[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] like Figure 1 As shown, the present application provides a printing roller cleaning device, including a frame 1, on which a fixing component 2 is arranged, the fixing component 2 is used to fix the printing roller, and a cleaning component 3 is fixedly installed on the frame 1, the cleaning component 3 is used to clean the printing roller and switch the cleaning position at the same time;

[0028] like Figure 1 and Figure 3As shown, the fixing assembly 2 includes a plurality of mounting plates 25 arranged on the frame 1, and a mounting box 21 is fixedly mounted on the mounting plate 25, a rotating rod 22 is mounted on the internal bearing of the mounting box 21, and a latch 23 is fixedly mounted on one end of the rotating rod 22, and the latch 23 is used to clamp the printing roller. It should be noted that a socket matched with the latch 23 is provided at the end of the printing roller, so that the printing roller can be rotated and limited by the latch 23;

[0029] In the present application, a driving motor may be provided at the other end of the rotating rod 22 to drive the printing roller to rotate, and a roller support frame 24 is fixedly mounted on the mounting plate 25, and two groups of rotatable rollers are provided on the roller support frame 24 to facilitate the placement of the printing roller, and the printing roller can rotate on the two groups of rollers;

[0030] In summary, when fixing the printing roller, the printing roller is placed on the upper end of the two sets of rollers, and the latch 23 is inserted into the insertion hole of the printing roller, and then the motor is driven to rotate and drive the rotating rod 22 to rotate synchronously with the printing roller;

[0031] like Figure 1 As shown, at least two groups of fixed components 2 are provided to realize continuous operation of the cleaning component 3, and the multiple groups of fixed components 2 are arranged along the vertical direction (refer to Figure 1 ), so that the multiple groups of fixed components 2 form at least two groups of fixed stations. For the convenience of description, two groups of fixed components 2 are provided in the present application, thereby forming two groups of fixed stations, which are respectively defined as the first station and the second station;

[0032] like Figure 1 As shown, the cleaning assembly 3 includes a group of transmission assemblies 31, and the transmission assembly 31 includes a slide rail 43 fixedly mounted on the frame 1, and the slide rail 43 is arranged along the length direction of the printing roller, and a fixed frame 32 is slidably arranged on the slide rail 43. In the present application, in order to drive the fixed frame 32 to move on the slide rail 43, an electric cylinder can be used to push, that is, the electric cylinder is fixed on the frame 1, and then the output end of the electric cylinder is connected to the fixed frame 32, so that the translational sliding of the fixed frame 32 is realized through the extension and contraction of the electric cylinder;

[0033] like Figure 2 and Figure 4 As shown, the cleaning assembly 3 also includes a cylinder 33 fixedly mounted on a fixing frame 32, a push rod 34 is fixedly mounted on the output end of the cylinder 33, a mounting block (not shown in the figure) is fixedly mounted on the push rod 34, and a cleaning cotton (not shown in the figure) is fixedly mounted on the mounting block;

[0034] In summary, multiple groups of printing rollers are fixed by the fixing component 2, and then the lifting component is driven to move back and forth by the transport component, thereby driving the cleaning cotton to move back and forth, so as to clean the printing roller back and forth. After the printing on the first station is cleaned, the cleaning cotton is driven to move upward to the second station by the cleaning component 3 until the cleaning cotton is in contact with the surface of the printing roller on the second station, and then the cleaning is continued by the transport component.

[0035] In the above implementation process, when cleaning the printing roller, both workstations can only perform fixed operations on the printing rollers of the same size. This results in that when facing multiple printing rollers of different lengths, it is impossible to select a suitable fixed distance according to the actual situation, and only other cleaning devices can be used, resulting in reduced work efficiency. In order to solve this problem, an adjustment component 4 is fixedly installed on the frame 1, and the adjustment component 4 is used to select a suitable fixed distance according to the actual situation. Specifically:

[0036] like Figure 1-Figure 2 and Figure 5 As shown, the adjustment assembly 4 includes a mounting frame 41 fixedly mounted on the frame 1, a stepper motor 45 is fixedly mounted on the mounting frame 41, a lead screw 44 is fixedly mounted on the output end of the stepper motor 45, a slider 42 is threadedly mounted on the lead screw 44, and a slide rail 43 is fixedly mounted on the mounting frame 41, and the slider 42 is slidably arranged on the slide rail 43, and the slider 42 is fixedly connected to one set of mounting plates 25;

[0037] When the printing roller is fixed, the stepper motor 45 drives the lead screw 44 to rotate, thereby driving the slider 42 to move, and due to the setting of the slide rail 43, the moving direction of the slider 42 is fixed. At this time, the slider 42 drives the mounting plate 25 to move, thereby driving the fixing component 2 to move, so that the appropriate installation distance can be selected according to the actual length of the printing roller.

[0038] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
