It delivers ±0.1g–±0.2g accuracy at up to 100 pcs\/min with a SUS304 stainless steel frame and 7-inch color LCD touch screen control. Ideal for pharmaceutical, food, toy, hardware, and chemical manufacturing lines seeking to replace manual weighing and improve output consistency.\u003c\/p\u003e\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe JZ-150 is a conveyor-based online checkweigher designed to perform automatic weight detection, overweight and underweight discrimination, and multi-grade weight sorting directly on the production line. Built with a single-chip microcomputer system and a proprietary filtering algorithm, the machine maintains stable detection performance even in demanding industrial environments.\u003c\/p\u003e\n\u003cp\u003eThe 7-inch large-format color LCD touch screen provides an intuitive operator interface with password-protected parameter settings, ensuring that only authorized personnel can modify inspection criteria. The system supports storage of up to 100 product test profiles, enabling fast changeovers across multiple SKUs without reconfiguration delays.\u003c\/p\u003e\n\u003cp\u003eAn automatic zero-point tracking system continuously compensates for environmental drift, maintaining reliable data output throughout extended production runs. The photoelectric empty-bag detection function and adjustable conveyor belt speed allow the machine to adapt to varying product flow rates. The buckle-type conveyor belt design simplifies disassembly for cleaning and routine maintenance, supporting food-grade and pharmaceutical hygiene requirements.\u003c\/p\u003e\n\u003cp\u003eKeypack Intelligent (kunbupack) JZ-150 Checkweigher supports multi-language operation (default: Chinese and English; additional languages available upon request) and offers an optional three-light alarm system for real-time out-of-tolerance alerts.\u003c\/p\u003e\n\u003ch2\u003eKey Features and Machine Characteristics\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Accuracy Weight Detection:\u003c\/strong\u003e ±0.1g–±0.2g mini scale accuracy supports precise overweight and underweight discrimination, reducing product giveaway and non-conforming shipments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Speed Inspection:\u003c\/strong\u003e Rated up to 80–100 pcs\/min, the JZ-150 integrates smoothly into fast-moving automated assembly lines and logistics sorting systems without creating bottlenecks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Zero-Point Tracking:\u003c\/strong\u003e Continuously compensates for environmental and mechanical drift, maintaining consistent and reliable detection data across long production shifts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto-Learning System:\u003c\/strong\u003e Adjustable conveyor belt speed combined with an auto-learning function allows the machine to adapt to different product weights and line speeds with minimal manual intervention.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhotoelectric Empty-Package Detection:\u003c\/strong\u003e Automatically identifies and flags empty or missing-product packages before they pass through the weighing zone, reducing false rejects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100-Product Data Storage:\u003c\/strong\u003e Stores up to 100 individual product inspection profiles, enabling rapid line changeovers and supporting multi-SKU production environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePassword-Protected Parameter Settings:\u003c\/strong\u003e Access control ensures that inspection thresholds and system configurations are managed only by authorized personnel, supporting GMP and quality management requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy Maintenance Design:\u003c\/strong\u003e Buckle-type conveyor belt allows tool-free disassembly for cleaning and inspection.
