Description

Technical Field

[0001] The invention relates to the technical field of printing roller cleaning devices, in particular to a surface cleaning device for a self-adhesive label printing roller. Background Art

[0002] Compared to traditional labels, self-adhesive labels have the advantages of eliminating the need for glue, paste, or water, resulting in a pollution-free, time-saving application. They are widely applicable and quick and easy to apply. Self-adhesive labels, also known as self-adhesive label materials, are a composite material made of paper, film, or other specialty materials, with an adhesive coating on the back and a silicone-coated protective paper as the backing. After printing and die-cutting, they become finished labels.

[0003] According to Chinese patent CN214774827U, a device for cleaning the surface of a self-adhesive label printing roller is proposed. By arranging structures such as a cleaning ring, a cleaning brush, a synchronous rack, a synchronous shaft, a drive motor, a threaded column, a synchronous sleeve, a synchronous column, a synchronous ring and a supporting plate, when the drive motor drives the cleaning brush at the cleaning ring to clean the printing roller, the drive motor can synchronously drive the synchronous ring to move, thereby driving the printing roller to move, thereby achieving the effect of cleaning and moving the printing roller.

[0004] There are still some shortcomings in the printing roller surface cleaning device in the existing technology. When the printing roller surface is cleaned by a cleaning brush, since the cleaning position of the cleaning brush on the printing roller surface cannot be adjusted, the cleaning brush is likely to cause omissions of local positions on the printing roller surface during the cleaning process, resulting in failure to clean the surface, affecting the cleaning effect of the printing roller. For this reason, we propose a self-adhesive label printing roller surface cleaning device. Summary of the Invention

The adjusting assembly 41 is provided, and when the printing roller body 3 needs to be cleaned, in order to evenly clean the surface of the printing roller body 3 and improve the cleaning effect, it is necessary to adjust the rotation angle of the printing roller body 3 during the cleaning process. First, the operator installs the printing roller body 3 to the outer wall of the rotating shaft 417. Then, during the cleaning process, the operator turns on the driving motor 412 to cause the first rotating frame 413 to rotate. During the rotation of the first rotating frame 413, the second rotating frame 414 is squeezed, causing the second rotating frame 414 to rotate slowly. During the slow rotation of the second rotating frame 414, the rotating rod 415 is driven to rotate. After the rotating rod 415 rotates, the rotating shaft 417 is driven to rotate.

[0022] Example 2 The difference from Example 1 is that this embodiment discloses a cleaning component, such as Figure 5 - Figure 7 As shown; A cleaning assembly 42 is also provided above the mounting plate 1. The cleaning assembly 42 includes a second support frame 421 fixedly connected to the top of the mounting plate 1. The top inner wall of the second support frame 421 is fixedly connected to a rectangular frame 422. One side of the rectangular frame 422 is fixedly connected to a forward and reverse motor 423. The output end of the forward and reverse motor 423 is fixedly connected to a screw rod 424. The screw rod 424 is movable through the outside of the rectangular frame 422 and extends to the inside of the rectangular frame 422. The other end of the screw rod 424 is fixed to the inner wall of the rectangular frame 422. The outer wall of the screw rod 424 is threadedly connected to a socket block 425, and the bottom of the socket block 425 is fixedly connected to a rectangular frame 426. The inner walls of both sides of the rectangular frame 426 are provided with a slide groove 427. The inner wall of the slide groove 427 is fixedly connected to a fixed rod 428. The outer wall of the fixed rod 428 is slidably connected to a displacement block 429. The top of the displacement block 429 is fixedly connected to a second spring 4211. The other end of the second spring 4211 is fixedly connected to the top of the inner wall of the slide groove 427. The side wall of the displacement block 429 is fixed. A brush plate 4210 is connected, and the bottom of the brush plate 4210 is slidably connected to the surface of the printing roller body 3. By setting the cleaning component 42, when the printing roller body 3 needs to be cleaned, the operator presses the two brush plates 4210 to cause the displacement block 429 to move along the outer wall of the fixed rod 428 and compresses the second spring 4211, and then places the two brush plates 4210 on the outer wall of the printing roller body 3. During the cleaning process, the operator starts the forward and reverse motor 423 to cause the screw rod 429 to move along the outer wall of the fixed rod 428. 424 rotates. During the rotation of the screw rod 424, the sleeve block 425 is limited by the interior of the rectangular frame 422, which prompts the sleeve block 425 to move along the outer wall of the screw rod 424. During the movement of the sleeve block 425, the rectangular frame 426 is driven to move. During the movement of the rectangular frame 426, the two brush plates 4210 are driven to move. During the movement of the two brush plates 4210, the surface of the printing roller body 3 can be cleaned. The bottom side of the sleeve block 425 is fixedly connected with a fixed seat 4212, the inner wall of the side of the fixed seat 4212 is fixedly connected with a water tank 4213, the bottom of the water tank 4213 is fixedly connected with a water pump 4214, the input end of the water pump 4214 is connected to the bottom of the water tank 4213, the output end of the water pump 4214 is connected to a spray head 4215, and the spray head 4215 is located above the printing roller body 3. When the sleeve block 425 moves, it will also drive the fixed seat 4212 and the storage tank 4213 to move. The water tank 4213, the water pump 4214, and the spray head 4215 move. When the brush plate 4210 is cleaning the printing roller body 3, the operator turns on the water pump 4214, prompting the water pump 4214 to pump water from the water tank 4213 into the spray head 4215 and discharge the water through the spray head 4215, thereby spraying the surface of the printing roller body 3.

An L-shaped plate 4216 is fixedly connected to the other side of the sleeve block 425, and a fixing ring 4217 is fixedly connected to the other end of the L-shaped plate 4216. The inner wall of the fixing ring 4217 is fixedly connected to an annular dryer 4218, and the outer wall of the fixing ring 4217 is fixedly connected to a controller 4219. When the brush plate 4210 cleans the surface of the printing roller body 3, when the sleeve block 425 moves, it also drives the L-shaped plate 4216 to move. When the brush plate 4210 finishes cleaning the surface of the printing roller body 3, the operator turns on the controller 4219 to start the annular dryer 4218.

By providing the rectangular frame 422 on the outer wall of the sleeve block 425, the sleeve block 425 can be limited. When the screw rod 424 rotates, the sleeve block 425 can be moved along the outer wall of the screw rod 424, thereby adjusting the cleaning position of the surface of the printing roller body 3; There are four second support frames 421 , which are located at the bottom of the four corners of the rectangular frame 422 . By arranging four second support frames 421 at the bottom of the rectangular frame 422 , the rectangular frame 422 can be stably supported, thereby improving the stability of the rectangular frame 422 .

[0023] Working principle: when the printing roller main body 3 needs to be cleaned, in order to be able to evenly clean the surface of the printing roller main body 3 and improve the cleaning effect, it is necessary to adjust the rotation angle of the printing roller main body 3 during the cleaning process. First, the operator first installs the printing roller main body 3 to the outer wall of the rotating shaft 417. Then, during the cleaning process, the operator turns on the driving motor 412 to cause the first rotating frame 413 to rotate. During the rotation of the first rotating frame 413, the second rotating frame 414 is squeezed, causing the second rotating frame 414 to rotate slowly. During the slow rotation of the second rotating frame 414, the rotating rod 415 is driven to rotate. After the rotating rod 415 rotates, the rotating shaft 417 is driven to rotate. During the rotation of the rotating shaft 417, the printing roller main body 3 fixed on its outer wall is driven to rotate slowly. During the cleaning process of the printing roller main body 3, the surface of the printing roller main body 3 can be evenly cleaned, thereby improving the cleaning effect of the printing roller main body 3. When the printing roller body 3 needs to be fixedly installed on the outer wall of the rotating shaft 417, the operator presses the pressing block 419 to cause the pressing block 419 to move along the inner wall of the rectangular groove 418. During the movement of the pressing block 419, the sleeve block 4110 is driven to move along the outer wall of the limiting rod 4111. After the sleeve block 4110 moves, it squeezes the first spring 4114. Subsequently, the operator sleeves the printing roller body 3 on the outer wall of the rotating shaft 417 so that one end of the printing roller body 3 fits with the side wall of the vertical plate 416. When the printing roller body 3 is fixed on the outer wall of the rotating shaft 417, the operator presses the pressing block 419 to cause the pressing block 419 to move along the inner wall of the rectangular groove 418. After the printing roller body 3 is installed on the outer wall of the rotating shaft 417, the operator releases the pressing block 419. Under the reaction of the first spring 4114, the pressing block 419 is reset, causing the top side wall of the pressing block 419 to squeeze the other end of the printing roller body 3, thereby fixing the printing roller body 3. After the printing roller body 3 is fixed, the rotating shaft 417 rotates, which can drive the printing roller body 3 on its outer wall to rotate, so that when cleaning the printing roller body 3, the surface of the printing roller body 3 can be fully cleaned. When it is necessary to clean the printing roller main body 3, the operator presses the two brush plates 4210 to prompt the displacement block 429 to move along the outer wall of the fixed rod 428 and compress the second spring 4211, and then places the two brush plates 4210 on the outer wall of the printing roller main body 3. During the cleaning process, the operator starts the forward and reverse motor 423 to prompt the screw rod 424 to rotate. During the rotation of the screw rod 424, the sleeve block 425 is limited by the interior of the rectangular frame 422, which will prompt the sleeve block 425 to move along the outer wall of the screw rod 424. During the movement of the sleeve block 425, the rectangular frame 426 is driven to move. During the movement of the rectangular frame 426, the two brush plates 4210 are driven to move. During the movement of the two brush plates 4210, the surface of the printing roller main body 3 can be cleaned. When the sleeve block 425 moves, it also drives the L-shaped plate 4216 to move. When the brush plate 4210 finishes cleaning the surface of the printing roller body 3, the operator turns on the controller 4219 to start the annular dryer 4218. When the annular dryer 4218 is started, the surface of the printing roller body 3 can be dried, thereby improving the use effect of the device. When the sleeve block 425 moves, it will also drive the L-shaped plate 4216 to move. When the brush plate 4210 finishes cleaning the surface of the printing roller body 3, the operator turns on the controller 4219 to start the annular dryer 4218.
