[0027] The present invention provides the following technical solutions:

[0028] Embodiment 1

[0029] Please refer to Figures 1-3 , the present invention provides a technical solution: a dust removal device for the surface of a plate roller, including a workbench 1, a clamping and rotating mechanism 2 is arranged on the front of the top of the workbench 1, and a dust removal mechanism 3 is fixedly connected to the top of the workbench 1;

[0030] The clamping and rotating mechanism 2 mainly includes a clamping component 21 and a rotating component 22. The clamping component 21 is arranged on the front of the top of the workbench 1, and the rotating component 22 is arranged inside the clamping component 21;

[0031] The clamping assembly 21 includes a first connecting frame 211. The first connecting frame 211 is fixedly connected to the front of the top of the workbench 1. At the top left of the first connecting frame 211, an L-shaped plate 212 is fixedly connected. On the left side of the L-shaped plate 212, a screw rod 213 is provided. The left end of the screw rod 213 is fixedly connected to a crank 214. A screw plate 215 is threadedly connected to the surface of the screw rod 213. A limiting rod 216 is fixedly connected to the left side of the first connecting frame 211.

[0032] On the left side of the L-shaped plate 212, a hole matching the screw rod 213 is opened, and the surface of the screw rod 213 penetrates and is rotatably connected to the hole. The right end of the screw rod 213 is rotatably connected to the top left of the first connecting frame 211.

[0033] On the right side of the screw plate 215, a hole matching the limiting rod 216 is opened, and the screw plate 215 is slidably connected to the surface of the limiting rod 216 through the hole. The limiting rod 216 limits the screw plate 215, so that the screw plate 215 can only move left and right as the screw rod 213 rotates.

[0034] The rotating assembly 22 includes a first rotating shaft 221. The first rotating shaft 221 is arranged on the right side of the first connecting frame 211. A first gear 222 is fixedly connected to the surface of the first rotating shaft 221. On the front right of the top of the workbench 1, a fixed sleeve frame 224 is fixedly connected. A motor 225 is fixedly connected inside the fixed sleeve frame 224. A second gear 226 is fixedly connected to the surface of the output shaft of the motor 225. A first chuck 223 is fixedly connected to the left end of the first rotating shaft 221. A rectangular groove 227 is opened on the left side inside the first connecting frame 211. A second rotating shaft 228 is rotatably connected to the right side of the screw plate 215. A second chuck 229 is fixedly connected to the right end of the second rotating shaft 228.

[0035] On the left side of the first connecting frame 211, a hole matching the first rotating shaft 221 is opened, and the surface of the first rotating shaft 221 penetrates and is rotatably connected to the hole. The first gear 222 meshes with the second gear 226.

[0036] Embodiment Two

[0037] Please refer to Figures 4-5 , and on the basis of Embodiment One, a dust removal mechanism 3 is further obtained.

[0038] The dust removal mechanism 3 includes a second connecting frame 31. The second connecting frame 31 is fixedly connected to the top of the workbench 1. A cylinder 32 is fixedly connected to the left side inside the second connecting frame 31. The output end of the cylinder 32 is fixedly connected to a sliding frame 34. A sliding groove 33 is opened at the bottom of the second connecting frame 31. Guide rods 35 are symmetrically arranged at the front of the sliding frame 34 in the front and back directions. The rear ends of the guide rods 35 are fixedly connected to limiting plates 36. The front ends of the guide rods 35 are fixedly connected to connecting blocks 37. A brush block 38 is fixedly connected to the front of the connecting blocks 37. A spring 39 is sleeved on the surface of the guide rods 35 between the connecting blocks 37 and the sliding frame 34.

[0039] The surface of the sliding carriage 34 is slidably connected within the sliding groove 33. A hole matching the guide rod 35 is formed on the front surface of the sliding carriage 34, and the surface of the guide rod 35 penetrates and is slidably connected within the hole. One end of the spring 39 is fixedly connected to the front surface of the sliding carriage 34, and the other end of the spring 39 is fixedly connected to the back surface of the connecting block 37.

[0040] During the actual operation process, when this device is in use, first rotate the crank 214 to make the screw plate 215 rotate. The screw plate 215 is limited by the limiting rod 216, so the rotation of the screw rod 213 will cause the screw plate 215 to move leftward. Then place the plate cylinder between the first chuck 223 and the second chuck 229, and reverse-rotate the screw rod 213 to make the screw plate 215 move rightward, so that the second chuck 229 moves rightward to fix the plate cylinder between the first chuck 223 and the second chuck 229. This process can clamp and fix plate cylinders of different lengths. After fixing, start the motor 225 to make the second gear 226 rotate. Since the second gear 226 meshes with the second gear 226, the rotation of the second gear 226 will cause the first gear 222 to rotate, so that the first rotating shaft 221 rotates. The first rotating shaft 221 drives the plate cylinder clamped by the first chuck 223 and the second chuck to rotate, so that the brush block 38 can clean the carbon ink on the surface of the plate cylinder more thoroughly.

[0041] After clamping the plate cylinder, start the motor 225 to make the plate cylinder rotate, and then start the air cylinder 32 to make the brush block 38 move back and forth left and right. At this time, the brush block 38 will tightly fit the surface of the plate cylinder by the elastic force of the spring 39 to better clean the carbon ink on the surface of the plate cylinder.

[0042] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
