Description

Technical Field

[0001] The utility model relates to the technical field of printing and drying, in particular to a printing ink drying device. Background Art

[0002] In the prior art, printing is a technology that transfers the original manuscripts such as characters, pictures, photos, anti-counterfeiting, etc. to the surfaces of materials such as paper, textiles, and leather through processes such as plate making, inking, and pressing, and batch-replicates the content of the original manuscripts. Printing is a process of transferring special inks to the printing substrates through printing machines. The printing of packaging shells is usually carried out when the packaging shells are made of cardboard. After printing, the packaging shells need to be cut. The formed single packaging shells can be stacked and stored. Therefore, it is necessary to quickly dry the printing ink before cutting the packaging shells.

[0003] After retrieval, a patent with the Chinese patent application number 202321573449.8 discloses a printing ink drying device, including a drying conveyor rack. The number of the drying conveyor racks is two. Two connecting racks are fixedly connected between the two drying conveyor racks. The two connecting racks are symmetrically distributed with the axis of the drying conveyor rack as the center. A drying box is arranged on the top of the two drying conveyor racks. Two transmission drums are rotatably sleeved inside the drying conveyor rack. The two transmission drums are symmetrically distributed with the axis of the drying conveyor rack as the center. There is a drying equipment assembly inside the drying box. An extended drying assembly is arranged between the two drying conveyor racks.

[0004] The above patent has the following deficiencies: The device fixedly installs a drying box on both sides of the two drying conveyor racks through fixed support plates. Secondly, two transmission drums are rotatably sleeved between the two drying conveyor racks through support rotating rods, so as to roll and support the printing paper. Cooperating with the drying heating rods arranged inside the drying box and the air drying fans fixedly sleeved inside the drying box, the hot air of the drying heating rods is circulated, so as to dry the printing paper. However, in the actual use process, the air flow circulation effect generated by the air drying fans is relatively weak. A large amount of hot air will diffuse to the outside from both sides of the bottom of the drying box, reducing the drying effect. At the same time, the drying heating rods are too close to the paper, and the heat has a greater impact on the paper. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a printing ink drying device.

[0039] Working principle:

[0040] Please refer to Figures 1 to 4 , and assemble this device as shown in the figure;

[0041] Synchronously start the drive motor 6 and the diversion fan 13, and energize the electric heating grid plate 11 for heating; the packaging shell cardboard 3 moves along with the conveyor belt 2, enters the interior of the protective cover shell 7 from one end where the rotating baffle 9 is installed on the protective cover shell 7, and leaves the protective cover shell 7 from the other end; when the packaging shell cardboard 3 enters the interior of the protective cover shell 7, the diversion fan 13 circulates and diverts the air inside the protective cover shell 7. After the flowing air passes through the electric heating grid plate 11, under the action of the first flow blocking baffle 16 and the second flow blocking baffle 17, it blows towards the ink printing surface of the packaging shell cardboard 3, and the diversion bending plate 15 further squeezes the air flow towards the packaging shell cardboard 3 to accelerate the ink drying effect; the air passing through the convex points under the diversion bending plate 15, under the action of the shunt connecting plate 26, the third flow blocking baffle 28 and the fourth flow blocking baffle 29, flows back into the gap between the outer wall of the diversion ring frame 14 and the top inner wall of the protective cover shell 7, then passes through the through-flow installation box 24, is dried by the air drying plate 25, and is then introduced into the heated circulating air flow again by the diversion fan 13 to dry the ink printing surface of the packaging shell cardboard 3;

[0042] In the above process, there is a small amount of hot air escaping through both ends of the protective cover shell 7 and the gap of the conveyor belt 2 in the circulating heated air. Therefore, the width of the conveyor belt 2 should be greater than the width of the packaging shell cardboard 3. By adjusting the deflection angle of the rotating baffle 9 through the cooperation of the connecting slide rod 19 and the extrusion bolt 22, the heat dissipation speed at the front end of the protective cover shell 7 is reduced; at the same time, the negative pressure flow channel 8 is cooperated to extract air from the outside and supplement it into the circulating air flow. And the air inlet of the illustrated negative pressure flow channel 8 is arranged at the top of the packaging shell cardboard 3. The air entering the negative pressure flow channel 8 will absorb the heat dissipated from the dried packaging shell cardboard 3 to accelerate the cooling speed of the packaging shell cardboard 3.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
