Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of glass forming, and particularly relates to a combined floating float glass sealing box tin wiping device. Background Art
[0002] The tin bath and annealing lehr are two important process sections in the production of float glass. The transition roller table and the sealing box are located between the tin bath and the annealing lehr as a whole, connecting the two process sections. The function of the transition roller table is to pull the glass in the tin bath out and send it to the annealing lehr for annealing, while the function of the sealing box is to ensure the sealing of the tail of the tin bath and to remove the tin slag brought out from the milling groove on the lower surface of the glass.
[0003] Specifically, after the glass ribbon comes out of the tin bath, the lower part will bring out the tin slag in the tin bath. When passing through the transition roller, the tin slag adheres to the surface of the roller. If the tin slag on the surface of the roller is not cleaned in time, it will scratch the glass surface, affecting the quality of the glass and causing the glass to be unqualified.
[0004] Therefore, in the actual production process, it is necessary to continuously clean the tin slag on the surface of the roller. However, since the roller is located in a sealed box, it is difficult to clean it under the partition of the sealed box.
[0005] In order to solve this technical problem, the workshop currently cleans the rollers by installing graphite blocks in a sealed box. However, as the friction between the graphite blocks and the rollers continues, the wear gradually increases, resulting in excessive wear and a gradual increase in the gap between the graphite blocks and the rollers. When the gap increases, it is necessary to adjust the graphite blocks so that they are close to the roller surface in order to remove the residual tin slag on the roller body.
[0006] Since the graphite block is located in a sealed box, it is difficult to adjust the graphite block. Utility Model Content
[0007] Based on the above background, the purpose of the utility model is to provide a combined floating float glass sealing box tin wiping device.
[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:
[0009] A combined floating float glass sealing box tin wiping device comprises a sealing box and a glass conveying roller installed in the sealing box, and the combined floating float glass sealing box tin wiping device also comprises a tin wiping mechanism for cleaning residues on the surface of the glass conveying roller;
[0010] The tin-wiping mechanism comprises a balance beam installed in a sealed box, and the balance beam is arranged below the glass conveying roller;
[0011] The balance beam is slidably assembled with a plurality of tin-wiping units, the tin-wiping units include graphite blocks, and a plurality of floating lowering rods slidably connected to the balance beam are fixedly installed at the bottom of the graphite blocks;
[0012] The tin-wiping mechanism also includes a self-adjusting structure for lifting the floating rod, and the self-adjusting structure includes a steel wire rope, and both ends of the steel wire rope are respectively fixedly assembled and connected with a counterweight block;
[0013] The steel wire rope is supported at the bottom of the floating lowering rod, and the contact pressure between the graphite block and the glass conveying roller is adjusted by the upward or downward movement of the steel wire rope.
[0014] Preferably, the tin-wiping unit further comprises a lifting base fixedly connected to the bottom position of the floating lowering rod.
[0015] Preferably, a pulley seat is fixedly connected to the top of the lifting base, and a supporting pulley is rotatably connected to the pulley seat;
[0016] The steel wire rope is supported at the bottom of the supporting pulley.
[0017] Preferably, a wheel groove cooperating with the steel wire rope is provided on the contour of the supporting pulley, and the steel wire rope is stuck in the wheel groove.
[0018] Preferably, a plurality of guide pulleys for guiding steel wire ropes are fixedly connected to the balance beam;
[0019] The steel wire rope is inserted in sequence between the guide pulley and the support pulley.
[0020] Preferably, both ends of the steel wire rope are respectively fixedly connected with quick-reaction springs, and the quick-reaction springs are hung on the counterweight block.
[0021] Preferably, hooks are integrally formed on the top and bottom of the quick-reaction spring, and the hooks are used to hang the wire rope and the counterweight respectively.
[0022] Preferably, the graphite block removes the tin slag remaining on the glass conveying roller by friction with the glass conveying roller.
[0023] Preferably, two ends of the steel wire rope respectively pass through two sides of the sealing box and are fixedly assembled and connected with a counterweight block located outside the sealing box.
[0024] The utility model has the following beneficial effects:
[0025] 1. During the working process, the graphite block is the basis for tin wiping and is divided into several independent tin wiping units. By setting counterweights on both sides, the counterweights tighten the steel wire rope and apply appropriate compression force to the graphite block through the steel wire rope. The pressure between the graphite block on each tin wiping unit and the glass conveyor roller is the same.
[0026] 2. When a section of graphite block is separated from the surface of the glass conveyor roller due to wear or the pressure is reduced, the force on the corresponding section of the wire rope will be reduced, the wire rope will loosen, and slide to other sections, causing the wire ropes in all sections to loosen slightly, the tension will be reduced, the counterweight block will drop, the wire rope will be tightened, and the compression force of the graphite block will be maintained.
[0027] 3. When the pressing force of a section of graphite block increases due to the vibration of the glass conveyor roller or the obstruction of tin slag, the tension of the wire rope in the corresponding section increases, and pulls the wire rope in other areas to slide toward this section. The pressure of all graphite blocks increases evenly, causing the counterweight block to rise, keeping the pressing force of the graphite block stable and protecting the surface of the glass conveyor roller.
[0028] 4. The self-adjusting method disclosed in the utility model can flexibly adjust the pressing force between the graphite block and the glass conveying roller, ensuring that the tin slag remaining on the glass conveying roller can be removed in a relatively stable and efficient manner.

[0038] Example 1
[0039] like Figure 1-4 As shown, a combined floating float glass sealing box tin wiping device comprises a sealing box 1 and a glass conveying roller 3 installed in the sealing box 1. Specifically, the sealing box 1 is installed between the tin bath and the annealing furnace to connect the two process sections, and the glass conveying roller 3 installed in the sealing box 1 is used to draw the glass in the tin bath out and send it into the annealing furnace for annealing, while the sealing box 1 is used to ensure the sealing of the tail of the tin bath.
[0040] Similar to the existing method, a driving structure 31 for driving the glass conveying roller 3 to rotate is installed on the outer side of the sealing box 1, and specifically, the driving structure 31 is similar to the existing method and is driven by a gear box and a motor component.
[0041] In order to remove the residual tin slag on the glass conveying roller 3 , the following improvement is made: the tin wiping device of the combined floating float glass sealing box 1 also includes a tin wiping mechanism 2 for removing the residual on the surface of the glass conveying roller 3 .
[0042] Specifically, the tin-wiping mechanism 2 includes a balance beam 21 installed in the sealing box 1 , and the balance beam 21 is arranged below the glass conveying roller 3 .
[0043] Meanwhile, a plurality of tin-wiping units are slidably assembled and connected to the balance beam 21 . The tin-wiping units include graphite blocks 23 . A plurality of floating lowering rods 24 slidably connected to the balance beam 21 are fixedly mounted at the bottom of the graphite blocks 23 .
[0044] The tin wiping mechanism 2 also includes a self-adjusting structure for raising and lowering the floating rod 24, and the self-adjusting structure includes a steel wire rope 22, and both ends of the steel wire rope 22 are respectively fixedly assembled and connected with a counterweight block 26 (specifically, the two ends of the steel wire rope 22 respectively pass through the two sides of the sealing box 1 and are fixedly assembled and connected to the counterweight block 26 located outside the sealing box 1).
[0045] Specifically, the tin-wiping unit further includes a lifting base 2411 fixedly connected to the bottom of the floating rod 24. A pulley seat is fixedly connected to the top of the lifting base 2411, and a support pulley 241 is rotatably connected to the pulley seat; the wire rope 22 is supported at the bottom of the support pulley 241.
[0046] A wheel groove matching with the steel wire rope 22 is provided on the profile of the supporting pulley 241, and the steel wire rope 22 is stuck in the wheel groove.
[0047] In order to guide the wire rope 22, a plurality of guide pulleys 25 for guiding the wire rope 22 are fixedly connected to the balance beam 21 (similarly, a wheel groove for limiting the position of the wire rope 22 is provided on the contour of the guide pulley 25); the wire rope 22 is inserted between the guide pulley 25 and the support pulley 241 in sequence.
[0048] Specifically, the guide pulley 25 is arranged as follows:
[0049] Two guide pulleys 25 spaced apart vertically are arranged on the left and right sides of the balance beam 21 to guide the wire rope 22 to droop, so as to facilitate the hanging of the counterweight 26. At the same time, a number of guide pulleys 25 distributed on both sides of the support pulley 241 are arranged on the balance beam 21. The wire rope 22 is guided from the guide pulley 25 on one side to the bottom limit of the support pulley 241 and is lifted up again to be inserted through the guide pulley 25 on the other side. In this way, the wire rope 22 inserts the guide pulley 25 into the support pulley 241 in sequence and is supported at the bottom of the support pulley 241.
[0050] During the working process, the graphite block 23 is used as the tin-wiping basis and is divided into several independent tin-wiping units. By arranging counterweight blocks 26 on both sides, the counterweight blocks 26 tighten the steel wire rope 22, and apply appropriate clamping force to the graphite block 23 through the steel wire rope 22. The pressure between the graphite block 23 and the glass conveying roller 3 on each tin-wiping unit is the same.
[0051] When a section of graphite block 23 is separated from the surface of the glass conveying roller 3 or the pressure is reduced due to wear, the self-adjusting structure will adjust. Specifically, the force on the corresponding section of the wire rope 22 will be reduced, the wire rope 22 will loosen, and slide to other sections, causing the wire rope 22 in all sections to be slightly loose, the tension will be reduced, the counterweight block 26 will drop, the wire rope 22 will be tightened, and the pressing force of the graphite block 23 will be maintained.
[0052] When the pressing force of a section of graphite block 23 increases due to the vibration of the glass conveying roller 3 or the obstruction of tin slag, the tension of the steel wire rope 22 in the corresponding section increases, and pulls the steel wire rope 22 in other areas to slide toward this section. The pressure of all graphite blocks 23 increases evenly, and causes the counterweight block 26 to rise, keeping the pressing force of the graphite block 23 stable, thereby protecting the surface of the glass conveying roller 3.
[0053] Example 2
[0054] like Figure 1-4 As shown, in this embodiment, based on the structure of embodiment 1, both ends of the steel wire rope 22 are respectively fixedly connected with quick-reaction springs 261 , and the quick-reaction springs 261 are hung on the counterweight 26 .
[0055] Specifically, hooks are integrally formed at the top and bottom of the quick-reaction spring 261 , and the hooks are used to pull the steel wire rope 22 and the counterweight 26 , respectively.
[0056] Connected with the counterweight 26 by a quick-reaction spring, when the roller vibrates too much or is blocked by tin slag, causing the graphite block 23 to drop or rise quickly, this device can avoid the large inertia of the counterweight 26 and improve the response speed of the lifting device.
[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
