Pouch Cell Edge Cutting Folding and Heat Sealing Forming Machine

Product Overview

This system is designed for integrated edge cutting, edge folding, and heat-sealing forming of lithium pouch cells. It combines these sequential operations in one controlled production process, helping manufacturers produce accurately finished cell edges while reducing handling between process stations. Symmetrical, adjustable cutting and forming modules support controlled setup for different cell widths.

The equipment is suited to lithium pouch-cell production, including processes requiring removal of excess edge material followed by folded and heat-sealed edge formation. An operator loads cells onto the synchronized conveyor at the feed area, while the unit advances them through trimming, clamping, forming, and unloading positions in an intermittent sequence.

Built around coordinated mechanical movement, digital temperature control, PLC automation, and touchscreen operation, this unit is engineered for stable day-to-day processing. Its changeable fixtures, feed belts, and timing pulleys provide a practical route for adapting the equipment when the product specification changes.

Key Features

• Integrated Three-Step Processing: The equipment combines edge trimming, folding, and heat-sealing forming in a continuous operational sequence. Cells progress from manual loading through cutting, clamping, heated forming, and manual unloading, supporting an organized workflow for pouch-cell edge finishing.

• Intermittent Synchronized Belt Feeding: A carrier synchronous belt advances cells by intermittent stepping through each working position. This arrangement gives operators convenient access for loading and removal while maintaining controlled transfer between the cutting, clamping, and forming stages.

• Adjustable Symmetrical Cutting Modules: The cutting mechanism uses a symmetrical modular arrangement with an adjustable distance between cutting elements. This enables the unit to accommodate pouch cells of different widths within its supported processing range without changing the fundamental operating principle.

• Fast Trimming with Cell Restraint: The rapid cutting assembly incorporates edge pressing and cell-compression functions. These functions support controlled trimming while the cell is held in position, helping the process achieve the specified cutting accuracy and reduce variation during edge-material removal.

• Precision Cutting Geometry: The cutting system provides a trimming accuracy of ±0.10 mm, cutter parallelism of 0.05 mm, and cutter hardness of HRC≥58°. The specified cutter life is 1 million cycles before grinding, supporting planned maintenance of a critical production component.

• Infeed and Outfeed Detection: Photoelectric sensors detect cell entry and exit at the cutting mechanism. This detection capability supports the automatic control sequence and helps coordinate cell movement through the processing positions.

• Adjustable Conveyor and Forming Spacing: Both the loading conveyor's left-to-right spacing and the symmetrical forming mechanism's spacing can be adjusted. The forming modules are adjusted through sliding seats, allowing setup to be aligned with the applicable cell width and the required fixture arrangement.

• Heated Copper-Mold Forming: A channel formed by heated copper molds performs the folding and heat-sealing operation while the cell is carried in a chain-mounted forming fixture. The heating range extends from room temperature to 200°, enabling the operator to set the temperature for the specified pouch-cell edge-sealing process.

• Controlled Forming Alignment: Copper-mold parallelism and verticality are each specified at 0.1 mm. These mechanical alignment values support consistent passage of the fixture through the heated forming channel and controlled edge-forming conditions.

• Digital Temperature Management: A digital temperature controller provides direct, visible temperature settings with an error of ≤2°. This makes the heating condition straightforward to monitor during setup and production, while supporting repeatable operation of the heat-sealing stage.

• PLC and Touchscreen Control: A programmable logic controller manages automatic control, with touchscreen human-machine interaction for operating settings. Manual and automatic operating modes are available, and the control system includes production counting for routine process management.

• Practical Product Changeover: When changing products, the process can be adapted by replacing the fixture, feed belt, and synchronous pulley and making the associated adjustments. Fixture dimensions are supplied to suit the ordered cell type, supporting application-specific configuration.

• Coordinated Operating Motion: The cutting and forming mechanisms operate synchronously and smoothly. Overall machine speed can be adjusted through a frequency converter, allowing the operating speed to be set according to the production requirement.

• Cell Appearance Protection: The process is intended to deliver good product consistency and avoid differences caused by abrasion or collision marks on the cell exterior. This is particularly relevant where pouch-cell appearance and edge condition require controlled handling from feed through unloading.

Technical Specifications

Why Choose This Product

• Defined Mechanical Accuracy: Critical cutting and forming values are specified, including ±0.10 mm cutting accuracy, 0.05 mm cutter parallelism, and 0.1 mm copper-mold parallelism and verticality. These measurable parameters give procurement and process teams a clear basis for evaluating the equipment's working precision.

• Process Integration for Pouch Cells: Cutting, clamping, folding, and heat-sealing are arranged as connected stations within one unit. This configuration supports a consistent process flow from manual loading to manual take-out, rather than treating each edge-finishing operation as an isolated task.

• Durable Cutting Components: The cutter specification combines HRC≥58° hardness with a stated life of 1 million cycles before grinding. This provides a practical durability reference for a component central to trimming performance and maintenance planning.

• Adaptable Production Configuration: Adjustable module spacing, adjustable conveyor spacing, order-matched fixtures, and a defined replacement method for fixtures, belts, and pulleys support use across applicable cell formats. The frequency converter also provides straightforward control of overall operating speed.

• Operator-Focused Control and Stability: Digital temperature display, PLC automation, touchscreen interaction, manual and automatic modes, photoelectric detection, and production counting provide the control functions needed for routine operation. The coordinated cutting and forming mechanisms are designed for stable, safe, reliable, and convenient use.
