[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By providing an annular connecting seat and a heat conducting plate at the docking end of the fixed disc and the moving disc, and installing a heating tube in the cavity, the fixed needle disc can be effectively heated, preventing materials from adhering to the blades due to moisture, achieving the effect of drying and dehumidifying the moisture of the materials, and improving the operating speed of the blades and the screening and discharging effect of the bottom screen.

[0016] 2. The heating function can reduce the adhesion of wet material dust on the blades and internal components of the machine, avoid the formation of wet oxide films, thereby reducing the corrosion and wear of the equipment and extending the service life of the equipment.

[0017] 3.
