AI Technical Summary
Traditional cam-linkage driven filling and sealing equipment is prone to wear and tear and generates high noise, leading to unstable product quality.
The heat-sealing tail cutter mechanism adopts a fully servo-driven system, which uses a transmission system consisting of a servo motor, lead screw and guide rail to replace the traditional mechanical drive. Combined with a servo electric cylinder and linkage rod, it achieves precise control of the cutting action, reducing noise and wear.
It achieves reduced noise, precise movement, reduced wear, replaceable cutter, convenient modular maintenance, and improved product quality stability.
