Description

Technical Field

[0001] The present invention relates to the field of glass forming equipment, and particularly to a pulling edge mechanism for ultra-thin flexible glass. Background Art

[0002] During the production and manufacturing process of flat glass, a pulling edge machine is required to traction the edge of the molten glass plate to prevent the flat glass from shrinking towards the center of the flat glass due to the action of surface tension.

[0003] A Chinese published document (CN106495451B) discloses a pulling edge mechanism for ultra-thin flexible glass. In this document, a cooling air duct is used to cool the machine head and the machine rod, a heating element is used to make up for the heat taken away by the machine head, a temperature measuring element can be used to detect the ambient temperature around the glass plate in real time, and the heating power of the heating element and the ventilation volume in the cooling air duct can be adjusted in time according to the measured temperature, so as to accurately control the temperature drop rate of the glass plate at the contact with the machine head, reduce the temperature difference between the glass plate at the contact with the machine head and other parts of the glass plate, and make the glass plate at the contact with the machine head just in the appropriate viscosity range (10-10 dPa·s) for thinning, which can effectively avoid the occurrence of deformation, warping and other phenomena caused by too large temperature difference between the clamped part and the middle part of the glass plate. Moreover, the cooling air duct is used to send cold air into the machine head and the machine rod to reduce the temperature of the machine head and the machine rod, avoid the influence of too high temperature on the normal use of the machine head and the machine rod, and extend the service life of the machine head and the machine rod;

[0004] In the above solution, both the machine head and the machine rod are designed to be hollow, and the two are butt-jointed and assembled together, and the cooling structure is placed in the cavity between the two. Although there is a cooling structure operating inside the machine head and the machine rod to play a role in cooling and protecting the two, at the butt-joint of the machine head and the machine rod, the wall thickness of the structure is different, and the flow path of the cooling gas cannot be guaranteed to be very smooth. If gas convection occurs in the cavity (when the high-temperature gas is discharged, it will change its path due to the obstruction of the structure in the cavity. If the changed path conflicts with the discharged path, convection will occur), it will affect the discharge efficiency of the high-temperature gas, and still cause the temperature of the machine head and the machine rod to be too high, thereby reducing the service life of the machine head and the machine rod. Summary of the Invention

[0005] The purpose of the present invention is to provide a pulling edge mechanism for ultra-thin flexible glass to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: An ultra-thin flexible glass edge pulling mechanism, comprising: two docking rod bodies symmetrically distributed, with edge pulling wheels threadedly assembled at the same-side ends of the two docking rod bodies. On the mutually remote sides of the two docking rod bodies, there are gear differentials, and the gear differentials are located at the ends of the docking rod bodies remote from the edge pulling wheels. A support frame rotatably sleeved on the surface of the docking rod body is fixedly arranged on the side wall of the gear differential. Transmission gears are fixedly assembled between the output end of the gear differential and the outer wall of the docking rod body, and two adjacent transmission gears mesh with each other. A slide rail is placed at the bottom of the two gear differentials, and a slide rail block slidably fitted inside the slide rail is fixedly arranged at the bottom of each gear differential. An oppositely threaded screw rod is rotatably assembled inside the slide rail, and the two slide rail blocks are threadedly assembled at both ends of the oppositely threaded screw rod;

[0007] It further comprises: a reflux heat dissipation unit, which causes the flowing gas to reflux and discharge inside the docking rod body and the edge pulling wheel, and dissipates the heat;

[0008] A temperature reduction protection unit, which is used to inject cold air into the docking rod body and the edge pulling wheel to prevent the docking rod body and the edge pulling wheel from being damaged due to excessive high temperature. The temperature reduction protection unit is located on the sides of the two docking rod bodies remote from the edge pulling wheels;

[0009] The ultra-thin glass is clamped and pulled between the two edge pulling wheels, and there is a heating plate on the sides of the two edge pulling wheels remote from the ultra-thin glass. The heating plate is used to prevent the temperature difference between the clamped part and the middle part of the ultra-thin glass from being too large, mainly playing a role of constant temperature.

[0010] Preferably, the docking rod body and the edge pulling wheel are both hollow, and the end of the edge pulling wheel remote from the docking rod body is a closed end. The reflux heat dissipation unit includes an extension tube and a flared tube respectively placed inside the docking rod body and the edge pulling wheel, and the mutually approaching ends of the extension tube and the flared tube are butted. The distance between the edge pulling wheel and the flared tube is the same as the distance between the extension tube and the docking rod body. A reflux cavity is formed between the extension tube and the flared tube and the docking rod body and the edge pulling wheel. The end of the extension tube remote from the flared tube extends out of the docking rod body. The closed end of the edge pulling wheel is provided with an inner conical part, and the end of the flared tube remote from the extension tube is placed outside the inner conical part. The docking rod body and the edge pulling wheel and the extension tube and the flared tube are coaxially installed. The design of the inner conical part can ensure that the cold air entering the flared tube through the extension tube can be quickly diffused into the reflux cavity under the action of the inner conical part, thereby ensuring the smoothness of gas flow and avoiding the situation of gas convection.

[0011] Preferably, the cooling protection unit includes a sealing frame body located on the side of the two docking rod bodies away from the edge pulling wheel, and the position of the sealing frame body is relatively fixed with respect to the slide rail. A suction pump is fixedly installed on the top of the sealing frame body, and at least half of the capacity of the cooling liquid is injected into the sealing frame body. The input end of the suction pump is fixedly equipped with an air suction pipe, and the air suction pipe is fixedly extended into the sealing frame body, and the port of the air suction pipe is suspended at the inner top of the sealing frame body. The output end of the suction pump is fixedly connected with a first exhaust pipe. Each end of the extension pipe away from the flared pipe is fixedly equipped with a second exhaust pipe, and the two second exhaust pipes are fixedly docked with the exposed end of the first exhaust pipe through a tee docking pipe. An air inlet pipe is also fixedly inserted into the sealing frame body. The upper end of the air inlet pipe extends out of the sealing frame body, and the bottom of the air inlet pipe is placed in the cooling liquid inside the sealing frame body. The suction pump sucks the air inside the sealing frame body through the air suction pipe, and the outside gas replenishes the air inside the sealing frame body through the air inlet pipe. During the filling process, the outside gas will pass through the cooling liquid, such as water. The outside gas can absorb a certain amount of heat by the cooling liquid, thereby forming cold air. Moreover, a micro-refrigerator can be placed in the lower part of the sealing frame body, and by controlling the operating state of the micro-refrigerator, the temperature of the cooling liquid can be adjusted.

[0012] Preferably, both the first exhaust pipe and the second exhaust pipe are made of silica gel material. The first exhaust pipe and the second exhaust pipe made of silica gel material have a certain deformation ability and low heat conduction efficiency.

[0013] Preferably, a cleaning unit is also installed outside the docking rod body. The cleaning unit is used to remove the impurities carbonized on the surface of the edge pulling wheel due to high temperature. The cleaning unit includes a special-shaped converging cylinder fixedly sleeved on the outer surface of the end of the extension pipe away from the flared pipe, and the special-shaped converging cylinder also rotatably wraps around the outer surface of the docking rod body. The special-shaped converging cylinder is docked with the end of the reflux cavity away from the edge pulling wheel. The end of the special-shaped converging cylinder close to the edge pulling wheel is an eccentric conical port, and an extension pipe is fixedly connected and assembled at the conical port. The axes of the extension pipe and the docking rod body are parallel, and the end face of the extension pipe away from the special-shaped converging cylinder faces the arc surface of the edge pulling wheel. During the process of the edge pulling wheel pulling the ultra-thin glass, its working temperature is relatively high. If dust impurities or oxides adhere to its surface, they will be carbonized, thereby forming a carbonized impurity layer.

[0014] Preferably, an auxiliary unit is further provided inside the sealing frame body. The auxiliary unit is used to improve the effect of the impurity removal unit in removing carbonized impurities. The auxiliary unit includes a receiving cylinder fixedly assembled at one end of the air extraction pipe away from the air extraction pump, and the lower end surface of the air extraction pipe does not contact the receiving cylinder. The end of the air inlet pipe extending into the coolant is vertical, and the vertical end of the air inlet pipe is closed. A plurality of air holes are formed on the outer surface of the vertical end of the air inlet pipe. A right-angle adapter tube is coaxially sleeved outside the vertical end of the air inlet pipe. The other end of the right-angle adapter tube bends away from the air extraction pump. A delivery pipe stands inside the sealing frame body. The end of the right-angle adapter tube away from the air inlet pipe is fixedly docked with the bottom of the delivery pipe. The upper end of the delivery pipe is in the shape of an elbow, and the upper port of the delivery pipe bends downward. A docking plate is fixedly sleeved on the outer surface of the vertical end of the air inlet pipe, and the air holes are located at one end of the docking plate facing the right-angle adapter tube. A displacement component is further provided on the outer surface of the delivery pipe, and a one-way valve is provided at the connection between the first exhaust pipe and the three-way docking pipe. The one-way valve only allows the fluid in the first exhaust pipe to transport towards the two second exhaust pipes.

[0015] Preferably, the displacement component includes a sliding block fixedly sleeved on the outer surface of the delivery pipe. Two optical axes are slidably inserted inside the sliding block. Both ends of the optical axes are fixed to the sealing frame body. A spring is fixedly provided between each sliding block away from the air inlet pipe and the docking rod body, and the two springs are respectively sleeved outside the two optical axes. A driving motor is fixedly installed at the bottom of the sealing frame body, and the output end of the driving motor rotates and is embedded inside the sealing frame body. Two turntables are fixedly sleeved on the output end of the driving motor, and the turntables are located on the side of the sliding block away from the spring. A cam is fixedly provided between the two turntables. A column is also fixedly provided at the end of the sliding block close to the cam. An arc portion is provided at the eccentric end of the cam, and the outer diameter of the arc portion is the same as the outer diameter of the turntable. When the driving motor drives the two turntables to drive the cam to rotate, the sliding block and the delivery pipe can be moved so that the right-angle adapter tube abuts against the docking plate, and the upper port of the delivery pipe is placed above the receiving cylinder.

[0016] Preferably, the end of the extension pipe close to the edge pulling wheel is closed. Strip-shaped exhaust slits are formed on the outer surface of the extension pipe, and the orientation of the exhaust slits is tangent to the arc surface of the edge pulling wheel. When high-speed hot air flow is discharged through the exhaust slits, the carbonized impurities attached to the surface of the edge pulling wheel can be blown off.

[0017] Preferably, the inner diameter of the right-angle adapter tube is larger than the outer diameter of the air inlet pipe, which ensures that there is a large space between the right-angle adapter tube and the air inlet pipe.

[0018] Preferably, a receiving ring groove is formed at one end of the docking plate close to the right-angle adapter tube. The receiving ring groove is used for docking with the end of the right-angle adapter tube, and a silica gel gasket ring is fixedly arranged at the exposed end of the right-angle adapter tube. Through the action of the silica gel gasket ring and the receiving ring groove, the sealing performance when the right-angle adapter tube is docked with the docking plate can be ensured.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] During the traction operation of the ultra-thin glass in a molten state by the docking rod body and the edge pulling wheel, the present invention can inject cold air into their interiors through the temperature reduction protection unit, and quickly take out part of the heat through the reflux heat dissipation unit. The edge pulling wheel and the docking rod body are cooled by the way of reflux heat exchange, so as to prevent the docking rod body and the edge pulling wheel from being overheated during operation and affecting their normal service lives.

Detailed implementation mode

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figures 1-6 , a kind of edge pulling mechanism for ultra-thin flexible glass in the figure, including: two docking rod bodies 1 distributed symmetrically, edge pulling wheels 2 are threadedly assembled at the same-side ends of the two docking rod bodies 1, gear differentials 3 are arranged on the mutually remote sides of the two docking rod bodies 1, and the gear differential 3 is located at the end of the docking rod body 1 far from the edge pulling wheel 2. A support frame 4 rotatably sleeved on the surface of the docking rod body 1 is fixedly arranged on the side wall of the gear differential 3. Transmission gears 5 are fixedly assembled between the output end of the gear differential 3 and the outer wall of the docking rod body 1, and two adjacent transmission gears 5 are meshed with each other. A slide rail 6 is placed at the bottom of the two gear differentials 3, and a slide rail block slidably embedded in the slide rail 6 is fixedly arranged at the bottom of each gear differential 3. An oppositely threaded rod is rotatably assembled in the slide rail 6, and the two slide rail blocks are threadedly assembled at both ends of the oppositely threaded rod;

[0031] It also includes: a reflux heat dissipation unit, which promotes the reflux and discharge of the flowing gas inside the docking rod body 1 and the edge pulling wheel 2 and dissipates the heat;

[0032] A temperature reduction protection unit is used to inject cold air into the docking rod body 1 and the edge pulling wheel 2 to prevent the docking rod body 1 and the edge pulling wheel 2 from being damaged due to excessive high temperature. The temperature reduction protection unit is located on the side of the two docking rod bodies 1 far from the edge pulling wheel 2;

[0033] The ultra-thin glass is clamped and pulled between the two edge pulling wheels 2, and there is a heating plate on the side of the two edge pulling wheels 2 far from the ultra-thin glass. The heating plate is used to prevent the temperature difference between the clamped part and the middle part of the ultra-thin glass from being too large, mainly playing a role of constant temperature.

[0034] Both the docking rod body 1 and the edge pulling wheel 2 are hollow, and one end of the edge pulling wheel 2 away from the docking rod body 1 is a closed end. The reflux heat dissipation unit includes an extension pipe 7 and a flared pipe 8 respectively placed inside the docking rod body 1 and the edge pulling wheel 2, and the ends of the extension pipe 7 and the flared pipe 8 close to each other are docked. The distance between the edge pulling wheel 2 and the flared pipe 8 is the same as the distance between the extension pipe 7 and the docking rod body 1. A reflux cavity is formed between the extension pipe 7 and the flared pipe 8 and the docking rod body 1 and the edge pulling wheel 2. One end of the extension pipe 7 away from the flared pipe 8 extends out of the docking rod body 1. An inner conical part 9 is provided at the closed end of the edge pulling wheel 2, and one end of the flared pipe 8 away from the extension pipe 7 is placed outside the inner conical part 9. The docking rod body 1 and the edge pulling wheel 2 and the extension pipe 7 and the flared pipe 8 are coaxially installed. The design of the inner conical part 9 can ensure that the cold air entering the flared pipe 8 through the extension pipe 7 can be quickly diffused into the reflux cavity under the action of the inner conical part 9, so as to ensure the smoothness of gas flow and avoid the occurrence of gas convection.

[0035] The temperature reduction protection unit includes a sealed frame body 12 located on one side of the two docking rod bodies 1 away from the edge pulling wheel 2, and the position of the sealed frame body 12 is relatively fixed with respect to the slide rail 6. A suction pump 14 is fixedly installed on the top of the sealed frame body 12, and at least one-half of the capacity of the cooling liquid is injected into the sealed frame body 12. The input end of the suction pump 14 is fixedly equipped with an air suction pipe 15, and the air suction pipe 15 is fixedly extended into the sealed frame body 12, and the port of the air suction pipe 15 is suspended on the inner top of the sealed frame body 12. The output end of the suction pump 14 is fixedly connected with a first exhaust pipe 17. Each end of the extension pipe 7 away from the flared pipe 8 is fixedly equipped with a second exhaust pipe 18, and the exposed ends of the two second exhaust pipes 18 and the first exhaust pipe 17 are fixedly docked through a tee joint pipe 16. An air inlet pipe 13 is also fixedly inserted into the sealed frame body 12. The upper end of the air inlet pipe 13 extends out of the sealed frame body 12, and the bottom of the air inlet pipe 13 is placed in the cooling liquid inside the sealed frame body 12. The suction pump 14 sucks the air inside the sealed frame body 12 through the air suction pipe 15, and the outside gas replenishes the air inside the sealed frame body 12 through the air inlet pipe 13. During the filling process, the outside gas will pass through the cooling liquid, such as water. The outside gas can absorb a certain amount of heat by the cooling liquid, thereby forming cold air. Moreover, a micro-refrigerator can be placed in the lower part of the sealed frame body 12, and the temperature of the cooling liquid can be adjusted by controlling the operating state of the micro-refrigerator.

[0036] Both the first exhaust pipe 17 and the second exhaust pipe 18 are made of silica gel material. The first exhaust pipe 17 and the second exhaust pipe 18 made of silica gel material have a certain deformation ability and low heat conduction efficiency.

[0037] An impurity removal unit is also installed outside the docking rod body 1. The impurity removal unit is used to remove the impurities carbonized on the surface of the edge pulling wheel 2 due to high temperature. The impurity removal unit includes a special-shaped converging cylinder body 10 fixedly sleeved on the outer surface of the end of the extension pipe 7 away from the flared pipe 8, and the special-shaped converging cylinder body 10 also rotatably wraps around the outer surface of the docking rod body 1. The special-shaped converging cylinder body 10 is docked with one end of the return cavity away from the edge pulling wheel 2. One end of the special-shaped converging cylinder body 10 close to the edge pulling wheel 2 is an eccentric conical port, and an extension pipe 11 is fixedly connected and assembled at the conical port. The axes of the extension pipe 11 and the docking rod body 1 are parallel, and one end surface of the extension pipe 11 away from the special-shaped converging cylinder body 10 faces the arc surface of the edge pulling wheel 2. During the traction work of the edge pulling wheel 2 on the ultra-thin glass, its working temperature is relatively high. If dust impurities or oxides adhere to its surface, they will be carbonized, thus forming a carbonized impurity layer.

[0038] Working principle: When the docking rod body 1 and the edge pulling wheel 2 are used to perform edge pulling and traction treatment on the molten ultra-thin glass, in order to prevent the docking rod body 1 and the edge pulling wheel 2 from being damaged due to overheating, the suction pump 14 needs to be turned on during the working process. The suction pump 14 sucks the cold air inside the sealed frame body 12 through the suction pipe 15 and transports it to the extension pipe 7. The cold air flows towards the flared pipe 8 through the extension pipe 7, and under the action of the inner cone part 9, it quickly and smoothly diffuses towards the hollow cavity, and finally discharges towards one end of the hollow cavity away from the edge pulling wheel 2. During the process of the cold air flowing back, it can absorb the heat of the docking rod body 1 and the edge pulling wheel 2 and dissipate it to the outside, thus preventing the docking rod body 1 and the edge pulling wheel 2 from being prone to overheating during work, resulting in a short service life. In this solution, through the guidance of the inner cone part 9 on the gas, the situation of gas convection can be effectively avoided, thus ensuring that the gas can quickly and smoothly discharge through the hollow cavity.

[0039] In this solution, it is also considered that the surface of the edge pulling wheel 2 is prone to adhering to dust impurities in the air, and when the edge pulling wheel 2 is not in use, its surface will also be oxidized. The oxidized substances and dust impurities will gradually be carbonized during the heating process of the edge pulling wheel 2, thus forming carbonized impurities and adhering to the surface of the edge pulling wheel 2. When the edge pulling wheel 2 clamps and traction the molten ultra-thin glass, it is easy for the carbonized impurities to stick to the clamped part of the ultra-thin glass, thus increasing the defective rate after the ultra-thin glass is formed. For this reason, in this solution, the hot air flow discharged from the hollow cavity will be converged by the special-shaped converging cylinder body 10 and directly discharged towards the surface of the edge pulling wheel 2 through the guidance of the extension pipe 11. When the high-speed hot air flow flushes the surface of the edge pulling wheel 2 through the port of the extension pipe 11, the carbonized impurities adhering to its surface can be loosened and fallen off.

[0040] The edge pulling wheel 2 used in this solution is a common wheel body, that is, made of carbon steel alloy.

[0041] Embodiment Two: Please refer toFigures 2-5 , this embodiment is a further illustration of Embodiment 1. An auxiliary unit is also provided inside the sealing frame 12. The auxiliary unit is used to improve the effect of the impurity removal unit in removing carbonized impurities. The auxiliary unit includes a receiving cylinder 21 fixedly assembled at one end of the suction pipe 15 away from the suction pump 14, and the lower end surface of the suction pipe 15 does not contact the receiving cylinder 21. One end of the intake pipe 13 extending into the coolant is vertical, the vertical end of the intake pipe 13 is closed, and a plurality of air holes 33 are formed on the outer surface of the vertical end of the intake pipe 13. A right-angle adapter 26 is coaxially sleeved outside the vertical end of the intake pipe 13. The other end of the right-angle adapter 26 bends away from the suction pump 14. A delivery pipe 22 is also erected inside the sealing frame 12. The end of the right-angle adapter 26 away from the intake pipe 13 is fixedly docked with the bottom of the delivery pipe 22. The upper end of the delivery pipe 22 is in an elbow shape, and the upper port of the delivery pipe 22 bends downward. A docking plate 31 is fixedly sleeved on the outer surface of the vertical end of the intake pipe 13, and the air holes 33 are located at one end of the docking plate 31 facing the right-angle adapter 26. A displacement member is also provided on the outer surface of the delivery pipe 22, and a one-way valve 19 is provided at the connection between the first exhaust pipe 17 and the three-way docking pipe 16. Among them, the one-way valve 19 only allows the fluid in the first exhaust pipe 17 to transport towards the two second exhaust pipes 18.

[0042] The displacement member includes a sliding block 24 fixedly sleeved on the outer surface of the delivery pipe 22, and two optical axes 23 are slidably inserted inside the sliding block 24. Both ends of the optical axes 23 are fixed to the sealing frame 12. A spring 25 is fixedly provided between each sliding block 24 and the docking rod body 1 at the end away from the intake pipe 13, and the two springs 25 are respectively sleeved outside the two optical axes 23. A driving motor 20 is fixedly mounted on the bottom of the sealing frame 12, and the output end of the driving motor 20 rotates and is embedded inside the sealing frame 12. Two turntables 27 are fixedly sleeved on the output end of the driving motor 20, and the turntables 27 are located on the side of the sliding block 24 away from the spring 25. A cam 28 is also fixedly provided between the two turntables 27. A column 30 is also fixedly provided at the end of the sliding block 24 close to the cam 28. The eccentric end of the cam 28 is provided with an arc portion 29, and the outer diameter of the arc portion 29 is the same as the outer diameter of the turntable 27. When the driving motor 20 drives the two turntables 27 to drive the cam 28 to rotate, the sliding block 24 and the delivery pipe 22 can be moved, so that the right-angle adapter 26 abuts against the docking plate 31, and the upper port of the delivery pipe 22 is placed above the receiving cylinder 21.

[0043] The inner diameter of the right-angle adapter 26 is larger than the outer diameter of the intake pipe 13, that is, to ensure that there is a large space between the right-angle adapter 26 and the intake pipe 13.

[0044] One end of the docking plate 31 close to the right-angle adapter tube 26 is provided with a receiving annular groove 32 for docking with the end of the right-angle adapter tube 26. A silica gel gasket ring is fixedly arranged at the exposed end of the right-angle adapter tube 26. Through the action of the silica gel gasket ring and the receiving annular groove 32, the sealing performance when the right-angle adapter tube 26 is docked with the docking plate 31 can be ensured.

[0045] In this embodiment: When the suction pump 14 is running normally, the drive motor 20 simultaneously drives the turntable 27 and the cam 28 to rotate slowly. During the rotation, the cam 28 can push against the upright column 30 and the sliding block 24. The sliding block 24 drives the delivery pipe 22 and moves towards the Figure 2 direction of the intake pipe 13 in the figure. When the delivery pipe 22 is pushed and moved to the maximum distance, that is, the end of the right-angle adapter tube 26 abuts against the receiving annular groove 32, and the upper port of the delivery pipe 22 also moves directly above the receiving cylinder 21. Due to the function of the arc portion 29, the above state can be maintained for a short period of time. During this period, because the right-angle adapter tube 26 abuts against the docking plate 31 for sealing, the air entering through the intake pipe 13 and the air hole 33 can only remain inside the right-angle adapter tube 26. At this time, the suction pump 14 continuously sucks the gas inside the sealed housing 12, causing the air pressure inside the sealed housing 12 to decrease, while the gas pressure inside the right-angle adapter tube 26 remains unchanged. At this time, under the action of the pressure difference, the cooling liquid inside the right-angle adapter tube 26 can be injected into the receiving cylinder 21 through the delivery pipe 22, and the cooling liquid inside the receiving cylinder 21 can submerge the lower port of the suction pipe 15. At this time, the suction pump 14 will directly transport a small amount of the cooling liquid into the extension pipe 7 and the flared pipe 8. Since the temperature inside the flared pipe 8 is too high, the cooling liquid can be instantly vaporized. The vaporization will cause the air pressure inside the hollow cavity to increase, thereby increasing the discharge flow rate of the hot air flow at the exposed end of the extension pipe 11, and further increasing the cleaning effect on the carbonized impurities attached to the surface of the edge pulling wheel 2.

[0046] In this solution, the cooling liquid is water.

[0047] Embodiment Three: Please refer to Figure 6 and Figure 7 . This embodiment is a further description of Embodiments One and Two. One end of the extension pipe 11 close to the edge pulling wheel 2 is closed. The outer surface of the extension pipe 11 is provided with strip-shaped exhaust slits 34, and the orientation of the exhaust slits 34 is tangent to the arc surface of the edge pulling wheel 2. When high-speed hot air flow is discharged through the exhaust slits 34, the carbonized impurities attached to the surface of the edge pulling wheel 2 can be blown off.

[0048] In this embodiment: The extension tube 11 is located on the side of the edge roller 2 away from the ultra-thin glass, and the two are parallelly distributed. When the high-speed hot air flow in the extension tube 11 is discharged through the exhaust slit 34, the jet direction of the high-speed hot air flow is tangent to the edge roller 2, which can most effectively blow off the carbonized impurities attached to the surface of the edge roller 2, and the falling direction of the carbonized impurities is also away from the ultra-thin glass.
