Fully Automatic Capping Machine

Wanying is a professional manufacturer focusing on filling and packaging automation systems for beverage, condiment, dairy, and liquid food industries. Backed by a 3000 ㎡ production base, patented technologies, and more than 1300 engineering projects, the company provides Fully Automatic Capping Machine solutions and complete turnkey production line integration for global industrial clients seeking stable and efficient automation upgrades.

Product Definition & Functional Overview

The Fully Automatic Capping Machine is an industrial packaging equipment designed to automatically apply and tighten caps onto filled bottles in high-speed production environments. It replaces manual or semi-automatic capping processes and ensures each bottle is sealed with consistent torque and alignment.

What It Does:

· Automatically feeds caps into the production system

· Sorts and orients caps for correct positioning

· Applies caps onto filled bottles in a continuous flow

· Tightens caps with controlled torque for secure sealing

· Rejects improperly capped bottles to maintain quality consistency

Core Function Positioning:

It acts as the final sealing unit in a liquid packaging production line, ensuring product safety, leakage prevention, and packaging integrity before labeling and cartoning.

Capping Principle & Closed-Loop Torque Control

The Fully Automatic Capping Machine utilizes a servo-driven capping head with real-time torque feedback. As the cap is placed onto the bottle mouth, the capping head descends and rotates at a controlled speed. A built-in torque sensor provides continuous feedback to the PLC: when the preset torque value (1–12 Nm) is reached, the servo motor instantly stops and releases the cap. This closed-loop control ensures every cap is tightened with consistent torque, eliminating human error and preventing under-tightening (leakage) or over-tightening (cap/thread damage).

Torque Selection Guide by Cap Type:

Plastic screw caps (15–30mm): 1–4 Nm

Aluminum caps (20–40mm): 3–7 Nm

Tamper-evident caps (25–50mm): 5–10 Nm

Large-diameter caps (40–60mm): 8–12 Nm

Anti-Misalignment & Rejection System

The machine is equipped with photoelectric sensors to detect:

Missing caps – no cap detected before capping station

Tilted caps – cap angle deviation beyond tolerance

Cross-threaded caps – abnormal torque profile during capping

Any abnormal condition triggers an automatic rejection mechanism, preventing defective bottles from reaching downstream labeling or packaging stages and reducing manual inspection costs.
