Description

PRESS PRINTING METHOD AND MACHINE USING THE METHOD}

The present invention relates to a pressure printing method and an apparatus thereof, and more particularly, to a pressure printing method and apparatus for compressing and forming a printing pattern by imprinting various types of pictures and characters on paper while applying heat and pressure.

The general printing method is to combine a plate engraved with a variety of pictures and letters on the printing roller of the printing press, and the ink is printed on the sheet of the plate surface. As such, the conventional printing method requires the use of ink, which not only has a problem that the printing operation and management are cumbersome and complicated depending on the handling of the ink, but also increases the printing cost. There was a difficult issue.

The present invention has been made in order to solve the above-mentioned conventional defects and problems, and provides a pressure printing method to compress the printing pattern by imprinting the printed pattern by applying heat and pressure to the stamps embossed with various pictures and characters on the paper. The purpose is to.

Another object of the present invention is to pressurize printing by heat injection printing by the lower heating compression roller and the upper contact roller formed on the surface by injecting steam to the paper by steam injection means while transferring the paper from the feed roll to the take-up roll. It is for providing a device.

Still another object of the present invention is to provide a crimped pattern printing paper which is imprinted with various figures and letters imprinted on a paper, and the print pattern is formed by pressing.

In order to achieve the above object, the pressure printing method of the present invention comprises the steps of conveying a paper unwinding from a feed roll along a predetermined path while winding it on a take-up roll, and heating the lower portion of the paper on which a stamping part is formed on the surface and heated by a heater. It comprises a step of heat compression printing while transferring between the compression roller and the upper contact roller, and spraying steam to the paper flowing into the heat compression roller and the contact roller.

The pressure printing apparatus further includes a supply roll for supplying paper, a winding roll for winding the paper, a plurality of guide rolls for guiding the conveyance of the paper, and a heating compression roller having a stamp portion formed on the surface and heated by a heater. Heat compression means for printing and heat-compressing printing with contact rollers disposed thereon and conveying the paper therebetween; and steam injection for spraying and wetting steam onto paper to be supplied and placed in front of the heat compression means. It comprises a means.

In addition, it provides a crimped pattern printing paper consisting of stamps embossed with various figures and characters stamped on the paper is formed by pressing the print pattern.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail as follows.

1 to 4 is a view of the present invention, Figure 1 is a schematic configuration diagram of the pressure printing device of the present invention, Figure 2 is a perspective view of the printing roller, Figure 3 is enlarged the printing pattern of the printing roller 4 is a plan view of the printing paper according to the present invention, and FIG. 5 is a partially enlarged cross-sectional view of the printing paper.

As shown in the drawing, the heat compression printing apparatus according to the present invention provides a feed roll 2 for supplying the paper 1, a winding roll 3 for winding the paper 1, and transfer of the paper 1. A plurality of guide rollers 4 for guiding and a heating compression roller 5 having a stamping portion 8 formed on the surface and heated by a heater are disposed below, and the contact rollers 6 are disposed on the upper side of the paper ( 1) heating compression means 9 for heat compression printing while transferring between them, and steam injection means for spraying and soaking steam onto the paper 1 to be supplied and disposed at the front of the heat compression means 9; It consists of (10).

The heating compression roller (5) is formed in a cylindrical shape with a metal material such as stainless steel and copper alloy, and the heating compression roller (5) has a stamping portion (8) such as a mark, a sign, a character to be printed, and a surface thereof with an embossed surface (8a). The printing plate which is formed integrally with or in which the stamping part 8 is formed is wound around and fixed to the outer peripheral surface. This stamping part 8 may be formed as an intaglio 8c as a part thereof. Then, the heater for heating the heating compression roller 5 is coupled to the inside of the heating compression roller (5).

A high strength pulp extrusion roller or the like may be used for the contact roller 6, for example, the pulp compression roller is formed by compressing a paper pulp at a high pressure (800 kg).

In addition, the heating compression roller (5) and the contact roller (6) is assembled so as to adjust the gap therebetween as necessary, this gap adjusting means is to lift the upper contact roller (6) by hydraulic or pneumatic cylinder to reduce the gap. It can be configured to adjust.
