[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1-4 As shown, a drying mechanism and a printing machine include an introduction roller 2 rotatably arranged on an installation cabin 1 and an output roller 3 arranged above the installation cabin 1;

[0028] A heating chamber 4 with electric heating wires is arranged in the installation chamber 1;

[0029] The installation cabin 1 is symmetrically provided with an inclined surface 11 on one side relative to the introduction rod 2, and a plurality of blowing nozzles 5 arranged in a linear array are provided on the inclined surface 11 above the introduction rod 2, and a plurality of suction nozzles 6 arranged in a linear array are provided on the inclined surface 11 below the introduction rod 2;

[0030] The output end of the heating chamber 4 is communicated with the air inlet of the suction nozzle 6 .

[0031] Specifically, the heating chamber 4 in the embodiment is directly connected to the mains 220V, the temperature is operated at 45°C-55°C, and the temperature sensor monitors the temperature in the heating chamber 4, thereby achieving temperature control operation. The electronic components and control programs in the above embodiments are well known to those skilled in the art, so they are not described in detail.

[0032] In the above technology, when the fan in the heating chamber 4 is running, the running heat is blown out from the blowing nozzle 5. Since the air outlet of the blowing nozzle 5 is facing the installation chamber 1 and the introduction rod 2, the heat will enter the installation chamber 1 along the curved surface of the introduction rod 2, and then be sucked back into the heating chamber 4 by the suction nozzle 6 for secondary heating, thereby achieving drying of the printed paper.

[0033] As an embodiment further provided by the present invention, the air outlet of the blowing nozzle 5 is a rounded rectangular structure, and the air outlet faces the curved surface of the introduction rod 2 .

[0034] Specifically, the combination of the embodiments Figure 4 It can be seen that the air outlet of the blowing nozzle 5 in the embodiment is a rounded rectangular structure, so that the blown hot air is diffused in a fan shape, thereby slowing down the flow rate of the hot air blown out of the blowing nozzle 5, avoiding high-speed downward blowing so that the printing ink is blown away by the airflow.

[0035] As another embodiment further provided by the utility model, a first arc plate 7 arranged close to the outlet rod 3 is fixedly installed on the installation cabin 1, and a plurality of guide grooves 71 arranged in a linear array are opened on one side of the first arc plate 7.

[0036] Furthermore, the guide groove 71 is divided into a wide-mouth portion and a narrow-mouth portion according to the structure. The wide-mouth portion is arranged close to the blowing nozzle 5, and the narrow-mouth portion is located at one-half of the arc surface of the first arc plate 7. The other half of the arc surface of the first arc plate 7 is provided with a plurality of long rectangular grooves 72 arranged in a matrix.

[0037] Specifically, the first curved plate 7 in the embodiment is an aluminum alloy plate. When heat enters the installation chamber 1 along the curved surface of the introduction rod 2, it is introduced from the wide mouth and then discharged from the narrow mouth, thereby accelerating the flow of air and increasing the temperature of the first curved plate 7, thereby assisting in drying.

[0038] As another embodiment further provided by the utility model, a second curved plate 8 (cast iron part) arranged close to the first curved plate 7 is fixedly installed on the installation cabin 1, and an extension portion 81 extending from each long rectangular groove 72 to close to the first curved plate 7 is provided on the second curved plate 8.

[0039] Furthermore, the extension portion 81 is divided into a connecting portion 811 , a horizontal portion 812 and an inclined portion 813 according to the structure, and the three are arranged in an isosceles trapezoidal structure, and the inclined portion 813 is not connected to the second arc-shaped plate 8 .

[0040] Furthermore, a groove 82 is formed on the second arc plate 8 , and the connecting portion 811 is connected to a first end of the groove 82 .

[0041] Specifically, in the embodiment, a temperature chamber is formed because a predetermined interval is maintained between the second curved plate 8 and the first curved plate 7. Thus, the second curved plate 8 and the first curved plate 7 exchange heat, so that the first curved plate 7 and the second curved plate 8 are heated at the same time, so as to ensure that the temperature of the first curved plate 7 remains constant.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
