[0023] The raw materials are screened by the screening drum 10, and large particles are retained inside the screening drum 10, and small particles fall into the collecting drum 9. The first motor 3 is used to pull the first supporting column 4 to rotate, and the first gear 6 on the first supporting column 4 and the second gear 7 on the second supporting column 5 are meshed with each other, so that the first supporting column 4 and the second supporting column 5 can rotate at the same time and in opposite directions. After the screening drum 10 is taken away from the collecting drum 9 by the lifting assembly, the first motor 3 is activated to drive the collecting drum 9 and the screening drum 10 to flip at the same time, so that large and small particles of raw materials can be simultaneously exported, so that small particles can be used for the production of nylon PA66. The empty collecting drum 9 and the screening drum 10 can screen the next raw material.

[0024] Among them, a third supporting column 12 is rotatably connected between the front and rear inner walls of the screening drum 10 through a bearing, a plurality of stirring blades 13 are fixed to the outer wall of the third supporting column 12, and the plurality of stirring blades 13 are distributed in a circular array. A second motor 14 is arranged on the front side of the screening drum 10, and the third supporting column 12 is driven by the second motor 14.

[0025] The third support column 12 is rotated by the second motor 14 , and the third support column 12 drives the stirring blade 13 to stir the raw materials inside the screening drum 10 , so that the raw materials can be better screened with the help of the screening drum 10 .

[0026] Among them, the lifting assembly includes a rectangular frame plate 15, which is fixedly mounted on the carrier plate 8.

[0028] How this utility works:

[0029] A single raw material for producing nylon PA66 is put into the screening drum 10, and the second motor 14 is started to drive the third support column 12 and the stirring piece 13 thereon to rotate, so as to drive the raw material inside the screening drum 10 to stir, so that the raw material is screened by the screening drum 10, and large particles of the raw material are trapped inside the screening drum 10, and small particles of the raw material fall into the collecting drum 9.

The first gear 6 and the second gear 7 are meshed with each other. Therefore, the second carrier column 5 rotates while the first carrier column 4 rotates, and the two rotate in opposite directions. While the first carrier column 4 pulls the collecting drum 9 to rotate forward, the screening drum 10 is pulled by the second carrier column 5 to rotate in the opposite direction, so that the small particle raw materials in the collecting drum 9 can be discharged and supplied to the equipment for producing nylon PA66, and the large particle raw materials trapped in the screening drum 10 will be put into the crushing equipment for crushing. After all the raw materials in the collecting drum 9 and the screening drum 10 are discharged, the first motor 3 can be controlled to pull the first carrier column 4 to reverse, so that the collecting drum 9 is reset. Subsequently, the lifting assembly pulls the screening drum 10 to move down and reset. After that, the next raw material can be put into the inside of the screening drum 10 to continue screening and feeding the raw materials.
