Description

Technical Field

[0001] This utility model belongs to the field of printing press technology and relates to an adjustment and conversion device for plate-mounting drive. Background Technology

[0002] A printing press is a machine used for printing text and images. It has played a vital role in the dissemination of human civilization and culture. The working principle of a printing press is to make a printing plate containing the text and images to be printed and mount it on the printing press. Then, ink is applied to the areas of the printing plate containing the text and images, either manually or by the printing press itself. The ink is then transferred directly or indirectly to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thus reproducing a printed product identical to the printing plate. This process requires a plate-mounting drive device to operate the printing plate.

[0003] The existing technology has the following technical problems: Most of the existing plate-mounting drive devices are powered by motors. However, if the motor is damaged during long-term operation and the device cannot operate, maintenance personnel need to stop the device for repair. The operation can only continue after the repair is completed. The repair time is long, which seriously reduces the printing efficiency. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the power source of most existing plate-mounting drive devices is driven by motors. However, if the motor is damaged during long-term operation and the device cannot operate, maintenance personnel need to stop the device for repair. Only after the repair is completed can operation continue. The repair time is long, which seriously reduces the efficiency of printing work.

[0005] The present invention discloses an adjustment and conversion device for a plate-mounting drive, comprising a base plate, a plate-mounting device at one end of the top of the base plate, a printing device at the other end of the top of the base plate, a drive shaft at the lower end of one side of the plate-mounting device, a fixed box at the top of the base plate corresponding to the drive shaft, a transmission shaft rotatably connected to the inner side of the fixed box corresponding to the drive shaft, the transmission shaft being fixedly connected to the drive shaft, a transmission gear fixed at the end of the transmission shaft away from the drive shaft, a main motor fixed at the lower inner side of the fixed box, a first drive gear fixed at the output end of the main motor, the first drive gear meshing with the transmission gear, and a conversion component at the inner side of the fixed box corresponding to the transmission shaft.

[0006] The rotating assembly includes a backup motor, which is located inside the fixed box and above the drive shaft. The output end of the backup motor is fixed with a second drive gear, which meshes with the drive gear. A pushing assembly is located inside the fixed box at a position corresponding to the drive gear.

[0007] The pushing assembly includes an electric telescopic rod, which is fixed inside the fixed box and near the drive shaft. A fixed plate is fixed to the telescopic end of the electric telescopic rod. Multiple fixed push rods are fixed to the side of the fixed plate near the drive gear. A rubber ball is fixed to the end of each fixed push rod near the drive gear. An annular groove is formed on the side of the second drive gear corresponding to the rubber ball.

[0008] Multiple limiting sliders are evenly fixed on the inner side of the transmission gear. A limiting groove is opened at the position corresponding to the limiting slider of the transmission gear. The limiting slider is slidably connected to the transmission shaft through the limiting groove. A positioning component is provided on the outer side of the transmission shaft at the middle position of the limiting groove.

[0009] The positioning assembly includes two limiting rings, which are respectively disposed on the outer side of the drive shaft. An internal threaded rod is fixed to the side of the limiting ring away from the drive shaft. A drive screw is threaded to the inner side of the end of the internal threaded rod away from the limiting ring. An adjusting gear is fixed to the end of the drive screw away from the internal threaded rod. Extension plates are fixed to both sides of the fixed plate. A connecting block is fixed to the end of the extension plate away from the fixed plate. An adjusting rack is fixed to the lower end of the connecting block. The adjusting rack meshes with the adjusting gear.

[0010] A limiting block is fixed to the outside of the built-in threaded rod, and the limiting block is slidably connected to the fixed box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: through the cooperative structural design of transmission gears, transmission shafts and rotating components, when the main motor is damaged and cannot be used, the transmission shaft can be rotated by the rotating components, so that the equipment does not need to be stopped for maintenance. The main motor can be maintained when printing is no longer needed, which reduces the time that the printing progress is delayed due to the need to stop the machine for maintenance and improves the practicality of the device.

[0012] By optimizing the component's structural design, when the main motor fails, the electric telescopic rod can be activated. This allows the electric telescopic rod to push the transmission gear closer to the second drive gear via a fixed push rod and rubber ball. When the transmission gear meshes with the second drive gear, the backup motor can be activated to drive both the second drive gear and the transmission gear to rotate simultaneously. This, in turn, drives the transmission shaft and the drive shaft to rotate, allowing the device to continue operating and effectively improving the conversion efficiency of the power output source.

[0020] Example 1

[0021] like Figures 1-6 As shown, the device includes a base plate 1, a plate-mounting device 2 is mounted on one end of the top of the base plate 1, and a printing device 3 is mounted on the other end of the top of the base plate 1. A drive shaft 5 is mounted on the lower side of one side of the plate-mounting device 2. A fixed box 4 is fixed at the top of the base plate 1 and at a position corresponding to the drive shaft 5. To facilitate power transmission to the inside of the plate-mounting device 2, a transmission shaft 9 is rotatably connected to the inner side of the fixed box 4 and at a position corresponding to the drive shaft 5. The transmission shaft 9 is fixedly connected to the drive shaft 5. To facilitate the rotation of the transmission shaft 9 and provide power, a transmission gear 8 is fixed at the end of the transmission shaft 9 away from the drive shaft 5. A main motor 6 is fixed at the lower inner side of the fixed box 4. A first drive gear 7 is fixed at the output end of the main motor 6. The first drive gear 7 is meshed with the transmission gear 8. A conversion component is mounted on the inner side of the fixed box 4 and at a position corresponding to the transmission shaft 9.

[0022] Through the coordinated structural design of the transmission gear 8, transmission shaft 9, and rotating assembly, when the main motor 6 is damaged and cannot be used, the transmission shaft 9 can be rotated by the rotating assembly, so that the equipment does not need to be stopped for maintenance. The main motor 6 can be maintained when printing is no longer needed, reducing the time that is delayed in the printing progress due to the need for downtime maintenance and improving the practicality of the device.

[0023] Example 2

[0024] like Figures 2-6 As shown, in order to provide a backup power source for the rotation of the drive shaft 9, the rotating assembly includes a backup motor 10. The backup motor 10 is located inside the fixed box 4 and above the drive shaft 9. In order to facilitate the rotation of the drive shaft 9 when the backup motor 10 is started, a second drive gear 11 is fixed at the output end of the backup motor 10. The second drive gear 11 is meshed with the drive gear 8. In order to facilitate the meshing of the drive gear 8 and the second drive gear 11 to transmit power, a push assembly is provided inside the fixed box 4 at a position corresponding to the drive gear 8.

[0025] The driving assembly includes an electric telescopic rod 12, which is fixed inside the fixed box 4 and close to the drive shaft 9. A fixed plate 13 is fixed to the telescopic end of the electric telescopic rod 12. In order to facilitate the movement of the transmission gear 8 when the telescopic end of the electric telescopic rod 12 is extended, a number of fixed push rods 21 are fixed on the side of the fixed plate 13 close to the transmission gear 8. A rubber ball 22 is fixed to the end of the fixed push rod 21 close to the transmission gear 8. The structural design of the rubber ball 22 reduces damage to the transmission gear 8. An annular groove 23 is opened on the side of the second drive gear 11 corresponding to the rubber ball 22.

[0026] To facilitate the rotation of the transmission shaft 9 while the transmission gear 8 slides on the outside of the transmission shaft 9, multiple limiting sliders 25 are evenly fixed on the inner side of the transmission gear 8. A limiting groove 24 is opened at the position corresponding to the limiting slider 25 of the transmission gear 8. The limiting slider 25 is slidably connected to the transmission shaft 9 through the limiting groove 24. A positioning component is provided on the outside of the transmission shaft 9 at the middle position of the limiting groove 24.

[0027] When the main motor 6 is damaged, the electric telescopic rod 12 is activated first, causing its telescopic end to extend. As the telescopic end of the electric telescopic rod 12 moves, the fixed plate 13 drives the fixed push rod 21 and the rubber ball 22 to move towards the transmission gear 8. When the fixed plate 13 moves, it can drive the positioning component to release the limit on the transmission gear 8. Then, the rubber ball 22 contacts the transmission gear 8 through the annular groove 23, which can drive the transmission gear 8 to move. When the transmission gear 8 moves to mesh with the second drive gear 11, the electric telescopic rod 12 is controlled to retract. At this time, the positioning component completes the limit on the transmission gear 8, and the backup motor 10 can be activated, causing the backup motor 10 to drive the second drive gear 11 to rotate. When the second drive gear 11 rotates, it drives the transmission shaft 9 to rotate through the transmission gear 8 that meshes with it.

[0028] Example 3

[0029] like Figures 3-6 As shown, to facilitate the movement and limiting of the transmission gear 8, the positioning assembly includes two limiting rings 15, which are respectively set on the outer side of the transmission shaft 9. To facilitate the movement of the limiting rings 15, an internal threaded rod 16 is fixed on the side of the limiting ring 15 away from the transmission shaft 9. The inner side of the internal threaded rod 16 away from the limiting ring 15 is threadedly connected to a drive screw 17. To facilitate the rotation of the drive screw 17, an adjusting gear 18 is fixed on the end of the drive screw 17 away from the internal threaded rod 16. To facilitate the rotation of the adjusting gear 18 when the fixed plate 13 moves, extension plates 14 are fixed on both sides of the fixed plate 13. A connecting block 20 is fixed on the end of the extension plate 14 away from the fixed plate 13. An adjusting rack 19 is fixed on the lower end of the connecting block 20, and the adjusting rack 19 is meshed with the adjusting gear 18. To facilitate the rotation and limiting of the internal threaded rod 16, a limiting block 26 is fixed on the outer side of the internal threaded rod 16, and the limiting block 26 is slidably connected to the fixed box 4.

[0030] When the fixed plate 13 moves, the extension plate 14 drives the connecting block 20 and the adjusting rack 19 fixed to the extension plate 14 to move simultaneously. When the adjusting rack 19 moves, the adjusting gear 18 meshing with it drives the drive screw 17 fixed to the adjusting gear 18 to rotate. When the drive screw 17 rotates, the built-in threaded rod 16 moves along the axial direction of the drive screw 17 under the rotational limiting action of the limiting block 26, thereby driving the limiting ring 15 to move. In turn, the movement of the limiting ring 15 can control the limiting of the transmission gear 8.

[0031] Working principle: When the main motor 6 is damaged, the electric telescopic rod 12 is activated first, causing its telescopic end to extend. As the telescopic end of the electric telescopic rod 12 moves, the fixed plate 13 drives the fixed push rod 21 and the rubber ball 22 to move simultaneously towards the transmission gear 8. When the fixed plate 13 moves, it causes the positioning component to release the restriction on the transmission gear 8. Then, the rubber ball 22 contacts the transmission gear 8 through the annular groove 23, allowing the transmission gear 8 to move. When the transmission gear 8 moves to mesh with the second drive gear 11, the electric telescopic rod 12 is controlled to retract. At this point, the positioning component completes the restriction on the transmission gear 8, and the backup motor 10 can be activated. The standby motor 10 drives the second drive gear 11 to rotate. When the second drive gear 11 rotates, it drives the transmission shaft 9 to rotate through the transmission gear 8 that meshes with it. When the fixed plate 13 moves, it drives the connecting block 20 and the adjusting rack 19 fixed to the extension plate 14 to move simultaneously through the extension plate 14. When the adjusting rack 19 moves, it drives the drive screw 17 fixed to the adjusting gear 18 to rotate through the adjusting gear 18 that meshes with it. When the drive screw 17 rotates, the built-in threaded rod 16 moves along the axial direction of the drive screw 17 under the rotation limit action of the limiting block 26, thereby driving the limiting ring 15 to move. In turn, the movement of the limiting ring 15 can control the limiting of the transmission gear 8.

[0032] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
