Printing machine is a mechanical device that presses the ink surface on the media.As one of the equipment with the highest utilization rate in the printing plant, printing machine printing has the advantages of high degree of automation, fast printing speed, and good product quality.The following editor will introduce the principle of the printing machine?What types are there?
Profile
Modern printing machines are generally composed of loading, ink, printing, paper -mocked paper and other institutions.When working at work, the text and images to be printed into prints are printed into a print, packed on the printing machine, and then painted the ink on the printing version of the text and images by artificial or printing machine, then transferred directly or indirectly to toPaper or other printers to copy the same printed materials as the printing version.
Printing surgery was first invented in China. The printed books have appeared in China since the ninth century, and then the printing of Chinese invented in China has been passed on to countries around the world.The invention and development of the printing machine plays an important role in the spread of human civilization and culture.
In 1439, Ge Tengbao in Germany created a wooden convex printing printing machine. Although this vertical spiral hand tide printing machine is simple, it has been used for 300 years.TEIDATE flat convex version printing machine; in 1847, Hoy invented by the United States in invention of a rotary printed machine; in 1900, a six -color rotation printing machine was made; in 1904, Rubel in the United States inventing a plastic version of the printing machine.
Before the 1950s, the traditional convex printing technology occupied its dominant position in the printing industry, and the development of the printing machine was mainly a convex printing printer.However, there are shortcomings of lead alloy convex printing technology, with high labor intensity, long production cycle, and pollution environment.Since the 1960s, the flat -version plastic printing process with short period of cycle and high productivity has begun to rise and developed. Lead alloy convex printing printing has gradually been replaced by the flat version of the printing printing.Soft convex printing, hole printing, electrostatic printing, inkjet printing, etc. have also developed in packaging printing and advertising printing.
The printing machine is divided into a printed version, flat version, concave, and hole version printing machines; installation and printing structures are divided into flat -pressure flat forms, round -voltage levels, and round -voltage round printing machines.
Printing machine
1. Classified according to the printing version
Link printing machine: Machines using the convex version to complete the printing process.Such as business card machines (resin version), diligence printing, zinc convex version, set number, etc.
Platform printing machine: Machines using the flat version to complete the printing process.Such as multi -color machines, four -color machines, dual -color machines, monochrome machines, fast printing machines, etc.
Caval printing machine: Machines using concave to complete the printing process.Such as the glass bag printing of instant noodles, biscuit aluminum foil bag packaging, etc.
Silk net printing machine: The machine using the silk network to complete the printing process.
Pole printing: such as network printing, circuit board printing, cloth flower printing, canned head printing, inscription printing, local light, etc.
2. Classification according to printing paper
Single paper printing machine: Use a single piece of paper printing machine.
Printing of roll paper: Printing machine with roll paper.
3. Classified by printing
Flat -up flat printing machine: The printing branches and the printed body are flat printing machines
The circular voltage printer (platform printing machine): The printing branch is flat, and the pressure printing is a cylindrical printing machine.
Stop the transit printing machine: The printing version cooperates to move back. When you move forward, press the roller to rotate for a week. When you return, the printed roller stops rotating to complete a printing process.
The transit printing machine: The printing station moves once again, and the printed roller is turned around for a week to complete a printing machine for printing.
Two Return Printing Machine: The printing station is moved once every time to complete a printing process of printing process
Repeat the printing machine: Each rotation of a roller is rotated to complete a printing machine for printing process.
Circular circular printing machine: The printed branches and the transferor are all cylindrical -like. When the printing process is completed, the printing machine is all rotated.
4. Classification according to printing ink color types
Monochrome printing machine: During a printing process, a printed printing machine is printed on the side of the paper.
Double -color printing machine: During a printing process, two ink printing machines are printed on the side of the paper.
Multi -color printing machine: During a printing process, printing more than two ink colors on the side of the paper.
Double -sided monochrome printing machine: During a printing process, printing machines on both sides of the paper are printed.
Double -sided multi -color printing machine: During a printing process, there are at least one -sided print printing machine with more than one side of the paper.
5. Classification according to use
General printing machines: Printing methods such as printing books, newspapers, product directory and other general objects as the main objects, and printed methods with the main purpose of transmitting information, such as book printing machines, newsletter printing machines, etc.
Special printing machines: Printing machines for special printing are mainly hose printing machines, non -dry glue label printing machines, and printers.
Principles
First make the text and images to be printed into a printing version, install it on the printing machine, and then apply the ink to the printing version of the text and images by manual or printing machine.Things (such as textiles, metal boards, plastic, leather, wooden boards, glass and ceramics), thereby copying the same prints as the printing version.
The principle of working principle of silk net printing machine: After transmitting the power by the transmission mechanism, let the ink scraping board squeeze the ink and screen printing version in the movement, so that the screen printing version and the printed material form a pressing line. Because the silk network has tension N1 andN2, generate force F2 for the ink scraping board, and the rebound force makes the wire printing version of the screen printing without contact with the bearing line except the printing line. Under the squeezing pressure F1 of the ink scratch plate, the ink is through the mesh.The printed lines are leaked on the bearing.
Ping-net curved wire screen printing machine working principle: A-roller branch B-axis support C-inlaid support.During printing, the printing version of the plane wire and the printed motion, while the ink scraping board is still.The printing version of the plane silk network is held on the mesh frame by the flat net curved wire screen printing machine to drive at a constant speed. Due to the friction of the network version, the bearing on the support device is rotated.The line speed of the curved bearing on the printing line is consistent with the movement speed of the plane screen printing version, and the ink scraping printing is achieved.
