[0023] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined invention purpose, the following, in conjunction with the attached drawings and preferred embodiments, details the specific implementation mode, structure, features and their effects of the present utility model as follows.

[0024] As Figures 1-4 shown, a fast-drying device for printing ink includes a protection box, an ultraviolet lamp 8, a roller group 4 and a heating tube 7. The ultraviolet lamp 8, the roller group 4 and the heating tube 7 are respectively installed in the protection box from top to bottom. Corresponding notches 13 are provided on both sides of the protection box for cardboard to pass through. The roller group 4 is arranged parallel to the notch 13, and the upper end surface of the roller group 4 is within the height range of the notch 13, which can roll and support the cardboard to prevent the cardboard from rubbing against the upper and lower ends of the notch 13. In addition, a first roller 5 and a second roller 6 are provided at corresponding positions on both sides of the protection box to receive the cardboard outside the protection box in advance. The ultraviolet lamp 8 is located above the notch 13 to cure the ink on the upper surface of the cardboard. After the cardboard is printed, it enters from the notch 13 on one side of the protection box, the ink on the cardboard is cured by the ultraviolet lamp 8, and then the lower end surface of the cardboard is baked by the heating tube 7 to accelerate the drying of the ink. After the cardboard passes out from the notch 13 on the other side of the protection box, the residual temperature of the cardboard is used to continue to affect the ink to make it continue to dry slowly. The heating tube 7 is distributed in a circuitous manner in the protection box to ensure comprehensive and uniform baking effect. The ultraviolet lamp 8 is arranged parallel to the notch 13, and the ultraviolet lamp 8 is located on the side of the notch 13. The notches 13 on both sides of the protection box are respectively the entrance and the exit. The ultraviolet lamp 8 is installed near the exit. After the cardboard enters the protection box, the ink on the cardboard approaches the ultraviolet lamp 8 from far to near, and the irradiation intensity and irradiation effect of the ultraviolet lamp 8 on the ink gradually increase, forming a step-by-step enhanced curing effect. On the premise of ensuring that the ink is fully cured, it is prevented that the ink curing speed is too fast, resulting in its skinning, plate sticking, ink accumulation, poor gloss or ink spots on the printed matter.

[0025] In the above embodiments, the protection box includes a box body 2 and a box cover 3. Upper notches 1301 are provided at the lower ends of both sides of the box cover 3, and lower notches 1302 are provided at the upper ends of both sides of the box body 2. The upper notches 1301 and the lower notches 1302 enclose the notch 13. The box cover 3 is hinged to the side of the box body 2. The box cover 3 can be flipped along the hinge to separate the upper notches 1301 and the lower notches 1302 on both sides of the protection box. After the box cover 3 is lifted and the notch 13 is opened, an operator can easily pass a cardboard through and place it on the roller group 4 during the preparation stage, and it is also easy to clean the phenomenon of cardboard jamming that occurs during use, and the operation is convenient and fast. The box body 2 and the box cover 3 are connected by a pneumatic spring 10. The side surface of the upper end of the pneumatic spring 10 is hinged to the box cover 3, and the side surface of the lower end of the pneumatic spring 10 is hinged to the box body 2. The pneumatic spring 10 is used to maintain the state of the box cover 3, keep it stable after the box cover 3 is closed or lifted, ensure the airtightness during the closed operation to prevent ultraviolet light leakage and heat loss, or ensure the suspension during the lifting operation to free the operator's hands and avoid the box cover 3 falling and hurting people; at the same time, the presence of the pneumatic spring 10 makes there no any blocking objects between the front part of the box cover 3 and the box body 2 when the box cover 3 is lifted, further improving the convenience of the operation.

[0026] In the above embodiment, an upper touch switch 14 and a lower touch switch 15 with corresponding positions are respectively provided on the side surface of the box cover 3 and the side surface of the box body 2, and the upper touch switch 14 can abut against the lower touch switch 15; when the upper touch switch 14 and the lower touch switch 15 are in contact, the circuits of the ultraviolet lamp 8 and the heating tube 7 are conducted, and both enter the working state; when the upper touch switch 14 and the lower touch switch 15 are separated, the circuits of the ultraviolet lamp 8 and the heating tube 7 are disconnected and stop working immediately; in practical applications, this design is for safety and convenience considerations. When a cardboard jam needs to be urgently processed, the box cover 3 can be lifted for operation, and at the moment when the box cover 3 is lifted, the ultraviolet lamp 8 and the heating tube 7 stop immediately, preventing ultraviolet light from hurting people and avoiding waste of electricity by the heating tube 7. A set of deviation correction guide wheels 12 is provided on the side surface of the box cover 3. The set of deviation correction guide wheels 12 is located on the side of the upper notch 1301. The cardboard is clamped in the middle by two deviation correction guide wheels 12, one on the left and the other on the right. Under the rolling connection between the cardboard and the deviation correction guide wheels 12, the situation that the two sides of the cardboard are damaged by rubbing against the notch 13 is avoided, and it is also beneficial to the centered conveying of the cardboard in continuous production, facilitating the next printing process. A support plate 11 is provided on the side surface of the box cover 3. A horizontal groove 1101 is provided in the support plate 11. The upper ends of the set of deviation correction guide wheels 12 are movable and installed in the horizontal groove 1101. The widths of the two deviation correction guide wheels 12 can be adjusted according to the size of the cardboard, obtaining the same deviation correction effect when using cardboard of different sizes, avoiding the deviation correction effect from being not obvious due to too large a distance between the cardboard and the deviation correction guide wheels 12, or avoiding the deviation correction guide wheels 12 squeezing the cardboard and causing it to deform. A handle is provided on the side surface of the box cover 3, facilitating the operator to lift the box cover 3. An arc-shaped reflector 9 is provided inside the box cover 3. The arc-shaped reflector 9 is located above the ultraviolet lamp 8, reflecting the light of the ultraviolet lamp 8, avoiding the disorder of light, and improving the utilization rate of light. Two knobs 17 are provided on the front side of the box body 2. The two knobs 17 are respectively electrically connected to the ultraviolet lamp 8 and the heating tube 7. The end of the counterclockwise rotation of the knob 17 is the zero position. When rotated clockwise, the ultraviolet lamp 8 and the heating tube 7 are started, and the circuit current is gradually increased with the rotation, increasing the working power of the ultraviolet lamp 8 and the heating tube 7 to improve the curing effect of the ultraviolet lamp 8 and the baking effect of the heating tube 7. Two display boards 16 are provided on the front side of the box body 2. The two display boards 16 are respectively electrically connected to the two knobs 17, and can display the instantaneous power of the ultraviolet lamp 8 and the instantaneous temperature of the heating tube 7, facilitating the operator to adjust. A support platform 1 with adjustable height is provided at the lower end of the box body 2. Through the form of up and down insertion and the use of the pin hole 101 and the pin, the height of the support platform 1 is controlled to adapt to the height of the production equipment.

[0027] Description of the working mode of the present utility model:

[0028] When producing partial-color boxes, the cardboard needs to be printed in batches and layers to ensure the adhesion between inks and the printing quality. Two printing devices are arranged on the same production line, and this device is installed between the two printing devices to quickly dry the first-layer printing ink, so that it can quickly enter the processing of the second-layer printing ink, ensuring that the first-layer printing ink is cured and dried to a certain extent, meeting the printing conditions for printing the second-layer ink, achieving continuous processing, saving the space and time required for cardboard transfer, and improving the printing efficiency and the output of color boxes. The specific operation process is as follows: The front trial printing section of the continuous cardboard is pulled into the traction device. At this time, the middle section of the continuous cardboard is placed on the roller group 4 of this device. By adjusting the overall height of the support table 1, the entire section of the continuous cardboard is in a horizontal state. Then, the position of the deviation correction guide wheel 12 group is adjusted so that there is a certain gap between the continuous cardboard and the deviation correction guide wheels 12 on both sides. While ensuring the smooth passage of the continuous cardboard, it limits and corrects the deviation of the continuous cardboard to ensure that the continuous cardboard remains centered on the production line, thereby ensuring the accuracy of front and back printing; after adjustment, cover the box cover 3, turn on the ultraviolet lamp 8 and the heating tube 7 through the knob 17. After observing the display board 16 and adjusting the knob 17 to specific process parameters, the printing operation of the ink can be carried out. The first printing device prints the first-layer ordinary ink on the cardboard. When passing through this device, under the curing effect of the ultraviolet lamp 8 and the baking effect of the heating tube 7, the first-layer printing ink is quickly dried to a certain extent. After the cardboard passes through this device, the residual temperature of the cardboard continues to dry the printing ink, achieving a natural transition drying effect; after passing through this device, the cardboard enters the second printing device, and the second-layer gold and silver ink can be directly printed on the first-layer printing ink. The second-layer gold and silver ink has good adhesion on the first-layer ordinary ink. In the final finished color box, the two layers of printing ink are perfectly combined, meeting the printing requirements. In this device, the printing ink approaches the ultraviolet lamp 8 from far to near, forming a stepped curing effect, avoiding the adverse effects brought by rapid high-intensity curing and ensuring the curing quality of the printing ink. When it is necessary to replace the continuous cardboard, just directly open the box cover 3 of the protection box, and the operation of the ultraviolet lamp 8 and the heating tube 7 of this device can be automatically stopped, ensuring personnel safety and reducing energy consumption; using this device can greatly improve the printing speed of the ink, shorten the length of the production line. At the same time, this device can also adapt to the printing of multiple layers of inks with different formulas, realizing the integration of multiple processes and greatly improving the production efficiency.
