4-Lane Back-Seal Paste Stick Pack Machine
Share to:
This is a 4-lane synchronized back-seal liquid packaging machine, through the stainless steel body and automated control system, to achieve precise liquid filling, back side sealing, automatic cutting all-in-one production.
Machine Overview and Functional Description
This packaging machine is made of food-grade stainless steel body with a solid frame and universal wheels at the bottom. The core module consists of a filling system with four independent filling channels, a back side sealing mechanism, a right side electronic control box, and a forming and cutting module. Packaging film into the equipment folded into 4 independent chambers, 4 groups of channels synchronous metering liquid injection; top heat sealing module to seal the back side, while the transverse cutter cut off, separated into individual bags; finished product through the bottom conveyor belt to collect, the whole process of automation without human intervention. 4 parallel production, compared with single / dual-column models to significantly increase production; metering error ≤ ± 1%, back sealing process to reduce packaging material loss; covering the food, chemical and pharmaceutical industries, bag size can be adjusted by the single / dual-column model, the measurement error ≤ ± 1%, back sealing process to reduce packaging material loss; covering the food, chemical and pharmaceutical industries, bag size can be adjusted by the daily, Covering food, daily chemical and pharmaceutical industries, the bag size can be adjusted through the electronic control system; automatic fault alarm + parameter memory, lowering the threshold of operation and reducing downtime.

Structural Design and Working Principle
Overall diagram
4-lane back seal liquid packaging machine is a kind of efficient packaging tool. It can automatically complete the bag making, measuring, filling, sealing and cutting process.
Longitudinal sealing device
Longitudinal sealing device, controlled by an A-bus type temperature module, provides accurate temperature control, seals the back of the packaged product, and ensures a tight seal.
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.
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
1.What are the limitations on the types of materials that can be packaged by the equipment?
The equipment is suitable for liquids with good fluidity (e.g., water-based solutions), low to medium viscosity pastes (e.g., honey, emulsions), but materials containing large particles, high solid content or strong corrosive materials (e.g., strong acids and alkalis) need to be evaluated in advance to avoid damage to the equipment.
2.Can the packing specification be adjusted flexibly?
Through the electronic control system to modify the bag length, filling volume and other parameters, to adapt to different capacities (such as 5 – 500ml) and bag size; if you need a special structure (such as shaped bags), can be customized molds or modules to support the rapid switching of multiple specifications.
3.What do I need to pay attention to for daily maintenance?
The core focus on cleaning and wearing parts: stainless steel body is easy to rinse, filling head, heat sealing knife need to be cleaned regularly to prevent rust; transmission parts are replaced according to the cycle; electronic control system comes with self-testing, can be early warning of abnormalities.
4.Does it support personalized function expansion?
It supports modular expansion, such as integrated coding, weight detection, vacuum suction; it can also be docked to the production line to meet the needs of customized production.
5.How to ensure long-term operational stability?
