[0001] The utility model relates to the technical field of thin film printing roller cleaning, in particular to a printing roller cleaning device. Background Technique

[0002] When processing plastic films such as plastic bags, the patterns on the film surface are processed by a printing and drying machine. Mainly, after the printing roller dips in the ink, it is pressed onto the film. After the printing roller finishes working or when different types of ink need to be replaced, it needs to be cleaned before being installed. However, the existing cleaning method mainly relies on manual cleaning. Since the ink on the surface of the printing roller has high viscosity and needs to be cleaned with alcohol to clean the roller surface completely, it is time-consuming and laborious.

[0003] Therefore, we designed a cleaning device for the printing roller. By placing the printing roller in the cleaning box and through the cooperation of the brush roller and the alcohol self-spraying component, the automatic cleaning of the printing roller can be realized. Moreover, this device is applicable to printing rollers of different models, effectively reducing the labor intensity of the staff and improving the cleaning efficiency of the printing roller.

This driving assembly is a conventional general design familiar to those skilled in the art, and will not be elaborated in this application.

[0022] It should be noted that the above-mentioned printing roller 2 is a common roller structure in the printing and drying machines in this field. The connection methods of the printing roller fixing cylinder 12 and the top shaft 11 to the printing roller 2 are conventional and general designs, and their installation principles in the printing and drying machine are the same as that of the printing roller 2. The end of the top shaft 11 and the shaft hole at one end of the printing roller 2 can be designed as corresponding cross shapes, so as to realize the plug-in fixation of the two. When installing the printing roller 2, first dock one end of the printing roller 2 with the top shaft 11, and then control the printing roller fixing cylinder 12 to make its output end push into the other end of the printing roller 2 to tighten the printing roller 2, thus realizing the installation of the printing roller 2. When disassembling, only need to retract the output end of the printing roller fixing cylinder 12, and then pull out the printing roller 2 from the top shaft 11, which is a conventional operation and will not be elaborated in this application.

[0023] As Figures 1-4 shown, a brush roller 3 is arranged on one side of the printing roller 2 in the cleaning box 1. The distance between the brush roller 3 and the printing roller 2 can be adjusted, and a brush roller driving assembly for driving the brush roller 3 to rotate is arranged in the cleaning box 1. Specifically, corresponding first guide rails 5 are arranged on both sides inside the cleaning box 1, and first sliders 6 are slidably arranged on the first guide rails 5. The brush roller 3 is rotatably arranged between the two first sliders 6. It should be noted that the brush roller 3 is a roller with bristles designed on its surface, which is a conventional structure and will not be elaborated in this application. In order to realize the adjustable distance between the brush roller 3 and the printing roller 2 so that the brush roller 3 can adapt to printing rollers 2 with different diameters, as Figure 1 、 Figure 4 shown, a brush roller transverse movement cylinder 13 is fixedly arranged on the inner wall of the cleaning box 1, and the output end of the brush roller transverse movement cylinder 13 is connected to one of the first sliders 6; as Figure 3 shown, as a conventional driving design familiar to those skilled in the art, the brush roller driving assembly includes a second pneumatic motor 20 arranged on the first slider 6. The output end of the second pneumatic motor 20 is connected with a third pulley 21, and a fourth pulley 22 is arranged on the roller shaft of the brush roller 3. The third pulley 21 drives the fourth pulley 22 to rotate through a second transmission belt 23.

[0024] It should be noted that the positional relationships between the first guide rail 5 and components such as the fixing plate 25, the printing roller fixing cylinder 12, and the brush roller transverse movement cylinder 13 in this application should be conventional designs familiar to those skilled in the art. During actual assembly, they can be assembled in the cleaning box 1 according to the actual size relationships of the components, and no further limitations will be elaborated in this application.

[0025] In addition, as Figure 1 、 Figure 2 and Figure 4As shown in the figure, an alcohol self-spraying component 4 for spraying alcohol onto the printing roller 2 is further provided in the cleaning tank 1. The component includes a support plate 14 fixedly arranged between two first sliders 6. The support plate 14 is located above the brush roller 3. A second guide rail 15 is arranged at the upper end of the support plate 14. A second slider 16 is slidably arranged on the second guide rail 15. An alcohol spray pipe 17 is arranged on the side of the second slider 16 close to the printing roller 2. A spray pipe moving cylinder 19 is arranged on the support plate 14. The output end of the spray pipe moving cylinder 19 is connected to the second slider 16. It should be noted that as a conventional design, the alcohol spray pipe 17 should be connected to an alcohol tank through a hose, and alcohol is provided to the alcohol spray pipe 17 by a liquid pump or pressurizing the alcohol tank. At the same time, spray holes are opened on the alcohol spray pipe 17 or a spray head 18 is designed to achieve the spraying of alcohol, which is a conventional design familiar to those skilled in the art and will not be elaborated in this application.

[0026] In practical applications, an openable and closable lid should be designed at the top of the cleaning tank 1 to prevent alcohol from splashing outside during the cleaning process. This is a conventional design and will not be elaborated. When in use, the printing roller 2 is installed in the cleaning tank 1. Driven by the starting motor, the printing roller 2 and the brush roller 3 rotate in opposite directions. At the same time, the brush roller transverse movement cylinder 13 pulls the brush roller 3 closer to the printing roller 2, so that the bristles on the brush roller 3 contact the surface of the printing roller 2. At the same time, the spray pipe moving cylinder 19 drives the drain pipe 24 to reciprocate, and the drain pipe 24 sprays alcohol onto the surface of the printing roller 2 to clean the ink on the surface of the printing roller 2. The cleaned liquid can be discharged through the drain pipe 24.

[0027] It should be noted that the pneumatic motor and the cylinder should also be connected to corresponding air pipes. The layout of the air pipes is a conventional operation familiar to those skilled in the art and will not be elaborated in this application.

[0028] It should be noted that since the cleaning material alcohol is a flammable and explosive liquid, all pneumatic drives are adopted inside the cleaning tank. At the same time, as a conventional design, a box door should be arranged at the upper end of the box body, and a central control console should be arranged outside to control each electrical component. This design is common knowledge familiar to those skilled in the art and will not be elaborated in this application.

[0029] It should be noted that the above embodiments only specifically and clearly describe the technical solutions and technical features of this application.
