[0049] Reference Figure 5 、 Figure 6 、 Figure 7Two symmetrical rotating cleaning mechanisms 7 are provided on both sides of the supporting square tube 13, and the two rotating cleaning mechanisms 7 have the same structure and installation. The rotating cleaning mechanism 7 includes two fixed blocks 71 fixedly provided on the side of the supporting square tube 13, and the two fixed blocks 71 are symmetrically arranged and are on the same horizontal line. The middle part of the two fixed blocks 71 is movably penetrated by the transmission rod 72, and a driven wheel 73 is fixedly provided at the end of the transmission rod 72 away from the fixed block 71, and a driving wheel 74 is meshed with one side of the driven wheel 73, and the inner ring surface of the driving wheel 74 is clamped and fixed to the end of the rotating high-pressure nozzle 12 away from the supporting square tube 13, and the transmission rod 72 is fixedly penetrated with the middle part of the rotating wheel 75 on the side away from the rotating high-pressure nozzle 12, and the outer ring surface of the rotating wheel 75 and the inner ring surface of the rotating ring 76 are slidably arranged with each other.

[0050] Reference Figure 4 、 Figure 6 、 Figure 7 , and the surface of the rotating ring 76 away from the fixed block 71 is fixedly arranged on the outer ring of the surface of the fixed ring 8 away from the scraper 10, and four telescopic rods 9 are fixed on the outer ring surface of the fixed ring 8, and the four telescopic rods 9 are arranged on the outer ring surface of the fixed ring 8 at a ninety-degree interval, and the four telescopic rods 9 are symmetrical to each other, and the surface of the four telescopic rods 9 away from the fixed ring 8 is fixedly connected to the middle part of the lower surface of the scraper 10, and the surface of the four scrapers 10 away from the telescopic rods 9 is slidingly connected to the inner wall of the outer shell 5, and the inner ring surface of the fixed ring 8 is rotatably connected to the outer ring surface of the high-pressure joint 11 away from the rubber plate 17, and the surface of the high-pressure joint 11 away from the rubber plate 17 is fixedly connected to the surface of the supporting square tube 13 away from the rotating high-pressure nozzle 12.

[0051] The two fixed blocks 71 are located on the same horizontal line to ensure that the transmission rod 72 is always in a parallel state, and the two ends of the transmission rod 72 are fixedly arranged to transmit the driven wheel 73 and the rotating wheel 75. When the driving wheel 74 rotates following the engaged rotating high-pressure nozzle 12, the rotational power is transmitted to the rotating wheel 75 through the transmission rod 72, so that the rotating wheel 75 can rotate synchronously, thereby causing friction between the rotating wheel 75 and the rotating ring 76, thereby driving the rotating ring 76 to rotate. While the rotating ring 76 rotates, the fixed ring 8 fixed to it will rotate around the high-pressure connector 11, thereby causing the telescopic rod 9 and the scraper 10 on the upper part of the fixed ring 8 to rotate together, and the telescopic rod 9 can be extended and retracted according to the inner cavity radius of the cooling roller 1, so that the upper surface of the scraper 10 can always abut against the inner ring surface of the cooling roller 1, thereby achieving better cleaning of the inner ring surface of the cooling roller 1.

[0052] It should be noted that the cleaning and maintenance of the inside of the cooling roller 1 is recommended to be done once a week or once every two weeks to prevent excessive accumulation of water rust inside and making cleaning difficult.

[0053] Among them, the cooling structure of the cooling roller 1 is the existing technology, and a cooling water channel is provided inside the cooling roller 1, so that the cooling roller 1 has the function of cooling and lowering the temperature. Other structures will not be described in detail.

[0054] The implementation principle of a printing roller with a cooling function in the embodiment of the present application is as follows: when cleaning and maintaining the inside of the cooling roller 1, the cooling roller 1 is disconnected from the rotary joints at both ends, and then the hexagonal bolts are rotated in the opposite direction to loosen the limit plates 16, so that the second fixing seat 4 is free from restriction and can be moved, and the second fixing seat 4 is moved to the back of the first fixing seat 3 and the first fixing seat 3 and the second fixing seat 4 are overlapped by cooperating with the T-shaped slide bar 14 and the T-shaped slide groove 15, and then the hexagonal bolts are tightened to limit the limit plates 16 to the second fixing seat 4, and then the high-pressure joint 11 is connected to the high-pressure water pipe equipment. Connect, and then slowly push the entire device into the interior of the cooling roller 1. During the movement, the roller 63 will always move along the inner wall of the cooling roller 1, and the roller 63 will be supported by the cooperation of the scissors support 62 and the fixed slide 61. Under the action of the spring 64, it can better stick to the inner wall of the cooling roller 1, and the entire sliding support mechanism 6 can also support the rotating high-pressure nozzle 12 and the supporting square tube 13 in the middle, so that the rotating high-pressure nozzle 12 always remains in the middle of the inner cavity of the cooling roller 1, and remains stable when flushing the inner cavity of the cooling roller 1.

[0055] When the rotating end of the rotating high-pressure nozzle 12 rotates, it can drive the driving wheel 74 to rotate, and then drive the driven wheel 73 to rotate. The driven wheel 73 drives the rotating wheel 75 to rotate through the transmission rod 72, and then drives the rotating ring 76 and the fixed ring 8 to rotate, so that the telescopic rod 9 and the scraper 10 rotate, and clean the inner cavity side wall of the cooling roller 1, and then use a negative pressure tube or a blow gun to suck out or blow dry the residual liquid in the cooling roller 1. Finally, move the entire device back and forth in the inner cavity of the cooling roller 1 for more than three times to complete. After the end, push the second fixed seat 4 back to its original position for fixation, and fix the cooling roller 1 to the rotary joint.

[0056] The above are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Those skilled in the art will readily appreciate that the present disclosure may be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
