AI Technical Summary
Existing blow molding barrel edge trimming devices generate plastic debris during the cutting process, which easily leads to equipment contamination and low production efficiency, and additional cooling time is required after cutting.
Design a waste edge removal device for blow-molded barrel openings. The waste edge is removed by a cutting blade on a rotating column, while the debris is adsorbed by an air suction pipe and cooled by compressed air. This achieves integrated cutting, cleaning and cooling.
It effectively prevents debris from scattering, reduces manual cleaning costs, improves production efficiency, and accelerates barrel shaping through synchronous cooling.
