[0023] Example

[0024] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0025] like Figs. 1-3 As shown, a scraping mechanism for a printing roller of a label printing machine includes a housing 1 and a printing roller 2 disposed inside the housing 1. The two ends of the printing roller 2 are rotatably connected to the inside of the side walls of the housing 1. A screw 3 is disposed below the printing roller 2 and is connected to the printing roller 2 through a transmission mechanism. Two sets of moving mechanisms are symmetrically arranged on the screw 3. A U-shaped scraper 10 and a flat scraper 11 are respectively disposed at the two ends of the two sets of moving mechanisms. A mounting frame 12, a control panel 13 and an outlet 14 are disposed on the outer side of the side wall of the housing 1. A servo motor 15 is disposed inside the mounting frame 12. There are two outlets 14, and each outlet 14 is provided with a threaded cap 18.

[0026] The transmission mechanism comprises a driven wheel 5 sleeved in the middle of the printing roller 2 and a driving wheel 4 sleeved in the middle of the screw rod 3, the driving wheel 4 and the driven wheel 5 are provided with the same transmission belt 6, a servo motor 15 can drive the printing roller 2 and the moving mechanism simultaneously, thereby reducing the working cost; the output shaft of the servo motor 15 penetrates through the box body 1 and is connected with the screw rod 3, the free end of the screw rod 3 is rotatably connected with the inner side wall of the box body 1 through a bearing, and the screw threads of the screw rod 3 on the two sides of the driving wheel 4 are opposite.

[0027] Both groups of moving mechanisms comprise a sliding block 7 arranged on the screw rod 3, the top and bottom of the sliding block 7 are provided with a first electric telescopic rod 8 and a second electric telescopic rod 9, the first electric telescopic rod 8 is connected with a U-shaped scraper 10, the second electric telescopic rod 9 is connected with a plane scraper 11, the screw rod 3 and the sliding block 7 drive the second electric telescopic rod 9 to move back and forth, when the plane scraper 11 moves from the outlet 14 to the direction of the three-prism 17, the second electric telescopic rod 9 drives the plane scraper 11 to approach the bottom of the box body 1 infinitely, so that the cleaning is complete; when the plane scraper 11 moves from the three-prism 17 to the direction of the outlet 14, the second electric telescopic rod 9 drives the plane scraper 11 to rise upward, away from the bottom of the box body 1, thereby preventing the ink at the bottom from being brought back reversely. The second electric telescopic rod 9 and the sliding block 7 are further provided with a U-shaped frame 16.

[0028] The middle of the inner bottom side of the box body 1 is provided with a three-prism 17, due to the existence of the driving wheel 4, the two plane scrapers 11 cannot completely overlap, thereby causing the ink to possibly accumulate on the bottom of the box body 1 of the driving wheel 4, the existence of the three-prism 17 enables the ink in the partial area to slide down along the slope of the three-prism 17, and finally be scraped away by the plane scraper 11.

[0029] The servo motor 15, the first electric telescopic rod 8 and the second electric telescopic rod 9 are electrically connected with the control panel 13.

[0030] Working principle: when the ink on the printing roller 2 needs to be cleaned, the first electric telescopic rod 8 is driven upward by the control panel 13 until the U-shaped scraper 10 cleans the printing roller 2, the screw rod 3 is driven to rotate by the servo motor 15, thereby enabling the sliding block 7 to move on the screw rod 3, and due to the existence of the transmission mechanism, any surface of the printing roller 2 can be cleaned, then the second electric telescopic rod 9 is started, the plane scraper 11 approaches the inner bottom side of the box body 1, the cleaned ink is cleaned, and finally is discharged through the outlet 14.

[0031] Therefore, the label printing machine printing roller scraping mechanism with the above structure can clean the accumulated and hardened ink on the printing roller, improve the printing quality of the label, clean and discharge the cleaned ink, and prevent the accumulation from affecting the use of the equipment.

[0032] It should be pointed out finally that: the above examples are only used to illustrate the technical solutions of the utility model and not to limit them, although the utility model has been explained in detail with reference to the preferred embodiments, ordinary skilled in the art should understand that: its still can modify or equivalent replace the technical solutions of the utility model, and these modifications or equivalent replacements also can not make the modified technical solutions deviate from the spirit and scope of the technical solutions of the utility model.
