Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of glass production equipment, and more specifically relates to an overflow port retaining device for rolled glass. Background Art
[0002] In the production of rolled glass, traditional refractory edge bricks are generally used. However, their easy breakage and large edge of the original plate cannot be improved. At the same time, the traditional edge device cannot flexibly expand or shrink the plate. If the edge bricks are used for too long, cold glass liquid will often form on the edges, which is prone to crystallization and roller lines will appear on the edges, seriously affecting the output and quality of the glass. In order to enhance the competitiveness of enterprises, a new type of edge device must be developed to solve these drawbacks so that enterprises can survive in the increasingly fierce competitive environment.
[0003] The defects of the existing technology are as follows: 1. The existing retaining bricks are generally made of materials such as sillimanite, mullite, and zircon. They are easily cracked by the hot and cold erosion of glass liquid during use, and can only be discarded after each machine change, and cannot be reused, resulting in high production costs; 2. The existing refractory retaining bricks cannot expand or shrink the board according to the order after the original board width is fixed. After the large board is changed to a small board, the edge cleaning becomes larger, and cold glass liquid is formed at the edge for a long time, which is easy to crystallize and seriously affects the yield rate; 3. The existing refractory retaining bricks, after the tip of the mouth is made into an arc surface, the tip cannot be made as thin as the metal retaining (the refractory material is very easy to break after reaching a certain thickness), and the edge cleaning loss is large.

The lip brick is fixedly mounted on the upper end of the fixing frame, and the anti-overflow unit is fixedly mounted on the upper end of the fixing frame by bolts at both ends of the lip brick, and the corresponding sides of the two anti-overflow units are both in contact with the lip brick. The utility model blocks the overflow outlet of the glass plate, and well realizes the extension or contraction of the overflow outlet glass liquid, meeting the production requirements of glass plates of various specifications; it can also be used online for a long time with almost no damage, greatly extending the production changeover cycle and reducing the production cost; the device is an independent system, which is easy to install and disassemble, strong and durable, can better replace the side bricks, and is more convenient to operate in production. However, the technology does not involve the technical problems and technical solutions of the present application. Utility Model Content

DETAILED DESCRIPTION
[0023] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connection relationships of the components involved, the functions and working principles of the components, etc., by referring to the accompanying drawings:
[0024] As attached Figure 1 -Attached Figure 3 As shown, the utility model is a rolled glass overflow rib device, comprising a rib device body 1, the rib device body 1 is a hollow structure, a fixing hole 1-1 and a burning hole 1-2 are arranged on one side of the rib device body 1, a circular arc surface 1-4 is arranged on the side of the rib device body 1 close to the pressure roller 5, a pointed mouth portion 1-3 is arranged at the lower end of the circular arc surface 1-4, and the pointed mouth portion 1-3 includes an upper arc surface 1-5 and a lower arc surface 1-6. The above structure proposes an improved technical solution to address the deficiencies in the prior art. When setting up the structure, a high temperature resistant metal material is used to make the side guard device body 1. The side guard device body 1 is a hollow structure. A fixing hole 1-1 and a burning hole 1-2 are set on one side of the side guard device body 1. When in use, the side guard device body 1 is placed on the lip brick. The fixing hole 1-1 is used to connect the side guard device body 1 with the fixing component to achieve the position fixation of the side guard device body 1 on the lip brick. A circular arc surface 1-4 is set on the side of the side guard device body 1 close to the pressure roller 5. The circular arc surface 1-4 is close to one pressure roller 5, and a sharp mouth 1-3 is set at the lower end of the circular arc surface 1-4. The sharp mouth 1-3 includes an upper arc surface 1-5 and a lower arc surface 1-6. The upper arc surface 1-5 is close to the upper pressure roller 5, and the lower arc surface 1-6 is close to the lower pressure roller 5. In this way, the structural arrangement can be realized conveniently and reliably. When the side guard device is in use, the heating gun barrel extends into the combustion hole 1-2 and enters the hollow cavity inside the side guard device body 1. The natural gas and the combustion-supporting air mixed in proportion are connected to the hollow cavity inside the side guard device body 1 through pipelines to realize the supply of natural gas and the air required for combustion. The natural gas burns in the hollow cavity, and the edge temperature is maintained by the heat generated by the combustion, that is, the temperature of the part close to the pressure roller is maintained by heating the arc surface 1-4. The heat-resistant steel used in the side guard device body 1 has good thermal conductivity, which can ensure that the side guard device close to the glass liquid side maintains the temperature required for production, and there will be no cold shortage of glass liquid at the corner of the edge. The sharp mouth 1-3 of the side guard device is made into upper and lower double arc surfaces, namely the upper arc surface 1-5 and the lower arc surface 1-6, which can ensure that the sharp mouth 1-3 contacts the upper roller 3 and the lower roller 4 at the minimum distance, greatly reducing the edge cleaning of the glass original plate. The arc surface 1-4 of the side guard device body 1 gradually shrinks from the inside (close to the glass liquid side) to the outside to prevent it from hitting the upper roller 3. In summary, the rolled glass overflow port side guard device described in the utility model has a simple structure, can meet the side guard needs of glass production, can be disassembled and cleaned and reused after the machine is changed, thereby reducing edge cleaning losses, improving thermal insulation effects, reducing defects such as crystallization of edge glass and pressure roller lines, improving glass production quality, and reducing enterprise production costs.
[0025] A positioning step 6 is provided at the junction of the side guard device body 1 and the pointed mouth portion 1-3. When the side guard device body 1 is arranged on the lip brick 2, the positioning step 6 is provided as a structure that can be clamped on the lip brick 2. In the above structure, the side guard device body 1 is arranged at the upper position of the lip brick 2 when in use, and the arc surface 1-4 of the side guard device body 1 is close to the pressure roller. A side guard device is provided on both sides of the lip brick 2, so that the side guard is performed from both sides of the pressure roller 5, which can reliably cooperate with glass production. When the side guard device is in use, the two side guard devices on both sides are arranged symmetrically, and the fixing hole 1-1 and the combustion hole 1-2 on each side guard device are located outside the device body.
[0026] The heating gun is arranged at the position of the combustion hole 1-2 and extends to the internal position of the side guard device body 1, and the side guard device body 1 is also connected to the combustion natural gas pipeline. In the above structure, when the side guard device is used, the heating gun barrel extends into the combustion hole 1-2 and enters the hollow cavity inside the side guard device body 1, and the natural gas and the combustion-supporting air mixed in proportion are respectively connected to the hollow cavity inside the side guard device body 1 through the pipeline, so as to realize the supply of natural gas and the air required for combustion. The natural gas burns in the hollow cavity, and the edge temperature is maintained by the heat generated by the combustion.
[0027] The side guard device body 1 is configured as a structure made of heat-resistant steel. With the above structure, the side guard device has high strength and can be reused, which increases the service life and reduces the production cost. At the same time, the side guard device body 1 is resistant to high temperatures and has good thermal conductivity, which effectively improves the heat transfer effect.
[0028] The rolled glass overflow port retaining device also includes a device body side plate 8, and a long rod 9 is welded on the outer side of the device body side plate. The long rod is used by the operator to move the high-temperature retaining device over a long distance. It is easy to use and protects the operator from close contact with the device body to avoid burns.
[0029] The pressure rollers 5 include an upper roller 3 and a lower roller 4. The main body 1 of the edge guard device is arranged on the lip brick 2. When the main body 1 of the edge guard device is arranged on the lip brick 2, the pointed mouth 1-3 is configured to be able to extend to the roller gap 7 position of the upper roller 3 and the lower roller 4. In the above structure, the pointed mouth 1-3 of the edge guard device is made into upper and lower double arc surfaces, namely, an upper arc surface 1-5 and a lower arc surface 1-6, which can ensure that the pointed mouth 1-3 is in contact with the upper roller 3 and the lower roller 4 at a minimum distance, and can reliably guard the edges from both sides. To reduce the size of the original glass plate and clean the edges, the arc surface 1-4 of the main body 1 of the edge guard device gradually shrinks from the inside (close to the glass liquid side) to the outside to prevent it from hitting the upper roller 3.
[0030] The fixing hole 1-1 is a steel pipe welded to the side of the side guard body 1. In the above structure, the steel pipe is used to insert the rod, which is a fixing part of the production line, and can reliably fix the position of the side guard body 1 on the lip brick, effectively avoiding movement during glass production.
[0031] The utility model discloses a rolled glass overflow port retaining device. When the structure is set, the retaining device body 1 is made of a high temperature resistant metal material. The retaining device body 1 is a hollow structure. A fixing hole 1-1 and a burning hole 1-2 are set on one side of the retaining device body 1. When in use, the retaining device body 1 is placed on the lip brick. The fixing hole 1-1 is used to connect the retaining device body 1 with the fixing component to achieve the position fixation of the retaining device body 1 on the lip brick.

The arc surface 1-4 is close to one pressure roller 5, and a sharp mouth 1-3 is provided at the lower end of the arc surface 1-4. The sharp mouth 1-3 includes an upper arc surface 1-5 and a lower arc surface 1-6. The upper arc surface 1-5 is close to the upper pressure roller 5, and the lower arc surface 1-6 is close to the lower pressure roller 5. In this way, the structural arrangement can be realized conveniently and reliably. When the side guard device is in use, the heating gun barrel extends into the combustion hole 1-2 and enters the hollow cavity inside the side guard device body 1. The natural gas and the combustion-supporting air mixed in proportion are connected to the hollow cavity inside the side guard device body 1 through pipelines to realize the supply of natural gas and the air required for combustion. The natural gas burns in the hollow cavity, and the edge temperature is maintained by the heat generated by the combustion, that is, the temperature of the part close to the pressure roller is maintained by heating the arc surface 1-4. The heat-resistant steel used in the side guard device body 1 has good thermal conductivity, which can ensure that the side guard device close to the glass liquid side maintains the temperature required for production, and there will be no cold shortage of glass liquid at the corner of the edge. The sharp mouth 1-3 of the side guard device is made into upper and lower double arc surfaces, namely the upper arc surface 1-5 and the lower arc surface 1-6, which can ensure that the sharp mouth 1-3 contacts the upper roller 3 and the lower roller 4 at the minimum distance, greatly reducing the edge cleaning of the glass original plate. The arc surface 1-4 of the side guard device body 1 gradually shrinks from the inside (close to the glass liquid side) to the outside to prevent it from hitting the upper roller 3.
