DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figure 1-Figure 7 A cleaning device for an ink printing roller comprises a cleaning box 1 and a control box 2 installed on one side of the cleaning box 1. A cleaning chamber 101 is opened on the upper surface of the cleaning box 1. A transmission mechanism and a moving mechanism are connected to the outer wall of the cleaning box 1. The output ends of the transmission mechanism and the moving mechanism both pass through the outer wall of the cleaning box 1 and are connected to a rotating assembly. The printing roller is located between the two rotating assemblies. A lifting mechanism is connected to the bottom surface of the cleaning chamber 101. A supporting assembly is connected to the end of the lifting mechanism away from the bottom surface of the cleaning chamber 101. The outer wall of the printing roller abuts against the supporting assembly.

[0028] The ink printing roller cleaning device in the utility model is similar in structure to the existing ink printing roller cleaning device, such as the ultrasonic cleaning device of model LR-C20. Figures 1 to 7 As shown, when the ink printing roller needs to be cleaned, the cleaning device for the ink printing roller of the utility model can follow the following steps:

[0029] 1. First, add an appropriate amount of cleaning liquid into the cleaning chamber 101, and turn on the ultrasonic cleaning switch of the cleaning box 1 itself through the control button of the control box 2;

[0030] 2. Then place the ink printing roller to be cleaned on the support assembly, and then push the ink printing roller along the surface of the support assembly so that the shaft rod at one end of the ink printing roller is aligned with the rotating assembly close to the control box 2;

[0031] 3. Then, the controller on the control box 2 controls the lifting mechanism to descend, so that the support assembly and the ink printing roller can be brought down together, and during the descent of the ink printing roller, the previously aligned ink printing roller shaft will fall exactly on the rotating assembly close to the control box 2;

[0032] 4. Then stop the lifting mechanism and start the moving mechanism. After the moving mechanism is started, it drives the rotating assembly and the ink printing roller on the side close to the control box 2 to move toward the side away from the control box 2;

[0033] 5. When the end of the ink printing roller away from the control box 2 is aligned with the other rotating assembly, the moving mechanism is stopped;

[0034] 6. Then, the lifting mechanism is turned on again. At this time, because both ends of the ink printing roller are located in the two rotating components, when the lifting component drives the supporting component to descend, the ink printing roller can be located exactly on the two rotating components;

[0035] 7. Finally, the transmission mechanism is turned on, and the transmission mechanism drives the two rotating components to rotate, which can then drive the entire ink printing roller to rotate in the cleaning chamber 101, so that the surface of the ink printing roller can be soaked in the cleaning chamber 101, and then cleaned by the ultrasonic cleaning liquid inside the cleaning box 1 (this is the existing ultrasonic cleaning method, so it will not be described in detail).

[0036] Through the above steps, no matter how long or thick the ink printing roller that needs to be cleaned is, it can be placed on the support assembly first, and then cleaned through the lifting mechanism, moving mechanism and rotating assembly, which is more practical.

[0037] Please refer to Figure 2-Figure 4 , Figure 6 and Figure 7 The transmission mechanism includes a rotating motor 8, a main gear 10 and two slave gears 7. The outer wall of the rotating motor 8 is fixedly connected to the outer wall of the cleaning box 1. The output shaft of the rotating motor 8 passes through the outer wall of the cleaning box 1 and is fixedly connected to one side of the main gear 10. The main gear 10 is meshed with the two slave gears 7. The sides of the two slave gears 7 close to the rotating motor 8 are rotatably connected to the inner wall of the cleaning chamber 101, and the other sides of the two slave gears 7 are connected to one of the rotating components.

[0038] More specifically, when it is necessary to control the rotation of the rotating component, the rotating motor 8 is started by the control button on the control box 2. After the rotating motor 8 is started, the output shaft drives the main gear 10 to rotate. After the main gear 10 rotates, it drives the two slave gears 7 to rotate through meshing, and then can drive a group of connected rotating components to rotate.

[0039] Please refer to Figure 2-Figure 4 , Figure 6 and Figure 7 The moving mechanism includes a moving motor 9, a threaded rod 12 and an I-shaped bracket 3. The outer wall of the moving motor 9 is fixedly connected to the outer wall of the cleaning box 1. The output shaft of the moving motor 9 passes through the cleaning box 1 and is fixedly connected to one end of the threaded rod 12. The other end of the threaded rod 12 passes through the I-shaped bracket 3 and is rotatably connected to the inner wall on the other side of the cleaning chamber 101. The outer wall of the threaded rod 12 is threadedly connected to the penetration point of the I-shaped bracket 3. The bottom surface of the I-shaped bracket 3 is slidably connected to the bottom surface of the cleaning chamber 101. The end of the I-shaped bracket 3 away from the threaded rod 12 is connected to another rotating component.

[0040] More specifically, when it is necessary to control the movement of the rotating component close to the control box 2, the moving motor 9 is started by the control button on the control box 2. After the moving motor 9 is started, it drives the threaded rod 12 to rotate. After the threaded rod 12 rotates, it can drive the I-shaped bracket 3 with a surface thread connection to move along the thread, and then drive the rotating component on the I-shaped bracket 3 to move.

[0041] Please refer to Figure 1-Figure 4 , Figure 6 and Figure 7 The two sets of rotating components each include two rotating wheels 4. The two rotating wheels 4 close to the rotating motor 8 are respectively fixedly connected to the two sides of the gear 7 away from the rotating motor 8. The two rotating wheels 4 close to the I-shaped bracket 3 are respectively rotatably connected to the two sides of the upper end of the I-shaped bracket 3. The two ends of the printing roller are respectively placed between the two rotating wheels 4 on both sides.

[0042] More specifically, when the ink printing roller is placed between the four rotating wheels 4, the two slave gears 7 rotate, which in turn can drive the two rotating wheels 4 to rotate. After the two rotating wheels 4 rotate, they will drive the middle ink printing roller to rotate, which can drive the two rotating wheels 4 on the other side to rotate together, so that the ink printing roller can maintain a uniform rotation in the cleaning chamber 101, so that the ink adhering to the surface can be cleaned by ultrasound.

[0043] Please refer to Figure 4 , Figure 6 and Figure 7 An auxiliary rod 14 is fixedly connected to the inner wall of the cleaning chamber 101. The auxiliary rod 14 passes through the lower end of the I-shaped bracket 3. The auxiliary rod 14 is arranged parallel to the threaded rod 12 and is respectively located on both sides of the lower end of the I-shaped bracket 3. The auxiliary rod 14 is slidably connected to the penetration point of the I-shaped bracket 3.

[0044] More specifically, by providing the auxiliary rod 14, firstly, the other end of the I-shaped bracket 3 can be supported to prevent the I-shaped bracket 3 from idling, and secondly, a supporting force can be provided at the other end of the I-shaped bracket 3 to achieve a better supporting effect.

[0045] Please refer to Figure 5 The lifting mechanism includes a hydraulic rod 13 and a support block 15. The outer wall of the hydraulic rod 13 is fixedly connected to the bottom surface of the cleaning chamber 101, the output end of the hydraulic rod 13 is fixedly connected to the bottom surface of the support block 15, and the upper surface of the support block 15 is connected to the support assembly.

[0046] More specifically, when it is necessary to control the lifting of the support assembly and the ink printing roller in the cleaning chamber 101, the hydraulic rod 13 is first started through the control button on the control box 2. After the hydraulic rod 13 is started, the output end is extended or retracted, and then the upper support block 15 can be driven to lift in the cleaning chamber 101, thereby driving the support assembly and the ink printing roller above the support block 15 to lift.

[0047] Please refer to Figure 1-Figure 5The support assembly includes a support plate 5 and a plurality of rollers 6. The cross section of the support plate 5 is V-shaped. The outer wall of the support plate 5 is connected to the support block 15. The plurality of rollers 6 are rotatably connected to the inner wall of the support plate 5. The outer wall of the printing roller is against the surface of the plurality of rollers 6.

[0048] More specifically, when the ink printing roller needs to be cleaned, the ink printing roller is first placed on the support plate 5 and a plurality of rollers 6. Since the cross section of the support plate 5 is V-shaped, no matter how thick or thin it is, it will slide under the support plate 5 due to gravity, thereby automatically keeping the ink printing roller in a horizontal state. When the ink printing roller needs to be pushed to move, the sliding friction is smaller due to the action of the rollers 6, thereby achieving more convenient movement.

[0049] Please refer to Figure 5 Both sides of the outer wall of the support plate 5 are fixedly connected with slide rails 16 , and the upper surface of the support block 15 is penetrated with two slide grooves 1501 , and the outer walls of the two slide rails 16 are slidably connected with the inner walls of the two slide grooves 1501 .

[0050] More specifically, because some ink printing rollers are shorter, when the ink printing roller is initially aligned with the rotating component on the side close to the control box 2, the support plate 5 can be moved toward the side of the control box 2 through the slide rail 16 and the slide groove 1501. When the ink printing roller on this side is stuck between the wheels 4, the moving mechanism drives the two wheels 4 and the I-shaped bracket 3 on this side to move. As the I-shaped bracket 3 moves, the support plate 5 will be pushed toward the direction of the rotating motor 8. In this way, when adapting to the support of ink printing rollers with longer lengths, it will not affect the subsequent support.

[0051] Please refer to Figure 3-Figure 5 A waterproof cover 11 is fixedly connected to the bottom surface of the cleaning chamber 101 , a hydraulic rod 13 is located inside the waterproof cover 11 , and an output end of the hydraulic rod 13 passes through the waterproof cover 11 .

[0052] More specifically, since cleaning fluid is provided inside the cleaning chamber 101 and the hydraulic rod 13 is located inside the cleaning chamber 101 , the probability of damage to the hydraulic rod 13 can be reduced by providing the waterproof cover 11 .

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
