AI Technical Summary
The cutting blades of existing PP granulation machines are prone to accumulating plastic residues, which leads to decreased cutting performance and poor particle uniformity.
A PP granulator including a cleaning mechanism was designed. The first and second cleaning units automatically clean the plastic residue on the surface of the cutting blade, and the guide rod is driven by a servo motor and a bevel gear meshing transmission system to discharge the uncut plastic and prevent accumulation.
It effectively extends the working time of the cleaning mechanism, reduces the frequency of manual cleaning, improves the cutting quality of the cutting blade and the uniformity of the particles, and prevents the cutting box from clogging.
