Double-positioning cold-ironing system

Abstract

The invention provides a double-positioning cold-ironing system which comprises a displacement roller driven by a motor, a compression roller of the displacement roller, an electric eye A reading a cold-ironing film cursor and an electric eye B reading a presswork cursor. The electric A and the electric B are respectively communicated with a computer control unit and respectively transmit the read cursor signals to the computer control unit. The computer control unit controls the motor and drives the displacement roller to move ahead or backward according to the difference value between the two cursor signals so that fine tuning and calibration can be conducted. The double-positioning cold-ironing system can use the cold-ironing film repeatedly for many times and transfer the whole trademarks like laser patterns designed in advance to the specified fixed position on the presswork so that positioning cold ironing can be realized.

Description

technical field [0001] The invention belongs to the technical field of cold foil printing, and specifically relates to a positioning cold foiling system for overlapping and registering each complete laser pattern (the first pattern) on the cold foil film and each glue pattern (the second pattern) on the printed matter , because the two patterns are overlapped and registered, so it belongs to the double positioning cold perm system. Background technique [0002] The current cold foil system is a single-position cold foil system, which can only transfer the metal coating (incomplete pattern) on the cold foil film to the designated position on the printed matter. Such as Figure 5 As shown, it includes an unwinding unit (1), a winding unit (2) and a computer control unit (3). The cold film (4) is sent out from the unwinding unit (1), wound around the roller (5) and printed on the printed matter. The local glue pattern (20) on (6) is bonded → UV light curing → peeling off → tra...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of the current single-position cold stamping system are: 1. The cold stamping film can only be used once, and the metal coating between two adjacent hot stamping positions on the cold stamping film has not been fully utilized and can only be discarded together with the used cold stamping film waste. throw away

2. It is not possible to transfer trademarks such as laser patterns (14) and other complete fixed positions designed in advance to the designated positions on the printed matter

[0004] Two patent applications including Chinese patent CN201151231Y "Multi-color group positioning cold foil transfer printing machine" and Chinese patent CN101480867A "Method for realizing multi-color group positioning cold foil transfer printing" are documents submitted by the same applicant. These two patent application documents, Only the preliminary idea of ​​the dual-positioning cold ironing system was proposed, neither a specific practical technical solution nor the working principle of the dual-positioning system was proposed, and those skilled in the art could not manufacture its "multi-color group positioning system" based on its application documents. Cold Foil Transfer Printing Machine”

The applicant once ordered the "multi-color group positioning cold stamping transfer printing machine (CN201151231Y)" from the applicant several years ago, but the applicant himself has not been able to produce an available "multi-color group positioning machine" so far.
