Automatic Linear Ultrasonic Tube Filling and Sealing Machine
This automatic linear ultrasonic tube filling and sealing machine is an innovative packaging solution engineered for high-efficiency and precision processing of plastic and laminated tubes. Distinguished from traditional rotary-type machines, its linear structural design redefines space utilization and operational convenience, integrating a full range of automatic functions to streamline the tube packaging workflow for diverse products. It is ideal for small and medium-sized production batches, laboratory trials, and regular production lines across multiple industries, delivering stable performance and high-quality packaging results.
Core Structural Advantage: Linear Layout vs Rotary Design
The machine adopts a linear layout that stands out against rotary tube filling and sealing equipment with remarkable structural merits. Its compact design significantly reduces the floor space required, making it a perfect fit for workshops with limited area or production lines that need flexible layout adjustment. Unlike rotary machines with complex rotating components, the linear structure features a clear and straightforward mechanical flow, which not only simplifies daily operation for operators but also greatly lowers the difficulty of maintenance and part replacement. All functional modules are arranged in a linear sequence, allowing for quick troubleshooting and routine upkeep, effectively reducing production downtime and improving overall operational efficiency.
Full-Automatic Operational Workflow
Realizing a one-stop automatic tube processing solution, the machine eliminates the need for extensive manual intervention in the core production process, ensuring consistent processing quality and stable output. The complete automatic workflow includes:
Automatic tube feeding: Precisely transports empty tubes to the processing station with high positioning accuracy, laying a solid foundation for subsequent procedures.
Automatic alignment: Intelligently aligns tube labels and structural marks to ensure standardized and aesthetically pleasing finished products, meeting the high requirements of brand packaging.
Automatic filling: Equipped with a high-precision dosing system that delivers accurate filling volume for each tube, avoiding material waste and ensuring product dosage consistency.
Automatic ultrasonic sealing: Adopts advanced ultrasonic sealing technology to create a tight, airtight seal on tube ends. The ultrasonic process ensures fast and reliable sealing without damaging tube materials, effectively extending the shelf life of packaged products by preventing leakage and oxidation.
Code stamping: Integrates an integrated code stamping function to print production dates, batch numbers, shelf life and other critical information on tube surfaces with clear and durable marking, complying with product traceability and regulatory requirements.
Automatic tail cutting: Precisely cuts off excess material at the sealed tube ends, ensuring neat and uniform tube tail shapes for a refined finished product appearance.
Automatic tube ejection: Automatically conveys the fully processed and finished tubes to the collection area, completing the entire packaging cycle and facilitating subsequent sorting and packaging.

Premium Material & Precision Performance
High-Quality Construction
The main body of the machine is constructed from high-grade food and pharmaceutical-grade AISI 304 stainless steel, featuring corrosion resistance, rust proofing and easy cleaning. All parts that come into contact with products are made of ultra-high-purity AISI 316 stainless steel materials, which meet strict hygiene standards and prevent any contamination to the filled products, making the machine suitable for the packaging requirements of high-hygiene industries. The smooth surface design of all components further reduces the risk of material residue and bacterial growth, simplifying the cleaning and sterilization process.
Unmatched Filling & Sealing Precision
High-precision filling: The filling system is calibrated to achieve an extremely low filling error rate, ensuring accurate dosage even for micro-volume filling requirements starting at 0.4 ml. It can adapt to the filling of different volume specifications, with a wide adjustable range to meet the packaging needs of various product types.
Reliable ultrasonic sealing: The electronic control system precisely regulates ultrasonic sealing parameters such as frequency, pressure and working time, ensuring consistent sealing quality for each tube. The sealed tube ends have strong structural strength, passing strict sealing performance tests to prevent product leakage and deterioration during storage and transportation.
Intuitive & Intelligent Control
The machine is equipped with a professional PLC control system and a human-machine interactive touch screen, which enables intuitive operation and real-time monitoring of the production process. Operators can easily set and adjust parameters such as filling volume, sealing intensity, code content and production speed on the touch screen, with the system storing multiple sets of process parameters for quick switching between different product production tasks. It is also fitted with a production output counter, which accurately records the number of finished products, facilitating production management and statistical work. In addition, intelligent sensors are installed at key stations to detect abnormal conditions in real time and issue automatic alarms, effectively avoiding defective products and equipment damage.
