Description

Technical Field

[0001] This utility model relates to the technical field of float glass tin bath process, and in particular to a tin bath transition roller graphite strip filling device. Background Technology

[0002] In float glass production, graphite strips are inserted into the slag box under the tin bath transition roller as one of the slag box sealing devices. There are three places in the slag box where graphite strips need to be inserted to contact and seal with the roller. Each place requires 12 graphite strips. As the tin bath is a highly sealed section, frequent opening of the slag box and prolonged insertion of graphite strips will cause a large amount of oxygen to enter the tin bath, which will aggravate the oxidation of the molten tin inside the tin bath and contaminate the quality of the glass products. In addition, during the insertion of graphite strips, the temperature in the slag box area can reach 600℃, which can easily cause burns. Therefore, a graphite strip filling device for the tin bath transition roller is needed. Utility Model Content

[0003] The purpose of this application is to provide a graphite strip filling device for a tin bath transition roller to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: a graphite strip filling device for a tin bath transition roller, including a support frame, a guide rail for placing graphite strips fixed at the upper end of the support frame, the guide rail being a U-shaped track, a pusher for driving the graphite strips to move on the guide rail installed inside the guide rail, and a drive structure for driving the pusher to move at the lower end of the guide rail.

[0005] The lower end of the support frame is equipped with a positioning lifting rod and casters. The positioning lifting rod is threadedly connected to the lower end of the support frame through a threaded structure. The threaded lower end of the positioning lifting rod passes through the lower end of the support frame and is fixed with a foot.

[0006] Preferably, the support frame includes end frames, crossbeams, and fixed feet. There are two end frames, which are fixed to both ends of the crossbeam respectively. The upper end of the crossbeam is fixed to the lower end of the guide rail. There are four fixed feet, which are symmetrically fixed in pairs to both sides of the lower end of the two end frames. The positioning lifting rod and the caster wheel are all mounted on the fixed feet.

[0007] Preferably, the guide rail has grooves on both sides of its sidewalls;

[0008] The actuator includes a slider, a connecting rod, and a traction block. The slider is slidably embedded in the guide rail. The slider is rotatably connected to the connecting rod via a shaft. The shaft between the slider and the connecting rod moves through the slide groove. The traction block is rotatably connected to the lower end of the connecting rod away from the slider via a shaft. The connecting rod is slidably connected to the lower end of the crossbeam.

[0009] Preferably, the drive structure includes a traction rope, a rope reel, and a handwheel;

[0010] One end of the traction rope is fixed to one side of the traction block, and the other end of the traction rope is wound on the rope reel. The handwheel is connected to the rope reel via a shaft. The rope reel is rotatably connected to the crossbeam via a bracket and is located below the crossbeam.

[0011] Preferably, the handwheel and the rope reel are both installed on the end of the guide rail away from the slag box, and the lower part of the crossbeam near the slag box is rotatably connected to the reversing wheel through the bracket, and the middle of the traction rope passes around the reversing wheel and changes direction.

[0012] Preferably, wedge-shaped holes are provided on the side walls of both sides of the guide rail near the slag box;

[0013] Fine-tuning guide blocks are movably installed in both wedge-shaped holes. The two fine-tuning guide blocks are fixedly connected to the outside of the linkage plate. An ear block is fixed on one side of the linkage plate. A tie bolt is screwed onto the ear block. A through hole is provided on the end frame for the tie bolt stud part to move through. The nut part of the tie bolt is pressed against the side wall of the end frame away from the fine-tuning guide block.

[0014] The horizontal cross-sections of the fine-tuning guide block and the wedge hole are both wedge-shaped and compatible. When one of the fine-tuning guide blocks is engaged with the wedge hole on one side, the other fine-tuning guide block is separated from the wedge hole on the other side. At this time, the wedge end of one of the fine-tuning guide blocks extends into the guide rail and forms a gap with the other side of the guide rail that is the same as the width of the graphite strip.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. In this utility model, by setting up a guide rail, a top moving part, and a driving structure, the operator only needs to drive the top moving part to slide through the driving structure, which will cause the top moving part to move multiple graphite strips placed in the guide rail, so that the graphite strips can be inserted into the slag box in sequence to complete the graphite strip filling operation. Compared with the traditional method of manually inserting graphite strips, this is safer and more reliable. In addition, the graphite strip filling equipment of the tin bath transition roller improves the efficiency of inserting graphite strips each time, greatly shortens the opening time of the slag box, reduces the time for external oxygen to enter the tin bath, reduces the contamination of molten tin, and reduces quality defects such as white spots on glass.

[0017] 2. In this utility model, by setting the reversing wheel, the traction rope can be folded back and reversed, thereby enabling the handwheel and the rope winding wheel to be installed on the end of the guide rail away from the slag box. At the same time, it can also meet the requirement of driving the traction block to move from the end away from the slag box to the end of the slag box. This allows the operator to stay away from the slag box during operation, avoid the harm caused by the high temperature environment to the operator, and improve the comfort of the operator when filling graphite strips.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Reference Figures 1-4 The graphite strip filling device for the tin bath transition roller shown includes a support frame 1. The support frame 1 includes end frames 11, crossbeams 12 and fixed feet 13. Two end frames 11 are provided and fixed to both ends of the crossbeams 12 respectively. The upper end of the crossbeams 12 is fixed to the lower end of the guide rail 2. Four fixed feet 13 are provided and fixed symmetrically in pairs on both sides of the lower end of the two end frames 11. The upper end of the support frame 1 is fixed with a guide rail 2 for placing graphite strips. The guide rail 2 is a U-shaped track. A pusher 3 for driving the graphite strips to move on the guide rail 2 is installed inside the guide rail 2. A drive structure 4 for driving the pusher 3 to move is also installed at the lower end of the guide rail 2.

[0026] The lower end of the support frame 1 is equipped with a positioning lifting rod 5 and a caster wheel 6. Both the positioning lifting rod 5 and the caster wheel 6 are mounted on the fixed foot block 13. Specifically, the positioning lifting rod 5 is connected to the fixed foot block 13 through a threaded structure. The lower end of the positioning lifting rod 5 is threaded through the fixed foot block 13 and is fixed with a support foot 51.

[0027] Based on the above structure, during use, the operator can use the casters 6 to move the graphite strip filling equipment of the tin bath transition roller, so that the guide rail 2 corresponds to the position of the slag box opening. By rotating the positioning lifting rod 5, the overall height of the equipment can be adjusted, that is, the height of the guide rail 2 can be adjusted to adapt to slag boxes of different heights, improving its flexibility during use. When the guide rail 2 is fully aligned with the slag box opening, the operator only needs to drive the top moving part 3 to slide through the drive structure 4, so that the top moving part 3 can drive the multiple graphite strips placed in the guide rail 2 to move, so that the graphite strips can be inserted into the slag box in sequence, completing the graphite strip filling operation. Compared with the traditional method of manually inserting graphite strips, it is safer and more reliable. In addition, the graphite strip filling equipment of the tin bath transition roller improves the efficiency of inserting graphite strips each time, greatly shortens the opening time of the slag box opening, reduces the time for external oxygen to enter the tin bath, reduces the contamination of molten tin, and reduces quality defects such as white spots on glass.

[0028] Furthermore, the guide rail 2 has grooves 21 on both sides of its sidewalls;

[0029] The top actuator 3 includes a slider 31, a connecting rod 32, and a pulling block 33. The slider 31 is slidably embedded in the guide rail 2. The slider 31 is rotatably connected to the connecting rod 32 through a shaft. The shaft between the slider 31 and the connecting rod 32 movably passes through the slide groove 21. The pulling block 33 is rotatably connected to the lower end of the connecting rod 32 away from the slider 31 through a shaft. The connecting rod 32 is slidably connected to the lower end of the crossbeam 12.

[0030] The drive structure 4 includes a traction rope 41, a rope winding wheel 42, and a handwheel 43. One end of the traction rope 41 is fixed to one side of the traction block 33, and the other end of the traction rope 41 is wound around the rope winding wheel 42. The handwheel 43 is connected to the rope winding wheel 42 via a shaft. The rope winding wheel 42 is rotatably connected to the crossbeam 12 via a bracket and is located below the crossbeam 12.

[0031] The operator only needs to turn the handwheel 43 to drive the rope winding wheel 42 to rotate, thereby winding the traction rope 41. The traction rope 41 drives the slider 31 to slide through the traction block 33 and the connecting rod 32, thereby achieving the purpose of using the slider 31 to drive the graphite strip to slide along the guide rail 2, and completing the operation of filling the slag box with graphite strips.

[0032] Furthermore, both the handwheel 43 and the rope reel 42 are installed on the end of the guide rail 2 away from the slag box. The lower part of the crossbeam 12 near the slag box is rotatably connected to the reversing wheel 7 via a bracket. The middle part of the traction rope 41 passes around the reversing wheel 7 and reverses direction.

[0033] By setting the reversing wheel 7, the traction rope 41 can be folded back and reversed, so that the handwheel 43 and the rope winding wheel 42 can be installed on the end of the guide rail 2 away from the slag box. At the same time, it can also meet the need to drive the traction block 33 from the end away from the slag box to the end of the slag box. This allows the workers to stay away from the slag box during operation, avoid the harm caused by the high temperature environment to the workers, and improve the comfort of the workers when filling graphite strips.

[0034] Furthermore, wedge-shaped holes 22 are provided on the side walls of the guide rail 2 near the slag box on both sides;

[0035] Fine-tuning guide blocks 8 are movably installed in both wedge-shaped holes 22. The two fine-tuning guide blocks 8 are fixedly connected to the outside of the linkage plate 81. An ear block 82 is fixed on one side of the linkage plate 81. A tie bolt 9 is screwed onto the ear block 82. A through hole 111 is opened on the end frame 11 for the stud part of the tie bolt 9 to move through. The nut part of the tie bolt 9 is pressed against the side wall of the end frame 11 away from the fine-tuning guide block 8. The horizontal cross section of the fine-tuning guide block 8 and the wedge-shaped hole 22 are both wedge-shaped and adapted to each other.

[0036] During use, the operator can loosen the tie bolt 9 to separate the nut part of the tie bolt 9 from the side wall of the end frame 11, and then adjust the position of the fine adjustment guide block 8 so that the two fine adjustment guide blocks 8 cooperate with each other to adjust the lateral position of the graphite strip. This allows for lateral adjustment of the position of the graphite strip entering the slag box opening within a small range, making the position of the graphite strip and the slag box opening more accurate and improving the filling accuracy.

[0037] It should be noted that the spacing between the two fine-tuning guide blocks 8 is consistent with the width of the graphite strip, and when one of the fine-tuning guide blocks 8 is engaged with the wedge-shaped hole 22 on one side, the other fine-tuning guide block 8 is separated from the wedge-shaped hole 22 on the other side. At this time, the wedge-shaped end of one of the fine-tuning guide blocks 8 extends into the guide rail 2 and forms a gap with the other side of the guide rail 2 that is the same as the width of the graphite strip.

[0038] The working principle of this utility model is as follows: During daily use, the operator can use the casters 6 to move the graphite strip filling device for the tin bath transition roller, aligning the guide rail 2 with the slag box opening. The overall height of the device, i.e., the height of the guide rail 2, can be adjusted by rotating the positioning lifting rod 5 to accommodate slag boxes of different heights, improving its flexibility during use. Once the guide rail 2 is fully aligned with the slag box opening, the operator only needs to rotate the handwheel 43 to drive the rope winding wheel 42, thereby winding up the traction rope 41, thus enabling the traction... The guide rope 41 drives the slider 31 to slide through the traction block 33 and the connecting rod 32, thereby enabling the slider 31 to move multiple graphite strips placed in the guide rail 2, so that the graphite strips can be inserted into the slag box in sequence to complete the graphite strip filling operation. Compared with the traditional method of manually inserting graphite strips, this is safer and more reliable. In addition, the graphite strip filling equipment of the tin bath transition roller improves the efficiency of each graphite strip insertion, greatly shortens the opening time of the slag box, reduces the time for external oxygen to enter the tin bath, reduces the contamination of molten tin, and reduces quality defects such as white spots on glass.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
