Description

Technical Field

[0001] The invention relates to the field of glass forming equipment, in particular to an ultra-thin flexible glass edge pulling mechanism. Background Art

[0002] During the production process of flat glass, a stretching machine is required to pull the edge of the glass plate in a molten state to prevent the flat glass from shrinking toward the center of the flat glass due to surface tension.

[0003] A Chinese public document (CN106495451B) records an ultra-thin flexible glass edge drawing mechanism, in which a cooling air duct is used to cool the machine head and the machine rod, a heating element is used to compensate for the heat taken away by the machine head, and a temperature measuring element can be used to detect the ambient temperature around the glass plate in real time. The heating power of the heating element and the ventilation volume in the cooling air duct are timely adjusted according to the measured temperature, so that the temperature drop rate of the glass plate in contact with the machine head can be accurately controlled, and the temperature difference between the glass plate in contact with the machine head and other parts of the glass plate can be reduced, so that the glass plate in contact with the machine head is just in the viscosity range suitable for thinning (10-10dPa·s), which can effectively avoid the deformation and warping of the glass plate caused by the large temperature difference between the clamped part and the middle part of the glass plate. In addition, 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 normal use of the machine head and the machine rod affected by excessive temperature, and extend the service life of the machine head and the machine rod;

[0004] In the above scheme, the machine head and the machine rod are both hollow in design, and the two are butt-jointed and assembled together, and the cooling structure is placed in the cavity between the two. Although the cooling structure runs inside the machine head and the machine rod to provide cooling protection for both, the wall thickness of the structure at the joint of the machine head and the machine rod is different, and the flow path of the cooling gas cannot be guaranteed to be very smooth. If gas convection occurs in the cavity (the high-temperature gas will change its path when it is discharged due to obstruction by the structure in the cavity, and convection will occur if the changed path conflicts with the discharge path), it will affect the discharge efficiency of the high-temperature gas, and will 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.

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

[0033] The ultra-thin glass is clamped and pulled between the two edge-pulling wheels 2, and a heating plate is provided on the side of the two edge-pulling wheels 2 away from the ultra-thin glass. The heating plate is used to avoid excessive temperature difference between the clamped part and the middle part of the ultra-thin glass, and mainly plays a role in maintaining a constant temperature.

[0034] The docking rod body 1 and the edge wheel 2 are both hollow, and the end of the edge wheel 2 away from the docking rod body 1 is a closed end. The reflux heat dissipation unit includes an extension tube 7 and a flared tube 8 respectively placed inside the docking rod body 1 and the edge wheel 2, and the ends of the extension tube 7 and the flared tube 8 close to each other are docked, the spacing between the edge wheel 2 and the flared tube 8 is consistent with the spacing between the extension tube 7 and the docking rod body 1, and a reflux cavity is formed between the extension tube 7 and the flared tube 8 and the docking rod body 1 and the edge wheel 2, and the extension tube 7 is away from the flared tube 8.

[0035] The cooling protection unit includes a sealing frame 12 located on the side of the two docking rods 1 away from the edge pull wheel 2, and the position of the sealing frame 12 and the slide rail 6 is relatively fixed, a suction pump 14 is fixedly mounted on the top of the sealing frame 12, and at least one-half of the volume of cooling liquid is injected into the interior of the sealing frame 12, an exhaust pipe 15 is fixedly installed at the input end of the suction pump 14, the exhaust pipe 15 is fixedly extended into the interior of the sealing frame 12, and the port of the exhaust pipe 15 is suspended at the inner top of the sealing frame 12, an output end of the suction pump 14 is fixedly connected to a first exhaust pipe 17, and each extension pipe 7 is fixedly equipped with a second exhaust pipe 18 at one end away from the flaring pipe 8, and the two second exhaust pipes 18 are connected to the exposed end of the first exhaust pipe 17. The sealed frame 12 is fixedly connected by a three-way butt joint 16, and an air inlet pipe 13 is fixedly inserted inside the sealed frame 12. The upper end of the air inlet pipe 13 extends out of the sealed frame 12, and the bottom of the air inlet pipe 13 is placed in the internal cooling liquid of the sealed frame 12. The suction pump 14 sucks the air inside the sealed frame 12 through the suction pipe 15, and the outside gas replenishes the air inside the sealed frame 12 through the air inlet pipe 13. During the filling process, the outside gas will pass through the cooling liquid, such as water, and the outside gas can absorb a certain amount of heat by the cooling liquid, thereby forming cold air, and a micro refrigerator can be placed in the lower part of the sealed frame 12. By controlling the operating state of the micro refrigerator, the temperature of the coolant is adjusted.

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

[0037] A de-impurity unit is also mounted on the outside of the docking rod body 1, and the de-impurity unit is used to remove impurities carbonized on the surface of the edge drawing wheel 2 due to high temperature. The de-impurity unit includes a special-shaped converging cylinder 10 fixedly mounted on the outer surface of the end of the extension tube 7 away from the expanding tube 8, and the special-shaped converging cylinder 10 is also rotatably wrapped around the outer surface of the docking rod body 1, and the special-shaped converging cylinder 10 is docked with the end of the reflux cavity away from the edge drawing wheel 2. The end of the special-shaped converging cylinder 10 close to the edge drawing wheel 2 is an eccentric conical port, and an extension tube 11 is fixedly connected and installed at the conical port. The axes of the extension tube 11 and the docking rod body 1 are parallel, and the end face of the extension tube 11 away from the special-shaped converging cylinder 10 faces the arc surface of the edge drawing wheel 2. During the process of the edge drawing wheel 2 pulling the ultra-thin glass, its working temperature is relatively high. If dust, impurities or oxides are attached to its surface, they will be carbonized, thereby forming a carbonized impurity layer.

[0038] Working principle: When the ultra-thin glass in the molten state is subjected to the edge drawing and traction processing by the docking rod body 1 and the edge drawing wheel 2, in order to prevent the docking rod body 1 and the edge drawing wheel 2 from being damaged due to overheating, the suction pump 14 needs to be turned on during operation. The suction pump 14 draws the cold air inside the sealing frame 12 through the exhaust pipe 15 and transports it to the extension tube 7. The cold air flows toward the expansion tube 8 through the extension tube 7, and under the action of the inner cone 9, it quickly and smoothly diffuses into the hollow cavity, and finally is discharged toward the end of the hollow cavity away from the edge drawing wheel 2. During the reflux process, the cold air can absorb the heat of the docking rod body 1 and the edge drawing wheel 2, and dissipate it to the outside, thereby preventing the docking rod body 1 and the edge drawing wheel 2 from being easily overheated during operation, resulting in a short service life. In this scheme, the inner cone 9 guides the gas, which can effectively avoid convection of the gas, thereby ensuring that the gas can be discharged quickly and smoothly through the hollow cavity.

[0039] In the present scheme, it is also taken into consideration that the surface of the edge drawing wheel 2 is easily adhered to dust and impurities in the air, and the surface of the edge drawing wheel 2 will also be oxidized when not in use. The oxidizing substances and dust impurities will gradually carbonize during the heating process of the edge drawing wheel 2, thereby forming carbonized impurities and adhering to the surface of the edge drawing wheel 2. When the edge drawing wheel 2 clamps and pulls the ultra-thin glass in a molten state, the carbonized impurities are easily adhered to the clamped part of the ultra-thin glass, thereby increasing the defective rate of the ultra-thin glass after forming. For this reason, in the present scheme, the hot air flow discharged from the hollow cavity will be gathered by the special-shaped converging cylinder 10, and discharged directly toward the surface of the edge drawing wheel 2 through the guidance of the extension tube 11. When the high-speed hot air flow flushes the surface of the edge drawing wheel 2 through the port of the extension tube 11, the carbonized impurities adhering to its surface can be loosened and fall off.

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

[0041] Example 2: Please refer to Figure 2-Figure 5 , this embodiment is a further explanation of the first embodiment, an auxiliary unit is further provided inside the sealing frame 12, the auxiliary unit is used to improve the effect of the impurity removal unit on removing carbonized impurities, the auxiliary unit includes a receiving tube 21 fixedly mounted on an end of the exhaust pipe 15 away from the suction pump 14, and the lower end surface of the exhaust pipe 15 does not contact the receiving tube 21, the end of the intake pipe 13 extending into the cooling liquid is vertical, the vertical end of the intake pipe 13 is closed, and a plurality of air holes 33 are provided on the outer surface of the vertical end of the intake pipe 13, a right-angle adapter tube 26 is coaxially sleeved on the vertical end of the intake pipe 13, and the other end of the right-angle adapter tube 26 faces away from the suction pump 14. The air inlet pipe 13 is bent in the direction of the pump 14, and a delivery pipe 22 is also provided inside the sealing frame 12. The end of the right-angle adapter pipe 26 away from the air inlet pipe 13 is fixedly connected to the bottom of the delivery pipe 22. The upper end of the delivery pipe 22 is in the shape of an elbow, and the upper end of the delivery pipe 22 is bent downward. The outer surface of the vertical end of the air inlet pipe 13 is fixedly sleeved with a docking plate 31, and the air hole 33 is located at the end of the docking plate 31 facing the right-angle adapter pipe 26. A displacement component 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, wherein the one-way valve 19 only allows the fluid in the first exhaust pipe 17 to be transported toward the two second exhaust pipes 18.

[0042] The displacement component includes a sliding block 24 fixedly mounted on the outer surface of the delivery pipe 22, and two optical axes 23 are slidably inserted in the interior of the sliding block 24, and both ends of the optical axis 23 are fixed to the sealing frame 12. A spring 25 is fixedly arranged between the end of each sliding block 24 away from the air inlet pipe 13 and the docking rod body 1, and the two springs 25 are respectively sleeved on the outside of the two optical axes 23. A driving motor 20 is fixedly mounted at the bottom of the sealing frame 12, and the output end of the driving motor 20 is rotatably embedded in the interior of the sealing frame 12. The output end of the driving motor 20 is fixedly mounted with two The turntable 27 is located on the side of the sliding block 24 away from the spring 25. A cam 28 is fixedly arranged between the two turntables 27. A column 30 is fixedly arranged on the end of the sliding block 24 close to the cam 28. A circular arc portion 29 is arranged at the distal end of the cam 28, and the outer diameter of the circular arc portion 29 is consistent with the outer diameter of the turntable 27. When the driving motor 20 drives the two turntables 27 to rotate with the cam 28, the sliding block 24 and the conveying pipe 22 can be moved so that the right-angle transfer pipe 26 is against the docking plate 31, and the upper end of the conveying pipe 22 is placed above the receiving tube 21.

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

[0044] An accommodating ring groove 32 is provided at one end of the docking plate 31 close to the right-angle adapter tube 26. The accommodating ring groove 32 is used to dock with the end of the right-angle adapter tube 26, and a silicone gasket is fixedly provided at the exposed end of the right-angle adapter tube 26. Through the action of the silicone gasket and the accommodating ring groove 32, the sealing of the right-angle adapter tube 26 and the docking plate 31 can be ensured when docking.

[0045] In this embodiment, when the suction pump 14 is in normal operation, the driving motor 20 drives the rotating disk 27 and the cam 28 to rotate slowly. During the rotation, the cam 28 can push the column 30 and the sliding block 24, and the sliding block 24 can carry the conveying pipe 22 toward the adjacent Figure 2 When the delivery pipe 22 is pushed and moved to the maximum distance, that is, the end of the right-angle transfer pipe 26 abuts against the accommodating annular groove 32, and the upper end of the delivery pipe 22 also moves to the top of the receiving tube 21, due to the effect of the arc portion 29, the above state can be maintained for a short period of time. During this period of time, because the right-angle transfer pipe 26 and the docking plate 31 abut against each other and seal, the air entering through the air intake pipe 13 and the air hole 33 can only be left inside the right-angle transfer pipe 26. At this time, the suction pump 14 continues to suck the gas inside the sealing frame 12, so that the air pressure inside the sealing frame 12 is reduced, and the air in the right-angle transfer pipe 26 is The gas pressure inside 26 remains unchanged. At this time, under the action of the pressure difference, the cooling liquid inside the right-angle transfer tube 26 can be injected into the receiving tube 21 through the delivery pipe 22, and the cooling liquid inside the receiving tube 21 can submerge the lower port of the exhaust pipe 15. At this time, the suction pump 14 will directly transport a small amount of cooling liquid to the extension tube 7 and the expansion tube 8. Since the temperature inside the expansion tube 8 is too high, the cooling liquid can be instantly vaporized. The vaporization will cause the air pressure in the hollow cavity to increase, thereby increasing the discharge flow rate of the hot air flow at the exposed end of the extension tube 11, which can further increase the effect of removing carbonized impurities attached to the surface of the edge pulling wheel 2.

[0046] In this solution, the coolant is water.

[0047] Example 3: Please refer to Figure 6 and Figure 7 This embodiment is a further explanation of the first and second embodiments. The end of the extension tube 11 close to the edge drawing wheel 2 is closed, and a strip-shaped exhaust slit 34 is provided on the outer surface of the extension tube 11. The direction of the exhaust slit 34 is tangent to the arc surface of the edge drawing wheel 2. When the high-speed hot air flow is discharged through the exhaust slit 34, the carbonized impurities attached to the surface of the edge drawing wheel 2 can be blown off.

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