The raw material is poured into the box 501, and the active roller 504 and the driven roller 505 rotate relative to each other along the inner cavity of the box 501, so that the ethyl acrylate raw material is crushed when passing through the gap between the active roller 504 and the driven roller 505, thereby reducing the particle size of the raw material. The raw material is screened by the filter plate 506, and particles that are not conducive to the stirring and mixing of the reactor body 1 are blocked. Particles that are conducive to the stirring and mixing of the reactor body 1 pass through the filter plate 506 and are poured into the inner cavity of the reactor body 1 through the discharge pipe 502.

The elastic scraper 18 is provided. There are two groups of elastic scrapers 18, which correspond to the active roller 504 and the driven roller 505 respectively, and are connected to the inner wall of the box 501 through the connecting plate 17. The elastic scraper 18 can scrape off the raw materials attached to the surface of the active roller 504 and the driven roller 505 to ensure the integrity of the raw materials.

The transmission belt 16 rotates and drives the driven wheel 15 at the other end to rotate. The driven wheel 15 is coaxially fixedly connected to the driving gear 12. Therefore, the driven wheel 15 rotates and drives the driving gear 12 to rotate. Since the teeth of the driving gear 12 and the teeth of the driven gear 13 are meshed with each other, the driving roller 5 is driven through the cooperation of the driving gear 12 and the driven gear 13. 04 and the driven roller 505 rotate relative to each other to crush the raw materials and reduce the particle size of the ethyl acrylate raw materials. At the same time, the ethyl acrylate raw materials are screened through the filter plate 506. The continuous rotation of the eccentric wheel 11 can make the filter plate 506 vibrate continuously, thereby vibrating and screening the raw material particles on the surface of the filter plate 506, improving the screening efficiency of the filter plate 506, blocking the particles that are not conducive to the stirring and mixing of the reactor body 1, and the particles that are conducive to the stirring and mixing of the reactor body 1 pass through the filter plate 506 and are poured into the inner cavity of the reactor body 1 through the discharge pipe 502, and the raw materials and liquid inside the reactor body 1 are mixed and produced by the first motor 4.
