Product Description

The CM300 is designed to produce single PE / PLA or water-based biodegradable barrier materials coated paper bowls with a stable production speed of 60-85pcs/min. This machine is designed to produce paper bowls especially for food packaging, like chicken wings, salad, noodles, and other consumer products. It processes single PE / PLA, double PE / PLA, PE / Aluminum, or water-based biodegradable materials coated paper board.

Transmission

Fully oil lubrication for mechanical transmission system, guaranteeing the service life of the machine.
The mechanical transmission operates mainly by gears to two longitudinal shafts. The structure is effective, simple, and leaves ample room for maintenance. The main motor's output comes from both sides of the motor shaft for balanced force transmission.
Open type indexing gear (turret 10 : turret 8 arrangement) optimizes overall function. High-end IKO (CF20) heavy load pin roller bearings are used for the indexing gear cam follower, accompanied by digital pressure transmitters.

Humanized Structure

Folding wings, knurling wheel, and brim rolling stations are adjustable above the main table; no adjustment is needed inside the main frame.
Double-deck paper blank conveying and side sealing stations are designed with an optimized structure and width, making maintenance highly convenient.

Electrical Design

Electric control cabinet: The entire machine is managed by a high-end PLC, with independent frequency inverter control for all motors to adapt to a wide range of paper characteristics.
Heaters use a well-known brand, complemented by ultrasonic heating for side seam sealing.
Faults such as low paper level, missing paper, or paper-jams will display precisely in the touch panel alarm window.
All electrical components utilize reliable international brands for superior performance and longevity.
