Description

Technical Field

[0001] The utility model relates to the technical field of color box printing and drying, in particular to an efficient drying device for color box printing. Background Art

[0002] Before leaving the factory, color boxes are printed with colored patterns or texts on their surfaces. Currently, most color box printing devices are used to achieve the above purpose. After color box printing, drying treatment is required to dry the patterns and texts on the color boxes through a drying device.

[0003] For example, the patent publication number CN202120999553.8 discloses a high-efficiency color box printing device. This solution installs a gantry on the frame and a hot air blower on the gantry to achieve the drying treatment of the lower color boxes. However, there are some deficiencies in this drying method. For example, the hot air blower can only dry the lower color boxes, with a large drying limitation, resulting in a short drying time for the color boxes. It cannot perform tracking drying treatment on the color boxes, thereby increasing the drying time and the drying effect is not ideal. Therefore, improvement is needed. Summary of the Utility Model

By setting two exhaust pipes, efficient operation is ensured, and the situation of untimely drying caused by a large number of color boxes is avoided, solving the problem of poor drying effect of the current device.

[0025] Embodiment

[0026] Such as Figure 1 、 Figure 2 And Figure 3As shown in the figure, a high-efficiency drying device for color box printing proposed by an embodiment of the present utility model includes: a gantry 1, and an exhaust connection 3 is provided on a hot air blower 2 fixed on one side of the gantry 1; a drying module 5, including an L-shaped pipe 501 connected to the exhaust connection 3, and a rotary joint 504 rotatably connected to one side of the L-shaped pipe 501. A first exhaust pipe 505 is connected to the bottom of the rotary joint 504, and a driven gear 503 is fixedly connected to the rotary joint 504; an angle adjustment module 4, including a first shaft 401 and a second shaft 405 rotatably connected to the gantry 1. A second exhaust pipe 6 is fixedly connected to the first shaft 401, and a first driving gear 406 is fixedly connected to the second shaft 405. The first driving gear 406 is meshed with the driven gear 503, and synchronous wheels 402 are fixedly connected to both the first shaft 401 and the second shaft 405. A synchronous belt 404 is arranged between the two synchronous wheels 402. The first shaft 401 and the second shaft 405 can rotate in the same direction. The second shaft 405 drives the rotary joint 504 to rotate through the relationship of the first driving gear 406 and the driven gear 503, so that the first exhaust pipe 505 and the second exhaust pipe 6 rotate in opposite directions, realizing the tracking drying treatment of different color boxes.

[0027] It should be noted that the gantry 1 can be fixed on the frame of the printing equipment. By installing the hot air blower 2 on the gantry 1, the hot air blower 2 can generate hot air and discharge it through the exhaust connection 3. By setting the drying module 5 and the second exhaust pipe 6, wherein the drying module 5 is mainly composed of an L-shaped pipe 501, a driven gear 503, a rotary joint 504 and a first exhaust pipe 505. The L-shaped pipe 501 is connected to the exhaust connection 3, and the rotary joint 504 is rotatably connected to the L-shaped pipe 501. When rotating, it can adjust the angle of the first exhaust pipe 505 to realize the tracking drying treatment of the color box. The second exhaust pipe 6 is fixed on the first shaft 401. When the first shaft 401 rotates, it can drive the second exhaust pipe 6 to rotate. The first exhaust pipe 505 and the second exhaust pipe 6 alternately dry the color box to ensure the drying speed. Synchronous wheels 402 are fixedly connected to both the first shaft 401 and the second shaft 405. A synchronous belt 404 is arranged between the two synchronous wheels 402, so that the first shaft 401 and the second shaft 405 can rotate in the same direction, and the first driving gear 406 is meshed with the driven gear 503, and then the rotary joint 504 and the first shaft 401 rotate in opposite directions, so that the first exhaust pipe 505 and the second exhaust pipe 6 rotate in opposite directions. When the first exhaust pipe 505 performs the tracking drying treatment on the color box, the second exhaust pipe 6 rotates in the opposite direction for resetting. During the resetting process, no air is sprayed, and it is ready for the next drying action, so that the first exhaust pipe 505 and the second exhaust pipe 6 alternately perform continuous drying of the color box. On the one hand, the drying speed is ensured, and on the other hand, due to the tracking drying, the drying treatment time is long, and thus the drying effect is improved.

The hard pipes 7 and the flexible pipe 8 do not come into contact with the first exhaust duct 505 and will not cause interference. By installing valves 502 on both the L-shaped pipe 501 and one of the hard pipes 7, the supply of air to the first exhaust duct 505 and the second exhaust duct 6 can be controlled.

[0033] Such as Figure 1 and Figure 2 As shown in Figure 1 and Figure 2 , in some embodiments, the second exhaust duct 6 is arranged parallel to the first exhaust duct 505 below it. This design method enables the two exhaust ducts to rotate independently of each other, alternately drying the color boxes, and ensuring the operation efficiency.

[0034] Such as Figure 4As shown, different from the above solution, the present utility model can also control the rotation of the driven gear 503 through the vertical plate 9, the second motor 10, the round rod 11 and the second driving gear 12, and then realize the rotation control of the rotary joint 504 and the first exhaust duct 505, separately realize the rotation adjustment of the first exhaust duct 505 and the second exhaust duct 6, which is convenient for separate rotation control and adjust the rotation speeds of the first exhaust duct 505 and the second exhaust duct 6; in this way, the second motor 403 directly controls the rotation of the second exhaust duct 6, and the second motor 10 controls the rotation of the round rod 11 to realize the angle adjustment of the rotary joint 504 and the first exhaust duct 505. The vertical plate 9 is fixed on the gantry 1, the second motor 10 is installed on the vertical plate 9, and the output shaft of the second motor 10 is fixedly connected to the round rod 11. The second driving gear 12 is coaxially fixed on one side of the round rod 11, and the second driving gear 12 is meshed and connected with the driven gear 503, so as to realize the rotation control of the rotary joint 504 and the first exhaust duct 505. This way can separately control the rotation of the first exhaust duct 505 and the second exhaust duct 6, which is convenient for separate operation and adjustment.
