The drive worm gear drives the driven worm wheel to rotate, effectively reducing the rotation speed and preventing excessive filling.

Description

Technical Field

[0001] This utility model relates to the field of lubrication mechanism technology, and in particular to a lubrication mechanism for preventing kiln rollers from jamming. Background Technology

[0002] In the industrial production of high-temperature products such as ceramics and glass, kiln rollers play a crucial role in material transport, and their stability and reliability directly affect product quality and production efficiency.

[0003] The kiln rollers are rotatably connected to the roller frame via bushings. To prevent jamming, high-temperature grease needs to be manually added periodically. However, this manual method has the following problems:

[0004] Manual, periodic addition of grease is inconvenient to control the amount added. Adding too much at once will lead to waste, causing excessive grease to be squeezed out, adhere to dust, and clump together, affecting rotation. Adding too little will require frequent replenishment, affecting work efficiency. Therefore, a lubrication structure that can automatically and continuously replenish small amounts is needed.

A support bracket 4 is fixedly connected to the outer wall of the roller frame 1 at a position corresponding to the central shaft of the conveying roller 2. The driving worm gear 5 is rotatably connected to the middle of the support bracket 4. Support plates 6 are fixedly connected to both sides of the middle of the bottom surface of the inner wall of the support bracket 4. The middle of the two support plates 6... A rotating shaft 12 is rotatably connected to the support plate 6. One end of the rotating shaft 12 passes through the outer wall of the support plate 6 and is fixedly connected to a rotating disk 10. A plunger pump 8 is fixedly connected to the middle of one side of the bottom surface of the inner wall of the support bracket 4. A connecting rod 11 is rotatably connected to the telescopic end of the plunger pump 8. The end of the connecting rod 11 away from the plunger pump 8 is rotatably connected to the outer edge of the rotating disk 10. A filling pipe 7 is fixedly connected to the output end of the plunger pump 8. The output end of the filling pipe 7 is fixedly connected to and communicates with the grease inlet of the bushing 3. A driven worm gear 13 is fixedly connected to the middle of the rotating shaft 12. The driven worm gear 13 is meshed with the drive worm 5.

[0025] As an optional technical solution of this utility model, a grease storage tank 9 is fixedly connected to one side of the bottom surface of the support bracket 4, and a suction tube is fixedly connected to the suction end of the plunger pump 8. The suction tube is located at the bottom of the inner wall of the grease storage tank 9, so that the grease in the inner wall of the grease storage tank 9 can be completely extracted during the pumping process of the plunger pump 8.

[0026] As an optional technical solution of this utility model, the length of the connecting rod 11 is greater than the diameter of the rotating disk 10, the diameter of the rotating disk 10 is less than the extension stroke of the plunger pump 8, and the bottom of the rotating disk 10 is higher than the top of the plunger pump 8, so as to prevent the pulling process of the connecting rod 11 driven by the rotating disk 10 from exceeding the internal range of the plunger pump 8.

[0027] As an optional technical solution of this utility model, the driven worm wheel 13 is positioned corresponding to the middle of the driving worm 5. The driven worm wheel 13 is located at the center between the two support plates 6. The bottom of the driven worm wheel 13 is higher than the bottom surface of the inner wall of the support bracket 4, thereby preventing contact interference between the driven worm wheel 13 and the bottom surface of the inner wall of the support bracket 4.

[0029] The following steps are required when using the kiln roller anti-jamming lubrication mechanism:

[0030] 1) The conveying roller 2 drives the drive worm 5 to rotate during the working rolling process, which in turn drives the driven worm wheel 13 to rotate;

[0031] 2) The driven worm gear 13 rotates, which in turn drives the rotating shaft 12 to rotate, which drives the rotating disk 10 to rotate, and then drives the extension end of the plunger pump 8 to press up and down in a cycle through the connecting rod 11.

[0032] 3) The lubricating grease is automatically added into the inside of the bushing 3 through the filling pipe 7, realizing automated filling. As the conveying roller 2 rotates, a small amount of lubricating grease is continuously added.

[0033] In summary, the conveyor roller 2 drives the drive worm 5 to rotate during its rolling motion, which in turn drives the driven worm wheel 13 to rotate, which in turn drives the rotating shaft 12 to rotate, which in turn drives the rotating disk 10 to rotate. This, in turn, drives the extension end of the plunger pump 8 to press up and down cyclically via the connecting rod 11. Lubricating grease is automatically added to the inside of the bushing 3 through the filling pipe 7, achieving automated filling. As the conveyor roller 2 rotates, a small amount of lubricating grease is continuously added, thereby effectively controlling the amount of lubricating grease, maintaining lubrication, and improving convenience. The drive worm 5 drives the driven worm wheel 13 to rotate, which can effectively reduce the rotation speed, reduce the filling speed, and prevent excessive filling.
