Description

Technical Field

[0001] The utility model belongs to the technical field of inkjet printing, in particular to a double-station rotary printing device. Background Art

[0002] Inkjet technology is a method for precisely depositing liquid droplets in very thin layers. It was originally developed for the publishing industry, enabling text and graphics, but has become a popular method for the digital fabrication of electronic and mechanical devices. Although the terms "jetting," "inkjet technology," and "inkjet printing" are often used interchangeably, inkjet printing typically refers to the publishing industry's use for printing graphic content, while jetting generally refers to general manufacturing through particle deposition.

[0003] However, there are some problems with the existing technology: most of the existing inkjet machines can only print in parallel sliding and do not have the function of inkjet printing on curved objects. The functions of such inkjet machines are too single. At the same time, the existing inkjet machines only have one printing platform. After printing an object, reloading and reprinting are required, which is time-consuming. Therefore, we propose a dual-station rotary printing device. Utility Model Content

[0004] In response to the problems existing in the prior art, the purpose of the present utility model is to provide a double-station rotary printing device, which drives the fixed plate to rotate through the turntable assembly, and drives the clamping assembly on the fixed plate to rotate. When the printed object is a curved surface, the first rotating motor rotates the clamping assembly to make the printed object parallel to the print nozzle on the printing mold, ensuring that the ink droplets are evenly dripped on every part of the printed object and that the ink droplets are vertically dripped on the fixed plate. At the same time, two turntable assemblies and clamping assemblies are arranged on the workbench, thereby achieving the same scene and effect as conventional printing, and realizing double-station printing at the same time. When printing is carried out on this side, the material is loaded on the other side, thus achieving the effect of alternating loading and transmission.

[0005] The utility model is implemented as follows: a double-station rotary printing device comprises: two support frames, workbenches are fixedly mounted on the upper surfaces of the two support frames, two fixed frames are fixedly mounted on the upper surfaces of the workbenches, guide rails are fixedly mounted on the two fixed frames, a driving rod is mounted on the fixed frame, a sliding plate is slidably connected to the guide rail, the driving rod drives the sliding plate to slide along the guide rail, a turntable assembly is fixedly mounted on the sliding plate, a fixed plate is fixedly mounted on the turntable assembly, and two clamping assemblies are fixedly mounted on the surface of the fixed plate.

[0006] Optionally, a moving block is slidably connected to the driving rod, the sliding plate is fixedly installed on the upper surface of the moving block, and sliding grooves are provided at both ends of the lower surface of the moving block.

[0029] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0030] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 6 As shown, an embodiment of the present invention provides a double-station rotary printing device, comprising: two support frames 1, the two support frames 1 are U-shaped and are used to fix a workbench 2 at the upper end for operation, the workbench 2 is fixedly installed on the upper surface of the two support frames 1, and two fixing frames 6 are fixedly installed on the upper surface of the workbench 2, the two fixing frames 6 are respectively located at both ends of the upper surface, and the two fixing frames 6 extend from one side of the workbench 2 to the other side, so that the sliding plate 20 can slide from one side of the workbench 2 to the other side.

[0032] The two fixed frames 6 are fixedly mounted with guide rails 7, the fixed frames 6 are mounted with driving rods 8, the guide rails 7 are slidably connected with sliding plates 20, the driving rods 8 drive the sliding plates 20 to slide along the guide rails 7, the sliding plates 20 are fixedly mounted with turntable components 3, the turntable components 3 are fixedly mounted with fixed plates 19, two clamping components 4 are fixedly mounted on the surface of the fixed plates 19, the driving rods 8 on the guide rails 7 drive the sliding plates 20 to slide, so that the turntable components 3 and the clamping components 4 can slide to each working position for operation, the turntable components 3 drive the fixed plates 19 to rotate, thereby rotating the clamping components 4 on the fixed plates 19, and then the clamping components 4 clamp the items to be printed, driving the printed items to rotate, thereby ensuring that the ink droplets are evenly dropped on every part of the printed object.

[0033] Specifically, the driving rod 8 is fixedly installed on the middle end of the upper surface of the guide rail 7, and a moving block 17 is slidably connected to the driving rod 8. The sliding plate 20 is fixedly installed on the upper surface of the moving block 17. Slide grooves are provided at both ends of the lower surface of the moving block 17. The slide grooves are slidably connected to the slider on the guide rail 7. After the driving rod 8 is started, it drives the moving block 17 to slide back and forth. The driving rod 8 passes through the slide groove and drives the moving block 17 to move.

[0034] Specifically, a plurality of support columns 16 are fixedly installed on the middle end of the upper surface of the sliding plate 20, and a turntable assembly 3 is fixedly installed on the upper ends of the plurality of support columns 16. The turntable assembly 3 includes a chute plate 301, and the chute plate 301 is fixedly installed on the upper ends of the plurality of support columns 16. An annular chute 305 is provided on the surface of the chute plate 301. The chute plate 301 is used to fix the rotating plate 302 on its surface. When the rotating plate 302 is driven, the pulley 303 on the chute plate 301 will drive the rotating plate 302 to rotate in a circular manner, repeatedly rotating clockwise or counterclockwise.

[0035] Specifically, multiple pulleys 303 are slidingly connected in the annular groove 305. The sliding connection between the groove plate 301 and the multiple pulleys 303 enables the rotating disk 302 to slide smoothly on the upper ends of the multiple pulleys 303. The upper surfaces of the multiple pulleys 303 are fixedly connected to the rotating disk 302. The lower surface of the rotating disk 302 has multiple bevel gear blocks 304 in an annular array, and the second rotating motor 9 is meshed and connected to the bevel gear blocks 304.

[0036] To be more specific, the second rotating motor 9 includes a second motor 901, which is fixedly mounted on one end of the sliding plate 20. A bevel gear 902 is fixedly mounted on the output end of the second motor 901. The bevel gear 902 is meshed with the bevel gear block 304. When the output end of the second rotating motor 9 rotates, the bevel gear 902 rotates, and then the bevel gear 902 drives the rotating disk 302 to rotate. The bevel gear block 304 on the bevel gear 902 pushes the bevel gear block 304 on the rotating disk 302. After the rotating disk 302 rotates, the components on the rotating disk 302 can be evenly sprayed with ink.

[0037] Preferably, the two clamping assemblies 4 include two placement racks 401, and the two placement racks 401 are respectively fixedly installed at the two ends of the upper surface of the fixed plate 19. One end of the placement rack 401 is circularly arranged, and a circular groove 18 is opened on the placement rack 401. A bevel gear plate 402 is rotatably connected in the circular groove 18. The inner surface of the bevel gear plate 402 is arranged with multiple clamping rods 403 in a circular array, and a through hole is opened on one side of one of the placement racks 401.

[0038] To be more specific, the surface of the beveled gear disc 402 is rotatably connected to a first rotating motor 5, and the first rotating motor 5 includes a first motor 501, which is fixedly mounted on one end of the fixed plate 19, and a beveled gear column 502 is fixedly mounted on the output end of the first motor 501, and the beveled gear column 502 passes through a through hole provided on one side of one of the placement racks 401 and is engaged with the beveled gear disc 402. The object to be inkjetted is placed in the placement rack 401, and then the three clamping rods 403 clamp the object, and then the first motor 501 rotates to rotate the beveled gear column 502, and then the beveled gear column 502 drives the beveled gear disc 402 to rotate, thereby driving the object clamped by the clamping rod 403 to rotate, so that the object can be evenly sprayed with ink to every position.

[0039] In further detail, the clamping rod 403 includes a fixed rod 4031, one end of the fixed rod 4031 is fixedly mounted on the inner surface of the bevel gear disk 402, the fixed rod 4031 is hollow, and an extrusion rod 4033 is slidably connected inside the fixed rod 4031, a spring 4032 is provided between the fixed rod 4031 and the extrusion rod 4033, and an arc-shaped clamping plate 4034 is fixedly mounted on one end of the extrusion rod 4033. A spring 4032 is installed inside the clamping rod 403, so that the clamping rod 403 can rebound. When an object is stuffed between the three clamping rods 403, the extrusion rod 4033 on the clamping rod 403 will retract, and then the three extrusion rods 4033 will squeeze each other toward the object under the rebound of the spring 4032, thereby achieving the effect of elastic clamping, which can better fix the object.

[0040] Preferably, two first frames 10 are fixedly mounted on one side of the upper surface of the workbench 2. A rotating belt 15 is provided on the two first frames 10. A printing module 11 is slidably connected to one of the first frames 10 via the rotating belt 15. The printing module 11 sprays ink droplets onto the printed object. A varnish mechanism 12 is slidably connected to the other first frame 10 via the rotating belt 15. The varnish mechanism 12 is used for hot stamping after printing. A second frame 13 is fixedly mounted on both ends of the other side of the upper surface of the workbench 2. A hot stamping module 14 is fixedly mounted on the second frame 13. The hot stamping module 14 is located above the guide rail 7. The transmission chain uses a double-speed chain streamline to transport the printing medium, passing through the printing mechanism, the printing varnish machine, the hot stamping, and then unloading. The carrier is transported to the starting position of the lower transmission chain to the upper transmission chain, and then the carrier is raised to the upper transmission chain for circular transmission.
