Full-Automatic Rollstock Thermoforming Filling & Sealing Machine

Dual-Film Compatible + Double-Side Labeling & Coding Integrated Solution

I. Technical Foundation Clarification

This machine belongs to the rollstock thermoforming fill-seal category (Form-Fill-Seal machine for rollstock film), widely used for small-volume plastic ampoule production.

II. Core Challenge 1: How to achieve "double-side labeling + coding" simultaneously with forming, filling, and sealing?

2.1 Challenge Analysis

• Symmetric dual-label head layout: Modular symmetrical labeling units (based on continuous single/double-side labeling technology) are installed on both left and right sides after the forming station and before filling/sealing. The labeling heads feature blade-type dividers to ensure label peeling without tearing. Combined with a pre-loaded conveyor chain and side guide plates, bottle displacement is minimized, achieving labeling accuracy of ±1mm.

• Integrated coding: A dual-head coding module (laser or CIJ – continuous inkjet) is integrated downstream of the labeling station. A position sensor synchronizes with the labeling action to accurately print production dates, batch numbers, and traceability information. Coding speed is matched to the film transport speed for "print-on-the-fly" operation, avoiding delays or blurring.

• Positioning & inspection: A servo-driven positioning device (including primary/secondary positioning plates and a product sensor) precisely guides the formed ampoule strips. Label alignment is verified in real-time, with a pass rate ≥98%.

2.2 Technical Solution: Inline Integrated Double-Side Labeling & Coding Module

We embed the labeling and coding processes directly into the machine’s rear section, completing all marking operations after sealing but before cutting and output.

• No additional cycle time: Labeling and coding run at the same speed as forming, filling, and sealing, without affecting output.

• Adapts to flat bottle surfaces: A flexible pressing device (top belt + guide rollers) ensures label adhesion without bubbles or detachment.

Process Flow:
Film Unwind → Heating → Thermoforming → Filling → Sealing → Double-Side Labeling → Online Coding → Die Cutting/Separation → [Optional Vision Inspection & Rejection] → Finished Product Collection

Key Design Features:

✅ Result: Achieves "coding + double-side labeling before the cutting station" with no manual intervention or post-process cost.

III. Core Challenge 2: How to make one machine compatible with both single-web and dual-web film?

3.1 Definition of the Two Web Modes

Using a "modular film delivery + closed-loop tension control" architecture, the machine allows tool-less fast switching between single-web (single-layer body) and dual-web (multi-layer/barrier layer body) modes via mechanism changeover and parameter adjustment.

3.2 Technical Solution: Modular Unwind + Switchable Folding Mechanism

• Core concept: The unwind section features a dual-station film carriage with a quick-mount/dismount folding guide, allowing one-touch switching between modes.

System Configuration:

• Dual-web mode: Upper web → guide rollers → forming station / Lower web → guide rollers ↗

• Single-web mode: Single web → folding mechanism → folded dual-layer web → forming station

Key Design Points:

• Dual-mode film delivery system: A switchable web delivery system with two mounting brackets and horizontal adjustment modules (linear guides + sliding bases). In single-web mode, one path is active. In dual-web mode, both paths feed simultaneously, with alignment calibrated via the horizontal adjustment mechanism.

• Closed-loop tension control: Integrated tension regulators (drive cylinders + linear sensors) monitor tension in real-time. In dual-web mode, each web’s tension is controlled independently (accuracy ±0.1N) to prevent slack or over-tension. In single-web mode, one tension control loop is automatically disabled.

• Compatible forming dies: Custom integrated dies accommodate single or dual-web thickness (single-layer 0.1-0.5mm, dual-layer 0.2-1.0mm) via cavity parameter adjustment – no die change required.

Changeover Procedure (≤ 20 minutes):

✅ Result: One machine, two production modes – no need to purchase two separate machines, significantly reducing capital investment and floor space.
