DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 4 As shown, a graphite crystallizer oiling device includes a fixed seat 1 and two brushes 2. The fixed seat 1 is provided with a dual-axis linear module 3. The two brushes 2 are synchronously rotated and arranged on the second slider of the dual-axis linear module 3. The oiling device also includes a fixing mechanism, which includes a support frame 4, an annular bracket 5, a plurality of pneumatic cylinders 6, and a suction cup 61. The support frame 4 is provided on the fixed seat 1 and is located to the side of the brush 2. The annular bracket 5 is provided on the support frame 4. The plurality of pneumatic cylinders 6 are evenly slidably provided on the support frame 4 and the plurality of pneumatic cylinders 6 are arranged in an annular shape. The plurality of pneumatic cylinders 6 are respectively fixedly connected to the plurality of suction cups 61. The plurality of suction cups 61 are all facing the annular bracket 5 and the heads of the plurality of suction cups 61 can penetrate into the interior of the annular bracket 5. Generally, the graphite crystallizer is fixedly connected to the water-cooled jacket. The oiling device of this embodiment is to oil the inner wall of the graphite crystallizer.

[0022] The graphite crystallizer can be placed inside the annular support 5, and the support frame 4 and the annular support 5 support the graphite crystallizer. Multiple pneumatic cylinders 6 slide and start, driving the heads of multiple suction cups 61 to suck the outer wall of the graphite crystallizer, so that the graphite crystallizer remains stable on the annular support 5.

[0023] The two brushes 2 are oiled, and then the dual-axis linear module 3 is started, first driving the two brushes 2 to slide forward so that the two brushes 2 are aligned with the graphite crystallizer, and then driving the two brushes 2 to slide to the left so that the two brushes 2 penetrate into the graphite crystallizer sleeve, and the inner wall of the graphite crystallizer sleeve contacts the two brushes 2, and the two brushes 2 rotating synchronously realize oiling the inner wall of the graphite crystallizer.

[0024] After oiling the graphite crystallizer, the dual-axis linear module 3 drives the two brushes 2 to slide to the right, separating the graphite crystallizer from the two brushes 2. Then the pneumatic cylinder 6 drives the suction cup 61 to loosen the outer wall of the graphite crystallizer, and the worker can take the graphite crystallizer out from the inside of the annular bracket 5.

[0025] The oiling device of this embodiment replaces manual oiling and realizes automatic oiling of the inner wall of the graphite crystallizer, thereby improving the oiling efficiency and saving manpower.

[0026] In one embodiment, the fixing mechanism further includes multiple telescopic cylinders 7, which are evenly arranged on the support frame 4 in a circular arrangement. The telescopic rod of each telescopic cylinder 7 is fixedly connected to the housing of the pneumatic cylinder 6. When the telescopic cylinders 7 are activated, they move the pneumatic cylinder 6 and the suction cups 61 toward the graphite crystallizer, allowing the heads of the suction cups 61 to penetrate the interior of the annular support 5. When the pneumatic cylinder 6 is activated, the heads of the multiple suction cups 61 adhere to the outer wall of the graphite crystallizer.

[0027] In one embodiment, the annular support 5 includes two ring frames 51 and multiple straight rods 52. The two ring frames 51 are fixedly connected to the support frame 4, and the multiple straight rods 52 are evenly fixedly connected between the two ring frames 51. The multiple straight rods 52 are arranged in a ring shape. The heads of the multiple suction cups 61 can pass through the gaps between two adjacent straight rods 52 to the inside of the multiple straight rods 52. Specifically, the multiple pneumatic cylinders 6 slide and start, driving the heads of the multiple suction cups 61 through the multiple gaps, thereby adsorbing the outer wall of the graphite crystallizer.

[0028] As an embodiment, the oiling device further includes an oil storage barrel 8, which is mounted on the support frame 4 and located to the side of the annular bracket 5, with the opening of the oil storage barrel 8 facing the brushes 2. A small amount of oil is stored within the oil storage barrel 8 (the oil level is lower than the level of the opening of the oil storage barrel 8). The two brushes 2 rotate synchronously, and then the dual-axis linear module 3 is activated, first driving the two brushes 2 to slide backward, so that the two brushes 2 face and align with the opening of the oil storage barrel 8. It then drives the two brushes 2 to slide leftward, allowing them to penetrate the oil storage barrel 8. The rotating brushes 2 come into contact with the oil inside the oil storage barrel 8 and are coated with the oil, thereby applying the oil to the brushes 2. At this point, the annular bracket 5 is in a shutdown state.

[0029] In one embodiment, the dual-axis linear module 3 includes a first linear module 31 and a second linear module 32. The first linear module 31 is mounted on a fixed base 1. The first slider of the first linear module 31 is fixedly connected to the base of the second linear module 32 and can drive both to slide left and right. When the first linear module 31 is activated, it drives the second linear module 32 and the two brushes 2 mounted thereon to slide left and right. When the second linear module 32 is activated, it drives the two brushes 2 to slide back and forth.

[0030] In one embodiment, the second slider is provided with a rotary motor 91, the output shaft of which is fixedly connected to the fixed plate 9. Two threaded blocks 93 are slidably provided on the fixed plate 9, and the two threaded blocks 93 slide relative to each other. Each of the threaded blocks 93 is provided with a fixing rod, and the two brushes 2 are respectively mounted on the two fixing rods. When the rotary motor 91 is activated, it drives the fixed plate 9 to rotate, thereby driving the two brushes 2 to rotate synchronously. Simultaneously, the relative sliding of the two threaded blocks 93 drives the two brushes 2 to slide relative to each other, increasing or decreasing the distance between the two brushes 2, allowing the brushes 2 to oil graphite crystallizers of different sizes.

[0031] As an embodiment, the fixed plate 9 is provided with two bearing seats relative to each other, and a rotating rod 92 is rotatably connected between the two bearing seats. The rotating rod 92 is fixedly connected to the bearings on the bearing seats to achieve rotation. The rotating rod 92 is provided with two threaded segments with opposite threads, and the two threaded segments are respectively threadedly connected to two threaded blocks 93. The fixed plate 9 is provided with an inverted U-shaped limit rod 95, and the two fixed rods are positioned between the limit rod 95 and the fixed plate 9. The fixed plate 9 is provided with a drive motor 94, and the output shaft of the drive motor 94 is fixedly connected to one end of the rotating rod 92 passing through the bearing seat. The limit rod 95 and the fixed plate 9 limit the position of the fixed rod, and thus limit the sliding direction of the threaded block 93. When the drive motor 94 is started, it drives the two threaded blocks 93 to slide on the two threaded segments respectively, and the two threaded blocks 93 slide relative to each other, thereby causing the two brushes 2 to slide relative to each other, and the distance between the two brushes 2 increases or decreases. The oil brushing device operates as follows: a small amount of oil is stored in the oil barrel 8, and two brushes 2 rotate synchronously on the fixed base 1. The second linear module 32 is then activated, first driving the two brushes 2 to slide backward, so that they face and align with the barrel opening of the oil barrel 8. The first linear module 31 is activated and drives the two brushes 2 to slide leftward, allowing them to penetrate the oil barrel 8. The rotating brushes 2 come into contact with the oil inside the oil barrel 8 and are coated with oil. The first linear module 31 then drives the two brushes 2 to slide rightward, separating the oil barrel 8 from the two brushes 2.

[0032] The graphite crystallizer is placed inside the annular bracket 5. The telescopic cylinder 7 is activated, driving the pneumatic cylinder 6 and the suction cup 61 toward the graphite crystallizer, allowing the head of the suction cup 61 to penetrate the annular bracket 5. The pneumatic cylinder 6 then drives the head of the suction cup 61 to suck the outer wall of the graphite crystallizer. The second linear module 32 then drives the two brushes 2 to slide forward, aligning the two brushes 2 with the graphite crystallizer. The first linear module 31 then drives the two brushes 2 to slide leftward, allowing the two brushes 2 to penetrate the graphite crystallizer sleeve. The inner wall of the graphite crystallizer sleeve contacts the two brushes 2, and the two rotating brushes 2 apply oil to the inner wall of the graphite crystallizer.

[0033] The embodiments described above are only preferred embodiments of the present invention and are only used to explain the present invention, not to limit the scope of implementation of the present invention. For those skilled in the art, it is of course possible to easily make other implementation methods by replacing or changing the technical content disclosed in this specification.
