Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a hot air drying device for a corrugated paper box printing machine. Background Art

[0002] Corrugated paper boxes are made of corrugated cardboard through die-cutting, creasing, nailing or gluing. They are the most widely used packaging products and have always been the most used of all packaging products. In addition to protecting goods, facilitating storage and transportation, they also play a role in beautifying and promoting goods. Corrugated paper boxes are green and environmentally friendly products. They are beneficial to the environment and convenient for loading and unloading. In the production process of corrugated paper boxes, printing presses are needed to print pictures and texts on corrugated paperboards. The ink after printing cannot be cured in time, which affects the stacking and storage of paperboards and is prone to printing stains. Therefore, the printed paperboards need to be dried;

[0003] For example, the utility model patent with Chinese patent publication number CN216330844U discloses a hot air drying device for a corrugated box printing machine, comprising a workbench, a printing machine, a drying box and a fan, wherein the printing machine is fixedly mounted on one side of the upper surface of the workbench, the drying box is detachably mounted on the other side of the upper surface of the workbench, the fan is mounted on the top of the drying box, the air outlet pipe of the fan extends to the interior of the drying box and is equipped with an air outlet nozzle; a positioning groove is provided on the side of the upper surface of the workbench away from the printing machine, a bottom plate is installed at the bottom of the drying box, the bottom plate is inserted into the bottom of the inner cavity of the positioning groove and is fastened by bolts;

[0004] It was found during use of the above-mentioned prior art that the device dries the cardboard with hot air by setting a fan and an air outlet nozzle, so that the printing ink can be solidified in time, which is convenient for stacking and storing the cardboard. However, the fan directly inhales the outside air and blows the support plate dry through the air outlet nozzle. If the outside air contains impurities such as dust, it will be blocked when passing through the air outlet nozzle, or it will be blown onto the cardboard, causing stains on the cardboard printing, thereby enhancing practicality.

[0017] By adopting the above technical solution, the device can be moved, thereby enhancing practicality.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present application provides a hot air drying device for a corrugated box printing machine, which has the following beneficial effects:

[0020] Water is injected into the filter box through the water inlet hole, and the hot air blower is started. The hot air blower generates negative pressure in the filter box, and the outside air is sucked in through the air inlet pipe. The outside air enters the water in the filter box, and the dust in the air dissolves in the water. The cleaned air is filtered again through the filter net and heated by the hot air blower, and then discharged through the first air supply pipe and the second air supply pipe in turn. The printing machine body conveys the prepared cardboard to the conveyor belt, and the hot air discharged from the second air supply pipe dries the cardboard.
