Device for manufacturing bicolor co-extruded plastic-wood floor

Abstract

The invention discloses a device for manufacturing a bicolor co-extruded plastic-wood floor. The device comprises a forming mold and two co-extruders connected to the forming mold. The forming mold comprises a discharging outlet and four extrusion tube sets which are in the same shape and are connected to the discharging outlet. Two of the extrusion tube sets are arranged on the upper portion of the discharging outlet, the other two extrusion tube sets are arranged on the lower portion of the discharging outlet, and the extrusion tube sets arranged on the upper portion and the lower portion ofthe discharging outlet are in mirror symmetry with the discharging outlet as the axis; the extrusion tube sets arranged on the upper portion or the lower portion of the discharging outlet are in mirror symmetry with the central line perpendicular to the length direction of the discharging outlet as the axis, and the two extrusion tube sets located on the upper portion or the lower portion of thedischarging outlet are connected through a pipeline; and each extrusion tube set comprises two Y-shaped extrusion tubes, wherein one ends of the two extrusion tubes are connected mutually, and the other two ends of each extrusion tube are connected to the discharging outlet. The device for manufacturing the bicolor co-extruded plastic-wood floor is reasonable in design, the upper surface and the lower surface are extruded towards the discharging outlet simultaneously, the extrusion speeds of the extruders are the same due to the same paths of the extrusion tube sets, and the bicolor co-extruded plastic-wood floor with different colors of the upper and lower surfaces is formed.

Description

technical field [0001] The invention belongs to the field of plastic-wood composite materials, and in particular relates to a device for making two-color co-extruded plastic-wood floors. Background technique [0002] Wood-plastic flooring is a new type of environmentally friendly plastic-wood composite material product. The wood phenol produced in the production of medium and high-density fiberboards is added to recycled plastics to make plastic-wood composite materials through granulation equipment, and then extruded into production groups. Made of plastic wood flooring. The main material of plastic wood flooring is PE and wood powder or bamboo powder. After adding additives and mixing at high speed, it is granulated, and then extruded by an extruder to form a material. This type of floor can be used in gardens, villas, etc. Outdoor deck. The traditional plastic-wood floor is the same color, and the visual effect is not rich enough as an outdoor building. If there are mul...

AI Technical Summary

Problems solved by technology

The traditional plastic-wood floor is the same color, and the visual effect is not rich enough as an outdoor building. If there are multiple colors, it is necessary to use a variety of plastic-wood floors. The production cost is high, and it often causes a certain color in the actual laying process. Oversupply, resulting in low utilization rate and increased manufacturer's cost

[0003] At present, in order to solve the problem of single color and low utilization rate of plastic wood flooring, some manufacturers adopt the structure of layering the upper and lower surface colors of plastic wood flooring. The color of the upper and lower surfaces of the wooden floor, thus forming a floor of two or more colors

However, this type of two-color floor has high requirements in production. The existing method is generally to extrude the two-color boards from the extruder first and then glue them. The glue pollutes a lot, and the strength of the floor itself is also low.
