Weigh Every Pack, Push Out the Off-Spec

Dynamic weight inspection in motion — the CQ-XP400 weighs each pack at full line speed and its pneumatic pusher automatically rejects every underfilled or overfilled product. A solid weighing frame and 400 mm-wide food-grade belt handle light and heavy packs, from snacks and pouches to 15 kg bags.

Inline Architecture

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.

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

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

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

7" Touchscreen & 100 Recipes

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

Self-Learning

15 kg Large-Volume Weighing

Up to 15 kg per pack on a 400 mm-wide belt — light and heavy products switch freely on one machine without re-configuration.

Up to 15 kg

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-XP400 can be built with any of them. The pusher configuration shown here is manufactured to order for your product and line requirements.
