[0025] Example one
[0026] figure 1 Schematic diagram of the offset press with an enhanced drying system, figure 2 Is the partial structure diagram of the transmission part and the coating part, image 3 Is a schematic diagram of the structure of the suction and blowing device, Figure 4 Schematic diagram of the structure of the UV drying device. Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, an offset printing press with an enhanced drying system includes a coating part 1, a paper conveying part 2 and a delivery table 3; the coating part 1 includes a coating press roller rotatably arranged on a frame 10 11; The paper conveying part 2 includes a rotatably arranged on the frame 10, under the action of the coating roller 11, the coating roller 21 and the delivery roller 22 that rotate counter-rotating with the coating roller 11;
[0027] The surface of the coating roller 21 is provided with a number of through holes 211; the coating roller 21 is provided with a suc...
Example Embodiment
[0031] Example two
[0032] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the components that are the same as or corresponding to those in the first embodiment use the reference numerals corresponding to those in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that: a UV drying device 7 is provided in the paper output direction of the coating roller 21; the UV drying device 7 includes a support 71 and is evenly arranged on the support 71 A number of UVLED lamps 72; the use of UVLED lamps 72 for further drying, so that the drying effect is good, and energy saving, low cost; In addition, a number of UVLED lamps 72 are set up, which can be controlled by controlling the number of UVLED lamps 72 that are turned on according to actual drying requirements The degree of dryness.
Example Embodiment
[0033] Example three
[0034] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the components that are the same as or corresponding to those in the second embodiment adopt the reference numerals corresponding to the second embodiment. For simplicity, only the differences from the second embodiment are described below. The third embodiment is different from the second embodiment in that: a sensor a8 fixed on the frame 10 is arranged above the parabolic section 25; a sensor fixed on the frame 10 is arranged below the parabolic section 25 b9; the active roller 24 includes a roller 241 and a servo motor 242; the servo motor 242 is fixed on the frame 10 and is connected to the sensor a8 and the sensor b9 signal respectively; the sensor a8 and the sensor b9 can carry out the arc of the parabolic section 25 Reasonable control, here it is preferable to set both sensor a8 and sensor b9 as distance sensors. When the arc of the parabolic section 25 is large, the paper 20 appro...
