Embodiment Construction
[0020] see Figure 1 to Figure 6 , the present invention mainly includes an air blowing device 10 and an air blowing control valve 13, wherein the air blowing control valve 13 includes an end cover 1, a cover plate 2, a valve body 3, a valve core 4, a trachea plug 5, a bearing 6 and a retaining ring 7 The blowing device 10 includes a branch air duct 14 , a mouthpiece connection chamber 15 , a mouthpiece 16 and an air volume adjustment knob 17 .
[0021] The working principle of the present invention is as follows: high-pressure gas enters the blowing control valve through the air inlet A, and a curved groove is processed on the valve core 4 of the blowing control valve according to the gas demand and blowing time. The high-pressure gas entering the blowing control valve passes through the curved groove on the valve core 4, is output through the air outlet B, and then enters the blowing device 10 through the gas outlet pipe 11, and the blowing device 10 applies the high-pressur...

An intermittent air supply type printing paper flattening device, comprising an air blowing device and an air blowing control valve, the air blowing control valve includes a valve body and a cylindrical valve core, and the valve core is embedded in the valve cavity of the valve body It is connected with the valve body through bearings. One end of the valve core protrudes from the valve body and is connected with the driving device. There is an air guiding groove on the cylindrical surface of the valve core. An air inlet and an air outlet corresponding to the air groove, the air inlet is connected with the high-pressure air source through the air inlet pipe, and the air outlet is connected with the blowing device through the air outlet pipe. The invention realizes the intermittent air supply through the rotary blowing control valve, which not only reduces the gas consumption and avoids the waste of energy, but also can eliminate the unstable phenomenon of the paper tail by reasonably controlling the air supply timing, thereby improving the quality of the paper. The flattening effect.
Description
technical field [0001] The invention relates to a device for flattening paper on an impression cylinder of a printing machine, belonging to the technical field of printing. Background technique [0002] At present, when printing, the printing machine needs to flatten the printing paper, and the flattening mechanism provides the required pressure through the wind, and flattens the paper on the impression cylinder by means of continuous air blowing. Due to the need for uninterrupted blowing, this flattening method not only consumes a lot of gas, but also tends to cause instability of the paper tail and affect the flattening effect of the paper, so it is necessary to improve it. Contents of the invention [0003] The object of the present invention is to solve the disadvantages of the prior art, and provide an intermittent wind-fed printing paper flattening device, so as to reduce gas consumption and improve the flattening effect of paper. [0004] Problem described in the p...
