Automatic Tube Filling and Sealing Machine – Key Functional Features

Our automatic tube filling and sealing machine is a multi‑functional rotary packaging unit built for processing pastes, creams, ointments and high‑viscosity gels inside plastic and laminated soft tubes. It consolidates tube feeding, volumetric filling, hot‑air sealing and batch date coding within one compact unit. Built‑in safety interlocks and well‑known brand core components guarantee stable round‑the‑clock production for cosmetic, personal‑care, pharmaceutical and health‑care manufacturing sites. Operators can quickly switch between different tube diameters for flexible batch production.

Core Machine Features & Innovative Design

1. Spring‑loaded Tube Pucks for Consistent Seal‑Tail Height

Spring‑supported tube pucks hold tubes securely in position throughout sealing cycles. This mechanical design keeps sealed tail heights uniform across the whole production batch, improving finished‑product visual consistency.

2. Automatic Colour‑mark Registration for Special‑Shape Tubes

The integrated colour‑mark tracking system enables accurate automatic superscript alignment for oval tubes and other non‑standard special‑shaped tubes, ensuring graphics and text are correctly positioned after sealing.

3. Mechanically‑Driven Filling System for Stable Dosing Performance

Adopting mechanical transmission for the filling assembly, this design delivers steady material loading performance and reduces volumetric deviation for viscous paste‑type raw materials.

4. Lifting‑Puck Filling Station

The filling station applies rising‑puck movement. Tubes lift toward the filling nozzle during dosing, minimising foam generation and material splashing inside soft tubes.

5. Original LEISTER Hot‑air Heater Unit

Fitted with original LEISTER hot‑air heater as the core heating source, offering stable heat output and long service life for continuous tube‑sealing workflows.

6. Inner Hot‑air Sealing with Circulating Water Tube‑wall Cooling

Hot air heats and melts tube inner layers for reliable sealing, meanwhile circulating cold‑water cools tube outer walls. This dual‑temperature treatment delivers durable, wrinkle‑free sealing quality and prevents tube‑wall over‑deformation.

7. Taiwan‑manufactured Exhaust Fan for Hazardous‑gas Ventilation

A high‑quality Taiwan‑made exhaust fan extracts hot fumes and harmful volatile gases out of the workshop environment, improving on‑site working conditions for operators.

8. Post‑sealing Air‑cooling System to Avoid Heat Transfer to Contents

After sealing is completed, built‑in air cooling rapidly dissipates residual sealing heat. It stops excessive heat from conducting into paste or cream products and protects heat‑sensitive formulations.

9. PLC‑based Full‑automatic Control Architecture

All major production cycles are managed by a programmable logic controller, for centralised process logic, fault judgment and parameter storage.

10. High‑definition Visual Stainless‑steel Machine Frame

The machine frame is constructed with sanitary stainless‑steel, with transparent protective guards. Operators can directly observe running status while meeting basic hygiene requirements for cosmetic and pharma production.

11. Easy Connection with External Emulsifier Mixers

Simple mechanical‑pipeline interfaces allow straightforward linking between this tube filler and upstream emulsifier mixing equipment, streamlining your whole production workflow.

12. Fast Change‑over for Multiple Tube Diameters

Tooling adjustments are simplified. Manufacturers can switch among tubes of different inner diameters without complex re‑calibration, supporting multi‑SKU small‑batch‑to‑medium‑batch manufacturing.

13. All‑in‑one Processing: Filling, Sealing and Batch Coding

One single machine finishes tube filling, tail sealing and date / batch code printing. It saves factory floor space and cuts handling steps between separate stations.

14. Full‑auto Tube Handling Workflow

Complete automatic functions cover tube feeding, tube rejection, colour‑mark searching, material filling and tube sealing, lowering manual intervention requirements.

15. Stepless Frequency Speed Regulation & High‑capacity Tube Magazine

Production speed supports stepless frequency conversion adjustment. Combined with console‑type high‑capacity tube storage bin, the main unit can realise automated bulk tube feeding.

16. Adjustable Production Batch Counter

Built‑in counting function lets operators set target output quantity; the machine keeps real‑time statistics of finished tubes for production record‑keeping.

17. Robotic Code‑printing Mechanism for Precise‑position Marking

Mechanical code‑printing robot automatically stamps batch codes exactly on pre‑defined tube positions for traceability of finished goods.

18. HMI Touch‑screen for Direct Data Display & Parameter Control

Operational data, running status and fault prompts are visualised on the human‑machine interface touch panel. Operators adjust recipes directly on‑screen.

19. Console‑style High‑capacity Tube‑storage Magazine

Large‑volume tube‑holding magazine reduces the frequency of manual tube refilling during long production runs.

20. Original Vacuum Generator for Tube‑adsorption Positioning

Original‑equipped vacuum generator drives tube adsorption and positioning devices, ensuring accurate tube pick‑up before filling cycles.

21. Omron Photo‑electric Tube Upside‑down Detection & Cam‑indexing Rotary Table

Omron photo‑electric sensors precisely identify upside‑down mis‑oriented tubes. Cam‑indexing rotary turret delivers stable station‑to‑station transfer for every processing step.

22. Automatic Cleaning & Dust‑collection Recycling System

Integrated self‑cleaning and dust‑residue recycling setup collects splashed paste and dust particles, keeping internal chambers cleaner and lowering cross‑contamination risks.

23. Multi‑layer Safety Protection Mechanisms

Equipped with malfunction alarm prompts, safety interlock for machine‑gate opening, and overload‑triggered emergency stop device to safeguard operators and mechanical assemblies.

24. Air‑blow Tail Trimming for High‑viscosity Products

Once filling finishes, an air‑blow blower trims residual material from tube tails. This feature is optimised for processing extremely high‑viscosity pastes and gels.

25. Column‑type Thermal‑insulation Agitation System (Optional Accessory)

Optional insulated stirring tank keeps raw materials at stable temperature, preventing thick paste from solidifying inside the feeding hopper.

26. BANNER Ultrasonic Material‑level Detection System (Optional Accessory)

Matched with BANNER ultrasonic level sensor and Siemens signal module, this optional system accurately monitors material stock level, and displays real‑time level readings on the touch‑screen HMI.

27. No‑Tube No‑Fill Protection Logic

When no tube is detected in position, the system skips the filling action automatically, avoiding waste of paste material.

Typical Industrial Applications

• Cosmetics: facial cleanser, hand cream, body lotion, hair‑care paste
• Pharmaceutical: topical ointments, medicinal gel tubes
• Personal‑care products: toothpaste and hygiene pastes
• Health‑care & specialty high‑viscosity formula processing
