[0022] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a cleaning device for a printing roller provided by the present invention; Figure 2 for Figure 1 A schematic structural diagram of the front view of the device shown; Figure 3 for Figure 1 A schematic structural diagram of a right side cross-sectional view of the chassis portion shown; Figure 4 for Figure 1 The schematic diagram of the structure of the placement frame is shown, which shows a cleaning device for a printing roller, comprising: a base frame 1, a cleaning component 2 is provided on the top of the base frame 1, and a fixing component 3 is provided on the top of the base frame 1 and above the cleaning component 2;

[0024] The cleaning assembly 2 includes a water reservoir 21 disposed on the top of the base frame 1. A first guide roller 22 is rotatably disposed on the inner side of the water reservoir 21. Support frames 23 are disposed on the left and right sides of the top of the base frame 1. Two second guide rollers 24 are rotatably disposed on the inner side of the support frames 23. A cleaning cloth 25 is sheathed on the outer side of the first guide roller 22 and the two second guide rollers 24.

[0025] The two second guide rollers 24 are used to stretch the top of the cleaning cloth 25, and the first guide roller 22 is used to immerse the bottom of the cleaning cloth 25 in water, thereby forming a similar triangular shape. When the printing roller is on the top of the cleaning cloth 25, the output end of the drive motor 26 rotates to drive the two second guide rollers 24 to rotate, and then drives the cleaning cloth 25 to rotate, so that the surface of the printing roller can be cleaned.

[0026] The fixing component 3 includes a placement rack 31 arranged on the top of the base frame 1, and a sliding plate 32 is provided on the inner side of the placement rack 31 so as to slide up and down. Brackets 33 are provided on the left and right sides of the bottom of the sliding plate 32. The left bracket 33 is provided on the bottom of the sliding plate 32 so as to slide left and right. The top of the right bracket 33 is fixedly connected to the bottom of the sliding plate 32, and a printing roller body 34 is provided on the opposite side of the two brackets 33.

[0027] By setting the left bracket 33 that can slide left and right, the fixed component 3 is suitable for printing rollers of different lengths. Through the setting of the bracket 33, when in use, the printing roller body 34 can be hung on the inner side of the two brackets 33 (because the bottom cleaning cloth 25 is attached to the bottom of the printing roller body 34, and the surface of the printing roller body 34 often has lines, then under the action of friction, when the cleaning cloth 25 rotates, it will drive the printing roller body 34 to rotate slowly).

[0028] A drive motor 26 is provided on the inner side of the base frame 1 , and the output end on the left side of the drive motor 26 passes through the inner side of the base frame 1 and extends to its left side. The output end on the left side of the drive motor 26 is connected to the left end belts of the two second guide rollers 24 .

[0029] A sliding rod 35 is provided on the inner side of the placement rack 31, and a sliding block 36 is provided on the peripheral side of the sliding rod 35 so as to slide left and right along its length direction. A rotating plate 37 is provided on the bottom of the sliding block 36 so as to be rotatable. The bottom of the rotating plate 37 is rotatably connected to the top of the sliding plate 32.

[0030] By extending and retracting the telescopic end of the first cylinder 38, the rotating plate 37 at the bottom of the sliding block 36 rotates, and in conjunction with the setting of the sliding plate 32 that can only slide up and down, when the telescopic end of the first cylinder 38 is extended, the sliding plate 32 descends, and at this time the bottom of the printing roller body 34 is able to fit on the top of the cleaning cloth 25. Conversely, when the sliding plate 32 rises, the printing roller body 34 can be removed and placed.

[0031] A first cylinder 38 is provided on the top of the placement rack 31 , and the telescopic end on the right side of the first cylinder 38 is fixedly connected to the top of the left side of the sliding block 36 .

[0032] A second cylinder 39 is provided on the left side of the top of the sliding plate 32 , and the telescopic end on the left side of the second cylinder 39 is fixedly connected to the top of the right side of the left bracket 33 .

[0033] A drain outlet 27 is provided on the front of the water reservoir 21 , and reinforcement frames 28 are provided on both the front and rear sides of the base frame 1 .

[0034] The working principle of the cleaning device for a printing roller provided by the utility model is as follows:

[0035] Step 1: When in use, determine the position of the left bracket 33 according to the actual length of the embossing roller body 34, then hang the two ends of the embossing roller body 34 on the inner sides of the two brackets 33, and extend the output end of the first cylinder 38 to drive the sliding plate 32 downward, so that the bottom of the embossing roller body 34 is in contact with the top of the cleaning cloth 25;

[0036] Step 2: After adding cleaning agent or clean water to the water reservoir 21, the two second guide rollers 24 are driven to rotate by controlling the rotation of the output end of the drive motor 26. The rotation of the two second guide rollers 24 drives the cleaning cloth 25 covering the circumferential side thereof to rotate. When the cleaning cloth 25 rotates, it drives the printing roller body 34 to rotate slowly under the action of friction. At the same time, the rotating cleaning cloth 25 cleans the printing roller body 34. By setting the first guide roller 22, the lower part of the cleaning cloth 25 is located inside the water reservoir 21, so that the cleaning cloth 25 remains in a relatively clean state, thereby ensuring the cleaning effect of the printing roller;

[0037] Step 3: After cleaning is completed, the first cylinder 38 can be controlled to lift the sliding plate 32, and then the printing roller body 34 can be removed. It can also be dried with a drying device to achieve a better cleaning effect.

[0038] Compared with the related art, the cleaning device for a printing roller provided by the present invention has the following beneficial effects:

[0039] By controlling the rotation of the output end of the drive motor 26, the two second guide rollers 24 are driven to rotate. The rotation of the two second guide rollers 24 will drive the cleaning cloth 25 covering the peripheral side thereof to rotate. When the cleaning cloth 25 rotates, it will drive the printing roller body 34 to rotate slowly under the action of friction. At the same time, the rotating cleaning cloth 25 will clean the printing roller body 34. Through the setting of the first guide roller 22, the lower part of the cleaning cloth 25 is located in the water reservoir 21, so that the cleaning cloth 25 maintains a cleaning effect. The structure is simple and practical, can replace manual cleaning of the printing roller, and improves the cleaning efficiency.

[0040] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations. Any simple modifications, equivalent variations, and modifications to the above embodiments based on the technical essence of the present invention shall be deemed to fall within the scope of protection of the present invention.
