[0021] This utility model embodiment provides a centrifugal screening device for dye particles, such as Figure 1-4 As shown, the device includes a housing 1, with a torque motor 2 fixedly installed at the bottom of the housing 1. The housing 1 contains multiple screening cylinders 3 arranged in a concentric circle. The drive shaft of the torque motor 2 is fixedly connected to the screening cylinders 3. The torque motor 2 drives the screening cylinders 3 to rotate, achieving the purpose of centrifugal screening.

[0022] Multiple insertion tubes 31 are welded in a ring on the surface of the screening cylinder 3. The insertion tubes 31 are distributed longitudinally along the surface of the screening cylinder 3. Multiple sets of through screening holes 32 are opened on the surface of the screening cylinder 3. Each set of screening holes 32 is arranged longitudinally at equal intervals, and the multiple sets of screening holes 32 correspond one-to-one with the multiple insertion tubes 31. The diameter of the screening holes 32 in the screening cylinder 3 gradually decreases from the inside to the outside.

[0023] It also includes a rubber strip 33, which corresponds one-to-one with the insertion tube 31. The rubber strip 33 is inserted into the insertion tube 31 and can divide the screening hole 32 into two.

[0024] A cover 4 is fixedly installed on the top of the box body 1. Multiple extension plates 41 are connected to the top of the inner wall of the cover 4, and each extension plate 41 corresponds to a screening cylinder 3. When the cover 4 is fixed to the box body 1, the extension plates 41 contact the upper edge of the inner wall of the screening cylinder 3, thus sealing the box and preventing dye particles from leaking out.

[0025] It also includes a hollow vibrating ring 5, which is distributed on the surface of the screening cylinder 3. The inner hole of the vibrating ring 5 is a screening hole 32. The vibrating ring 5 is equipped with a striking component, which causes the vibrating ring 5 to vibrate repeatedly at a certain frequency.

[0026] The striking assembly includes a slide bar 51, a striking rod 52, a spring 53, a small magnet 54, and a small magnetic block 55. The slide bar 51 is arranged symmetrically up and down, and the striking rod 52 is arranged symmetrically left and right. The end of the slide bar 51 passes through the end of the striking rod 52 and is welded to the inner wall of the vibration ring 5. The end of the slide bar 51 and the end of the striking rod 52 slide in a sliding fit.

[0027] Spring 53 is sleeved on the outside of slide bar 51 and abuts against the end of striking bar 52. Small magnet 55 is fixedly installed at the end of striking bar 52, and small magnet 54 is located between two adjacent striking bars 52.

[0028] A battery, a microcontroller, and a small motor are fixedly installed inside the vibration ring 5. The battery, microcontroller, and small motor are electrical components. A small magnet 54 is fixedly installed to the drive shaft of the small motor.

[0029] As shown in the attached diagram, the N pole of the small magnetic block 55 faces to the left. During the rotation of the small magnet 54, when the N pole of the small magnet 54 faces to the left, the striking rods 52 are drawn closer together due to the magnetic force; when the N pole of the small magnet 54 faces to the right, the striking rods 52 are moved away from each other due to the magnetic force. During their movement, the striking rods 52 collide with the inner wall of the vibrating ring 5, causing the vibrating ring 5 to vibrate.

[0030] The drive shaft of the torque motor 2 runs vertically through the housing 1 and the screening cylinder 3. The shaft of the torque motor 2 is symmetrically welded with limit blocks 21. The bottom of the screening cylinder 3 is provided with a groove that matches the limit block 21. The limit block 21 is provided with a clamping strip 22 on the outside. The end of the clamping strip 22 is bent downward and contacts the bottom layer of the innermost screening cylinder 3.

[0031] The torque motor 2 is provided with a bolt 23 on the outside. The bolt 23 is threadedly connected to the bolt 23. One end of the bolt 23 passes through the clamping strip 22 and is threadedly connected to the limit block 21.

[0032] The limiting block 21 is located above the housing 1. It is fixed in place by snap-fit, allowing the torque motor 2 to drive the screening cylinder 3 to rotate when it is working. The limiting block 21 and bolts 23 are used to fix the screening cylinder 3 in place.

[0033] In summary, this centrifugal dye particle screening device consists of a housing 1, a torque motor 2, a screening cylinder 3, a housing cover 4, and a vibrating ring 5. Through the cooperation of the insertion tube 31 and the rubber strip 33, the rubber strip 33 divides the screening hole 32 in two, thereby adjusting the screening hole diameter and improving screening accuracy. Furthermore, the screening cylinder 3 is equipped with a vibrating ring 5, which repeatedly vibrates to prevent dye particles from getting stuck in the screening holes, thus preventing clogging. It also prevents small dye particles from overlapping and sticking together, thus avoiding them being unable to pass through the corresponding screening holes.
