Abstract
Description
Technical Field
[0001] The utility model relates to the field of UV flatbed printers, and specifically to a deviation rectifying mechanism for a UV flatbed printer. Background Technique
[0002] A UV flatbed printer is a printing device that adopts piezoelectric inkjet technology. It combines UV photosensitive technology and realizes the printing effect through computer input control, using inkjet technology and UV curing technology; the UV flatbed printer can print on various materials.
[0003] The printing principle of a UV flatbed printer is to rely on the voltage inside the print head to eject the UV ink in the nozzle holes onto the surface of the printing substrate; the print head can precisely control the ink output of the nozzle holes. At the same time, the ultraviolet waves emitted by the UV lamp react with the photosensitive curing agent in the UV ink, causing the pigment molecules in the ink to quickly cure on the surface of the material, realizing the rapid drying of the ink without the need for traditional baking or drying procedures.
[0004] Existing UV flatbed printers generally directly transport the paper to the input end. During use and observation, it is found that the paper will shift during transportation, and the shifted paper will be difficult to accurately feed into the printing area, which will cause paper jams in the UV flatbed printer.
[0005] Therefore, in view of the above problems, a deviation rectifying mechanism for a UV flatbed printer is proposed. Content of the Utility Model

When the paper is transported, it will pass through between a pair of clamping plates 16. If the paper is offset during transportation, one side of it will contact the clamping plate 16, and then the offset paper will be reset under the extrusion of the clamping plate 16. At the same time, the paper will also contact the buffer component 17, and the buffer component 17 will also extrude the paper and slow down the speed of the paper. When the device corrects the deviation of papers of different sizes during feeding, the motor 12 can be started to make the cam 13 rotate. When the cam 13 rotates, the connecting block 14 will move together.

When the paper is transmitted, the top will come into contact with the pressure wheel 4 and cause the pressure wheel 4 to rotate under the action of friction. The pressure wheel 4 will squeeze and flatten the surface of the paper, reducing the wrinkles on the surface of the paper and improving the flatness of the surface of the paper.
[0030] Please refer to Figure 4 and Figure 5As shown, a trachea 5 is connected to the top of the connecting shaft 42 on one side; the connecting shaft 42 and the pressing wheel 4 are in a communicating relationship; a plurality of circular holes 52 are formed in the middle of the pressing wheel 4; during operation, the trachea 5 can be externally connected to an exhaust fan.

[0033] Working principle: Install the device on one side of the input end of the UV flatbed printer, and then the paper can be transported. When the paper is transported, it will pass through a pair of clamping plates 16. If the paper deviates during transportation, one side of the paper will contact the clamping plate 16, and then the deviated paper will be reset under the extrusion of the clamping plate 16. At the same time, the paper will also contact the buffer component 17, and the buffer component 17 will also extrude the paper and slow down the speed of the paper. When the device corrects the deviation of papers of different sizes during feeding, the motor 12 can be started to make the cam 13 rotate. When the cam 13 rotates, the connecting block 14 will move together. When the connecting block 14 moves, the angle of the connecting rod 15 will change, and the connecting rod 15 will apply a force to the clamping plate 16 to make it slide along the support base 1, realizing the adjustment of the distance between a pair of clamping plates 16; when the paper deviates, it will contact the rotating wheel 23, and the rotating wheel 23 will be extruded by the paper and make the connecting frame 24 and the sliding rod 2 slide along the clamping plate 16. When the sliding rod 2 slides, the elastic spring 22 will be in a stretched state, so that there will be a buffer space when the deviated paper contacts the clamping plate 16. Then the elastic spring 22 will apply an elastic force to the sliding rod 2 and the connecting frame 24, so that the rotating wheel 23 will extrude the paper under the action of the elastic force, enhancing the extrusion and deviation correction effect of the device on the paper. At the same time, the rotating wheel 23 will also rotate under the action of friction, converting the sliding friction between the paper and the clamping plate 16 into rolling friction; when the paper contacts the rotating wheel 23, the sponge 3 will also contact the side wall of the paper, and the sponge 3 will remove the impurities attached to the side wall of the paper, realizing the cleaning of the paper by the device; when adjusting the distance between a pair of clamping plates 16, the spring telescopic rod 43 will be in a stretched state. When the paper is transported, the top of the paper will contact the pressing wheel 4 and make the pressing wheel 4 rotate under the action of friction. The pressing wheel 4 will extrude and flatten the surface of the paper, reducing the wrinkles on the surface of the paper; during operation, the air pipe 5 can be externally connected to an exhaust fan. After the exhaust fan is started, the air flow in the connecting shaft 42 will flow out through the air pipe 5. At the same time, the air flow at the round hole 52 will enter the inside of the pressing wheel 4 and then enter the inside of the air pipe 5 through the connecting shaft 42. At this time, the impurities on the top of the paper will be removed under the suction of the air flow; the pressing block 62 will make the telescopic rod 6 in the maximum stretched state under the action of gravity.
