Usually there are hot air drying devices, which heat the air and then use the convection of hot air to accelerate the volatilization of the solvent in the ink. Infrared drying devices use infrared radiation to heat the surface of printed materials. Infrared rays can penetrate the ink layer and directly cause the solvent molecules and resin components in the ink to absorb energy and heat up, thereby accelerating the drying process. Ultraviolet drying devices are mainly used for drying UV inks.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0028] Example 1: In some embodiments, please refer to the accompanying drawings of the specification.

The fixed bracket 31 is fixedly installed on the inner wall of the cylinder 1, and the sliding bracket 32 ​​is fixedly installed on the end of the fixed bracket 31 away from the inner wall of the cylinder 1 by a fixing screw. The transmission shaft 33 is rotatably connected to the right side wall of the sliding bracket 32, and the extension plate 34 is fixedly installed on the end of the transmission shaft 33 away from the sliding bracket 32. A plurality of infrared bulbs 35 are fixedly installed on the extension plate 34, the elastic support assembly is installed on the left side wall of the sliding bracket 32 ​​away from the fixed bracket 31, and the linkage drive assembly is installed on the right side wall of the sliding bracket 32 ​​away from the fixed bracket 31. The screw conveyor 2 can be set as a screw conveyor produced by Xinmeixin Intelligent Equipment Co., Ltd.

[0029] The printed plates are transported from bottom to top through the screw conveyor 2. The elastic support component and the linkage drive component of the synchronous heating device 3 cooperate to make the transmission shaft 33 rotate. The rotation of the transmission shaft 33 drives the extension plate 34 to rotate. The rotation of the extension plate 34 drives the infrared bulb 35 to rotate. The infrared bulb 35 is turned on to dry the printed plates that slowly spiral up on the screw conveyor 2. The rotation of the infrared bulb 35 avoids long-term fixed-point irradiation of the infrared bulb 35, which makes the printed plates unevenly heated, which is conducive to slowly and evenly heating the printed plates.

[0030] The elastic support assembly includes: a linear bearing slider 36, an optical axis 37, a special-shaped bracket 38 and a spring 39. The two linear bearing sliders 36 are fixedly mounted on the left side wall of the sliding bracket 32 ​​away from the fixed bracket 31. Each linear bearing slider 36 is provided with an optical axis 37. The middle side of the optical axis 37 is slidably connected to the linear bearing slider 36. The special-shaped bracket 38 is fixedly mounted on the lower side of the optical axis 37. A limiting plate is fixedly mounted on the upper side of the optical axis 37. A spring 39 is provided on the lower side of each optical axis 37. The lower side of the spring 39 is in close contact with the special-shaped bracket 38, and the upper side of the spring 39 is in close contact with the linear bearing slider 36.

[0031] The linkage drive assembly includes: a rubber guide wheel 310, a first gear 311, a second gear 312, a third gear 313 and a fourth gear 314. The rubber guide wheel 310 is rotatably connected to the lower side of the special-shaped bracket 38 away from the optical axis 37 through a rotating shaft. The rubber guide wheel 310 is close to the conveying surface of the screw conveyor 2. The first gear 311 is fixedly mounted on the end of the rotating shaft of the rubber guide wheel 310 close to the inner wall of the cylinder 1. The second gear 312 is rotatably connected to the side of the special-shaped bracket 38 close to the inner wall of the cylinder 1 through a rotating shaft.

A rotating part is fixedly installed on the upper side of the rotating shaft of the second gear 312, and a spline shaft is fixedly installed on the lower side of the rotating shaft of the third gear 313. The rotating part is slidably connected to the spline shaft and rotates synchronously with the spline shaft. The fourth gear 314 is fixedly installed on one end of the transmission shaft 33 close to the inner wall of the cylinder 1, and the third gear 313 and the fourth gear 314 are meshed with each other.

[0032] When the screw conveyor 2 is started, the movement of the plate surface of the screw conveyor 2 drives the rubber guide wheel 310 of the linkage drive assembly to rotate accordingly. The rubber guide wheel 310 moves up and down while rotating. The up and down movement of the rubber guide wheel 310 drives the special-shaped bracket 38 of the elastic support assembly to move up and down, causing the spring 39 to undergo elastic deformation, so that the rubber guide wheel 310 always keeps close to the plate surface of the screw conveyor 2 while rotating.

[0033] The rotation of the rubber guide wheel 310 drives the first gear 311 to rotate, the rotation of the first gear 311 drives the second gear 312 to rotate, the rotation of the second gear 312 drives the third gear 313 to rotate, the rotation of the third gear 313 drives the fourth gear 314 to rotate, the rotation of the fourth gear 314 drives the transmission shaft 33 to rotate, the rotation of the transmission shaft 33 drives the extension plate 34 to rotate, the rotation of the extension plate 34 drives the infrared bulb 35 to rotate, the rotation of the infrared bulb 35 avoids the infrared bulb 35 from being exposed to a fixed point for a long time, resulting in uneven heating of the printed plate, and is conducive to slowly and evenly heating the printed plate multiple times.

[0034] Embodiment 2: In some embodiments, as Figure 1-Figure 7 As a preferred embodiment of the present invention, each of the rubber guide wheels 310 is provided with a baffle 4 on the side away from the inner wall of the cylinder 1. The baffle 4 is fixedly mounted on the side wall of the screw conveyor 2.

[0036] A moisture treatment device 8 is installed in the middle of the cylinder 1.

[0037] The wet gas treatment device 8 includes: an outer pipe 81, a square air inlet 82, an air outlet pipe 83 and a gas circulation component.

The gas circulation component is installed on the middle side of the outer pipe 81, and the air outlet pipe 83 is fixedly connected to the input end of the external dehumidifier.

[0038] The external dehumidifier sucks the air in the cylinder 1 into the outer pipe 81 from multiple square air inlets 82, and then enters the external dehumidifier from the outer pipe 81 through the air outlet pipe 83. The external dehumidifier removes moisture from the gas.

[0039] The gas circulation component includes: an inner pipe 84, a windshield disc 85, an air outlet 86 and a semicircular block 87. The inner pipe 84 passes through the outer pipe 81 and is fixedly installed on the middle side of the outer pipe 81. An air intake pipe is provided on the upper side of the inner pipe 84. The windshield disc 85 is fixedly installed on the lower side of the inner pipe 84. The air outlet 86 is fixedly installed on the lower side of the inner pipe 84.
