Desktop Continuous Film Coating Testing Machine for 18650 Cylindrical Batteries

Product Overview

This desktop continuous coating testing machine is a modular laboratory coating system designed for continuous electrode coating trials and small-batch production. It combines adjustable unwinding tension, mechanical rewinding tension control, precision scraper-gap adjustment, and an integrated drying oven in one compact platform. The system is intended to support repeatable coating development without the footprint or complexity of a full industrial coating line.

The equipment is primarily designed for continuous coating of lithium-ion battery cathode and anode slurries. It is suitable for electrode development related to 18650 cylindrical battery research, as well as university laboratories, corporate R&D centers, and small-scale process validation. The same platform can also process ceramic thin films, crystal films, and specialized nanofilms.

A stainless steel machine body provides a durable laboratory-grade structure for repeated operation. The surface is spray treated for improved appearance and practical protection, while independent high-precision PID temperature control supports stable drying conditions up to 100°C. Adjustable coating width, material compatibility, and stepless speed control allow researchers to evaluate a broad range of formulations and process settings.

Key Features

• High-Precision Modular Architecture: The complete system uses a modular coating-station structure assembled for laboratory-scale process control. This configuration supports organized operation, easier process adjustment, and consistent integration of coating, drying, and winding functions.

• Precision Coating-Gap Adjustment: A fine adjustment mechanism controls the upper scraper coating gap. The adjustable gap enables wet coating thickness control from 0.01 mm to 2 mm, helping users investigate slurry loading and film formation conditions with greater precision.

• Adjustable Unwinding Tension: The feed roll shaft uses an adjustment knob and screw to modify unwinding tension. This helps accommodate different substrate conditions and maintain stable material feeding during continuous operation.

• Mechanical Rewinding Tension Control: The take-up roll shaft provides mechanical tension adjustment for collection. Controlled rewinding supports cleaner handling of coated foil and reduces inconsistencies caused by loose or excessive winding tension.

• Variable Coating Width: The coating width can be adjusted from 50 mm to 150 mm using two internal guide plates. This makes the unit suitable for narrow laboratory samples, formulation screening, and wider small-batch coating trials.

• Continuous Coating and Automatic Take-Up: The system can continuously coat positive and negative electrode slurry over unlimited material length within the available feed stock, followed by automatic roll collection. This supports extended trials and reduces manual handling between coating sections.

• Stepless Operating Speed: Coating speed is specified at 2 m/min with stepless variable-speed operation. Users can fine-tune line movement to evaluate the relationship between coating speed, slurry behavior, drying, and final film quality.

• Independent PID Oven Control: The 1100 mm drying oven uses an independent digital temperature controller with high-precision PID regulation. The maximum operating temperature is 100°C, providing controlled drying conditions for laboratory coating development.

• Durable Stainless Steel Construction: The machine body is made entirely from stainless steel and receives a spray surface treatment. The construction is attractive, durable, and appropriate for repeated use in battery, materials science, and academic research environments.

Applications

Technical Specifications

The coating section is configured for laboratory-scale adjustment of the principal variables that influence electrode and thin-film quality. The scraper gap provides direct control over coating thickness, while internal guide plates determine the active coating width. Together, these adjustments allow the operator to match the coated area to the test substrate and material quantity being evaluated.

The feed and collection mechanisms are designed for continuous web handling. The unwinding roll uses a knob-and-screw adjustment for tension, while the take-up roll provides mechanical tension control during rewinding. This arrangement is important when working with thin aluminum or copper foil, because stable material movement helps reduce wrinkles, slack, and unnecessary handling during extended trials.

The integrated oven provides an 1100 mm drying path within the compact machine layout. Independent PID temperature regulation and a digital display allow the operator to set and monitor the drying temperature, up to the specified maximum of 100°C. This gives researchers a controlled environment for examining the influence of drying conditions on coated film development.

With a 50 mm to 150 mm adjustable coating width and a 0.01 mm to 2 mm coating-thickness range, the equipment can accommodate a broad laboratory development window. The supported aluminum foil thickness is 0.01 mm to 0.03 mm, while copper foil thickness is 0.006 mm to 0.020 mm. These ranges align with common laboratory electrode-coating activities while also supporting non-battery thin-film work.

The compact 1800 × 350 × 580 mm machine footprint is suitable for laboratories that need continuous coating capability but have limited floor space. At approximately 130 kg, the unit provides a substantial stainless steel platform while remaining practical for installation in dedicated research areas. The stated packaging dimensions and weight should be considered during delivery planning, laboratory access review, and equipment handling arrangements.
