Embodiment 1

[0026] figure 1 It is a structural schematic diagram of an offset printing machine with an enhanced drying system, figure 2 It is a schematic diagram of the partial structure of the transmission part and the printing part, image 3 It is a schematic diagram of the structure of the suction and blowing device, Figure 4 It is a 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 machine with an enhanced drying system includes a printing part 1, a paper conveying part 2 and a delivery table 3; the printing part 1 includes a printing roller rotatably arranged on a frame 10 11. The paper conveying part 2 includes a coating idler roller 21 and a delivery roller 22 which are rotatably arranged on the frame 10, and which rotate counterclockwise with the coating roller 11 under the action of the coating roller 11;

[0027] The curved surface of the printing roller 21 is provided with severa...

Embodiment 2

[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 are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be 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 Several UVLED lamps 72; UVLED lamps 72 are used for further drying, so that the drying effect is good, and power saving and low cost; in addition, a number of UVLED lamps 72 are set, and the number of UVLED lamps 72 that are turned on can be controlled according to actual drying requirements degree of dryness.

Embodiment 3

[0034] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the parts that are the same as or corresponding to those in the second embodiment are marked with the corresponding reference numerals in the second embodiment. For the sake of simplicity, only the differences from the second embodiment will be described below. The difference between the third embodiment and the second embodiment is that: the sensor a8 fixed on the frame 10 is arranged above the parabolic segment 25; the sensor a8 fixed on the frame 10 is arranged below the parabolic segment 25 b9; the driving roller 24 includes a roller 241 and a servo motor 242; the servo motor 242 is fixed on the frame 10 and is respectively signal-connected with the sensor a8 and the sensor b9; For reasonable control, it is preferable to set the sensor a8 and the sensor b9 here as distance sensors. When the arc of the parabolic segment 25 is large, the paper 20 approaches the sensor b9 below, and the sensor b9 sends a ...

Abstract

The invention discloses an offset press with an enhanced type drying system. The offset press comprises a coating-printing part, a sheet transmission part and a sheet collecting table, wherein the sheet transmission part comprises a coating-printing supporting roller and a sheet collecting roller, which can be rotatably arranged on the rack, and reversely rotate along with a coating-printing pressure roller under action of the coating-printing pressure roller; a plurality of through holes are formed in a curved surface of the coating-printing supporting roller; an absorbing-blowing device is arranged inside the coating-printing supporting roller; the absorbing-blowing device comprises a blowing-absorbing fan, an air-blowing cover which communicates with an air outlet of the blowing-absorbing fan, and an air absorbing cover which communicates with an air suction hole of the blowing-absorbing fan; an opening of the air-blowing cover faces towards a position where a sheet is to be transmitted away from the coating-printing supporting roller; an opening of the air-absorbing cover faces towards a position where the sheet is to be transmitted to enter the coating-printing pressure roller and the coating-printing supporting roller; a sheet intake direction of the coating-printing supporting roller is equipped with an air-absorbing correcting device; and the air-absorbing correcting device communicates with the air-absorbing cover through a pipeline. The offset press overcomes the problems that an offset press in the prior art is poor in drying effect, is high in energy consumption and is inaccurate in coating-printing.

Description

technical field [0001] The invention relates to the technical field of printing machinery, in particular to an offset printing machine with an enhanced drying system. Background technique [0002] The offset printing machine is a kind of lithographic printing machine. When printing, the printed image and text are first printed from the printing plate to the rubber cylinder, and then transferred to the paper by the rubber cylinder. Offset printing machines can be divided into sheet-fed offset printing machines and web offset printing machines according to different feeding methods; according to the number of printing colors completed in one pass, they can be divided into single-color, two-color, four-color and multi-color printing machines; The largest paper format can be divided into small offset printing machines, six-fold, four-fold, folio and full-sheet printing machines, and there is also a double-sided printing machine that can print on both sides at the same time with ...
