So that the hob 22 can cut a plurality of strands better. At the grain cutting in-process of hobbing cutter 22, upper cover 23 lid closes the top of cutting chamber 101, compresses tightly frame 4 and balancing weight 431 this moment and compresses tightly towards the direction of cutting chamber 101 feed inlet for nip roll 21 can contradict in the material strip, takes place the phenomenon that the material strip skidded at the grain cutting in-process in order to prevent. Hob 22 obtains plastic granules after cutting the material strip into particles, plastic granules from the discharge gate department of blank room 101 through discharging pipe 6 and connecting pipe 61 and finally fall into receiving box 7, when the plastic granules in receiving box 7 reached a certain amount, the staff can make the discharge gate that the solenoid valve closed discharging pipe 6, then make connecting ring 611 of connecting pipe 61 break away from annular groove 711, shift out the space that two limiting plates 102 formed with this receiving box 7 at last, shift receiving box 7 that will not be equipped with plastic granules into the space between two limiting plates 102 again, and continue to receive the material.

The above embodiments are merely illustrative of the present invention, and are not intended to limit the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the present invention.
