At the same time, an eccentric wheel 11 is arranged in the middle of the screening box body 2. A rotating shaft 12 is fixedly installed inside the eccentric wheel 11. At the same time, the eccentric wheel 11 is located inside the sieve plate 4. A first motor 13 is connected to the right side of the rotating shaft 12. Turning on the first motor 13 can make the eccentric wheel 11 and the rotating shaft 12 rotate. When the eccentric wheel 11 rotates, it will contact the sieve plate 4.

The fixed block 10 is fixedly connected to the screening box body 2. The fixed block 10 plays a stabilizing role for the sieve plate 4 and the fixed ring 3. That is, when the eccentric wheel 11 rotates, it will push the sieve plate 4 to move inside the screening box body 2, that is, the spring 9 will stretch and rebound. The sieve plate 4 can efficiently screen out the sundries in the additive material.
[0039] In the present utility model, a disassembly mechanism is provided. The disassembly mechanism is arranged inside the screening box body 2. The disassembly mechanism includes clamping grooves 5 symmetrically formed on the left and right inside the fixed ring 3. The clamping grooves 5 can be engaged with clamping blocks 6 installed on the left and right sides of the sieve plate 4. At the same time, a movable door 7 is rotatably installed on the front side of the screening box body 2. The sieve plate 4 and the fixed ring 3 are engaged and connected together. That is, by opening the movable door 7, inserting the hand into the handle groove 8 formed inside the sieve plate 4, pulling out the sieve plate 4 from above the fixed ring 3, and then moving the sieve plate 4 out of the inside of the screening box body 2 through the movable door 7, the sundries screened out inside the sieve plate 4 can be cleaned regularly.
