The wood pallet block machine can process wood chips, shavings, and other waste materials into standard or customized size pads (density 550-1000kg/m³) through a modular hot press molding system.
The machine has fumigation-free certification and 48-hour waterproof and crack-resistant characteristics, and is equipped with intelligent CNC molds (supporting full-size customization from 75-145mm). It is suitable for 20+ application scenarios, such as building shock absorbing substrate, logistics pallet footing, and precision equipment packaging support.
The equipment is easy to operate, and one person can manage multiple equipment at the same time. Single pallet block machine can reach 4-5m³ / day super processing capacity (annual processing of waste wood up to 1500 tons), suitable for all kinds of enterprises’ batch production.
Wood sawdust pallet block machine advantages
- Strong adaptability of raw materials: it can handle a variety of types, shapes and sizes of raw materials to meet different customer needs.
- High degree of automation: automated production process reduces manual labor intensity and improves the working environment.
- Flexible replacement of molds: molds and parameters can be quickly adjusted to adapt to the production of different specifications of pads.
- Strong production flexibility: customized finished products of various sizes and types can be applied to multiple industries.
- Fumigation-free treatment: products are extruded and molded through high temperature, no fumigation is required, which meets the export standard.
Characterization of raw materials and finished products
The core raw material of the wood pallet block machine is 3-5mm wood shavings, which mainly come from the following two types of processing:
- Wood processing waste: including sawdust (processed by 木材粉砕機/hammer mill), wood shavings (produced by wood shaver machine), and edges from furniture factories and wooden pallet production.
- Agricultural biomass: can be mixed with rice husk, wood chips, and other auxiliary materials, and add 10%-15% of environmentally friendly adhesives.
The finished blocks are divided into solid type and hollow type. By switching the molds, we can support 75-145mm full-size customization (e.g. 80×80mm standard type, 120×140mm shaped block).
Wood sawdust block press machine working principle
Raw material pretreatment
- Screening and crushing: raw materials (wood chips, shavings, rice husk, etc.) need to be processed by crusher to 3-5mm particle size, and remove impurities through three-stage screening.
- Drying and humidity control: the moisture content of raw materials is reduced to less than 12% by drying machine to ensure the effective penetration and curing of adhesive.
- Glue mixing and blending: apply glue evenly in the mixing device at a ratio of 10%-15% to prevent lumping of raw materials and improve the density uniformity.
Hot press molding
- Hydraulic drive: the hydraulic cylinder applies high pressure of 50-100MPa and drives the piston to push the mixture into the mold to form a continuous strip with a density of 550-1000kg/m³.
- High-temperature curing: the mold has a built-in electric heating plate (120-180℃), which accelerates the curing of the adhesive and improves the internal bonding strength (≥1.07MPa) and cracking resistance (no cracking after 48 hours of soaking in water) of the blocks.
- Mould adaptation: support 75×75mm to 140×145mm full-size customization, through the replacement of molds to achieve solid/hollow, with holes/no holes, and other structural switches.
Cutting and cooling
- Cutting at fixed length: the long strip after hot pressing molding is cut into 1.2m standard segments by automatic cutting machine, with cutting error ≤±1mm.
- Natural cooling: the cut semi-finished products are cooled in a ventilated environment for 24 hours to eliminate internal stress and ensure dimensional stability.
Finishing and slitting
- Precision cutting: after cooling, the long strip is processed twice by CNC cutting machine to produce the final specification pads (e.g. 80×80mm, 100×100mm, etc.).
- Split block optional: support on-demand slitting into small-sized blocks (such as 30 × 30mm), suitable for furniture manufacturing, precision packaging and other scenarios, production efficiency of up to 1,800 blocks/hour.
