The transition rollers are driven by chain drive, and the transition rollers are equipped with water cooling devices, and the ceramic layer coated on the surface of the transition rollers can be cooled by adjusting the amount of water.
[0003] In existing large-tonnage furnaces, due to the excessive length of the channel outlet, the glass temperature is relatively low after the glass liquid enters the calender from the lip bricks. Therefore, several external torches need to be additionally installed on both sides to heat and ensure the smooth extraction of the glass. The bearings and chains are easily damaged under the influence of external fire. The methods for repairing the transition roller table include online replacement of bearings and chains or pushing out the transition rollers for maintenance by lowering the gate plate. However, the online replacement method has high temperature and great difficulty, while the maintenance by pushing out the transition rollers with the gate plate takes a long time and there is no product output for a long time. Therefore, we need to propose a replacement device for a large-tonnage photovoltaic calendered glass transition roller table. Content of the Utility Model

Detailed Embodiments
[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with 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.
[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: a replacement device for a large-tonnage photovoltaic rolled glass transition roller table, including two groups of chain hoists 2 and two groups of temporary transition roller table device fixing I-beams 4 arranged symmetrically. The lower ends of the two groups of chain hoists 2 are respectively installed at one end of the two groups of temporary transition roller table device fixing I-beams 4 close to the calender. A plurality of glass guiding pipe installation angle steel assemblies 7 are installed on the lower surfaces of the temporary transition roller table device fixing I-beams 4. The plurality of glass guiding pipe installation angle steel assemblies 7 are arranged at equal intervals. A glass guiding galvanized pipe 5 is rotatably connected to the two corresponding glass guiding pipe installation angle steel assemblies 7. A glass guiding pipe limiting screw 6 for restricting the glass guiding galvanized pipe 5 is threadedly connected to the two corresponding glass guiding pipe installation angle steel assemblies 7. Assembled part anti-slip devices 8 are welded on both sides of the two groups of temporary transition roller table device fixing I-beams 4.
[0020] It further includes two groups of upper and lower rollers 1. A rolled glass body 10 is arranged between the two groups of upper and lower rollers 1. One end of the rolled glass body 10 is arranged above the plurality of glass guiding galvanized pipes 5. The number of the glass guiding pipe installation angle steel assemblies 7 is set according to the actual distance between the calender and the annealing kiln. Similarly, the number of the glass guiding galvanized pipes 5 is the same as that of the symmetrically arranged glass guiding pipe installation angle steel assemblies 7, and the glass guiding galvanized pipes 5 can rotate on the glass guiding pipe installation angle steel assemblies 7.
[0021] It further includes a plurality of calender auxiliary rollers 3 arranged at equal intervals. The rolled glass body 10 rolls on the outer sides of the plurality of calender auxiliary rollers 3, and the stability of the rolled glass body when it exits the calender is improved by the plurality of calender auxiliary rollers 3.
[0022] It further includes a plurality of annealing kiln roller tables 9 arranged at equal intervals. The stability of the rolled glass body 10 when it enters the annealing kiln after exiting the calender is ensured by the annealing kiln roller tables 9.
[0023] The planes where the tops of multiple sets of calender auxiliary rollers 3 are located and the planes where the tops of multiple sets of annealing kiln roller tables 9 are located are both set in the same plane. Multiple sets of glass guiding galvanized pipes 5 are arranged between multiple sets of calender auxiliary rollers 3 and multiple sets of annealing kiln roller tables 9. By setting the calender auxiliary rollers 3, the glass guiding galvanized rollers and the annealing kiln roller tables 9 in the same plane, the deformation of the calendered glass body 10 during transportation is avoided, and the production quality of the calendered glass body 10 is improved.
[0024] At one end of the fixed I-beam 4 of the two sets of temporary transition roller table devices away from the upper and lower rollers 1, they are both arranged on the steel structure outside the annealing kiln. The distance between the two corresponding glass guiding pipe installation angle steel assemblies 7 is smaller than the distance between the two fixed I-beams 4 of the temporary transition roller table devices. The angle of the fixed I-beam 4 of the temporary transition roller table device can be conveniently adjusted by the chain block 2. While facilitating the adjustment of the leading-out angle of the calendered glass body 10, it does not affect the production of the calendered glass body 10 during disassembly, thus improving the production efficiency.
[0025] During use, the calendered glass body 10 is calendered by the upper and lower rollers 1 of the calender. The angle of the fixed I-beam 4 of the temporary transition roller table device is adjusted by the chain block 2, thereby facilitating the adjustment of the leading-out angle of the calendered glass body 10. At the same time, the glass guiding pipe limiting screw 6 should be long enough to ensure that the glass guiding galvanized pipe 5 can smoothly lead out the glass. The processed calendered glass body 10 passes through multiple sets of calender auxiliary rollers 3, multiple sets of glass guiding galvanized pipes 5 and multiple sets of annealing kiln roller tables 9 in sequence and enters the annealing kiln. When it is necessary to replace the glass guiding galvanized pipe 5 under the fixed I-beam 4 of the temporary transition roller table device, the angle of the fixed I-beam 4 of the temporary transition roller table device is adjusted downward by the chain block 2, so that the glass guiding galvanized pipe 5 is separated from the calendered glass body 10. Then, by loosening and tightening the glass guiding pipe limiting screw 6, the rapid disassembly and assembly of the glass guiding galvanized pipe 5 are realized, improving the replacement efficiency and avoiding the problem of no product output for a long time caused by closing the gate and cutting off the glass head for the maintenance of the transition roller table.
[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
