Product Details

1. Scope of Application:

Suitable for baking entire rolls of lithium-ion battery electrode.

2. Configuration

A. Chamber Body: Made of 3.5mm imported 304 stainless steel, reinforced ribs are made of the same material.

B. Frame: Constructed from 1.5mm and 2.0mm high-quality cold-rolled steel plates, composed of two-layer insulation, with layered construction of aluminum silicate wool, aluminum foil wool, and soundproofing wool.

C. Hot Air System: Each layer consists of fan, heating box, air duct, and air pipe, ensuring temperature uniformity.

D. Control System: Composed of PLC, Weinview touchscreen, KITA pressure sensor, high vacuum gate valve, solid-state relay, temperature controller, electromagnetic valve group, etc.

E. Hardware Components: Includes doors, rear cover, vacuum pipes, and other stamped parts.

3. Machine Features

A. Fully sealed heating channels with breathing-type heating process, high efficiency and energy-saving, high temperature accuracy.

B. High-vacuum pneumatic gate valve, independently controlled dual-chamber isolation.

C. Standardized six-fold high-performance safety protection across all models.

D. Aluminum alloy doors, elastic double-layer glass doors, excellent heat retention and explosion-proof performance, equipped with dual-layer pressure detection and overpressure protection.

E. Equipped with 7-inch full-color touchscreen HMI system across all models, elegant and intuitive.

G. Material Loading Method: Suspended on a ∅63mm hanging shaft in the center of the inner chamber, maximum load ≤150kg.

H. Chamber Structure: Double-door, single-opening door.

I. Insulation Structure: Uses high-density aluminum silicate insulation wool, double-layer thermal insulation, external temperature below 45°C (excluding glass doors).

J. Heating Method: Electric heating control, external loop-type hot air circulation.

K. Heating Structure: Uses O-type external circulation – air outlet on the left, suction on the right, to achieve temperature uniformity.

L. Touchscreen display, automatic circulation and control, automatically returns to vacuum holding at the end; digital display of safety temperature.

M. Equipped with multi-level over-temperature protection, effectively prevents temperature control failure and enhances accuracy of protection.

N. Control panel adopts centralized touchscreen operation, convenient and reliable control. Program controller adopts PLC control, stable and reliable operation.

O. The two-barrel oven is independently controlled, can set total baking time, cycle time, vacuum time, drying time separately. After setting parameters, pressing the auto button will enter the automatic baking program. When the baking time is reached, the system will automatically shut down. If the temperature exceeds the safety limit, it will automatically alarm, the red indicator light turns on, heating stops, and the alarm information is displayed on the screen.

P. During normal operation, fault warnings and causes can be displayed on the screen in real-time.

6. Six-Fold Safety Protection

1. Explosion-proof door, never ruptures; equipped with overpressure self-release to protect operator safety.

2. Dual-layer over-temperature protection in working chamber (to protect products); power is cut off automatically when over-temperature is detected.

3. Over-current and short circuit protection for control system.

4. Over-current and short circuit protection for heating tubes and motors.

5. When chamber is overcharged, the system will automatically shut off nitrogen & dry gas inlets, saving gas and reducing losses.

6. Independent alarm system: audio-visual warning is issued when baking time is reached, alerting operators.
