Embodiment 1

[0031] A method for laminating and printing metal sheets, comprising the steps of:

[0032] (1) Pre-lamination: Preheat the metal sheet to 80-120°C, and at the same time, bring static electricity opposite to that of the metal sheet to the surface of the printing film, so that the printing film can cooperate with the pressing action of the pressure roller through electrostatic adsorption Paste on the surface of the preheated metal sheet to form a pre-laminated metal sheet;

[0033] (2) Printing: Printing is carried out on the surface of the printing film of the pre-laminated metal sheet, and the printing quality is checked online after the printing process, and the unqualified substrates are immediately marked for subsequent identification;

[0034] (3) High-temperature fusion: According to the printed pattern detection results, the laminated metal sheet is selectively heated at high temperature, and a high-frequency electromagnetic induction heater is used to heat the laminate...

Embodiment 2

[0040] A method for stamping a laminated sheet metal, comprising the steps of:

[0041](1) Pre-lamination: preheat the metal sheet to 80-120°C, and at the same time bring static electricity opposite to that of the metal sheet on the surface of the film, so that the film can be pressed and pasted by the pressure roller through electrostatic adsorption. The surface of the preheated metal sheet forms a pre-coated metal sheet;

[0042] (2) Die-cut blank: According to the shape of the downstream stamping product, use a die-cutting machine to die-cut the surface of the pre-laminated metal sheet, the edge of the die-cut shape does not exceed the edge of the downstream stamping product shape, and peel off the mold online Film waste in the void around the cut shape;

[0043] (3) High-temperature fusion: use a high-frequency electromagnetic induction heater to heat the pre-laminated metal sheet after die-cutting to make the film high-temperature fusion, and the heating temperature is 1...

Abstract

The invention relates to laminating printing and punching methods of metal plates. The laminating printing method includes the processes of pre-laminating, printing, selective high-temperature fusing, cooling sizing and metal plate recovering. The laminating punching method includes the processes of pre-laminating, die cutting and blank reserving, high-temperature fusing, cooling sizing and punching. According to the printing method, the recovery operation on defective printed metal plates is simplified and can be easily achieved in a simple printing film stripping mode, operation is simple, cost is low, and the recovery cost on the metal plates of an enterprise is lowered. The punching method solves the technical problem that in the prior art, when subsequent punching is conducted on laminated metal plates, film scraps are likely to be formed; die cutting and blank reserving are conducted in advance before the high-temperature fusing step, film waste in gaps of the periphery of a shape to be punched are stripped and removed in advance, and therefore when punching is conducted, the film scraps can be prevented from being generated at a punching notch as long as a punching die corresponds to the die cutting shapes on the laminated metal plates.

Description

technical field [0001] The invention relates to the technique of lamination printing and lamination stamping, in particular to a method for performing lamination printing and lamination stamping on the surface of a metal plate. Background technique [0002] Laminated metal sheet is a kind of metal material with dual characteristics of polymer resin film and metal sheet with excellent deep drawing resistance, wear resistance, corrosion resistance and decoration. This feature determines that the film-coated board can use the cold-rolled plate as the base material to be quickly laminated with the overprinted printing film. Therefore, the film-coated board greatly reduces the material cost. The laminated sheet used in the canning industry is made of PET, PVC, VCM or PP film and metal sheet (galvanized sheet, cold-rolled sheet, aluminum sheet, stainless steel sheet). The inner side of traditional metal cans must be painted, and the substances contained in the coating method will...
