The utility model discloses an
impurity removal device for composite
fiber processing, which comprises a shell, a
discharge pipe is arranged at the bottom of the shell, an unloading
assembly is arranged on the inner wall of the
discharge pipe, the unloading
assembly comprises a first threaded cylinder, a first driving
bevel gear and a second driving
bevel gear, a second threaded cylinder is rotatably mounted at the bottom end of the first threaded cylinder, a first
threaded rod is mounted on the inner wall of the first threaded cylinder in a threaded mode, a filter screen is rotatably mounted at one end of the first
threaded rod, and a first transmission
bevel gear is fixedly mounted on the outer wall of the first threaded cylinder; a second
threaded rod is installed on the inner wall of the second threaded cylinder in a threaded mode, a sealing plate is rotatably installed at one end of the second threaded rod, and a second transmission bevel gear is fixedly installed on the outer wall of the second threaded cylinder.
