Embodiment 1

[0043] A method for producing claw-type unscrewed caps from pre-printed colored coated iron, comprising the following steps:

[0044] (1) Printing film: use an engraving plate to print the ink on the polyethylene terephthalate film, and keep the printed film at 70°C for 72 hours to completely cure the ink on the film and make it The ink and the film form a firm combination to obtain a printed film; during the printing process of the film, the printing speed is 180 m / min, and the deviation range of the film is controlled within -0.5 ~ 0.5mm;

[0045] (2) Lamination: The film printed in step (1) is attached to the chrome-plated tinplate iron sheet by means of thermal lamination through the lamination roller to obtain the lamination iron; the lamination pressure is 2 tons, and the lamination temperature is 230 ℃, the hardness of the coated roller is adjusted to 60HR;

[0046] (3) Cutting: Cutting according to the pattern size requirements of the printing layout;

[0047] (4) Co...

Embodiment 2

[0054] A method for producing claw-type unscrewed caps from pre-printed colored coated iron, comprising the following steps:

[0055](1) Printing film: use an engraving plate to print the ink on the polyethylene film, and keep the printed film at 80°C for 48 hours to completely cure the ink on the film and form a firm bond between the ink and the film , to obtain the printed film; the film is in the printing process, the printing speed is 100 m / min, and the deviation range of the film is controlled within -0.5 ~ 0.5mm;

[0056] (2) Lamination: The film printed in step (1) is attached to the chrome-plated tinplate iron sheet by means of thermal lamination through the lamination roller to obtain the lamination iron; the lamination pressure is 5 tons, and the lamination temperature is 260 ℃, the hardness of the coated roller is adjusted to 90HR;

[0057] (3) Cutting: Cutting according to the pattern size requirements of the printing layout;

[0058] (4) Covering: coating a laye...

Abstract

The invention discloses a method for producing a claw type unscrewing cover by pre-printing color coated iron, and belongs to the technical field of claw type unscrewing cover manufacturing. The coated iron is adopted as a novel material for manufacturing the unscrewing cover; printing is moved forwards to a production stage of a thin film in the production procedure link, specifically, the film is laminated with an iron sheet after being printed; the iron sheet is cut after being laminated; and then the front face and the back face of the iron sheet are coated with coatings with protection and bonding effects in a rolling mode. The production process of the claw type unscrewing cover includes the steps of film printing, film covering, cutting, finishing, inner coating and cover manufacturing. The method for producing the claw type unscrewing cover by pre-printing the color coated iron provided can shorten the production flow of the claw type unscrewing cover, improve the production efficiency of the claw type unscrewing cover, and improve the printing ink fastness of the coated iron.

Description

technical field [0001] The invention relates to a method for producing claw-type twist-off caps from pre-printed colored coated iron, and belongs to the technical field of claw-type twist-off caps. Background technique [0002] The traditional claw-type twist-off cap is based on tin-plated or chrome-plated tinplate, and the coatings for printing, protection, barrier, and adhesion to the sealing rubber ring are coated on the front and back sides of the tinplate respectively, and the printing coating Printing on the surface to achieve an exquisite appearance. The traditional production process of claw-type twist-off caps includes: tinplate cutting-inner bottom-outer coating-printing-finishing-inner coating-capping, and printing is based on different layouts and colors. Requirements need to be completed through different printing passes. [0003] The traditional claw-type twist-off cap production process has the problems of long production chain, many times of roller coating, ...
