Abstract
Description
Technical Field
[0001] This utility model belongs to the field of publication printing and processing technology, and specifically relates to a drying device. Background Technology
[0002] Publication printing is a complete process of mass-producing text, images, and other information onto paper and binding them into books. It mainly includes books, newspapers, periodicals, and magazines. The drying process in publication printing is crucial, as it directly affects the quality of the printed materials, production efficiency, and subsequent processing. By blowing hot air onto the printing surface, convection carries away the ink solvent and provides the heat required for oxidation, thus drying the publications.
[0003] Existing drying equipment uses a combination of a high-pressure blower and nozzles / airboxes to blow heated air evenly and at high speed onto the printing surface. This airflow carries away ink solvents and provides the heat needed for oxidation, resulting in a uniform and gentle drying process with minimal damage to the paper. A conveyor system transports the printed publications to the drying chamber, where nozzles direct hot air onto the surface, again carrying away ink solvents and providing the necessary heat for oxidation. However, in practice, the fixed blowing position of the high-pressure blower results in varying airflow volumes to different areas of the printing surface, potentially affecting the drying effect and subsequent processing. Utility Model Content
[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a drying device that uses hot air blown from the drying head to scan the printed publications to be dried back and forth like a fan. This movement greatly increases the coverage area of the hot air and effectively avoids the problems of local overheating or uneven drying caused by the publications being stationary or moving in one direction, thereby significantly improving the drying quality.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a drying device includes a conveyor base, a drying box fixedly installed in the middle of the conveyor base, two mounting plates symmetrically distributed around the vertical center of the drying box fixedly installed inside the drying box, multiple semi-circular rails fixedly installed between the two mounting plates, slide seats slidably installed on the outer side of each semi-circular rail, a drying head fixedly installed on the lower side of each slide seat, and an air outlet installed on the lower side of each drying head; a hot air box is installed on the rear side of the conveyor base, a telescopic air supply pipe is installed between the air outlet and the hot air box, the drying head is connected to the telescopic air supply pipe, multiple hot air blowers are fixedly installed inside the hot air box, and the interior of the hot air box is connected to the telescopic air supply pipe; multiple rotating rollers are rotatably installed inside the conveyor base, a conveyor belt is installed between the rotating rollers for transmission, a servo motor is installed on the outer side of the conveyor base, and the output shaft of the servo motor is fixed to the adjacent rotating rollers by a coupling.
[0006] As a further improvement of this utility model, a quarter-tooth ring is fixedly provided on the outer side of the slide, and a rotating shaft is rotatably provided inside the drying box. Multiple gears are fixedly provided on the outer arc surface of the rotating shaft, and the gears are respectively meshed with the vertically adjacent quarter-tooth rings. A worm is fixedly provided on the upper surface of the drying box, and a worm wheel is fixedly sleeved in the middle of the outer arc surface of the rotating shaft. The worm wheel and the worm are meshed with each other. A second servo motor is provided on the upper surface of the drying box, and the output shaft of the second servo motor is fixed to the worm through a coupling.
[0007] As a further improvement of this utility model, a glass observation window is provided on the front side of the drying oven.
[0008] As a further improvement of this utility model, four support plates are fixedly installed on the upper surface of the conveyor seat, evenly distributed around the vertical center of the conveyor seat. Each support plate is slidably provided with a sliding column. A limit plate is fixedly installed between the ends of two horizontally adjacent sliding columns that are close to the vertical center of the conveyor seat. An adjusting screw is rotatably installed in the middle of the limit plate. The adjusting screw is threadedly connected to the drying box. A handwheel is fixedly installed at the end of the adjusting screw that is away from the drying box.
[0009] As a further improvement of this utility model, four slide rods are fixedly installed on the outside of the conveyor seat, evenly distributed around the vertical center of the conveyor seat. A base frame is slidably installed between the bottom ends of the slide rods. Four sets of holes are evenly distributed around the vertical center of the conveyor seat on the base frame. Each set of holes includes multiple positioning holes evenly distributed vertically. Positioning bolts are inserted between the positioning holes and the adjacent slide rods. Nuts are threaded to the ends of the positioning bolts. Support feet are fixedly installed at the four corners of the lower surface of the base frame.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the servo motor drives the worm gear and worm wheel, which in turn drives the slide with a quarter-tooth ring to move back and forth in an arc trajectory on the semi-circular track. This causes the hot air blown out by the drying head to no longer blow directly but to scan the printed publications to be dried back and forth like a fan. This movement greatly increases the coverage area of the hot air and can effectively avoid the problems of local overheating or uneven drying caused by the publications being stationary or moving in one direction, thereby significantly improving the drying quality.
[0011] Secondly, the conveyor belt driven by the servo motor can realize continuous material conveying, which, combined with the arc-shaped sweeping motion of the drying head, forms a dynamic and continuous drying process. This helps to shorten the single drying cycle, is particularly suitable for mass production, and can significantly improve overall production efficiency.
[0012] Third, hot air is blown directly onto the material through the drying head, and because it is a dynamic scan, the heat can be distributed more evenly, which helps to reduce the retention and loss of heat in the cavity, thus achieving an energy-saving effect.
[0013] Fourth, the height of the conveyor seat can be easily adjusted by sliding the slide bar and using the positioning bolts and positioning holes. This function allows the equipment to flexibly adapt to printed publications of different thicknesses or specifications, enhancing the equipment's versatility. Attached Figure Description

Detailed Implementation

[0019] like Figure 2 , 3 As shown, quarter-tooth rings 208 are fixedly installed on the outer side of the slide 205. A rotating shaft 209 is rotatably installed inside the drying chamber 201. Multiple gears 210 are fixedly installed on the outer arc surface of the rotating shaft 209. The gears 210 mesh with the vertically adjacent quarter-tooth rings 208 respectively. A worm gear 215 is fixedly installed on the upper surface of the drying chamber 201. A worm wheel 213 is fixedly sleeved in the middle of the outer arc surface of the rotating shaft 209. The worm wheel 213 meshes with the worm gear 215. A servo motor 216 is installed on the upper surface of the drying oven 201. The output shaft of the servo motor 216 is fixed to the worm gear 215 by a coupling. A hot air box 211 is installed on the rear side of the conveyor seat 104. A telescopic air duct 212 is installed between the air outlet 207 and the hot air box 211. The drying head 206 is connected to the telescopic air duct 212. Multiple hot air blowers are fixedly installed inside the hot air box 211. The inside of the hot air box 211 is connected to the telescopic air duct 212.
[0020] like Figure 1 , 2 As shown, a glass observation window 202 is provided on the front side of the drying oven 201.
[0021] like Figure 1 , 2As shown, four support plates 106 are fixedly installed on the upper surface of the conveyor seat 104, evenly distributed around the vertical center of the conveyor seat 104. Each support plate 106 is slidably provided with a sliding column 107. A limit plate 108 is fixedly installed between the ends of two horizontally adjacent sliding columns 107 that are close to the vertical center of the conveyor seat 104. An adjusting screw 109 is rotatably installed in the middle of the limit plate 108. The adjusting screw 109 is threadedly connected to the drying box 201. A handwheel 110 is fixedly installed at the end of the adjusting screw 109 that is away from the drying box 201.
[0022] like Figure 1 , 2 As shown, four slide rods 103 are fixedly installed on the outer side of the conveyor seat 104, evenly distributed around the vertical center of the conveyor seat 104. A base frame 101 is slidably installed between the bottom ends of the slide rods 103. The base frame 101 has four sets of holes evenly distributed around the vertical center of the conveyor seat 104. Each set of holes includes multiple positioning holes 112 evenly distributed vertically. Positioning bolts 113 are inserted between the positioning holes 112 and the adjacent slide rods 103. Nuts are threaded to the ends of the positioning bolts 113. Support feet 102 are fixedly installed at the four corners of the lower surface of the base frame 101.
[0023] In use, sliding the slide rod 103 causes it to slide between the slide rod 103 and the base frame 101, thereby allowing the slide rod 103 to extend or retract from the inside of the base frame 101. Then, the positioning bolt 113 is inserted between the slide rod 103 and the adjacent positioning hole 112. Then, the nut is tightened by an external tool to fix the slide rod 103 to the base frame 101, thereby causing the slide rod 103 to drive the conveyor seat 104 to rise or fall, thereby adjusting the height of the conveyor seat 104. Then, the servo motor 111 is controlled to run, which causes the output shaft of the servo motor 111 to drive the roller connected to it to rotate, which in turn drives the conveyor belt 105, which is configured to drive multiple rollers, to rotate. Then, the printed publications to be dried are placed on the conveyor belt 105, and the printed publications are transported by the rotation of the conveyor belt 105. Then, the output shaft of servo motor 216 is controlled to rotate in both forward and reverse directions, causing the output shaft of servo motor 216 to drive the worm gear 215 connected to it to rotate in both forward and reverse directions. During the rotation of worm gear 215, the meshing relationship between worm gear 215 and worm wheel 213 drives the rotating shaft 209 where worm wheel 213 is located to rotate in both forward and reverse directions, causing multiple gears 210 fixedly set on the outer arc surface of rotating shaft 209 to rotate in both forward and reverse cycles. Through the forward and reverse cycle rotation of gears 210, the slide 205 where quarter-tooth ring 208 is located is driven to move cyclically back and forth on semi-circular track 204 in an arc trajectory, thereby... The drying head 206 on the lower side of the slide 205 moves back and forth in an arc trajectory. The worm gear 215 and worm wheel 213 are driven by the servo motor 216, which drives the slide 205, which is equipped with a quarter-tooth ring 208, to move back and forth in an arc trajectory on the semi-circular track 204. This makes the hot air blown out by the drying head 206 no longer blow directly, but scans the printed publications to be dried back and forth like a fan. This movement greatly increases the coverage area of the hot air and can effectively avoid the problem of local overheating or uneven drying caused by the publications being stationary or moving in one direction, thereby significantly improving the drying quality. During this process, the hot air blower is controlled to deliver hot air through the telescopic air duct 212 into multiple drying heads 206 that move back and forth in an arc trajectory. Then, the hot air moves back and forth in an arc trajectory through the air outlet 207 on the lower side of the drying head 206, so that the hot air can be blown evenly onto the printed publications conveyed by the conveyor belt 105, and perform multi-directional rapid and uniform drying processing on the printed publications.
[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
