Description

Duplex Color Printing Rototype Printing Machine Structure

The present invention relates to a double-sided color printing roto type printing machine structure, and more particularly, while the tension of the paper passing through the printing unit is kept constant, the printing pin position of each unit is consistent, so that the print quality is good and the incidence of paper loss is 30. It can be lowered from% to 50%, it is small in volume, can be installed in a small space by occupying a small installation area, and can produce a wide-area printing machine capable of producing 1.5 times as compared to conventional printing machines at the same production cost. It's about structure.

In general, a rotatable printing machine is a device for printing printed matter, such as newspapers, magazines, pamphlets at high speed, and is a printing device of printing a printed object by pressing a cylindrical printed body.

1 and 2 illustrate a conventional rotatable color printing press, and FIG. 1 is a view showing a double-sided color tower rotary press for printing a newspaper mainly at high speed, and FIG. 2 is a high speed printing of a printed matter such as a magazine or a brochure. A diagram showing a commercial double-sided color printing machine for printing.

Referring to Figures 1 and 2, the conventional rotatable color printing machine is composed of first to fourth printing units (1 to 4) for printing letters or pictures of different colors on both sides of the printing paper, each printing Units 1 to 4 are provided with pairs of

plate cylinders

5 and 6 and

blanket cylinders

7 and 8 facing each other for printing different sides, and the butt cylinders 7 which are opposed to each other. Between 8), printing paper passes through line contact.

With this configuration, the conventional rototype printing machine has different colors on both sides of the printing paper 9 when the printing paper 9 passes between the

blanket cylinders

7 and 8 of the respective printing units 1 to 4. A letter or picture is printed, the first color of which is respectively printed on both sides of the printing paper 9 when the printing paper 9 passes between the pair of

blanket cylinders

7 and 8 of the first printing unit 1. This is printed, and the second color, the third color, and the fourth color are sequentially printed on both sides of the printing paper 9 while passing through the second to fourth printing units 2 to 4 in the same process.

However, the conventional rotatable printing machine has a printing paper that passes through each printing unit while the printing paper passes through the line contact between the Blanket cylinders, so that the printing paper shakes when the speed or tension of the printing paper is fed. This results in the problem that the position of the letters and pictures of a plurality of colors printed on the printing paper does not match as the color pins are separated, which causes the print content to be out of focus and the printing is not made accurately, resulting in a high incidence of damage. There is a problem.

In addition, since the conventional rototype printing machine is composed of four printing units, there is a problem in that the structure is complicated and the manufacturing and installation costs are increased due to a large occupying the installation area.

The present invention has been made to solve the above problems, the printing paper passing through the printing unit is in contact with the surface of the Blanket cylinder to be printed, the tension of the printing paper is kept constant, the printing pin of each unit Due to the consistent position, it is possible to reduce 30% to 50% of paper loss compared to conventional printing presses, which is equivalent to the purchase price of the machine when used for the life of a rotary press (about 30 years). It is an object of the present invention to provide a color printing rototype printing press structure.

In addition, by forming a rotatable color printing machine capable of double-sided color printing by using two printing units, the structure of the rotatable printing machine can be simplified, and the volume of the rotatable printing machine can be reduced, making it easy to install in a small space, and high speed. The purpose of the present invention is to provide a double-sided color printing roto type printing press structure.

In addition, the biggest point of the present invention is that the type of printing machine has developed from simple text printing to high speed printing machine to high speed printing machine to high speed printing machine in accordance with the increase in the number of prints with the increase of the current population and the rapid delivery of high quality information as the information volume increases. Now, we have developed a high-speed, high-quality color printing machine that can print about 60,000 copies per hour, and the printing machine structure of this patent application can produce 1.5 times prints with similar production cost compared to the current high-speed high-end printing machine. The purpose is to provide a double-sided color printing roto type printing press structure.

The present invention for achieving the above object is, in the rototype printing machine for printing a printed matter, the first printing portion for printing the first color on one surface of the printing paper and the interval along the outer peripheral surface of the first printing portion A first printing unit having a second printing unit, a third printing unit, and a fourth printing unit which are in contact with each other and sequentially print a first color, a second color, and a third color on the other surface of the printing paper; A fifth printing unit for printing a fourth color on the other surface of the printing paper that has passed through the first printing unit, and a second color is in contact with each other at intervals along the outer circumferential surface of the fifth printing unit, respectively; And a second printing unit comprising a sixth printing portion, a seventh printing portion, and an eighth printing portion, which sequentially print the third color and the fourth color.

In addition, each of the first to eighth printing portion, the Blanket cylinder is in contact with the printing paper, and prints the color on the printing paper; And a plate cylinder in contact with the blanket cylinder and supplying ink to the blanket cylinder.

In addition, a blanket cylinder of the second to fourth printing parts is in contact with the blanket cylinder of the first printing part at intervals along the outer circumferential surface, respectively, and the blanket cylinder of the first printing part and the second to fourth printing parts are contacted. The printing paper passes between the negative blanket cylinders, and the printing of the first color, the second color, and the third color is performed on one surface and the other surface of the printing paper.

In addition, a blanket cylinder of the sixth to eighth print parts is in contact with a blanket cylinder of the fifth print part at intervals along an outer circumferential surface, and a blanket cylinder of the fifth print part and the sixth to eighth prints are respectively contacted. The printing paper passes between the negative blanket cylinders to print the second color, the third color, and the fourth color on the other side of the printing paper and the fourth color.

In addition, between the first printing unit and the second printing unit is characterized in that it further comprises a guide roller for guiding and adjusting the tension of the printing paper.

As described above, the double-sided color printing rotatable printing machine structure according to the present invention, while the tension of the paper passing through the printing unit is kept constant, the position of the printing pin of each unit is matched to reduce the amount of waste paper generated by 30% to 50%. Unlike conventional rotary presses that consist of a large number of existing printing units, they consist of only two printing units, resulting in low machine manufacturing costs, installation in a small area, and high-speed printing and wide presses. It is possible to produce a printing press that can be increased by 1.5 times as much as the production cost compared to the existing printing machine.
