What is Rotary pulp molding machine?

A rotary pulp molding machine is a type of equipment used to manufacture molded pulp products, which are eco-friendly alternatives to plastic packaging. These machines use a rotary molding process to create items from recycled paper pulp, such as egg trays, cup holders, and various types of containers.

Components and Functions

Pulp Preparation System:

Pulping Machine: This component shreds and processes waste paper into a slurry of paper fibers and water. The quality of the pulp affects the final product, so this stage is crucial.
Pulp Pump: Moves the prepared pulp from the pulping machine to the molding section. It ensures a steady flow of pulp to the molds.
Pulp Storage Tank: Stores the pulp mixture, keeping it at the right consistency and temperature until it’s needed for molding.


Rotary Molding Unit:

Rotary Mold: The core component of the machine, the rotary mold consists of multiple cavities that rotate in a circular motion. This rotation allows for continuous molding and efficient production.
Molding Station: Here, the pulp is distributed into the mold cavities. The rotary motion ensures uniform distribution and filling of the cavities.


Drying System:

Drying Oven: After molding, the wet pulp products need to be dried to harden them. The drying oven uses heat to evaporate the moisture from the products.
Drying Conveyor: Moves the molded products through the drying oven. It ensures that products are evenly exposed to heat for consistent drying.


Release and Finishing:

Mold Release Mechanism: Once the products are dried, they need to be removed from the molds. This mechanism ensures smooth and efficient release without damaging the products.
Trimming and Cutting: Excess material is trimmed, and products are cut to their final size. This step ensures that the finished products meet specific size and quality standards.


Control System:

PLC (Programmable Logic Controller): The control system manages the operation of the machine. It coordinates various stages of production, from pulp preparation to molding and drying, ensuring precise control and automation.
