Extrusion granulation device for flame-retardant plastic particles

The utility model relates to the technical field of granulators, in particular to a flame-retardant plastic particle extruding and granulating device. According to the technical scheme, the device comprises an outer box, a feeding pipe is installed on the side wall of the upper portion of the outer box, an opening groove is formed in the side wall of the bottom of the outer box, a cutting plate is fixedly connected to the middle position in the outer box, and an extrusion plate is slidably connected to the position, located above the cutting plate, in the outer box through a synchronous hydraulic cylinder; a collecting box is arranged in the outer box and corresponds to the opening groove in position, and an anti-sticking mechanism is arranged in the outer box and located between the cutting plate and the screening cover. By means of the arc-shaped grids on the screening cover, cut-off flame-retardant plastic particles can be screened, small particles are removed, in the process, the particles which are just
