[0002] After inkjet printing is performed on materials, the time it takes for the ink on the surface of the printed material to solidify varies depending on the material of the printed material. When the ink on the surface of the material is not completely solidified, the ink on the surface is easily contaminated, rubbed off, or even contaminated to other products when the material is collected. Therefore, after the ink is printed on the material, a curing lamp is required to accelerate the solidification of the ink. However, the temperature generated during the operation of the curing lamp is too high, which reduces its service life and easily makes the ambient temperature too high, causing certain damage to the material and affecting the operation of the inkjet printing equipment.

Baffles 207 are also fixedly installed on both sides of the center line of the outer wall of the conveying cylinder 202.

[0077] The setting of the avoidance groove 301 ensures that the ink absorbing roller 603 can move up and down normally, and ensures that the ink absorbing roller 603 can absorb the ink on the printed materials of different thicknesses. The setting of the baffle 207 can serve the purpose of positioning the printed material, preventing the printed material from deviating from the track when curing the ink, affecting the normal curing of the ink on the printed material.

[0078] As an optimization solution of the present invention, Figure 4 As shown, it also includes a guide plate 9 and a blanking plate 13. The guide plate 9 is installed on the inner wall of the curing box 3 at an angle upward, and the lower end of the guide plate 9 is located below the feed port 7. The blanking plate 13 is arranged below the conveying cylinder 202. The blanking plate 13 slides with the outer wall of the conveying cylinder 202, and the blanking plate 13 is fixedly installed on the inner wall of the curing box 3.

[0079] The setting of the guide plate 9 facilitates the conveying of the printed matter to be cured to the conveying tube 202 in the curing box 3, and the setting of the unloading plate 13 facilitates the removal of the printed matter from the outer wall of the conveying tube 202, ensuring the normal unloading of the printed matter and improving the curing efficiency and curing quality of the printed matter.

[0080] The working process is as follows:

[0081] The printed matter that needs to be cured ink is input from the feed port 7 into the interior of the curing box 3, the motor 208 is turned on to drive the driving wheel 209 to rotate, the driving wheel 209 rotates to drive the driven wheel to rotate, the driven wheel 2015 rotates to drive the rotating shaft 2017 to rotate, the rotating shaft 2017 rotates to drive the material-dispensing rod 2010 to rotate around the rotating shaft 2017, the material-dispensing rod 2010 rotates to drive the material-dispensing column 2014 to rotate, and the material-dispensing column 2014 cooperates with the limiting groove 2012 on the fixed disk 2011 during the rotation process, thereby driving the fixed disk 2011 to rotate around the rotating shaft 203, and the rotating shaft 203 drives the connecting rod 204 to rotate, and the connecting rod 204 is connected to the fixed disk 2011. The connecting rod 204 rotates to drive the conveying cylinder 202 to rotate. The rotation of the conveying cylinder 202 can drive the printed matter that needs to be cured to rotate along with the rotating shaft 203. When the printed matter reaches the bottom of the conveying cylinder 202, under the action of the annular limiting plate 10, the limiting rod 803 is driven up and down, and the limiting rod 803 can also be driven to rotate. The lifting and lowering and rotating of the limiting rod 803 can also drive the lower pressure rod 802 to lift and rotate. The lifting and lowering of the lower pressure rod 802 will release the restriction on the printed matter. Under the action of the unloading plate 13, the printed matter is scraped off the conveying cylinder 202, and the printed matter with the ink cured is discharged from the discharge port 11.

[0082] When the printed product is conveyed to the outer wall of the conveying cylinder 202, the limiting rod 803 on the lower pressing member 8 comes down from the annular limiting plate 10, so that the lower pressing rod 802 fixes the printed product with ink that needs to be cured on the outer wall of the conveying cylinder 202. Continuing to rotate the conveying cylinder 202 will drive the printed product to rotate along the rotating shaft 203. During the rotation of the conveying cylinder 202, the exhaust fan 12 is turned on. When the exhaust fan 12 is turned on, the air in the curing box 3 is extracted from the air in the curing box 3, and the air is conveyed from the air inlet chamber 4 to the curing box 3, thereby accelerating the air flow rate inside the curing box 3, curing the ink on the printed product that needs to be cured, and greatly improving the efficiency and quality of ink curing.

[0083] The above contents are merely examples and explanations of the structure of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the scope defined by the structure of the present invention, they shall all fall within the protection scope of the present invention.
