top of the third rotating seat 36. The drive end of the second telescopic cylinder 361 is fixedly installed with the third rotating seat 36. A fourth rotating cylinder is fixedly installed at the top of the second telescopic cylinder 361. The fourth rotating seat 362 has a second rotating pin 363 rotatably mounted in the middle. The second rotating pin 363 is fixedly installed on the outside of the material control side frame 31. By controlling the opening of the second telescopic cylinder 361 to extend or retract, the control shaft 322 slides in the arc-shaped through groove 3221, thereby controlling the bottom support inclined plate 32 to rotate around the rotating pin 321. The tilt angle of the bottom support inclined plate 32 can be flexibly adjusted, thereby flexibly adjusting the angle at which the glass solution is introduced into the tin bath 2, so as to better form ultra-thin glass on the upper surface of the tin bath.

[0049] The pressure mechanism 5 includes a bottom support 51 and a top pressure component 52. The top pressure component 52 is located above the bottom support 51. The bottom support 51 includes two symmetrically distributed bottom support rollers 511, which are rotatably mounted on the molten tin tank 2. A bottom support belt 512 is movably sleeved on the outer side of the two bottom support rollers 511. The bottom support belt 512 is horizontally arranged. The top pressure component 52 includes two symmetrically distributed top pressure rollers 521, and a top pressure belt 522 is movably sleeved on the outer side of the two top pressure rollers 521. The top pressure belt 522 is inclined. One top pressure roller 521 is rotatably mounted on the molten tin tank 2. A drive sleeve 55 is rotatably fitted onto the end of the other top pressure roller 521. A shielding frame 551 is integrally formed on the opposite ends of each drive sleeve 55. A transmission gear 53 is fixedly mounted on the ends of the bottom support roller 511 and the top pressure roller 521, located away from the drive sleeve 55. The two transmission gears 53 mesh with each other. The distance between the bottom support strip 512 and the top pressure strip 522 at the ends of the bottom support member 51 and the top pressure member 52 away from the transmission gear 53 is defined as the rolling gap. A first motor 54 is located at the end of the bottom support roller 511, near the drive sleeve 55. The first motor 54 is fixedly installed on the outside of the molten tin tank 2. The drive end of the first motor 54 is fixedly installed at the end of the corresponding bottom support roller 511. By controlling the first motor 54 to turn the corresponding bottom support roller 511, and cooperating with the meshing connection of two transmission gears 53, the corresponding top pressure roller 521 is driven to rotate synchronously in the opposite direction. This, in turn, controls the bottom support belt 512 and the top pressure belt 522 to be synchronously transported in the opposite direction, thus transporting the ultra-thin molten glass. In the first L-shaped partition 21, the molten tin flows and is transported on the upper surface. It passes between the bottom support belt 512 and the top pressure belt 522. Because the top pressure belt 522 is inclined and works in sync with the bottom support belt 512 and the top pressure belt 522 to transport the molten tin in the opposite direction, the bottom support belt 512 and the top pressure belt 522 gradually roll and thin the front end of the molten tin again. This makes the molten tin flow even thinner on the upper surface of the molten tin in the second L-shaped partition 22 to continue to flow and be transported and cooled, thereby forming an even thinner molten tin to form molten tin and thus forming molten tin.

[0050] An arc-shaped adjustment groove 203 is provided on the side of the molten solder tank 2 near the drive sleeve 55. The drive sleeve 55 is movably engaged in the corresponding arc-shaped adjustment groove 203, allowing it to slide within the groove. A blocking frame 551 blocks the arc-shaped adjustment groove 203. While the drive sleeve 55 slides within the arc-shaped adjustment groove 203, the blocking frame 551 consistently blocks the groove, preventing molten solder from overflowing. A blocking groove 204 corresponding to the blocking frame 551 is provided at the inner end of the arc-shaped adjustment groove 203. The blocking frame 551 is movably engaged in the corresponding blocking groove 204. While the drive sleeve 55 slides within the arc-shaped adjustment groove 203, the blocking frame 551 slides within the blocking groove 204. The end of the drive sleeve 55 furthest from the blocking frame 551 extends out of the molten solder tank. A first rotating seat 56 is rotatably mounted on the outside of the tin tank 2. A first telescopic cylinder 561 is provided at the top of the first rotating seat 56. The drive end of the first telescopic cylinder 561 is fixedly mounted to the first rotating seat 56. A second rotating seat 57 is fixedly mounted at the top of the first telescopic cylinder 561. A first rotating pin 571 is rotatably mounted in the middle of the second rotating seat 57. The first rotating pin 571 is fixedly mounted on the top of the outside of the tin tank 2. By controlling the extension and retraction of the first telescopic cylinder 561, the drive sleeve 55 is controlled to slide in the arc-shaped adjustment groove 203, thereby controlling the top pressing component 52 to rotate around one of the top pressing rollers 521 as the axis. The tilt angle of the top pressing component 52 is adjusted, thereby flexibly adjusting the length of the rolling gap so as to roll out an ultra-thin glass liquid of appropriate thickness according to the requirements, improving the flexibility of the entire device.

When the molten solder level is high, it is necessary to lower the liquid level by controlling the start of the bidirectional hydraulic pump 62. The molten solder in the molten solder tank 2 is then guided into the storage tank 61 for buffering through multiple connecting clamps 632, multiple guide branches 631, a main guide pipe 63, and a guide head 611, thereby lowering the molten solder level. When the molten solder level in the molten solder tank 2 is low, it is necessary to raise the liquid level by controlling the start of the bidirectional hydraulic pump 62. The molten solder buffered in the storage tank 61 is then guided into the molten solder tank 2 through the guide head 611, the main guide pipe 63, multiple guide branches 631, and multiple connecting clamps 632, thereby raising the molten solder level. This allows for flexible adjustment of the molten solder level so that the ultra-thin glass melt can flow and spread on the surface of the molten solder.

[0053] The unloading mechanism 4 includes an unloading inclined frame 41. The molten tin tank 2 has an unloading groove 202 corresponding to the unloading mechanism 4 at the middle of the end away from the material control mechanism 3. One end of the unloading inclined frame 41 is fixedly engaged in the unloading groove 202. The bottom inner side of the unloading inclined frame 41 is provided with a plurality of evenly distributed electric guide rollers 42. The plurality of electric guide rollers 42 are inclined. The thinner ultra-thin glass liquid is introduced into the unloading inclined frame 41 through the unloading groove 202. With the control of opening the plurality of electric guide rollers 42, the thinner ultra-thin glass liquid is tilted and discharged from the molten tin tank 2 for subsequent annealing treatment.

[0054] A manufacturing process for an ultrathin photovoltaic glass production apparatus includes the following steps:

[0055] Step 1: Place the molten tin above the first L-shaped partition 21 and the second L-shaped partition 22. By setting up multiple heating modules 23 distributed in a rectangular array, the molten tin can be temperature controlled in a rectangular array, thereby precisely controlling the temperature of each area of ​​the molten tin. And by using multiple traction mechanisms 24, the glass solution flowing on the surface of the molten tin is stretched and pulled to make the glass solution ultra-thin.

[0056] According to the thinness requirements of photovoltaic glass, the second telescopic cylinder 361 is opened to extend or retract, which drives the control shaft 322 to slide in the arc-shaped groove 3221, thereby controlling the bottom support inclined plate 32 to rotate with the rotating shaft 321, flexibly adjusting the tilt angle of the bottom support inclined plate 32, thereby flexibly adjusting the angle at which the glass solution is introduced into the tin liquid tank 2.

[0057] And by controlling the opening of the first telescopic cylinder 561 to extend and retract, the drive sleeve 55 slides in the arc-shaped adjustment groove 203, thereby controlling the top pressure member 52 to rotate around one of the top pressure rollers 521 as the axis, adjusting the tilt angle of the top pressure member 52, thereby flexibly adjusting the length of the rolling gap, so as to roll out an ultra-thin glass liquid of appropriate thickness according to the requirements.

[0058] Step 2: The mixed molten glass solution is introduced into the upper surface of the molten tin tank 2 at a certain angle through the feed channel 201. During this process, the second motor 354 is activated to control the drive shaft 351 to drive the second gear 352 to rotate. In conjunction with the meshing connection of multiple differential gears 353 and the first gear 35, the adjusting shaft 341 is driven to rotate slowly, which drives the liquid control rod 34 to rotate. The size of the drain port is flexibly adjusted to accurately control the amount of glass solution flowing into the molten tin tank 2, so that the glass solution is spread evenly on the upper surface of the molten tin in an effective and accurate manner, forming an ultra-thin layer of glass liquid on the upper surface of the molten tin, so as to form ultra-thin glass in the subsequent molding. With the synchronous traction of multiple traction mechanisms 24, an ultra-thin layer of glass liquid is formed on the upper surface of the molten tin, and the temperature of the ultra-thin glass liquid gradually stabilizes and decreases uniformly as it flows on the upper surface of the molten tin.

[0059] During this process, when the molten tin level in the molten tin tank 2 is high, the level needs to be lowered. The bidirectional hydraulic pump 62 is activated to guide the molten tin in the molten tin tank 2 into the storage tank 61 for buffering through multiple connecting clamps 632, multiple guide branches 631, a main guide pipe 63, and a guide head 611, thereby lowering the molten tin level. When the molten tin level in the molten tin tank 2 is low, the level needs to be raised. The bidirectional hydraulic pump 62 is activated to guide the molten tin buffered in the storage tank 61 into the molten tin tank 2 through the guide head 611, the main guide pipe 63, multiple guide branches 631, and multiple connecting clamps 632, thereby raising the molten tin level. This allows for flexible adjustment of the molten tin level so that the ultra-thin glass melt can flow and spread on the surface of the molten tin.

[0060] Step 3: Control the first motor 54 to drive the corresponding bottom support roller 511 to rotate. With the meshing connection of the two transmission gears 53, drive the corresponding top pressure roller 521 to rotate synchronously in the opposite direction. Then control the bottom support belt 512 and the top pressure belt 522 to transmit synchronously in the opposite direction. The ultra-thin glass liquid flows and is transmitted on the upper surface of the molten tin in the first L-shaped partition 21. It passes between the bottom support belt 512 and the top pressure belt 522. Due to the inclined setting of the top pressure belt 522 and the synchronous reverse transmission of the bottom support belt 512 and the top pressure belt 522, the bottom support belt 512 and the top pressure belt 522 gradually roll and thin the front end of the ultra-thin glass liquid again, so that the ultra-thin glass liquid flows even thinner on the upper surface of the molten tin in the second L-shaped partition 22 to continue to flow, transmit and cool, thereby forming an even thinner ultra-thin glass liquid, so as to form ultra-thin glass.

[0061] Step 4: The thinner ultra-thin glass melt is introduced into the unloading inclined frame 41 through the unloading groove 202. With the control of multiple electric guide rollers 42, the thinner ultra-thin glass melt is tilted upward and discharged from the tin melt tank 2 for subsequent annealing treatment.

A production process using the production apparatus for ultra-thin photovoltaic glass as described in claim 8, characterized in that, Includes the following steps: Step 1: Place the molten tin above the first L-shaped partition (21) and the second L-shaped partition (22). By setting up multiple heating modules (23) distributed in a rectangular array, the molten tin can be temperature controlled in a rectangular array, thereby precisely controlling the temperature of each area of ​​the molten tin. And by using multiple traction mechanisms (24), the glass solution flowing on the surface of the molten tin is stretched and pulled to make the glass solution ultra-thin. According to the thinness requirements of photovoltaic glass, the second telescopic cylinder (361) is opened to extend or retract, which drives the control shaft (322) to slide in the arc groove (3221), thereby controlling the bottom support inclined plate (32) to rotate with the rotating shaft (321), flexibly adjusting the tilt angle of the bottom support inclined plate (32), thereby flexibly adjusting the angle at which the glass solution is introduced into the tin liquid tank (2); And by controlling the opening of the first telescopic cylinder (561) to extend and retract, the drive sleeve (55) slides in the arc-shaped adjustment groove (203), thereby controlling the top pressure member (52) to rotate around one of the top pressure rollers (521) as the axis, adjusting the tilt angle of the top pressure member (52), thereby flexibly adjusting the length of the rolling gap, so as to roll out an ultra-thin glass liquid of appropriate thickness according to the requirements; Step 2: The mixed molten glass solution is introduced into the upper surface of the molten tin in the molten tin tank (2) at a certain angle through the feed channel (201). During this process, the second motor (354) is turned on to control the drive shaft (351) to drive the second gear (352) to rotate. With the meshing connection of multiple differential gears (353) and the first gear (35), the adjustment shaft (341) is driven to rotate slowly, which drives the liquid control rod (34) to rotate. The size of the drain port is flexibly adjusted to facilitate precise control of the amount of glass solution flowing into the molten tin tank (2), so that the glass solution is spread evenly on the upper surface of the molten tin in an effective and accurate amount, and an ultra-thin glass liquid is formed on the upper surface of the molten tin, so that ultra-thin glass can be formed in the future. With the synchronous traction of multiple traction mechanisms (24), an ultra-thin glass liquid is formed on the upper surface of the molten tin, and the temperature of the ultra-thin glass liquid gradually stabilizes and decreases uniformly when it flows on the upper surface of the molten tin. During this process, when the molten tin level in the molten tin tank (2) is high, it is necessary to lower the molten tin level by controlling the start of the bidirectional hydraulic pump (62) to guide the molten tin in the molten tin tank (2) into the storage tank (61) through multiple connecting clamps (632), multiple liquid guide branches (631), and liquid guide main pipe (63) and liquid guide head (611), thereby lowering the molten tin level. When the molten tin level in the molten tin tank (2) is low, it is necessary to raise the molten tin level by controlling the start of the bidirectional hydraulic pump (62) to guide the molten tin buffered in the storage tank (61) into the molten tin tank (2) through the liquid guide head (611), liquid guide main pipe (63), multiple liquid guide branches (631) and multiple connecting clamps (632), thereby raising the molten tin level.

It passes between the bottom support belt (512) and the top pressure belt (522). Due to the inclined setting of the top pressure belt (522) and the synchronous reverse transmission of the bottom support belt (512) and the top pressure belt (522), the bottom support belt (512) and the top pressure belt (522) gradually roll and thin the front end of the ultra-thin glass liquid again, so that the ultra-thin glass liquid flows even thinner on the upper surface of the molten tin in the second L-shaped partition (22) to continue to flow and be cooled, thereby forming an even thinner ultra-thin glass liquid, so as to form ultra-thin glass.
