Description

Technical Field

[0001] This utility model belongs to the field of float glass production and forming technology, and specifically relates to a float glass positioning and edge-blocking device. Background Technology

[0002] In current float glass production lines, the tin bath is a crucial piece of equipment used in float glass production and forming. The tin bath typically consists of an inlet, a main body, and an outlet. During float glass forming, molten glass from the glass furnace flows through channels and troughs, entering the main body of the tin bath from its inlet. There, under the influence of gravity and surface tension, the molten glass undergoes processes such as spreading, thinning, cooling, and solidification on the molten tin surface, forming a glass ribbon of uniform thickness. This glass ribbon is then output from the outlet of the tin bath to a transition roller table and finally enters the annealing furnace.

[0003] However, in actual thin glass production, when the glass strip width in the tin bath reaches a certain position during thinning, if the temperature of the molten glass flowing in from the inlet of the flow channel is too high, the instantaneous flow rate of the molten glass will be large. This can directly cause "edge adhesion" or even more serious "bath fullness" accidents during the thinning process. Therefore, to prevent the high-temperature molten glass from sticking to the tin bath side bricks, and utilizing the principle that graphite lubrication and high-temperature molten glass do not wet each other, it is often necessary to install graphite baffles between the tin bath side bricks and the molten glass to solve the "edge adhesion" or "bath fullness" problems.

[0004] To address the aforementioned issues, a pressure plate-type graphite retaining edge structure exists in current technology. While this solves the problems, it requires the pressure plate to be directly inserted into the graphite retaining edge for fixation. However, due to the inherent brittleness of graphite, its impact and deformation resistance are relatively weak. During interference fit assembly, pressing one part into the hole of another generates significant assembly stress. This stress can cause cracks in the graphite block, damaging the graphite retaining edge and reducing its service life.

[0005] In view of this, in order to solve the above problems, this utility model proposes a float glass positioning edge device that can improve the installation firmness and quick disassembly of graphite edge while extending the service life of graphite edge. The device has a simple structural design, is easy to assemble and disassemble, is easy to manufacture, and is robust and reliable. Utility Model Content

[0006] This utility model provides a float glass positioning and baffle device with a simple structure, convenient assembly and disassembly, easy production, and robust reliability. While improving the installation stability and quick disassembly of the graphite baffle, it also extends the service life of the graphite baffle. The specific solution is as follows: A float glass positioning edge-blocking device includes a milled edge, with insertion grooves at both ends of the milled edge and placement grooves on one side of each insertion groove. Insertion blocks are inserted into each insertion groove, and horizontal connecting blocks connected to the insertion blocks are provided in each placement groove. An inverted L-shaped connecting block is connected to one end of each horizontal connecting block away from the insertion block, and the horizontal part of the inverted L-shaped connecting block is arranged parallel to the insertion block. The two inverted L-shaped connecting blocks are detachably connected to two horizontal plates, and the two horizontal plates are fixedly connected to a connecting plate.

[0007] Furthermore, the two plug blocks and the horizontal connecting block are respectively fitted with the plug slot and the placement slot with clearance.

[0008] Furthermore, a fixing screw is fixedly connected to the inverted L-shaped connecting block on the side of the horizontal plate, and a through hole is provided on the horizontal plate for the fixing screw to pass through. The fixing screw is fixed to one side of the horizontal plate by a fixing nut.

[0009] Furthermore, two fixing screws are provided and spaced apart on one side of the vertical part of the inverted L-shaped connecting block, and two through holes are opened on the corresponding horizontal plate. The two fixing screws are respectively fixed to one side of the horizontal plate by fixing nuts.

[0010] Furthermore, a square positioning strip is fixed on the inverted L-shaped connecting block between the two fixed screws, and a positioning hole is provided on the horizontal plate for the positioning strip to be inserted.

[0011] Furthermore, an elastic sheet is provided between the inverted L-shaped connecting block and the horizontal plate, and the elastic sheet has holes through which the positioning strip and the fixing screw can pass.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] See Figures 1-5 A float glass positioning edge-blocking device includes a graphite edge-blocking 1. The graphite edge-blocking 1 has insertion grooves 2 at both ends, each groove 2 being square. Placement grooves 3 are respectively provided on one side of the graphite edge-blocking 1 of each insertion groove 2. Insertion blocks 4 are inserted into each insertion groove 2. Horizontal connecting blocks 5 connected to the insertion blocks 4 are respectively provided in each placement groove 3. The outer surface of the horizontal connecting blocks 5 is flush with the end face of the graphite edge-blocking 1. An inverted L-shaped connecting block 6 is connected to one end of each horizontal connecting block 5 away from the insertion block 4. The horizontal portion of the inverted L-shaped connecting block 6 is arranged parallel to the insertion block 4. The two inverted L-shaped connecting blocks 6 are detachably connected to two horizontal plates 7, and the two horizontal plates 7 are respectively fixedly connected to a connecting plate 8.

[0023] The preferred two plug-in blocks 4 and the horizontal connecting block 5 are respectively fitted with the plug-in groove 2 and the placement groove 3 with a clearance fit. The clearance fit can prevent the plug-in block 4 from being squeezed and damaged by the graphite retaining edge 1 when inserted into the plug-in groove 2.

[0024] The preferred inverted L-shaped connecting block 6 is fixedly connected to a fixing screw 9 on one side of the horizontal plate 7. The horizontal plate 7 has a through hole through which the fixing screw 9 can pass. The fixing screw 9 is fixed to one side of the horizontal plate 7 by a fixing nut 10. During installation, it is only necessary to use the fixing nut 10 to tighten the fixing screw 9 to one side of the horizontal plate 7 so that the plug-in blocks 4 on both sides can fix the graphite baffle 1. The operation is simple, convenient and quick.

[0025] The preferred fixing screws 9 are provided in two pairs and are arranged at intervals on one side of the vertical part of the inverted L-shaped connecting block 6. The corresponding horizontal plate 7 has two through holes. The two fixing screws 9 are fixed to one side of the horizontal plate 7 by fixing nuts 10. The provision of two fixing screws 9 can further strengthen the fixing of the inverted L-shaped connecting block 6, thereby improving the firmness of the graphite edge 1 installation.

[0026] A square positioning strip 11 is fixed on the inverted L-shaped connecting block 6 between the two fixed screws 9. The horizontal plate 7 has a positioning hole for the positioning strip 11 to be inserted. The square positioning strip 11 can further enhance the stability of the graphite retaining edge 1 and prevent it from shaking up and down.

[0027] An elastic sheet 12 is provided between the preferred inverted L-shaped connecting block 6 and the horizontal plate 7. The elastic sheet 12 has a hole through which the positioning strip 11 and the fixing screw 9 can pass. The setting of the elastic sheet 12 can further ensure that when the plug block 4 is pressed against the inner side of the plug groove 2, it has a certain tension, which greatly reduces the stress of the plug block 4 on the graphite retaining edge 1 when it is fixed.

[0028] The preferred two inverted L-shaped connecting blocks 6 are respectively provided with threaded holes on their horizontal parts, and each of the two threaded holes is provided with a tightening screw 13. Each of the two tightening screws 13 is fixed with a tightening block 14 at one end near the graphite retaining edge and a fixing nut 15 at the other end. The setting of the tightening screw 13 and the tightening block 14 can improve the lateral stability of the graphite retaining edge 1, making the installation more secure. In use, it is only necessary to use a wrench to tighten the fixing nut 15.

[0029] Preferably, reinforcing ribs 16 are fixedly connected between the two horizontal plates 7 and the connecting plate 8, wherein the setting of the reinforcing ribs 16 can improve the strength of the connecting plate 8.

[0030] The operation procedure of this utility model device is as follows: When replacing the graphite retaining edge 1, use a wrench to remove the four fixing nuts 10 respectively, tighten the fixing nuts 15 to move the clamping block 14 away from the graphite retaining edge 1, and then pull the two horizontal connecting blocks 5 to move the plugging block 4 away from the plugging groove 2 and remove the graphite retaining edge 1. During assembly, place the new graphite retaining edge 1 between the two plugging blocks 2, insert one end of the plugging block 2 into the plugging groove 2, and then tighten the inverted L-shaped connecting block 6 against the elastic sheet 12 by screwing the fixing nuts 10 onto the fixing screw 9. The plugging block 2 on the other side is installed in the same way. Then, use a wrench to tighten the fixing nuts 15 to make the clamping block 14 press against the side of the graphite retaining edge 1 to complete the assembly of the graphite retaining edge 1. This operation greatly improves the firmness of the graphite retaining edge 1 installation and also avoids damage to the graphite retaining edge 1 caused by installation, thereby improving the service life of the graphite retaining edge 1.
