[0024] Example 1: Please refer to Figure 1-6 The utility model provides a technical solution: a separated electro-engraving printing plate roller, including a fixing rod 1, a separation plate roller 2 is arranged on both sides of the fixing rod 1, the two separation plate rollers 2 are in contact, a positioning ring 3 is arranged on both sides of the separation plate roller 2, the positioning ring 3 is movably sleeved on the fixing rod 1, a plurality of first positioning rods 6 are installed on the positioning ring 3, a plurality of first positioning grooves 7 are provided on the separation plate roller 2, the first positioning rod 6 is inserted into the first positioning groove 7, a positioning structure is provided on the fixing rod 1 and the positioning ring 3, a fixing structure is provided on the positioning structure and the positioning ring 3, a plurality of second positioning grooves 9 are provided on the separation plate roller 2, a plurality of second positioning rods 8 are installed on the fixing rod 1, and the second positioning rods 8 is inserted into the second positioning groove 9. When using the device, the second positioning grooves 9 on the two separation rollers 2 are aligned with the second positioning rod 8 on the fixing rod 1 and inserted, thereby the fixing rod 1 and the separation roller 2 can be combined together for use, and then the positioning ring 3 is sleeved on the fixing rod 1, and the first positioning rod 6 on it is aligned with the first positioning groove 7 on the two separation rollers 2 and inserted, thereby the two separation rollers 2 can be tightly combined together to prevent them from falling off during use and improve stability. The fixing rod 1, the separation roller 2 and the positioning ring 3 adopt a separate structure. When they are damaged, there is no need to replace them as a whole, which saves costs and is more environmentally friendly.

[0025] The positioning structure includes a rotating ring 4, a rotating groove 41 is provided on one side of the positioning ring 3, the rotating ring 4 is rotatably installed in the rotating groove 41, a plurality of connecting rods 42 are rotatably installed on the rotating ring 4, a plug-in block 43 is rotatably installed on the connecting rod 42, the plug-in block 43 is slidably installed on the positioning ring 3, a plug-in groove 44 is provided on the fixing rod 1, the plug-in block 43 is plugged into the plug-in groove 44, after the positioning ring 3 is sleeved on the fixing rod 1 and the first positioning rod 6 is plugged into the first positioning groove 7, the rotating ring 4 is rotated, and the rotation of the rotating ring 4 drives one end of the connecting rod 42 to rotate, and the other end drives the plug-in block 43 to slide downward and be plugged into the plug-in groove 44 on the fixing rod 1, thereby fixing the positioning ring 3 to prevent it from falling off during use and affecting the normal use of the separation roller 2, thereby improving the stability during use.

[0026] Furthermore, a T-shaped groove 48 is provided on the inner wall of the bottom of the rotating groove 41, and a T-shaped slider 47 is installed at the bottom of the rotating ring 4. The T-shaped slider 47 is rotatably installed in the T-shaped groove 48. The T-shaped slider 47 and the T-shaped groove 48 have a certain limiting effect on the rotating ring 4, so that the rotating ring 4 always rotates in the original position, thereby driving the connecting rod 42 to rotate, and driving the plug-in block 43 to be plugged into the fixing rod 1 for fixation.

[0027] Furthermore, a sliding groove 45 is provided on the positioning ring 3, and the plug-in block 43 is slidably installed in the sliding groove 45.

Then, the positioning ring 3 is sleeved on the retaining rod 1, and the first positioning rod 6 on it is aligned with the first positioning groove 7 on the two separating rollers 2 and inserted. Then, the two separating rollers 2 can be tightly combined together. Then, the rotating ring 4 is rotated, and the rotating ring 4 drives one end of the connecting rod 42 to rotate. Under the limiting action of the sliding groove 45 and the limiting groove 46, the other end of the connecting rod 42 drives the plug-in block 43 to slide downward and be plugged into the plug-in groove 44 on the retaining rod 1. Thus, the positioning ring 3 can be fixed to prevent it from falling off during use and affecting the normal use of the separating roller 2, thereby improving the stability during use. The retaining rod 1, the separating roller 2 and the positioning ring 3 adopt a separate structure. When they are damaged, there is no need to replace them as a whole, which saves costs and is more green and environmentally friendly. At the same time, the operation is very convenient and quick, and will not delay production time.

[0029] Embodiment 2: The retaining structure includes an L-shaped frame 5, which is installed on the rotating ring 4. A threaded rod 51 is threadedly installed on the L-shaped frame 5, and the bottom of the threaded rod 51 is inserted into the positioning ring 3. After the plug-in block 43 is inserted into the retaining rod 1 to fix the positioning ring 3, the threaded rod 51 is rotated so that the threaded rod 51 is inserted into the positioning ring 3, thereby fixing the rotating ring 4 to prevent the rotating ring 4 from loosening during use, causing the plug-in block 43 to slide out of the retaining rod 1 and lose the limiting effect on the positioning ring 3.
