[0021] When the crushing work is in progress, the crushed nucleating agent will first fall onto the screen 7, and the started motor 10 drives the cam 9 connected thereto to rotate through the output shaft, and drives the vibrating screen to reciprocate in the sliding groove under the action of the connecting rod 8, so as to screen the nucleating agent above the screen 7, and those that meet the requirements for crushing will fall into the discharge area 3. Since the screen 7 is inclined, the nucleating agent that does not meet the requirements will fall into the feed port of the spiral elevator 4 through the notch 6 and be transported to the top of the feed area 2 for re-crushing until it meets the standards. By designing the vibrating screen, the nucleating agent with larger particles can be screened and re-crushed, thereby improving the production quality, and no manual rework is required, which greatly improves the efficiency.

[0023] After long-term use, when the screen 7 needs to be maintained, first disconnect the cam 9 from the output shaft of the motor 10, then turn the handle to drive the screw 16 to rotate in place, and under the action of the thread, push the motor 10 on the top of the mounting seat 11 to move to one side until the motor 10 leaves one side of the frame 5, then take out the frame 5 along the sliding groove, and maintain the screen 7; by designing the motor 10 to be movable, it is convenient to carry out later maintenance of the screen 7, and prevent the screen 7 from being blocked or damaged, which affects the production efficiency and quality.
