Automatic edge trimming machine for pressing plate

Abstract

The invention discloses an automatic edge trimming machine for a pressing plate. The automatic edge trimming machine comprises a rack, a transverse side processing mechanism, a longitudinal side processing mechanism, a loading mechanism, a pushing plate mechanism, a stacking mechanism and a PLC, wherein the loading mechanism, the transverse side processing mechanism, the pushing plate mechanism, the longitudinal side processing mechanism and the stacking mechanism are sequentially arranged on the bracket; each of the transverse side processing mechanism and the longitudinal side processing mechanism is equipped with an edge sawing mechanism, a waste mechanism and an edge supplementing mechanism; and the PLC is arranged on the rack and is electrically connected with each mechanism. The automatic edge trimming machine realizes automatic production for edge sawing and edge supplementing of the pressing plate, and realizes automatic loading, edge sawing, waste collecting, edge supplementing, pushing plate edge-changing and stacking; and the edge supplementing mechanism of the device presses a filling material into a gap of the pressing plate through an injection way, the edge-supplemented plate is flat in appearance, and the filling material is not liable to drop, is good in waterproof performance and is long in service life. The edge-sawing edge-supplementing mechanism is high indegree of automation, is good in processing quality, and improves edge trimming efficiency of the pressing plate.

Description

technical field [0001] The invention relates to plate processing equipment, in particular to an automatic trimming machine for pressed plates. 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. Because it has no sawdust, every 2.2-2.5 cubic meters of logs can produce 1 cubic ...

AI Technical Summary

Problems solved by technology

[0004] Since the plywood is made of dried thin boards, the dried thin boards usually have bending, missing corners, and damage. After pressing into a plywood board, holes will appear after sawing and trimming, which is not conducive to subsequent processing. Moisture is easy to infiltrate from the pores and cause the phenomenon of edge frying, and the gaps also affect the appearance of the entire board, so it is extremely important to perform edge repairing; the existing method is to scrape and repair the entire stack of neatly stacked boards, dry them After polishing, the process is complicated, usually requires manual processing, the work efficiency is slow, and the filled gray layer (putty powder) is easy to fall off during transportation or handling, which affects product quality

Therefore, the existing processing equipment cannot meet the automatic production requirements of high-quality plywood
