50mm to 600mm Aluminum Plastic Film Slitting and Cutting Machine

Product Overview

This system is designed for longitudinal slitting and roll cutting of aluminum plastic film used for soft-pack lithium battery packaging. It processes a full-width roll up to 600 mm wide through blade-based longitudinal cutting, then uses two motor-synchronized winding rollers to rewind the separated material. The result is aluminum plastic film prepared to the required production-process width with controlled handling from feed through collection.

The equipment is suited to battery R&D lines, pouch-cell pilot production, and manufacturing processes that need to divide wide aluminum plastic film into narrower packaging-film strips. Its minimum slitting width of 50 mm supports a broad practical range of cut formats, while the eight blade sets provide the cutting configuration required for multi-strip processing from one loaded roll.

A variable-frequency motor and winding motor form the primary control arrangement, providing stable control performance with adjustable operating speed. A high-power motor drives the knife roller, while the active speed-regulation winding arrangement is intended to maintain material-strip tension. Adjustable tension and cutting-roll speed give operators direct control over material handling conditions when preparing film for demanding battery packaging workflows.

Key Features

• 50 mm to 600 mm Slitting Range: The equipment slits aluminum plastic film from a minimum width of 50 mm up to 600 mm. This range supports the conversion of full-width material rolls into packaging-film widths required by the production process.

• Longitudinal Blade Cutting: Eight blade sets perform longitudinal slitting after the roll is loaded. The cutting arrangement is built around a knife roller driven by a high-power motor to support controlled separation of the film into multiple strips.

• Specified Cutting Accuracy: The system provides a slitting accuracy of +/-0.5 mm. This defined accuracy helps production teams control the resulting film width when preparing material for soft-pack lithium battery packaging.

• Synchronized Dual-Roller Rewinding: Two winding rollers are synchronously driven by motors after longitudinal cutting. This coordinated collection arrangement rewinds the separated film strips following the selected cutting width.

• Adjustable Material Tension: Tension can be adjusted from 0 to 25 N according to actual operating conditions. The active winding arrangement is configured to keep the material strip under controlled tension during the slitting and rewinding process.

• Variable Cutting-Roll Speed: The cutting-roll speed is adjustable from 0 to 30 m/min according to actual requirements. Operators can set a suitable processing pace for the film-handling condition and production workflow.

• Adjustable Collection Speed: Material collection speed can be adjusted according to actual conditions. This flexibility supports coordinated operation between the cutting section and the rewinding section.

• Robust Mechanical Construction: The platform base uses 45# steel plate with a chrome-plated surface. Painted cover plates, reinforcing plates, and square-tube components form the main frame structure, while the unit also includes a safety protection plate.

• SKD11 Slitting Blades: The slitting knives are made from SKD11 material. The blade material is specified as part of the core cutting configuration for aluminum plastic film processing.

• Straightforward Motor-Control Arrangement: A variable-frequency motor and winding motor serve as the primary control components, with stable control performance and adjustable fast and slow operation. The system is designed for direct, convenient operation during film conversion.

Why Choose This Product

• Defined Precision for Film Preparation: The specified +/-0.5 mm slitting accuracy gives procurement and process teams a clear benchmark for width control when converting aluminum plastic film for soft-pack battery packaging.

• Capacity Matched to Full-Width Material: With a maximum loading width of 600 mm and maximum loading diameter of 350 mm, this system is configured for processing wide aluminum plastic film rolls before they are divided into narrower strips.

• Controlled Handling from Cut to Rewind: The combination of blade slitting, two synchronized winding rollers, adjustable collection speed, and 0 to 25 N adjustable tension supports a controlled material path through the cutting and rewinding operation.

• Specified Industrial Build Elements: A chrome-plated 45# steel plate base, reinforced painted frame construction, SKD11 blades, and an equipment safety protection plate define the mechanical configuration of the unit.

• Practical Operating Adjustability: Adjustable cutting-roll speed from 0 to 30 m/min, adjustable tension, and variable collection speed allow the equipment to be set according to actual production conditions rather than operated at one fixed setting.
