Technical Field

[0001] The utility model belongs to the technical field of thin film printing, and particularly relates to a cleaning device for a printing roller used for thin film printing. Background Technique

[0002] Plastic films are most widely used in the packaging field, and plastic films need to be color-printed. Printing rollers are mainly divided into two categories: hard rollers and soft rollers, which are used in printing machinery as rubber rollers for imprinting, ink mixing, and ink transfer. Such rubber rollers have appropriate hardness and elasticity, high oil resistance, resistance to washing solvents, wear resistance, and shape stability.

[0003] After the printing roller is used for a long time, it usually needs to be cleaned on the surface by a cleaning device. The existing cleaning device usually places the printing roller on a driving wheel, drives the printing roller to rotate through the driving wheel, and then cleans the surface of the printing roller through a cleaning brush. This rotation method is prone to slipping, resulting in the problem that the rotation of the printing roller is interrupted during the cleaning process, thereby reducing the cleaning efficiency of the printing roller.

[0026] Please refer to Figures 1-5As shown in the figure, the utility model is a cleaning device for a printing roller used in film printing, which includes a cleaning box body 1. A printing roller 11 is arranged on the top of the cleaning box body 1. A pressing component 12 is arranged on the right side of the top of the cleaning box body 1. A cleaning component 13 is arranged in front of the printing roller 11. Two driving wheels 16 are arranged on the left side and the right side of the bottom of the cleaning box body 1 respectively. The number of the driving wheels 16 is four. Protrusions 161 are fixedly connected to the outer surfaces of the four driving wheels 16; The pressing component 12 includes a fixing frame 121. A lifting seat 122 is arranged on the right side above the printing roller 11. A threaded hole is formed inside the fixing frame 121. A threaded rod 123 is threadedly connected to the inner wall of the threaded hole. A limiting ring 222 is fixedly connected to the top of the lifting seat 122. The inner wall of the limiting ring 222 is rotatably connected to the bottom of the threaded rod 123. Two rollers 221 are rotatably connected to the bottom of the lifting seat 122. By setting the pressing component 12, specifically after the printing roller 11 is placed, turning the handle 124 clockwise drives the threaded rod 123 to move downward, then the lifting seat 122 moves downward. When the rollers 221 at the bottom of the lifting seat 122 contact the surface of the printing roller 11, stop turning the handle 124. At this time, the printing roller 11 will be pressed, which can make the printing roller 11 closely adhere to the driving wheel 16, so that there will be no slipping during the rotation process. At the same time, the protrusions 161 arranged on the surface of the driving wheel 16 can increase the friction force, and prevent slipping again, so that the printing roller 11 rotates more stably and the cleaning efficiency is improved; A motor 15 is fixedly connected to the right side of the cleaning box body 1. The inner walls of the four driving wheels 16 are all rotatably connected to a rotating shaft 162. The four rotating shafts 162 are all rotatably connected to the cleaning box body 1. The right side of the rotating shaft 162 located in the front right is fixedly connected to the left output end of the motor 15. Starting the motor 15 drives the rotating shaft 162 in the front right to rotate, then the driving wheel 16 in the front right rotates accordingly, thereby driving the printing roller 11 to rotate; The outer surface of the roller 221 is in contact with the outer surface of the printing roller 11. A connecting rod 125 is fixedly connected to the back of the lifting seat 122. A limiting rod 126 is fixedly connected to the top of the connecting rod 125. The top of the limiting rod 126 penetrates through the fixing frame 121 and extends to the outside. The limiting rod 126 is slidably connected to the fixing frame 121. When the lifting seat 122 moves, it will drive the limiting rod 126 to slide on the fixing frame 121 through the connecting rod 125, which is used to limit the lifting seat 122 and prevent the lifting seat 122 from shifting;The cleaning component 13 includes a cleaning brush 131. A cross bar 132 is arranged in front of the cleaning brush 131. Both the left side and the right side of the cross bar 132 are fixedly connected to the inner wall of the cleaning box body 1. A moving block 133 is arranged above the cross bar 132. A slider 134 is fixedly connected to the bottom of the moving block 133. A sliding rod 135 is fixedly connected to the front surface of the cleaning brush 131. By arranging the cleaning component 13, specifically, the worker pushes the moving block 133, then the square sliding groove 341 inside the slider 134 slides on the cross bar 132, and the left and right positions of the cleaning brush 131 can be adjusted. By pushing and pulling the sliding rod 135, the front and back positions of the cleaning brush 131 can be adjusted. The worker can move the cleaning brush 131 arbitrarily to clean different positions of the printing roller 11, which not only reduces the occurrence of dead corners, but also improves the cleaning effect in this way. A sliding hole 331 is formed inside the moving block 133, and a square sliding groove 341 is formed inside the slider 134. The inner wall of the sliding hole 331 is slidably connected to the outer surface of the sliding rod 135, and the inner wall of the square sliding groove 341 is slidably connected to the outer surface of the cross bar 132. The square sliding groove 341 enables the slider 134 to move linearly on the cross bar 132. A diversion groove 14 is fixedly connected to the inner wall of the cleaning box body 1. The front of the diversion groove 14 penetrates through the cleaning box body 1 and extends to the outside. The front surface of the sliding rod 135 is convexly arranged. Since the front surface of the sliding rod 135 is convexly arranged, the sliding rod 135 can be prevented from falling off. The cleaned stains then fall on the diversion groove 14.;

[0027] A specific application of this embodiment is as follows:

[0028] During use, place the printing roller 11 on top of the cleaning box body 1 so that the surface of the printing roller 11 contacts the surface of the driving wheel 16. Then, rotate the turning handle 124 clockwise to drive the threaded rod 123 to move downward. The bottom of the threaded rod 123 rotates within the limit ring 222, and the threaded rod 123 drives the lifting seat 122 to move downward. At the same time, the lifting seat 122 drives the limit rod 126 to slide on the fixed frame 121 through the connecting rod 125, which plays a role in limiting the lifting seat 122 and preventing the lifting seat 122 from shifting. When the roller 221 at the bottom of the lifting seat 122 contacts the surface of the printing roller 11, stop rotating the turning handle 124. At this time, the printing roller 11 will be pressed, enabling the printing roller 11 to be in close contact with the driving wheel 16, so that there will be no slipping during the rotation process. At the same time, the convex blocks 161 provided on the surface of the driving wheel 16 can increase the friction force and prevent slipping again, thereby enabling the printing roller 11 to rotate more stably and improving the cleaning efficiency. By starting the motor 15 to drive the rotation of the rotating shaft 162 in the front right, the driving wheel 16 in the front right will follow the rotation, thereby driving the printing roller 11 to rotate. When the printing roller 11 rotates, the roller 221 will rotate within the lifting seat 122. The roller 221 presses the printing roller 11 without affecting the rotation of the printing roller 11. Then, the staff pushes the moving block 133, and the moving block 133 slides on the cross bar 132 through the square chute 341 inside the slider 134, which can adjust the left and right positions of the cleaning brush 131. By pushing and pulling the sliding rod 135, the sliding rod 135 slides within the sliding hole 331 in the moving block 133 to adjust the front and back positions of the cleaning brush 131. The staff can arbitrarily move the position of the cleaning brush 131 to clean different positions of the printing roller 11, not only reducing the occurrence of dead corners, but also improving the cleaning effect in this way. The stains after cleaning will fall on the diversion groove 14 and then be discharged outside the cleaning box body 1 from the diversion groove 14.
