Detailed implementation manners

[0025] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] Please refer to Figures 1 to 4As shown in the figure, a printing roller cleaning device includes a box body 1, a clamping assembly 2, a power unit 3, a brush plate assembly 4, a pushing assembly 5, and an elastic limiting assembly 6. The box body 1 is a rectangular box with an open top. The clamping assembly 2 is rotatably connected to the box body 1 and is used for clamping the printing roller 10. The power unit 3 is fixedly arranged on one side of the box body 1 and is used for driving the clamping assembly 2 to rotate, thereby driving the printing roller 10 to rotate within the box body 1. The brush plate assembly 4 is arranged within the box body 1 and is located on one side of the clamping assembly 2. When the power unit 3 drives the printing roller 10 to rotate, the brush plate assembly 4 is used for scrubbing the outer surface of the printing roller 10. In this embodiment, two horizontally arranged sliding grooves 11 are formed in the upper part of the side wall of the box body 1, and the two sliding grooves 11 are respectively located on both sides of the box body 1 in the length direction. One side of the brush plate assembly 4 is slidably connected within the two sliding grooves 11. The pushing assembly 5 is arranged on the clamping assembly 2 and is used for pushing the brush plate assembly 4 to slide along the sliding grooves 11. The elastic limiting assembly 6 is arranged on the outer side wall of the box body 1 and is used for preventing the brush plate assembly 4 from sliding.

[0027] During implementation, the staff clamps the printing roller 10 to be cleaned within the clamping assembly 2, and then starts the power unit 3 to drive the clamping assembly 2 to rotate, thereby driving the printing roller 10 to rotate. At this time, the brush plate assembly 4 cleans the surface of the printing roller 10. During the rotation of the clamping assembly 2, the pushing assembly 5 will push the brush plate assembly 4 to slide along the sliding grooves 11, while the elastic limiting assembly 6 will prevent the brush plate assembly 4 from sliding, that is, the elastic limiting assembly 6 enables the brush plate assembly 4 to perform elastic reset. Thus, the brush plate assembly 4 can swing left and right to improve the cleaning ability, and further better clean the outer surface of the printing roller 10.

[0028] It should be noted that in the above implementation manner, a cleaning liquid (such as water) needs to be injected into the box body 1, and the lower part of the printing roller 10 needs to be accommodated in the cleaning liquid. Please refer to Figure 1 and Figure 2 As shown in the figure, preferably, a filter 7 is connected to the bottom of the box body 1 in a communicating manner, and a spraying mechanism 8 is fixedly arranged on the top of the box body 1. The filter 7 is connected to the spraying mechanism 8 through a pump body 9. The spraying mechanism 8 is an existing technology. Specifically, the spraying mechanism 8 includes a pipe body 82 and a spraying head 81. The cleaning liquid is pressurized by the pump body 9, and then the cleaning liquid is sprayed onto the outer surface of the printing roller 10 by the spraying head 81, which will not be elaborated here. By setting the filter 7 and the pump body 9, the cleaning liquid can be recycled to avoid waste of water resources. By setting the spraying mechanism 8, the lower part of the printing roller 10 does not need to be accommodated in the cleaning liquid, that is, only a small amount of cleaning liquid needs to be set in the box body 1 for recycling. Preferably, the filter 7 is a hand-operated filter to facilitate cleaning of foreign matters scrubbed from the outer surface of the printing roller 10.

[0029] In this embodiment, the clamping assembly 2 includes two first sleeves 21 arranged in a mirror image. The two first sleeves 21 are respectively located on both sides of the box body 1 in the length direction. On the side of each first sleeve 21 away from the other, a rotating rod 22 is fixedly provided. The free end of each rotating rod 22 passes through the corresponding side wall of the box body 1 and is rotatably connected to the box body 1, and at the same time is slidably connected to the side wall of the box body 1. In this embodiment, a fixing ring 221 is fixedly provided at the end of the rotating rod 22 outside the box body 1, that is, the rotating rod 22 can slide in the direction away from the box body 1, and by providing the fixing ring 221, the rotating rod 22 is prevented from moving in the direction close to the inside of the box body 1. A second spring 23 is sleeved on the outside of each rotating rod 22, and both ends of the second spring 23 are respectively abutted against the inner side wall of the box body 1 and the first sleeve 21.

[0030] Please refer to Figure 1 and Figure 3 As shown, during implementation, the staff first inserts one end of the printing roller 10 into one of the first sleeves 21, and then needs to push the other first sleeve 21 to move the two first sleeves 21 in the direction away from each other. At this time, the second springs 23 on the two first sleeves 23 are compressed until the distance between the two first sleeves 21 is greater than the length of the printing roller 10. Then the staff inserts the other end of the printing roller 10 into the other first sleeve 21, and then the two second springs 23 are elastically reset. At this time, due to the elasticity of the two second springs 23, the printing roller 10 is firmly clamped in the two first sleeves 21.

[0031] It should be noted that after the two first sleeves 21 clamp the printing roller 10, the printing roller 10 and the two first sleeves 21 are fixedly connected, that is, they do not rotate relative to each other. Thus, when the clamping assembly 2 rotates, the printing roller 10 can be driven to rotate. Specifically, the inner wall of the first sleeve 21 and the two ends of the printing roller 10 can be in interference fit, or the printing roller 10 can be limited by bolts passing through the side wall of the first sleeve 21, and no limitation is set here.

[0032] In this embodiment, the brush plate assembly 4 includes a support plate 41 and a plurality of bristles 42 fixedly provided on one side of the support plate 41. The free ends of the plurality of bristles 42 extend in the direction close to the printing roller 10 and are abutted against the printing roller 10 for washing the outer surface of the printing roller 10. Two connecting rods 43 are fixedly provided at intervals on the side of the support plate 41 away from the bristles 42. The free ends of the two connecting rods 43 respectively pass through the corresponding sliding grooves 11 and are slidably connected to the sliding grooves 11.

[0033] Please refer to Figure 1 、 Figure 2As shown, there are two elastic limiting components 6, and the two elastic limiting components 6 respectively correspond to the two sliding grooves 11. The elastic limiting component 6 includes a fixed frame 61 fixedly arranged on the outer side wall of the box body 1, and a connecting seat 62 slidably arranged inside the fixed frame 61. The connecting seat 62 is used for clamping the connecting rod 43. On both sides in the length direction inside the fixed frame 61, there are respectively arranged first springs 63. One ends of the two first springs 63 respectively abut against the two side walls of the connecting seat 62, and the other ends of the two first springs 63 respectively abut against the side walls of the corresponding fixed frame 61. By arranging the connecting seat 62 and the two first springs 63, elastic limiting can be carried out on the connecting rod 43.

[0034] Please refer to Figure 4 As shown, the pushing component 5 includes an annular plate 51 fixedly sleeved on any one of the first sleeves 21. One end of the support plate 41 extends towards the direction close to the annular plate 51 and is fixedly provided with a ball 411. On the side of the annular plate 51 close to the support plate 41, a plurality of bumps 52 are fixedly arranged. The plurality of bumps 52 are evenly arranged along the circumferential direction of the annular plate 51.

[0035] During implementation, the power unit 3 drives the first sleeve 21 of the clamping component 2 to rotate, and then drives the annular plate 51 to rotate. When the bump 52 on the annular plate 51 abuts against the ball 411 on the support plate 41, the support plate 41 slides along the sliding groove 11 in the direction away from the annular plate 51. As the annular plate 51 rotates, when the ball 411 on the support plate 41 is located between the two bumps 52, the support plate 41 is reset by the elasticity of the two first springs 63 of the elastic limiting component 6. Since the plurality of bumps 52 are evenly arranged along the circumferential direction of the annular plate 51, therefore, as the annular plate 51 rotates, the support plate 41 will repeatedly repeat the above-mentioned sliding and resetting processes, thereby enabling multi-directional washing of the printing roller 10 in the axial and circumferential directions, and further better cleaning the outer surface of the printing roller 10.

[0036] Preferably, one clamping component 2, one brush plate component 4 and one pushing component 5 are defined as a set of washing mechanisms (not indicated in the figure). There are two sets of washing mechanisms arranged inside the box body 1, respectively located on both sides in the width direction of the box body 1.

[0037] Please refer to Figure 2 As shown, in this embodiment, the power unit 3 includes a first motor 31 and a first sprocket 32 fixedly sleeved on the output end of the first motor 31. On the rotating rod 22 close to one side of the first motor 31, second sprockets 33 are fixedly sleeved. A chain 34 is sleeved outside the first sprocket 32 and each second sprocket 33. During implementation, the first motor 31 is started, the first motor 31 drives the first sprocket 32 to rotate, the first sprocket 32 drives the chain 34 to rotate, and then drives the second sprocket 33 fixedly sleeved on the rotating rod 22 to rotate.

[0038] When the specific implementation of the utility model is carried out, first, the staff clamp the printing roller 10 in the clamping assembly 2, and then start the first motor 31. The first motor 31 drives the first sprocket 32, the chain 34 and the second sprocket 33 to rotate in sequence, thereby driving the clamping assembly 2 and the printing roller 10 to rotate. At this time, multiple bristles 42 on the brush plate assembly 4 clean the outer surface of the printing roller 10. While starting the first motor 31, start the pump body 9. The pump body 9 pumps the cleaning liquid in the box body 1 into the spraying mechanism 8, and the spraying head 81 of the spraying mechanism 8 sprays it onto the printing roller 10 to facilitate the washing of the printing roller 10 by the brush plate assembly 4. During the process of the first motor 31 driving the clamping assembly 2 to rotate, through the mutual pushing of the convex block 52 on the annular plate 51 of the pushing assembly 5 and the ball 411 on the support plate 41, and cooperating with the elastic limiting assembly 6, the brush plate assembly 4 will shake along the chute 11, thereby enabling multi-directional washing of the printing roller 10 in the axial and circumferential directions, and further better cleaning the outer surface of the printing roller 10.

[0039] The above description is only the preferred embodiment of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
