Flanging device for flanging machine

Abstract

The invention discloses a flanging device for a flanging machine. The device comprises a flanging disc, wherein a boss is arranged at the center of the flanging disc, and a connecting shaft runs through the center of the boss; rotating blocks are arranged at two ends of the connecting shaft, a rotary connector is arranged in one rotating block, and is provided with a connecting wire; the connecting wire runs through the through hole in the connecting shaft and is connected with an annular wire; the annular wire is positioned outside the connecting shaft, and is connected with a heat wire through a branch wire; an insulation board is arranged on the side, close to the connecting shaft, of the heat wire, and a heat conductive plate is arranged on the side, far from the connecting shaft, of the heat wire; and the side, far from the heat wire, of the heat conductive plate is fixedly connected with one side of the heat conductive plate, and a heat conductive connecting block is fixedly connected with the other side of the heat conductive plate. According to the flanging device, the disc-shaped flanging plate enables the flanging disc to flange a plastic bag along a bent groove, the plastic bag can be flanged more uniformly, and the plastic bag flanging quality can be improved.

Description

technical field [0001] The invention relates to the related technical field of edge folding machines, in particular to an edge folding device of an edge folding machine. Background technique [0002] With the development of social economy, most of the products need to be packaged in plastic packaging boxes. The usual plastic packaging boxes are made by thermoforming the plastic sheet into a concave cavity with the same shape as the product, and the plastic sheet is folded manually. Processing, then put the product into the concave cavity and then insert the cardboard into the folding edge and seal it. In the prior art, the hemming process of the plastic sheet is usually done manually. During the hemming process, the workers use their fingers to press the plastic sheet on the heating wire. Due to the uneven force on the plastic sheet, the edge of the finger is often folded. The effect is obvious, and even the edge of the plastic sheet is deformed due to excessive force, whil...

Problems solved by technology

[0003] The purpose of the present invention is to provide an edge folding device of an edge folding machine to solve the problem that due to the uneven force on the plastic sheet, the effect of the edge folding on the finger press is obvious, and even the edge of the plastic sheet is deformed due to excessive force, while other places are caused by Insufficient force and poor contact with the heating wire lead to the problem that the folding effect is easy to rebound, and the deformation problem of uneven cooling heat
