A plywood edge repairing machine and its automatic edge repairing process

Abstract

The invention discloses a plywood edge repairing machine and its automatic edge repairing process, comprising a putty extruding mechanism, a board edge scraping putty mechanism and a board surface putty removal mechanism, the putty extruding mechanism, a board edge scraping mechanism and a board surface putty The removal mechanism is arranged sequentially from upstream to downstream along the plywood conveying direction. When in use, the plywood is transported on the conveyor belt, and the putty extruding mechanism squeezes the putty in the hopper to the edge of the plywood board being conveyed through the putty outlet; as the plywood moves, the putty scraping mechanism scrapes the edge of the plywood board Putty is applied to fill the gaps on the edge of the board; at the same time, the putty removal mechanism on the board surface scrapes off the putty overflowing from the edge of the board to the board surfaces on both sides. Since the plywood is still conveyed on the conveyor belt during edge repairing, the automatic filling of holes in the edge of the plywood during the conveying process can be realized, which reduces labor costs and improves the efficiency of edge repairing of the plywood.

Description

technical field [0001] The invention relates to the field of plywood production equipment, in particular to a plywood edge repairing machine and an automatic edge repairing process thereof. Background technique [0002] Plywood, also known as plywood and thin core board, is one of the commonly used materials for furniture and is a kind of wood-based panel. A group of veneers are usually glued together according to the wood grain direction of adjacent layers perpendicular to each other. Usually, the surface board and inner layer board are symmetrically arranged on both sides of the center layer or core. Plywood not only has all the advantages of natural wood, such as light bulk density, high strength, beautiful texture, insulation, etc., but also can make up for some natural defects of natural wood, such as knots, small format, deformation, and large differences in vertical and horizontal mechanics; Production can rationally utilize logs. In recent years, with the rapid dev...

AI Technical Summary

Problems solved by technology

[0003] Plywood is made of dried veneers, which are usually bent, missing corners, and damaged. After being pressed into plywood, pores will appear after sawing and trimming, which is not conducive to subsequent processing. It is easy to infiltrate from the pores and cause edge explosion, and the gaps also affect the appearance of the whole board, so it is extremely important to fill the edge

The traditional method is that workers manually use putty to repair, the work efficiency is low, and it cannot meet the production requirements of automatic plywood production equipment
