[0002] The UV flatbed printer adopts piezoelectric inkjet printing technology. It does not directly contact the surface of the material. Relying on the voltage inside the print head, the ink in the nozzles is ejected onto the surface of the substrate to achieve the purpose of printing pictures. During the printing process, the ultraviolet wave emitted by the LED cold light source lamp reacts with the photosensitive curing agent in the UV ink, causing the pigment molecules in the UV ink to be cured on the surface of the material, realizing the drying of the ink, and providing customers with the convenient service of getting the printed works immediately.
[0003] However, for the existing UV printers, during use, since there is a large amount of ink inside the print head, after use, the residual ink inside the print head will solidify inside the print head, resulting in the blockage of the print head, affecting the service life of the print head, and the print head needs to be cleaned regularly, which affects the use efficiency of the printer.

Specific embodiments
[0018] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0019] See Figures 1 to 4 , the present utility model provides a waste ink recovery device, which includes a nozzle body 1 with an ink channel inside. Ink is supplied to the nozzle outlet through the ink channel to ensure the printing effect. A recovery channel 2 communicating with the ink channel is provided on the side wall of the nozzle body 1. The residual ink inside the nozzle is recovered through the recovery channel 2 to ensure the cleanliness inside the nozzle and reduce the waste of materials at the same time; a plugging head 6 slidably connected inside the ink channel is used to control the on-off of the ink channel. After printing is completed, the nozzle is plugged by the plugging head 6 to prevent the internal ink from dripping and affecting the printing effect. A cleaning part is provided at the front end of the plugging head 6. The cleaning part is connected to the plugging head 6 and is rotatably connected in the rotating hole 63 on the plugging head 6. When the plugging head 6 plugs the ink channel, the cleaning part guides the ink inside the ink channel into the recovery channel 2. After the nozzle is used up, the cleaning part can adsorb the material into the recovery channel 2 under the suction of the recovery channel 2, and then the cleaning part can rotate under the action of the adsorption force and the reaction force of the flowing liquid and gas, so as to clean the inner wall of the nozzle body 1.
[0020] Preferably, a sealing bevel edge 12 is provided inside the ink channel of the present utility model. The plugging head 6 is provided with a sealing portion 64 that cooperates with the sealing bevel edge 12. By the inclined surface of the sealing portion 64 being attached to the sealing bevel edge 12, the ink channel is plugged to prevent ink from leaking from the inside of the ink channel. A plurality of communication channels 61 are provided on the plugging head 6. When the plugging head 6 is separated from the sealing bevel edge 12, the communication channels 61 communicate the two ends of the plugging head 6. At this time, the ink can be discharged from the water spraying outlet 3 of the nozzle body 1 through the communication channels 61 to realize the printing process.
[0021] In addition, an annular groove 13 is provided on the inner wall of the ink channel of the present utility model. An annular protrusion 65 that is slidably connected to the inside of the annular groove 13 is provided on the outer wall of the plugging head 6. By the cooperation of the annular protrusion 65 and the annular groove 13, the sliding distance of the plugging head 6 is limited. A thrust spring 62 that presses the plugging head 6 against the sealing bevel edge 12 is provided between the annular protrusion 65 and the annular groove 13. It is ensured that when the nozzle is not working, the plugging head 6 can be abutted against the sealing bevel edge 12 under the action of the thrust spring 62, thereby plugging the ink channel.
[0022] Furthermore, a plurality of plugging columns 11 that cooperate with the communication channels 61 are provided on the sealing bevel edge 12 of the present utility model. After the plugging head 6 plugs the recovery channel 2, the plugging columns 11 are withdrawn from the inside of the communication channels 61. By providing the cooperation of the plugging columns 11 and the communication channels 61, it is ensured that when the plugging head 6 plugs the recovery channel 2, the communication channels 61 will only communicate the ink channel, further preventing the ink at the water inlet end of the ink channel from entering the inside of the recovery channel 2 under the action of negative pressure.
[0023] Better, the cleaning member of the present utility model includes a rotating shaft 5 rotatably connected to the plugging head 6 and a spiral blade 4 fixed to the rotating shaft 5, ensuring that the spiral blade 4 can rotate under the reaction force of the flow force. The outside of the spiral blade 4 is closely attached to the inner wall of the ink channel, ensuring that the spiral blade 4 can clean the inner wall of the ink channel. The ink channel is provided with a nozzle outlet. An electromagnetic valve is provided inside the recovery channel 2. Negative pressure is supplied inside the recovery channel 2, ensuring that the residual ink inside the nozzle body 1 can be sucked out through the opening and closing of the recovery channel 2 and by negative pressure, ensuring the cleanliness inside the nozzle body 1.
[0024] In this embodiment, in combination with Figures 1 to 4, during use, when printing is required, ink is supplied to the inlet of the nozzle body 1. At this time, under the pressure of the ink, the plugging head 6 is pushed to move until the plugging column 11 of the plugging head 6 is withdrawn. At this time, the plugging head 6 plugs the recovery channel 2, and the ink is discharged through the outlet of the nozzle body 1 for printing. After printing is completed, ink is no longer supplied to the inlet at this time. The plugging head 6 resets under the action of the thrust spring 62 and plugs the ink channel. Then the solenoid valve is opened, and negative pressure is supplied to the recovery channel 2 to suck out the residual ink inside the nozzle body 1. And under the suction force, the flow of air and liquid drives the spiral blade 4 to rotate, cleaning the inner wall of the ink channel.
[0025] In summary, the present invention provides a waste ink recovery device, including: a nozzle body, which is internally provided with an ink channel for supplying ink to the nozzle outlet to ensure the printing effect. A recovery channel communicating with the ink channel is provided on the side wall of the nozzle body to recover the residual ink inside the nozzle through the recovery channel, ensuring the cleanliness inside the nozzle and reducing the waste of materials at the same time; a plugging head slidably connected inside the ink channel, which controls the on-off of the ink channel through the plugging head to ensure that the nozzle is plugged by the plugging head after printing is completed to prevent the internal ink from dripping and affecting the printing effect. A cleaning member is provided at the front end of the plugging head, and the cleaning member is connected to the plugging head. When the plugging head plugs the ink channel, the cleaning member guides the ink inside the ink channel into the inside of the recovery channel, ensuring that after the nozzle is used, the cleaning member can adsorb the material into the inside of the recovery channel under the suction force of the recovery channel. Then the cleaning member can rotate under the action of the adsorption force and the reaction force of the flowing liquid and gas, thereby cleaning the inner wall of the nozzle body. In summary, the technical effect produced by the present invention is to provide a structure that can recover the residual ink inside the nozzle, ensuring that after the nozzle is used, the ink inside the nozzle is recovered, reducing the ink residue inside the nozzle, and increasing the service life of the nozzle.
