Environment-friendly five-color printing press

Abstract

The invention discloses an environment-friendly five-color printing press and relates to the technical field of printing equipment. According to the technical scheme, the environment-friendly five-color printing press is characterized in that the printing press comprises a machine body and five printing mechanisms located in the machine body in sequence in the paper conveying direction; a conveying inlet is formed in one end of the machine body, and a conveying outlet is formed in the other end of the machine body; each printing mechanism comprises an ink groove, an ink feeding roll, a coatingroll and a pressure roll, and the ink feeding roll, the coating roll and the pressure roll are rotationally connected and abut against one another; the machine body is connected with a drying mechanism and an air purifying mechanism; the air purifying mechanism comprises a tank which is internally provided with at least two purifying chambers communicating with one another; and every two adjacentpurifying chambers communicate through a communication pipe, wherein one purifying chamber communicates with the interior of the machine body through a main air inlet pipe, and the other purifying chamber is provided with an air outlet pipe. By means of the environment-friendly five-color printing press, the problem that a current printing press emits irritant gas towards a working site in the printing process to affect the health is solved, air inside the printing press can be treated, and air at the working site is kept fresh.

Description

technical field [0001] The invention relates to the technical field of printing equipment, more specifically, it relates to an environment-friendly five-color printing machine. Background technique [0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms such as plate loading, ink application, embossing, and paper feeding. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Printing onto paper or other substrate, thereby replicating the same print as the printing plate. According to different printing colors, printing machines include three-color printing machines, four-color printing machines and five-color printing machines. [0003] The prior art refers to the C...

Problems solved by technology

[0005] The above-mentioned printing machine has dust removal effect when printing with water-based multifunctional printing ink, but it has the following disadvantages: the printing ink needs to be dried and baked after printing, and the paper bag or plastic film is exposed to the air during the transmission process. Organic matter will volatilize in the air, leading to an increase in the content of toxic substances in the workplace and affecting the occupational health of workers
