400mm Aluminum Plastic Film Pouch Top Side Edge Trimming Machine Battery Pneumatic Trimmer

Product Overview

This pneumatic edge trimming machine is designed for trimming the top-side sealed edge of aluminum plastic film after pocket forming. It combines cylinder-driven punching with matched upper and lower cutters to provide a controlled finishing operation for pouch-cell processing. The equipment supports a 400 mm cutter length and adjustable trimming widths, allowing operators to prepare formed film edges with a defined, repeatable cut.

The unit is intended for battery laboratories, pilot lines, cell-development work, and production processes that use aluminum plastic film packaging. An operator holds the battery at the positioning plate and actuates the foot pedal to complete trimming. This direct operating method supports efficient handling during pouch-cell assembly and finishing, where edge geometry must be managed before subsequent process steps.

Reliable mechanical guidance is central to the equipment design. The upper cutter is guided by die-style ball guide pillars and guide bushes, maintaining high guiding accuracy between the upper and lower cutters. High-speed-steel cutting edges, a specified hardness of HRC>=58, and a zero-clearance cutter arrangement provide a robust basis for repeated pneumatic cutting operations under demanding cell-processing conditions.

Key Features

• 400 mm Cutter Length: The cutter is configured for material widths up to a 400 mm cutter length, supporting aluminum plastic film trimming after pocket forming and top-side sealing operations.

• Pneumatic Punching Action: A cylinder-driven punching method supplies the cutting action. The system requires an air supply of at least 0.5 MPa for operation.

• High-Accuracy Cutter Guidance: Die-style ball guide pillars and guide bushes guide the upper cutter. This arrangement is specified to maintain high guiding accuracy and preserve zero clearance between the upper and lower cutters.

• High-Speed-Steel Cutters: Both the upper and lower cutters are made from high-speed steel. Their sharp cutting edges are intended for clean, controlled edge removal during the trimming process.

• HRC>=58 Cutter Hardness: The cutting tools are specified with a hardness of HRC>=58. This material requirement supports cutter durability in repeated trimming work.

• Adjustable Trimming Width: A positioning stop edge adjusts the trimming width from 2.5 mm to 8 mm. The adjustment gives users a practical range for matching the finished edge to process requirements.

• Specified Trimming Precision: The equipment provides trimming precision of ±0.2 mm. This defined tolerance helps process teams evaluate the unit against their pouch-edge finishing requirements.

• Foot-Pedal Control: A foot switch controls cutter movement. The operator can hold the battery in position with one hand, place it against the positioning plate, and use the foot pedal to initiate the trim.

• Integrated Positioning Plate: The battery positioning plate forms part of the mechanical assembly and establishes the reference location for the workpiece before cutting. It works with the adjustable stop edge to control the trim width.

• Compact Electrical Configuration: The electrical system includes a solenoid valve and foot switch, with AC220V/50HZ power configuration and 500 W rated power. The arrangement supports the pneumatic actuation sequence without a complex operating interface.

Why Choose This Product

• Purpose-Built for Pouch Edge Finishing: This unit is specifically configured for trimming the top-side sealed edge of aluminum plastic film after pocket forming, rather than applying a general-purpose cutting method to a specialized battery-packaging task.

• Precision-Led Mechanical Alignment: The ball guide pillar and guide bush structure is designed to maintain high upper-cutter guidance accuracy and zero clearance between the cutter pair. This construction directly supports the specified ±0.2 mm trimming precision.

• Durable Cutting Construction: High-speed-steel upper and lower cutters with HRC≥58 hardness provide a robust cutting-tool specification for repeated pneumatic trimming duties. Sharp cutting edges support the defined trimming process.

• Adjustable for Process Requirements: The 2.5-8 mm trimming-width range allows the equipment to be set using its positioning stop edge, helping laboratories and manufacturing teams align edge finishing with their required pouch configuration.

• Straightforward Operator Control: The positioning plate and foot-switch control method create a clear work sequence: locate the battery, hold it in place, and actuate the cut. The electrical configuration of solenoid valve, foot switch, AC220V/50HZ supply, and 500 W power supports this focused operating design.
