One-step molded V-shaped plate forming technology and molded V-shaped plate

Abstract

The invention relates to a composite door filling core plate manufacture technology and a filling core plate and particularly relates to a one-step molded V-shaped plate forming technology and a molded V-shaped plate. The forming technology comprises the steps of step one, collecting leftover materials produced during production of a composite door, putting the leftover materials in a pulverizer to be pulverized, exposing and drying the pulverized materials, sending the dried pulverized materials to a glue blender for glue blending, laying the pulverized materials after glue blending on a plate holding trolley on a conveying belt in a fixed thickness, and sending the pulverized materials into a cold press by the plate holding trolley to be pre-pressed into pulverized material slabs; step two, conveying the pulverized material slabs in the first step to molds with V-shaped grooves of the hot press through the conveying belt to be molded into V-shaped plates through hot pressing. One section of a plate body of the molded V-shaped plate is in a directly connected line shape, the other section is in a regular wave shape, and the regular wave shaped section is formed by integral connection of a plurality of identical V-shaped sections. By means of the forming technology and the molded V-shaped plate, the energy consumption is reduced, and production costs are reduced.

Description

technical field [0001] The invention relates to a manufacturing process of a composite door filling core board and a filling core board, in particular to a molding V-shaped board process and a molded V-shaped board for reducing energy consumption and production cost. Background technique [0002] The solid wood composite door (that is, the hollow door) on the existing market is made of two panels with a filling core board between the two panels. The existing filling core board generally adopts bridge cavity mechanics hollow board, honeycomb cardboard door core, Filling materials such as strips and composite board strips. [0003] In the process of use, the mechanical properties of the composite door using the honeycomb cardboard door core are poor; the mechanical properties of the bridge cavity mechanical hollow plate are strong, but its manufacturing cost is high; it is filled with solid wood strips and composite board wood strips. If the cavity is filled, the energy consum...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the prior art infill core board consumes a lot of energy and has high manufacturing cost; finding a kind of infill board with low energy consumption and strong mechanical properties has always been a technical problem for solid wood composite doors
