Description

Technical Field

[0001] This utility model relates to screen printing, specifically a screen printing device for metal card production. Background Technology

[0002] Existing screen printing equipment, in order to improve the printing effect, is equipped with an inkjet component and a pressing mechanism to evenly press the substrate, so that the ink can be evenly coated on the substrate. However, it cannot print different patterns on multiple workpieces at the same time, and it cannot perform assembly line printing. For example, the screen printing equipment disclosed in Chinese Patent Application No. CN201621421152.X uses an ink jetting mechanism to evenly spray ink onto a carrier plate, and then uses a pressing mechanism to evenly press the substrate, so that the ink can be evenly coated on the substrate, resulting in a better printing effect. However, it cannot print different patterns on multiple workpieces at the same time, and it cannot perform assembly line printing. Utility Model Content

[0003] The purpose of this invention is to provide a screen printing device for the production of metal cards.

[0004] The technical problem solved by this utility model is that, in the prior art, screen printing devices cannot print different patterns on several objects at the same time, nor can they perform assembly line printing. Furthermore, assembly line screen printing devices occupy a large space, and when workers want to observe the printed patterns, they also need to go to each printing component to observe them.

[0005] This utility model can be achieved through the following technical solution: a screen printing device for metal card production, comprising a frame, a limiting frame fixedly connected to the upper surface of the frame, a sliding groove provided inside the limiting frame, a rotating roller rotatably connected inside the frame, a conveyor belt drivingly connected to the side surface of the rotating roller, a support plate fixedly connected to the side surface of the conveyor belt, a limiting block and a telescopic plate one fixedly connected to the upper surface of the support plate; a gear, a rack meshing with the side surface of the gear, a moving plate fixedly connected to the end of the rack, a sliding frame fixedly connected to the side surface of the moving plate, a screen fixedly connected to the inner wall of the sliding frame, a lead screw rotatably connected inside the sliding frame, and a telescopic plate two provided on the side surface of the lead screw. With the above components, a limit block is set on the upper surface of the support plate. Combined with the telescopic plate, it can quickly position the metal card. The conveyor motor rotates the roller, driving the conveyor belt to rotate. This allows the support plate on the conveyor belt surface to descend along the side of the conveyor belt, carrying the metal card. The transmission belt on the side surface of the roller drives the gear to rotate. The toothed part of the gear meshes with a rack, causing the printing component to move away from the conveyor belt as the support plate descends. As the gear continues to rotate, the toothed part then moves the rack below, causing the printing component to move closer to the conveyor belt as the support plate descends, preventing it from interfering with the descent. Different patterns can be printed gradually on the metal card on the descending support plate surface. The device occupies little space, reducing factory rental costs, minimizing ink splatter areas, and allowing workers to easily observe the printing process without moving the metal card.

[0006] A further technical improvement of this utility model is that a conveyor motor is fixedly connected to the front of the frame, and the output end of the conveyor motor is fixedly connected to the end of the rotating roller. These components provide power for the rotation of the rotating roller, enabling it to rotate normally.

[0007] A further technical improvement of this utility model is that: the support plate has several units arranged in an array on the side surface of the conveyor belt, and the limiting block and the telescopic plate are respectively disposed at the front and rear ends of the support plate. These components facilitate simultaneous printing on several objects, or printing different patterns on several objects separately. The limiting block and the telescopic plate work together to facilitate quick positioning and fastening of the objects.

[0008] A further technical improvement of this utility model is that: the inner wall of the gear is fixedly connected to the end of the rotating roller; the gear is rotatably connected to the inside of the frame; the rack has two teeth located at the upper and lower ends of the gear; the gear has teeth only at the quarter-circle arc; and the end of the sliding frame is engaged with the inner wall of the sliding groove. Through these components, the rotating roller can drive the gear to rotate, allowing the gear to slide to the right and left on its upper and lower racks respectively, thus enabling the printing components to move away from and closer to the conveyor belt.

[0009] A further technical improvement of this utility model is that: the side surface of the movable plate is slidably connected to the inner side wall of the limiting frame, and the sliding frame and screen are located directly above the support plate. Through these components, the movable plate can slide normally, and the sliding frame and screen are positioned directly above the support plate, allowing the printing component to print on the object.

[0010] A further technical improvement of this utility model is that a lead screw motor is fixedly connected to the end of the sliding frame, and the output end of the lead screw motor is fixedly connected to the end of the lead screw. These components provide power to the lead screw, enabling it to rotate normally.

[0011] A further technical improvement of this invention lies in that: the second output end of the telescopic plate contacts the surface of the screen, and there are two lead screws located at the front and rear ends of the slide frame. These components enable the second output end of the telescopic plate to evenly scrape ink onto the surface of the screen.

[0012] A further technical improvement of this utility model is that: a groove is formed inside the frame, and the side surface of the rack is slidably connected to the inner wall of the groove. These components enable the rack to slide normally.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Limiting blocks are installed on the upper surface of the support plate. Combined with a telescopic plate, this allows for rapid positioning of the metal cards. A conveyor motor rotates the rollers, driving the conveyor belt to rotate. This allows the support plate on the conveyor belt surface to descend along the side of the conveyor belt, carrying the metal cards. The transmission belt on the side surface of the rollers drives the gears to rotate. The toothed part of the gear meshes with a rack, causing the printing component to move away from the conveyor belt as the support plate descends. As the gear continues to rotate, the toothed part then moves the rack below, bringing the printing component closer to the conveyor belt as the support plate descends, preventing it from interfering with the descent. This allows for the gradual printing of different patterns on the metal cards on the descending support plate surface. The device occupies little space, reducing factory rental costs, minimizing ink splatter areas, and facilitating observation of the printing process by staff, who can monitor the printing status of each metal card without moving the device.

[0023] Please see Figure 1-5 As shown, the screen printing device for producing metal cards in this embodiment includes a frame 1. A limiting frame 2 is fixedly connected to the upper surface of the frame 1. A sliding groove 3 is provided inside the limiting frame 2. A rotating roller 4 is rotatably connected inside the frame 1. A conveyor motor 16 is fixedly connected to the front of the frame 1. The output end of the conveyor motor 16 is fixedly connected to the end of the rotating roller 4. A conveyor belt 5 is drivenly connected to the side surface of the rotating roller 4. A support plate 6 is fixedly connected to the side surface of the conveyor belt 5. Several support plates 6 are arranged in an array on the side surface of the conveyor belt 5. A limiting block 7 and a telescopic plate 8 are fixedly connected to the upper surface of the support plate 6. The limiting block 7 and the telescopic plate 8 are respectively arranged at the front and rear ends of the support plate 6.

[0024] Specifically, the object is placed on the upper surface of the support plate 6, and the telescopic plate 8 is activated to push the object out. With the help of the limiting block 7, the two sides of the object can be fastened to prevent the object from shifting and affecting the printing effect. The conveyor motor 16 is activated to rotate the roller 4, which can drive the conveyor belt 5 to rotate. The conveyor belt 5 drives the support plate 6 on its side surface and the object on its surface to move, which can bring the object under the next printing part and print another pattern on the object. It cannot be operated manually by the staff.

[0025] Gear 9, the inner wall of gear 9 is fixedly connected to the end of roller 4, gear 9 is rotatably connected to the inside of frame 1, and rack 10 is meshed with the side surface of gear 9. There are two racks 10 located at the upper and lower ends of gear 9. Gear 9 has teeth only at the quarter-circle arc. A slot 18 is opened inside frame 1. The side surface of rack 10 is slidably connected to the inner wall of slot 18. A movable plate 11 is fixedly connected to the end of rack 10. The side surface of movable plate 11 is slidably connected to the inner wall of limit frame 2. The side surface of movable plate 11 is fixedly connected to... There is a sliding frame 12, the end of which is fitted into the inner wall of the sliding groove 3. A wire mesh 13 is fixedly connected to the inner wall of the sliding frame 12. The sliding frame 12 and the wire mesh 13 are located directly above the support plate 6. A lead screw 14 is rotatably connected inside the sliding frame 12. There are two lead screws 14 located at the front and rear ends of the sliding frame 12. A lead screw motor 17 is fixedly connected to the end of the sliding frame 12. The output end of the lead screw motor 17 is fixedly connected to the end of the lead screw 14. A telescopic plate 15 is provided on the side surface of the lead screw 14. The output end of the telescopic plate 15 is in contact with the upper surface of the wire mesh 13.

[0026] Specifically, ink is placed on the upper surface of the screen 13, and the telescopic plate 15 is activated so that its output end contacts the upper surface of the screen 13. The lead screw motor 17 is activated to rotate the lead screw 14, which can drive the telescopic plate 15 on its side surface to move, so that the ink can be evenly applied to the upper surface of the screen 13. The ink is then applied to the surface of the object through the screen 13. The rotating roller 4 can drive the gear 9 to rotate, which drives the rack 10 above it to slide inside the slot 18, so that the moving plate 11 slides inside the slide groove 3 in the limiting frame 2. The moving plate 11 can then drive the slide frame 12 to move away from the conveyor belt 5. When the toothed part of the gear 9 drives the rack 10 below it to move, the slide frame 12 can be moved closer to the conveyor belt 5, so that it does not restrict the movement of the support plate 6. After printing one pattern on the object, it moves to the next printing part so that another pattern can be printed on it, without the need for manual operation by the staff.

[0027] In use, the object is placed on the upper surface of the support plate 6, and the telescopic plate 8 is activated to push the object out. The limiting block 7, in conjunction with the limiting block 7, secures the object on both sides to prevent displacement and ensure printing quality. The conveyor motor 16 is activated to rotate the roller 4, which in turn drives the conveyor belt 5 to rotate. The conveyor belt 5 moves the support plate 6 on its side surface and the object on its surface, bringing the object under the next printing component. This allows for printing of a different pattern on the object, eliminating the need for manual operation. Ink is placed on the upper surface of the screen 13, and the telescopic plate 15 is activated so that its output end contacts the upper surface of the screen 13. The lead screw motor 17 is activated to rotate the lead screw 14, which in turn drives the extension plate 14 on its side surface to rotate. The movement of the shrink plate 15 allows ink to be evenly applied to the upper surface of the screen 13, enabling the ink to be applied to the surface of the object through the screen 13. The rotating roller 4 drives the gear 9 to rotate, causing the rack 10 above it to slide inside the slot 18, allowing the moving plate 11 to slide inside the slide groove 3 within the limiting frame 2. The moving plate 11 then drives the slide frame 12 to move away from the conveyor belt 5. When the toothed part of the gear 9 drives the rack 10 below it to move, the slide frame 12 can be moved closer to the conveyor belt 5, allowing it to move without restricting the movement of the support plate 6. This allows the object to be printed with one pattern and then moved to the next printing part so that another pattern can be printed on it, without the need for manual operation by the staff.
