[0024] For the embodiment, please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] A self-cleaning press roller for papermaking, comprising two sets of equipment side plates 1 symmetrically distributed left and right. A roller body 2 is rotatably connected up and down symmetrically between the two sets of equipment side plates 1. A roller body cleaning mechanism 3 is arranged on the front side of the equipment side plate 1.

[0026] In this embodiment, please refer to Figure 2 and Figure 3 and Figure 4, the roller cleaning mechanism 3 includes a fixing plate 301 installed on the front side of the equipment side plate 1 and near the center. A rotating motor 302 is installed outside the fixing plate 301 on the left side. A driving shaft rod 303 is rotatably connected between the two fixing plates 301. One end of the driving shaft rod 303 passing through the fixing plate 301 and the output end of the rotating motor 302 are both fixed with gears 304 that are meshed with each other. A connecting plate 305 is fixed on the outer side of the driving shaft rod 303. A fixed cross bar 306 extending along the length direction of the connecting plate 305 is installed on the side of the connecting plate 305 away from the driving shaft rod 303. A positive and negative motor 307 is installed at the left end of the fixed cross bar 306. The output end of the positive and negative motor 307 passes through the inside of the fixed cross bar 306 and is connected with a lead screw 308. A lead screw sliding sleeve 309 is threadedly sleeved on the outer side of the lead screw 308. The other end of the lead screw sliding sleeve 309 is connected with a soft brush 310 to clean the surface of the roller 2 and scrape off stubborn impurities. A water spray head 311 is connected to the lower part of the soft brush 310 through a support rod. An inlet water hose 312 is connected to the water spray head 311. A control valve 313 is installed in the middle section of the inlet water hose 312. A rubber scraping plate 314 is fixed on the outer side of the fixed cross bar 306 and below the soft brush 310, and the dirt and impurities on the surface of the roller 2 will be scraped off by the rubber scraping plate 314;

[0027] A controller is arranged outside one of the fixing plates 301. The controller is respectively connected to the rotating motor 302, the positive and negative motor 307, and the control valve 313 through wires, and the connection method is electrical connection. Both ends of the driving shaft rod 303 are rotatably connected inside the fixing plate 301 through bearing seats. Both ends of the lead screw 308 are rotatably connected inside the fixed cross bar 306 through bearing seats. A rectangular groove for the lateral movement of the lead screw sliding sleeve 309 is opened on the outer side of the fixed cross bar 306. The length of the rubber scraping plate 314 is adapted to the length of the roller 2. The sides of the rubber scraping plate 314 and the soft brush 310 facing the roller 2 are in contact with the roller 2.

[0028] Workflow of the utility model: When it is necessary to clean the surface of the roller body, connect the water inlet hose 312 to an external water pipe, and then start the cleaning mechanism device. First, the rotating motor 302 drives the meshing rotation of the two groups of gears 304, so that the driving shaft rod 303 rotates slowly, and the connecting plate 305 drives the fixed cross bar 306 to an appropriate angle to ensure that the soft brush 310 and the rubber scraper 314 are in contact with the surface of the roller body 2. Then, when the roller body 2 rotates, the dirt and impurities on its surface will be scraped off by the rubber scraper 314. At the same time, the lead screw 308 is rotated by the positive and negative motor 307, and the lead screw sliding sleeve 309 moves horizontally under the thread drive. At this time, the water spray head 311 sprays water on the surface of the roller body 2 to make the impurities easier to be cleaned. At the same time as spraying water, the soft brush 310 also cleans the surface of the roller body 2 to scrape off stubborn impurities. After the cleaning of the two groups of roller bodies 2 is completed, the driving shaft rod 303 can be rotated to turn the fixed cross bar 306 outwards and downwards, so as not to affect the paper pressing. The whole process can intelligently clean the surface of the roller body through control, which is convenient to operate and will not affect the normal paper pressing, saving the cumbersome manual cleaning by the operator and saving time and physical strength.

[0029] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
