Floating type rotary hot gold stamping method and device

Abstract

A floating type rotary hot gold stamping method includes the steps that discharged foil films are placed between a gold stamping roller and a bottom roller, the foil films are located on printed matter, and gold foil on the foil films is transferred on the printed matter in a covering mode through rolling of the gold stamping roller and the bottom roller. Intermittent feeding and slight dumping of the foil films are achieved through left-right sliding of a gold stamping floating roller, the foil films are tensioned and are not deviated, synchronous gold stamping of the foil films and the printed matter is achieved, and the foil films cannot be wasted or broken. A floating type rotary hot gold stamping device is characterized in that a guide rail slide assembly is arranged on a station, between a gold stamping foil discharging mechanism and the gold stamping roller, on an archway and connected with a power source through an intermediate drive assembly, and the gold stamping floating roller is arranged on the guide rail slide assembly. The floating type rotary hot gold stamping device is especially suitable for conveying thin paper and light paper similar to the foil films, and the printing effect and the printing quality of the printed matter are greatly improved.

Description

technical field [0001] The invention relates to a printing machine, in particular to a circular hot stamping method and a device thereof applied to an intermittent circular hot stamping die-cutting machine. Background technique [0002] At present, the intermittent round hot stamping die-cutting machine consists of unwinding device, front and rear tension control device, deviation correction device, hot stamping device (round pressing), die cutting device, winding device, microcomputer control device and laminating device, It is composed of color mark sensing device, front and rear traction device, waste collection device, frame, etc., among which, hot stamping device is a round pressing method, including archway, bronzing foil release mechanism, front and rear traction roller, bronzing waste collection mechanism, bronzing roller ( The interior is oil heating method), bottom roller, etc., which transfer and cover the foil gold on the foil film to the printed matter (with sel...

AI Technical Summary

Problems solved by technology

Since the printed matter has the action of intermittent feeding and then a little rewinding during the feeding process, and the hot stamping foil release mechanism is always in the state of intermittent film release for the foil film, which is likely to cause waste of the foil film, and even cause the wrong version of the stamping, and The foil film is thinner and lighter, and it is easy to cause the foil film to deviate and tear, which affects the printing effect and printing quality
