DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Please refer to Figure 1-Figure 2 , a packaging bag printing ink cleaning device, comprising a workbench 1.

[0021] In the specific implementation process, Figure 1 and Figure 2 As shown, a mounting frame 2 is fixedly mounted on the top of the workbench 1 , a printing roller 3 is rotatably arranged in the mounting frame 2 , an ink scraping assembly 4 is arranged on one side of the printing roller 3 , and a cleaning assembly 5 is arranged above the printing roller 3 .

[0022] The ink scraping assembly 4 includes a moving rod 41 slidably arranged inside the mounting frame 2, a fixed cylinder 42 is fixedly connected to the bottom of the moving rod 41, a spring 43 is arranged inside the fixed cylinder 42, a connecting rod 44 is arranged at one end of the spring 43, and a scraper 45 is fixedly connected to one end of the connecting rod 44.

[0023] The connecting rod 44 is slidably inserted in the fixing tube 42 , and the inner wall of the scraper 45 is in contact with the outer side of the printing roller 3 .

[0024] The cleaning assembly 5 includes a lifting rod 51 slidably arranged on the inner wall of the installation frame 2 , a mounting seat 52 is fixedly connected to the bottom of the lifting rod 51 , and a sponge 53 is inserted into the inner wall of the mounting seat 52 .

[0025] It should be noted that: after the printing equipment has finished printing the packaging bag, the printing roller 3 stops rotating. At this time, the ink has not yet completely solidified. By pushing the moving rod 41, the inner wall of the scraper 45 is attached to the printing roller 3. Under the elastic force of the spring 43 in the fixed cylinder 42, the connecting rod 44 and the scraper 45 are tightly attached to the printing roller 3. Then, the sponge 53 is inserted into the mounting seat 52, and the lifting rod 51 is moved downward to press the sponge 53 against the outer side of the printing roller 3. Then, by rotating the printing roller 3 counterclockwise, the scraper 45 scrapes off the ink on the printing roller 3. The small amount of ink remaining on the surface of the printing roller 3 will be absorbed by the sponge 53, and the ink on the surface of the printing roller 3 will be wiped off by the sponge 53, so that the ink on the surface of the printing roller 3 is completely cleaned under the dual cleaning of the scraper 45 and the sponge 53. After the cleaning is completed, the moving rod 41 and the lifting rod 51 are moved to move the scraper 45 and the sponge 53 away from the printing roller 3, and then the sponge 53 is pulled out from the mounting seat 52, and the sponge 53 is cleaned and reinstalled into the mounting seat 52, and the next printing operation can be carried out. It has the advantages of simple operation and good cleaning effect.

[0026] A through slot 6 for use with the moving rod 41 is provided on the top of the installation frame 2 , a moving block 7 is fixedly connected to the top of the moving rod 41 , a positioning screw 8 is threaded inside the moving block 7 , and the bottom end of the positioning screw 8 abuts against the top of the installation frame 2 .

[0027] A fixing screw 9 is screwed to one side of the mounting frame 2 , a moving groove 10 for use with the fixing screw 9 is opened on one side of the lifting rod 51 , a knob 11 is fixedly connected to one end of the fixing screw 9 , and a limiting plate 12 is fixedly connected to the top of the lifting rod 51 .

[0028] It should be noted that: when the moving rod 41 slides in the through groove 6, the moving block 7 moves on the top of the installation frame 2, and the tops of the fixed blocks on both sides of the moving rod 41 move in contact with the top of the inner cavity of the installation frame 2, so as to guide and limit the moving rod 41. After the moving rod 41 is moved, the positioning screw 8 is screwed to make its bottom end abut against the top of the installation frame 2, so as to position the moving rod 41. When the lifting rod 51 moves, the moving groove 10 slides on the outside of the fixed screw 9. The fixed screw 9 is rotated by the knob 11 to position the lifting rod 51. The limiting plate 12 limits the lifting rod 51 to prevent the lifting rod 51 from falling out of the installation frame 2.

[0029] The working principle of a packaging bag printing ink cleaning device provided by the utility model is as follows:

[0030] When in use, after the printing equipment has finished printing the packaging bag, the printing roller 3 stops rotating. At this time, the ink has not yet completely solidified. By pushing the moving rod 41, the inner wall of the scraper 45 is attached to the printing roller 3. Under the elastic force of the spring 43 in the fixed cylinder 42, the connecting rod 44 and the scraper 45 are tightly attached to the printing roller 3. Then the sponge 53 is inserted into the mounting seat 52, and the lifting rod 51 is moved downward to press the sponge 53 against the outer side of the printing roller 3. Then, by rotating the printing roller 3 counterclockwise, the scraper 45 scrapes off the ink on the printing roller 3. The small amount of ink remaining on the surface will be absorbed by the sponge 53, and the ink on the surface of the printing roller 3 will be wiped off by the sponge 53, so that the ink on the surface of the printing roller 3 is completely cleaned under the dual cleaning of the scraper 45 and the sponge 53. After the cleaning is completed, the movable rod 41 and the lifting rod 51 are moved to move the scraper 45 and the sponge 53 away from the printing roller 3, and then the sponge 53 is pulled out from the mounting seat 52, and the sponge 53 is cleaned and reinstalled into the mounting seat 52, and the next printing operation can be carried out. It has the advantages of simple operation and good cleaning effect.
