Coconut shell pallet production line is an automated manufacturing system that uses coconut shell fiber as the core raw material and realizes the resource utilization of coconut shells through crushing, mixing, molding/injection molding and post-processing. Its core process integrates agricultural and forestry waste treatment and composite material molding technology, adapts to the production needs of standardized pallets (such as dynamic load ≥1.5 tons, static load ≥5 tons), and supports customized structural design.
The coconut shell pallet production line converts waste coconut shells into high-value-added logistics vehicles, with a raw material utilization rate of ≥90%, reducing the dependence of traditional plastic pallets on petroleum-based raw materials; it is compatible with recycled plastics (such as PE) and bio-adhesives to meet the needs of the circular economy.
Coconut shell pallet production uses coconut shell fiber as the core raw material, combined with molding or injection molding technology to achieve efficient resource utilization. Its process flow can be divided into the following stages:
I. Raw material pretreatment
Coconut shell crushing : Use a comprehensive crusher to crush the coconut shell into particles ≤2cm to ensure the uniformity of subsequent mixing and molding. If the moisture content of the coconut shell is greater than 15%, it needs to be controlled to less than 3% through a drum dryer to avoid bubbles during the molding process.
Fiber screening : Impurities (such as coconut shell inner membrane, gravel) are removed through vibration screening equipment, and clean coconut shell particles with a fiber length of ≤5mm are retained.
II. Mixing and gluing
Proportion mixing : Coconut shell fiber accounts for 60-80%, with thermoplastic plastic particles (such as HDPE, PP, accounting for 20-40%) or bio-based adhesives (such as starch glue). Add a coupling agent to enhance the interfacial bonding between the fiber and the matrix.
Glue mixing process: Use a high-speed mixer to mix coconut shell particles and adhesive (urea-formaldehyde resin or epoxy resin). The mixing temperature is 70-80℃, and the time is ≥20 minutes.
III. Molding process
Molding: After the mixture is filled into the mold, it is hot-pressed by a hydraulic press at a pressure of 1600-2000 tons. The mold temperature is 180-200℃, the pressure holding time is 6-8 minutes, and the tray base is formed after cooling and demolding.
Main Machines of Production Line: Wood Chipper, Wood Crusher, Drying Machine, Glue Mixer, Presswood Pallet Machine, Mold Temperature Controller.
Automatic material spreading, automatic hot pressing, automatic push-out and automatic stacking. can produce 180 pieces of wood pallet per hour.
Fully automated production solutions. In the entire production line, only one or two staff members are needed to handle normal operations.
Reusing waste wood, sawdust, wood chips, straw, coconut fiber (coir) and other fibers can significantly reduce the cost of raw materials.
The pressed wood pallet is of high quality with smooth surface, high loading capacity, good performance in water proof resistance and non-fumigation.
By simply changing the compression molding, pallets in varied shapes/sizes could be produced. Meet the needs of various uses.
Heat sources can be supplied in a variety of ways. The energy consumption is low. It is an ideal option to recycle wood waste in an environmentally friendly way.
