Description

Technical Field

[0001] The utility model relates to the technical field of curing devices, in particular to a fluid rapid curing device for an inkjet nozzle. Background Art

[0002] An inkjet printer usually includes a printing mechanism and a curing mechanism. The nozzle in the printing mechanism is used to print ink onto a horizontal substrate, while the curing lamp in the curing mechanism is used to solidify the ink on the substrate to prevent the ink from spreading on the surface of the substrate and affecting the printing effect.

[0003] When the curing mechanism is slightly far from the printing mechanism, the ink will spread on the substrate, resulting in poor printing effect; but when the curing mechanism and the printing mechanism are close, the light of the curing lamp will directly or indirectly hit the nozzle through reflection, which will cause the nozzle to be easily cured, affecting the subsequent use of the nozzle. Therefore, the present application provides a fluid rapid curing device for inkjet nozzles to meet the needs. Utility Model Content

[0028] like Figure 1-4As shown, an embodiment of the utility model provides a fluid rapid curing device for an inkjet nozzle, comprising a mounting shell 1 and a plurality of nozzle bodies 2 mounted inside the mounting shell 1, a support ring 3 being fixedly mounted on the outer wall of the nozzle body 2 near the lower surface, a mounting groove 4 being provided inside the mounting shell 1, a connecting shaft 5 being provided inside the mounting groove 4, limiting blocks 6 being fixedly mounted on both ends of the connecting shaft 5, limiting grooves 7 for slidingly cooperating with the limiting blocks 6 being provided on the inner walls on both sides of the supporting ring 3, a plurality of connecting sleeves 8 being rotatably connected to the outer wall of the connecting shaft 5, a movable groove 14 being provided on one side of the mounting shell 1, a bending plate 9 being fixedly mounted on one side of the plurality of connecting sleeves 8, one end of the bending plate 9 passing through the movable groove 14, and a bending plate 9 being provided on the other end. A bending portion 10, a UV lamp tube 11 is fixedly installed on one side of the bending portion 10, a contact plate 12 is fixedly installed on the other side of the bending portion 10, one side of the contact plate 12 is in contact with the top of the support ring 3, multiple groups of springs 15 are fixedly installed on the bottom of the connecting shaft 5, one end of the spring 15 is fixedly connected to the inner wall of the mounting shell 1, a limiting plate 13 is fixedly installed on one side of the bending portion 10, the limiting plate 13 is arranged above the contact plate 12, multiple groups of connecting sleeves 8 are equidistantly arranged, multiple groups of moving grooves 14 are equidistantly arranged, multiple groups of springs 15 are equidistantly arranged, the spring 15 is arranged between two adjacent groups of connecting sleeves 8, one side of the limiting plate 13 is in contact with one side of the nozzle body 2, and a circular chamfer is provided on one side of the bending portion 10.

[0029] The device is installed inside the inkjet printer. When using inkjet printing, the multiple groups of springs 15 are in the initial extension state, the connecting shaft 5 and the connecting sleeve 8 are located at the top of one side of the moving groove 14, and the limit block 6 is at the top position of the limit groove 7. At this time, the contact plate 12 is placed on the top of the support ring 3. When the nozzle body 2 performs inkjet printing on the paper surface, the ultraviolet lamp 11 is started. By setting the ultraviolet lamp 11 close to the nozzle body 2, the printed part is irradiated and cured in time, which accelerates the drying and curing of the ink on the medium and avoids the ink from drying and curing. The diffusion of water improves the printing quality. By setting the bending part 10, the ultraviolet lamp tube 11 and the nozzle body 2 are blocked, so that the light emitted by the ultraviolet lamp tube 11 is diverged along the side of the bending part 10 away from the nozzle body 2, preventing the ultraviolet lamp tube 11 from emitting light to solidify the ejection end of the nozzle body 2, ensuring that the nozzle body 2 can work stably. When the nozzle body 2 is not working, first turn the connecting sleeve 8 and the bending plate 9 to one side to separate the abutment plate 12 from the support ring 3, and then pull the bending plate 9 downward to make the connecting sleeve 8 with The movable connecting shaft 5 moves downward, so the limit block 6 moves vertically downward along the limit groove 7. The connecting shaft 5 squeezes the spring 15 while moving downward. When the connecting sleeve 8 moves to the lower end position of the mounting shell 1, the bending plate 9 is turned toward one side of the nozzle body 2, so that one side of the bending plate 9 and the bottom of the nozzle body 2 are in conflict with each other. Since the limit plate 13 has the property of elastic deformation, one end of the limit plate 13 is placed on the top of the support ring 3. Since the multiple groups of springs 15 provide an upward thrust, the bending plate 9 is stabilized at the bottom of the nozzle body 2. The output end is covered to effectively prevent dust, impurities, etc. from entering the nozzle body 2, keep the nozzle body 2 clean, reduce the occurrence of blockage and failure, and prevent the ink from drying quickly on the surface of the nozzle body 2 to avoid clogging the nozzle hole of the nozzle body 2. The connecting sleeve 8, the movable groove 14 and the spring 15 are equidistantly arranged, and the movable groove 14 cooperates with the vertical movement of the connecting sleeve 8 and one end of the bending plate 9, and the spring 15 is evenly distributed to provide a stable and average thrust, so that the bending plate 9 is convenient to be turned over and fixed to the bottom of the nozzle body 2 to cover it.

[0030] The utility model provides a technical solution, the device is installed inside the inkjet printer, when using inkjet printing, the multiple groups of springs 15 are in the initial extension state, the connecting shaft 5 and the connecting sleeve 8 are located at the top of one side of the moving groove 14, the limit block 6 is at the top position of the limit groove 7, the contact plate 12 is placed on the top of the support ring 3, the nozzle body 2 is performing inkjet printing on the paper surface, and the ultraviolet lamp 11 is started, the ultraviolet lamp 11 irradiates and cures the printed part in time, the bending part 10 blocks the ultraviolet lamp 11 and the nozzle body 2, so that the light emitted by the ultraviolet lamp 11 is diverged along the side of the bending part 10 away from the nozzle body 2, and when the nozzle body 2 is not working, it first goes to one side. The connecting sleeve 8 and the bending plate 9 are rotated sideways to disengage the contact plate 12 from the supporting ring 3, and then the bending plate 9 is pulled downward, so that the connecting sleeve 8 drives the connecting shaft 5 to move downward, so that the limiting block 6 moves vertically downward along the limiting groove 7, and the connecting shaft 5 squeezes the spring 15 while moving downward. When the connecting sleeve 8 moves to the lower end position of the mounting shell 1, the bending plate 9 is flipped toward the side of the nozzle body 2, so that one side of the bending plate 9 is in conflict with the bottom of the nozzle body 2. Since the limiting plate 13 has the property of elastic deformation, one end of the limiting plate 13 is placed on the top of the supporting ring 3. Since the multiple sets of springs 15 provide upward thrust, the bending plate 9 is stabilized at the bottom of the nozzle body 2 to cover the output end.
