Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to a servo drive mechanism for printing press rollers. Background Technology

[0002] A printing press is a mechanical device that transfers text and images onto a substrate. It consists of mechanisms such as plate mounting, inking, printing, and paper feeding. It achieves batch reproduction by applying ink to the image areas of the printing plate. The printing press is equipped with a plate roller and anilox roller. The honeycomb-shaped concave holes (inking holes) on the surface of the anilox roller store and quantitatively transfer ink to the plate roller. The two work together to ensure uniform ink transfer and achieve the printing operation. However, currently, some printing presses commonly found on the market use different servo motors to drive the rotation of the anilox roller and the plate roller. This not only increases the investment in equipment and production and maintenance costs, but also increases the space occupancy of the equipment. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0022] like Figure 1-5 As shown, this utility model embodiment provides a servo drive mechanism for a printing press roller assembly, including a frame 1. The frame 1 has liftable mounting plates 2 arranged on its symmetrical sides. A printing plate roller 3 and an anilox roller 4 are arranged between the mounting plates 2. Rotating shaft seats are symmetrically arranged on the mounting plates 2. The roller shafts at both ends of the printing plate roller 3 and the anilox roller 4 are respectively mounted on the rotating shaft seats. A first gear 5 and a second gear 6 are respectively arranged on the outer side of one mounting plate 2 at positions corresponding to the roller shafts of the two rollers. The diameters of the first gear 5 and the second gear 6 are different, allowing for different rotational speeds between the two gears to meet printing requirements. The first gear 5 and the second gear 6 are respectively mounted on the roller shafts of the two rollers and mesh with each other. A transmission gear 7 is also arranged on the mounting plate 2 at a position corresponding to the second gear 6. The transmission gear 7 meshes with the second gear 6 and is driven to rotate by a servo motor 8.

[0023] A gearbox 9 is provided on the side of the mounting plate 2 where the gears are installed. The first gear 5, the second gear 6, and the transmission gear 7 are all located inside the gearbox 9. The servo motor 8 is installed on the outside of the gearbox 9. The drive motor 8 passes through the gearbox 9 and is connected to the transmission gear 7.

[0024] The gearbox 9 is fixed to the mounting plate 2 by screws.

[0025] The frame 1 has movable notches 10 on both sides, the mounting plate 2 is installed inside the movable notches 10, and the gearbox 9 is located outside the movable notches 10.

[0026] Mounting wing plates 11 are provided on the frame 1 at positions on both sides within the movable notch 10. A slider 12 is provided on the side of the mounting wing plate 11 facing the mounting plate 2. A slide rail 13 is provided on the mounting plate 2 at the position corresponding to the slider 12. The slider 12 is mounted on the slide rail 13.

[0027] The frame 1 is equipped with a drive cylinder (not shown in the figure) on one or both sides. The piston rod of the drive cylinder is vertically upward and fixedly connected to the lower end of the mounting plate 2. The mounting plate 2 moves up and down within the movable notch 10 under the control of the drive cylinder. When the mounting plate 2 moves, it moves along the slider 12 via the slide rail 13.

[0028] The upper end of the gearbox 9 is provided with an oil tank 14, which contains lubricating fluid. The bottom of the oil tank 14 is provided with a pouring pipe 15, which passes through the top of the gearbox 9 and extends to the top of the first gear 5. An electromagnetic control valve 16 is provided on the pouring pipe 15, and a liquid filling port 17 is provided on the top of the oil tank 14.

[0029] The casting pipe 15 is provided with a diversion connector 18 at one end inside the gearbox 9. The diversion connector 18 is located directly above the first gear 5, and the bottom of the diversion connector 18 is provided with several drip holes.

[0030] A bracket 19 is provided at the bottom of the oil tank 14, and the oil tank 14 is fixedly connected to the top of the gearbox 9 through the bracket 19.

[0031] The oil tank 14 facilitates lubrication of the first gear 5, the second gear 6, and the transmission gear 7. By controlling the solenoid valve 16 to start, the lubricant in the oil tank 14 is delivered to the distributor 18 through the pouring pipe 15, and finally drips onto the first gear 5 through the drip pipe. As the first gear 5 rotates, the lubricant is transferred to the second gear 6 and the transmission gear 7. This eliminates the need for manual lubrication and allows gear maintenance to be completed without disassembling the gearbox 9, greatly improving efficiency.

[0032] The working principle of this utility model is as follows: the rotation of the servo motor 8 drives the transmission gear 7 to rotate in the gearbox 9. At this time, the transmission gear 7 drives the second gear 6 to rotate, and the second gear 6 drives the first gear 5 to rotate. In this way, the printing plate roller 3 and the anilox roller rotate. A single servo motor 8 can control the two roller groups to work together.

[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
