Guide sleeves 21 are fixed at the four corners of the movable plate 19, and guide columns 22 are slidably installed in the guide sleeves 21. The top of the guide column 22 extends out of the top of the guide sleeve 21 and is fixedly connected to the lifting platform 2. The electric telescopic rod 20 is started to drive the lifting platform 2 to perform lifting and lowering adjustment. Through the cooperation of the guide sleeve 21 and the guide column 22, the lifting platform 2 is more stable during the lifting process to avoid shaking.

[0032] In this embodiment, the lifting mechanism further includes a rectangular frame 3 fixedly mounted in the lifting platform 2, an operating panel 4 fixedly mounted in the rectangular frame 3, a slide plate 5 slidably mounted on one side of the operating panel 4, a collecting box 7 fixedly mounted on the side of the rectangular frame 3 away from the slide plate 5, the collecting box 7 is used to collect the used cleaning agent and the residue scraped by the scraper 12, and a movable box door is provided on one side of the collecting box 7 to facilitate cleaning by the staff;

[0033] Among them, there are two groups of slide plates 5, and a sliding plate 6 is fixedly installed between the slide plates 5. A liquid storage tank 8 for storing detergent is fixedly installed on the sliding plate 6. A liquid outlet channel connected to the liquid storage tank 8 is provided in the sliding plate 6. The side of the sliding plate 6 away from the liquid storage tank 8 is connected to several liquid outlet pipes 14, and the nozzles 17 are fixedly installed at one end of the liquid outlet pipe 14. The detergent in the liquid storage tank 8 passes through the liquid outlet channel in the sliding plate 6, the liquid outlet pipe 14 and then is sprayed onto the operating panel 4 by the nozzle 17 in turn, so that the detergent reacts with the residue on the operating panel 4, which is convenient for the scraper 12 to scrape off the residue.

One end of the threaded rods 15 are respectively fixedly connected to the rotating motors 13, and the slide plates 5 are respectively threadedly connected to the threaded rods 15. First, the rotating motor 13 is started to rotate the threaded rods 15, driving the slide plate 5 to slide in the rectangular frame 3, thereby causing the sliding plate 6 to slide as well.

[0035] Furthermore, two groups of guide rods 16 are fixedly installed in the rectangular frame 3 , and the slide plate 5 is slidably sleeved on the guide rods 16 , respectively. The guide rods 16 are used to improve the stability of the slide plate 5 when sliding in the rectangular frame 3 .

The first protrusions 11 and the second protrusions 10 are slidably connected. As the sliding plate 6 slides, the second protrusions 10 at both ends of the rectangular plate 18 continuously contact the multiple first protrusions 11 on both sides of the operating panel 4, so that the rectangular panel 18 is continuously lifted up and dropped, so that the sponge strip 9 at the bottom of the rectangular panel 18 spreads the detergent on the operating panel 4 evenly, so that the detergent is in full contact with the residue on the operating panel 4.

[0038] Finally, the cross-section of the scraper 12 is set to a parallelogram, and the scraper 12 is fixedly installed at the bottom of the sliding plate 6. The scraper 12 is used to scrape and clean the operating panel 4, and the scraped cleaning agent and residues fall into the collection box 7, thereby preventing the residues from solidifying and causing the operating panel to be uneven, thereby affecting the next printing quality.

[0039] Working principle: In the working process of the utility model, the rotating motor 13 is first started to rotate the threaded rod 15, driving the slide plate 5 to slide in the rectangular frame 3, so that the sliding plate 6 also slides, and at the same time, the detergent in the liquid storage tank 8 passes through the liquid outlet channel and the liquid outlet pipe 14 in the sliding plate 6 in turn and is sprayed onto the operating plate 4 by the nozzle 17. At this time, as the sliding plate 6 slides, the second protrusions 10 at both ends of the rectangular plate 18 continuously contact the multiple first protrusions 11 on both sides of the operating plate 4, so that the rectangular plate 18 is continuously lifted and dropped, so that the sponge strip 9 at the bottom of the rectangular plate 18 spreads the detergent on the operating plate 4 evenly, so that the detergent is in full contact with the residue on the operating plate 4, and then the operating plate 4 is scraped and cleaned by the scraper 12 fixedly installed at the bottom of the sliding plate 6, and the scraped detergent and residue fall into the collection box 7 fixedly installed at one end of the operating plate 4, which avoids the unevenness of the operating plate caused by the solidification of the residue, affecting the next printing quality.
