Weigh Up to 40 kg, Push Out the Off-Spec

Dynamic weight inspection for heavy packs — the CQ-XP500 weighs bags, boxes and containers up to 40 kg at full line speed on a 500 mm-wide belt. Its pneumatic pusher automatically rejects every underfilled or overfilled product, while the 900 mm weighing section keeps large footprints perfectly stable.

Three-Stage Structure, Zero Interference

Products accelerate onto an isolated weighing platform and are measured in full motion — every stage physically separated so vibration and belt pull never distort the reading, even under 40 kg loads.

Core Engineering

More Than Weighing — A Smart Assistant

Every component selected for one purpose: stable, repeatable readings at production speed, with changeovers measured in minutes.

Three-Stage Isolation

Speed-up, weighing and rejection stages are mechanically separated — belt pull and vibration from adjacent sections never reach the scale platform.

Stable Reading

10" Touchscreen & 100 Recipes

Icon-driven interface with self-learning setup — store 100 product parameters, switch products in minutes without re-engineering.

Self-Learning

Digital Sensor & Zero Tracking

High-precision digital load cell with fast sampling and automatic zero tracking — long-running stability without frequent manual calibration.

1 g Resolution

40 kg Large-Range Weighing

Up to 40 kg per pack on a 900 × 500 mm belt — bags, boxes and bulky products switch freely on one machine without re-configuration.

Up to 40 kg

Food-Grade PVC Belt

Food-contact PVC conveyor keeps every pack stable during weighing — hygienic, easy to clean and suitable for all product types.

Food-Safe

USB / RS232 / RS485 & Excel Reports

Built-in statistics with EXCEL-format reports, USB storage for 1+ years of data — full traceability for audits and process control.

Data Traceability
Rejection Systems

Matched Rejection, Zero Leakage

A complete range of proven rejection mechanisms engineered for different product types — the CQ-XP500 can be built with any of them. The pusher configuration shown here is manufactured to order for your product and line requirements.
