[0003] In the lithium battery manufacturing industry, vibratory rollers can be used in the battery electrode rolling process and other applications requiring vibration compaction.

Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0027] Specific reference Figure 1 , Figure 3 , Figure 4 and Figure 5 This utility model provides:
[0028] A single-cylinder vertical vibrating roller includes a first roller head 1, a second roller head 2, and a cylinder 3 fixedly connected between the first roller head 1 and the second roller head 2. The cylinder 3 has a through inner cavity 30. At both ends of the inner cavity 30, a first rotating disk 41 and a second rotating disk 42 rotatable relative to the cylinder 3 are respectively provided. A first rotating shaft 51 and a second rotating shaft 52 rotatable relative to the first rotating disk 41 and the second rotating disk 42 are provided between the first rotating disk 41 and the second rotating disk 42. A first eccentric wheel 511 is provided on the first rotating shaft 51, and a second eccentric wheel 521 is provided on the second rotating shaft 52. The first rotating shaft 51 and the second rotating shaft 52 are... The first rotating disk 41 and the second rotating disk 42 are symmetrically arranged. A counterweight 6 is provided in the inner cavity 30 of the cylinder 3. The counterweight 6 is directly or indirectly fixedly connected to the first rotating disk 41 and the second rotating disk 42. A drive shaft 50 is rotatably arranged inside the first roller head 1. The inner end of the drive shaft 50 is connected to the first end of the first rotating shaft 51 through a first gear set. The second end of the first rotating shaft 51 is connected to the second end of the second rotating shaft 52 through a second gear set. The transmission ratio of the second gear set is 1. The drive shaft 50 can drive the first rotating shaft 51 to rotate through the first gear set and further drive the second rotating shaft 52 to rotate through the second gear set.
[0029] Reference Figure 3 , Figure 4 In practical applications, an external drive device is fixed to the outer end of the drive shaft 50 and drives the drive shaft 50 to rotate. The drive shaft 50 drives the first rotating shaft 51 to rotate through a first gear set, and the first rotating shaft 51 drives the second rotating shaft 52 to rotate through a second gear set. Since the transmission ratio of the second gear set is 1, the first rotating shaft 51 and the second rotating shaft 52 rotate at the same speed but in opposite directions. Therefore, when the first rotating shaft 51 and the second rotating shaft 52 drive the first eccentric wheel 511 and the second eccentric wheel 521 to rotate respectively, the vibrations of the first eccentric wheel 511 and the second eccentric wheel 521 cancel each other out in the horizontal direction and superimpose their vibrations in the vertical direction, thus achieving unidirectional vertical vibration. In addition, by setting a counterweight 6, the vibration direction can be ensured to be vertical, ensuring that the vibration is output vertically downward. On the other hand, this type of single-cylinder vertical vibrating roller uses a single cylinder 3 to install all internal components, effectively simplifying the structure, saving volume, and occupying less space.
[0030] Reference Figure 3 , Figure 4In some embodiments, the inner cavity 30 of the cylinder 3 is further provided with a plurality of intermediate rotating disks 43 that can rotate relative to the cylinder 3. The first rotating shaft 51 and the second rotating shaft 52 pass through the intermediate rotating disks 43 and can rotate relative to the intermediate rotating disks 43. The intermediate rotating disks 43 divide the space of the inner cavity 30 between the first rotating disk 41 and the second rotating disk 42 into a plurality of spaced cavities. The first eccentric wheel 511, the second eccentric wheel 521 and the counterweight 6 are disposed in the spaced cavities. The number of intermediate rotating disks 43 can be selected according to specific needs. The intermediate rotating disks 43 provide intermediate support for the first rotating shaft 51 and the second rotating shaft 52, preventing the first rotating shaft 51 and the second rotating shaft 52 from deforming due to the eccentricity of the eccentric wheels.
[0031] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, the number of the first eccentric wheels 511 and the number of the second eccentric wheels 521 are the same as the number of the spacer cavities. The counterweight 6 is fixed to the side wall of the first rotating disk 41, the side wall of the second rotating disk 42, and the side wall of the intermediate rotating disk 43. The first rotating disk 41, the second rotating disk 42, and the intermediate rotating disk 43 are rotatably mounted in the inner cavity 30 of the cylinder 3 via the first outer bearing 71, the second outer bearing 72, and the intermediate outer bearing 73, respectively. The first rotating shaft 51 is rotatably connected to the first rotating disk 41, the second rotating disk 42, and the intermediate rotating disk 43 via the first inner bearing 81, the second inner bearing 82, and the third inner bearing 83, respectively. The second rotating shaft 52 is rotatably connected to the first rotating disk 41, the second rotating disk 42, and the intermediate rotating disk 43 via the fourth inner bearing 84, the fifth inner bearing 85, and the sixth inner bearing 86, respectively. The rotation function of the first rotating disk 41, the second rotating disk 42, and the middle rotating disk 43 can be ensured by the first outer bearing 71, the second outer bearing 72, and the middle outer bearing 73. With the help of the counterweight 6, the entire single-cylinder vertical vibrating roller can output vibration vertically downward.

The inner rings of the first inner bearing 81 and the third inner bearing 83, the inner rings of the second inner bearing 82 and the third inner bearing 83, and the two inner rings of the third inner bearing 83 are mutually limited by the first eccentric wheel 511; the inner rings of the fourth inner bearing 84 and the sixth inner bearing 86, the inner rings of the fifth inner bearing 85 and the sixth inner bearing 86, and the two inner rings of the sixth inner bearing 86 are mutually limited by the second eccentric wheel 521.

[0034] Reference Figure 3 , Figure 4 In some embodiments, the first gear set includes a first driving gear 91 mounted on the inner end of the drive shaft 50 and a first driven gear 92 disposed at the first end of the first rotating shaft 51. The first driving gear 91 and the first driven gear 92 mesh with each other. The drive shaft 50 can drive the first rotating shaft 51 to rotate via the first driving gear 91 and the first driven gear 92, and further drive the first eccentric wheel 511 to rotate via the first rotating shaft 51. The second gear set includes a second driving gear 93 mounted on the second end of the first rotating shaft 51 and a second driven gear 94 mounted on the second end of the second rotating shaft 52. The second driving gear 93 and the second driven gear 94 mesh with each other. The first rotating shaft 51 can drive the second rotating shaft 52 to rotate via the second driving gear 93 and the second driven gear 94, and further drive the second eccentric wheel 521 to rotate via the second rotating shaft 52. In this embodiment, the first driving gear 91, the first driven gear 92, the second driving gear 93, and the second driven gear 94 can be spur gears or helical gears. In some other embodiments, three or more gear sets may be used to achieve the transmission function of the first gear set and the second gear set.
[0035] Reference Figure 3-5In some embodiments, the perpendicular segment between the central axis of the first rotating shaft 51 and the central axis of the second rotating shaft 52 is called the perpendicular plane N. The first eccentric wheel 511 and the second eccentric wheel 521 are symmetrically arranged with respect to the perpendicular plane N, and the center of gravity of the counterweight 6 is located on the perpendicular plane N. In actual operation, the first eccentric wheel 511 and the second eccentric wheel 521 are always symmetrical with respect to the perpendicular plane N. The symmetry of the center of gravity of the first eccentric wheel 511 and the center of gravity of the second eccentric wheel 521 with respect to the perpendicular plane N ensures that horizontal vibrations are canceled out during operation.
