Linear Top and Side Sealing Machine for Pouch Lithium Battery Packaging

Product Overview

This linear top and side sealing machine is designed for packaging dual-tab pouch lithium batteries after the cell has been placed inside a formed aluminum-plastic film housing. It combines fixture-based positioning, servo-driven transfer, cylinder-actuated top sealing, and side sealing in one controlled process. The result is a repeatable packaging sequence that supports consistent sealing quality while keeping the loading and unloading workflow clear for operators.

The equipment is suited to pouch-cell fabrication lines requiring top sealing and one-side sealing operations. An operator loads the formed aluminum-plastic film into the fixture, inserts the cell into the housing, and secures the fixture pressure plate. The system then moves the fixture through the configured sealing stations before returning it to the loading position for unloading. It supports either dual top sealing or a single top sealing operation, followed by side sealing.

Built around PLC automatic control, a touch-screen human-machine interface, and a stable aluminum-alloy profile frame, this unit is engineered for controlled, repeatable production work. Adjustable temperature and sealing time settings, alarm functions, fixture detection protection, and door-switch protection help maintain reliable operation under defined process conditions.

Key Features

• Linear Servo Fixture Transfer: A servo mechanism transfers the clamped fixture from loading to top-sealing and side-sealing positions in sequence. This controlled movement supports a consistent process path and returns the fixture automatically to the loading location after sealing.

• Dual or Single Top-Sealing Capability: The cylinder-actuated top-sealing mechanism can complete two top seals simultaneously or one top seal as required by the operation. This flexibility supports packaging processes for dual-tab pouch cells without changing the overall linear workflow.

• Adjustable Sealing Temperature: Sealing-head temperature is adjustable from room temperature to 260℃, with configurable compensation and a control accuracy of ±2℃. Preset temperature control enables the process to be aligned with the required aluminum-plastic film sealing condition.

• Configurable Seal Timing: Sealing time is adjustable from 0 to 99.9 seconds. Operators can preset the timing parameter through the control interface to match the required packaging cycle and sealing process.

• Defined Seal Widths: The equipment provides an 8 mm top seal and a 10 mm side seal as standard. Seal dimensions can be customized against the acceptance reference supplied by the user, allowing the sealing interface to be matched to verified process requirements.

• Uniform Sealing-Head Parallelism: Under the specified verification conditions, the sealing impression produced with triple carbonless copy paper is uniform. This gives buyers a practical basis for evaluating sealing-head alignment and pressure distribution during process confirmation.

• PLC and Touch-Screen Control: A programmable logic controller provides automatic control, while the touch screen supports operator dialogue and convenient parameter setting. Manual and automatic operating modes are included to support setup, normal operation, and functional checks.

• Process Alarm and Protection Functions: The unit includes low-temperature and high-temperature alarms, door-switch protection, fixture detection protection, and fault-alarm functions. These features support controlled operation by identifying abnormal conditions and protecting the sealing cycle.

• Production Output Statistics: An integrated production-counting function records output during operation. This gives production personnel a direct way to monitor completed packaging cycles and review operating output.

• Durable Profile Frame Construction: The frame uses aluminum-alloy profiles for a clean, structured equipment build. The mechanical arrangement is designed for stable program operation, reliable control, convenient operation, and a human-oriented interface.
