[0002] Color printing drying on the surface of carton packaging can usually be achieved by the following methods:

[0003] Natural drying: Place the printed carton in a well-ventilated environment and let it dry naturally; this method is suitable for small printing volumes or when there is ample drying time;

[0004] Forced ventilation drying: Use fans or ventilation equipment to blow air on the paper box to accelerate air circulation and help color printing dry quickly;

[0005] Heating machine drying: You can use an oven, infrared heater or other heating equipment to heat the paper box to increase the surface temperature and speed up the drying process;

[0006] UV drying: Use UV drying equipment to quickly cure and dry the ink through UV radiation;

[0007] Inkjet printing drying: For inkjet printed cartons, some inks may have quick-drying properties, or the drying process can be controlled through special inkjet printer settings; when choosing a drying method, factors such as the material of the cartons, ink type, printing process, and production efficiency need to be considered; at the same time, attention should also be paid to temperature and humidity control during the drying process to avoid deformation of the cartons, color fading, or other quality problems;

[0008] In order to ensure the drying speed and efficiency of the color printing on the surface of the carton packaging, a dryer is generally used for drying. The hot air ejected from the dryer cannot be evenly sprayed on the color printing pattern, resulting in the color printing pattern not being evenly dried. At the same time, when the drying temperature of the color printing needs to be adjusted, it is usually achieved by adjusting the power of the heating device, which consumes electricity and reduces the service life of the heating device (heating wire); Utility Model Content

[0012] Preferably, thirty-five groups of nozzles are evenly installed on the bottom of the air collecting box, and the thirty-five groups of nozzles evenly cover the upper surface of the paper box body. At the same time, the hot air ejected from the thirty-five groups of nozzles impacts the surface of the paper box body to evenly dry the color printing on the surface of the paper box body.

[0013] Preferably, two sets of guide rails are screwed and fixed on both sides of the bottom of the gantry, and two sets of guide seats are screwed and installed on both sides of the surface of the air collecting box. The guide seats are adapted to the sizes of the guide rails, and the guide seats are inserted into the inside of the guide rails.

[0014] Preferably, a dovetail-shaped guide groove is provided inside the guide track, and a dovetail-shaped guide block is fixedly provided on the guide seat, and the air collecting box is raised and lowered and limited and guided by the guide track and the guide seat.

[0015] Preferably, a screw rod is threadedly installed inside the screw-connecting cylinder, and the bottom of the screw rod is connected to the air collecting box.

[0016] Preferably, the air collecting box is driven to rise and fall by a worm gear, a screw, a screw connection tube, a driving motor and a worm, and the interior of the air collecting box is hollow.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] When the carton body is conveyed on the carton production line by the conveyor belt, the external switch of the air pump is turned on. The airflow accelerated by the air pump enters the interior of the air collecting box through the hose under the heating work of the heating wire inside the heating device, and is sprayed out from the thirty-five groups of nozzles to evenly dry the color printing on the surface of the carton body.

[0019] The air collecting box is raised and lowered and is limited and guided by guide rails and guide seats. The temperature for drying the color printing on the surface of the paper box body is controlled by adjusting the distance between the air collecting box and the paper box body. This is achieved without increasing or decreasing the power of the heating device, which is more energy-saving and can also increase the service life of the heating device.
