Automatic Linear Tube Filling and Sealing Machine

Application & Process

An automatic linear tube filling machine is a sophisticated piece of equipment used in various industries to efficiently fill and seal tubes with products like creams, gels, pastes, ointments, adhesives, and other viscous or semi-viscous substances. The automatic nature of this machine allows for high-speed production and is suitable for medium to large-scale manufacturing operations. Industries that commonly utilize automatic linear tube filling machines include pharmaceuticals, cosmetics, food, chemical, and personal care industries.

Process: The process of using an automatic linear tube filling machine involves several sequential steps to ensure accurate and efficient tube filling and sealing. The exact process can vary based on the specific model and features of the machine, but the general steps are as follows:

1. Tube Loading and Orientation: Empty tubes are loaded into the machine’s tube holders or magazine automatically. The machine may include an orientation system that positions the tubes correctly, ensuring that the tube’s opening is aligned for filling and sealing.
2. Product Feeding and Filling: The product to be filled is placed in a large reservoir or hopper connected to the machine. The automatic linear tube filling machine is equipped with a highly precise filling system, such as a piston-based filling or a peristaltic pump. The machine dispenses the predetermined volume of product into each tube accurately and consistently.
3. Product Leveling and Trimming (Optional): Some machines may have features to level the product surface in each tube to achieve a uniform appearance. Additionally, an automatic tube trimming mechanism may be included to remove excess product before sealing.
4. Tube Sealing: After filling, the tubes move along the conveyor to the sealing station. The automatic linear tube filling machine utilizes a sealing mechanism, which can vary based on the machine’s design and the type of tube being used. Common sealing methods include heat sealing, ultrasonic sealing, or crimping.
5. Coding and Marking (Optional): For products that require batch numbers, expiration dates, or other information, the machine may have an integrated coding or marking system to print this information on the tubes automatically.
6. Tube Ejection: Once the tubes are filled, sealed, and coded (if applicable), they are automatically ejected from the machine, ready for further packaging and distribution.
7. Cleaning and Maintenance: Regular cleaning and maintenance are essential to keep the automatic linear tube filling machine in optimal working condition. Depending on the machine’s complexity, some maintenance tasks may be automated or require manual intervention by maintenance personnel.
8. Changeover and Adjustments: Automatic linear tube filling machines are designed to handle different tube sizes and products efficiently. When switching to a different product or tube size, operators may need to perform a changeover and adjust the machine’s settings accordingly.
