Problems solved by technology

There are still some problems in the design of the current printing machine. For example, when the paper enters the printing machine, the current printing machine does not remove dust from the paper, which will affect the printing of the paper. After the printing is finished, it is air-dried, which will cause the dye on the paper to be easily blurred, which cannot meet the user's requirements for the printing device.
[0003] In view of the above problems, the patent with the existing patent notification number CN207772627U discloses a printing device, which uses electrostatic adsorption to achieve dust removal by setting an electrostatic adsorption dust removal mechanism in contact with the cardboard at the inlet and outlet. , but it is easy to cause a thick layer of dust to be absorbed on the surface of the roller used for vacuuming, so that the diameter of the roller will cause irreparable damage to the paper

Embodiment 1

[0032] see Figure 1-4 , in an embodiment of the present invention, a green environmental protection printing device includes a printing body 1 and a set of guide rollers 101 arranged at its feed end and discharge end for guiding paper, the feed end of the print body 1 There is a printing roller 4 for printing on the surface of the paper, and the inside of the printing body 1 on the right side of the printing roller 4 is provided with an ultraviolet drying lamp 6 for drying ink marks on the surface of the paper after printing, and the inside of the printing body 1 is There is also a cleaning brush 3 located between the left guide roller group 101 and the printing roller 4, which is used to clean the surface of the paper, and the dust on the surface of the paper is continuously disturbed by the rotation of the roller on the cleaning brush 3. , the printing body 1 is also provided with a dust removal and adsorption assembly 2 for preventing the waste gas generated by printing fr...

Embodiment 2

[0039] The difference from Example 1 is: In order to avoid the influence of the temperature rise of the paper on the later coating during printing and drying (higher paper temperature will make the coating layer not easy to shape), the coating calender assembly 8 The inside of the printing body 1 on the left is provided with a set of cooling rollers 61 for cooling the paper. The set of cooling rollers 61 includes a cooling cylinder 610 in contact with the surface of the paper. The inside of the cooling cylinder 610 is provided with a filling layer for absorbing the heat of the paper. 613, the filling layer 613 is preferably water with a larger specific heat capacity. The filling layer 613 is connected to the metal layer 612 wrapped on the outside of the cooling cylinder 610 for direct contact with the paper through several metal heat conducting rods 611. The heat is absorbed and transmitted to the filling layer 613. The end of the cooling cylinder 610 is provided with a semicon...

Embodiment 3

[0041] The difference from Example 1 is that in order to facilitate the control of the printing quality, the inside of the printing body 1 is also provided with a screening assembly for screening printing paper, and the screening assembly includes printing rollers 4 and ultraviolet drying The first camera 5 between the lamps 6 and the second camera 7 arranged on the right side of the coating calender assembly 8 obtain the product quality after printing on the paper through the first camera 5, and obtain the coating quality on the paper through the second camera 7. The quality of the product after the protective layer is convenient for later judgment of the wrong position and helps to determine the maintenance position. The screening assembly also includes a marking assembly 91 arranged at the second camera 7, and the marking assembly 91 includes a telescopic cylinder and a setting The end of the telescopic cylinder is used to stamp the marking head on the surface of the paper. ...

Abstract

The invention discloses an environment-friendly printing device. The device comprises a printing body and guide roller sets arranged at the feeding end and the discharging end of the printing body respectively and used for guiding paper, wherein printing rollers used for printing on the surface of paper are arranged at the feeding end of the printing body, ultraviolet drying lamps used for drying ink marks on the surface of printed paper are arranged in the printing body and on the right side of the printing rollers, clearing brushes used for clearing ash on the surface of paper and located between the left guide roller set and the printing rollers are further arranged in the printing body, and a dust absorbing assembly used for preventing waste gas produced during printing from overflowing is further arranged on the printing body. The environment-friendly printing device is improved to overcome defects of existing devices; the dust removal manner is optimized and dust is removed in a dust transfer manner, so paper cannot be damaged with increase of filtering time and flow of air in the printing body can also be facilitated, which contributes to drying of ink marks.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a green printing device. Background technique [0002] The printing device is a device that transfers the ink of the graphic on the printing plate to the paper. Its working principle is to first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink manually or by the printing machine. It is applied to the place where there are text and images on the printing plate, and then directly or indirectly transferred to paper or other substrates, so as to reproduce the same printed matter as the printing plate. There are still some problems in the design of the current printing machine. For example, when the paper enters the printing machine, the current printing machine does not remove dust from the paper, which will affect the printing of the paper. Air-drying is carried out after printing, which causes the dy...
