Wood chip pallet hydraulic press is a special equipment specially used to mix wood chips (or wood fiber, straw and other agricultural and forestry wastes) with adhesive and then press and mold them into wood chip pallet through high-pressure hydraulic technology. Wood chip pallet is an environmentally friendly packaging/carrying tool, widely used in logistics, warehousing, manufacturing and other fields, can replace the traditional wooden pallet, plastic pallet, with low cost, recyclable, lightweight, moisture-proof and other characteristics.
The workflow of the wood chip pallet hydraulic press can be divided into the following steps:
Raw material preparation: Crush the remaining wood chips (or straw, bamboo chips, etc.) from wood processing to a uniform particle size (usually 2-5mm), and mix with thermoplastic adhesives (such as urea-formaldehyde resins, isocyanate adhesives) or inorganic adhesives (such as cement, gypsum) according to the ratio of If necessary, add waterproofing agent (e.g. paraffin emulsion) to improve the moisture resistance.
Filling and pre-pressing: The mixed material is filled into the lower mold through the feeder, and the main cylinder slowly descends for pre-pressing (to eliminate air initially and reduce rebound).
High pressure pressing: the main cylinder continues to pressurize to the set pressure (e.g. 8-30MPa), holding pressure for a period of time (according to the demand of adhesive curing, usually 5-30 seconds), so that the material is tightly fit under high pressure, and the adhesive is cured and molded.
Demolding and discharging: the ejector cylinder rises to eject the molded pallet from the lower mold, and it is taken away manually or by robotic arm to enter the subsequent trimming and inspection process.
I. Raw material preparation Choose suitable raw materials, such as wood shavings, plant straw and so on. Preliminary processing of raw materials, including cutting, chipping and other steps for subsequent crushing and mixing.
2, crushing and mixing The preliminary processed raw materials are crushed to the appropriate particle size and automatically proportioned for transfer as required. Mixing of the proportioned raw materials with adhesives. The mixing process should ensure that the adhesive is evenly distributed in the raw material to improve the strength and stability of the pallet.
3, drying and cooling The mixed raw materials are dried at high temperature to reduce their moisture content to ensure the stability and quality of the pallet in the moulding process. After drying, the raw material should be cooled for subsequent moulding operations.
4.Moulding The dried and cooled mix is conveyed to the laying machine in set quantities. The spreader spreads the mix evenly in the mould in preparation for moulding. A hydraulic press for wood chip pallets is used to apply high temperature and pressure to the mix in the mould. The hydraulic press provides a strong compressive force that binds and cures the mix in the mould. After moulding, the pallet is automatically removed from the mould.
Molded pallet hot press is a new type of molded pallet production equipment, the use of hot pressing process of one-time molding, pallet hydraulic press has the advantages of high efficiency, one-time molding, material saving, high strength, environmental protection and energy saving. Depending on the size of the pressed pallet flower pattern, can be configured with different molds, specific can consult customer service.
