[0024] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] Please refer to Figures 1 to 3 As shown, a paper drying cylinder outer wall cleaning device of the present invention includes a lifting mechanism, a frame 8, a dirt-drawing mechanism and a dirt-cleaning mechanism. The upper part of the lifting mechanism is driven and connected to the frame 8, the upper part of the frame 8 is provided with the dirt-cleaning mechanism, and the lower part of the frame 8 is provided with the dirt-drawing mechanism.
[0026] The cleaning mechanism includes a steam cleaning component and a scraping component. The steam cleaning component is located above the dirt-attracting mechanism and is connected to the upper part of the frame 8. The scraping component is located above the steam cleaning component and is connected to the frame 8.
[0027] The scraping assembly includes a first linear drive 18, a moving part 10, a slider, a slide rail 9, a first scraper 11, and a second scraper 12. The slide rail 9 is disposed above the steam cleaning assembly and is fixedly connected to the frame 8. The moving part 10 is slidably connected to the slide rail 9 via the slider. The first linear drive 18 is connected to the frame 8 and is linearly driven to one side of the moving part 10. The first scraper 11 is disposed on the upper part of the other side of the moving part 10, and the second scraper 12 is disposed on the lower part of the other side of the moving part 10. The length of the first scraper 11 is greater than that of the second scraper 12.
[0028] The working principle of this utility model is as follows: In actual production and use, when it is necessary to clean the outer wall of the drying cylinder, the cleaning device can be moved to the side of the drying cylinder. Then, according to the height of the drying cylinder, the lifting mechanism is operated, so that the lifting mechanism drives the cleaning mechanism and the dirt-drawing mechanism to move to a suitable position, so as to fit with the outer wall of the drying cylinder. Then, the first linear drive 18 is operated, so that the first linear drive 18 drives the first scraper 11 and the second scraper 12 to move towards the drying cylinder through the moving part 10 until the first scraper 11 and the second scraper 12 fit with the outer wall of the drying cylinder. Then, the steam cleaning component is operated, so that the steam cleaning component sprays steam onto the part of the drying cylinder below the second scraper 12, so that the chemical substances adhering to this part are softened under the action of steam. Then, the drying cylinder is operated, so that the drying cylinder rotates clockwise, so that the softened chemical substances are first scraped off by the second scraper 12, and then scraped off by the second scraper 12 a second time, so that the sewage and stains fall into the dirt-drawing mechanism for extraction.
[0029] Furthermore, the steam cleaning assembly includes a steam cleaner body 2, a water inlet pipe 1, a steam outlet pipe 21, and a steam nozzle 13. A water inlet is provided on one side of the steam cleaner body 2, and a steam outlet is provided on the other side of the steam cleaner body 2. A water inlet pipe 1 is provided on the water inlet, and the steam outlet is connected to the steam nozzle 13 through the steam outlet pipe 21. The steam nozzle 13 is located below the moving part 10 and is detachably connected to the surface of the frame 8.
[0030] As can be seen from the above description, when it is necessary to clean the outer wall of the drying cylinder, cleaning water can be introduced into the steam cleaner body 2 through the water inlet pipe 1. Then the steam cleaner body 2 turns the cleaning water into steam and introduces it into the steam nozzle 13 through the steam outlet pipe 21, so that the steam nozzle 13 sprays steam onto the outer wall of the drying cylinder, so that the steam softens the chemical substances adhering to the outer wall. Then the drying cylinder is operated. When the drying cylinder rotates, the first scraper 11 and the second scraper 12 clean and scrape off the softened stains.
[0031] Furthermore, the sludge-guiding mechanism includes a guide plate 20, a rubber support plate 3, a sliding key, a second linear drive component 19, and a sludge collection box 17. The guide plate 20 is inclinedly arranged at the lower part of the frame 8, and a guide groove is provided at the upper part of the guide plate 20. A sliding groove adapted to the sliding key is provided on the frame 8. The guide plate 20 is slidably connected to the sliding groove through the sliding key. The second linear drive component 19 is detachably connected to the frame 8 and linearly driven connected to the guide plate 20. The rubber support plate 3 is provided at one end of the guide plate 20 near the first scraper 11, and the sludge collection box 17 is provided below the other end of the guide plate 20 away from the rubber support plate 3. The sludge collection box 17 is connected to the frame 8.
[0032] As can be seen from the above description, it is beneficial to adjust the position of the guide plate 20 according to the outer wall of the drying cylinder, so that the second linear drive 19 can be operated. The second linear drive 19 drives the rubber support plate 3 to move towards the outer wall of the drying cylinder through the guide plate 20 until the rubber support plate is in contact with the outer wall of the drying cylinder. This allows the wastewater scraped off by the first scraper 11 and the second scraper 12 to be guided and collected through the guide plate 20. Subsequently, the wastewater is introduced into the sludge collection box 17 for collection through the guide groove on the guide plate 20.
[0033] Furthermore, the lifting mechanism includes a base 5, a third linear drive member 14, a slide rod 15, and a lifting plate 6. The lifting plate 6 is slidably connected to the base 5 around its perimeter via the slide rod 15. The lower part of the third linear drive member 14 is connected to the base 5, and the upper part of the third linear drive member 14 is linearly driven connected to the lower part of the lifting plate 6. The frame 8 is fixedly connected to the upper part of the lifting plate 6.
[0034] As can be seen from the above description, when it is necessary to adjust the height of the cleaning mechanism according to the height of the drying cylinder, the third linear drive 14 can be operated, so that the third linear drive 14 drives the frame 8 to move through the lifting plate 6, so that the cleaning mechanism moves to a suitable height for cleaning under the drive of the frame 8.
[0035] Furthermore, it also includes self-locking casters 4, with four sets of the self-locking casters 4 provided at the bottom of the base 5.
[0036] As can be seen from the above description, it is beneficial for the cleaning device to be moved to a suitable position by the self-locking caster 4 and then fixed by the self-locking caster 4 to prevent the cleaning device from moving during the cleaning process.
[0037] Furthermore, the sludge collection box 17 is provided with a sludge outlet 16.
[0038] As can be seen from the above description, it is beneficial for the sewage in the collection tank 17 to be discharged more effectively through the drain outlet 16.
[0039] Furthermore, it also includes a PLC controller 7, which is electrically connected to the lifting mechanism, the sludge-drawing mechanism, and the sludge-cleaning mechanism.
[0040] As can be seen from the above description, it is beneficial to adjust the parameters of the paper drying cylinder outer wall cleaning device through the PLC controller 7, and to make it more convenient for operators to operate the paper drying cylinder outer wall cleaning device. Example 1
