Description

Technical Field

[0001] This utility model relates to the technical field of cleaning devices for offset printing rollers, and in particular to an online cleaning device for printing rollers. Background Technology

[0002] Rubber rollers are common and critical components in industrial production such as printing, papermaking, and textiles, and the cleanliness of their surface directly affects production quality and efficiency. Over long-term use, rubber rollers easily accumulate impurities such as ink stains, paper scraps, and fibers, leading to surface wear and functional failure. Therefore, regular cleaning of rubber rollers is an important measure to ensure smooth production and extend their service life.

[0003] Traditional rubber roller cleaning methods usually require manual cleaning by stopping the machine, which is not only time-consuming and labor-intensive, but also affects the normal operation and production efficiency of the production line. To address this, we have proposed an online rubber roller cleaning device. Utility Model Content

[0004] To address the problem that traditional rubber roller cleaning requires manual cleaning with the machine stopped, which is time-consuming and labor-intensive, this invention provides an online rubber roller cleaning device. With the cooperation of a longitudinal adjustment module and a horizontal adjustment module, the device can clean the rubber roller while it is running, achieving online cleaning and improving the cleaning efficiency of the rubber roller.

[0005] This invention provides an online cleaning device for rubber rollers, including a cleaning module, a longitudinal adjustment module for driving the cleaning seat to move longitudinally, and a horizontal adjustment module for driving the cleaning seat to move horizontally. The cleaning module includes a cleaning seat and a cleaning plate disposed on the cleaning seat. The cleaning plate abuts against the outer surface of the rubber roller via the longitudinal adjustment module, and the cleaning plate abutting against the outer surface of the rubber roller moves along the length direction of the rubber roller via the horizontal adjustment module. By setting the longitudinal adjustment module, the contact between the cleaning plate and the rubber roller can be adjusted. By driving the cleaning plate to move horizontally on the rubber roller via the horizontal adjustment module, the rubber roller can be cleaned while it is running.

[0006] Furthermore, the horizontal adjustment module includes a horizontal bar and side supports at both ends of the horizontal bar. The cleaning seat is slidably mounted on the horizontal bar, and the horizontal bar is connected to the vertical adjustment module via the side supports. The cleaning seat, which is slidably mounted on the horizontal bar, drives the cleaning plate to move horizontally.

[0007] Furthermore, the longitudinal adjustment module includes two vertical supports and a linkage assembly. The side supports move longitudinally along the two vertical supports via the linkage assembly. The linkage assembly drives the two side supports to rise and fall.

[0008] Furthermore, the linkage assembly includes a first rack, lifting gears, and a rotating rod. The first rack is mounted on the vertical support, and the lifting gear meshes with it. The lifting gears at both ends of the horizontal bar are mounted on the side supports via the rotating rod. The rotating rod drives the side supports at both ends to move up and down synchronously.

[0009] Furthermore, the linkage assembly also includes a first servo motor and a first transmission gear. The first servo motor is fixedly mounted on a bracket on either side, and the first transmission gear is located at the output end of the first servo motor, meshing with a lifting gear. The first servo motor drives the first transmission gear to rotate, and the rotation of the first transmission gear drives the lifting gear on the corresponding bracket to rotate, thus moving the gear up and down along the first rack.

[0010] Furthermore, the two vertical supports are equipped with first slide rails, and the side support is fixedly equipped with a first slider, which is movably connected to the first slide rails. The cooperation between the first slider and the first slide rails improves the stability of the side support's lifting and lowering.

[0011] Furthermore, the horizontal adjustment module also includes a second rack, a second transmission gear, and a drive component. The second rack is arranged along the length of the horizontal bar, and the second transmission gear meshes with the second rack. The drive component is fixedly mounted on the cleaning seat, and the second transmission gear is connected to the drive component. The drive component drives the second transmission gear to rotate, and the rotation of the second transmission gear allows it to move horizontally along the second rack.

[0012] Furthermore, the driving component includes a second servo motor, a gear transmission box, and a base plate for mounting the driving component. The base plate is fixedly mounted on top of the cleaning seat. The second servo motor is connected to a second transmission gear located below the base plate via the gear transmission box. The output end of the second servo motor is connected to the second transmission gear via the gear transmission box.

[0013] Furthermore, the leveling module also includes a second slide rail, and a second slider is fixedly mounted on the cleaning seat, with the second slider being movably connected to the second slide rail. The cooperation between the second slider and the second slide rail improves the stability of the cleaning seat's horizontal sliding.

[0014] Furthermore, the cleaning seat is equipped with two sets of electric push rods, which are respectively located at both ends of the cleaning seat. The cleaning plate is fixedly mounted on the movable end of the electric push rod. The distance between the cleaning plate and the rubber roller can be finely adjusted using the electric push rods.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention provides an online cleaning device for rubber rollers. By setting a longitudinal adjustment module, the contact between the cleaning plate and the rubber roller can be adjusted. By setting a horizontal adjustment module, the cleaning plate can be moved horizontally along the length of the rubber roller. This allows the rubber roller to be cleaned while it is running, thus achieving online cleaning of the rubber roller and effectively improving the cleaning efficiency of the rubber roller.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0023] To achieve online cleaning of rubber rollers, an online cleaning device for rubber rollers is designed, such as... Figure 1 As shown, the system includes a cleaning module, which includes a cleaning seat 1 and a cleaning plate 2 disposed on the cleaning seat 1. A longitudinal adjustment module is used to drive the cleaning seat 1 to move longitudinally, and a horizontal adjustment module is used to drive the cleaning seat 1 to move horizontally. The cleaning plate 2 abuts against the outer surface of the rubber roller through the longitudinal adjustment module, and the cleaning plate 2 abutting against the outer surface of the rubber roller moves along the length direction of the rubber roller through the horizontal adjustment module.

[0024] The longitudinal adjustment module is activated to move the cleaning seat 1 vertically, so that the cleaning plate 2 comes into contact with the rubber roller. Then, the horizontal adjustment module is activated to move the cleaning seat 1 horizontally along the length of the rubber roller, so that the cleaning plate 2 cleans the rubber roller online. By coordinating the horizontal movement of the cleaning plate 2 with the rotation of the rubber roller, the cleaning plate 2 can clean the rubber roller more evenly, resulting in a good cleaning effect.

[0025] like Figure 2 As shown, specifically, the horizontal adjustment module includes a horizontal bar 3 and side supports 4 disposed at both ends of the horizontal bar 3. The cleaning seat 1 is slidably disposed on the horizontal bar 3, and the horizontal bar 3 is connected to the vertical adjustment module through the side supports 4. The vertical adjustment module drives the side supports 4 at both ends of the horizontal bar 3 to move longitudinally, that is, drives the horizontal bar 3 to move longitudinally.

[0026] The longitudinal adjustment module includes two vertical supports 5 and a linkage assembly. The side support 4 moves longitudinally along the two vertical supports 5 via the linkage assembly. Activating the linkage assembly will cause the side support 4 to rise and fall along the vertical supports 5.

[0027] To ensure synchronous lifting and lowering of the two side supports 4, the linkage assembly includes a first rack 6, lifting gears 7, and a rotating rod 8. The first rack 6 is mounted on the vertical support 5, and the lifting gears 7 mesh with it. The lifting gears 7 at both ends of the horizontal bar 3 are mounted on the side supports 4 via the rotating rod 8. The rotating rod 8 is fixedly connected between the two lifting gears 7 and drives the lifting gears 7 at both ends to rotate synchronously. The vertical movement of the side supports 4 is achieved by the meshing force between the lifting gears 7 and the first rack 6.

[0028] The linkage assembly also includes a first servo motor 9 and a first transmission gear 10. The first servo motor 9 is fixedly mounted on the bracket 4 on either side, and the first transmission gear 10 is located at the output end of the first servo motor 9. The first transmission gear 10 meshes with the lifting gear 7. When the first servo motor 9 is started, it can rotate the first transmission gear 10 to drive the lifting gear 7 to rotate. The rotating rod 8 realizes the transmission between the lifting gears 7 at both ends, and the transmission structure is relatively simple.

[0029] To ensure the stable lifting and lowering of the side supports, the two vertical supports 5 are also equipped with first slide rails 11, and the side support 4 is fixedly equipped with a first slider 12, which is movably connected to the first slide rails 11. The first slider 12 is fixedly connected to the side support 4 by screws, and the first slider 12 slides stably along the first slide rails 11 under the action of gears and racks.

[0030] like Figure 3As shown, specifically, the horizontal adjustment module also includes a second rack 13, a second transmission gear 14, and a drive component. The second rack 13 is arranged along the length direction of the horizontal bar 3, and the second transmission gear 14 is meshed with the second rack 13. The drive component is fixedly mounted on the cleaning seat 1, and the second transmission gear 14 is connected to the drive component. The drive component drives the second transmission gear 14 to rotate, and when the second transmission gear 14 rotates, it generates a meshing thrust with the second rack 13, causing the cleaning seat 1 to move horizontally.

[0031] The driving component includes a second servo motor 15, a gear transmission box 16, and a base plate 17 for mounting the driving component. The base plate 17 is fixedly mounted on the top of the cleaning seat 1. The second servo motor 15 is connected to a second transmission gear 14 located below the base plate 17 via the gear transmission box 16. Starting the second servo motor 15 transmits rotational kinetic energy to the second transmission gear 14 via the gear transmission box 16. When the second transmission gear 14 rotates, the meshing action between the second transmission gear 14 and the second rack 13 provides kinetic energy for the horizontal movement of the cleaning seat 1.

[0032] To ensure stable horizontal movement of the cleaning seat 1, the horizontal adjustment module also includes a second slide rail 18. A second slider 19 is fixedly mounted on the cleaning seat 1, and the second slider 19 is movably connected to the second slide rail 18. The second slider 19 is fixedly connected to the cleaning seat 1 by screws, and the second slider 19 slides stably along the second slide rail 18 under the action of a gear and rack.

[0033] To ensure a tighter fit between the cleaning pad 2 and the rubber roller, two sets of electric push rods 20 are installed on the cleaning seat 1. These two sets of electric push rods 20 are respectively located at both ends of the cleaning seat 1, and the cleaning pad 2 is fixedly mounted on the movable end of each electric push rod 20. Activating the electric push rod 20 allows for fine-tuning of the distance between the cleaning pad 2 and the rubber roller, thus enabling better contact between the cleaning pad 2 and the rubber roller. The cleaning pad 2 can be a cleaning cloth; in this embodiment, the cleaning pad 2 is an arc-shaped scraper fixedly connected to the movable end of the electric push rod 20. Its curvature can be adapted to match the rubber roller, making the arc-shaped scraper and the rubber roller more compatible.

[0034] To further ensure the stability of the horizontal movement of the cleaning seat 1, a chain conveyor belt can be installed. One end of the chain conveyor belt is fixedly mounted on the crossbar 3, and the movable end of the chain conveyor belt is fixedly mounted on the cleaning seat 1. The conveying direction of the chain conveyor belt is consistent with the horizontal movement direction of the cleaning seat 1, thereby providing stable support for the cleaning seat 1. Position sensors 22 are also installed at both ends of the crossbar 3, which not only facilitates the detection of whether the cleaning seat 1 has moved into position horizontally, but also facilitates the control of the cleaning seat 1 to perform reciprocating cleaning work.

[0035] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
