Description

Technical Field

[0001] This utility model relates to the field of printing technology, specifically to a rotary printing mechanism for a nano silver paste screen printing machine. Background Technology

[0002] Printing is a technology that uses processes such as plate making, inking, and pressing to transfer ink to the surface of materials such as paper, textiles, plastics, leather, PVC, and PC to reproduce the content of the original manuscript in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink.

[0003] A search revealed CN215041253U, which discloses a rotary printing mechanism for a nano silver paste screen printing machine. The drive component can drive the printing component to rotate via a transmission chain. When the printing roller in the printing component rotates, it can directly print the pattern or text engraved on its surface onto the paper. In this printing mechanism, the direction of the printing roller's movement at the moment it leaves the paper will form a certain angle with the vertical direction, which will greatly reduce the pulling effect on the fuel. Moreover, the fuel on the surface of the printing roller will not fall off due to gravity and can better adhere to the surface of the printing roller.

[0004] In the process of realizing this utility model, the inventors discovered that at least the following problems in the prior art have not been solved. In the above case, the printing components are rotated by a transmission chain to adjust the printing position and printing speed. However, in use, the transmission chain needs to be manually controlled by the staff, which is cumbersome and has low precision.

[0005] Therefore, we propose a rotary printing mechanism for a nano silver paste screen printing machine, which can solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a rotary printing mechanism for a nano silver paste screen printing machine, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rotary printing mechanism for a nano silver paste screen printing machine, including a printing roller and a mounting base, wherein the mounting base has an internal mounting groove; a driving mechanism for driving the printing roller to rotate, the driving mechanism including a large gear, a small gear and a servo motor, a driven rod horizontally penetrating and fixedly mounted in the middle of the large gear, a driving rod horizontally penetrating and fixedly mounted in the middle of the small gear, the shaft end of the servo motor being fixedly connected to one end of the driving rod, and the large gear meshing with the small gear; a control mechanism for controlling the printing position and printing speed of the printing roller, the control mechanism including a Hall sensor, the Hall sensor being fixedly connected to the inner wall of the top of the mounting groove, a magnet being fixedly mounted on the outer side of the driving rod, and a controller being fixedly connected to the lower part of the mounting base away from the printing roller.

[0008] As an optional solution to the technical solution of this application, a connecting sleeve is fixedly installed at one end of the driven rod located outside the mounting groove, and fixed rods are symmetrically installed at both ends of the printing roller, with the fixed rods being movably connected to the fixed sleeve.

[0009] As an optional solution to the technical solution of this application, the top and bottom ends of the connecting sleeve are symmetrically provided with first fixing holes, the top and bottom ends of the fixing rod are symmetrically provided with second fixing holes, and the printing roller and the driven rod are fixedly connected by bolts passing through the first fixing holes and the second fixing holes.

[0010] As an optional solution to the technical solution of this application, the magnets are evenly distributed on the outside of the drive rod, and the magnets correspond to the Hall sensor.

[0011] As an optional solution to the technical solution of this application, the servo motor is fixedly connected above the side of the mounting base away from the printing roller, and the driven rod is rotatably connected to the lower part of the inner wall on both sides of the mounting groove through bearings.

[0012] As an optional solution to the technical solution of this application, the drive rod is rotatably connected to the upper part of the inner wall on both sides of the mounting groove through bearings, and the large gear and the small gear are matched in size.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: controlling the servo motor to work can drive the drive rod and the small gear to rotate, which in turn drives the driven rod to rotate via the large gear, thereby driving the printing roller to rotate for printing operations. During the rotation of the drive rod, it can drive the magnet to rotate. When the magnet rotates to the upper end of the drive rod and aligns with the Hall sensor, the Hall sensor can transmit data to the controller. Furthermore, the Hall sensor can detect the number of rotations and the rotation speed of the drive rod, thereby further precisely controlling the printing position and printing speed of the printing roller.

[0018] Please see Figures 1-2 This utility model provides a technical solution: a rotary printing mechanism for a nano silver paste screen printing machine, including a printing roller 1 and a mounting base 11, the mounting base 11 having a mounting groove 12 inside; a driving mechanism for driving the printing roller 1 to rotate, the driving mechanism including a large gear 14, a small gear 17 and a servo motor 16, a driven rod 13 horizontally penetrating and fixedly mounted in the middle of the large gear 14, the driven rod 13 being rotatably connected to the lower part of the inner walls on both sides of the mounting groove 12 via bearings, a driving rod 15 horizontally penetrating and fixedly mounted in the middle of the small gear 17, the driving rod 15 being rotatably connected to the upper part of the inner walls on both sides of the mounting groove 12 via bearings, the large gear 14 meshing with the small gear 17, the shaft end of the servo motor 16 being fixedly connected to one end of the driving rod 15, and the servo motor 16 being fixedly connected above the side of the mounting base 11 away from the printing roller 1.

[0019] In this technical solution, the servo motor 16 is controlled by the controller 25 to drive the drive rod 15 to rotate, thereby driving the pinion 17 to rotate stably in the mounting groove 12. Through the meshing of the pinion 17 and the large gear 14, the pinion 17 can drive the large gear 14 to rotate slowly in the mounting groove 12, thereby driving the driven rod 13 to rotate, and further driving the printing roller 1 to rotate for printing.

[0020] In this embodiment, the control mechanism is used to control the printing position and printing speed of the printing roller 1. The control mechanism includes a Hall sensor 19, which is fixedly connected to the inner wall of the top of the mounting groove 12. A magnet 18 is fixedly installed on the outer side of the drive rod 15. The magnets 18 are evenly distributed on the outer side of the drive rod 15 and correspond to the Hall sensor 19. A controller 25 is fixedly connected to the lower side of the mounting base 11 away from the printing roller 1.

[0021] In this technical solution, during the rotation of the drive rod 15, it can drive the magnet 18 to rotate. When the magnet 18 rotates to the point where the upper end of the drive rod 15 is aligned with the Hall sensor 19, the Hall sensor 19 can transmit data to the controller 25. Furthermore, the Hall sensor 19 can detect the number of rotations and rotation speed of the drive rod 15, and further precisely control the printing position and printing speed of the printing roller 1.

[0022] In this embodiment, a connecting sleeve 2 is fixedly installed at one end of the driven rod 13 located outside the mounting groove 12. Fixed rods 22 are symmetrically installed at both ends of the printing roller 1. The fixed rods 22 are movably connected to the fixed sleeve. The top and bottom ends of the connecting sleeve 2 are symmetrically provided with first fixing holes 21, and the top and bottom ends of the fixed rods 22 are symmetrically provided with second fixing holes 23. The printing roller 1 and the driven rod 13 are fixedly connected by bolts 24 passing through the first fixing holes 21 and the second fixing holes 23.

[0023] In this technical solution, the fixing rod 22 at one end of the printing roller 1 is inserted into the connecting sleeve 2 at one end of the driven rod 13 to facilitate the connection between the printing roller 1 and the driven rod 13. The connecting sleeve 2 is fixedly connected to the fixing rod 22 by the bolt 24 passing through the first fixing hole 21 and the second fixing hole 23. Conversely, the bolt 24 can be removed to facilitate the disassembly and replacement of the printing roller 1.

[0024] When using the rotary printing mechanism of a nano silver paste screen printing machine, the fixing rod 22 at one end of the printing roller 1 is inserted into the connecting sleeve 2 at one end of the driven rod 13, facilitating the connection between the printing roller 1 and the driven rod 13. Bolts 24 pass through the first fixing hole 21 and the second fixing hole 23, fixing the connecting sleeve 2 to the fixing rod 22. The controller 25 controls the servo motor 16 to rotate, which in turn drives the drive rod 15 to rotate, thereby causing the pinion 17 to rotate stably within the mounting groove 12. The pinion 17 meshes with the large gear 14, and the pinion... During the rotation of wheel 17, it can drive the large gear 14 to rotate slowly in the mounting groove 12, thereby driving the driven rod 13 to rotate, and further driving the printing roller 1 to rotate for printing. During the rotation of drive rod 15, it can drive magnet 18 to rotate. When magnet 18 rotates to the point where the upper end of drive rod 15 is aligned with Hall sensor 19, Hall sensor 19 can transmit data to controller 25. Furthermore, Hall sensor 19 can detect the number of rotations and rotation speed of drive rod 15, and further precisely control the printing position and printing speed of printing roller 1.
