Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a printing roller cleaning device. Background Technology

[0002] In the printing process, the printing roller is a key component for printing patterns on fabric. However, with continuous use of the printing roller or the need to change different colors of dye, cleaning is a necessary step to maintain printing quality and avoid color contamination. However, on some large printing devices, the printing rollers are often large in size and fixed in their installation position, making it difficult to disassemble and replace them in a conventional manner, which brings great inconvenience to the cleaning work. Therefore, on-site operators usually need to manually clean the printing rollers directly in the installed state. In order to ensure the cleaning effect and thoroughly remove residual dye or paste from the roller surface, the printing roller needs to be kept rotating slowly during the operation. Although this method of wiping while rotating improves the cleaning efficiency to a certain extent, it also harbors serious safety risks. When the rag or hand used by the operator comes into contact with the rotating printing roller, it is very easy to be caught or pinched by it. This can cause damage to the equipment or even personal injury to the operator, constituting a safety hazard that cannot be ignored in the production process. Utility Model Content

[0018] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0019] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0020] according to Figures 1-5 As shown, a printing roller cleaning device includes a frame 1 on which a printing roller 2 is mounted. The printing roller 2 includes an upper roller and a lower roller for printing on fabric. A mounting arm 3 is located below the printing roller 2. A cleaning device is mounted on the frame 1 via the mounting arm 3. The cleaning device includes a drive device 4, on which a pair of brushes 5 are mounted. The drive device 4 controls the brushes 5 to move laterally back and forth to clean the printing roller 2. Lifting arms 6 are located on both sides of the drive device 4, providing height adjustment so that the brushes 5 can clean the upper and lower rollers respectively. For cleaning, the bottom of the lifting arm 6 is connected to the mounting cantilever 3. Both the mounting cantilever 3 and the bottom of the lifting arm are provided with through holes 8. A through shaft 7 is provided at the position of the through hole 8. The lifting arm 6 is rotatably mounted on the mounting cantilever 3 through the cooperation of the through hole 8 and the through shaft 7. The cleaning device can be flipped on the frame 1 through the cooperation of the through hole 8 and the through shaft 7. When cleaning is required, the cleaning device can be manually flipped to the position of the printing roller 2 to clean the printing roller 2, or flipped to the bottom position of the frame 1 for storage. When needed, the through shaft 7 can also be removed to disassemble the cleaning device, and it can be reinstalled when cleaning is required.

[0021] The driving device 4 includes a housing 41, in which an adjusting screw and a guide rod 42 are disposed. One end of the adjusting screw is connected to a drive motor 43. The adjusting screw includes a pair of threaded rods 44, which are fixedly connected by a connecting block 45. The threads on the two threaded rods 44 are arranged in opposite directions. Each threaded rod 44 has a movable block 46, which is simultaneously disposed on the adjusting screw and the guide rod 42. The brush plate 5 is disposed on the movable block 46. By controlling the rotation of the adjusting screw through the drive motor 43, the movable block 46 can be controlled to move along the adjusting screw and the guide rod 42. The opposite direction of the threads on the two threaded rods 44 allows the brush plate 5 to move synchronously away from and towards each other, thereby achieving the cleaning action of the printing roller 2.

[0022] The lifting arm 6 includes an inner arm 61 and an outer arm 62. A guide rail 63 is provided on the outer arm 62. The inner arm 61 is movably mounted in the outer arm 62 via the guide rail 63. An elongated groove 64 is provided on the outer arm 62, and a fixing bolt 65 is provided in the elongated groove 64. A fixing screw hole 66 that mates with the fixing bolt 65 is provided at a fixed position on the inner arm 61. By loosening the fixing bolt 65, the inner arm 61 can move up and down in the outer arm 62 along the guide rail 63. When the fixing bolt 65 moves to the highest position of the elongated groove 64, the brush plate 5 is adjusted to the cleaning position corresponding to the upper roller; and when the fixing bolt 65 moves to the lowest position of the elongated groove 64, the brush plate 5 is adjusted to the cleaning position corresponding to the lower roller, allowing the operator to accurately and quickly adjust the position of the brush plate 5.

[0023] The outer arm 62 is provided with a hanging plate 67 at the bottom position. The hanging plate 67 is provided with a hanging hole 68. The frame 1 is provided with a hook 69 that cooperates with the hanging hole 68. When the cleaning device is cleaning, it is hung on the hanging hole 68 by the hook 69, so that the lifting arm 6 remains stable in the working state and prevents it from rotating accidentally and causing the brush plate 5 to deviate from its position.

[0024] The mounting cantilever 3 is provided with a pin hole 31. When the cleaning device is in the storage state, a pin is inserted into the elongated groove 64 and the pin hole 31 to fix the cleaning device.

[0025] The through shaft 7 has threaded sections at both ends, and a limit nut 9 is provided on the threaded section. The limit nut 9 can prevent the through shaft 7 from falling off due to accidental circumstances. The through shaft 7 and the through hole 8 are located at the non-threaded section.

[0026] In practical use, the entire cleaning device, through the cooperation of the through hole 8 and the through shaft 7, can rotate relative to the frame 1 like a hinge, with the through shaft 7 as the axis. When cleaning the printing roller 2 is required, the operator can manually rotate the cleaning device to the position directly opposite the printing roller 2 to make it ready. Conversely, when the cleaning work is completed or it is not needed for the time being, it can also be manually rotated back to the bottom position of the frame 1 for storage, thereby avoiding occupying operating space. If it is necessary to completely remove the cleaning device from the printing machine frame, for example, for maintenance, replacement or long-term storage, the operator can first remove the limit nuts 9 at both ends of the through shaft 7, and then pull the through shaft 7 out of the through hole 8. The entire cleaning device can then be completely separated from the frame 1. When it is needed for use again, simply align the cleaning device with the mounting cantilever, reinsert the through shaft 7, and tighten the limit nuts 9 to complete the installation.

[0027] During the cleaning process, the printing roller 2 rotates slowly, and the brush plate 5, driven by the drive device 4, continuously scrapes and brushes the surface of the printing roller, thereby removing dyes, pastes or other stains adhering to the roller surface, ensuring the thoroughness and efficiency of cleaning; the position of the brush plate 5 can be adjusted by the lifting arm 6, so that the upper roller and the lower roller can be cleaned separately.

[0028] This ingenious design uses a drive mechanism to control the brush plate to move back and forth laterally, enabling comprehensive and even cleaning of the printing roller surface. This ensures the cleanliness of the printing roller, thereby guaranteeing the quality of subsequent printing. It also eliminates the need for operators to manually touch and wipe the rotating printing roller, protecting their safety and reducing workload. The cleaning device's flip-up and detachable installation allows it to be easily deployed to the cleaning location or stored at the bottom of the frame as needed, saving space and facilitating management.

[0029] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
