Multi-lane liquid packaging machines are fully automatic dispensing and sealing devices for liquid or semi-fluid products (such as soy sauce, honey, juice, medicine, shampoo, etc.).
With the increasing demand for small-packaged and portable products in the consumer goods industry, the market for multi-lane liquid packaging machines is experiencing rapid growth. Its application scope has expanded from traditional condiments and beverages to functional beverages, jellies, sauces, medicines, and many other fields.
Main components
A standard multi-lane liquid stick pack machine mainly consists of the following parts:
1. Film feeding and separating system: Automatically separates the film roll into multiple columns while maintaining constant tension. A photoelectric tracking system identifies positioning markers to ensure accurate pattern and sealing positions.
2. Forming system: A forming device rolls the flat film into small bags for packaging, preparing them for subsequent filling.
3. Metering and filling system: Selects piston pumps or peristaltic pumps based on material characteristics to achieve independent metering for each column, with filling accuracy typically controlled within ±1%.
4. Heat sealing and cutting system: Uses longitudinal and transverse sealing heating devices to complete the sealing. A servo-driven cutter automatically cuts the bag into individual finished bags according to a set length.
5. Control system: A PLC and touchscreen centrally control the entire machine, providing functions such as material remaining status monitoring, alarm prompts, and production statistics.
The workflow is as follows: film placement and feeding → film separation and positioning → forming → quantitative filling → sealing → cutting → finished product output. The entire process is completed automatically and continuously, with high speed and low error.
Industry development trends
As the consumer goods market shifts towards smaller, more portable, and more refined packaging, the application of multi-lane liquid stick pack machine continues to expand in the packaging industry. Future development will primarily exhibit the following trends:
1. High Speed and Multi-Layer Configuration: The equipment is being upgraded from the traditional 4-6 rows to 8-12 rows, employing a servo independent drive system to achieve higher speeds and more stable filling accuracy.
2. Intelligent Control: Functions such as automatic deviation correction, missing bag detection, sealing monitoring, and data recording make the production process more intelligent and reduce labor costs.
3. Hygienic and Clean Design: In the food and pharmaceutical industries, the equipment widely uses 316L stainless steel, which is easy to clean and meets hygienic production requirements.
