Description

Technical Field

[0001] This utility model relates to the field of rapid drying technology for printing, and in particular to a drying mechanism for carton printing. Background Technology

[0002] A carton printing machine is a printing device that can print the required text, patterns and other information onto the surface of a carton. It generally includes processes such as plate mounting, inking, printing, and paper feeding. Carton printing generally includes single printing, printing with slotting, die cutting, printing with slotting, die cutting, gluing, and integrated production lines. In the production process of cartons and cardboard, a rapid drying device for carton and cardboard printing can quickly dry the printed cartons or cardboard to prevent the printing ink from being smudged.

[0003] In existing carton printing drying technology, hot air is usually blown out through air ducts to dry the printed cartons. This method can effectively deliver hot air to the surface of the cartons, accelerating the ink drying process and ensuring the clarity and quality of the printed patterns. However, existing drying mechanisms generally have a limitation: the position of the air duct is fixed and cannot be adjusted up or down according to the size of the cartons and the need for localized drying. The fixed position of the air duct limits the distribution of hot air and the uniformity of drying. For cartons of different sizes and shapes, and for different positions of the printed patterns on the cartons, the fixed air duct often cannot provide the best drying effect. Especially when it is necessary to locally dry specific areas of the cartons, the uneven distribution of hot air will lead to unsatisfactory drying results, which in turn will affect the overall quality and appearance of the cartons. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a drying mechanism for carton printing, which aims to improve the problem that the existing drying mechanism for carton printing cannot drive the air outlet pipe to move.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying mechanism for carton printing, comprising a conveyor belt, a fixed cover fixedly connected to the upper part of the conveyor belt, a double-headed motor fixedly connected to the upper part of the fixed cover, a rotating shaft fixedly connected to the output end of the double-headed motor, gears fixedly connected to the ends of the two rotating shafts that are far apart, toothed columns meshing with one side of each of the two gears, mounting plates fixedly connected to the bottom of each of the two toothed columns, fixed pipes fixedly connected to opposite sides of each of the two mounting plates, air outlet pipes fixedly connected to opposite sides of each of the two fixed pipes, a fan fixedly connected to the upper part of the fixed cover, a heating box fixedly connected to the output end of the fan, a three-way pipe fixedly connected to the left side of the heating box, one end of each air supply hose fixedly connected to both ends of the three-way pipe, the other ends of each of the two air supply hoses fixedly connected to the upper part of the fixed pipe, and heating pipes fixedly connected to the four sides of the interior of the heating box.

[0007] Furthermore, a filter screen is fixedly connected inside the heating box, and the filter screen is located on one side of the heating tube.

[0008] Furthermore, both of the fixed pipes are slidably connected to the inside sides of the fixed cover, and the multiple air outlet pipes are slidably connected to the inside sides of the fixed cover.

[0009] Furthermore, upright plates are fixedly connected to both sides of the upper part of the fixed cover, and the two rotating shafts are rotatably connected inside the upright plates.

[0010] Furthermore, hinge blocks are fixedly connected to both sides of the inner side of the fixed cover, and one end of a movable support rod is rotatably connected to both sides of the outer side of the two hinge blocks.

[0011] Furthermore, each of the multiple movable support rods 1 has a movable support rod 2 rotatably connected to its other end, and the other ends of the multiple movable support rods 2 are rotatably connected inside the positioning block.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3This utility model provides an embodiment of a drying mechanism for carton printing, comprising a conveyor belt 1, a fixed cover 2 fixedly connected to the upper part of the conveyor belt 1, a double-headed motor 3 fixedly connected to the upper part of the fixed cover 2, a rotating shaft 4 fixedly connected to the output end of the double-headed motor 3, gears 5 fixedly connected to the opposite ends of the two rotating shafts 4, toothed columns 6 meshing with one side of each of the two gears 5, mounting plates 7 fixedly connected to the bottom of each of the two toothed columns 6, fixed pipes 8 fixedly connected to opposite sides of each of the two mounting plates 7, and air outlet pipes 9 fixedly connected to opposite sides of each of the two fixed pipes 8, a fan 10 fixedly connected to the upper part of the fixed cover 2, and a heating box 11 fixedly connected to the output end of the fan 10, with the left side of the heating box 11... A three-way pipe is fixedly connected to the heating box 11. One end of each of the two ends of the three-way pipe is fixedly connected to a flexible air supply hose 14. The other ends of the two flexible air supply hoses 14 are fixedly connected to the upper part of the fixed pipe 8. Heating pipes 13 are fixedly connected to the inside of the heating box 11. A filter screen 12 is fixedly connected to the inside of the heating box 11. The filter screen 12 is located on one side of the heating pipe 13. The two fixed pipes 8 are slidably connected to the inside of the fixed cover 2 on both sides. Multiple air outlet pipes 9 are slidably connected to the inside of the fixed cover 2 on both sides. Vertical plates are fixedly connected to the upper part of the fixed cover 2. Two rotating shafts 4 are rotatably connected to the inside of the vertical plates. The heating box 11 is fixedly connected to the upper part of the fixed cover 2. The two flexible air supply hoses 14 are inserted through the inside of the fixed cover 2 on both sides.

[0023] After the cardboard boxes are secured, the blower 10 is activated to draw in air and deliver it to the heating chamber 11 for heating. During this process, the air first passes through a filter 12 to remove impurities, and then is heated by the heating element 13. Before heating, the filter 12 removes dust and other impurities from the air to ensure the air entering the heating chamber 11 is clean and prevents contamination of the cardboard boxes. The heating element 13 heats the air to a certain temperature to provide sufficient heat during the drying process. The hot air is then delivered to the air delivery hose 14 through a three-way pipe. The hot air reaches the fixed pipe 8 and is finally blown out through the air outlet pipe 9. The air outlet pipe 9 is the channel for hot air discharge. It guides the hot air from the fixed pipe 8 to the carton, ensuring that the hot air can be blown evenly to the surface of the carton. At the same time, the dual-head motor 3 is activated, and its output end drives the rotating shaft 4 to rotate, which drives the gear 5 to mesh and rotate, thereby driving the gear column 6 to move. The movement of the gear column 6 causes the mounting plate 7 to move accordingly, thereby driving the fixed pipe 8 and the air outlet pipe 9 to adjust up and down inside the fixed cover 2, so that the air outlet pipe 9 can move back and forth flexibly to dry the carton evenly.

[0024] Reference Figure 3A hydraulic cylinder 15 is fixedly connected inside the fixed cover 2. A positioning block 16 is fixedly connected to the output end of the hydraulic cylinder 15. A pressure plate 17 is fixedly connected to the bottom of the positioning block 16. The pressure plate 17 is located on the upper part of the conveyor belt 1. Hinges 18 are fixedly connected to both sides inside the fixed cover 2. One end of a movable support rod 19 is rotatably connected to both sides of the outside of the two hinge blocks 18. The other end of the multiple movable support rods 19 is rotatably connected to a movable support rod 20. The other end of the multiple movable support rods 20 is rotatably connected inside the positioning block 16.

[0025] The conveyor belt 1 is used to smoothly feed the carton from the starting position into the fixed cover 2. Its function is to provide a continuous and smooth transportation method, ensuring that the carton will not shift or be damaged before entering the drying area. During this process, the hydraulic cylinder 15 is activated, and its output end drives the positioning block 16 to move downward. As the positioning block 16 moves, multiple movable support rods 19 and 20 rotate accordingly and work together. Movable support rods 19 and 20 are movable parts connected to the positioning block 16. They rotate accordingly when the positioning block 16 moves. The function of movable support rods 19 and 20 is to provide support and stability when pressing the carton, so that the pressure plate 17 can be pushed downward stably. This process finally presses the carton firmly, ensuring that the carton remains stable during the drying process.

[0026] Working principle: The cardboard box is placed on the upper part of the conveyor belt 1, which then conveys the box into the interior of the fixing cover 2. Next, the hydraulic cylinder 15 is activated, and its output pushes the positioning block 16 downward. As the positioning block 16 moves, it drives multiple movable support rods 19 and 20 to rotate. With the cooperation of the movable support rods 19 and 20, the positioning block 16 drives the pressure plate 17 to move downward steadily until the cardboard box is pressed down. This effectively presses and fixes the cardboard box, making it more stable during the drying process, reducing displacement and deformation, and helping to maintain the clarity and color consistency of the printed pattern. After the cardboard box is fixed, the fan 10 is activated to draw in air and deliver cold air into the heating chamber 11. After being filtered by filter screen 12, the air is heated by heating tube 13. The heated hot air is then delivered to air delivery hose 14 through a three-way pipe, and then to fixed pipe 8 through air delivery hose 14. Finally, it is blown out through air outlet pipe 9. At the same time as the hot air is blown out, the dual-head motor 3 is started. The output end of the dual-head motor 3 drives the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it drives the two gears 5 to rotate. When the two gears 5 rotate, they drive the meshing gear column 6 to move. When the gear column 6 moves, it drives the mounting plate 7 to move. The mounting plate 7 drives the fixed pipe 8 and the air outlet pipe 9 to move up and down inside the fixed cover 2. This allows for easy movement of the air outlet pipe 9 back and forth in the drying box, which can change the distribution pattern of the hot air and make local adjustments for the drying needs of different areas, so as to make the drying effect more uniform.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
