[0001] The present application relates to the technical field of drying for gift box printing, and particularly to a drying device for packaging gift box printing. Background Art

[0002] Packaging printing is printing carried on various packaging materials, with decorative patterns, pictures or words printed on the packaging to make the product more attractive or more illustrative, thus playing the role of transmitting information and increasing sales volume. It includes the printing of packaging cartons, packaging bottles, packaging cans, etc. After the packaging gift box is printed, it is necessary to dry the ink and coating, which requires the use of a drying device.

[0003] The existing drying technology for packaging gift box printing mostly adopts the traditional hot air drying method, that is, hot air is blown to the printing surface through a fan to remove the moisture or solvent in the ink. However, due to the uneven distribution of hot air, some areas are over-dried while some areas are under-dried, affecting the drying effect. And because the high-temperature hot air directly acts on the printing surface, it may cause problems such as ink peeling off, color change or paper deformation, affecting the product quality. Utility Model Content

[0005] The drying device for packaging gift box printing provided by the present application adopts the following technical scheme:

[0006] A drying device for packaging gift box printing includes a drying cylinder provided with a hollow interior, two fixed cylinders, a feeding mechanism and a driving mechanism;

[0007] On the side walls of both of the two fixed cylinders, support legs are symmetrically and fixedly connected. On one side where the two fixed cylinders face each other, an installation groove is provided. Inside the installation groove, a fixed ring is rotatably installed. On the side wall of the fixed ring, a plurality of connection grooves are evenly provided. Inside each of the plurality of connection grooves, a conductive block is fixedly installed. Inside the installation groove and in contact with the inner wall of the conductive block, a conductive ring is fixedly installed;

[0008] The drying cylinder is fixedly installed between the two fixed rings. On the inner side wall of the drying cylinder, a plurality of infrared lamps for drying are evenly fixedly installed. The conductive block is electrically connected to the infrared lamp through an electric wire;

[0009] The feeding mechanism is arranged inside the two fixed cylinders and is used for conveying the packaging gift box;

[0010] The driving mechanism is arranged at the bottom of the drying cylinder and is used for driving the drying cylinder to rotate.

[0011] Preferably, the material feeding mechanism includes a motor and two frames. Fixed grooves are formed on the side walls of the two fixed cylinders, and the two frames are symmetrically and fixedly installed in the fixed grooves. Between the two frames, conveyor rollers are symmetrically and rotatably installed, and the two conveyor rollers are drivingly connected by a conveyor belt. The motor is fixedly connected to one side of one of the frames, and the output end of the motor is fixedly connected to one end of one of the conveyor rollers.

[0012] Preferably, the driving mechanism includes a driving motor, a first gear, and a second gear. A support plate is fixedly connected to the side walls of the plurality of support legs. The driving motor is fixedly connected to the upper surface of the support plate through a support block. The first gear is fixedly connected to the output end of the driving motor.

By continuously irradiating infrared radiation, the moisture or solvent in the ink on the packaging gift box is effectively removed, achieving the purpose of drying. Compared with the prior art, it has the advantages of using a plurality of infrared lamp tubes to perform all-round drying treatment on the packaging gift boxes on the conveyor belt, with good drying effect, ensuring the printing quality of the packaging gift boxes, and improving the practicability of the device.

DETAILED DESCRIPTION

[0022] The following is combined with Figures 1-4 This application is described in further detail.

[0023] The present application embodiment discloses a drying device for printing gift boxes. Figures 1-4 A drying device for packaging gift box printing comprises a hollow drying cylinder 1, two fixed cylinders 2, a feeding mechanism and a driving mechanism, the side walls of the two fixed cylinders 2 are symmetrically fixedly connected with support legs 6, the two fixed cylinders 2 are provided with mounting grooves 18 on opposite sides, a fixing ring 14 is rotatably installed inside the mounting groove 18, a plurality of connecting grooves 21 are evenly provided on the side walls of the fixing ring 14, a conductive block 17 is fixedly installed inside the plurality of connecting grooves 21, and a conductive ring 16 is fixedly installed inside the mounting groove 18 and in contact with the inner wall of the conductive block 17;

[0024] The drying drum 1 is fixedly installed between two fixing rings 14, and a plurality of infrared lamps 13 for drying are evenly fixedly installed on the inner wall of the drying drum 1, and the conductive block 17 is electrically connected to the infrared lamps 13 through wires (not shown in the figure);

[0025] The feeding mechanism is arranged in the two fixed cylinders 2 and is used to transport the packaged gift boxes. The feeding mechanism includes a motor 5 and two frames 4. The side walls of the two fixed cylinders 2 are provided with fixed grooves 19. The two frames 4 are symmetrically fixedly installed in the fixed grooves 19. A conveying roller 15 is symmetrically rotated and installed between the two frames 4. The two conveying rollers 15 are connected by a conveyor belt 3. The motor 5 is fixedly connected to one side of one of the frames 4. The output end of the motor 5 is fixedly connected to one end of one of the conveying rollers 15. A movable groove 20 is provided on the side wall of the fixed cylinder 2 at the top of the fixed groove 19. A plurality of through holes 11 are evenly spaced on the side wall of the conveyor belt 3. A through groove 12 is provided on the side wall of the frame 4.

[0026] The driving mechanism is arranged at the bottom of the drying cylinder 1 and is used to drive the drying cylinder 1 to rotate. The driving mechanism includes a driving motor 9, a first gear 10, and a second gear 22. A support plate 7 is fixedly connected to the side walls of multiple support legs 6. The driving motor 9 is fixedly connected to the upper surface of the support plate 7 through a support block 8. The first gear 10 is fixedly connected to the output end of the driving motor 9. The second gear 22 is sleeved on the side wall of the drying cylinder 1, and the second gear 22 meshes with the first gear 10.

[0027] During use, the electrical components in this application are externally connected to a power supply and a control switch when in use. By starting the motor 5, one of the conveyor rollers 15 can be driven to rotate, thereby driving the conveyor belt 3 and the other conveyor roller 15 to rotate synchronously. The printed packaging gift box is placed on the conveyor belt 3, and the conveyor belt 3 can convey the packaging gift box to the right. The packaging gift box can pass through the movable slot 20 and enter the interior of the drying cylinder 1.

By starting the driving motor 9, the first gear 10 can be driven to rotate. The first gear 10 can drive the drying cylinder 1 to rotate through the second gear 22. The drying cylinder 1 can drive the multiple infrared lamp tubes 13 inside to rotate. The model of the infrared lamp tubes 13 can be preferably selected by the staff according to the actual use situation. The infrared lamp tubes 13 generate infrared radiation. When the infrared radiation irradiates the surface of the packaging gift box, the molecules in the material will absorb this radiation energy, causing the molecular vibration to intensify, thereby generating heat. As the temperature rises, the moisture or solvent in the material begins to evaporate, forming a gas and being released from the surface of the material. By continuously irradiating infrared radiation, the moisture or solvent in the ink on the packaging gift box is effectively removed, achieving the purpose of drying. Through the through holes 11 on the conveyor belt 3 and the through slots 12 on the frame 4, it is ensured that the infrared lamp tubes 13 can perform a full-range drying treatment on the packaging gift box. While the drying cylinder 1 rotates, it can drive the fixed ring 14 to rotate in the installation slot 18, and the fixed ring 14 can drive the conductive blocks 17 to continuously rotate. Since the conductive blocks 17 are always in contact with the conductive ring 16, it is convenient to supply power to the rotating infrared lamp tubes 13. Since conductive blocks 17 are provided at both ends of the drying cylinder 1, it is convenient for the staff to connect the neutral wire and the live wire of the infrared lamp tubes 13. During this process, the driving motor 9 can drive the multiple infrared lamp tubes 13 in the drying cylinder 1 to rotate, so as to perform a full-range drying treatment on the packaging gift boxes on the conveyor belt 3, and the drying effect is good. At the same time, the printing quality of the packaging gift boxes is ensured, and the practicability of the device is improved.
