Product Details：
Product Overview
KR‑1209 light‑duty tunnel‑style metal detector is an inline contamination‑inspection unit for light‑weight packaged goods. Built on 304 stainless‑steel framework, it identifies ferrous, non‑ferrous and stainless‑steel foreign fragments embedded inside products. When metal contaminants are detected, it triggers sound‑light warning and optional automatic rejection action.
This unit complies with HACCP, GMP and CAS hygiene requirements. It fits food processing lines, textile & garment factories, toy‑manufacturing workshops and light‑goods production workflows, for screening broken needles, iron shavings and various metallic impurities. Max acceptable single‑item load reaches 5 kg, and multiple tunnel dimension variants are available for custom‑fit production‑line integration.
Core Product Competitive Advantages
- Intuitive 7‑inch touch‑screen human‑machine interface
High‑definition color touch panel supports Chinese‑English bilingual switching. Operators can view real‑time detection signal strength, total pass count and defective‑product statistics on main screen. Menu logic is streamlined to lower operator training requirements.
- One‑touch auto‑learn parameter calibration
The one‑click self‑learning function automatically optimizes detection thresholds after sample passes through the tunnel once. Manual fine‑tuning is largely eliminated, which greatly simplifies recipe setup for frequent product‑change‑over scenarios. It can store parameters for up to 200 different product recipes for quick recall.
- Traceable operation & detection log storage
Built‑in data‑logging module keeps user‑access history and inspection records. Operators can review production statistics including total throughput, qualified and rejected‑item counts, supporting quality trace‑ability for factory audit requirements.
- Strong anti‑interference sensor module
Specially‑optimized detecting coil hardware suppresses on‑site electromagnetic noise from surrounding workshop equipment, delivering stable sensitivity for long‑hour continuous‑run production. Service lifespan of key sensing components can achieve over 10‑year under regular maintenance.
- Modular hygienic mechanical construction
Whole‑machine adopts 304 food‑grade stainless‑steel. Food‑safe PU white conveyor belt is easy to wipe and sanitize. Universal casters plus adjustable levelling feet allow quick re‑positioning. Multiple reject mechanisms (push‑rod, flap‑drop, air‑blast) are optional for integration into existing assembly‑lines. Auto‑diagnosis function alerts operators for hardware fault conditions.

Standard Complete Test Operating Workflow
- Pre‑Test Preparation
Lock machine casters and adjust levelling feet for horizontal stability. Confirm power supply is correctly connected. Power‑on the unit and finish system self‑diagnosis. Select or run auto‑learn calibration for the current production product. Verify alarm function with standard metal test‑cards.
- On‑Line Continuous Inspection
Feed finished‑goods evenly onto the inlet‑side of conveyor belt. Products travel through detection tunnel. Sensor continuously scans for embedded metallic foreign particles.
- Contaminated‑Product Handling
Once metal impurity is identified, machine activates sound‑light alert. If auto‑reject assembly is fitted, defective unit will be diverted out of main product stream. Operators segregate flagged goods for root‑cause analysis. Qualified articles keep moving along conveyor to next‑stage process.
- Production‑Data Review
At shift‑change or batch‑completion, pull‑up statistical log from touch‑screen: total pieces, reject‑count and timestamps for quality‑report archiving. Call‑up stored product‑recipe when switching to new item model.
- Post‑Shift Maintenance
Cut off product feeding. Clean conveyor surface and tunnel interior to remove debris and residues. Power‑off main power if long‑time shutdown is required. Periodically validate sensitivity with standard metal test samples.
