Technical Field

[0001] The utility model relates to the technical field of printing devices, in particular to a quick-drying double-sided printing device for books and periodicals. Background Art

[0002] A printing press is a type of lithographic printing press. When printing, the printed image and text are first printed from the printing plate onto the rubber cylinder, and then transferred to the paper by the rubber cylinder. Printing presses can be divided into sheet-fed printing presses and web printing presses according to the different paper feeding methods. According to the number of printing colors completed in one paper feed, they can be divided into single-color, two-color, four-color and multi-color printing presses. According to the maximum paper format of the printing, they can be divided into small printing presses, six-page, four-page, double-page and full-sheet printing presses. In addition, there are double-sided printing presses that can complete printing on both sides at the same time in one paper feed. A sheet-fed printing press is a lithographic printing press, which is used to print high-end commercial printed products and packaging printed products.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5The utility model provides a technical solution: comprising a workbench 1, a double-sided printing device 2 is arranged on the upper surface of the workbench 1, and a quick-drying component 3 is arranged on one side of the double-sided printing device 2;

[0022] The quick-drying component 3 is provided with a groove on the upper surface of the workbench 1, and a drying box 301 is arranged inside the groove. The inner top wall of the drying box 301 and the inner bottom wall of the groove are rotatably connected with a swing rod 302 through a hinge seat, and a connecting frame is fixedly installed at one end of the swing rod 302, and a supporting frame 303 is fixedly installed at one end of the connecting frame. A plurality of drying fans 304 are fixedly installed on the inner side wall of the supporting frame 303, and a heating wire resistance plate 305 is fixedly installed on the inner side wall of the supporting frame 303. One side of the heating wire resistance plate 305 is electrically connected to a battery through a wire, and the battery is fixedly installed Mounted on one side surface of the supporting frame 303, a first slide groove 306 is provided on one side surface of the swing rod 302, a clamping column is slidably connected inside the first slide groove 306, a rotating plate 307 is fixedly installed on one end of the clamping column, a first driven column is fixedly installed on one end of the rotating plate 307, a driving motor 308 is fixedly installed on one side surface of the drying box 301, both sides of one side surface of the drying box 301 are rotatably connected with rotating shafts, one of the rotating shafts is fixedly installed on the output end of the driving motor 308, and a plurality of ventilation holes 309 are provided on the upper surface of the supporting frame 303.

[0023] After printing is completed by the double-sided printing device 2, the paper enters the interior of the drying box 301 and overlaps the surfaces of the first guide roller 5 and the pressure roller 6. The paper is tensioned by the reset force of the reset spring 7, and then the drying fan 304 and the battery are started to power the heating wire resistance plate 305. At the same time, the driving motor 308 is started to drive the rotating shaft to rotate. The rotating shaft is set through the first pulley and the second pulley to make the first driven columns on both sides of the interior rotate synchronously. The first driven column drives the rotating plate 307 at one end to rotate. The rotating plate 307 drives the swing rod 302 to slide in the first slide groove 306 through the clamping column, so that the swing rod 302 repeatedly swings with the hinge seat as the center of the circle. The swing rod 302 drives the bearing frame 303 at one end to move synchronously through the connecting frame, so that the drying fan 304 accelerates the drying of the ink on the surface of the paper in an all-round manner.

[0024] See also Figure 4 The first driven column and the outer surface of the rotating shaft are both fixedly mounted with a first pulley, the outer surfaces of the two rotating shafts are both fixedly mounted with a second pulley, and the outer surfaces of the first pulley and the second pulley are both overlapped with belts.

[0025] The arrangement of the first belt pulley and the second belt pulley enables the rotating plates 307 on the upper and lower sides to rotate synchronously, thereby causing the carrying frames 303 on the upper and lower sides to swing synchronously, thereby increasing the drying range of the device.

[0026] See also Figure 3 A dustproof net 4 is fixedly installed on the lower surface of the drying box 301 and the workbench 1, a first guide roller 5 is fixedly installed on both sides of the inner wall of the drying box 301, a telescopic plate is fixedly installed on both sides of the inner top wall of the drying box 301, a pressure roller 6 is fixedly installed at one end of the telescopic plate, and a return spring 7 is arranged inside the telescopic plate.

[0027] The first guide roller 5 guides the paper, and the pressure roller 6 and the return spring 7 are arranged so that the pressure roller 6 elastically squeezes the paper, thereby avoiding the occurrence of wrinkles on the paper and improving the drying quality of the device.

[0028] See also Figure 1 A support frame is provided on both sides of the double-sided printing device 2, and an overlapping roller 8 is provided on the outer surface of the support frame. Both sides of the outer surface of the overlapping roller 8 are slidably connected with a limiting member 9.

[0029] The overlapping rollers 8 guide the paper, and the limiting members 9 on both sides limit the paper to prevent the paper from deviating during transportation.

[0030] See also Figure 2 A U-shaped connecting piece 10 is fixedly installed on one end of each of the two limiting pieces 9 , and a fixing piece is fixedly installed on the lower surface of the U-shaped connecting piece 10 .

[0031] The limiting members 9 on both sides are connected by a U-shaped connecting member 10 to facilitate the movement of the limiting members 9 .

[0032] See also Figure 2 The internal threads of the two fixing parts are connected with a bidirectional screw rod 11, a first motor is fixedly installed on one side surface of the double-sided printing device 2, a driving shaft is fixedly installed on the output end of the first motor, and a bidirectional screw rod 11 is fixedly installed on one end of the driving shaft.

[0033] By starting the first motor to drive the bidirectional screw rod 11 to rotate, the distance between the limiting members 9 on both sides can be adjusted to accommodate papers of different widths.

[0034] Working principle:

[0035] The staff places the paper between the overlapping roller 8 and the double-sided printing device 2, and starts the first motor to drive the driving shaft and the bidirectional screw 11 to rotate. The rotation of the bidirectional screw 11 drives the fixing parts on the outer surface and the U-shaped connecting member 10 to move. The U-shaped connecting member 10 drives the limiting members 9 on both sides to move synchronously, so that the limiting members 9 slide on the outer surface of the overlapping roller 8. The movement of the paper is limited by the setting of the limiting members 9. At the same time, the spacing between the limiting members 9 on both sides can be adjusted to adapt to papers of different widths. After printing is completed by the double-sided printing device 2, the paper enters the interior of the drying box 301 and overlaps the surfaces of the first guide roller 5 and the pressure roller 6. The paper is stretched by the reset force of the reset spring 7. The drying fan 304 and the battery are then started to supply power to the heating wire resistance plate 305. At the same time, the driving motor 308 is started to drive the rotating shaft to rotate. The rotating shaft is configured through the first pulley and the second pulley to make the first driven columns on both sides of the interior rotate synchronously. The first driven column drives the rotating plate 307 at one end to rotate. The rotating plate 307 drives the swing rod 302 to slide inside the first slide groove 306 through the clamping column, so that the swing rod 302 repeatedly swings with the hinge seat as the center of the circle. The swing rod 302 drives the bearing frame 303 at one end to move synchronously through the connecting frame, so that the drying fan 304 accelerates the drying of the ink on the surface of the paper in all directions.
