Each of the four color group units comprises a set of printing cylinder groups (10) located at a middle part, two sets of ink supply systems (20) located in one-to-one correspondence at left and right sides of the printing cylinder groups, and two sets of water supply systems (30) located in one-to-one correspondence at lower left and lower right sides of the printing cylinder groups, wherein the arrangement distance between adjacent color group units is 0.5-0.7 meters, so that the total height of the printing machine is not greater than 2.8 meters. Such a newspaper printing machine may reduce the expansion value of paper tape by half and meet 0.1mm as specified by the national standard, which improves the printing quality and may significantly reduce the amount of waste when starting to print.

Description

A compact newspaper printing machine

Technical field

The invention relates to a compact newspaper printing machine.

Background technique

The traditional newspaper printing machine is generally composed of four color group units, and the paper tape passes through the four color group units from bottom to top to complete the double-sided four-color printing of the paper tape.

Figure 1 shows the structure of a typical newspaper printer. Each color group unit is composed of a printing cylinder 10 in the middle, an ink supply system 20 on both sides, and a water supply system 30. The distance between adjacent color group units is about 1 meter, and the total height H of the entire printing press is 4.5 Meters.

When the existing printing machine is working, the paper tape will absorb the moisture on the printing plate after printing through each color unit, and due to the influence of water, the paper tape will have a "fan-shaped expansion" phenomenon in the width direction. This "fan-shaped expansion" has the most obvious effect on the accuracy of overprinting. When the expansion value is greater than the precision of 0.1mm specified by the national standard, the paper tape enters the next color unit unit and causes overprinting. If certain elimination measures are not taken, it will greatly affect the printing quality of the color newsletter. In order to solve this problem, anti-expansion devices are usually used to solve this problem, that is, the paper tape enters the second color group unit, the paper tape enters the third color group unit, and the paper tape enters the fourth One such anti-expansion device 40 is installed on the path of the color unit, which makes the structure of the printing machine complicated and highly difficult to compress. In addition, the use of this anti-expansion device requires manual adjustment, which is not only slow but also unstable. If it is not adjusted when printing is started, a large amount of printed sheets will be wasted, which is extremely unsuitable for the current production needs of small batches and many varieties.

Summary of the invention

The purpose of the present invention is to overcome the shortcomings of the prior art and provide a compact newspaper printing machine, which can reduce the expansion value of the paper tape by half, meet the national standard of 0.1mm, improve the printing quality, and can obviously Reduce the amount of scrap at the beginning of printing.

The object of the present invention is achieved as follows: a compact newspaper printing press, including four color group units installed between the operating side wall panel and the starting side wall panel of the printing machine and arranged from bottom to top; four colors The group unit includes a set of printing cylinders located in the middle, two sets of ink supply systems corresponding to the left and right sides of the printing cylinders, and two sets of water supply located on the lower left and lower right sides of the printing cylinders The system, in which the arrangement distance between adjacent color group units is 0.5 to 0.7 meters, so that the total height of the printing press is not greater than 2.8 meters.

In the above-mentioned compact newspaper printing machine, the operation side wall panel and the starting side wall panel are respectively divided into a left wall panel, a middle wall panel and a right wall panel; wherein,

The middle wall panel is fixed to the middle of the top surface of the wall panel base, and a left slide rail and a right slide rail are installed in a one-to-one correspondence with the left side of the top surface and the right side of the top surface of the wall panel base; the left wall panel and the right side Each wall panel is installed on the left slide rail and the right slide rail in a one-to-one correspondence through the chute installed on the bottom surface, so that the left wall panel and the right wall panel can be laterally installed on the wall panel base;

The printing cylinder group of the four color group units and the two water supply systems are installed on the central wall panel, and the two ink supply systems of the four color group units are installed on the left wall panel and the right wall panel in a one-to-one correspondence on.

In the above-mentioned compact newspaper printer, a clutch mechanism is installed between the left wall panel and the middle wall panel and between the right wall panel and the middle wall panel.

The above-mentioned compact newspaper printing machine, wherein each locking is provided between the left wall panel and the left side of the top surface of the wall panel base and between the right wall panel and the right side of the top surface of the wall panel base mechanism.

The compact newspaper printer of the present invention has the following characteristics:

1. Shorten the arrangement distance between adjacent color group units to 0.5 to 0.7 meters, so that the value of the expansion of the paper tape when printing after one color group unit enters the next color group unit is reduced by half, meeting national standards The specified 0.1mm, so there is no need to install an anti-expansion device, saving time and effort, improving printing quality, and significantly reducing the amount of waste when starting printing;

2. Because the arrangement distance between adjacent color group units is shortened to 0.5 to 0.7 meters, the height of the printing press is reduced from 4.5 meters to no more than 2.8 meters. It can reduce the height of the user's plant, save the cost of building the plant and air conditioning, and the cost of VOC treatment. It can also eliminate the two-layer footboard and reduce the risk of personnel operation;

3. In order to facilitate the maintenance and maintenance of the printing press, the printing press wall panel is divided into left, center and right parts. The central wall panel is installed with a printing drum set and two water supply systems. The left wall panel and the right wall panel are each installed with a Set of ink supply system, a clutch mechanism and a locking mechanism are provided between the left and right wall panels and the middle wall panel, so that the operator can open the left wall panel and the right wall panel to enter printing when performing post-print maintenance The interior of the machine.
