Technical Field
[0001] The utility model relates to the technical field of rubber pre-processing, in particular to a rubber pre-dispersing auxiliary agent screening device. Background Art
[0002] During the production and processing of rubber, dispersing aids are usually required for auxiliary processing. Pre-dispersing aids are important processing auxiliary preparations. During the production and processing of dispersing aids, the processed dispersing aids need to be filtered and screened to prevent particles that are too large or other foreign matter generated during the production process from being filtered out, thereby ensuring the production and processing quality of the dispersing aids.
[0003] Chinese patent document CN217411458U discloses a rubber pre-dispersing agent screening device, in which the dispersing agent flows into the shell through a feed pipe and is dispersed onto a filter plate under the guidance of the flow distribution of a distribution pipe and supported by the filter plate, so as to prevent the dispersing agent from being concentrated and accumulated on the filter plate. The sieve holes on the filter plate are used to screen and separate dispersing agents of different sizes. The filter plate moves toward or away from a pressing plate in a vertical direction along a guide rail under the drive of a motor and the transmission of a gear rack. Pressing teeth are provided on the surface of the pressing plate facing the filter plate, and the pressing teeth can eject debris embedded in the sieve holes to prevent the filter plate from being blocked, thereby improving the screening performance of the dispersing agent, preventing the dispersing agent or debris with larger particles from being transported outward, and ensuring the processing of the dispersing agent.
[0004] Since the filter plate structure in the above screening device moves under the action of gears and racks, the filter plate mainly moves back and forth at a uniform speed during movement, and the dispersing aid cannot be frequently shaken on the top of the filter plate, so there are certain limitations.

[0023] The shaking unit includes a shaking plate 501, a bent rod 502, a spring 503 and a screening plate 504. The shaking plate 501 is installed on the inner wall of the shell 1, and the outer wall of the shaking plate 501 is slidably connected to the inner wall of the shell 1, and the shaking plate 501 can slide inside the shell 1. The bent rod 502 is fixedly connected to the inner wall of the shell 1, and the bent rod 502 passes through the outside of the shaking plate 501 and extends to the outside of the shaking plate 501. The outer wall of the bent rod 502 is slidably connected to the inner wall of the shaking plate 501, and the shaking plate 501 can slide on the outer wall of the bent rod 502. The spring 503 is installed on the outer wall of the bent rod 502, and the top of the spring 503 is connected to the bottom of the shaking plate 501. The spring 503 can support the shaking plate 501, and the screening plate 504 is fixedly connected to the inner wall of the shaking plate 501.
[0024] By setting the shaking plate 501 and the spring 503, when a large amount of pre-dispersing aid enters the interior of the shell 1 through the feed pipe and flows to the top of the shaking plate 501 through the guide plate 4, pressure will be generated on the shaking plate 501, causing the shaking plate 501 to slide on the outer wall of the bent rod 502 and exert pressure on the spring 503. After the spring 503 absorbs the impact force, the spring 503 will push the shaking plate 501 to reset. The frequent displacement of the shaking plate 501 can ensure the fluidity of the pre-dispersing aid at the top of the shaking plate 501 and ensure the screening effect of the pre-dispersing aid.
[0025] The rotating unit includes a motor 505, an output rod 506, a gear set 507, a second curved rod 508, a sleeve 509 and a scraper 510. The motor 505 is fixedly connected to the bottom of the shaking plate 501, the output rod 506 is installed at the output end of the motor 505, the gear set 507 is arranged below the screening plate 504, one end of the output rod 506 is connected to the gear set 507 in a transmission manner, the second curved rod 508 is installed on the top of the screening plate 504, and the bottom end of the second curved rod 508 passes through the screening plate 504 and is connected to the gear set 507 in a transmission manner.
