Edge-cutting-free magnesite board edge folding tool

Abstract

The invention discloses an edge-cutting-free magnesite board edge folding tool. The edge-cutting-free magnesite board edge folding tool comprises edge folding roller sets, the edge folding roller setsare composed of a plurality of edge folding rollers, the edge folding rollers are provided with inclined surfaces with flanging folded edges, the inclined surfaces are used for folding edges of the surface layer of an edge-cutting-free magnesite board, the edge folding rollers are hinged to connecting rods, the connecting rods are fixed on a mounting panel of a machine frame through fasteners, included angles between the inclined surfaces of the edge folding rollers and the horizontal planes are gradually reduced from large to small, and the included angles between the inclined surfaces of the edge folding rollers and the horizontal planes are divided into an obtuse angle, a right angle and an acute angle. The edge-cutting-free magnesite board edge folding tool of the structure is high inedge folding efficiency, and is suitable for line production of production of the edge-cutting-free magnesite board.

Description

Technical field [0001] The invention relates to a hemming tool, in particular to a cutting-free edge hemming tool for magnesite plates, which belongs to the technical field of magnesite plate production. Background technique [0002] Patent Application No. 201720741645X describes an edge-free magnesite board, which is composed of a surface layer, a bottom layer and an adhesion layer. The two sides of the surface layer are respectively formed with folds inward, and the folds are turned 180 degrees inward. The bottom cover is on two folds, and the folds and the bottom layer form a section of overlapping overlap area. In the prior art, the folding process is performed manually, and the folds need to be manually turned over, and then the bottom cover In the hemming, this kind of operation method has low efficiency, is not suitable for flow operation, and cannot be used for mass production of edge-free magnesite plates. Summary of the invention [0003] In view of the above-mentioned ...

[0002] Patent application number 201720741645X describes a kind of edge-free magnesite board, which is composed of a surface layer, a bottom layer and an adhesion layer. The two sides of the surface layer are respectively inwardly formed with folded edges, and the folded edges are turned 180 degrees inward. The bottom layer is covered on the two folded edges, and the folded edges and the bottom layer form a section of overlapping area. In the prior art, the folding process is performed manually, and the folded edges need to be manually turned over, and then the bottom layer is covered. On the edge folding, this kind of operation method is inefficient, not suitable for assembly line operation, and cannot be applied to the mass production of edge-free magnesite boards
