Description

Technical Field

[0001] This utility model relates to the technical field of printing equipment, and specifically to a printing roller cleaning mechanism with adjustable spacing. Background Technology

[0002] A printing press is an indispensable machine in the modern printing industry. Primarily used for printing text and images, it presents various types of information on paper in a clear and aesthetically pleasing form through sophisticated processes and complex mechanical operations. The structure of a printing press is typically quite complex, consisting of key mechanisms such as plate mounting, inking, impression, and paper feeding. The plate mounting mechanism is responsible for accurately mounting the printing plate in the designated position, ensuring the accuracy of the printed content; the inking mechanism evenly applies ink to the printing plate, preparing it for printing; the impression mechanism applies appropriate pressure to transfer the image and text from the printing plate to the paper; and the paper feeding mechanism is responsible for orderly transporting the paper to the printing position, ensuring the continuity and stability of the printing process.

[0003] According to Chinese Patent No. CN222407627U, a printing press conveyor roller straightening mechanism is disclosed, including a base plate; a baffle is fixedly connected to the top of the base plate; the baffles are evenly distributed on the top of the base plate; a through groove is formed in the middle of the baffle; a slider is slidably engaged in the middle of each group of through grooves; a sliding groove is formed on the outer wall of the baffle; the sliding groove is evenly distributed on the side wall of the baffle; the sliding groove is set on both sides of the through groove; a stabilizing frame is slidably engaged in the middle of the sliding groove; a first motor is fixedly connected to the side wall of the stabilizing frame; by setting a first electric push rod, the slider can be adjusted to adjust the height of the conveyor roller body; by the first motor, a first connecting rod can be rotated to drive the conveyor roller body to drive the printing roller to convey and print express tape using a second motor; by the third motor, the height of the flattening cover can be adjusted to flatten the raised conveyor roller body, further enhancing the flattening and straightening effect of the printing press conveyor roller straightening mechanism.

[0004] However, during the use of existing printing cylinders, impurities remain on the surface of the printing cylinder after printing. These impurities will then be present in the next printing cycle, resulting in poor printing quality. Utility Model Content

Example

[0024] exist Figure 1-4 This utility model provides a technical solution: an adjustable spacing printing roller cleaning mechanism, including a mounting bracket 1, a mounting plate 2, a printing roller 3, a cleaning bracket 4, a rotating screw 5, and a cleaning brush 16. The mounting plate 2 is fixed to the lower side of the mounting bracket 1, the printing roller 3 rotates between the mounting plates 2, the cleaning bracket 4 is fixed to the rear side of the mounting plate 2, the rotating screw 5 is threadedly connected to the cleaning bracket 4, and the cleaning brush 16 is rotatably connected to the rotating screw 5. The cleaning brush 16 has a limit hole, and a limit rod is fixed on the cleaning bracket 4. The limit hole of the cleaning brush 16 is connected to the limit rod of the cleaning bracket 4. The user can adjust the position of the cleaning brush 16 by rotating the rotating screw 5, thereby facilitating cleaning.

[0025] In one aspect of this embodiment, a control panel 6 is fixed to the side of the mounting bracket 1. The control panel 6 consists of an LED display screen and control buttons. A printing base is fixed to the lower side of the mounting bracket 1. A rotating screw 5 is rotatably connected to a buffer plate 7. A spring rod 8 is fixed on the buffer plate 7. The spring rod 8 is connected to a cleaning brush 16. A limit hole is opened on the cleaning brush 16. The limit hole of the cleaning brush 16 is connected to a limit rod. By rotating the rotating screw 5 inward, the distance between the cleaning brush 16 and the printing roller 3 can be changed. Since the spring rod 8 is located behind the cleaning brush 16, the cleaning brush 16 can reciprocate when cleaning the printing roller 3, thereby improving the cleaning efficiency.

[0026] In one aspect of this embodiment, a limiting slide rail is fixed inside the mounting bracket 1, a drive motor 9 is fixed on the upper side of the mounting bracket 1, and a drive screw 10 is fixed inside the mounting bracket 1. The drive screw 10 is poweredly connected to the drive motor 9. A movable seat 11 is threaded onto the drive screw 10. Movable slots are opened on both sides of the movable seat 11, and the movable slots of the movable seat 11 are connected to the limiting slide rail of the mounting bracket 1. A spring base 12 is fixed on the lower side of the movable seat 11, and a mounting plate 2 is fixed on the buffer spring of the spring base 12. The printing roller 3 is an independent unit, and a limiting bracket 13 is rotatably connected to both sides of the printing roller 3. A sliding plate 14 is fixed between the mounting plates 2, and a sliding groove 15 is opened on the sliding plate 14. The limiting bracket 13 slides in the sliding groove 15. A fixing groove is opened on the sliding plate 14. By connecting the fixed groove of the sliding plate 14 with bolts, the user first adjusts the position of the limiting bracket 13 in the sliding groove 15 according to the printing requirements, and fixes the limiting bracket 13 with bolts, thereby changing the spacing of the printing rollers 3. At the same time, the user can control the operation of the transmission motor 9 to drive the transmission screw 10 to rotate, thereby causing the moving seat 11 to move downward. Since there is a spring base 12 on the lower side, the printing force of the printing rollers 3 on the printed items can be adjusted by adjusting the damping of the spring in the spring base 12. Meanwhile, the user can change the distance between the cleaning brush 16 and the printing rollers 3 by rotating the rotating screw 5 inward. Since the spring rod 8 is located behind the cleaning brush 16, the cleaning brush 16 can generate reciprocating motion when cleaning the printing rollers 3, thereby improving the cleaning efficiency.

[0027] The working principle of this utility model is as follows: In the process of using this utility model, firstly, the user adjusts the position of the limiting bracket 13 in the sliding groove 15 according to the printing requirements, and fixes the limiting bracket 13 with bolts, thereby changing the spacing of the printing rollers 3. At the same time, the user can control the operation of the transmission motor 9 to drive the transmission screw 10 to rotate, thereby causing the moving seat 11 to move downward. Since a spring base 12 is provided on the lower side, the printing force of the printing rollers 3 on the printed items can be adjusted by adjusting the damping of the spring in the spring base 12.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
