Printing and dyeing mechanism of a printing machine

Abstract

The invention relates to a sealed type ink supplying printing and dyeing mechanism of a printing machine. The printing and dyeing mechanism comprises an impressing roller, a forme roller and an anilox roller. The printing and dyeing mechanism is characterized in that an ink storage bar with a groove is arranged at one side of the anilox roller, the groove of the ink storage bar faces towards the anilox roller, two protruding edges which form the groove are respectively provided with a scraper, sealing parts are arranged inside the portions, at two ends of the scrapers, of the groove of the ink storage bar, the left sealing part, the right sealing part, the upper scraper, the lower scraper, the ink storage bar and the anilox roller form an ink storage cavity, printing ink holes are formed in the ink storage bar, and the ink storage cavity is communicated with an external printing ink conveyer device through the printing ink holes. According to the design of the printing and dyeing mechanism, printing ink can not splash out, the printing ink can not be ignited even though static electricity is generated in printing, and meanwhile odorous smell can not be generated either.

Description

technical field [0001] The invention relates to a printing machine, in particular to a printing and dyeing mechanism of the printing machine. Background technique [0002] The application range of the printing machine is very wide. The printing machine can print ink on the surface of different materials, and such materials include paper, cloth, plastic or metal, etc., and these all need to rely on the printing machine. [0003] present-day printing presses, see Figure 7 , the ink scraper devices are all space open, the printing machine is provided with a printing plate roller 400, one side of the printing plate roller 400 is provided with an anilox roller 401, one side of the anilox roller 401 is provided with an ink scraper 402, and the screen There is an ink pan 403 under the anilox roller 401. During actual printing, the printed material enters the printing plate roller 400, and the ink scraper 402 touches the anilox roller 401 to scrape off excess ink, and the ink is dr...

AI Technical Summary

Problems solved by technology

[0004] And this open printing method has the following serious disadvantages:

[0005] One: Since ink is a flammable item with a very low ignition point, the first taboo is fire and electricity. For smokers, they cannot operate the printing machine. When the machine is running, due to the friction between the material and the rollers, It is easy to generate static electricity. When the static electricity accumulates to a certain intensity, it is easy to generate sparks, which can easily cause the ink to catch fire. Once the fire occurs, the consequences will be disastrous

[0006] Two: When actually printing, it is necessary to add a diluent to the ink. The diluent includes solvents, toluene, ethanol, etc., and these diluents contain high carcinogens. During the process of adding the diluent, the diluent will volatilize and irritate Nasal and disgusting smells seriously affect the physical and mental health of operating workers

[0007] Three: During high-speed printing, the ink will splash with the anilox roller. If it splashes on the material to be printed, this section of material will become a waste product. If it splashes on the ground, it will be difficult to clean up, thus wasting a lot of ink

[0008] Four: In actual printing, because the ink tray does not have any ink discharge device, when printing at high speed, it is often necessary to add ink to the ink tray, and when the printing is stopped, the ink in the ink tray is difficult to clean, resulting in ink Utilization rate is not high
