Since the ordinary float glass sheet is drawn out by the edge rollers in the glass kiln, the edges of the ordinary float glass sheet are given a plurality of impressions by gears in the edge rollers, and therefore, the edges of the ordinary float glass sheet need to be cut off later. In this embodiment, however, the edges of the electronic grade float glass sheet 70 are also provided with indentations, which also need to be cut later. The two sides of the electronic grade float glass sheet 70 are supported by two support rings 50, respectively. In the cooling idler, the opening of the blind hole 13 is sealed by a sealed bearing to form an air chamber, and the cold compressed air in the air inlet pipe 30 is discharged from the air hole 31 into the air chamber. In the exhaust hole 21, since the diameter of the small end of the tapered hole 211 is smaller than that of the metal ball 22, the metal ball 22 can block the tapered hole 211; the presence of the stop 23 prevents the metal ball 22 from falling into the air chamber. Because the gravity of the metal ball 22 is large, the exhaust hole 21 at the lower half part of the roller body 10 is blocked by the metal ball 22 under the dual actions of the gravity of the metal ball 22 and the thrust of the cold compressed air in the air chamber, so that the exhaust hole 21 at the lower half part of the roller body 10 can not spray the cold compressed air. In the upper half of the roll body 10, the pushing force of the cold compressed air to the metal balls 22 is far smaller than the gravity of the metal balls 22, so that the metal balls 22 cannot block the tapered holes 211, the diameter of the through holes 212 is larger than that of the metal balls 22, enough gaps exist between the inner walls of the through holes 212 and the metal balls 22 for the cold compressed air to pass through, the cold compressed air in the air chamber can pass through the through holes 212 and the tapered holes 211 of the part, that is, the exhaust holes 21 in the upper half of the roll body 10 continuously spray out the cold compressed air, the cold compressed air can act on the lower surface of the electronic grade float glass plate 70 so as to effectively support the electronic grade float glass plate 70, meanwhile, the cold compressed air can cool the electronic grade float glass plate 70, the lower surface of the electronic grade float glass plate 70 is isolated from gas, meanwhile, the edge of the electronic grade float glass plate 70 is contacted with the supporting ring 50, the electronic grade float glass plate 70 can move forward through the friction force between the two parts, and finally the edge of the electronic grade float glass plate 70 is cut, so that the electronic grade float glass plate 70 can not be scratched, but the electronic grade float glass plate 70 can also have large quality and can be prevented from damaging the electronic grade float glass plate 70.
The half shaft 11 and the shaft tube 12 are both rotationally connected with the carrier roller seat, the roller body 10 is fixed in the rotating process, the air inlet pipe 30 is fixed, the sealed bearing can ensure the rotating connection between the air inlet pipe 30 and the roller body 10, and meanwhile, a gap is formed between the tail end of the air inlet pipe 30 and the bottom of the blind hole 13. Even if the roll body 10 is continuously rotated, the exhaust holes 21 in the lower half of the roll body 10 are blocked by the metal balls 22 therein, and cold compressed air can be continuously sprayed out of the exhaust holes 21 in the upper half of the roll body 10, and the cold compressed air can assist in supporting the electronic grade float glass plate 70, so that the electronic grade float glass plate 70 can stably advance, and the electronic grade float glass plate 70 can be cooled. Because the rotating speed of the roll body 10 is usually 8-30 r/min, the centrifugal force generated by the rotation of the roll body 10 is very small, the gravity of the metal ball 22 is large, the influence of the centrifugal force on the metal ball 22 is small, and the lead ball with large density can be selected, so that the exhaust hole 21 in the upper half part of the roll body 10 can continuously spray cold compressed air. If the metal balls 22 are not present, the air discharge holes 21 around the roll body 10 can discharge cold compressed air, and the lower half of the roll body 10 discharges cold compressed air which is not used for supporting the electronic grade float glass plate 70, only the cold compressed air is wasted. Therefore, the amount of the cold compressed air is small, and resources are saved. Wherein, the outer ring surface of the supporting ring 50 is provided with a convex line, and the existence of the convex line can greatly increase the friction force between the edge of the electronic grade float glass plate 70 and the supporting ring 50, thereby further ensuring the stable advancing of the electronic grade float glass plate 70. The coils 51 at two sides of the supporting ring 50 can tightly support the supporting ring 50, so that the supporting ring 50 and the roller body 10 are prevented from rotating again. The outer diameter of the coils 51 is smaller than the outer diameter of the support ring 50 so that the coils 51 do not act on the edges of the electronic grade float glass sheet 70.
Since the air compressor 1 needs to produce compressed air at intervals, the compressed air produced by the air compressor 1 is temporarily stored and cooled in the first air tank 4 and the second air tank 7. When the cooling carrier roller works, the third electromagnetic valve 8 is firstly opened, the second electromagnetic valve 5 is in a closed state, and the air compressor 1 can continuously charge air into the first air tank 4; after the air pressure in the second air tank 7 drops to a certain extent, the second electromagnetic valve 5 is opened so that the cold compressed air in the first air tank 4 can be input into the second air tank 7; in this way, the air compressor 1, the first electromagnetic valve 2, the first ice bath 3, the first air tank 4, the second electromagnetic valve 5, the second ice bath 6 and the second air tank 7 cooperate, and uninterrupted cold compressed air can be provided for the cooling carrier roller. The top of the first air tank 4 is provided with a first air pressure gauge 41, and the first air pressure gauge 41 is used for measuring air pressure inside the first air tank 4. The top of the second gas tank 7 is provided with a second barometer 71, and the second barometer 71 is used for measuring the gas pressure inside the second gas tank 7.
Example 2
The width of the electronic grade float glass sheet 70 varies from customer to customer, in order to meet the production requirements of electronic grade float glass sheets 70 of various widths, while avoiding the waste of cold compressed air. The structure of the cooling carrier roller is further improved on the basis of the embodiment 1, as shown in fig. 5 and 6, two parts of the head and the tail of the roller body 10 are respectively sleeved with an internal thread pipe 60, and the internal thread pipe 60 is in threaded connection with the roller body 10; the head end of the internally threaded tube 60 is disposed outside the roll body 10, an externally threaded ring 63 adapted to the internally threaded tube 60 is disposed inside the internally threaded tube 60, and the externally threaded ring 63 is in threaded connection with the internally threaded tube 60. The tail end of the internally threaded tube 60 is provided with a turned-over edge 601, a first rubber gasket 61 is arranged between the turned-over edge 601 and the spiral ring 51, and the first rubber gasket 61 is sleeved outside the roller body 10; the inside of the internally threaded tube 60 is also provided with a second rubber washer 62, the second rubber washer 62 being disposed between the externally threaded ring 63 and the end of the roll body 10.
The edge of the electronic grade float glass sheet 70 is supported by the support ring 50. When the width of the electronic float glass plate 70 needs to be reduced, the coils 51 at both sides of the supporting ring 50 need to be loosened, then the supporting rings 50 are rotated respectively until the distance between the two supporting rings 50 is reduced to a set value, and then the coils 51 are rotated until the coils 51 at both sides of the supporting rings 50 tightly support the supporting rings 50; subsequently, the externally threaded ring 63 is taken out from the inside of the internally threaded tube 60, the externally threaded ring 63 is a ring with threads on the outer ring, and the internally threaded tube 60 is rotated by the flange 601 until the flange 601 can press the first rubber gasket 61 against the outermost coil 51; finally, the externally threaded ring 63 is screwed with the internally threaded tube 60 until the externally threaded ring 63 can press the second rubber gasket 62 against the end of the roll body 10. Similarly, when the width of the electronic float glass plate 70 needs to be increased, the coils 51 at both sides of the support ring 50 need to be loosened, then the support ring 50 is rotated until the distance between the two support rings 50 is increased to a set value, and then the coils 51 are rotated until the coils 51 at both sides of the support ring 50 tightly support the support ring 50; subsequently, the externally threaded ring 63 is taken out from the inside of the internally threaded tube 60, and the internally threaded tube 60 is turned until the flange 601 can abut the first rubber gasket 61 against the outermost coil 51; finally, the externally threaded ring 63 is screwed with the internally threaded tube 60 until the externally threaded ring 63 can press the second rubber gasket 62 against the end of the roll body 10. Because the distance between the two supporting rings 50 can be adjusted at any time according to the width of the electronic grade float glass plate 70, the supporting rings 50 always support the edge of the electronic grade float glass plate 70, and the internal thread pipe 60 can block the exhaust holes 21 of the electronic grade float glass plate 70, which cannot be applied to the front end and the rear end of the roll body 10, so that a large amount of cold compressed air can be saved. The first rubber gasket 61 and the second rubber gasket 62 can block the gap between the internally threaded pipe 60 and the roll body 10, and further ensure the sealing property.
The outer side of the external thread ring 63 is symmetrically provided with a plurality of push rods 64, the central axis of each push rod 64 is perpendicular to the plane of the outer side wall of the external thread ring 63, and the tail end of each push rod 64 is fixedly connected with the outer side wall of the external thread ring 63. The external thread ring 63 can be rotated by holding the push rod 64, which saves time and effort.
In order to facilitate the first rubber gasket 61 to be sleeved outside the roller body 10, the inner ring of the first rubber gasket 61 is in clearance fit with the roller body 10; to facilitate the insertion of the second rubber gasket 62 into the interior of the internally threaded tube 60, the outer race of the second rubber gasket 62 is in clearance fit with the interior cavity of the internally threaded tube 60.
In the above embodiment, the two supporting rings 50 in the cooling roller support the two edges of the electronic float glass plate 70 respectively, and the exhaust holes 21 in the upper half of the roller body 10 can continuously spray the cold compressed air to effectively support the middle part of the electronic float glass plate 70, so that the middle part of the electronic float glass plate 70 can not produce quality problems such as scratch, scratch and the like, and can also cool the electronic float glass plate 70; the electronic grade float glass plate 70 can advance by the friction force between the edge of the electronic grade float glass plate 70 and the supporting ring 50, and a finished product with a large area and no scratch on the surface can be obtained as the edge of the electronic grade float glass plate 70 is cut off; the electronic grade float glass sheet 70 is not required to be cut into a plurality of small pieces, so that the yield is remarkably improved. During the use process of the cooling carrier roller, only the exhaust holes 21 in the upper half part of the roller body 10 can spray out cold compressed air, and the exhaust holes 21 in the lower half part of the roller body 10 are blocked, so that the cold compressed air can be fully utilized and the cold compressed air can be saved. The cooling carrier roller can also be applied to the production of a plurality of electronic-grade float glass plates 70 with different widths, the air compressor 1, the first electromagnetic valve 2, the first ice bath 3, the first air tank 4, the second electromagnetic valve 5, the second ice bath 6 and the second air tank 7 are matched in a cooperative manner, uninterrupted cold compressed air can be provided for the cooling carrier roller, and the implementation effect is good.
