Aluminum Plastic Film Slitting and Segment Cutting Machine for Pouch Lithium Batteries

Product Overview

This system is engineered for slitting and length cutting aluminum-plastic laminate film used in pouch lithium battery packaging. It processes a full-width roll through longitudinal blade slitting, then advances the material to the cutting station at a programmed length. The resulting film sections support preparation of packaging material that conforms to production-process requirements. The integrated arrangement combines roll handling, tension management, slitting, feeding, and segment cutting in one purpose-built unit.

The equipment is suited to pouch-cell manufacturing workflows that require repeatable preparation of aluminum-plastic film before packaging and cell assembly. It accommodates material widths from 55 mm to 500 mm and segment lengths from 10 mm to 500 mm, allowing operators to prepare different film formats from a maximum 500 mm wide roll. This makes the unit relevant to battery research lines, pilot-scale development, and production operations handling flexible pouch packaging materials.

Reliability is supported by a PLC and touchscreen control architecture, a high-power stepper-motor feed drive, and a motorized active unwinding arrangement. The unwinding system is designed to maintain constant web tension, which is essential to dependable feed behavior and segment-cutting accuracy. A robust steel-frame construction, corrosion-resistant nitrile rubber rollers, and an SKD11 cutting blade provide a durable mechanical basis for recurring material conversion work.

Key Features

• Integrated Slitting and Segment Cutting: The equipment longitudinally slits a full roll and subsequently advances the film to the cutting position at the selected length. This integrated process prepares finished packaging-film sections directly from roll stock while reducing unnecessary material handling between operations.

• Controlled Web Tension: A speed-regulated motor drives active unwinding to maintain constant material-belt tension during operation. Stable tension helps the film travel consistently through the rollers and cutting path, supporting reliable cutting results across the usable roll width.

• High-Precision Length Cutting: The segment-cutting accuracy is specified at ±0.1 mm. This level of control supports pouch-film preparation where repeatable section length is important for downstream packaging processes and process standardization.

• Flexible Format Range: Slitting width can be set from a minimum of 55 mm up to 500 mm, while segment length is adjustable from 10 mm to 500 mm. The broad working range enables the same unit to support varied pouch-film dimensions within a battery manufacturing workflow.

• Stepper-Motor Material Feed: A high-power stepper motor drives two rollers that feed the aluminum-plastic film toward the cutting blade according to the programmed length. The controlled roller feed is central to orderly material advancement and accurate repeated segment cutting.

• PLC and Touchscreen Operation: The primary controls consist of an imported PLC and touchscreen human-machine interface. This configuration provides stable control performance and a direct, visual operating interface for setting and managing the conversion process.

• Durable Cutting and Roller Components: The segment-cutting blade is manufactured from SKD11 material. Nitrile rubber rollers are corrosion resistant and designed to resist deformation, helping maintain reliable material contact and transport over repeated processing cycles.

• Rigid Machine Structure: The main frame uses a 45# steel base plate with a chrome-plated surface, together with painted cover plates, reinforcing plates, and square-tube frame members. This structural approach provides a stable platform for roll handling, feed motion, and cutting operations.

• Production-Oriented Output: Depending on the selected segment-cutting length, the equipment delivers approximately 3,000 to 12,000 pieces per hour. Operators can balance output requirements with the selected finished-film format while retaining the specified cutting accuracy.

Why Choose This Product

• Process-Focused Mechanical Design: This unit integrates the key material-conversion stages required for pouch aluminum-plastic film preparation: controlled unwinding, longitudinal slitting, programmed feeding, and segment cutting. The configuration is designed around the actual sequence required to turn roll material into usable packaging-film sections.

• Precision Where It Affects Production: The specified ±0.1 mm segment-cutting accuracy, combined with stepper-driven roller feeding and constant-tension material handling, focuses machine performance on repeatability. This is valuable where packaging-film dimensions must be managed consistently across recurring cell-production operations.

• Built for Repeated Material Handling: A chrome-plated 45# steel base plate, reinforced painted structure, SKD11 blade, and nitrile rubber rollers provide a robust component set for industrial processing. The selected roller material is corrosion resistant and non-deforming, supporting stable transport characteristics over continued use.

• Practical Operating Interface: PLC and touchscreen control provide stable performance with direct visual operation. This makes the system suitable for teams that need to set cutting lengths, manage film conversion, and maintain a clear operating process on battery R&D, pilot, or production lines.

• Output Flexibility Without Compromising Capability: With a 55 mm to 500 mm slitting-width range, 10 mm to 500 mm cutting-length range, and approximately 3,000 to 12,000 pieces per hour capacity depending on cut length, the equipment supports a broad range of pouch-film preparation requirements from one installed platform.
