[0001] This utility model relates to the field of drying equipment technology, specifically a hot air drying device for pharmaceutical packaging printing. Background Technology

[0002] Hot air drying equipment for pharmaceutical packaging printing is a device used to dry printed packaging materials during the pharmaceutical packaging printing process. It generates hot air and blows it onto the surface of the printed packaging to accelerate the drying speed of ink or coating. This not only effectively shortens the drying time and improves production efficiency, but also ensures the clarity and quality of the printed pattern, avoiding problems such as blurred patterns and smudging caused by undried ink. This ensures the quality and safety of pharmaceutical packaging and meets the strict requirements of the pharmaceutical industry for packaging printing.

[0003] Existing hot air direct drying methods direct hot air onto the printing sheets. Before the ink has cured, it is carried away by the airflow, forming solvent-containing mist particles that are dispersed throughout the workshop with the heat. As a result, the air becomes polluted, and operators are exposed to volatile organic compounds for a long time, significantly increasing health risks. Therefore, a hot air drying device for pharmaceutical packaging printing is proposed to address the above problems. Utility Model Content

[0031] As a further implementation of this solution, the lifting assembly 2 includes an arch frame 21, an electric telescopic rod 22 is fixedly connected to the upper end of the arch frame 21, a horizontal plate 24 is fixedly connected to the bottom end of the piston rod of the electric telescopic rod 22, a guide rod 23 is fixedly connected to the upper end of the horizontal plate 24, the bottom end of the arch frame 21 is fixedly connected to the conveying device 1, and the bottom end of the horizontal plate 24 is fixedly connected to the top end of the first conical shell 31. With the above configuration, the lifting mechanism is modular, easy to maintain, and can quickly locate the drying area.

[0032] As a further implementation of this solution, the heating component 4 includes an outer cover 41, the top of which is fixedly connected to the bottom of the first conical shell 31, and a heating fixing shell 42 is fixedly connected to the bottom of the second conical shell 35.

A temperature sensor 45 is fixedly connected to the inner side of the hot air groove 43, and a lower opening 46 is provided on the lower end of the heating fixing shell 42. Through the above settings, the closed-loop temperature control ensures constant temperature drying, which can prevent the blown mist particles and hot air from being recycled, improve the consistency of ink curing, and reduce the defect rate.

[0033] As a further implementation of this solution, a gap is provided between the outer cover 41 and the heating fixing shell 42. The inner side of the annular shell 52 is fitted to the outer side of the heating fixing shell 42 through a rubber sealing ring 54, and the outer side of the annular shell 52 is fitted to the inner side of the outer cover 41 through a rubber sealing ring 54.

[0034] Workflow: When drying printed pharmaceutical packaging, the packaging is placed in the middle of the conveyor 1. The conveyor 1 transports the packaging. When the packaging is directly below the air guide assembly 3, the electric telescopic rod 22 is activated to push the horizontal plate 24 downwards. The horizontal plate 24 drives the guide rod 23 to slide inside the arch frame 21. The horizontal plate 24 then moves the entire lower part of the device downwards. When the bottom of the extension cylinder 55 is in contact with the upper end of the conveyor belt of the conveyor 1, the packaging is located inside the extension cylinder 55. The fan 34 is activated, transporting air from top to bottom. The transported air enters the hot air tank 43 from inside the second conical shell 35 and is then blown out through the lower opening 46. The heating wire 44 adds air. The temperature sensor 45 detects the temperature of the air inside the hot air tank 43, and then... The controller at the right end of the conveying device 1 controls the heating of the heating wire 44. Hot air is blown out through the lower port 46 and blown toward the pharmaceutical packaging to achieve the purpose of hot air drying. The extension tube 55 serves as a barrier for the pharmaceutical packaging. At this time, the hot air is blown out of the extension tube 55 through the air outlet 56. Since the fan 34 blows the air from top to bottom, the air around the extension tube 55 will pass through the filter port 53 and be filtered by the annular filter plate 57 before entering between the outer cover 41 and the heating fixing shell 42. The annular filter plate 57 can filter the ink in the air. The filter assembly 5 is designed to be detachable, so that the filter assembly 5 can be replaced to ensure that the filtration performance is not affected. The air between the outer cover 41 and the temperature sensor 45 then enters the interior of the connecting tube 32 through the guide hole 33, thereby achieving a circulation effect.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
