Online Checkweigher Parameter JZ-400

Keypack Intelligent JZ-400 Inline Checkweigher is an automatic dynamic checkweighing system engineered for precise in-line weight detection, overweight/underweight discrimination, and multi-grade weight sorting on high-speed conveyor lines. It delivers ±5–10g weighing accuracy at 30–40 pcs/min with a robust SUS304 stainless steel frame and an intelligent auto-learning control system. Ideal for pharmaceutical, food, toy, hardware, and chemical production lines requiring reliable, automated weight inspection.

Product Overview

The JZ-400 is a conveyor-based industrial checkweigher designed to replace manual weighing and integrate seamlessly into automatic assembly lines and logistics delivery systems. Operated via a large 7-inch color LCD touch screen, the system supports intuitive parameter configuration and real-time weight monitoring without specialized training.

The Keypack Intelligent (kunbupack) JZ-400 Checkweigher stores up to 100 product test profiles, enabling fast changeover between SKUs on multi-product lines. Its independently developed single-chip microcomputer system, combined with a proprietary filtering algorithm, ensures stable and consistent detection data even in demanding industrial environments. The buckle-type conveyor belt design allows easy disassembly for cleaning and maintenance, supporting hygienic production requirements.

With an adjustable conveyor belt speed, photoelectric automatic detection of empty bags, and an automatic zero-point tracking system, the JZ-400 delivers reliable data output across varying production conditions. Password-protected parameter settings ensure that only authorized management personnel can modify system configurations, maintaining process integrity.
