Wood-plastic composite product compression moulding and pre-spreading method and wood-plastic composite product compression moulding and pre-spreading system

Abstract

The invention discloses a wood-plastic composite product compression moulding and pre-spreading method and a wood-plastic composite product compression moulding and pre-spreading system. The wood-plastic composite product compression moulding and pre-spreading system comprises an extruder, a metering device, a pre-spreading manipulator, a heat preservation conveying belt, a feeding manipulator anda moulding press; the extruder and the metering device meter the quantity of required wood-plastic composite blocks output for compression moulding according to the product requirements of a machinedproduct; the wood-plastic composite blocks are spread in a designated position; and a group of wood-plastic composite blocks are synchronously transferred to a to-be-fed station, the group of wood-plastic composite blocks arriving at the to-be-fed station are sent into a mould cavity of the moulding press at one time, and a compression moulding process is completed by the moulding press. The moldability of a wood-plastic composite is ensured, the quality of a wood-plastic composite product is improved substantially, the machining efficiency is improved, and the wood-plastic composite productcompression moulding and pre-spreading method and the wood-plastic composite product compression moulding and pre-spreading system are economical and environmentally friendly, and have wide application fields and development prospects.

Description

technical field [0001] The invention belongs to the technical field of material forming, and in particular relates to a pre-laying method and system for molding wood-plastic composite material products. Background technique [0002] With the improvement of people's awareness of environmental protection and the country's advocacy of circular economy and sustainable development, wood-plastic composite materials have attracted people's attention. It not only maintains the high strength and high elasticity of wood fiber or plant fiber, but also has the high toughness and fatigue resistance of thermoplastic polymer materials, can be recycled, and is economical and environmentally friendly. [0003] In the molding process of traditional wood-plastic composite products, one-mold multi-cavity processing technology is used. Although the processing rate can be improved, because the wood-plastic composite material blocks have been laid many times, the molded parts that enter each mold ...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, to provide a wood-plastic composite product molding pre-laying method, which replaces a large-sized single block with a plurality of smaller-sized blocks scattered and placed , to solve the problem that large-sized products are difficult to form when using a single large-size block, which can effectively reduce the rate of its products and improve processing quality and processing efficiency
