ZONESUN ZS-MD2 Automatic Cap Detection Machine for Tilted Cap Loose Cap & Foil Liner Inspection System

Description

The ZONESUN ZS-MD2 is an automatic bottle cap detection and rejection machine designed for identifying high caps, tilted caps, loose caps, and aluminum-foil presence. Operating at up to 6800 bottles per hour, it combines contact-based separation detection with metal-foil sensing to ensure accurate quality judgment. Qualified bottles pass through automatically, while defective bottles are diverted into a side buffer for manual handling. This prevents defective products from entering finished goods, reducing customer complaints, market returns, and hidden losses. With its stable structure, high compatibility, and efficient rejection mechanism, it is ideal for integration into medium to large-scale production lines.

CONTROL PANEL
Controls the feeding speed, cap-height inspection, and rejection of bottles with high or insufficiently tightened caps.

SPONGE DUAL SORTING DEVICE
Stabilizes bottles and creates even spacing before they enter the inspection area, supporting accurate tilted-cap detection.

BOTTLE CAP INSPECTION STRUCTURE
Detects tilted, high, loose, or improperly sealed caps through precise sensing to determine whether each bottle meets quality requirements.

PNEUMATIC LANE-SWITCHING ROTARY DEVICE
Diverts defective bottles by rotating a pneumatic arm and directing them into a separate rejection lane for controlled removal.

LANE ISOLATION PLATE
Separates the normal bottle path from the rejection lane, ensuring smooth flow and preventing defective bottles from re-entering the main line.
