8-Lane Back-Seal Liquid Stick Pack Machine
Machine Overview and Functional Description
This8-lane Liquid Packaging Machine is a highly automated multi-column synchronized packaging equipment for liquid and semi-fluid materials. The frame is made of food-grade stainless steel, corrosion-resistant and easy to clean, in line with the hygiene standards of food and pharmaceutical industries. Equipped with 8 groups of independent filling heads, it can synchronize liquid metering and filling to improve production efficiency, and the piping design is suitable for watery and viscous materials with different fluidity. The right side of the integrated touch screen control system, support the filling volume, speed, sealing temperature and other parameters set, operation monitoring and fault warning; the front of the equipment is equipped with a transparent window, easy to observe the internal bag making, filling, sealing process and debugging. Universal casters and adjustable support feet at the bottom are convenient for equipment transportation and layout adjustment, and the support feet are locked to ensure stable operation. Packaging film folded and shaped by the molding agency for 8 independent bag cavity; 8 filling head synchronous start, through the metering pump, flowmeter to accurately control the amount of injection (error ±1% or less), suitable for 5 ~ 200ml specifications; bag body into the sealing area, the first longitudinal sealing to connect the two sides of the bag, and then transverse sealing closed the bag and cut off the separation of the 8 independent packages for continuous output.

Structural Design and Working Principle

Schematic diagram of the whole machine
The 8-lane Liquid Packaging Machine can package a wide range of materials such as shampoo, oral liquid and seasoning sauce, helping enterprises to realize efficient production.
Touch screen in 12 languages
Human-machine interface, controlled by an intelligent system to adjust the entire machine’s parameters and operation, making parameter adjustment more convenient.
Hopper device
The hopper is used for temporary storage of liquid materials, often equipped with liquid level sensors, to control the feed and prevent overflow, to ensure the continuous supply of materials.
Film supply device
The automatic film frame correction device can automatically or manually correct the film frame to ensure that the packaging film remains stable during the bag making process.
FAQs
Question 2: How to ensure the stability and consistency of the equipment during operation?
The equipment adopts food-grade stainless steel frame with stable structure; it relies on PLC control system to accurately regulate the filling and sealing processes and monitor the status in real time. The independent filling units of each column are designed in collaboration with the stable liquid supply system to ensure the consistency and stability of multi-column synchronized operation.
Question 3: When synchronized filling of multiple columns, how to ensure the uniform measurement of materials in each column?
The equipment is equipped with independent filling components for each column, relying on precise metering devices (e.g. metering pumps, flow meters) and coordinating the timing and dosage through the control system. Synchronized control algorithm and feedback mechanism, real-time correction of deviation, to ensure uniform filling volume of multiple columns.
Question 4: For materials with different viscosities, how can the equipment be adapted?
For watery, viscous and other different materials, the filling system can replace the pump body and adjust the piping design to fit. Components with easy to disassemble, easy to clean the characteristics of the material switch to facilitate the cleaning and maintenance, to avoid cross-contamination, to enhance the flexibility of production.
Question 5: What are the after-sales and technical support contents of the equipment?
Manufacturers provide installation and commissioning, operation training services; the establishment of a rapid after-sales response mechanism, timely handling of fault repair. At the same time, we supply wearing parts and provide regular maintenance guidance to help customers ensure the long-term stable operation of the equipment and reduce operation and maintenance costs.
