Embodiment 1

[0042] Such as figure 1 As shown, the continuous production system of laminated biomass composite materials provided in this embodiment includes melt film forming device 1, fiber material conveying device and melt film conveying device 2;

[0043] Melt film molding device one comprises screw extruder 1, forming roll one 2 and cylinder one 3 pressed with forming roll one 2; The conveying device, the three-dimensional vibrator 14 is arranged below the conveying device; the conveying device includes a conveyor belt 11 and a pair of dispersing rollers 13 arranged on the upper and lower sides of the conveyor belt 11 .

[0044] The roller body 10 rotates in cooperation with the roller one 3, and it is set to press the fiber material and the polymer melt film into one.

[0045] The melt film conveying device two includes a screw extruder 8, a forming roller two 9 and a roller two 7 pressed together with the forming roller two 9, and the roller two 7 rotates in cooperation with the rol...

Embodiment 2

[0051] The method for using the continuous production system of the laminated biomass composite material of the present embodiment comprises the following steps:

[0052] S1. Put the polymer material A in the screw extruder 1, extrude the polymer material A on the forming roller 1 through melting and plasticizing, press the forming roller 2 and the roller 3, and form the forming roller 2 Heating to 30~300°C with roller one 3, pressing the polymer material A to form a polymer melt film A4 in a molten state;

[0053] S2. At the same time, add the biomass fiber material to the biomass fiber material conveying device, drive the conveying device through the roller body 10, open the three-dimensional vibrator 14 and the dispersion roller 13 below the conveying device, and convey the biomass fiber material to the roller body 10 Between the roller 10 and the roller 3, there is a certain pressure and action angle between the roller body 10 and the roller 3, so that the biomass fiber ma...

Abstract

The invention discloses a continuous production system of a laminated biomass composite material. The continuous production system comprises a first melt film forming device and a fiber material conveying device; the first melt film forming device comprises a first forming roller and a first roller which is in press fit with the first forming roller; the fiber material conveying device comprises aconveyor, a vibration device and a conveying device provided with roller bodies, and the vibration device is arranged below the conveying device; and the roller bodies cooperates with the first roller to rotate to press a fiber material and a polymer melt film into a whole. According to the system, the problems of poor fluidity, tendency in overheating, releasing of a large amount of gas in the production process and uneven dispersion in the production process of the composite material carried out after the fiber and the plastic are blended are effectively solved, so that the production efficiency of the laminated biomass composite material is improved, and the laminated biomass composite material is easy to process; and all layers of the materials to be compounded are orderly combined through the continuous production system, the composite materials with different materials and different layers can be compounded according to actual production requirements, so that the system is suitable for processing of the different materials, and the practicability is high.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a continuous production system of laminated biomass composite materials and a method for using the same. Background technique [0002] Wood-plastic composites (Wood-Plastic Composites, WPC) is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride, etc. Wood flour, rice husk, straw and other waste plant biomass fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce boards or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. The board formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called extruded wood-plastic composite board. [0003] Biomass composite materials can not only give full...
