[0024] As a technical optimization solution of the present invention, through the setting of the servo motor 12, the rotating disk 13, the transmission rod 14 and the connecting bar 15, the sliding frame 9 can be made to move back and forth, thereby shaking the material in the filter screen 11, thereby improving the filtering rate of the material.

[0028] As a technical optimization solution of the present invention, the six stirring bars 19 are provided to stir the material in the feed hopper 1 so that the material can be in motion, thereby avoiding accumulation of the material and making it impossible to discharge the material.

At this time, the servo motor 12 can be started to drive the rotating disk 13 to rotate. At this time, since the slide frame 9 can only perform linear motion in the slide mouth 8, the transmission rod 14 can drive the connecting bar 15 to perform linear motion, so that the filter screen 11 can be reciprocated, so that the material in the filter screen 11 can be vibrated, thereby improving the filtration rate of the filter screen 11, and at the same time, through the cooperation of the buffer 17 and the spring 18, both The spring 18 can use elastic deformation to absorb the impact force of the slide frame 9, and then the buffer 17 can be used to convert the elastic deformation of the spring 18 into mechanical energy, so as to buffer the reciprocating motion of the slide frame 9. Then the filtered material enters the feed hopper 1 through the feed channel 7. At this time, the reduction motor 4 can be started to drive the rotating shaft 5 to rotate, so that the stirring bar 19 stirs the material in the feed hopper 1, so that the material can be in a moving state, thereby avoiding the accumulation of material and making it unable to be discharged, and the spiral blade 6 can be used to make the material be sent to the feeding end of the injection molding machine through the discharge channel 3. At this time, the feeding speed of the spiral blade 6 can be adjusted by controlling the output power of the reduction motor 4.
