Those skilled in the art may make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0025] Please refer to Figures 1 to 3 As shown, a printing roller cleaning device includes a cleaning box 1, a clamping assembly 2, a cleaning assembly 3, a power unit 4 and a water spraying assembly 5. The cleaning box 1 is a box structure with an open top. The clamping assembly 2 is used to clamp the printing roller 7. The clamping assembly 2 is rotatably connected to two opposite side walls inside the cleaning box 1. In this embodiment, the clamping assembly 2 includes a first sleeve 21 and a second sleeve 22 that are respectively rotatably connected to two opposite inner side walls of the cleaning box 1. Both ends of the printing roller 7 are inserted into the first sleeve 21 and the second sleeve 22 respectively. A bolt 23 is provided on the first sleeve 21 and / or the second sleeve 22. One end of the bolt 23 passes through the first sleeve 21 and / or the second sleeve 22 and abuts against the printing roller 7. That is, by abutting the bolt 23 against the printing roller 7, the printing roller 7 is fixedly connected to the clamping assembly 2. When the clamping assembly 2 rotates, the printing roller 7 will be driven to rotate together.

[0026] Preferably, a telescopic cylinder 24 is fixedly provided on the outer side wall of the cleaning box 1 close to the second sleeve 22. The telescopic cylinder 24 can be a telescopic electric cylinder or a telescopic oil cylinder in the prior art, which will not be elaborated here. The output end of the telescopic cylinder 24 passes through the side wall of the cleaning box 1 and is rotatably connected to the second sleeve 22. During implementation, the telescopic cylinder 24 can drive the second sleeve 22 to move towards or away from the first sleeve 21 to adapt to printing rollers 7 of different lengths.

[0027] The cleaning assembly 3 is arranged on one side of the clamping assembly 2 and is used to clean the printing roller 7. The cleaning assembly 3 includes a cleaning roller 31 and bristles 32 evenly distributed on the outer peripheral surface of the cleaning roller 31. The central axis of the cleaning roller 31 is parallel to the central axis of the printing roller 7, and both axial ends of the cleaning roller 31 are rotatably connected to two opposite inner side walls of the cleaning box 1. During implementation, the clamping assembly 2 clamps the printing roller 7, and at this time, the cleaning roller 31 of the cleaning assembly 3 is rotated to wash the surface of the printing roller 7 clean with the bristles 32.

[0028] The water spraying assembly 5 is arranged on one side of the top of the cleaning box 1, and the output end of the water spraying assembly 5 faces the printing roller 7. It is used to spray water on the printing roller 7 during the process of the cleaning assembly 3 cleaning the printing roller 7.

[0029] The power unit 4 includes a first gear 41, a second gear 42 and a third gear 43 that are meshed in sequence. One end of the clamping assembly 2 passes through the side wall of the cleaning box 1 and is fixedly connected to the first gear 41. One end of the cleaning roller 31 passes through the side wall of the cleaning box 1 and is fixedly connected to the second gear 42. A driving motor 44 is fixedly provided on one side of the cleaning box 1, and the output end of the driving motor 44 is fixedly connected to the third gear 43. During implementation, the driving motor 44 drives the third gear 43, the second gear 42 meshed with the third gear 43, and the first gear 41 meshed with the second gear 42 to rotate in sequence. It should be noted that since the first gear 41 and the second gear 42 are in a meshed state, the clamping assembly 2 and the cleaning assembly 3 rotate in opposite directions to better clean the printing roller 7. Further, the number of teeth of the second gear 42 is less than that of the first gear 41, so that the rotation speed of the cleaning assembly 3 is greater than that of the clamping assembly 2.

[0030] Please refer to Figure 3As shown in the figure, in an embodiment of the present utility model, a scraping component 6 for scraping off large pieces of adhered oil stains on the bristles 32 is provided on one side of the interior of the cleaning box 1 close to the cleaning component 3. Among them, the scraping component 6 includes a box body 61 fixed on the inner side wall of the cleaning box 1. Specifically, the box body 61 is fixed on the side wall of the cleaning box 1 close to the cleaning component 3. A plurality of scraping plates 62 are provided on the side of the box body 61 close to the cleaning component 3. The plurality of scraping plates 62 are arranged at intervals along the axial direction of the cleaning component 3. The free end of each scraping plate 62 extends towards the direction close to the cleaning component 3. During implementation, when the cleaning roller 31 rotates, the bristles 32 will contact the scraping plates 62. At this time, the large pieces of adhered oil stains on the bristles 32 will be scraped off by the scraping plates 62, thereby cleaning the bristles 32 and avoiding the cleaning effect of the printing roller 7 being affected due to excessive oil stains on the bristles 32.

[0031] In this embodiment, a plurality of through holes 611 adapted to the scraping plates 62 are provided on one side of the box body 61. A connecting plate 63 is slidably arranged in the box body 61. One ends of the plurality of scraping plates 62 respectively pass through the plurality of through holes 611 and are fixedly connected to the connecting plate 63. At least one pull rod 64 is fixed on the side of the connecting plate 63 away from the scraping plates 62. The free end of the pull rod 64 sequentially passes through the side wall of the box body 61 and the cleaning box 1 and extends to the outside of the cleaning box 1. An elastic member for pushing the connecting plate 63 to move towards the direction close to the cleaning component 3 is provided in the box body 61. Preferably, the elastic member is a spring 65. Two ends of the spring 65 respectively abut against the side of the connecting plate 63 away from the cleaning component 3 and the inner wall of the box body 61.

[0032] During implementation, since the free end of the scraping plate 62 passes through the bristles 32 and extends towards the direction close to the cleaning roller 31, so that during the rotation of the cleaning roller 31, the scraping plate 62 can scrape off the large pieces of adhered oil stains on the bristles 32. By providing the pull rod 64, the connecting plate 63 and the elastic member, when there are too many large pieces of oil stains on the scraping plate 62, the staff can pull the pull rod 64 to drive the connecting plate 63 to move away from the cleaning component 3. At this time, the scraping plate 62 moves into the interior of the box body 61. Also, because the through holes 611 are adapted to the scraping plates 62, thus, the large pieces of oil stains are blocked by the outer side walls of the through holes 611. That is, the large pieces of oil stains cannot enter the box body 61 and are separated from the scraping plates 62. Thereby, the scraping plates 62 can be cleaned. After the cleaning is completed, the staff releases the pull rod 64. At this time, the scraping plate 62 is reset by the elastic force of the spring 65.

[0033] When the present utility model is specifically implemented, the staff places the printing roller 7 between the first sleeve 21 and the second sleeve 22 of the clamping assembly 2, starts the telescopic cylinder 24 to drive the second sleeve 22 to move towards the first sleeve 21 to clamp the printing roller 7, and then rotates the bolt 23 so that the bolt 23 abuts against the outer surface of the printing roller 7. Thereby, the printing roller 7 and the clamping assembly 2 will not rotate relative to each other. Then, the power unit 4 is started to drive the clamping assembly 2 and the cleaning assembly 3 to rotate relative to each other to clean the printing roller 7, and at the same time, the water spraying assembly 5 is started to wash the printing roller 7. When the bristles 32 of the cleaning assembly 3 are adhered with large pieces of oil stains, the scraping assembly 6 can be used to clean the bristles 32. When there are too many large pieces of oil stains on the scraping plate 62, the staff can pull the pull rod 64, and through the cooperation of the scraping plate 62 and the through hole 611, the large pieces of oil stains are separated from the scraping plate 62, thereby achieving the purpose of cleaning the scraping plate 62.

[0034] In the present utility model, the clamping assembly 2, the cleaning assembly 3, the power unit 4 and the water spraying assembly 5 are provided to clean the printing roller 7, which reduces the labor intensity of the staff and has high cleaning efficiency. By setting the telescopic cylinder 24 to drive the second sleeve 22, it is convenient for the clamping assembly 2 to adapt to printing rollers 7 of different lengths. By setting the scraping assembly 6, it is convenient to clean the bristles 32 of the cleaning assembly 3 and avoid the cleaning effect of the printing roller 7 being affected due to too much oil stain adhered to the bristles 32.

[0035] The above description is only a preferred embodiment of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
